N. Kovalev/ /Text/ It is well known that at the present stage of the scientific and technical revolution mankind's power and technical equip.ment greatly exceeds its capacity for making prompt and substantiated decisions /7/. The use of mathematical methods and modern computer hardware in the problems of man's decision making in various, in- cluding conflict, situations is a promising way of eliminating this disproportion. ~ The. appearance of the mathematical game theory, which studies formal riecision making models under conflict conditions, was a natural stage in the development of inves- tigations in this area. ~ The limiting possibilities of this theory are clearly outlined /1/. One of its limitations is the fact that, when the real behavior of people carrying out their activity in accordance with the infinite diversity of their needs is modeled within the framework of the game theoxy, the psychological rules of this activity are ei- ther ignored completely, or are taken into account in a generalized manner, on the average, whereas the "application of general psychological rules to life should al- ways be mediated by tha knowledge of individual differences" /12/. On the other hand, psychology, which has long included decision ma.king problems in the sphere of its interests, cannot bypass the positive experience accumulated with the formal- logical approach to the investigation of decision ma.king processes in conflict sit- uations, in particular with the use of computers for the solution of various prob- _ lems pertaining to this area. At the same time, it is appropriate to note that an active involvement of computers in the process of man's decision making, along with expanding his intellectual capabilities, at times leads to certa~n changes in the "style" of human thinking by includin& in its structure operations, the possibility �or the performance of which is offered to man by computers, because "not the de- ~ termining tendency, that is, goal (beginning and end), determines the entire course and structure of the process, but the average moment. T'he properties of the tool are the functional center and they determine the entire course of processes, their - change and so forth. The entire specificity of behavior is determined by the aver- age member of the instrumental act" /2/. rn the basis of the expressed view, turning directly to the problem o.f development - of a procedure �or an experimental investigation of individual decision making characteristics in conflict situations and, at the same time, taking into account 1 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00854R004400080032-4 FUR OFFICI4L USE ONLY the significant potentiala of games in the modeling of such situations, as well as ~ the role and possible functions of computers in their resolution, we considered it ~ advisable to include a computer in the experiment, formulating it in the form of a game between man and computer. The introduction of a computer into an experimental siti~:ation makes it possible to solve a number of diverse problems, whose concreti-- zaticn depends on the goals and canditions of the experiment. By means of it it is possible to create a"problem environment" imitating conflict conditions. It can act in the role of man's assistant and opponent and.makes it possible directly in the course of the experiment to immediately change its conditions depending on the resuits and to vary the methods of training th~ tested individual (in ''adviser" and "instructor" modes) and the computer's "strength of the game" (in the "opponent" mode) and so forth. The inclusion of a comput~r in the experiment also makes it possible to solve the problem of an objective recording of the characteristics of behavior of the tested individuals during the game for the purpose of detecting their individual charac- teristics in the subsequent analysis. The package of applied computer programs (the Alisa automated logir.al game system) designed for games between man and com- puter, which was especially developed at the laboratory for mathematical modeling o� mental processes of thz Scientific Research Inatitute of General and Pedagogical Psycl~ology of the USSR Academy of Pedagogical Sciences, includes ? dossier system for every tested individual, where ob~ective data on the tested individual, the moves and answers of the tested individual and the computer, the time spent on thinking them out and r_he elements of the dialog between man and computer are re- corded. At present work is done on the furthc:r expansion of the capabilities of the Alisa system. Its organization envisages the extraction of information from the computer memory in various combinations and print-out for a subsequent anal- ysis of r.he data files unif ied according to the criteria of interest to the exper- imenter--methods of the game, its time parameters, the type of thinking of tested individuals, their age, sex and education and so forth. Since a game always represents a conflict of personalities and antagonism between _ characters, the selection of a computer as man's game partner also has the advan- tage that it makes it possible to fix at a permanent level the characteristics of one "personality" (computer) for the purpose of creating the same experimental con- ditions for all tested individuals, at the same time, giving the experimenter wide possibilities of varying these characteristics in accordance with the specific pur- poses of the experiment. The selection of a computer as a tool of investigation was only the first step in the development of the procedure o~ interest to us. The next step consisted in the solution of certain individual problems, that is: 1) sel.ection of specific models of eonf lict situations (games) most suitable for the investigation and recording of individual decision making characteristics; 2) performance of preliminary experiments for the purpose of determining the pos- sibil.ities of the procedure for detecting the characteristic features manifested by various tested individuals in the course of the game; 2 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2047/02/09: CIA-RDP82-00850R000404080032-4 _ FOR OFFICIAL USE ONLY 3) preliminary classification of individual characteriscics according to the stages of a conflict activity. The results of the solution of the indicated problems are briefly presented below. 1) When selecting games, we tried to reflect the following ~haracteristic features in the model of a conflict situation: a) its specific duration and the need to establish a sequence of specific opera- tions (perhaps even one-type operations) for its resolution; b) changeability of the situation in the process of its resolution and the need to take into aecount the results of previously performed actions; c) the need for decision making under conditions of uncertainty in combination with - the possibility of applying logical actions for reducing it; d) a sufficient diversity of final situations denoting a victory in this conflict; e) a sufficient diversity of ways of attaining a victory and their nonequivalence. f) the possibility of attaining a victory at any stage of the conflict, including the initial stage. Furthermore, the following condition was made: Ttie game should min~mally affect the specific habits or professional experience of the tested individuals. As a result of an analys3s of various games, three out of the set of variants of the logical game "Symbols" representing modifications of the Master-mind game known in our country by the name "Bulls and Cows" were selected as the first model of a conflict situation meeting the enumerated requirements /3/. In general form the "Symbols" game can be described as follows. A set containing n various elements (figures, letters, symbols, concepts and so forth) is announced to both partici- pants in the game ("opponents"). Each participant secretely from the other must make from them an ordered sequence containing m elements (in general there are no constraints on n and m). The task of the participants ~is to determine the sequence tiiought of by the opponent in a minimum number of moves. The moves are made in turns. Each move consists of the "trial" of one participant and the "answer" that another participant gives to this "trial." Any ordered sequence of m symbols forming part of the announced set of n elements selected by the participant in the game is a "trial." Two numbers are the "answer." The first (number of "bulls") is equal to - the number of elements of the "trial," which in the held place and type coincide with the elements of the sequencethoughtof and the second ~number of �tcows") is equal to the number of elements of the "trial" forming part of the sequencethought of, but not coinciding with them in place. The participant who f irst got the answer--m "bulls," zero "cows"--is cor.sidered the winner. The "Symbols" game is finite. How- ever, the number of personal moves (strategies) in it is C=nm, which offers the ex- perimenter wide possibilities of varying the conditions of the game for the purpose of disclosing the characteristics of behavior of the tested individual in the range from the finite to inf inite game, which the "Symbols" game seems to man with a growth of m and n. 3 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 FUP. OFFICIAL USE ONLY In the first two selected varianta of the game f igures served as elements of the ~ announced set: for the first variant n1=5, for the second variant n2=10 and for ; both variants m=5. A repetition of the same figures in the number thought of was prohibited and the use of zero in a high order was permitte3. In such f orm the se- lected variants of ttxe "Symbols" game maximally approximated the "Bulls and ~ows" game. It can be easily seen that the probability P1 of accidentally guessing the nun~ber thot~ght of during the first move for the first variant is inverse to the num- ber of permutations of 5 elements, that is, P1=1/5!=1/120. For the second variant this probability is inverse to the number of permutations of 10 elements taken 5 at a time, that is, P1=1/ASlo=1/30240. There are rules making it possible to sharp- ly increase (up to a unit) the probability of accidentally guessing the number - thought of with the subsequent move. However, as the experiment showed, no ,~ested in- dividual used these rules, even when they were explained to him by the experimen- ter. The tested individuals tried to reduce the uncertainty of the situation in another way, using various methods, in which logical steps and intuitive guesses were combined. The inclusion of a computer in the experiment also made it possible to realize a third variant of the "Symbols" game, in which at the beginning of *_he game the com- puter does not at all "think of" a specific sequence of symbols, but gives the tested individuaL according to a program previously fixed by the experimenter in the f~rm of answers~ inGtructions for specific subsets of the set of answers pos- sible with the given trials o~ the tested individual. This means that for any sequence of trials of various tested individuals the seqtience of answers Oi for each of them will appear the same (f or example: 01=02; 02=02; 03=02; 04=21; 05=21; 06=50. Here the f irst f igure of the answer means the number of "bulls" and the second, the number of "cows"), which creates the same initial situation f or all the tested individuals and provides especially "pure" experimental conditions f or a comparative study of the game strategies used by man. It is appropriate to note ; that, in practice, the realization of ~uch a game variant without the help of a computer is impossible. ' 2. A total of 49 tested individuals aged 17 to 53 participated in the preliminary experiments. A total of 145 records characterizing the game process of the tested " individuals in si.x experimental series devoted to various aspects of the investi- gation were obtained. The detection of the methods and techniques of the game used by the tested individuals was the main problem in the first series (25 experi- ments with 12 tested indivi.duals), which was preliminary and was ccnducted without the participation of a computer. The same problem (incidentally) was solved in the remaining f ive series, but against the background of other goals. Three ser- ies were devoted to a clarification of the characteristics of the process of the game in its above-mentioned three variants, one series was a control seri:.s (two zested individuals with different types of thinking, five sets with each) and the sixth series was devoted to an attempt to correct in individual tested people the errors characteristic of them and to form in them elements of the theoretical type of thinking. In this section we will dwell. only on a brief description of the characteristic methods and techniques of the game used by the tested individuals, which were dieclosed in the experiment. The number of moves in a set in all the series ranged from 2 to 25. Such a di- _ versity of the "length" of a set was clearly dependent on the methods and tech- - niques of the game used by the tested individuals. The replacement of one 4 FOR OrFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 FOR OFFiCIAL USE OAILY element (f igure) in the next trials of the tested individual was the simplest. This is a reliable method of detecting the unknown set X(number thought ofl , but, using it, the tested individual arrives at a solution comparatively s1ow1Y. The method of replacing several figures in the next trials is "quicker." However, - here the tested individual runs the risk of encountering a multialternative hypoth- esis, but the selection of one alternative without a sufficient basis often leads - to a prolongatian of the game. The tested individuals using this method can be divided into two groups depending on the time spent on considering a move. An in- vers~_on of the figures left in a trial accompanying the replacement is a variant of this technique. The method of constructing the unknown number on the basis of an analysis of as complete a set of hypotheses aspossible is considerably differ- - ent from these techniques of substitution of elements {replacement of figures). Furthermore, a s.ingle tested individual, who had extensive experience irc the game and was familiar with the machine algorithm of conducting it, demonstrated a meth- od totally uncharacteristic of man and more auitable for realization cz a computer, completing th~ game in 1 hour and 25 minutes with only six moves, making only 38 s~ipport records and effectively reducing the sorting of the remaining 30,202 num- bers orally on the basis of simple logical considerations. A stable use of any one method mostly leads to a prolongation of tl-~e game, as their alternatian leads to its shortening. The use by the teated individuals of some very simple rul~es of the game als~ contributes to this. However, not all the tested individuals "discover" them for themselves and, having discovered them, do not always use them. In fac t, the determina tion of characteristic methods and techniques and the de:ec- tion of typical errors of the tested individuals represent the preliminary stage in the analysis. The analysis proper begina with the advancement and check of - hypotheses on the causes of the observed phenomena, that is, change iu methods, appearance of logical errors, domination in the tested individuals of certain char- acteristics in the process of the game and so forth. Here it is possible to make an attempt to reconstruct the course of reasoning of the tested individual. However, owing to the ambiguity of the cauaea of a certain action, the resuits of such at- tempts are also distinguished by an ambiguity. Hence the need to analyze.the ex- perimental material at least at two qualitative levels. T.he described level of analysis, giving the investigator only the initial material for a classif ication of the characteristic features manifested by the tested individuals in the course of the game, at the same time, suffers from a lack of principles f or its substantia- tion and explanation. 3. The next, qualitatively new level of analysis is connected with the superposi- ~ tion of distinctive psychological coordinates on a sufficiently variegated picture of the methods and techniques of the game and their combiuations and alternation in time. In order to do this, we will f irst examine some approaches t~ the solution of the problem formi.ng the basis for the "Symbols" game as illustrated by its mo- dification "Bulls and Cows" with m=5 and na10, which, basically, was used in our experiment. Any sequence of 5 nonrecurrent figures in accordance with the condi- tions of the game are in a certain relationship with each of the 30,240 numbers, whicti can be thou~;l~t of jn its examined variant (we will designate this initial set by the symbol M). For example, the aequence 01234 with the number 43,210 is in the relation one "bull," four "cows" (conventionally 14), in the relation 00 with - 5 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 FOR OFF7CIAL USE ONLY the number 56,789 and in the relation 50 with itself. These relations can be con- sidered models of all the possible relations existing between other real objects. ; Then the finding of the unknown number in this game, in fact, represents the sin- gling out, from the set of objects similar to it, of a certain object, which, as it is investigated, is revealed in ever newer, previously unknown Yelations. The ays- tem of these relations represents sn important criterion of the unknown ob~ect. To reveal this system till the end meane to determine this object. In fact, if the answer 01=b1k1 (we will designate this relation with the symbol Ai) is received to the first trial of the tested individual II1=alblcldle1, this will mean that the un- known number enters a certain subset Mlc M, each element of which is in the xela- tion A1 with the trial II1. Similarly, if 82=b2kz (secon3 relation Az) is the an- swer to the second trial II2=a2b2c2d2e2, this will mean that the unknown number en- ters the subset M2~ Mp, each element of which is in the relation A2 with the trial IIz and so forth. From this it is possible to determine the optimum way of finding the system of relations A1i Az, Ak representing the significance test of the unknown number. Having received the answer O1 to the trial II1, it is necessary to determine the aubset M1, after which the trial IIZ should be selected not arbitrar- ily, but only from the elements of the subset Ml. Having received the answer 02, it is necessary to determine the corresponding subset M2c M1 and the trial II3 should be selected only from its elements and so forth. Obviously, with such a method of i selection of next trials the power of the subsets hll, Mz... will decrease, whic.h ultimately, will lead to the unknown number, to which the system of relations (sig- ~ nificance test) A1, Az, will correspond. This method formed the basis for the algorithm of operation of~e computer acCing as man's opponent in the game. The experiment showed that the computer most often determined the number thought of by the person in f iv~e or six moves (whereas the person did this in 9 or 12 moves, on the average), which, even if indirectly, confirms the optimality of this algo- rithm (of course, owing to fully understandable reasons, this algorithm is beyond the poweL of man's "unequipped" intellect. However, its use by means of a computer can serve as one of the examples of the effect of a tool (computer) new for man on the "style" and structure of his thinking activity, which was discussed above). i 1'h.is is the essence of the first approach to this problem. In our opinion, it re- ; flects the understanding of the totaii;y of trials in ~ game as a single whole. Viewing the next moves of a game as a series of unconnected problems is quite the opposite to this method. The tested individuals' methods of conducting a game ac- _ tually observed in the experiment in all their diversity lie between these extreme approaches. With the exception of the above-mentioned single case of a"machine" solution o� a problem by atested individual, we did not observe an "integral" approach to it . At the same time, during the most unsuccesful game by a tested individual he con- nected at least three or four moves into a single system (apparently, there is no need to demonstrate that the unification of two moves as a minimum in a system is a necessary cundition for a nonrandom aolution of a problem). It is easy to perceive a direct relationship between the singled out appxoaches and the theoretical and empirical types of thinking described in the literature /6/. It is well known that theoretical thinking "is realized by means of a substantive ab- - straction (singling out by means of an analysis of cognizable phenomena of the re- lation initial for them) and a substantive generalization (presantation of a num- ber of phenomena as a system on the basis of the necessary connection)" /9/ in con- trast to empirical thinking, of which formal abstractions and generalization are 6 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2447/02/09: CIA-RDP82-00850R000400484432-4 FOR OFF'ICIAL USE ONLY characteristic. In theoretical thinking a separate phenomenon appears as an e1e- ment of a certain system of phenomena, which makes it possible to single out the - general principle of solution of a problem. In case of the same types of prob- lems this principle mak.es it possible to solve "on the spot" all similar problems. For the empirical type of thinking even the same types of problems seem relatively independent and new. A comparison of the two extreme approaches to a problem with characteristic aspects of theoretical and empirical types of thinking, which were described a~ove, deter- mined our selection of the principles of the theory of two types of thinking as the principles of classification of the obtained experimental material and its substan- tiation and explanation. The correctness of our selection is confirmed by the data in the literature on various approaches to the solution of problems by r~resenta- ti~es of the indicated types of thinking in various age groups /5/ and /8/, includ- ing those pertaining to one of the versions af the "Bulls and Cows" gaane with m-4 and n=10 obtained as a result of experiments with sen~.or schoolchildren /4/. Thus, the use of the experimental ~ethod proposed by us, whose basic characteristic is the inclusion of a computer in a game as man's opponent with a subsequent anal- ysis of the data obtained on the basis of the theory of substantive generalization, makes it possibie to hope for the detection of individual decision making charac- teristics in conflict situations and for their explanation with the characteris- tics of the type of thinking. At the same time, the further trend in research can be determined on the basis of the following considerations. The detection of the characteristics of thinking of two extreme types (empirical and theoretical) in training and problem solution was the object of many investi- gations in the area of typology of thinking. Numerous works stress the need for a - purposeful formation of the theoretical type of thinking /6/, /11/ and so forth. At the sar,ie time, V. V. Davydov also talks about its spontaneous formation, point- ing out that it is not formed in everyone and, if it is formed, then with "consid- erable flaws" /6/. Various thinking defects in adults with their~ontaneously formed types of thinking were investigated in a number of works /5/; /10/ and so forth. Our experiments have shown that only a negligible number of tested indi- viduals from the beginning and end of a game follow methods characteristic of the theoretical type af thinking, whereas many of them, along with the use of the ba- sic components of theoretical thinki.ng (analysis, reflection and an internal plan of actions) during some moments of a game, manifest themselves as typical "empiri- cists." A reverse process was observed in some tested individuals. Beginning a game as "empiricists," they gradually arrived at the elements of theoretical gene- - ralization. Tite totality of these data makes it possible to set the task of in- vestigation of individual characteristics of the "intermediary" type of thinking in conflict situations, in which, in our opinion, a significant number of the tes- ted individuals participating in the experiment should be included, and, along with a study of the conditions of formation uf the theoretical type of thinking, to make an attempt to detect the conditions under which its disintegration occurs. Hypothetically, it can include a limitation of the time for a game as a whole and for its every move separately, division of attention, increase in the volume of the material that must be retained in memory at the same time, increase in the ob- jective and sub~ective difficulty of a problem, sub~ectively evaluated degree of , the opponent's counteraction (his strength) and some other factors.

S. Goncharov/ ~ - /Text/ The investigation of the process of a search for a decision is of practical ' importance from two aspects. On the one hand, the study af the patterns and prin- ~ cipl~es of a search for a decision is generated by the need for optimization of mana- gerial labor, whose proportion ~in the total volume of occupational activity grows . constantly. From this point of view the search problem, which lies in the selec- . - tion of acceptable or optimal decisiona, f orms the basie for decision making. In this connection the problems of study of the procesa of a search f or a decision are included in the probZems of investigations of decision making /5/ and /7/. ~ On the other hand, the study of how man searches for a decision is generated by the need for improvement of computer programs. As is well known, a computer search for a decision, as compared with a search made by man, i,s still less economical. It is ~ connected with the sorting of a large number of variants and alternatives. A clar- ification of effective principles of a sear~h for a decision in man for the purpose of Cheir realization in machine programs is an important research task. The process of a search for a dec3sion is characterized by a specific strategy. The strategy represents the form of a search and the method of iCs organization. Both the�strategies af a machine search realized in computer programs and the stra- tegies characterizing_a_search and decision making in man are now studied inten- sively /5/, /9/ and /11/. Clarification of the dependence of the atrategy of a aearch for a decision on the . type of thinking is the object of our inveatigation. The eatablishment of such a dependence can expand the ideas of the poasibilities of the two methoda uf orienta- tion in reality and demonstrate the advantage of one over the other. The investigation was conducted in two stages. A diagnosis of the type of thinking according to especially developed methods was made at the f irst sCage. The charac- teristics of a search for a decision in tested individuals with a different type.of thinking were studied by means of the game method at the second stage. Before turning to a description of~ the methoda diagnosing the type of thinking, we will dwell on some theoretical principles forming the basis for the division of thinking into two types and for the construction of diagnostic methods. 1Q , ~ FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 ~ FOR OFFICIAL USE ONLY The teaching of two types of thinking is developed in the works of V. V. Davy- dov and his associates %2/. V. V. Davydov singles out two types of th~.nking-- empirical and theoretical. Empirical thinking is charaeterized by the fact that it reflects objects from the aspect of their external manifestations and conneC- - tions. Empirical thinking represents a"method of obtaining and utilizing sen- sory data by people possessing the faculty of speech... /2; 266/ and its basic function "lies in the classification of sub~ects and in the construction of a firm scheme of def initions" /2; 179/. In contrast to empirical, theoretical thinking is considered thinking "reflecting the internal connections of ob,jects and the laws of their movement" /2; 176/. Theoretical thinking has the area of objectively interconnected phenomena f orming an integral system as its special content. Theoretical thinking is characterized primarily by a special type of generalization, to which the process of analysis as a specific component of the- oretical thinking leads. Theoretical analysis is an "analysis, which, being per- formed on some one specific event or one problem, at the same time, discloses the internal conn~ction forming the basis for many particular manifestations of this event or this problem. Owing to ~hiss man seemingly "generalizes a certain range of events and problems on the spot" /2; 1847. Generalization through a long com- parison of aimilar facts and their gradual unification into a certain category is characteristic of empirical thinking. The characteristics of the described types of thinking are clearly re~vealed duX- _ ring the solution of a number of the same types of problems. With the theoret- ical method of solution an analysis of the ccnditions and requirements of one problem of a certain category makes it possible to disclose the general principle of solution of all the problems of this category and then right away to correctly solve all the remaining problems. With the empirical method man solves each sub- sequent problem through trials and errors as a relatively new and independent problem. Three basic companents are differentiated in theoretical thinking: analysis, reflection and internal plan of action. A theoretical analysis of the content of a problem represents the process of singling out the principle of the general method of its solution, which then seemingly is transferred to the whole cate- - gory of such problems "on the spot." Reflection lies in the sub~ect's use of his own method of action and in an examination of the basis for it. An internal plan of action is man's ability to act "mentally," ensuring the planning and perFormance of actions without the use of external supports. To detect the presence or absence of an analysis, a series of the same types of problems, from the nature of solution of which it is possible to judge the sin- gling out by the test~d individuals of its general principle,was used. The prob- lems were made up according to the principle of increasing difficulty. Anagrams (anagram is a word transformed through a rearrangement of the letters forming it) were selected as pr.oblems. The following series of anagrams was offered to the tested individuals: 11 � FOR OFF[CIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2047/02/09: CIA-RDP82-00850R000404080032-4 FOR OFFICIAL USE ONL1l ' ~ ~ 1) J1BI40 4) EP~~ 7) O~CP?N~IPH 2) PAS~I 5) P14~~'1d 8) 7II'BYEINAK ~ 3) YfIICC 6) AII~IPPH 9) FBI~T~ ~ . ~ The following problem was given: "According to these anagrams to finii the words ~ from which they are formed." . These anagrams were obtained from some words.through a.place change of two neigh- boring letters in pairs. If the tested individual solves each such problem as a new one, not singling out the general principle of their structure, this indicates an orientation to their external, unessential criteria. However, if the tested individual discovers this principle during the solution of one or two problems and then immediately and correctly uses it during the solution of all the other prob- - lems, this means that he analyzed the first problems and during the solution of the remaining ones leaned on the f ound initial relation of their condition. Two methods were devised for the detection of reflection. The f irst was a modifi- cation of th~ method used by A. Z. Zak /3/. Each of the methods represents three single-type problems, which the tested individual is asked~to solve. The problems ~ are.made up so that the first and third have a common method of solution. The sec- ond problem differs from'them in the method of solution. After a successful solu- tion of all the problems the tested individual is asked to classify them. The . ~ problems were selected so that they presupposed a classification both according to : their external criteria and according to the method of solution. If the tested in- dividual determined that the met~od of~solution of the first and thir3 problems was common and the second differed fr.om it, he made the following classification ~ according to the method of problem solving. Such a classification points to the presence of reflection. Otherwise the classification was made on the basis of the , external criteria of the problems, which were detected through a�comparison of , their conditions. Such a classif ication shows'the absence of reflection. , The first method of detecting reflection was.made up from the following problems: ~ ) ~gI',iTF~['_ I'~BpC~IC (four moves) ~ 2) g(~3XQI,y~ 33~IIBmTII~i~f (four moves) _ . 3) KEMQOBNP MQCTHPOB (four moves) - ~ At first the tested individual must transform in four moves the initial arrange- - ment of the letters (group of letters arranged in the left part of the sheet) into. the final arrangement (group of letters arranged in the right part of the sheet). A mutual rearrangement of two letters so that they change places is a move. Next the tested individual is asked to select one of the fo~.lowing views and to sub- stantiate his selection: 1) All the problems are similar. 2) All the problems are different. 3) The first and second problems are similar. - 4) The second and third problems are similar. 5) The second and third problems are similar. - 12 ~ FOR OFFICIAL USE ONLY ' ~ APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 FOR OFFICIAL USE ONLY The second method of disclosing reflection represents the following three problems: 1) Misha ie heavier than Slava {~(~o is the heavieat? Borya is heavier than Misha 2} Katya is darker than Vera ~o is the darkest? Vera is darker than Nina , 3) Nadya is more cheerful than Zina y,mo is the most cheerful? Lyuda is more cheerful than Nadya - As in the first method, the tested individual at f irst is asked to solve these problems, answering the questions raised in them. After that the tested individual decides which of the next three views is correct: 1) .All the problems are similar. 2) All the problems are different. 3) One problem is different from the other two. To reveal the level of development of the internal plan of action, a method made up of three problems of increasing diff iculty was used. A quick and correct solu- tion of problems of the second and third degree of difficulty can indicate a high level of developmen~ of the internal plan of action corresponding to the fourth and f ifth level (according to Ya. A. Ponomarev) /6/. However, the solution of the problem of the f irst degree of difficulty alone points to a low level of develop- ~ ment of the internal plan of action coxreaponding to the third level (according to Ya. A. Ponomarev). In the offered assignments the tested individual is required in a specific number of moves to arrange the letters in the same way as the figures stand, that is, the same letters should be arranged in the squares where the same figures are. A simultaneous mental shif t of any two letters is taken as one move. Students in lower courses of the Moscow Oblast Pedagogical Institute imeni N. K. Krupskaya, students at the Smolensk Pedagogical School and seniors at the school No 10 in the city of Mytishchi (a total of 73 people) participated in the testing of the described m~thods. The test results showed the suitability of the developed methods f or a division of the group of tested individuals into groups depending on the nature of solution of the given problems. Seniors at Moscow schools and staff inembers and graduate students at one scientif- ic research institute took part in the basic series. In all 60 people were ex- amined in this series. According to the resulta of the examination Che tested individuals that partici- pated in it were divided into three groupa. Teated individuals who aucceasfully fulfilled the aseignments in respect to all the methoda and, thus, revealed the presence of analysis, reflection and a developed internal plan of action, u~ade up the first group including 18 people. This group was conventionally called the group of "theoreticians." Tested individuals that did not fully per�orm the assignments for analysis and ~ - reflection and showed an unstable solution of the assignments f or the internal plan of action formed the second group consisting of 32 people. This group re- ceived the conventional name of a group of "empiricists." 13 F~DR OFFIC1tAL US~ ONLY .

The tested individuals of this group did not reveal a stable analysis or reflection and showed a different c~egree of formation of the internal plan of action. For a clarification of the characteristics of the search for a decision in the tested individuals of .the three given groups the game method was used. Games of a varying content and~ame problems are widely used :Ln the investigation of man's thinking activity /8/ and /10/. They create conditions for conducting a search in maximally expanded forms an3 make it possible to f ix its complex time and space ' - dynamics. - The "Bulls and Cows" game was selected for the purpose of our investigation. The - game consists in a.correct guess by one player of the number thought of by another , player with the smallest number of moves. A four-digit number is thought of in such a way that all the figures in it are different. In every move the guessing person names a certain number, which aleo has four digits and different figures. The partner compares the number he thought of with the one mentioned.and reports the number ot "bulls" and "cows." A situation when the numbers thought of and mentioned have common figures standing at the same places is called a"bull" in this game. If common figures stand at different places, this is a"cow" /1/. 'i'he experiment �aas conducted by means of a computer. The computer "thought of " a number and advised the tested individual of the answer to his next move. Communi- cation between the tested individual and the computer was carried out through a specia3 terminal device. ~ The unknown number in the "Bulls and Cows" game can be represented in the form of an ordered set M={a, b, c, d}, which is a subset of the set N={1, 2, 3, 4, 5, 6, 7, 8, 9, 0}, Mc~N. - For purposes of investigation we decided to confine ourselves to an examination of games with the initiaZ situations 0-1 and 0-2 (0 "bull," 1"cow" and 0"bull," 2 "cows"). These initial situations are the most indef inite in the game. The prob- lem of a search for the elements of the set M from these initial situations is most difficult. ~ As an analysis of the obtained materials ehowed, substantial and most signif icant - differences in the strategies of a aearch for a decision in various groups of tes- ted individuals are revealed during the opening of the games. Subsequently, only the characteristics of a search for elements M during the opening, in the first three moves, were examined. This number of moves ia auff icient in this game in order to obtain the first unambiguous conclusions on the bel.onging of specific elements N to.the set M. We will confine ourselves to an examination of the search for the elements forming part of M, digreasing from a search for the place of these elements in M. The obtained experimental material makes it possible to single out _ three types of search strategies during the opening of a game. 14 ~ ' FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPR~VED F~R RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 FUR OFF[CIAL USE ONLY Strategy A.

The relation H=K, where R is the total number of "bulls" and "cows" in response to a given mo~�e and H is the number of figures di this move transferred to the next move, is an expression of this strategy.

A search for the elementa of the aet M ia made through the establish- ' ment of a single connection among them. ~.'he equality H=3 is the expression of this strategy. The replacement of one alement of this move, when the response to the next move is changed, presupposes a clarification of the belonging of both the _ replaced and replacing element to the unknown set. A strictly disjunctive connec- tion established among these elements is the basis for this strategy.

A search for elements is made through the singling out of a system of connections among the~elements of the game situation. This strategy is realized _ during the construction of a third move, if K1=K2. The establishment of a con~unc- tive connection between the replaced and replacing elements and a weakly dis3unc- tive connection between these elements and three others forming part of the first and second moves is the basis for this stra tegy.

Hence it can be concluded that the search according to strategies B and C requires an analysis and reflection and its performance presupposes a high level of development of the internal plan of action. However, the search charac- terized by strategy is made without an analysis or reflection and does not require a high level of formation of the internal~p lan of action. Analysis ensures the performance of a search according to the connections of the elements of game sit- uations. At the same time, analysis most explicit in its own theoretical form is revealed in the realization of strategy C. Here the search is made on the basis of a system of connections constructed by the tested individual who is a"theore- tician." Reflection, which is an aspect of theoretical analysis, makes it possi-- ble to examine the basis of the actions proper and to find the basis most accept- able under given conditions.

PSYCHOPHYSIOLOGICAL DESCRIPTION OF FATIGUE BASED ON ACTIVATION INDICATORS Moscow VOPROSY PSIKHOLOGII in Russian No 3, May-Jun 81 pp 38-48 [Article by G. A. Stryukov, T. N. Dolgolenko and 0. A. ICAnopkin] [Textj Concern with the reliability of operators controlling complex technical systems has imparted new importance to a problem that is not at all new--that of _ diagnosing fatigue in man. Although studies devoted to psychophysiological descrip- tion of fatigue number in the hundreds each year, the problem rema.ins far from solved, ~ both from the aspect of deep theoretical development and from the aspect of applied use of the obtained results. McFarland believes that "absence of an understanding and of control over what we call fatigue is one of the most confused problems of our life." He also adds that "the term fatigue may be likened to the word subconscious, which has become a convenient category by which to designate phenomena that are not , altogether understood but nevertheless real" l(20), p 2). Were we to analyze studies of fatigue, the first thing we would notice is the un- reliability and variability of the "witnesses of fatigue," be they sub5ective symptoms of tiredness, shifts in work effectiveness or changes in psychophysiological funetions (18). 7.'here are practically no indicators which would unambiguously signal the onset of fatigue, and at present it is impossible to descri.be fatigue as a clearly delimited syndrome having a limited set of mutually correlated parameters following specific _ laws. In reports given at recent all-union conferences on labor physiology (15,16), changes occurring in physiological funetions during a work shift which are sometimes diar.~etrically opposed (decrease-increase in pulse, arterial pressure, blood sugar, horm~nes, electrolytes; depression-exaltation of the a-rhythm, and so on) are never- theless interpreted by different authors as signs of approaching fatigue. The reason for this is the rather arbitrary interpretation made of recorded changes, using terms implying "decrement of function" (inhibition, blockade, discoordination, stress, weakening, deterioration and so on), which creates the appearance of an explanatinn of the recorded changes. Broad introduction of polyfunctional recnrding, improvement of the technical side of - experimentation and introduction of computerized mathematical methods for analyzing experimental data have generated the hope that it is mainly along this road-- complicating and refining the data processing methods--that reliable and sufficiently universal criteria of fatigue will be found. However, despite the certain amount of progress that has been enjoyed, this approach has not elevated the problem above empirical inquiry, and it has not led to a qualitative change in diagnosis of fatigue. Assessment of man's state in regard to fatigue symptoms remains within the province of more or less arbitrary interpretation by researchers. 19 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 FOR OFFICIAL USE ONLY The idea that it is impossi.ble to assess fatigue on the basis of some one function, that itsdiagnosis requires an integrated systems approach, is now gaining increasa.ngly greater approval. However, the theoretical side of the question is often limited to too-general, though valid, conclusions appealing for assessment of the state of ~th~ body "as a whole," while practical applications o� the integra~ed approach are reduced to attempts at recording as ~nany functions as possible and subjecting them ; . to summational mathematical treatment without any clear, theoretically grounded hypotheses concerning the principles of integrating differer.t functional signs into a single indicator of fatigue. Thus the main accerrt in the effort to impart psycho- - physiological objectivity to fatigue is laid on.building mathematical models which would "most adequately" synthesize data acquired by numerous measurements. Very great significance is imparted to the search for "the right formula" by which to process the empirical material. . _ While we do not reject the benefits o~ such research, we do not think that we can totally ignore pure psychophysiological research in this area and still come up~with a satisfactory solution to the problem of assessing fatigue. It would be wrong to assume that the field of labor psychophysiology already possesses dependable methods by which to acquire raw data that simply need to be "correctly" processed in order to reveal stable components within the extremely unstable functional pattern of fatigue. There are few studies in the special literature devoted to the psycho- metrics of fatigue in the strict sense of this term (4). Most methods u~ed to diag- nose fatigue reqture standardization and testing for reliability and validity (5). Discussing the physiological mechanisms of fatigue, we should distinguish two groups of phenomena. � On one hand there is the "initial deficit," which arises in the "weakest" link of the functional system and which imparts a certain degree of dissonance to the w~rk of the system as a whole. The question of the functional essence of the initial deficit is at the basis of classical theories of fatigue, and.it was the subject of acute debate during the time of initial development of labor psychophysiology (~2,14). Contemporazy data in physiology and biology support A. A. Ukhtomskiy's conclusion (14) that attempts to formulate a general theory of fatigue based on some universal mechanism of reversible disturbance of a chain of inetabolic reactions are unfounded and unpromising. Depending on the individual psychological qualities of the worker and on the concrete working conditions, to include the entire set of occupational, hygienic, social and psychological factors, the particular location of disturbances will vary, and consequently the concrete physiological signs of the "initial deficit" will be different as well, or at least it would be difficult to reduce them to a limited number of classes. Both the pressing theoretical and practical pr~blems of labor psychophysiology require a meticulous effort to compile a"psychophysiological catalog" of fatigue states. On the other side of the functional pattern of fatigue we observe, concurrently with development of the initial deficit, adaptive alterations in the body aimed at compen- sating for the arising difficulties. A typical example of a nonspecific ~ompensatory.reaction to the environment's counter- homeostatic influence is Selye's general adaptation syndrome, or the stress reaction, which expresses itself primarily in neuroendocrine alterations in the hypophyseo- adrenocortical system (11). Selye included fatigue among a number of factors 2Q FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02109: CIA-RDP82-00850R400440080032-4 FOR OFFiCIAL USE ONLY provoking a stress reaction. The following question naturally arises in this " regard: Can we nAt use the indicators of stress as a universal nonspecific physio- logical sign of fatigue? Practice fails to confirm such a hypothesis. The physio- logical pattern of fatigue may manifest itself within the limits of a broad range of fwactional changes: from typical signs of a stressful state to the typical symptOms ot reduced activation and development of inhibitory proces~es--that is, fatigue cannot be intexpreted as a state which automatically and uniquely elicits the general adaptation syiidrome. Nevertheless some authors (19) feel that "true fatigue," being a consequence of highly motivated labor characterized by stringent effectiveness parameters, is always a general stress reaction. According to this point of view signs of a decrease in activation are more a sign of a reluctance to become tired, than an indication of the depth and degree of fatigue. However, this line of reasoning is far from undebatable, and it does not solve the problem. After all, the "reluctance to become tired" and the decrease in activation ~ ascribed to this state are usually the consequence of work; they are usually a unique protective response to a work load. And there are no grounds for rejecting presence of a relationship between this reaction and fatigue. Clarifying the question as to when and under what conditions a nonspecific compen- satory reaction to fatigue acquires the nature of "negative inhibition" and when it becomes a form of stress (tension) is acquiring fundamentally important significance to general theoretical conceptualizati.on of the fatigue diagnosis problem. Were we to achieve command over these conditions, and were we able to experimentally elicit either the "inhibitory" or the "stressful" manifestation of fatigue, we would have made a significant step forward in our understanding of fatigue, and of the funda- mental 3ifficulties associated with diagnosing this state. The very fact that the Fhysiologicai symptoms of fatigue may be represented by the extreme poles of the scale of activation (inhibition, stress (1)) demonstratively emphasizes these di fficulties. In our opinion the explanation for the instability and uncertainty of functional expression of fatigue by activation parameters lies in the fact that activation level is not an indicator that is uniquely c~etermined by the mechanisms of physiological regulation. But many studies on the psychophysiology of tiring in man implicitly contain the assumption that in a state of fatigue (initial deficit), delicate, intimate changes in int.racellular regulation that cannot be detected directTy by instruments automatically lead to compensatory change in the overall level of arousal of the central nervous system (the level of activation). To reveal the invariant components of this reaction means to find a universal alqorithm of fatigue diagnosis. The fact that despite the technological power of the modern physiological experiment these invariants cannot be revealed elicits fundamental douY~t as to their existence. The fact is that the general physiological pattern of fatigue, in the way that it is represented by activation level indicators, depenas not only and not so much on the magnitude and nature of the initial functional deficit, as on how the individual evaluates the situation in which he finds himself, how he interprets his state and relates it to the objectives of his activity, how he perceives and "overcomes" the unpleasant subjective sensations of fatigue, and so.on. Thus this pattern reflects diverse, variable and whimsical processes associated with man's self-regulation of his state and activity (6). 21 - FOR OFF(CIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 ruK ul~h~LtAL u~~ uNLY R It would hardly be possible to fina a single, clearly delimited fatigue syndrome ~ ~ ' by using, for this purpose, di~gnosis of nonspecific activation parameters. Fatigue ; in the working individual is a state of ambivalent experiences and competing motives: , c?n one hand we have the motives of recovery, self-preservation, reduction of activity, ancl rest, while on the other hand we have the motives of social responsibility and prestige, and maintenance of activity level, often at the cost of additional mobil- ization. And depending on the relationship among these motives, on the nature of the task and the sub-lective significance of the qoals the worker pursues, and on his individual features, a highly variable, "conjunctural" pattern of organization of his activity and functional state evolves. These considerations were the general theoretical background for the experimental study described below. The objective of the eMperiment was to test the hypothesis that the dynamics of some physiological functions proceeding during tiring mental ~ work depend on factors associated w~th psychological self-regulation. , The tentative hypothesis was as follows: "Inhibitory" signs of fatigue (that is, signs indicating a decrease in activation level) would reveal thems~.lves when the meaningfulness and objectives of activity are clearly delimited, and when they do not come into conflict with the natural tendency to reduce activity or with the dominant motives of economization of effort during development of fatigue. On the other hand, the "stressful" signs of fa'cigue (growth in activation level) would manifest ~i~em5elves in situations where the content and meaning of the task facing the subject encourage him to actively mobilize his reaources as the work goes on, in orcler to satisfy the requirements of his activity. Me tho ds The following assignment was chosen as "tiring activity." A series of numbers 1.8 ~ sec apart were played through a tape recorder loudspeaker to a subject in a sound- proof room. The series of numbers was taken from a random numbers table, and it cor~~ained digits from 0 to 9. Somewhere in this series was the letter "z". Its di:;tribution in the series was also random. Z"he minimum interval between two succ:essive letters "z" was three numbers, and the maximum was nine. On hearing the letter "z" the subject had to write down the third number before "z" on a special response sheet (for example on hearing the sequence ...,7, 5, 2, 0, z, 6, 5, 9, 2, 4, 8, z, 3,..., the subject had to write down the numbers 5 and 2). Thus the task was intended to impose a dynamic load on the working memory (this is a"running memory" model). The preliminary experiments showed that 4 hours of continuous work resixlted in intense mental tiring of the subject, who exhibited the typical symptoms of this state (growth in the number of errors, difficulties in concentration, the desire to stop working). Basing ourselves on these data, we interpreted a 4-hour load as a v~olume of work which would "guarantee" development of inental fatigue. The experiments in the main series were performed in two variants. In the first variant the subject worked for a specific length of time. He was told beforehand that the experiment would last 4 hours, and he was able to adapt himself to the temporal dynamics of the experiment. In the second variant the subject worked until "breakdown." The subject had to work diligently until he felt unable to continue the 22 FOR OFFICIAL USE ONLY APPROVED FOR RELEASE: 2007/02/09: CIA-RDP82-00850R000400080032-4 APPROVED FOR RELEASE: 2407102/09: CIA-RDP82-00850R000400480032-4 ~ FOR OFFICIAL USE ONLY work or to maintain the required effectiveness due to extreme fatigue. In this case _ he had the power to stop the experiment. In r2ality, however, the experimenters had no intention of working their subjects to the moment of "breakdown": The experi- m~nt was halted after 4 hours of continuous work (at which time an"equipment failure" was faked). Thus the actual volume of work done in both variants was the same-- 4 hours of continuous performance of the experimental assignment. A typical feature of the psychological atmosphere in which the experiments of the second variant were conducted was that the subjects were unable to accurately estimate the time since the experiment started. All subjects reported intense fatigue after the end of the experiment in both the first and second variant. ~ An EEG was recorded continuously during the experiment with a Hungarian "Orion" eight-channel encephalograph (with a time constant of 0.3 sec and an amplification ratio of 10 mm/50 Uv). Bipolar recordings were made by L. P. Pavlova's technique (10). Wideband filters were used to isolate theta (4-7 Hz) and alpha-rhythms (8-13 Hz) from the total EEG. These rhythms were subjected to integration. The readings of the - integrator were recorded in parallel with the EEG recordings. The data of an EKG, recorded concurrently with the EEG, were used to determine pulse rate. When analyzing the EEG recordings we counted the number of marks made by the inte- grator's stylus each minute. The number of marks was then averaged over a 30-minute interval. The material was subjected to statistical treatment with an"M-222" com- puter, and it included calculation of the arithmetic mean, the standard deviation and the error of the arithmetic mean. Confidence intervals were determined at the 95 percent level of significance (p c6poco Bo~deucmBue (j5) � ~ - ~lq~ Bn~ n edcKa3oNUA 5) , pozpan�rrHOe ycmpo � ynpaDnArowee . l/urcnuvecKU cmBo(ceHppupyemnpe 16) 4oa0e~3cmGue - npu6np onaaueNOe ~npnGnA ~ c6poco~13 eedeucmeueOmev ue npeOcKO~aNUa) ~ Figure 10.

Such df.splays have been found to be an extremely effective means of controlling complex dynamic objects. i~evelopment of prediction displays requires, in particular, an answer to the question as to what is th e optimum prediction time. The choice of prediction time not only determines the requirements to be impospd on technical companents, but it also has a significant influence on the characteristics of human activity. Let us try to calculate optimum prediction time using certain modifications of the general quasi-linear model represented by expression (10), and the calculation scheme proposed by Hollister (41). Let us assume that an individual is included in the control system as shown in Figure 11, and that an ordi~ary compensatory system is used to display the error signal to him. Let us assume Purthermore that the anticipation time Ty contributed by the individual must corre'spond to an optimum prediction timr. (This assumption may be justified with McRuer's "intersecting" model (see Table 3)). At frequencies at which the individual introduces the element of anticipation, the value of the controlling influence u(t) is greater than the ~ error produced by amplification Kpe. At frequencies at which th~ individual intro- duces a time delay, u(t) is less than Kpe. , Let us introduce the anticipation coefficient: L = u8 . .(17).
