I OBJECTIVE
The object of this document is to provide an interim technical report on tasks 6.2 "Basic Research," 6.3
"Applied Res;earch," and 6.4 "Research Methodology" as listed in the 1991 Statement of Work. This
report covers the time period from 4 February 1991 to 31 December 1991, and includes all subtasks.*

II INTRODUCTION
Under Statement of Work items 6.2, 6.3, and 6.4 in contract MDA90$-91-C-0037, the Cognitive
Sciences Laboratory of Science Applications International Corporation is tasked to conduct pheno-
menological research and analysis.
This document details the activity accomplished under these items and constitutes the interim report
covering the period from 4 February to 31 December 1991.

III PROGRESS TO DATE
This section describes the progress to date for each of the sub-tasks listed under items 6.2, 6.3, and 6.4 (basic
and applied research and research methodology, respectively). The section numbering corresponds to the
numbering in the Statement of Work.
6.2 Basic Research
6.2.1 Magnetoencephalography (MEG) Investigations
From 8 through 22 September 1991, the first of a three-part MEG investigation was carried out using
receivers from a variety of populations. Details of the protocol maybe found in a separate document,
which has been approved by the Scientific Oversight Committee (SOC).1* It is beyond the scope of this
report to describe the protocol in detail; however, we provide a brief overview here.
Each of twelve receivers contributes ten blocks of data. Each block consists of ten two-minute runs each
of which contain approximately 100 remote and 100 pseudo stimuli. Each block of data is accompanied
by a control block of equal length during which the conditions are identical to the experimental block;
however, no receiver is present under the MEG. The dependent variable is the average effect size of the
RMS relative phase shift (i.e., prestimulus to poststimulus) of the dominant alpha rhythm.
Table 1 shows the results in the experimental condition for the first six receivers. The shaded receiver
number indicates those that were specified a priori as being among the formal participants. The average
effect size, the total number of stimuli and the p-value, which was determined by Monte Carlo tech-
niques, are shown as e, N, and p, respectively. The differences between the remote and pseudo stimuli
are shown as t-scores with df degrees of freedom and an associated p-value of p.
