Subject: SI and H Experimentation, 16 June 1953
)03
In view of the fact that these subjects had worked for a considerable
period of time and had reached a levelling off stage in which it appears
that their interest is no longer as strong as it had been at the start
of the work, it was decided to show them the various movies taken and have
a discussion on the_.film.According1y, the film was shown and work was
commented upon
At the conclusion of the movies, a straight induction test was run on
all hands followed by simple PH carried on by the various operators present.
In view of the fact that there were present six subjects and four operators,
this work was kept quite simple and was carried out primarily to sustain
interest. No advance work was undertaken and the PH were of a standard
variety with nothing complex attempted.
The work was concluded at 9:05 PVI.
