Subject:. SI Testing, 17 July 1951, (Polygraph Room #3).

On 17 July 1951, between 6-9:00 PM, conducted.SL.and H experiments and tests with the following subjects: and

Since in habsence had continued the SI and H experiments, there was no necessity for basic "relaxing" techniques and all subjects responded with great rapidity (5-20 seconds) to induction to trance. All subjects were given many simple control, amnesia, and dépth tests which indicated subjects were ready for more ädvanced experimentation.

The advanced experiments were then started using each subject in rotation while others observed--all subjects having been briefed in advance. These tests were designed to determine whether or not average individuals under H control could move, talk, and think in a completely"normal" manner if so instructed.

In each case, were able to produce the desired result or such a close approach to "normal" activity that tests were regarded as completely successful. However, it should be noted that the ability to act normally apparently varies in each suhject--one having a slowness of movement, one a temporary lack of ave control, and allhaving slightly changed speech activity. and at this point are of the opinion that by careful instructions to the subject to act normally in all ways, even these minor variations in normal" behavior could be removed. Tests were concluded with the usual precautionary instructions.

Comment:

Above subjects apparently are capable of excellent performances and an agreed that with same further work, any of the above could fool any but the most careful observers in normal activity.
