On 17 July 1951, between 6-9:00 Pr4i conducteg",Ind_H test.,3 Su jpcts: Since i senc- 2 ad continued the SI and H exper men s, re was no n ty for basic "relaxinp, techniques and all subjects responded with great rapidity (5-20 seconcis) to induction to trance. All subjects were given many simple control, amnesia, and ddpth tests wfiicti indicated subjects were ready for more 'gdvan'ced experimentation. 2 The advanced experiments were then started using each subject in rotation while others observed--all subjects liav-Lng been briefed in advance. These tests were designed to determine whether or not average indiv-iduals under 11 control could move, talk, and think in a completely "normal" manner if so instructed. In each case, ere abll-- to procluce the desired result wor su e approac 0 normal" activity that tests were regarded as completely successful. Howp-vcr, it should be noted that the ability to act normally apparently varies in each subject--one having a slowness of movetent, one a tempo- rary lack ol a l@ ving slightly chanqed2 speech activity. at this point are of the opinion th by care s 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 in- structions. 2 efI Comment: Above subjects apparentl are le of excellent es an agreed that performanc, with same further could fool any w but the most careful observers in normal activity. 3 II Ik 4
