Page "learned" Paragraph 479

A suggestion Hypothesis also seems inadequate as an explanation for those who shifted their reactions after they were informed of the possibilities of `` normal '' reactions different from those which they gave.

While they were told that there were some normal people who reacted differently than they had, they were also informed that there were other normals who reacted as they had.

There was no implication made that their initial reaction ( absence of an arm-elevation ) was less preferred than the presence of levitation.

A more tenable explanation for the change in reactions is that the added knowledge and increased familiarity with the total situation made it possible for these subjects to be less guarded and to relax, since any reaction seemed acceptable to the examiner as `` normal ''.
