[The psychological reasons for the varying efficacy of suggestion in an experiment].

In 86 neurotic patients, judgements about TAT pictures were defined before a session of hypnosis. Later other judgments about the same pictures were suggested after the patients entered the hypnotic state. 34 patients who were in a deep enough hypnotic state manifested the lack of suggestion realization, which can be accounted for by image and intellectual activity that occurred at the moment of suggestion. Suggestibility increased whatever the depth of the hypnotic state, on condition that at the moment of suggestion the image and intellectual perception of TAT pictures could be rearranged. The given study made it possible to explain the occasionally occurring difference in suggestibility and hypnability which is of practical value.
