title: Catalepsy tests: what do they tell us?
abstract: In a survey of 200 clinicians regarding their use of catalepsy tests, three fourths of the respondents indicated that they used these tests. In light of this response, and considering both the scientific importance of being able to identify the presence of hypnosis and the fact that catalepsy may account for up to eight of the other indications of hypnosis in use, it is relevant to inquire into the reliability and validity of catalepsy tests. It was found that of the three tests of catalepsy currently in use, only one has the potential for being a test of hypnosis proper and can also justifiably be said to be "of catalepsy." This one test, however, has many serious weaknesses that need to be eliminated if it is to be truly useful.
