Comparison of two methods of administering the Halstead Category Test.

Developed an alternative method of administering Halstead's Category Test that uses answer sheet and latent image developer. The method does not entail bulky apparatus operated by the examiner. There is lessened possibility of examiner error in providing reinforcement and in recording responses. Use of visual rather than auditory reinforcement makes the method useful with the deaf. Performance on alternative and standard methods by psychiatric inpatients (N = 50) was the same, which suggests that the two methods are equivalent.
