The place of cooperation in the examination of mental disorder.

The problem of cooperation is addressed here in relation to the possible invalidation of experimental and psychometric results produced by either a lack of effort or inability, on the part of subjects, to give the necessary attention to make a sampling of psychological function a fair one. The author draws on findings from a group of psychological tests and experiments conducted at the Worcester State Hospital on schizophrenic and other subjects. A rating system for evaluation cooperation level used at Worcester is discussed, as is the complexity of the cooperation problem. Results are considered in terms of: a) the distribution of cooperation an representativeness among the various psychoses and normal subjects examined; b) correlation of cooperation and representativeness with performance; and c) change in score with change in cooperation on selected tasks where the tests were repeated. Correlations of score and cooperation reached modal levels of .60, and changes in score were generally correlated with cooperation.

Kent-Rosanoff Association and its implications for segmental set theory.

Data about numerous repeated administrations of the Kent-Rosanoff Association Test to schizophrenic subjects not found elsewhere in the literature are presented. A quantitative scoring system, in the form of a Composite Index, is also provided. And lastly, association results offer further evidence for the theory of segmental set. Data are provided on the responses of 60 schizophrenic patients and 60 normal subjects (college and noncollege) on two repetitions of the test, and five repetition for schizophrenics. Results of the comparison between schizophrenics and normals indicate that schizophrenics give fewer most common, more individual, and more unusual responses; have a higher Composite Index; have a lower percentage of responses given in identical form; and show less learning ability on test repetition. As between paranoids and hebephrenics, paranoids have higher repetition scores, and given more most common, more individual, and fewer unusual responses. These results reflect clinical condition and are viewed as corroborating the segmental set hypothesis.

The "Guinea Pig" Formboard: its construction and some learning norms.

A formboard test was presented to 51 male (age 20-45) and 47 female (age 18-36) Ss having a college level education. The test attempted to follow a definite principle of construction in the six figures which comprise it. Each S was presented with a set of randomly arranged blocks and asked to put them where they belonged as quickly as possible. Three successively timed trials were given. Results indicate no significant sex differences in mean time on any of the trials; a trial-to-trail improvement that is almost identical for males and females; and virtually no differences when reversals of the first order in succeeding trials over previous trials are considered. The author suggests that the task offers promise for further study of the qualitative nature of formboard response and merits standardization on a group through various age levels.
