| Abstract: | Obtained 11 types of restricted associations and free associations from 24 chronic schizophrenics and 24 normal controls equated for age and education. The associations of schizophrenics were more variable than those of normal Ss, especially on tasks which most restricted the choice of responses. Agreement in responding between normal and schizophrenic Ss was markedly lower when compared with that between high- and low-creative Ss, or with 1-yr, test-retest data. Repetition of responses given to the same stimuli under different instructions was markedly higher for schizophrenic than normal Ss, and thus the degree of task and response differentiation was reduced. The restricted associations overlapped with free associations more markedly for schizophrenic than for normal Ss, but the general structure of a conceptual semantic space was about the same for both groups. It is argued that when explicit constraint in tasks of verbal associations is high, schizophrenic Ss, more than normals, impose a low degree of implicit constraint on their verbal behavior; when the external constraint is low, they increase their implicit constraint.
