[Group experiment to investigate judgement-convergence and the assessment of reality in schizophrenics presented with...

Eight acute schizophrenics were examined individually and in groups as to their congruence of judgement and as to their accuracy in estimations in response to various visual stimuli; they were compared in these respects with neurotics. The analysis of variance of the power of judgement showed: (a) there was no difference in the two groups of patients beyond what could be expected by chance alone, and (b) the congruence of judgement was the same in both groups. The analysis of variance of the accuracy in estimations showed that with increasing numbers of stimuli in the visual field the schizophrenics became less and less precise in their estimates. It was demonstrated under what conditions social-psychological findings can be applied to schizophrenic psychoses.
