“…These data contrasted with earlier research (Shimkunas et al, 1966) which had shown that abstract and concrete interpretations of proverbs were highly related to intelligence and only minimally related to measures of psychopathology, and did not change as the patients improved clinically. The development of the autistic response category (Shimkunas et al, 1967) thereby provided a means for critically evaluating some of the problems inherent in Goldstein's conceptualization of schizophrenic psychopathology.…”

“…Other investigators also have found moderate to strong inverse relationships between verbal intellectual ability and concreteness, but these studies did not assess more specific neurocognitive deficits (Hertler et al, 1978;Shimkunas et al, 1966). In contrast to the varying results for idiosyncratic and concrete thinking, a moderate to strong positive relationship has consistently been found between correct abstraction on proverbs and intellectual ability (Carpenter and Chapman, 1982;Harrow et al, 1974;Shimkunas et al, 1966). These studies were limited to the assessment of intellectual ability, and to our knowledge, associations with more specific neurocognitive abilities have not been examined.…”

“…In contrast, Sponheim et al (2003) reported that 59% of the variance in concreteness could be explained by estimated intellectual ability and impairment in complex attention, visual memory, and planning. Other investigators also have found moderate to strong inverse relationships between verbal intellectual ability and concreteness, but these studies did not assess more specific neurocognitive deficits (Hertler et al, 1978;Shimkunas et al, 1966).

Neurocognitive and social cognitive correlates of formal thought disorder in schizophrenia patients

The neurocognitive and social cognitive correlates of two types of formal thought disorder (i.e., bizarre-idiosyncratic and concrete thinking) were examined in 47 stable outpatients with schizophrenia. Both types of thinking disturbance were related to impairments in verbal learning, intrusions in verbal memory, immediate auditory memory, sustained attention, and social schema knowledge. Distractibility during an immediate memory task was associated with more frequent bizarre verbalizations but not concreteness. Impaired verbal learning rate and intrusions in verbal memory independently contributed to the prediction of bizarre responses, whereas intrusions in verbal memory and impaired immediate memory independently contributed to concrete thinking. This pattern of findings is consistent with the view that neurocognitive and, possibly, social cognitive deficits underlie these two aspects of formal thinking disturbance in schizophrenia. D

“…The value of the so-called proverbs test has been strenuously debated and (Payne & Hewlitt: 1960) suggested that if schizophrenics were given enough time they could produce abstract interpretations of proverbs in a similar way to normals. (Shimkunas et al 1966) felt that the ability to abstract is so strongly associated with I.Q. that little can be deduced.…”
