Structure of word-storage in permanent memory of young nonpsychotic schizophrenics

Perceptual memory for numerousness in "nonpsychotic schizophrenics."

“…The final question is whether the present findings can be related to the psychopathology of nonpsychotic schizophrenia. In a series of free-recall learning experiments, Koh and his colleagues Koh, Kayton, & Berry, 1973;Koh, Kayton, & Schwarz, 1972) found that nonpsychotic schizophrenics, as compared to normals, were inefficient in "chunking" or unitizing the overloaded verbal inputs into higher level codes. The subjects were judged to be weak in unitizing the affective, semantic, and syntactic features that the experimenter had provided for their mnemonic organization and/or in inventing their own idiosyncratic scheme for unitization.…”

“…The identification procedure adopted in the present study was based on the results of previous research by Koh and his colleagues Koh, Kayton, & Berry, 1973;Koh, Kayton, & Schwarz, 1972), who have been studying modes of information processing in young first-break schizophrenics. These investigators originally selected the subjects for their investigations by means of psychiatric interviews and ratings (Grinker Si Holzman, 1973).…”
