| dc.description.abstract | Bauman and Murray (1968) and Nachmani and Cohen ( 1969) have shown that schizophrenics perform as well as normals and non-schizophrenic psychiatric patients on simple recognition tasks, but have poorer performance on recall tasks. A study by Bannatyne (1971), using paired-associate recognition and recall analogues, found that schizophrenics were inferior to normals on both tasks. Bannatyne concluded that two factors could be operating to produce decrements in the schizophrenics’ performance ( i) poor utilization of stimulus cues for the formation of associative bonds, and (ii) overloading at input due to abnormally slow processing. This thesis investigates the proposition that schizophrenics are inefficient in their utilization of associations between words as cues for organizing verbal material. Simple recognition tests of material of varying levels of association were administered to 16 schizophrenic and 16 normal subjects. Results show equivalent performance for the two groups on a low association task and superior performance for normals over schizophrenics on a high association recognition task. These are interpreted as supporting the initial hypothesis that schizophrenics are inefficient in their utilization of associations as organizational cues. However, it is felt that the possibility of retrieval factors contributing to the schizophrenics' poorer performance cannot be completely excluded. | en |
