Goal-directed thinking in schizophrenics' associations.

M L Silverstein, M Harrow

    Journal of Personality Assessment
    |April 1, 1983
    PubMed
    Summary

    Neither the chaining nor continuity hypothesis explained cognitive disorganization in schizophrenia. Both schizophrenic and non-schizophrenic individuals maintained associative structure, though both showed response disorganization.

    Area of Science:

    • Cognitive psychology
    • Psychopathology
    • Neuroscience

    Background:

    • Schizophrenia is associated with disorganized thinking.
    • Previous theories proposed associative structure derailment or meaning disorganization.

    Purpose of the Study:

    • To investigate the relationship between associative structure and higher-order cognition in schizophrenia.
    • To test the chaining and continuity hypotheses.

    Main Methods:

    • Continuous word association technique was used.
    • Participants included individuals with schizophrenia and non-schizophrenic controls.
    • Schizophrenic subgroups were analyzed based on paranoid status and premorbid adjustment.

    Main Results:

    • Neither the chaining nor continuity hypothesis was supported.
    • Both schizophrenic and non-schizophrenic groups maintained guiding responses.
    • Both groups exhibited progressive response disorganization.
    • No differential performance was found between schizophrenic subgroups.

    Conclusions:

    • Existing hypotheses on associative structure in schizophrenia require revision.
    • Response disorganization occurs in schizophrenia independently of the tested hypotheses.
    • Associative structure maintenance is preserved in schizophrenia despite cognitive deficits.
