Construct validity of the Weigl Color-Form Sorting Test

A S Tamkin, J T Kunce

    Perceptual and Motor Skills

    Summary

    This study found that difficulty shifting cognitive sets on the Weigl Color-Form Sorting Test correlates with signs of cortical dysfunction in psychiatric patients. This suggests the Weigl test may help assess symbolic reasoning deficits related to brain impairment.

    Area of Science:

    • Neuropsychology
    • Cognitive Psychology
    • Psychiatry

    Background:

    • Cortical dysfunction is associated with various cognitive impairments.
    • The ability to shift conceptual sets is a key cognitive function.
    • Previous research suggests links between specific tests and cortical dysfunction.

    Purpose of the Study:

    • To replicate previous findings on the Weigl Color-Form Sorting Test and cortical dysfunction.
    • To investigate the relationship between the Weigl test and other neuropsychological measures.
    • To determine if the Weigl test can assess symbolic reasoning deficits.

    Main Methods:

    • The study involved 38 male psychiatric inpatients.
    • The Weigl Color-Form Sorting Test was administered.
    • Correlations were examined with Bender-Gestalt recall, WAIS Similarities, WAIS Verbal IQ, age, Hooper Visual Organization Test, and Trail Making Test.

    Main Results:

    • Inability to "shift" on the Weigl test correlated with indices of cortical dysfunction (Bender-Gestalt, WAIS Similarities, age).
    • A regression analysis showed ability to shift was predictable from the difference between WAIS Verbal IQ and age (multiple R = .52).
    • The Weigl test showed a near-significant relationship with the Hooper test but not the Trail Making Test.

    Conclusions:

    • The Weigl Color-Form Sorting Test's "inability to shift" measure is consistent with cortical dysfunction.
    • The Weigl test may serve as a non-verbal tool to assess cortical dysfunction.
    • Deficits in shifting appear to reflect a dysfunction in symbolic rather than spatial reasoning.
