Self-concept and brain damage.

C E Vanderhaeghen

    The Journal of General Psychology
    |April 1, 1986
    PubMed
    Summary

    Right-hemisphere brain lesions significantly impair self-concept consistency and differentiation more than left-hemisphere damage. This study highlights the role of brain injury in self-perception and cognitive function.

    Area of Science:

    • Neuroscience
    • Psychology
    • Cognitive Science

    Background:

    • Self-concept is a multifaceted psychological construct.
    • Cerebral lesions can impact cognitive functions and self-perception.
    • Understanding the neural correlates of self-concept is crucial.

    Purpose of the Study:

    • To investigate the differential effects of left versus right hemisphere lesions on self-concept dimensions.
    • To examine consistency of self-report and differentiation width of self-concept descriptions.

    Main Methods:

    • Tested right-handed subjects with unilateral cerebral lesions (left or right hemisphere).
    • Assessed two dimensions of self-concept: consistency of self-report and differentiation width.
    • Analyzed responses to self-descriptive statements to measure consistency and discrimination.

    Main Results:

    • Right-hemisphere injury led to significantly greater adverse effects on self-concept consistency compared to left-hemisphere damage.
    • Differentiation width of self-concept was also more adversely affected by right-hemisphere lesions.
    • Left-hemisphere lesions had a less pronounced impact on these self-concept dimensions.

    Conclusions:

    • Right-hemisphere function is critical for maintaining the consistency and differentiation of self-concept.
    • Psychological constructs can effectively interpret anatomo-clinical data in neuroscience.
    • This research provides insights into the localization of self-concept processing in the brain.
