    Personality influences brain activity patterns, as measured by eye movements. Bidirectional eye movement patterns correlate with better personality adjustment compared to consistent left or right movement.

    Area of Science:

    • Psychology
    • Neuroscience
    • Cognitive Science

    Background:

    • Hemispheric utilization patterns are linked to cognitive processes and personality traits.
    • Conjugate lateral eye movement (CLEM) serves as a non-invasive indicator of brain hemisphere involvement.
    • Understanding the relationship between personality and brain lateralization can offer insights into cognitive styles.

    Purpose of the Study:

    • To investigate the personality determinants of characteristic trends in inferred hemispheric utilization.
    • To explore the correlation between personality variables and patterns of conjugate lateral eye movement (CLEM).
    • To differentiate individuals based on their eye movement patterns (right, left, or bidirectional) using personality assessments.

    Main Methods:

    • Two independent samples (psychology and engineering students) were assessed.

    Related Experiment Videos

  • Conjugate lateral eye movement (CLEM) was used to infer hemispheric involvement.
  • The Adjective Checklist was administered to measure personality and cognitive-style variables.
  • Discriminant analyses were performed to classify subjects based on eye movement patterns and personality scales.

    • Main Results:

    • Discriminant analyses successfully differentiated groups based on eye movement patterns and personality scales.
    • Classification accuracy was 51.9% in the psychology sample and significantly higher at 89.7% in the engineering sample.
    • A bidirectional eye movement pattern was associated with a more adaptive and well-adjusted personality style compared to unidirectional patterns.

    Conclusions:

    • Personality traits are significantly associated with inferred hemispheric utilization patterns, as indicated by CLEM.
    • Bidirectional eye movement is a potential indicator of a more integrated and well-adjusted personality.
    • CLEM analysis, combined with personality assessments, offers a valuable method for understanding brain-behavior relationships.
