    Summary

    Right-eyed, right-handed males showed superior performance on the Vandenberg Mental Rotation Test, utilizing visualization strategies. This study explored the relationship between sensory dominance, handedness, and spatial cognition in undergraduates.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Human Factors

    Background:

    • Individual differences in sensory dominance and handedness are known to influence cognitive abilities.
    • Spatial reasoning, particularly mental rotation, is a key cognitive function with potential links to these individual differences.

    Purpose of the Study:

    • To investigate the relationship between ocular dominance, handedness, and cognitive strategy.
    • To determine how these factors correlate with performance on the Vandenberg Mental Rotation Test.

    Main Methods:

    • 146 undergraduates completed assessments for ocular dominance, handedness, and cognitive strategy.
    • Participants performed the Vandenberg Mental Rotation Test.
    • Performance scores were analyzed in relation to ocular dominance, handedness, and reported cognitive strategies.

    Main Results:

    • Higher spatial scores were observed in right-eyed, right-handed male participants.
    • These groups reported employing cognitive strategies involving less counting and hand use, and more mental visualization.
    • Findings align with and confirm previous research on these relationships.

    Conclusions:

    • Ocular dominance and handedness are significant factors influencing spatial reasoning abilities.
    • Specific cognitive strategies, such as mental imagery, are associated with higher performance in these groups.
    • Results underscore the interplay between sensory-motor biases and higher-order cognitive functions.
