    This study found that masculine sex-role orientation negatively impacts spatial ability performance, challenging traditional hypotheses. Electrocortical measures revealed distinct frontal and parietal brain activity patterns related to sex roles and spatial tasks.

    Area of Science:

    • Cognitive Neuroscience
    • Psychology
    • Neuroscience

    Background:

    • Investigating the interplay between psychological constructs like sex role orientation and cognitive abilities such as spatial processing is crucial for understanding human cognition.
    • Previous research often focused on biological sex differences in spatial ability, potentially overlooking the influence of gender roles and their neurophysiological underpinnings.

    Purpose of the Study:

    • To explore the relationship between sex role orientation and spatial ability.
    • To differentiate the roles of frontal and parietal electrocortical (EEG) measures in relation to sex role and spatial task performance.
    • To challenge traditional hypotheses regarding sex and spatial abilities by examining sex role influences.

    Main Methods:

    • Administered the Differential Aptitudes Space Relations Test and the Personal Attributes Questionnaire (PAQ) to 254 subjects to assess spatial ability and sex role orientation.

  • Selected 40 male and female participants based on sex role scores for further testing.
  • Recorded bilateral electroencephalogram (EEG) from frontal and parietal areas during visuo-spatial problem-solving tasks.

    • Main Results:

    • Frontal EEG measures correlated with participants' sex role orientation.
    • Parietal EEG measures were associated with visuo-spatial task performance in males, but not in females.
    • Spatial task performance showed a negative correlation with masculine sex-role orientation.

    Conclusions:

    • Frontal and parietal EEG measures appear to reflect distinct neurophysiological processes.
    • Spatial processing is influenced by factors beyond biological sex, including sex role orientation.
    • Findings suggest a complex relationship between gender roles, brain activity, and spatial cognition, necessitating a nuanced approach to understanding these differences.
