Area of Science:

  • Psychology
  • Sexuality Studies
  • Behavioral Science

Background:

  • Previous research on aggression and sexual orientation in men is inconclusive.
  • Limited empirical evidence exists regarding female sexual orientation and aggression.
  • Aggressiveness and competitiveness are complex traits influenced by multiple factors.

Purpose of the Study:

  • To investigate the relationship between self-reported physical and verbal aggressiveness, interpersonal competitiveness, and sexual orientation in both men and women.
  • To clarify existing mixed findings on aggression and sexual orientation.
  • To explore sex differences in aggression and competitiveness.

Main Methods:

  • Utilized self-report questionnaires to measure physical aggressiveness, verbal aggressiveness, and interpersonal competitiveness.
  • Included participants of diverse sexual orientations (heterosexual and homosexual).
  • Analyzed data to identify significant relationships between variables within and between sexes.

Main Results:

  • Men reported higher levels of both aggression and competitiveness compared to women.
  • Heterosexual men were significantly more physically aggressive than homosexual men.
  • No other significant within-sex differences in aggression or competitiveness were found based on sexual orientation.

Conclusions:

  • Findings support previous research indicating lower physical aggression in homosexual men compared to heterosexual men.
  • The study highlights the complexity of aggression, competitiveness, and sexual orientation, suggesting further research into developmental theories.
  • Results indicate that sex is a primary differentiator for aggression and competitiveness, with sexual orientation playing a more nuanced role.
