Sexual-perception processes in acquaintance-targeted sexual aggression.

Area of Science:

• Psychology
• Forensic Psychology
• Social Psychology

Background:

• Misperception of women's sexual interest (MSI) is a potential risk factor for sexual aggression.
• Previous research has primarily relied on self-report measures, which may be subject to biases.

Purpose of the Study:

• To examine the association between performance-based indices of men's MSI and factors such as sexual-aggression history and rape-supportive attitudes.
• To investigate the relationship between these MSI indices and other relevant variables including sociosexuality, problem drinking, and self-reported MSI.

Main Methods:

• Analysis of data from seven published studies involving nearly 2000 undergraduate men.
• Utilized the Heterosocial Perception Survey-Revised to assess men's judgments of the justifiability of unwanted advances.
• Employed a non-linear mixed-effects framework with a three-parameter logistic function to estimate participant-specific sexual-perception processes (baseline justifiability, bias, and sensitivity).

Main Results:

• Sexual-aggression history and rape-supportive attitudes were significantly associated with reduced sensitivity to women's affect.
• These factors also predicted more liberal biases in perception and greater baseline justifiability of continued advances.
• Sexual-aggression history and attitudes correlated more strongly with perceptual sensitivity than baseline justifiability.

Conclusions:

• Performance-based measures of sexual perception processes offer valuable insights into the psychological underpinnings of sexual aggression.
• Findings underscore the critical role of sexual-perception processes, particularly sensitivity and bias, in understanding and potentially preventing sexual aggression.
• The study demonstrates the utility of deriving performance-based estimates of sexual perception from questionnaire responses.
