A Sex Difference in the Specificity of Sexual Arousal +
How is genital arousal measured in men?
Genital arousal in men is measured using penile plethysmography. This involves placing a device around the penis to assess changes in size and circumference, providing an objective measure of arousal.
How is genital arousal measured in women?
Genital arousal in women is measured using vaginal pulse amplitude (VPA) via vaginal photoplethysmography. This technique assesses changes in blood flow to the vaginal walls, indicating physiological arousal.
What is category-specific sexual arousal?
Category-specific sexual arousal refers to the phenomenon where individuals show heightened arousal to stimuli depicting their preferred gender or sexual activity. It implies a specific pattern of arousal based on one's sexual preferences.
How do the sexes differ in terms of category-specific genital arousal?
Men typically exhibit category-specific genital arousal, responding more strongly to stimuli corresponding to their preferred gender. In contrast, women often show less category specificity, with arousal to stimuli depicting both genders.
How do heterosexual men and women differ in terms of the sexual stimuli they find the most subjectively arousing?
Heterosexual men often find stimuli depicting their preferred gender most subjectively arousing. In contrast, heterosexual women may show a less consistent pattern, with subjective arousal not strongly tied to self-reported preferences.
How do gynephilic and androphilic men differ in terms of genital arousal? How are they similar?
Gynephilic men (attracted to women) typically show genital arousal to female stimuli, while androphilic men (attracted to men) exhibit arousal to male stimuli. They differ in their preferred gender for arousal but may show similarity in the strength of arousal within their preferred category.
Are gay men’s patterns of genital arousal feminized?
No, gay men's patterns of genital arousal are not feminized. They typically show category-specific arousal, responding more to stimuli depicting their preferred gender (male), consistent with their sexual orientation.
Why do Chivers et al. (2004) state that “sexual arousal, especially genital sexual arousal, likely plays a much smaller role in women’s sexual orientation development than it does in men’s”?
Chivers et al. suggest that sexual arousal, particularly genital arousal, may play a smaller role in women's sexual orientation development compared to men. This could be due to the observed nonspecific patterns in female arousal, indicating that women's sexual orientation may be influenced more by extrinsic factors than intrinsic ones like genital arousal.
