Final answer:
Zhou's findings on brain sex theory have been supported by studies on patterns of brain activation during sexual arousal, frequency of sexual cognitions, and human mate preferences.
Step-by-step explanation:
Zhou's findings on brain sex theory have been supported by several studies that have examined patterns of brain activation during sexually evoked arousal in different groups of individuals. For example, a study by Hu et al. (2008) found that patterns of brain activation differed between homosexual and heterosexual men, suggesting divergent neural responses to sexual stimuli. Another study by Fisher et al. (2011) explored the frequency of sexual cognitions as a function of gender, eroto_philia, and social desirability, providing further evidence for the relevance of brain sex theory. Additionally, research on human mate preferences by Buss (1989) has also contributed to supporting the theory.
