Final answer:
The Walen and Roth, 1987 sexual interest model focuses on the role of hormones in sexual interest and behavior.
Step-by-step explanation:
The Walen and Roth, 1987 sexual interest model is a theoretical model that focuses on the role of hormones in sexual interest.
According to this model, hormonal influences, particularly testosterone, play a significant role in shaping sexual motivation and behavior.
Testosterone levels have been found to correlate with sexual desire in both men and women, with higher levels of testosterone associated with higher levels of sexual interest.
While the model does not specifically examine the impact of cultural norms on sexual interest, it does provide insights into the biological aspects of sexual motivation.
