1. Whatever the relative roles played by biological and environmental factors may be, most investigators believe that a person’s sexual orientation is not a matter of choice. Why do you think so many people consider sexual orientation to be a moral issue?
2. As you saw, both male sexual behavior and maternal behavior are disrupted by lesions of the medial preoptic area; thus, the MPA performs some functions necessary for both behaviors. Do you think that the functions are common to both categories of behavior, or do you think that different functions are involved? If you think the former possibility is true, what might these functions be? Can you think of any common features of male sexual behavior and maternal behavior?
