Research on the Serotonin Transporter Gene, Described in Your Textbook

Essay

Research on the serotonin transporter gene, described in your textbook, offers a good example of a moderator effect - when the implications of one variable depend on one's level of some other variable. In this case, the effects of having vs. long serotonin transporter genes (or one of each) appears to moderate the effects of one's environment. Summarize the nature of this effect, and give one example of a specific research study, described in your textbook, that illustrates this moderating effect.
