1. All research involving human participants must be approved by what’s called an institutional review board (IRB) or other committee that reviews the ethics of research studies. In this example, a research study in which participants would be allowed to hit each other probably would not be approved by such a committee.

2. There are of course many ways to divide a 12-item scale into halves (e.g., even- and odd-numbered items or first six items and last six items). Typically, researchers use computer software, such as the program we will begin learning later in this chapter, to assess internal reliability. We’ll discuss more about internal reliability in Chapter 12.

3. In case you are interested in Terrell et al.’s (2008) results, they found that men who were more narcissistic gave more noise blasts (that is, acted more aggressively) than men who were less narcissistic. Women did not differ in their aggressive behavior based on their level of narcissism. In addition, women with a tendency to act aggressively were more likely to display aggression against a low-status competitor, whereas males with a tendency to act aggressively were more likely to display aggression against a high-status competitor.
