Big 5 Model of Personality
As discussed in Chapter 3, the term personality refers to a relatively stable set of characteristics,
temperaments, and tendencies that shape the similarities and differences in people’s behavior.

Type A Behavior Pattern

discovered what they called the Type A behavior pattern. They searched the medical literature
and found that traditional coronary risk factors such as dietary cholesterol, blood pressure, and
