As discussed previously, social roles are defined by a culture’s shared knowledge of what is expected behavior of an individual in a specific role. This shared knowledge comes from social norms. A social norm is a group’s expectation of what is appropriate and acceptable behavior for its members—how they are supposed to behave and think (Deutsch & Gerard, 1955; Berkowitz, 2004). How are we expected to act? What are we expected to talk about? What are we expected to wear? In our discussion of social roles we noted that colleges have social norms for students’ behavior in the role of student and workplaces have social norms for employees’ behaviors in the role of employee. Social norms are everywhere including in families, gangs, and on social media outlets. What are some social norms on Instagram? Connect the Concepts Tweens, Teens, and Social Norms My 11-year-old daughter, Janelle, recently told me she needed shorts and shirts for the summer, and that she wanted me to take her to a store at the mall that is popular with preteens and teens to buy them. I have noticed that many girls have clothes from that store, so I tried teasing her. I said, “All the shirts say ‘Aero’ on the front. If you are wearing a shirt like that and you have a substitute teacher, and the other girls are all wearing that type of shirt, won’t the substitute teacher think you are all named ‘Aero’?” My daughter replied, in typical 11-year-old fashion, “Mom, you are not funny. Can we please go shopping?” I tried a different tactic. I asked Janelle if having clothing from that particular store will make her popular. She replied, “No, it will not make me popular. It is what the popular kids wear. It will make me feel happier.” How can a label or name brand make someone feel happier? Think back to what you’ve learned about lifespan development. What is it about pre-teens and young teens that make them want to fit in (Figure 12.9)? Does this change over time? Think back to your high school experience, or look around your college campus. What is the main name brand clothing you see? What messages do we get from the media about how to fit in?
