Chapter 19 Part 3
I. Aggression and Violence • Our interpretation of what is going on around us influences how we respond to each situation. Exposure to violent media can increase a person’s hostility when responding to events. • Culture can have a large effect on aggression. Some cultures are less aggressive than others, often because the whole is more important than the individual.
I. Aggression and Violence • Men tend to be more aggressive than women partly because of hormones, partly because that is the expectation of male social activities. • Group dynamics also play a part in aggression. When people are in groups, deindividuation occurs. We lose our sense of responsibility for our actions and follow what the group is doing. • We also feel bolder to take risks in groups, because there is less accountability for what we do. This is called the risky shift phenomenon.
I. Aggression and Violence • Biology does play an important part in aggression. The hypothalamus controls the primal emotions like anger, pleasure, hunger and others. • Allergies can affect brain function just like drugs and alcohol do. They call can change the chemistry in the brain so that either more or less of certain neurotransmitters are produced.
I. Aggression and Violence • Violent movies, TV shows, and video games have all been accused of causing violent behaviors in those that watch or play them. • There also seems to be an increase in violent behavior or tendencies is the violence that is watched is justified. If a bad person is shown as getting punished, they are “getting what they deserve” and that is okay.
I. Aggression and Violence • Imitation learning is the idea that we mimic what we see. If we see violent acts, those will be copied. If we see positive acts, those will also be copied. • Violence witnessed in real life has even more traumatic effects. PTSD is not just for soldiers coming back from war. People that are subjected to or witnessed violent acts have the same reactions as soldiers because they are seeing the same things.
