Group
A collection of people who interact and share a common identity or goal

Four conditions of contact hypothesis
Equal status between groups, common goals, intergroup cooperation, and support from authorities, laws, or social institutions
Aggression and biochemistry
Neurotransmitters and hormones influence aggression by affecting emotional reactivity, impulse control, and responses to threats
Testosterone
A hormone associated with dominance and status-seeking that may be related to aggression in some contexts, but does not directly or inevitably cause aggressive behavior
Serotonin
A neurotransmitter involved in mood and impulse regulation. Lower serotonin functioning has been associated with increased impulsive aggression
Alcohol
Alcohol can reduce self-control, narrow attention to immediate cues, and increase aggression in situations involving provocation
Frustration
An obstacle that prevents someone from reaching a goal or obtaining something desired
Frustration-aggression theory

Social learning theory
The theory that aggression can be learned by observing others, imitating their behavior, and experiencing rewards or consequences

Aggression as a reward
Aggression can be reinforced when it produces desired outcomes, such as gaining resources, status, control, or compliance
Influences on aggression
Aversive experiences, frustration, heat, pain, arousal, aggressive cues, media exposure, alcohol, and group settings can increase aggression
Two-factor theory of emotion
The theory that emotion involves physiological arousal and a cognitive label explaining that arousal
Excitation transfer
Arousal from one situation can carry over into another situation and intensify an emotional reaction, including anger and aggression
Media influences on aggression
Exposure to violent media can increase aggressive thoughts, feelings, and behavior by modeling aggression, desensitizing viewers, and teaching aggressive scripts
Correlational evidence
Evidence showing that exposure to violent media is associated with aggression, but correlation alone cannot establish that media exposure causes aggression
Experimental evidence
Studies that manipulate media exposure and measure subsequent behavior can support causal conclusions about short-term effects, although laboratory aggression measures have limitations
Social scripts
Learned mental guidelines for how to behave in particular situations. Violent media can teach scripts that make aggressive responses seem appropriate
Guns as cues of aggression
The weapons effect: the presence of a gun or other weapon can increase aggressive thoughts or behavior by activating aggression-related associations
How to reduce aggression
Reduce provocation and aggressive cues, teach nonviolent conflict resolution, model prosocial behavior, reinforce cooperation, regulate violent media exposure, and promote empathy
Group
Two or more people who interact together and may develop an us-versus-them mentality
Minimal groups
People categorized into groups based on trivial distinctions, such as early versus late arrivals or birth months
Social facilitation
The strengthening of dominant responses in the presence of others. Arousal improves performance on easy or well-practiced tasks but hinders performance on new or difficult tasks
Evaluation apprehension
Concern about how other people are evaluating or judging us
Driven to distraction
The presence of an audience creates competing demands for attention, potentially causing cognitive overload and impairing performance
Mere presence theory

Reducing social loafing
People loaf less when tasks are appealing or meaningful, challenging, incentivized, or completed with friends or cohesive group members

Factors contributing to deindividuation
Group size, anonymity, and distracting experiences such as loud noises or chanting
Group polarization
The tendency for group discussion to strengthen people's initial opinions, causing group members to adopt more extreme positions
Informational reasons for group polarization
People focus on arguments supporting their side, learn new arguments from others, and rehearse or repeat supporting ideas during discussion
Normative reasons for group polarization
People compare their opinions with others in their group and adjust their beliefs to fit in or gain approval, creating a bandwagon effect
Group polarization in communities
Increased mobility allows people to self-segregate among like-minded individuals, reinforcing existing opinions and increasing polarization
