No: But as with correlational research in general, there are alternative explanations ▪ Children who watch more TV in general more violent? ▪ Personality characteristics as a “third variable”? ▪ Parents? Teachers? Environment? Etc.?

What is the relationship between alcohol and aggression? Correlation: 50% of people who commit violent crimes are intoxicated. However:
 •Causal research shows that alcohol INCREASES rather than CAUSES aggression. Factors that DO cause:
provocation, frustrations, cues, biology.

What is alcohols affect on the brain? It is a CNS Depressant (GABA) How?? INHIBITORY EFFECT
Why does alcohol affect aggression? 1. Reduces inhibitions 2.Myopic effects of attention: •“Narrowing” attention to only salient features of situation 
•Most often “narrows” to provoking elements. 3.Decrease in self-awareness: Can’t focus on internal awareness, only on external situation.

What are the basics of interaction in groups? Performance Decision making
Social facilitation Performing better when others are present than when alone.
When Social facilitation occurs: Whether others are performing the same task, or whether the others are merely observers. In many species others than humans
 Ants dig faster in the presence of other ants.
What does being in the presence of others do? The presence of others sometimes enhances and sometimes impairs an individual’s performance.
Social Inhibition Performing more poorly when others are present than when alone. 
 Working as a group. Performing in front of others.
 Executing a task while being observed.
What is the Dominant Respose: Zajonc (1965): - Depends on the task. A task that requires a response that is well learned or innate. What do you really know how to do?
 The presence of OTHERS facilitates performance Complex/Novel/Poorly Learned=decrease in performance with the presence of othe

 Light turned on roaches (they run) 2 Conditions Other roaches watching Nobody watching
Evaluation Apprehension: Concerns about making a good impression on others. If task is complex:
 Pressure of evaluation may be harmful If task is simple:
 Greater effort (not for sure performance)
Facilitation vs. Inhibition: Distraction- Conflict Model: (Baron, 1986) Individual performance can be impaired if the individual focuses on the audience rather than on the task.
Facilitation vs. Inhibition: Distraction- Conflict Model: (Baron, 1986): 2 Basic Tendencies a. To pay attention to the audience b. To pay attention to the task. Easy tasks=little attention→enhancement Difficult task=Heavy attention→audience distracts.
According to Blascovich (1999): what do “others’ activate? 2 distinctive physiological responses: CHALLENGE(enhance task) vs. THREAT (danger)
What happens when participants performing unlearned vs. learned tasks? Unlearned (difficult) tasks in front of an audience showed “Threat” pattern of activation Well-learned (easy) showed a “Challenge” pattern.
What is Social Loafing? • An individuals contribution to a collective activity cannot be evaluated, individuals often work less hard than they would alone. o Social facilitation and inhibition occur when a persons performance is individually identifiable.
What was the study done by Max Ringlemann (1886) on the performance in front of others? Male student volunteers asked to pull as hard as they could on a rope. • 2 gorups: o 7 or 14 Men o Predictions: Larger the group, more force. Results: - Negative correlation between group size and individual effort level.
What does Social loafing depends on? • 1. How important the person believes his/her contribution is to group success o Will you be lost in the crowd? • 2. How much the person values group success o What is the INDIVIDUAL benefit if you have success

What was the study by Latane & Darley (1970): Bystander effect? Fake experiment where an “emergency” occurs next to the lab. IV: Participants Alone Vs. In Group DV: Time to intervene Results: Alone-Help/ Together- Nope
What is the diffusion of responsibility? The presence of other people makes each individual feel less personally responsible.
What was the study on beautiful people? The Beautiful Victims: Good news People more likely to abandon“bystander effect” if victim is attractive.IV: Application left in Phone Booth Ex: Good looking picture •Control: Not Good lookingDV: Mailing the Application Results: Attractive gets mailed
How to reduce social loafing? Make each persons contribution identifiable: oWould you study more if you knew?•Provide rewards for high group productivityoHow many team members “loaf” in the super bowl? •Make task meaningful, complex, or interestingoEliminate any chance to drift…
What is Social compensation? Working especially hard to make up for lazy or incompetent teammates in a task. Occurs when others are performing inadequately, and the person cares about the quality of the group product
Behavior in the Presence of Others in summary: Whether social facilitation or social loafing occurs depends on 3 things? • 1. Whether individuals are identifiable • 2. Task complexity • 3. How much participants care about the outcome on the individual level).
What did Gustave Le Bon (19th century) say about Social Contagion? Its Highly Infectious o When one person does something, even if it would ordinarily be unacceptable to most of the others, everyone else tends to do it also. o Individual values, morals, ethics: GONE.
Whats deindividuation/mob mentality?  Loss of individuality
 Loss of accountability
 Reduction in self awareness
 Act on impulse
 Increased anti-social behavior.
What is Deindividuation? The anonymity of a group can lead people to do things they would not do. o Complete removal of personal identity. o Anonymity is the catalyst to behaviors that are NOT reflective of the individual if they were identifiable.
What was the study on deindividuation done by Diener et al. (1976) (trick or treat)? Stationed themselves in homes during trick-or-treat night.
2 Groups: • ½ children greeted and asked their names. • ½ given candy and not asked name. o Candy left out in front of the house in a very accessible bowl. Results: • Children who gave their names DID NOT EVER STEAL.
What was the study on deindividuation done by Mann (1981) (jumpers)? 21 instances of crowd demographics when someone was threating to jump off a building/bridge. Results: • Smaller crowd/ Daytime= Less “Jumps!” • Larger crowd/ Night= More “Jumps!”
What is the Recipe for De-individuation? •It increases whn individuals are anonymous nd as group size increase•Might create a special psychological state in which people are focused externally and unaware of own values•Heighten individual’s identification with the group and increase conformity.
How to stop deindividuation? Increase peoples self- awareness during group activities. • Large name tags, mirrors, cameras, bright lights and other factors which cause self-focus.
What is the relationship between competition and cooperation? Participants in lab studies on competition tend to compete, even when cooperation would be a more rewarding strategy.
How to study competition vs. Cooperation? Game Theory: • Method of studying decision making in situations of conflict and cooperation.
Whats the prisoners dilemma? Common Result: • Competition even when cooperation would lead to greater reward.
What is Gametheory? o Study of strategic decision making. o The study of mathematical models of conflict and cooperation between intelligent
What is the Road Map of the Trucking Game Krauss? You need to figure out how to make you get their quicker and people usually chose route which involved no cooperation.
What was the results of the: Road Map of the Trucking Game Krauss? Optimal Strategy: • Cooperation-Alternate use of gates Adopted Strategy:
 - Conflict at gates
 - Refusal to ‘retreat’
 - If retreat—Close their gate after -Take the long road to avoid conflict
Whats the prisoners dilemma game and goal and limits? Prisoners dilemma: Goal: Get the most $$ (for you) Limitations: NO communication
What is the Zero-Sum Game? • One person’s gain is another’s loss • Ex: poker Non-Zero-Sum Game • Pick a card…
What is nature vs. nurture result on Zero-Sum Game? NATURE? • Zero-Sum Nurture (social)? • -Non-Zero-Sum
Whats the prisoners dilemma (real life sit)? You and friend committed crime: DA knows but cant quite prove it.You-friend are in diff rooms.2 Alternatives:•A. Confess (You get lesser crime/ buddy fries)•B. Don’t confess (Neither get caught)Results: 1/3 of choices are cooperative. 2/3 are Competitive.
Determinants of Competition vs Cooperation Reward Structure • Is one persons gain anothers loss? • What happens when congress vetoes a bill Personal Values • Cooperator or Competitor? Independent/ Interdependent? Communication • Communication changes outcomes in both games.
Culture and Competition The United States has one of the most competitive cultures on earth. Home, at school, through the media, and through sports and games. USA:1/10-cooperation
 Mexican:7/10-Cooperation (got more)
