Groups can be: (3)
- large or small
- short-lived or enduring

Stanford Prison Study
- originally supposed to be a 2 week study, shut down after 5-6 days
- male Stanford students paid to be either guards or prisoners in a mock prison set up in the basement of a university building
- guards became very abusive and sadistic

causal relationship

more cohesiveness = better performance

better performance = more cohesiveness
Social Facilitation
the tendency for people to do better on simple tasks, but worse on complex tasks, when they are in the presence of other people and their individual tasks/performances can be evaluated
Norman Triplett's Social Facilitation Experiment (1897)
hypothesis: people perform better in front of others that alone

- cyclists racing
- kids winding up a fishing rod

conflicting research results post-Triplett (sometimes enhance, sometimes impair)
Robert Zajonc's (pronounced Zions) Social Facilitation Hypothesis
arousal is key
Why does the presence of others cause arousal? (3)
- causes us to be particularly alert/vigilant
- makes us apprehensive about how we're being evaluated/judged
- distracts us from the task at hand

Who has to over-train to be able to bypass social impairments?
- firefighters
- police

- if you're learning how to play the violin or a new piece, having an audience will impair your performance
Cockroach Study
- timed how long it took cockroaches to run from one side of a maze to another
- easy maze (straight line) = go faster with "spectator" cockroaches present
- hard maze (right turn) = go slower with "spectator" cockroaches present
Mere Presence Theory
the simple presence of others will enhance the performance in speed and accuracy in easy tasks, but will impair performance in difficult tasks
Evaluation Apprehension Theory
the presence of others makes us concerned over what they will think of us, which can either enhance or impair our performance
Distraction Conflict Theory
attention conflict between focusing on the task and inspecting the distracting stimulus creates arousal
Blindfolded Confederates Study
- pairs to perform tasks in front of each other

Blindfold Rope Test
- participants blindfolded and put on a rope pulling machine (can test the force exerted)
- 2 conditions:
1 - told they were pulling alone
2 - told they were pulling as part of a group

results: those who thought they were pulling alone pulled stronger than those who thought they were pulling as part of a team
When will social loafing NOT occur? (6)
if 1 of the following is present:
- people believe their own performance can be identified
- the task is important
- people believe their efforts are necessary for the success of the group - missed this one
- the group will be punished for poor performance
- the group is small
- the group is cohesive
How do you reduce social loafing in academics? (3)
- limit the scope of the project
- keep the groups small
- use peer evaluation
Individual Evaluation Pathways (2)
Easy Task --> Social Facilitation --> Enhance

Hard Task --> Social Facilitation --> Impaired
Group Evaluation Pathways (2)
Easy Task --> Social Loafing --> Impaired

Hard Task --> Social Security --> Enhanced
the loosening of normal constraints on behaviour when people are in a group, leading to an increase in impulsive and deviant acts
What causes deindividuation? (4)
- arousal
- anonymity
- lack of individual responsibility
- lowered self-awareness (not focused on morals)
Examples of Deindividuation
- Internet Trolls
- Mob Mentality
- Collective Phenomena
Trick or Teat Experiment
- study of 1300 kids trick or treating
- 2x2 study
- alone vs in a group

- researcher left the kid(s) alone with a bowl of candy that said "take 1" after either identifying the kids or leaving them anonymous

results: alone and in a group, kids took more candy if they were anonymous
Costume Experiment
- female participants asked to put on a costume (either a nurse uniform or a robe that resembled the KKK)
- half were identified, half remained anonymous
- told they were to deliver shocks to a confederate (who was very obnoxious and annoying)

- KKK outfits = deliver stronger shocks (almost the same for identification levels)
- Nurse outfits = deliver weaker shocks (4x weaker if anonymous)

Why? Anonymous nurses were less self-aware and therefore were more conscientious to others
Process Loss
Any aspect of group interaction that inhibits good problem solving
Group Candidates Test
- groups given information packets on 2 candidates
- Group A = everyone has the same information packets with the 8 positives, and 4 negatives
- Group B = everyone has different information packets (4 negatives, 2/8 positives)

- 24% of Group B pick candidate 1

Why? groups tend to focus on the information they all share and ignore the unique information the individuals alone possess

- seek outside opinions
- create sub-groups - missed this one
- seek anonymous opinions from within the group
Risky Shift
alone, individuals will pick a risky option, but as a group will pick an even riskier option

ex. alone, a 50% success rate is enough to get the individual to participate in an activity. As a group, the success rate drops to 30%

- get your delivery truck to the destination the fastest
- get paid 60 cents - time
- fastest way is to use the 1-lane road
- eventually, opponents share the one-lane road

Variation: each opponent has a gate on the 1-lane road that they control - you lose significantly more $ in this variation

- it is nice
- it is not exploitable
- it is forgiving
- it is transparent
a form of communication between opposing sides in a conflict, in which offers and counter-offers are made and a solution occurs only when both parties agree
