Group: A set of individuals who have at least one of the following characteristics: Direct interactions, joint membership in a social category, or a shared, common fate, identity, or set of goals.

Collective: An assembly of people engaging in a common activity but having little direct interaction with each other.

Stages of Group Development: 1) Forming: Members orient themselves and often act in polite exploratory ways. 2) Storming: Members try to influence group to best fit their own needs. Can lead to conflict/hostility and excitement about what can be achieved. 3) Norming: Members reconcile conflicts and develop a common sense of purpose and perspective. Establish norms and roles and feel more commitment. 4) Performing: Members perform tasks and maximize group performance. 5) Members disengage from the group.

Group Roles: Instrumental roles – help the group achieve its tasks. Expressive roles – provide emotional support and maintain morale. Homogenous group = everyone with same skills. Congruent group = people with necessary skills assigned to proper tasks. Incongruent group = people with necessary skills assigned to improper tasks.

Norm: Rule of conduct for members of a group.

Group cohesiveness: the extent to which forces push group members closer together, such as through feelings of intimacy, unity, and commitment to group goals.

The Zajonc Solution: Resolves contradiction from Triplett fishing rod research. Presence to performance requires 3 steps: 1) Presence of others generates arousal, which energizes behavior. 2) Increased arousal enhances tendency to perform the dominant response. 3) The quality of performance varies according to the type of task (easy/hard).

Social Facilitation: A process whereby the presence of others enhances performance on easy tasks but impairs performance on difficult tasks.

Zajonc's Mere Presence Theory: The proposition that the mere presence of others is sufficient to produce social facilitation effects

Evaluation apprehension: A theory that the presence of others will produce social facilitation effects only when those others are seen as potential evaluators.

Distraction – conflict theory: A theory that presence of others will produce social facilitation effects only when those others distract from the task and create attentional conflict.

Social Loafing: A group-produced reduction in individual output on tasks where contributions are pooled.

Collective Loafing Model: The theory that individuals will exert effort on a collective task to the degree that they think their individual efforts will be important, relevant, and meaningful for achieving outcomes that they value.

Deindividuation: the loss of a person's sense of individuality and the reduction of normal constraints against deviant behavior. Arousal + Anonymity + Reduced individual responsibility = deindividuation.

Social Identity Model of Deindividuation Effects (SIDE): A model of group behavior that explains Deindividuation effects as the result of a shift from personal identity to social identity.

Process Loss: The reduction in group performance due to obstacles created by group processes, such as problems of coordination and motivation. Additive task = product is sum of all group contributions. Is particularly vulnerable to social loafing. Conjunctive task: group product is determined by the individual with the poorest performance: IE mountain climbing. Disjunctive task: group product is determined by the individual with the highest performance.

People brainstorming as a group come up with a greater number of better ideas than the same number of people working individually. FALSE

Brainstorming: A technique that attempts to increase the production of creative ideas by encouraging group members to speak freely without criticizing their own or others' contributions.

Factors that reduce effectiveness of group brainstorming:

Production blocking: People forget ideas while they are waiting their turn to speak.

Free riding: Others get less motivated to talk when they hear others contribute ideas. Think their contributions are less necessary.

Evaluation apprehension: Are reluctant to suggest crazy ideas for fear of looking foolish. Even if idea is shared, they might spend too much time thinking of reasons to justify it.

Performance matching: Members only work as hard as they see others work.

Effectiveness of electronic brainstorming:

Less production blocking – can type ideas whenever

Less freeriding – computer can keep track of member input

Less Evaluation Apprehension – anonymous comments can be made.

Less Performance matching – group members spend less time focusing on others when they type themselves.

Group members can benefit by seeing the ideas of others, which can inspire new ideas.

Group members' attitudes about a course of action usually become more moderate after group discussion. FALSE

Group Polarization: The exaggeration through group discussion of initial tendencies in the thinking of group members. Can be created by 1) Persuasive arguments theory 2) Social comparison 3) Social categorization

1) Persuasive arguments theory: the greater number and persuasiveness of arguments to which members are exposed, the more extreme their attitudes become.

2) Social comparison: If most group members lean in one direction, individuals may adopt a more extreme attitude in the same direction.

3) Social categorization

Groupthink: A group decision making style characterized by excessive tendency to seek concurrence among group members. 3 things contribute: 1) Highly cohesive groups are more likely to reject members with deviant objections 2) Groups made of people from similar backgrounds, isolated from other people, directed by a strong leader, or lacking systematic procedures for reviewing decisions 3) stressful situations.

Prevent groupthink by 1) Avoiding isolation and 2) reduce group pressures to conform by explicitly encouraging criticism and not taking a strong stand early in the group discussion.

Escalation Effect: The condition in which commitment to a failing course of action is increased to justify previous investments.

Biased Sampling: The tendency for groups to spend more time discussing shared information (information already known by all members) than unshared information (information only known by one or a few members.)

Transactive memory: A shared system for remembering information that enables multiple people to remember information together more efficiently than they could alone.

Group Support Systems: Specialized interactive computer programs that are used to guide group meetings, collaborative work, and decision-making processes.

Social Dilemma: Situations in which a self-interested choice by everyone creates the worst outcome for everyone. IE Prisoner experiment.

Prisoner's dilemma: A type of dilemma in which one party must make either cooperative or competitive moves in relation to another party. The Dilemma is typically designed so that the competitive move appears to be in one's self interest, but if both sides make this move, they both suffer more than they had both cooperated.

Resource Dilemma: Social dilemmas involving how two or more people will share a limited resource. 1) Commons dilemma ("take-some dilemma"): People take as much as they want from a limited, nonrenewable resource = nothing left for anyone 2) Public goods dilemma: all individuals have to contribute resources to a common pool. IE libraries, parks, blood supply.

Large groups are more likely than small groups to exploit a scarce resource that the members collectively depend on. TRUE

Social Value Orientation: 1) prosocial cooperative orientation – seek to maximize joint gains 2) individualist orientation – maximize own gain 3) competitive orientation – maximize own gain relative to that of others.

Graduated and Reciprocated Initiatives in Tension-Reduction (GRIT): A strategy for unilateral, persistent efforts to establish trust and cooperation between opposing parties.

Integrative agreement: a negotiated resolution where all parties obtain outcomes that are superior to a 50-50 split.
