What traumatic event does Zitkala-Sa describe at the school?

The forcible cutting of her long hair

Why was the cutting of her hair so humiliating to Zitkala-Sa?

Among her people, shingled hair was worn by cowards and mourners

How is a group defined?

As an organised system of two or more interacting and interdependent individuals who have common motives, role relationships and norms that regulate behaviour.

How does a group differ from a crowd?

A group has structure, interdependence and a sense of belongingness, whereas a crowd is a chance collection of people without structure or interdependence.

What is groupthink and how can it be prevented?

It is a tendency of cohesive groups to make uncritical decisions for the sake of unanimity; it can be countered by encouraging critical thinking, alternatives and outside opinions.

Distinguish primary and secondary groups.

Primary groups (family, caste) are pre-existing, face-to-face and emotionally close; secondary groups (a political party) are joined by choice and more impersonal.

What did Tajfel's minimal group paradigm show?

That even when groups are formed on a flimsy, meaningless basis, members still favour their own ingroup over the outgroup.

Differentiate social facilitation and social loafing.

Social facilitation is improved performance in the presence of others when individually evaluated; social loafing is reduced individual effort in pooled collective tasks.

What is group polarisation and why does it occur?

It is the strengthening of a group's initial view after discussion, due to hearing new supporting arguments, a bandwagon effect and identification with the ingroup.

This chapter examines what groups are and how they influence individual behaviour. A group is an organised system of two or more interacting and interdependent individuals who share common motives, role relationships and norms that regulate behaviour. Groups differ from crowds, audiences, mobs and teams. People join groups for security, status, self-esteem, satisfaction of psychological and social needs, goal achievement and access to knowledge and information. Group formation is facilitated by proximity, similarity and common motives and goals. Tuckman described five developmental stages: forming, storming, norming, performing and adjourning. Group structure has four elements: roles, norms, status and cohesiveness. Excessive cohesiveness can produce groupthink, where the desire for unanimity overrides realistic appraisal and leads to poor decisions. Groups are of several types: primary and secondary, formal and informal, and ingroup and outgroup, with the ingroup viewed favourably and the outgroup negatively, as shown by Tajfel's minimal group paradigm. Group influence on individual behaviour includes social facilitation (improved performance in the presence of others when individually evaluated) and social loafing (reduced individual effort in collective tasks). Social loafing can be reduced by making contributions identifiable and increasing task importance and group cohesiveness. Group polarisation is the strengthening of a group's initial position after discussion, sometimes leading to extreme decisions.
