Q

Social brain hypothesis

A

humans are drawn to groups for survival and reproduction, and this is why we join groups. Large brains among primates reflect this tendency, the larger the primate’s brain, the more it’s drawn to form groups.

Q

Key features of a group

A

(1) roles – individuals expected behaviors, in the forms of instrumental roles, which help the group achieve its taste, and expressive roles, which provide emotional support and maintain morale. (2) Norms – rules of conduct, can be formal or informal, and pressure is exerted on members that deviate from the norm. (3) Cohesiveness – closeness, the forces exerted on a group push its members closer together, casually related with group performance, can be affected in different ways as a function of cultural differences.

Q

Roach study

A

placed a flashlight in a simple maze and wanted to see how fast these roaches could complete the maze, first testing the roach by itself, then testing it with an audience of other roaches. Then redid this in a complex maze. Findings: the presence of other people (or roaches in this case) make you experience arousal causing a dominant response (social facilitation).

Q

Why does the presence of others cause arousal?

A

the presence of others makes us more alert, also because we are concerned about being judged, and because people are distracting. Divided attention (attentional conflict) produces arousal.

Q

Social loafing

A

The tendency for an individual to perform worse on a simple task or better on a complex/important task when individual performance isn’t evaluated. The presence of other people doesn’t make you aroused causing relaxation, which affects performance in the following ways: performance declines on an easy/unimportant task, and performance improves on hard/important tasks. People “loaf” (put in less work) less when… (1) individually evaluated/rewarded, (2) the task is important or meaningful, (3) the individual’s effort is necessary for success, (4) group expects to be punished for poor performance, (5) smaller groups, (6) group is cohesive. Opposite of social facilitation.

Q

Common goods dilemma

A

“tragedy of the commons,” use of the common resource is below the carrying capacity of the land. All users benefit if one or more users increase the use of the commons beyond the carrying capacity, the commons become degraded. The cost of the degradation is incurred by all users, unless environmental costs are account for and addressed in land use practices , eventually, the land will be unable to support the activity.
