Social influences on behavior
Human behavior is influenced powerful by the social environment in which it occurs.
We behave as we do not just because of who we are, but also because of the social situations in which we find ourselves.
Social pressure: the entire set of psychological forces that are exerted on us by others whether real or imagined.
We are most strongly influenced by those people who are physically or psychologically closed to us.
Social pressure arises from the ways we interpret and respond emotionally to the social situations around us.
It promotes our social acceptability and helps create order and predictability in social interactions.
Facilitating and interfering effects of an audience
Social facilitation: the enhancing effect of an audience on task performance.
Social interference: a decline in performance when observers are present.
Facilitation of ‘easy’ tasks, interference with ‘hard’ ones
The presence of others facilitates performance of dominant actions and interferes with performance of nondominant actions.
Dominant actions: actions that are so simple, speciestypical, or well learned that they can be produced automatically, with little consciously thought
Nondominant actins: actions that require considerable conscious thought or attention
The presence of an audience increases a person’s level of drive or arousal.
The arousal increases the person’s effort, which facilitates dominant tasks where the amount of effort determines the degree of success.
The arousal interferes with controlled, calm, conscious thought and attention and thereby worsens performance of nondominant actions.

The primary cause of social interference is evaluation anxiety.
Social interference increases when the observer are high in status or expertise and are present explicitly to evaluate. It also increases when subjects are made to feel unconfident and more anxious about their ability.
It decreases when subjects feel confident about their ability.
Choking under pressure: the working-memory explanation
‘Choking’ is especially likely to occur with tasks that make strong demands on working memory.
The worry takes space out of the memory span.
Choking on academic tests
Distracting and disturbing thoughts flood their minds and interfere with performance on tests.
With sufficient pressure, choking can even occur in students who normally do not suffer from tests anxiety. It occurs specifically with tests items that make the highest demands on working memory.
Stereotype threat as a special cause of choking
Stereotype threat: threat that test-takers experience when they
