Social Thinking
Social Psychology*scientific study of how we think about,
influence, and relate to one another*how individuals affect each other
Social Context*the real, imagined, or symbolic presence of
other people; the activities and interactions that take place among people; the settings in which behavior occurs; and the expectations and social norms governing behavior in a given setting.
Social ThinkingAttribution Theory
*tendency to give a causal explanation for someone’s behavior, often by crediting either the situation or the person’s disposition
Social Thinking*Fundamental Attribution Error
*tendency for observers, when analyzing another’s behavior, to underestimate the impact of the underestimate the impact of the situationsituation and to overestimate the impact of overestimate the impact of personal dispositionpersonal disposition
*dual tendency to overemphasize personal traits while minimizing situational inferences.
***Always try to find a situational explanation for strange or bizarre behavior of others before “blaming” them with dispositional explanations.
et.al. Did the person brake suddenly in front of you because he is a jerk, or because a dog ran out in front of his car?
Social Thinking*Attitude
*belief and feeling that predisposes one to respond in a particular way to objects, people and events
**OUTSIDE INFLUENCES ON WHAT WE SAY AND DO ARE MINIMAL (2002, with most Americans supporting preemptive war in Iraq, most Democrats publicly supported the idea while having private reservations)
** THE ATTITUDE IS SPECIFICALLY RELEVANT TO THE BEHAVIOR (proclaim love while yelling at mate, cherish honesty while cheating on test)
**WE ARE KEENLY AWARE OF OUR ATTITUDES (we mindlessly follow habit or others’ expectations while our attitudes lie dormant)
Social ThinkingOur behavior is affected by our inner attitudes
as well as by external social influences
Internalattitudes
Externalinfluences
Behavior
Social ThinkingFoot-in-the-Door Phenomenon
*tendency for people who have first agreed to a small request to comply later with a larger request
*Social Roles*set of expectations about a social position*defines how those in the position ought to behave*when you adopt a new role (college student, marry, new
job), you strive to follow the social prescriptions. May feel phony at first while you “act” the role.
No one “teaches” you your role.
*Social Roles: involves a person’s knowledge about the sequence of events and actions that are expected of a particular social role.
*Cognitive Dissonance*When we voluntarily undergo
unpleasant experiences.*voluntarily produce discomfort with
ideas that clash with their attitudes and values
*et. al. Republican speaker in a Democratic auditorium
*Cognitive Dissonance Theory*people are motivated to avoid uncomfortable state of
dissonance*must change either one’s behavior or one’s cognitions*et.al. when we become aware that our attitudes and our
actions clash, we can reduce the resulting dissonance by changing our attitudes
Generally speaking, when people’s cognitions and actions are in conflict (a
state of dissonance) they often reduce the conflict by
changing their thinking to fit their behavior.
Social InfluenceConformity
*adapting one’s behavior or thinking/opinions to coincide with a group standard
*used to avoid rejection
Conformity increases whenConformity increases when:
*one is made to feel incompetent or insecure
*the group is unanimous
*one admires the group’s status and attractiveness
*one has made no prior commitment to any response
*others in the group observe one’s behavior
*one’s culture strongly encourages respect for social standards

Conformity – Solomon Asch (1950s)Group norm behaviorClassic experiment

ComplianceConforming to requested behavior
