groups 1: intragroup processes Flashcards
(49 cards)
what is a group?
two + individuals who define themselves as members of a group
what are the different scales and kinds of groups?
intimacy group: friends and family
task group: goal
social category: demographic
loose association: common place in time
what motivates people to join groups?
the need to belong
we have an intrinsic motivation to affiliate with others and be socially accepted
what are the characteristics of an intimacy group
high: interaction importance common goals common outcomes similarity entitativity (perception of group as single entity)
low permeability
long duration
small size

how did children define groups
children were asked to point to different types of pictures that would categorise groups along different dimensions
key distinct features included:
sharing, loyalty and liking for intimacy groups
helping and interdependence for task groups
familiarity, similarity, shared preference, common knowledge for social category
no continuance and low permeability for loose associations
how does task type affect group potential
additive tasks like pulling a rope - sum of member’s indiviudal perfromance
disjunctive like decison making best member’s individual performance
conjunctive like moutntain climbing - weakest memver’s indivudal performance
what is group cohesion
the force that binds members to the group and induces them to stay with the group
what is task cohesion
the shared commitment to the groups task
what is interpersonal cohesion
the attraction to the group
what is group potential
the peformance that would occur if the members of a group work independently of each other, not as a group - a benchmark to evaluate actual group performance
what is social facilitation
an improvement in the performance of well-learned, easy tasks and a worsening of performance of poorly learned, difficult tasks due to the presence of members of the same species
can be facilitative or inhibitory
e.g cyclists faster in presence of others
how did Enigman et al. test whether social facilitation was species specific
Engaged chimpanzees and children in a task where they could retrieve food items from apparatus
Varied whether the individual was working on the task with another individual present, observing or competing.
Results
For chimps the act of being observed did not make a big difference and the competitive context made a strong difference
For children the pattern was different, the presence of another individual was enough to increase performance.
Authors argue that this may point to an evolutionary shift with additional sensitivity to being watched, ties into reputation and what others think of you.
BUT: this is comparing adult chimpanzees to preschool children
how did Sniezek & Henry (1989) investigate collective intelligence
putting individuals in a group made responses 23% more accurate when
MBA students were asked to rate the likelihood of dying form each of a list of potential causes
group discussion facilitates the process of arriving at the correct answer
BUT is this task specific
what is Zajonc’s drive theory of social faciliation
presence of others –> arousal –> increase in performaing dominant responses –> if correct, social faciliation, if incorrect social inhibition
what is group think?
a syndrome of poor group decision making where members of a cohesive ingroup strive for unanimity at the expense of a realistic appraisal of alternative courses of action
agree to conform despite disagreement
what are the antecedents of group think
high cohesiveness
homogeneous members, isolation, directeive leadership, unsystematic procedures,
stressful situations
what are the symptoms of group think
overestimation of the group
close-mindedness
increased pressure towards uniformity
defective decision making
illusions of invulnerability: excpessive optimism, encouraging extreme risks
collective rationalisation: discount warnrings, do not reconsider bad assumption, no motivation to adapt course of action
belief in inherent morality: believe in the rightness of their cause so ignore ethical consequences of their deicsions
stereotyped views of outgroups: negative views of enemy make effective responses to conflict seem unnecessary - inoculation effect
direct pressure on dissenteres: members are under pressure not to express arguments against any of the groups view
self censorship: doubts and deviations from the perceived group consensus are not expressed
illusins of unanimity: the majority of view and judements are assumed to be unanamous
self appointed mindguards: members protect the group and leader form infroamtion that is problematic or contradictory to the group cohesiveness, view and decisions
what are the consequences of group think
incomplete consideration of alternatives
incomplete considertaon of objectiv es
littel to no risk determination of the preferred decisioin
no reevaluaiotn of laready rejected ideas
bias in infomratoin percpetion
rediced probaility of success
what motivaitonal gains are there from being in a group
social competition: members want to outperform each other during group tasks where the indivudal contributions are identifiable
social compensation: motivation gain in groups if stronger group members increase their effort to compensate for weaker member’s suboptimal performance
kohler effect: weaker group members work harder to avoid responsibility of poor performance
what motivational losses are there from being in a group
social loafing: group members reduce their effort because indivudal contributiosn are not identifiable
what did Latante et al., 1979 find about social loafing
Measured individual contribution of clapping in a group context
Recorded sound pressure produced by individual members
Plotted against group size
as size of group increases, the contributions of individual members decreases
BUT efficiency motive, fear of evaluatoin, or imitaiotn
