A theoretical framework (chpt.3) Flashcards
Framework
five elements
- group members
- group tasks
- group interaction
- group output
- group context
Top down effects
occur when characteristics at the group level influence group member behavior, thoughts, and feelings
Bottom up effects
occur when characteristics at the individual level determine at the group level
Potential performance
Potential Performance= f (group member resources,task demands) potential performance (what a group could potentially achieve given group member resources and task demands and actual performance what the group actually does achieve.
Steiner’s classification of group tasks
Divisible tasks can be divided into subtasks whereas this is not possible for unitary tasks lifting a piano is a unitary task there are no subtasks he distinguished between optimizing and maximizing tasks
4 task types
- additive
- disjunctive
- conjunctive
- discretionary
Steiner’s Typology of tasks Additive Task
Potential performance of the group is given by the sum or average of individuals inputs ex. filling envelopes, pulling a rope, brainstorming, making judgements and estimates
Steiner’s Typology of tasks Disjunctive Task
Potential performance of the group is given by performance of the worst member ex. decision making, problem solving
Steiner’s Typology of tasks Conjunctive Task
Potential performance of the group is given by performance of the worst member ex. mountain climbing, assembly line
Steiner’s Typology of tasks Compensatory Task
Potential performance is given by any combination of individual performances up to the discretion of the group ex. making music, designing a car
Group Process
determine how individual inputs of group members are combined to lead to a group output
Action Performance
is a function of potential performance and group processes.
Actual performance= potential performance - process loss
Motivation loss
occurs when members are not optimally motivated
Coordination loss
occurs when group members do not combine their potential contributions in an optimal way
A two way classification of outcomes level of analysis
Performance
Individual- Individual level performance amount of influence, personal production, speed of performance
Group- Group level performance, quality of decision, correctness of solution, group productivity, time required
A two way classification of outcomes level of analysis
Affective
Individual- Individual level affective responses satisfaction, respect and a status, mood, and motivation
Group- Group level affective responses, group cohesion, group affective tone
A two way classification of outcomes level of analysis
Learning
Individual-Individual learning, task proficiency, Interpersonal skills, knowledge
Group-Group learning transactive memory
Structure
Groups have stable patterns of relationships among members
- norms
- roles
- hierarchies
- social networks
- communication networks
Norms
groups are based on coordinated actions
- reciprocity give and take
- equity you get as much as you put in
- equality
Descriptive norms
Shared expectations that define what most people do, or do not do, in a particular situation.
Defines what is “normally” done.
Violating such norms are considered “unusual.”
Prescriptive Norms
Shared expectations that define what people should, or should not, do in a particular situation.
Violating such norms is considered “bad.”
“Injunctive norms”
Sherif’s study
Autokinetic effect in a dark room we focus on lit objects research on dot of light “How far did the dot move?”
Formation of group norms: Participants in a dark room were asked to judge how far a dot of light moved.
Autokinetic effect (ambiguous stimulus)
Phase 1: Made judgments alone.
Phase 2: Made judgments in groups.
Internalizing the group norm:
Phase 3: Participants made judgments alone again continued to follow the group norm (even without social pressure to do so).
Preservation of group norms:
In another study, confederates (the experimenter’s secret helper) deliberately made extreme judgments, which influenced the group to establish its norm closer to that extreme judgment groups continued to follow that norm for a while even when the confederate was replaced by another participant.
Asch’s Conformity Studies
Participants followed the incorrect majority 37% of the time.
Fifty percent conformed for at least half of the times in response to the incorrect majority.
On the other hand, 25% of the participants never conformed.
When alone again (in privacy), the participants who had conformed changed their answers.
Sherif vs. Asch Studies
Sherif: Task involved making uncertain, subjective judgment; participants turned to each other for guidance.
Informational Influence.
Private conformity (true acceptance).
Change is maintained whether or not the group is present.
Asch: Task had clear, objective answer.
Normative Influence.
Public conformity (superficial change).
Change occurs only when the group is present.
Minority Influence
“Minority” (i.e., part of the group that is smaller in numbers)
The minority need to dissent consistently to bring about change in the group
Indirect Influence
Changing thoughts on issues related to the main issue, rather than on the main issue itself.
Example: if the main issue of discussion was raising tuition, then changing thoughts on the issue of raising other fees
Nemeth’s Theory
Majority influence
Triggers stress
Narrows attention and cognitive efforts to the majority’s arguments
Convergent thinking (one-sided thinking)
Minority influence
Triggers careful reconsideration of the issue (open mind)
Divergent thinking (considers multiple viewpoints) more careful consideration of the issue; more creativity
