“Although the scientific investigations of group

work are but a few years old, I don’t hesitate to

predict that group work – that is, the handling of

human beings not as isolated individuals, but in

the social setting of groups – will soon be one of

the most important theoretical and practical fields

… there is no hope for creating a better world

without a deeper scientific insight into the …

essentials of group life.”

Kurt Lewin (1943)



Overview

• What is a group?• Why groups are important• Nature and types of groups• What does it take to have a productive group?• Stages of group development • The field of group dynamics • Kurt Lewin• Summary questions



Can you Imagine your Life without

Belonging to Other People? • Membership in groups is inevitable and ubiquitous. • We are not able to survive without belonging to groups –

we are born into one, and interact in groups for most of our lives

• Our personal identity is derived from the way in which we are perceived and treated by other members of groups we belong to.

• Understanding group dynamics is essential to – Maintaining a viable family– Effective business and industries– Education– Long term maintenance of psychological health

• Knowledge of group dynamics can and will change your life



Group Dynamics

• Group dynamics is the scientific study of– The nature of groups– Behavior in groups– Group development– Interrelations between groups and individuals– Interrelations between groups and other

groups



A Group is a Number of Individuals who …

a. Join together to achieve a goalb. Are all affected by the same event – they are interdependent c. Interact with one anotherd. Perceive themselves as belonging to a groupe. Whose interactions are structured by a set of rules and

normsf. Influence each otherg. Are trying to satisfy some personal need through their joint

association

Which definition(s) do you agree with?



The Group Definition We are Going to Work with

• Two or more individuals

• In face-to-face interaction

• Each member is aware of – Positive interdependence as they strive to achieve

mutual goals– His/her membership in the group– The others who belong to the same group



Group Structure: Roles and Norms

• Roles– differentiate the responsibilities of group members

– Set of expectations defining the appropriate behavior of an occupant of a position toward other related positions

• Norms– integrate members’ efforts into a unified whole

– Common beliefs regarding group members’ appropriate behavior, attitudes and perceptions; (implicit and explicit) rules that regulate the behavior of group members



Roles and Status

• Role conflict, Milgram’s study of obedience (1974)• Status:

– Function of the degree to which an individual’s contribution is crucial

– How much power (control over outcomes) an individual has

– The extent to which the person embodies some idealized/admired characteristic.

– Status and power usually go hand in hand, but not always



Norms

• Group’s common beliefs about appropriate behavior, attitudes, perceptions; help maintain behavioral consistency, and predict other members’ behavior

• Not imposed, develop out of the interaction among members Social products

• Muzafer Sherif’s (1936) study• Newcomb’s (1943) study of group norms at

Bennington College



The Group Performance Curve



Pseudo group Members assigned to work together, but perception of competitive structure. Performance below individual level.

Traditional work group Members assigned to work together, but are held accountable individually perception of individual work structure. Members seek information from each other, but are not motivated to share information. Conscientious members feel exploited do less.

Effective group positive interdependence, clear operational goals, constructive conflict resolution, distributed leadership, individual accountability

High performance group: effective groups + high level of commitment members have for each other and for the success of the group



An Effective Group …

• Achieves its goal

• Maintains good working relationships among members

• Adapts to changing conditions in the world

How can we establish an effective group? What do we need to do?



If you Want an Effective Group

1. Establish clear, operational and relevant group goals that create positive interdependence and evoke a high level of commitment from every member

2. Establish effective two-way communication 3. Make sure that leadership and participation are

distributed among all group members.4. Make sure power is distributed among group

members corresponding to the needs of group members



5. Match method of decision making with the needs of the situation with the

1. Availability of time and resources

2. Size and seriousness of the decision

3. Amount of member commitment needed to implement the decision. Consensus rules!

6. Encourage structured controversies.

7. Ensure that members face their conflicts of interests, use integrative negotiations and mediation to resolve their conflicts.

Development of Groups over Time

• Recurring phase theories• Sequential stage theories

– Tuckman’s (1965) five stages (forming, storming, norming, performing, and adjourning), involving nondirective, passive leaders.

– What happens if the group leader intervenes to ensurethat the group functionsproductively?



Stages of Group Development

1. Defining and structuring procedures

2. Conforming to procedures and getting acquainted

3. Recognizing mutuality and building trust

4. Rebelling and differentiating

5. Committing to and taking ownership of the goals, procedures, and other members

6. Functioning maturely and productively

7. Terminating



Stages of Group Development



The Field of Group Dynamics

Relationship among theory, research, and practice



History of the Field of Group Dynamics

• Gained prominence in the early 1940s – goal: maintain a democratic form of government and solve current problems

• 2 interrelated movements in psychology– Scientific study of group dynamics– Application of group dynamics theory how to train leaders and group members

in the social skills necessary for democratic groups• Triplett (1898) -> social facilitation-impairment studies, social

interdependence, social loafing• 1920s-30s: are individuals or groups more productive? -> research on social

interdependence, conformity, group polarization, • Late 1930s and 40s -Lewin, Newcomb (1943), Whyte (1943); Lewin, Lippitt

and White (1939) study of the effect of leadership styles on group dynamics• Starting with the 1950s social psychology focused on the individual as the

unit of analysis (Festinger’s studies on social communication, social comparison, cognitive dissonance, Heider’s attribution theory (1958)

• 1980s and 1990s – resurgence of group dynamics (Deutsch, Johnson & Johnson, Tajfel, Moscovici)



Kurt Lewin (1890-1947)• "If you want truly to understand something, try to

change it" • "Nothing is as practical as a good theory." • A theorist and a doer• Main goal: construct an empirically based theory of human

behavior• Action research – social science theory should not just

advance knowledge, but also solve questions that have significant social value

• Field theory analysis – the "proposition that human behavior is the function of both the person and the environment: expressed in symbolic terms, B = f (P, E)."

• He pioneered the use of theory, using experimentation to test hypothesis – manipulating complex variables in natural settings.

• He and his associates developed a wide variety of theories and research programs that defined the field of group dynamics



Summary

• Why study group dynamics? • What is a group? • Why are roles and norms essential for groups?• What characteristics distinguish effective groups from

traditional groups? • What stages do groups go through? • What is the relationship among research, theory and practice? • "If you want truly to understand something, try to change it“ –
