Chapter Three: Group Development
Task and Social Dimensions: All decision-making groups have both task and social dimensions.
 How group members are treated and the quality of their relationships within the group can markedly affect task accomplishment.
 Neither the task nor the social dimension can be ignored for decision making to be successful
 Cohesiveness enhances group productivity unless overemphasized
.
Task dimension is the work performed by the group and its impact on the group
Social dimension is the relationships that form between members in the group and their impact on the group as a whole.
Outputs are results of the group's interactions
Productivity is the result of the efficient and effective accomplishment of a group task
Cohesiveness is the degree to which members feel a part of the group, wish to stay in the group, and are committed to each other and to the group's work.
The main strategies for instilling cohesiveness in groups are:
1. Encourage compatible membership
2. Develop shared goals
3. Accomplish tasks
4. Develop a positive history of cooperation
5. Promote acceptance of group members

This is a sarcastic look at why we form groups. Unfortunately, this is the way many people think about teamwork.

Forming: Why do we Join Groups?
The reasons individuals join groups have noticeable effects on productivity and cohesiveness of those groups
Interpersonal Attraction--We seem to be attracted to others when we perceive them to be similar to us in personality, attitudes and beliefs, ethnic origin, sexual orientation, and economic status. Physical attractiveness is also a source of attraction
Attraction to Group Activities
 Attraction to Group Goals
 Establishment of Meaning and Identity
 Fulfillment of Unrelated Needs
Storming: Tension in Groups
 Finding the level of tension that solidifies the group and effectively managing group tension are important factors in successful group development
Primary Tension--tension when a group first congregates
 Joking, laughing, chatting, superficial conversation helps break primary tension
Second Tension-the stress and strain that occurs within the group later
 Tension can be a positive force: It can energize the group, challenge members to think creatively, bring the group together.
 The challenge is to manage secondary tension within tolerable limits.
 If the groups is not able to accomplish tasks and maintain a satisfying social climate then there is excess tension.
 A competent communicator will handle secondary tension by:
 Keeping a civil tongue
 Tolerating, even encouraging, disagreement and deviance
 Being an active listener
Norming: Regulating the Group
 Types of Norms
 Explicit--norms stated directly
 Implicit-observed rules
 Purpose and Development of Norms: The main purpose is to achieve group goals
 Conforming to Norms
 Conditions for Conformity to Norms
The stronger the cohesiveness in the group, the greater is the conformity to group norms
Conformity is greater when individuals expect to be group members for a long time
Conformity is greater when individuals perceive that they have a somewhat lower status in the group than other members or are not accepted by the group
 Nonconformity

Closer Look: Hazing Rituals
 Groups harshly initiate their newcomers because the harder it tis to get into a group the greater will be the loyalty and commitment to the group once membership has been attained
 A harsh initiation provides the group with valuable information about the newcomers
 A harsh initiation discourages newcomers who have a weak commitment to the group or have a halfhearted desire to join the group
 A harsh initiation may convince newcomers how dependent they are on long time members
Performing: Group Output
Individual Versus Group Performance: A key to successful group performance is putting together a team composed of members who do not share ignorance, but instead pool non overlapping areas of knowledge
 The average group member pursued their topic for 58 seconds at a time before diverting to an irrelevant topic.
 Groups can remember more accurately than individuals.
 Groups outperform individuals when both the group and any individual compared are without expertise on the task.
 Groups usually outperform an individual when both the group and the individual have expertise and the task is an especially complicated and complex one.
 Expert groups outperform their best member 97% of the time,
 Individuals outperform groups when groups establish noms of mediocrity.
 Individuals outperform groups when groups become too large.
Social loafing -the tendency of individual group members to reduce their work effort as groups increase in size
 Risk Taking and Polarization
Risky shift phenomenon- groups make more risky decisions than individuals.however research has found that groups sometimes have a conservative shift so it is better to say that groups polarize.
Group polarization is the group tendency to make a decision after discussion, that is more extreme, either riskier or more cautions, than the initial preferences of group members
Kolb's Learning Cycle
Different learning styles cause individuals to work differently in groups
Concrete experience learning style
Doers, experiences
 Learn from events they observe or activities they participate in.
 Concerned with unique, particular experiences rather than theories and generalizations.
 Likely to help the group do than to help the group synthesize information
|
Abstract Conceptualization Learning Style
Thinkers, synthesizer
 Process information by reading and solitary study.
 comfortable working alone, can perceive broad patterns, readily understand theoretical material, and can pull together information form a variety of sources.
 Logical and emphasize thinking as opposed to feeling.
 They like to pull group research together.
|
Reflective Observation Learning Style
Thinkers
 Prefer to gain perspective by standing back, gaining perspective and distance, and thinking about it reflectively.
 They mull information in their minds, talk to others about it.
 They learn particularly well by writing about the experience.
 More likely to help the group think than to help the group do
|
Active Experimentation Learning style
Doer
 Individuals learn by trying out difference things until they find ways that work.
 They do rather than observe.
 Effective in a crisis because they can think and problem solve on their feet.

Newcomers and Group Development
Nature of Group
?If you were leader of a team, what would you do to help newcomers become part of the group?
Several Characteristics of a group directly affect the acceptance of a newcomer
(Moreland and Levine 1987)
 The level of group development affects the acceptance of newcomers
The older the group the harder it is for a newcomer to become part of the system
 The level of group performance affects the acceptance of the newcomer into the group
If a group is working poorly they are more likely t accept newcomers than if they are functioning well
 The degree of turnover in a group affect acceptance of newcomers.
Groups accustomed to frequent entry and exit of members will accept newcomers more readily
Newcomer Strategies to Improve Acceptance into the Group
 Conduct a thorough reconnaissance: assess the group you may be joining
 Play the role of a newcomer
 Seek advice from longtimers
 Avoid disagreements with old-timers
 Talk less than old-times do as a sign of respect
 Seek patrons within the group: Find a mentor
 Collaborate with other newcomers
Focus on Gender/Culture: Gender/Ethnicity and Group Development
In mixed sex groups, men are normatively assumed to be the task experts whereas women are assumed to be the relationship experts.
This norm emphasizes a lower status role for women (keeping the peace) and a higher status role for males (decisions making)
The 20 Percent Rule
Researchers have observed that discrimination against minorities (and presumably women) drops substantially when no less than 20 percent and no fewer than two members are from a minority
