1. Welcome to the study of groups and
their dynamics. This course has one
purpose: To describe and explain all things
related to people and their groups.
But, before we start our analysis, we have to
ask ourselves one question: Why? Why
study groups?
2. But Why Study
Groups?
Because groups hold the
secret to the Universe
Understanding groups
facilitates:
Understanding people
Understanding the
social world
Applications to
practical problems
Understanding
yourself
*The interpersonal universe, at any rate.
3. But Why Study
Groups?
Because groups hold the
secret to the Universe
Understanding groups
facilitates:
Understanding people
Understanding the
social world
Applications to
practical problems
Understanding
yourself
We see people
as individuals,
with private
selves; not units
in a system; but
they are
enmeshed in
groups
Each person you encounter is in dozens of groups, but we* see them as isolated individuals
4. What Groups Do . . .
They invent nearly
everything…
Thomas Edison’s team
Eli Whitney
The Wright Brothers
Zworykin (TV, turned
down by Westinghouse,
hired by RCA)
The Lunar Modules
The personal computer
(PARC ). . .
Applications
5. Marco Polo (actually, the
Polos)
Christopher Columbus
Lewis and Clark’s “Corps
of Discovery”
Shakelton’s “Endurance”
Hillary and Tenzing
Norgay’s climb of Everest
NASA missions….
Discover nearly
everything.
6. What Groups Do . . .
They make nearly
everything
Assembly lines
Production
teams
Building crews
Construction
teams
Service teams
7. What Groups Do . . .
They do much of the
world’s work
Work crews
Surgical teams
Custodial staff
Office staff
Military and police
squads
Flight crews
Team at Johns Hopkins
with Dr. Alfred Blalock,
Dr. Helen Taussig, and
Vivien Thomas
8. What Groups Do
But they also create
its beauty…
Bands and orchestras
Dance troupes
Artist circles and
communities
Writers clubs
Improvs
Cast and crew of a play or
performance
Flash crowds…
9. What Groups Do . . .
They make all the
decisions
business decisions:
executive boards, executive
teams
guilt and innocence: juries
wealth management:
investment groups
military decisions:
command groups
moral and ethical decisions:
courts, IRBs
(well, most of them, anyway)
10. What Groups Do . . .
They discover everything...
The invent everything...
They make everything...
They do the work....
They make the good...
They make the decisions...
They are where leadership
happens
Is it lonely at the top?
President John F. Kennedy with Advisors
Or do even extremely powerful leaders work
through and with groups?
12. Why Study Groups? For personal reasons
Chapter 1
Understanding groups
facilitates:
Understanding
people
Understanding the
social world
Applications to
practical problems
Understanding
yourself
12
Are other people the same
in every group they are in?
Are YOU the same person
in every group you are in?
13. However,
groups,
although
essential to
human
existence, are
not all good…
The Value of Groups
Groups also Cause Many of
the Problems in the world
Gangs
Criminal societies
Mobs
Riots
Rebels
Intergroup conflict
Alternative
religious/social groups

Each person who belongs
to a group defines, in part,
the nature of the group.
Who is in
the group?
How does
each person
fit in?
19. Size
Groups range in size from
2 (dyads) to the very large
(crowds and collectives)
The number of possible
relations in a group
increases as groups
increase in size.

between task
interaction and
relationship
interaction.

23. Goals
Chapter 1
Group Dynamics 7e
Groups seek a
variety of goals
McGrath Goal Model:
Generating
Choosing
Negotiating
Executing
23
24. Origins
Chapter 1
Group Dynamics 7e
Planned groups
(concocted and
founded) are
deliberately formed,
but emergent groups
(circumstantial and
self-organizing)
come into existence
over time (Arrow,
McGrath, & Berdahl,
2000).
24
25. Unity
Group cohesion, or cohesiveness, is the unity of a
group.
25
Origin
•From the
Latin
“haesus,”
meaning to
“cling to”
(e.g.,
adhesive,
inherit)
Definition
• The
solidarity,
unity,
integrity of
a group
Sources
• A group’s
cohesiveness
derives on a
number of
sources, such
as attraction,
commitment
to a task, and
so on.
26. Entitativity
Chapter 1
Group Dynamics 7e
Some groups “look like” groups, seem to be
entities (common fate, similarity,
proximity, and so on)
26

30. Chapter 3
Inclusion and Identity
Just as researchers in the natural
sciences use exacting procedures to
study aspects of the physical
environment, so do group researchers
use scientific methods to further their
understanding of groups. They
measure as precisely as possible group
processes, develop theories that
provide coherent explanations for the
group phenomenon they study, and
collect evidence to test the adequacy of
their predictions and assumptions.
What assumptions do researchers
make when studying groups?
What are the 3 critical requirements
of a scientific study of groups?
How do researchers measure group
processes?
What are the characteristics of and
differences between case,
experimental, and correlational
studies of group processes?
What theoretical perspectives guide
researchers’ studies of groups?

Chapter 3
Inclusion and Identity
Do humans, by nature, seek
solitude or inclusion in
groups?
When do people embrace
collectivism by putting the
group’s needs before their
own?
What processes transform an
individual’s sense of self into a
collective, social identity?

Inclusion and
Identity
The ancient taoist taijitu
symbolizes the synthesis of
the individual and the
collective.

33. Isolation to
Inclusion
Need to
Belong
All human beings, “have a pervasive drive to form and
maintain at least a minimum quantity of lasting,
positive, and impactful interpersonal relationships.”
Roy Baumeister & Mark Leary (1995, p. 497).
34. Isolation can be rejuvenating,
but:
• Isolated individuals (e.g., stranded
explorers) report negative effects
• Solitary confinement recognized as
a severe punishment
• People seek membership in a
variety of groups
• People build their “social capital”
by creating online and face-to-face
relationships

Psychological
intimacy
(emotional
loneliness)
Integrated involvement (social loneliness)
Different groups reduce different
types of loneliness
Adapted from Shaver and Buhrmester, 1983
39. Inclusion and
exclusion
Ostracism: Excluding
one or more individuals
from a group by reducing
or eliminating contact
with the person, usually
by ignoring, shunning, or
explicitly banishing them.
Researchers have studied reactions
to ostracism in various ways,
including
• The “life alone” paradigm
• The ball-toss paradigm (and
cyberball)
• The exclusion paradigm
41. Fight vs Flight Tend and Befriend
Withdrawal and freezing
Aggressive, combative
orientation
Attention to social cues
Increased motivation
Prosocial orientation
Reactions to Exclusion
Extreme Reactions to
Exclusion:
Attacks by the excluded on group members—
school shootings
42. Inclusion and Survival
• The evolution of
gregariousness (the “herd
instinct”)
• Leary’s sociometer theory
• Neurological reactions to
exclusion
Is the “need to belong” a FUNDAMENTAL need?
1. Operates in a wide variety of circumstances (does not
require special, unusual conditions)
2. Linked to emotional processes (concern, worry, etc., until
met)
3. Linked to cognitive processes (planning, monitoring,
analysis, etc., until met)
4. Produces ill effects that go beyond temporary distress
(needs are stronger than wants)
5. Can be satisfied by substitution and satiation
6. Is universal (seen in all humans in all situations)
7. Not derived from some more basic need
8. Influential (“affects a wide and diverse assortment of
behaviors”)
9. Influences more than just psychology, but also has
historical, sociological, & economic influence
44. Leary’s sociometer theory: self-esteem warns of
possible exclusion
Self-esteem is not the evaluation of
your worth—it is an indicator of how
well you are accepted into social
groups
Mark Leary:
We need to
think about
ourselves
occasionally,
but none of us
needs to think
about
ourselves as
much as we do.

47. Individualism Collectivism
A tradition,
ideology, or
personal outlook
that emphasizes
the primacy of the
individual and his
or her rights,
independence, and
relationships with
other
A tradition,
ideology, or
personal
orientation that
emphasizes the
primacy of the
group or
community rather
than each
individual person.

48. Copyright 2004 by Donelson R. Forsyth
The individual is primary, first. His
or her rights must be recognized and
put above the right of the group as a
whole. If the group’s goals aren’t
compatible with the individual’s goals,
then the individual is free to go his
or her own way.

The group is primary,
first. Its rights must be

put above the right of the
individual. The individual
belongs to the group.

Social Identity
Social Identity Theory:
Basics
• Basic assumption: the self-
concept is determined by group
memberships
• Personal identity (individual
self) and Social identity
(collective self)
• Tajfel & Turner’s minimal
intergroup situation
• Key processes: categorization
and identification
56. Social categorization:
Individuals automatically
classify people, including
themselves, into groups.
Social identification:
accepting as self-
descriptive (self-
stereotyping) the qualities
attributed to one’s group
(depersonalization)
Social Identity Theory
I am a member
of group X
People in group
X have qualities
A, B, and C

58. Self-esteem depends on an individual’s personal qualities
and the value of the groups to which they belong
Collective Self-esteem
59. Ingroup-outgroup bias: Rating one’s own group more positively
than other groups.
Basking in Reflected Glory (BIRG): stressing association with
successful groups.
Social creativity: Restricting comparisons between the ingroup
and other groups to stress the ingroup’s relative strengths
Stereotype threat: Anxiety-provoking (and self-confirming)
belief that others’ are biased against one’s group
Social mobility: Leaving the group
