3. Kurt Lewin’s Field Theory
Life space
◦ All internal and external forces, and their
relationships to one another
◦ e.g., family, religion, work, etc.
Contemporaneous causation
Behavior is caused at the moment of its
occurrence by all the forces acting at that moment
How affected you are by the environmental
forces and context of the situation is your
level of “field dependence”
field = the forces/context around you at a given
moment that can affect your behavior
See table 7.1 in textbook
4. Schema Theory
Schema
◦ A cognitive structure that organizes knowledge and
expectations about one’s environment
◦ Determines how we think and act
◦ Different experiences lead to different ways of
“seeing things”
◦ We may often expect others to share our schemas
Script
◦ Schemas for familiar events
◦ e.g., eating at a restaurant
◦ What if your dinner partner has a different script for this? They
eat pizza with a fork, don’t usually leave a tip, take 20 minutes to
choose something from the menu, and order dessert & coffee.
While you use your hands, always tips, make choices quickly, and
leave as soon as you are done eating.
5. Categorization
We tend to organize events, objects, and people
into categories
Positive effects of categorization
◦ Quickly understand complex information
◦ Make likely inferences about new things
Negative effects of categorization
◦ Stereotypes
◦ Overlook individuating characteristics
One of the first categories we tend to put people
into is gender, male or female.
When it is ambiguous, we feel uncomfortable and
confused because our normal categorization process
isn’t working and our scripts fail us
On the other hand, if we frequently came into contact
with gender ambiguity, we would develop a schema,
scripts, and a probably a different categorization process
9. Explanatory Style
A characteristic way of interpreting life events
Optimism and Pessimism
◦ Optimistic style is generally associated with better outcomes
◦ Implications for achievement
Learned Helplessness (Seligman)
◦ Repeated exposure to unavoidable punishment leads to the acceptance
of avoidable punishment
Cognitive intervention can reduce the
depressive effect of pessimism
Positive Psychology (Seligman)
◦ New ways of thinking can be trained
◦ Learned Optimism

11. Julian Rotter
Behavior potential
◦ Likelihood that a behavior will be performed in
a particular situation
Generalized vs. specific expectancies
◦ Generalized expectancies apply to categories of
behaviors and situations
General personality traits & behaviors
Ex. I don’t enjoy parties as a general rule because I
expect them to be dull and I get nervous talking to
new people
◦ Specific expectancies apply to particular
instances of behaviors and situations
Ex. I am looking forward to my best friend’s birthday
party
12. Julian Rotter
Six psychological needs
◦ Recognition-status
◦ Dominance
◦ Independence
◦ Protection-dependency
◦ Love and affection
◦ Physical comfort
Secondary reinforcers
◦ Associated with satisfaction of these needs
◦ Subjective value of reinforcers, depending on person
◦ Ex. A promotion at work gives me the ability to have a roof
over my head, eat, and meet basic biological needs (primary).
It also is important to me because I get more recognition at
work, can move into a bigger place to be more comfortable,
and get to be work more independently in my new job
(secondary). These are things I value, therefore I worked
hard to get the promotion.
