This document summarizes key concepts from Chapter 3 on perception and attribution. [1] It defines perception as how people select, organize, interpret, and respond to information from their environment. [2] The perceptual process involves observation, selection, organization, interpretation, and response. [3] Common perceptual errors discussed include stereotyping, halo effect, projection, and expectancy effects.

2. Perception
Definition: The process by which people select,
organize, interpret, and respond to information
from the world around them.
Perception (consciously and unconsciously) involves
searching for, obtaining, and processing information in
the mind in an attempt to make sense of the world
Selection and organization often account for
differences in interpretation/perception between
individuals observing the same stimuli

* External factors
Organization
* Internal factors

4. Concepts Manifest in the Princeton Case
Selective Screening: the process by which people filter
out most information so they can deal with the most
important matters
Perceptual Set: an expectation of a perception based on
past experience with the same or similar objects
Pollyanna Principle: the notion that pleasant stimuli are
processed more efficiently and accurately than unpleasant
stimuli; an effect of motivation on perception
Perceptual Grouping: tendency to form individual stimuli
into a meaningful pattern by continuity, closure, proximity,
or similarity

5. Person Perception
Definition: the process by which individuals
attribute characteristics or traits to other people;
closely related to attribution
Implicit personality theories: personal beliefs
about the relationships among other’s physical
characteristics, personality traits, and specific
behaviors
Impression Management: the attempt people
make to manipulate or control the impressions
others form about them

6. Common Perceptual Errors
Perceptual defense: the tendency for people to protect
themselves against ideas, objects, or situations that are
threatening
Stereotyping: the tendency to assign attributes to someone
solely on the basis of the category of people, of which that
person is a member
Halo effect: the process by which the perceiver evaluates
another person solely on the basis of one attribute, either
favorable or unfavorable
Projection: the tendency for people to see their own traits in
others
Expectancy effects: extent to which expectations bias how
events, objects, and people are actually perceived
Self-fulfilling prophecy: expecting certain things to happen will
shape the behavior of the perceiver in such a way that the expected
is more likely to happen

7. Nature of the Attribution Process*
Definition: The ways in which people come to understand
the causes of their own and others’ behaviors
Most often an unconscious process (i.e., people are not
normally aware of making attributions)
People are constantly attributing the behavior of themselves
and others to either internal (i.e., personal) or external
(i.e., situational) causes.

8. The Attribution Process
Antecedents-- •Information
factors internal •Beliefs
to the perceiver •Motivation
•Perceived external
Attributions made by the perceiver or internal causes
of behavior
•Behavior
Consequences for the perceiver •Feelings
•Expectations

9. Theory of Causal Attributions
Consistency
s Does person usually Ye
Ye s
behave this way in
this situation?
Distinctiveness
External Attribution Does person behave Internal Attribution
No
(to person’s situation) Yes differently in different (to person’s disposition)
situations?
Consensus
Ye
s Do others behave No
similarly in this
situation?

10. Frequent Attribution Errors*
Fundamental Attribution Error = overestimating the
personal causes for other’s behavior while underestimating
the situational causes
Self-Serving Bias = attributing personal success to internal
factors and personal failure to external factors
