Personality
Copyright 2004 - Prentice Hall
11-2
Analyzing Personality
• Psychologists define personality as a
stable pattern of thinking, feeling, and
behaving that distinguishes one person
from another.
• Two important components of this
definition are distinctiveness and relative
consistency.

11-3
Analyzing Personality
• Among the widely used
self-report inventories of
personality are the
Minnesota Multiphasic
Personality Inventory
(MMPI) and the
California Psychological
Inventory (CPI).
Copyright 2004 - Prentice Hall
11-4
Analyzing Personality
• The MMPI was designed to help diagnose
psychological disorders.
• The CPI is used to assess personality in
the normal population.

11-5
Analyzing Personality
• Projective tests use ambiguous stimuli and
require a great deal of interpretation by the
test administrator.
Copyright 2004 - Prentice Hall
11-6
Analyzing Personality
• The most frequently
used projective test is
the Rorschach inkblot
test.

11-7
Analyzing Personality
• The Barnum effect is the acceptance of
generalized personality descriptions.
• The effect results from the use of
favorable personality descriptions that
apply to many people.

11-8
Analyzing Personality
• Critics of the concept of consistency in
behavior argue that behavior is controlled
by situations.
• In defense of the idea of consistency,
some researchers note that there are
some problems with the methods used
and the assumptions made in this
research.

11-9
Analyzing Personality
• Seymour Epstein proposes that both sides
of the consistency issue are correct:
– Situations control behavior in a given
instance, and broad consistencies do exist.
– Consistencies become visible when we add
behaviors together, an approach termed
aggregation.

11-10
Trait Approaches
• Traits are summary terms that describe
tendencies to act and interact in particular
ways that are consistent across situations.
• Gordon Allport developed a list of trait
terms.
Copyright 2004 - Prentice Hall
11-11
Trait Approaches
• Raymond Cattell
proposed 16 source
traits to describe
personality and make
predictions of future
behaviors.
Copyright 2004 - Prentice Hall
11-12
Trait Approaches
• Hans Eysenck proposed the existence of
three major traits.
• Extraversion has been associated with a
number of differences in everyday
behavior.
Copyright 2004 - Prentice Hall
11-13
Trait Approaches
• Current research offers a model of five
major traits that seem to be relatively
stable across the life span and across
cultures.

11-14
Biological Factors in Personality
• Efforts to connect personality to biological
factors can be traced to Hippocrates’
theory of "humors" and later to phrenology.
Copyright 2004 - Prentice Hall
11-15
Biological Factors in Personality
• William Sheldon suggested a relationship
between body type and personality.
• Subsequent research demonstrated that
his findings were influenced by his
preconceptions.
Copyright 2004 - Prentice Hall
11-16
Biological Factors in Personality
• Additional support for the belief that
biological factors influence personality is
found in the negative correlation between
sensation-seeking scores and levels of the
enzyme MAO.

11-17
Biological Factors in Personality
• The study of identical twins reared apart
allows researchers to identify the effects of
heredity independently of the influence of
environmental factors.
• Evidence from such studies indicates that
heredity plays a role in a wide range of
personality characteristics as evidenced
by heritability estimates between 20 and
50%.

Biological Factors in Personality
• Recent evidence suggests that nonshared experiences exert a major
influence on the personality of siblings.

11-20
The Psychodynamic Perspective
• Freud suggested that behaviors, feelings,
and thoughts result from past events.
• Because this psychic determinism occurs
at an unconscious level, we are often
unaware of the true reasons for our
behavior.
Copyright 2004 - Prentice Hall
11-21
The Psychodynamic Perspective
• Freud compared the mind to an iceberg,
with three levels of consciousness
(conscious, preconscious, and
unconscious) and three structures
(Id, ego, and superego).
Copyright 2004 - Prentice Hall
11-22
The Psychodynamic Perspective
Copyright 2004 - Prentice Hall
11-23
The Psychodynamic Perspective
• Conflicts among the structures of the mind
occur beneath the level of conscious
awareness.
Copyright 2004 - Prentice Hall
11-24
The Psychodynamic Perspective
• Severe unconscious conflict produces
anxiety or guilt that warn the ego.
• The ego uses defense mechanisms to
protect itself from being overwhelmed by
anxiety or guilt.
Copyright 2004 - Prentice Hall
11-25
The Psychodynamic Perspective
• According to Freud, at different stages of
development the id centers its pleasureseeking behavior on different parts of the
body, called erogenous zones.
• The resulting psychosexual stages begin
with the oral stage and continue through
the anal and phallic stages.
Copyright 2004 - Prentice Hall
11-26
The Psychodynamic Perspective
• The Oedipal and Electra complexes occur
during the phallic stage.
• This stage is followed by the latency stage
and then by the genital stage and the
emergence of adult sexual desires.
Copyright 2004 - Prentice Hall
11-27
The Psychodynamic Perspective
• The neo-Freudians-including Jung,
Horney, and Adler disagreed with a
number of Freud's views (for example,
those emphasizing the sexual and
unconscious roots of behavior).
Copyright 2004 - Prentice Hall
11-28
The Psychodynamic Perspective
• Freud is credited with pointing out the
influence of early childhood experiences
and with developing a stage theory of
development
• In addition, he noted the potential
importance of unconscious experiences
and the influence of sexuality on human
behavior.
Copyright 2004 - Prentice Hall
11-29
The Psychodynamic Perspective
• Critics of psychodynamic theory note that Freud
based his ideas on small, unrepresentative
samples of disturbed individuals.
• Additionally, many of his concepts and principles
are not directly testable; hence, there is little
scientific evidence to support his theory.
• His subjective method of data collection and
views about women also have attracted
criticism.
Copyright 2004 - Prentice Hall
11-30
The Social-Cognitive Perspective
• Behavioral and learning psychologists
avoid commonly used terms such as traits.
• They explain the distinctiveness of a
person's behavior as resulting from unique
learning histories.
Copyright 2004 - Prentice Hall
11-31
The Social-Cognitive Perspective
• While acknowledging the importance of
learning, Julian Rotter and Albert Bandura
incorporated cognitive factors into their
theories of personality.
Copyright 2004 - Prentice Hall
11-32
The Social-Cognitive Perspective
• Rotter's social learning theory recognizes that
most reinforcers are social and that most
learning takes place in social situations.
• Expectancy about obtaining a reinforcer in a
given situation is an important cognitive variable.
• Individuals differ in the degree to which they see
themselves or chance ("fate") as responsible for
their successes and failures.
Copyright 2004 - Prentice Hall
11-33
The Social-Cognitive Perspective
• Measures of generalized expectancy,
known as locus of control, are related to a
variety of outcomes, including academic
and health behaviors.
Copyright 2004 - Prentice Hall
11-34
The Social-Cognitive Perspective
• According to Albert Bandura, individuals
not only are affected by the environment
but also can influence it.
• What's more, cognitive factors can
influence the person's behavior and his or
her environment.
Copyright 2004 - Prentice Hall
11-35
The Social-Cognitive Perspective
• This combination of
cognitive, behavioral,
and environmental
effects is called
reciprocal
determinism.
Copyright 2004 - Prentice Hall
11-36
The Social-Cognitive Perspective
• Self-efficacy is a person's judgment about
his or her ability to succeed in a given
situation.
• Unlike a trait, self-efficacy is specific to the
situation and can change over time.
Copyright 2004 - Prentice Hall
11-37
The Humanistic Perspective
• Humanistic approaches evolved in
opposition to the behavioral and
psychodynamic perspectives.
• They propose that human beings are
basically good and are directed toward
development and growth.
Copyright 2004 - Prentice Hall
11-38
The Humanistic Perspective
• Abraham Maslow's hierarchy of needs
begins with deficiency needs and leads to
self-actualization at the top.
• The power of deficiency needs keeps most
people from reaching the level of self actualization, which Maslow defines as
doing the best that an individual is capable
of doing.
Copyright 2004 - Prentice Hall
11-39
The Humanistic Perspective
• On the basis of his work with disturbed people,
Carl Rogers concluded that efforts to achieve
personal fulfillment were being stifled.
• He proposed that people's self-concepts had
become distorted by conditions of worth
imposed from the outside.
• In his theory, healthy individuals have a real selfconcept that is consistent with their ideal selfconcept
