Social Development
• Psychodynamic approaches to personality:
personality is motivated by inner forces and
conflicts about which people have little
awareness and over which they have no
control
• Psychoanalytic theory: Sigmund Freud’s
theory that unconscious forces act as
determinants of personality

Social Development
• Unconscious: a part of the personality that
contains the memories, knowledge, beliefs,
feelings, urges, drives, and instincts of which
the individual is not aware; a “safe haven” for
memories of threatening events

The 3 Components of Personality
• The id: the raw, unorganized, inborn part of
personality; reduces tension created by
primitive drives related to hunger, sex,
aggression, and irrational impulses
– Operates on the pleasure principle: reduce
tension and maximize satisfaction

The 3 Components of Personality
• The ego: the part of personality that provides
a buffer between the id and the outside world
– Operates on the reality principle: instinctual
energy is restrained to keep individual safe and to
help integrate the person into society

The 3 Components of Personality
• The superego: the final component of
personality to develop, it represents the rights
and wrongs of society as handed down by a
person’s parents, teachers, and other
important people
– Includes the conscience: makes you feel guilty if
you do something morally wrong

Freud’s Psychosexual Stages
• Freud’s Psychosexual Stages: how personality
develops; individuals encounter conflicts
between the demands of society and their
own urges for pleasure
– Fixations: unresolved conflicts that persist beyond
the stage in which they first occur; come from
having needs ignored or being overindulged
during that stage
8

Freud’s Psychosexual Stages
• Oral stage (birth – 1 ½): infant’s center of pleasure is
the mouth; fixation may lead to adult who is
unusually interested in oral activities (eating, talking,
smoking)
• Anal stage (1 ½ - 3): child’s center of pleasure is the
anus; toilet training – pleasure comes from retaining
and expelling feces; fixation may lead to adult who is
unusually rigid, orderly, and punctual, or the
opposite
9

Freud’s Psychosexual Stages
• Phallic stage (3 – 6): child’s center of pleasure is the
genitals
– Oedipal conflict: a child’s unconscious sexual interest in
the opposite-sex parent, typically resolved by
identification with the same-sex parent (wanting to be like
that person; imitating his or her behavior and adopting
similar beliefs and values)
– Difficulties in phallic stage may lead to improper sex-role
behavior & failure to develop a conscience
10

Freud’s Psychosexual Stages
• Latency period (6 – adolescence): children’s sexual
concerns are temporarily put aside
• Genital stage (adolescence – adulthood): sexual
feelings reemerge; focus on mature, adult sexuality
(sexual intercourse)
11

Freud’s Psychosexual Stages
• Defense mechanisms: unconscious strategies
people use to reduce anxiety by concealing its
source from themselves and others
– Repression: primary defense mechanism, in which
unacceptable or unpleasant id impulses are
pushed back into the unconscious

Neo-Freudian Psychoanalysts
• Neo-Freudian psychoanalysts: psychoanalysts
who were trained in traditional Freudian
theory but who later rejected some of its
major points
• Collective unconscious: a common set of
ideas, feelings, images, and symbols that we
inherit from our ancestors, the whole human
race, and even animal ancestors (Carl Jung)
– Archetypes

Neo-Freudian Psychoanalysts
• Karen Horney’s perspective: championed women’s
issues; believed personality develops in the context
of social relationships & depends on the relationship
between parents and child
• Inferiority complex: feelings of inferiority in adults
that they developed as children, when they were
small and limited in their knowledge about the world
(Alfred Adler)

Trait Approaches
• Trait theory: seeks to identify basic traits
(consistent personality characteristics and
behaviors displayed in different situations)
necessary to describe personality
– Propose that all people possess certain traits, but
the degree varies and can be quantified
17

Learning Approaches
• Learning theories of personality emphasize
the external environment
– Skinner’s behaviorist approach: personality is a
collection of learned behavior patterns
– Social cognitive approaches: emphasize influence
of a person’s cognitions, as well as observation of
others’ behavior
• Self-efficacy
• Self-esteem
20

Biological & Evolutionary Approaches
• Biological and evolutionary approaches: the
important components of personality are
inherited
– Temperament: the basic, innate disposition that
emerges early in life
21
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Humanistic Approaches
• Humanistic approaches: emphasize people’s
innate goodness and desire to achieve higher
levels of functioning
– Self-actualization: a state of self-fulfillment in
which people realize their highest potential, each
in a unique way (Rogers and Maslow)
– Unconditional positive regard: an attitude of
acceptance and respect on the part of an
observer, no matter what a person says or does
22

Comparing Approaches to Personality
• No single approach is the best explanation of
personality
• No clear way to scientifically test the theories
against each other
• Personality can be viewed from a number of
perspectives simultaneously

Assessing Personality
• Learning Outcomes
– Discuss self-report measures of personality
– Define projective methods
– Explain behavioral assessment
24
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Assessing Personality
• Psychological tests: standard measures
designed to assess behavior objectively
– Reliability
– Validity
– Tests are based on norms: standards of test
performance that permit the comparison of one
person’s score with the scores of others who have
taken the same test
25
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Self-Report Measures of Personality
• Self-report measures: gathering data about
people by asking them questions about a
sample of their behavior
26
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Self-Report Measures of Personality
• Minnesota Multiphasic Personality
Inventory-2 (MMPI-2): a widely used selfreport test that identifies people with
psychological difficulties and can predict a
variety of other behaviors
• Test standardization: validates questions in
personality tests by studying the responses of
people with known diagnoses
27
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Projective Methods
• Projective personality tests: tests in which a
person is shown an ambiguous (unclear)
stimulus and asked to describe it or tell a story
about it
• Rorschach test: shows a series of symmetrical
visual stimuli; people are then asked what the
figures represent to them
28

Projective Methods
• Thematic Apperception Test (TAT): a series of
pictures about which a person is asked to
write a story
30

Behavioral Assessment
• Behavioral assessment: direct measures of an
individual’s behavior used to describe
personality characteristics
– May be carried out naturalistically, by observing
people in their own settings, or in the laboratory,
by observing people in controlled situations

Intelligence?
• Learning Outcomes
– Summarize the theories of intelligence
– Compare and contrast practical and emotional
intelligences
– Explain approaches to measuring intelligence
– Identify variations in intellectual ability
32

Theories of Intelligence
• g or g-factor: the single, general factor for
mental ability assumed to underlie
intelligence in some early theories
• Fluid intelligence: reflects informationprocessing capabilities, reasoning, and
memory
33
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Theories of Intelligence
• Crystallized intelligence: the accumulation of
information, skills, and strategies that are
learned through experience and can be
applied in problem-solving situations; reflects
our ability to call up information from longterm memory
34
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Theories of Intelligence
• Theory of multiple intelligences: proposes eight
spheres of intelligence, each relatively independent
of the others (Howard Gardner)
– musical, bodily kinesthetic, logical-mathematical,
linguistic, spatial, interpersonal, intrapersonal, and
naturalist
• Information-processing approach: the most
accurate measure of intelligence is provided by the
way people store material in memory and use that
material to solve intellectual tasks
35

Practical & Emotional Intelligence
• Practical intelligence: intelligence related to
overall success in living (Robert Sternberg)
• Emotional intelligence: the set of skills that
underlie the accurate assessment, evaluation,
expression, and regulation of emotions
36
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Assessing Intelligence
• Intelligence tests: tests devised to quantify a
person’s level of intelligence
– First tests developed by French psychologist
Alfred Binet
– Mental age: the average age of individuals who
achieve a particular level of performance on a test
– Chronological age: actual, physical age
37
© 2013 The McGraw-Hill Companies, Inc. All rights reserved.
Assessing Intelligence
• Intelligence quotient (IQ): a score that takes
into account an individual’s mental and
chronological ages
– IQ score = (MA/CA) x 100
– Deviation IQ scores: the way IQ scores are calculated
today; scores assigned to individuals based on the
difference between that score and the average score
for everyone of that age (average score would
translate to an IQ score of 100)
38

Assessing Intelligence
• Contemporary IQ tests
– Stanford-Binet Intelligence Scale: types of
questions are based on age
– Wechsler Adult Intelligence Scale-III (WAIS-III)
and Wechsler Intelligence Scale for Children-IV
(WISC-IV): divided into a verbal scale and
performance (non-verbal) scale

Variations in Intellectual Ability
• Intellectual disability (mental retardation): a
condition characterized by significant
limitations both in intellectual functioning and
in conceptual, social, and practical adaptive
skills
–

40
Mild intellectual retardation: IQ scores from 55-69
Moderate retardation: IQ scores from 40-54
Severe retardation: IQ scores from 25-39
Profound retardation: IQ scores below 25

Variations in Intellectual Ability
• Biological causes of intellectual disabilities
(almost 1/3 of cases)
– Fetal alcohol syndrome
– Down syndrome
• Familial retardation: no apparent biological
defect exists, but there is a history of retardation
in the family
41

Variations in Intellectual Ability
• Intellectually gifted: having an IQ score greater than
130 (about 2 – 4% of the population)
• Culture-fair IQ test: a test that does not discriminate
against the members of any minority group
• Intelligence shows a high degree of heritability (the
degree to which a characteristic is related to genetic,
inherited factors), but environmental factors play a
large role in influencing intelligence also
