Introduction to Psychology
Personality
Psychodynamic Views of Personality
• Freud invoked a role of unconscious
processes in the control of behavior
– Based on his observations of clients
• Topographical model: argued for 3
levels of consciousness
– Conflict occurs between the different
aspects of consciousness
– Requires compromise formation
– Id, ego, superego
Freud’s Developmental Model
• Human behavior is motivated by two drives
– Aggressive
– Sexual
• Libido refers to pleasure-seeking and sensuality as
well as desire for intercourse
• Libido follows a developmental course
during childhood
– Stages of development
– Fixed progression of change from stage to stage
– Notion of fixation at a particular libidinal stage

Ego Defense Mechanisms
• Defense mechanisms are unconscious mental
processes that protect the conscious person
from anxiety
– Repression: anxiety-evoking thoughts are kept
unconscious
- Denial: person refuses to recognize reality
- Projection: person attributes their own
unacceptable impulses to others
Ego Defense Mechanisms
– Reaction Formation: person converts an
unacceptable impulse into the opposite impulse
– Sublimation: person converts an unacceptable
impulse into a socially acceptable activity
– Rationalization: person explains away their
actions to reduce anxiety
– Displacement: diverting emotional feelings from
their original source to a substitute target
Projective Tests
• Projective tests
assume that persons
presented with a
vague stimulus will
“project” their own
impulses and desires
into a description of
the stimulus
• Rorschach Inkblots
• Thematic
Apperception Test
"I see a …..”

Evaluation of Freud’s Contributions
to Personality Theory
• Contributions
– Emphasis on unconscious processes
– Identification of defense mechanisms
– Importance of childhood experiences in shaping adult
personality
• Limitations
– Theories are not solidly based on scientific observation
– Excessive emphasis on drives such as sex and aggression
B.F. Skinner (1904-1990):
Radical Behaviorism
• scientific analysis of behavior
• personality
a collection of behavior patterns
• black box theory
• explanatory fictions (e.g., freedom, “the self”)
Albert Bandura’s
Social Learning Theory
Observational (Vicarious) Learning
• people learn by merely observing what others do
and what happens to them
• two processes:
– acquisition
– acceptance/performance
• consequences are an important influence
RECIPROCAL DETERMINISM
PERSON
(cognitions, expectations)
BEHAVIOUR
ENVIRONMENT
(contingencies)
Albert Ellis:
Rational Emotive Therapy (RET)
• Assumes that all humans have fundamental goals,
purposes and values (e.g., stay alive, be satisfied)
• if people choose to stay alive & try to be
happy/satisfied they are acting “rationally”
• when people think/emote/behave in a way that
interferes with these goals, they act “irrationally”
Evaluation of Cognitive-Social
Personality Theory
• Contributions
– Provided emphasis on the role of thought and
memory in personality
• Limitations
– Overemphasis of rational side of personality
– Avoidance of explanations of unconscious
processes in personality
Humanistic Personality
Approaches
• Humanistic personality theorists reject the
behaviorist and psychodynamic notions of
personality
• Humanists emphasize the notion that each
person has a potential for creative growth
• The intent is to assist the person in
developing to their maximal potential
Roger’s Person-Centered Approach
• Rogers believed that humans are good by nature
(in contrast to psychodynamic view of human
nature)
• Rogers emphasized the notion of self-concept
• Each person has multiple selves:
– True-self: the core aspect of being
– False-self: the self that is created by distortions from
interpersonal experiences
– Ideal-self: what the person would like to be
Evaluation of Humanistic
Personality Theory
• Contributions
– Focus on how humans strive to determine the
meaning of life
• Limitations
– Humanistic approach is not a complete
theoretical account of personality
– The approach has not generated a body of
testable hypotheses and research
Trait Approach
TRAIT: Consistent patterns of thoughts, feelings, or
actions that distinguish people.
•
•
•
•
•
•
•
ASSUMPTION 1: traits are stable over time
ASSUMPTION 2: traits are stable across situations
people differ on continuous variables or dimensions
traits exist on a continuum
basic differences between people are quantitative
traits are used to understand and predict behaviour
emphasizes measurement of traits through tests
The Big Five Factors of Personality

Openness to experience
Conscientiousness

Genetics of Personality
• Biological relatives are more similar in
personality than are strangers
• Twins raised together and raised apart
provide evidence for a genetic aspect of
personality
