imbalances

Link With Madness
– Several unusual psychological and
behavioral symptoms
– Pasteur discovered the cause – A bacterial
microorganism
– Led to penicillin as a successful treatment

Psychological Models
Psychoanalytic Theory
• Freudian Theory of the Structure and
Function of the Mind
• Structure of the Mind
– Id (pleasure principle; illogical, emotional,
irrational)
– Ego (reality principle; logical and rational)
– Superego (moral principles; keeps Id and
Ego in balance)
Psychoanalytic Theory (continued)

with the Id and Superego
– Displacement & denial
– Rationalization & reaction formation
– Projection, repression, and sublimation
• Psychosexual Stages of Development
– Oral, anal, phallic, latency, and genital
stages
Later Developments in Psychoanalytic
Thought
• Anna Freud and Self-Psychology

defining behavior
• Melanie Klein, Otto Kernberg, and Object
Relations Theory
– Emphasized how children incorporate
(introject) objects
– Objects – images, memories, and values of
significant others
Later Developments in Psychoanalytic
Thought (continued)

Freudian Thought

theory
– Jung, Adler, Horney, Fromm, and Erickson
Psychoanalytic Psychotherapy: The
“Talking” Cure
• Unearth the Hidden Intrapsychic Conflicts
– “The Real Problems”
• Therapy Is Often Long Term
• Techniques
– Free Association
– Dream Analysis
• Examine Transference and CounterTransference Issues
• Little Evidence for Efficacy
Humanistic Theory
• Major Players
– Abraham Maslow and Carl Rogers
• Major Themes
– That people are basically good
– Humans strive toward self-actualization
Humanistic Theory (continued)
• Humanistic Therapy
– Therapist conveys empathy and
unconditional positive regard
– Minimal therapist interpretation
• No strong evidence that humanistic therapies
work
The Behavioral Model
• Derived from a Scientific Approach to the
Study of Psychopathology
• Classical Conditioning (Pavlov; Watson)
– Ubiquitous form of learning
– Contingency between neutral and
unconditioned stimuli
– Conditioning was extended to the
acquisition of fear
The Beginnings of Behavior Therapy
• Challenged Psychoanalysis and NonScientific Approaches
• Early Pioneers
– Joseph Wolpe – Systematic desensitization
• Operant Conditioning (Thorndike; Skinner)
– Another ubiquitous form of learning
– Voluntary behavior is controlled by
consequences
The Beginnings of Behavior Therapy
(continued)
• Learning Traditions Influenced the
Development of Behavior Therapy
– Behavior therapy tends to be time-limited
and direct
– Strong evidence supporting the efficacy of
behavior therapies
The Present: An Integrative Approach
• Psychopathology Is Multiply Determined
• Unidimensional Accounts of Psychopathology
Are Incomplete
The Present: An Integrative Approach
(continued)
• Must Consider Reciprocal Relations Between
– Biological, psychological, social, and
experiential factors
• Defining Abnormal Behavior
– Complex, multifaceted, and has evolved
• The Supernatural Tradition
– Has no place in a science of abnormal
behavior
