It has a natural basis. If we can find the cause, we can find the cure.' 11 • General Paresis (Syphilis) and 10 biological link with madness – Associated with several unusual psychological and behavioural symptoms – Pasteur (below) discovered cause: a bacterial microorganism – Led to penicillin as successful treatment – Bolstered view that mental illness = physical illness and should be treated as such • John Grey, Dorothea Dix, and the Reformers (+1) DEVELOPMENT OF BIOLOGICAL TREATMENTS 12 (PP. 14-15) • Mental Illness = Physical Illness • 1930’s: Biological treatments standard practice – Insulin shock therapy, ECT (top), and brain surgery (i.e., lobotomy) • By 1950’s several medications established – Include neuroleptics such as reserpine (plant-based, right), major tranquilizers 2 PSYCHOLOGICAL TRADITION 13 (PP. 15-17) • Moral therapy – Allow institutionalized patients to be treated as normal as possible and to encourage and reinforce social interaction – Philippe Pinel and Jean-Baptiste Pussin – William Tuke followed Pinel’s lead in England – Benjamin Rush led reforms in USA – Clarence Hinks was mental health reformer and crusader in Canada • Reasons for falling out of moral therapy – Emergence of competing alternative psychological models • Rise of Moral Therapy – Treat institutionalized patients as normal as possible; encourage and reinforce social interaction – Philippe Pinel (right image) and Jean-Baptiste Pussin – William Tuke followed Pinel’s lead in England – Benjamin Rush led reforms in United States – Clarence Hinks was mental health reformer and crusader in Canada. THE 14 PSYCHOLOGICAL TRADITION (PP. 15-17) • Reasons for falling out of moral therapy – Emergence of competing alternative psychological models PSYCHOANALYTIC THEORY 15 (PP.17-21) 16 Freudian Theory • Freudian theory of structure and function of mind • Mind’s Structure (+1) – Id: pleasure principle; illogical, emotional, irrational – Ego: reality principle; logical and rational – Superego: moral principles; keeps Id and Ego in balance • Defense mechanisms • When Ego loses battle with Id and Superego – Displacement and denial – Rationalization and reaction formation – Projection, repression, and sublimation • Freudian Stages of Psychosexual Development – Oral, Anal, Phallic, Latency, and Genital stages NEO-FREUDIAN DEVELOPMENTS IN PSYCHOANALYTIC THOUGHT 17 (PP.21) • Anna Freud and self-psychology – Emphasized influence of ego in defining behaviour • Melanie Klein, Otto Kernberg, and object relations theory – Emphasized how children incorporate (introject) objects – Examples include images, memories, and values of significant others (objects) • Others developed concepts different from those of Freud – Carl Jung, Alfred Adler, Karen Horney, Erich Fromm, and Erik Erickson • Neo-Freudians generally de-emphasized sexual core of Freud’s theory • Unearth hidden intrapsychic conflicts (“the real problems”) • Therapy often long term • Techniques: 18 PSYCHOANALYTIC THERAPY (P.21-23) – Free association – Dream analysis • Examined transference and counter-transference issues • Little evidence for efficacy 3 HUMANISTIC THEORY 19 (PP. 21-22) • Carl Rogers, Abraham Maslow, and Fritz Perls • Major Theme – People are basically good – Humans strive toward selfactualization • Treatment – Therapist conveys empathy and unconditional positive regard – Minimal therapist interpretation • No strong evidence that humanistic therapies work BEHAVIOURAL MODEL (PP.23-25) • Derived from scientific approach to study of psychopathology 20 • Classical Conditioning: Ivan Pavlov (left image), John B. Watson – Ubiquitous form of learning – Conditioning involves correlation between neutral stimuli and unconditioned stimuli (+1) – Extended to acquisition of fear (Albert +1) • Operant Conditioning: Edward Thorndike, B. F. Skinner – Another ubiquitous form of learning – Most voluntary behaviour controlled by consequences that follow behavior – Reinforcement and Punishment • Both traditions greatly influenced development of behaviour therapy 21 22 CLASSICAL OPERANT CONDITIONING CONDITIONING Video BEGINNINGS OF BEHAVIOUR THERAPY (PP. 25-27) • Reactionary movement against psychoanalysis and non-scientific approaches • Early Pioneers – Joseph Wolpe: Systematic desensitization • For treatment of phobias (e.g., snakes) – Arnold Lazarus: Multi-modal behaviour therapy – Hans Eysenck: Conditioning therapy – Aaron Beck: Cognitive therapy – Albert Bandura: Social learning or cognitive-behaviour therapy – Stanley Rachman: an original founder of behaviour therapy • Behaviour therapy tends to be time-limited and direct • Strong evidence supporting efficacy of behaviour therapy 23 COGNITIVE PSYCHOLOGY 24 (NOT IN TEXT) • Reaction to behaviorist denial of role for mental processes, BUT believed in scientific study rather than subjective approaches (e.g., introspection) • Adoption of Information Processing Model (+1) and later Connectionist / Neural Network models (e.g., early Freud model & Lang model for phobia +2) • Number of cognitive processes hypothesized to contribute to psychopathology – Selective Attention: people with certain psychological disorders more sensitive to stimuli related to their disorder (e.g., depressed people more attuned to depressive stimuli +3) –… 4 INFORMATION PROCESSING MODEL 25 26 Freud “connectionist” model Lang (1979) Reaction Time (ms) Sad Dog Unhappy Table Crying Knife … … 27 PRESENT: SCIENTIFIC METHOD AND AN INTEGRATIVE APPROACH 28 (PP. 27) • Psychopathology multiply determined • One-dimensional accounts incomplete • Must consider reciprocal relations between Depression Words – Biological, Psychological, Social, and Experiential factors • Defining abnormal behaviour is also complex, and multifaceted, and has evolved • Supernatural tradition has no place in science of abnormal behaviour • Many practitioners and laypeople “treat” people with psychological disorders (+1 +2) NonDepressed Words Diverse people deal with clients / patients • Psychologists – Ph.D.’s: Clinical and counseling psychologists – Psy.D.’s: Clinical and counseling “Doctors of Psychology” – In Canada, regulation of profession of psychologist is under jurisdiction of provinces and territories. • Other Mental Health Professionals and Lay Practitioners – M.D.’s: Psychiatrists – M.S.W.’s: Psychiatric and non-psychiatric social workers – MN/MSN’s: Psychiatric nurses – Lay public and community groups 29 Mental Health Professionals 30 MD PhD PsyD MA • Number of some practitioners in Canada (+1) 5 DIMENSIONS OF SCIENTISTPRACTITIONER MODEL (P. 7-8) 31 • Psychologists (somewhat) united by ScientistPractitioner Framework • Three Dimensions SCIENTIST-PRACTITIONERS 32 (PP. 7-8) • Three Major Goals of Psychological Research – Producers of research – Consumers of research – Evaluate their work using Empirical methods • Begin with presenting problem • Distinguish clinically significant dysfunction from common human experiences • Describe Incidence and Prevalence of disorders • Describe onset of disorders – Acute vs. Insidious onset • Describe course of disorders – Episodic, Time-limited, or Chronic course CLINICAL DESCRIPTION (PP. 8) 33 CAUSATION, TREATMENT, AND OUTCOME IN PSYCHOPATHOLOGY 34 (PP. 8) • Etiology or Causation: What factors contribute to development of psychopathology? • Treatment: How to best improve lives of people suffering from psychopathology? – Treatment development: includes Pharmacologic, Psychosocial, and / or Combined treatments • Outcome: How do we know that we have alleviated psychological suffering? – Evaluate efficacy (effectiveness) of treatments – Challenging because of many confounding factors 6
