What is a psychological disorder?
- •Psychological
- dysfunction
- –Breakdown in cognitive, emotional, or behavioral
- functioning*
–Difficulty performing appropriate and expected roles
- –Impairment is set in the context of a person’s
- background
- •Atypical
- or not culturally expected response
–Reaction is outside cultural norms
-
•TheDiagnostic and Statistical Manual (DSM-IV-TR)
- –Prototypes (listed as criteria) for various mental
- disorders
-
Psychopathology
- •Scientific
- study of psychological disorders
- •Mental
- health professionals
–Clinical and counseling psychologists
–Psychiatrists
–Psychiatric (or non-psychiatric) social workers

Etiology
What contributes to the development of psychopathology
-
Treatment
development
–How can we help alleviate psychological suffering?
- –Includes pharmacologic, psychosocial, and/or combined
- treatments
-
Treatment
outcome research
–How do we know that we have helped?
–Limited in specifying actual causes of disorders
-
The Supernatural Tradition
- •Deviant
- behavior as a battle of
- “Good” vs. Evil
–Caused by demonic possession, witchcraft, sorcery
- –Treatments included exorcism, torture, beatings, and
- crude surgeries
- •Deviant
- behavior caused by other phenomena—magnetic fields, moons, stars
-
The Biological Tradition
- •Mental
- disorders attributed to disease or biochemical imbalances
- –Hippocrates: mental diseases can be treated like any
- other disease
–Galen: “Humoral theory of mental illness”
- –General paresis (syphilis) and the
- biological link with madness
–John Grey: more humane treatment
-
The
Psychological Tradition
- •Abnormal
- behavior is attributed to faulty psychological development and to social
- context
- •The
- rise of moral therapy
–More humane treatment of institutionalized patients
–Encouraged and reinforced social interaction
–Asylum reform and mental hygiene movement
–Emergence of competing alternative psychological models
-
Psychoanalytic
Theory
- •Freudian
- theory of the structure and function of the mind
- –Id (pleasure principle; illogical, emotional,
- irrational)
–Ego (reality principle; logical and rational)
–Superego (moral principles)
-
Psychoanalytic
Theory
- •Defense
- mechanisms: unconscious protective processes to keep emotions in check
–e.g., displacement, denial,
- •Psychosexual
- stages of development
–Oral, anal, phallic, latency, and genital stages
- –Distinct patterns of gratifying our basic needs and
- satisfying our drive for physical pleasure
-
Later
Developments in
Psychoanalytic Thought
- •Anna
- Freud and ego/self-psychology
- –Emphasized influence of the ego in the development of
- psychological disorders
•The“neo-Freudians”: Departures from Freudian thought
–De-emphasized the sexual core of Freud’s theory
–Jung, Adler, Horney, Fromm, and Erikson
- •Melanie
- Klein, Otto Kernberg, and object
- relations theory
–Emphasized how children incorporate (introject) objects
- –Objects – images, memories, and values of significant
- others
-
Psychoanalytic
Psychotherapy: The “Talking” Cure
- •Unearth
- the hidden intrapsychic conflicts or “the
- real problems”
- •Therapy
- is often long term
•Techniques
–Free association
–Dream analysis
- •Examine
- transference and counter-transference issues
- •Little
- evidence for efficacy
-
Humanistic
Theory
•Theme:
–People are basically good
–People are striving towards self-actualization
- •Focus
- on human potential and self-actualizing
–Maslow: hierarchy of needs
- –Rogers: client/person-centered therapy; unconditional
- positive regard
- •No
- strong evidence that humanistic therapies work (not enough research)
-
The
Behavioral Model
- •Also
- known as Cognitive-Behavioral Model or Social Learning Model
- •Derived
- from a scientific approach to the study of psychopathology
- •Challenged
- psychoanalysis and
- non-scientific approaches
-
Behavior
Therapy
- •Classical
- conditioning (Pavlov; Watson)
–Contingency between neutral and unconditioned stimuli
–Food (UCS) à Salivation (UCR)
- –Tone (CS) Food
- (UCS) à Salivation (UCR)
–Tone (CS) à Salivation (CR)
- –Conditioning was extended to the acquisition of and
- elimination of fear
- à Systematic
- desensitization
- •Operant
- conditioning (Thorndike; Skinner)
- –Voluntary behavior is controlled by consequences
- –Increase behavior (reinforcement)
- –Shaping (complex tasks)
- •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
- •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
-
One-Dimensional Models
•Explain behavior in terms of a single cause
•Tend to ignore information from other areas
•Biological
•Psychodynamic
•Cognitive-behavioral
•Humanistic
-
Multidimensional Models
–Interdisciplinary, eclectic, and integrative
–“System” of influences that cause and maintain suffering
–Draw upon information from several sources
–Abnormal behavior results from multiple influences
-
Multidimensional Models of
Abnormal Behavior
•Major Influences
–Biological
–Behavioral
–Emotional
–Social & cultural
–Developmental
•Equifinality
–Many routes to same destination/disorder
•Multifinality
–Same event can lead to different outcomes
-
Genetic contributions to psychopathology
•Genotype vs. phenotype
- •Genes: long molecules of deoxyribonucleic acid
- (DNA)—double helix structure
–Provide boundaries to our development
–23 pairs of chromosomes
–Dominant vs. recessive genes
•Development & behavior is often polygenetic
•Genetic contribution to psychopathology
–Less than 50%
-
•Reciprocal gene-environment model
–Examples: depression
•Epigenetics
–Genes are not the whole story
–Environmental influences may override/turn on genetics
–Complex relationship between genes and environment
–
-
•The central nervous system (CNS)
•Brain and spinal cord
•Processes information received from our sense organs
-
•The peripheral nervous system (PNS)
•Somatic and autonomic branches
- •Control muscles (and somatic—conveys sensory information
- to CNS)
-
Structure of the Brain
•Two main parts
–Brainstem and forebrain
•Three main divisions
–Hindbrain
–Midbrain
–Forebrain
-
•Hindbrain
–Medulla – heart rate, blood pressure, respiration
–Pons – regulates sleep stages
–Cerebellum – involved in physical coordination
-
•Midbrain
–Coordinates movement with sensory input
–Contains parts of the reticular activating system (RAS)
-
•Forebrain
- •Most
- sensory, emotional, and cognitive processing
-
•Limbic system
–Regulation of emotion and basic learning processes
–Variety of different brain structures
•Thalamus
Hypothalamus
-
•Cerebral Cortex
–Gives us our distinctly human qualities
–2 Hemispheres
–Lateralized brain functions
-
Peripheral Nervous Systems (PNS)
- •Coordinates with brain stem to make sure body is working
- properly

–Dopamine
-
Glutamate
–Most common
–Excitatory transmitter
-
GABA= Gamma-aminobutyric acid
–Major inhibitory neurotransmitter in brain
–Reduces anxiety
–Reduces overall arousal
-
Serotonin
•5-hydroxytryptamine (5HT)
•6 major 5HT circuits in brain
•Regulates behavior, mood, thought processes
- –Low levels: vulnerable to be less inhibited, more
- impulsive
•Drugs that affect 5HT system
–Tricyclic antidepressants
–SSRIs
–St. John’s Wort
-
Norepinephrine
•Also called noradrenaline
- •Important for attentiveness, emotions, sleeping,
- dreaming and learning
- •Also released into blood as hormoneà
- contractions of blood vessels and increased heart rate
•Stimulates 2 groups of receptors
–Alpha adrenergic
–Beta adrenergic
•Beta blockers
-
Dopamine
- •General effect of turning on various brain circuits
- associated with certain types of behavior
•Helps control brain’s reward and pleasure centers
•Regulates movement and emotional responses
•Implicated in:
–Schizophrenia
–Addiction
–Depression
–ADHD
–Parkinson’s disease
-
Implications of Neuroscience
for Psychopathology
•Relations between brain and abnormal behavior
–Obsessive Compulsive Disorder (OCD)
•Effects of therapy
- –Change brain structure & function; “re-wire
- the brain”
–Baxter et al. (1992)
- •Brain imaging of patients with OCD; after treatment,
- brain circuit had been changed
•Psychosocial factors
- –Rats in rich environment vs. “couch
- potatoes”
–Stress in early development
-
The Contributions of Cognitive Science
•Conditioning and cognitive processes
•Classical and operant conditioning
•Social learning

–To elicit or evoke action
•Components of emotion
–Physiological
–Cognitive
–Behavioral
–Subjective experience
–Example of fear
-
•Cultural factors

-
•Gender effects
–Gender roles
–Response to stress also different
-
•Social effects on health and behavior
–Frequency and quality important

–
-
•Multiple causation
The rule, not the exception
-
•Take a broad, comprehensive, systemic perspective
–Biological
–Psychological
–Social, cultural, and developmental factors
-
•Comprehensive approach
–Understanding the causes of psychopathology
–To best alleviate and prevent psychopathology

Overview and defining featuresSymptoms are milder than major depressionPersists for at least two yearsNo more than two months symptom freeSymptoms can persist unchanged over long periods (≥ 20 years)Facts and statisticsLate onset – typically in the early 20s
-
Double Depression:
An Overview
- Overview
- and defining features
- ◦Major
- depressive episodes and dysthymic disorder
- ◦Dysthymic disorder
- often develops first
- ◦Associated
- with severe psychopathology
- ◦Associated
- with a problematic future course
-
Stress and Unipolar
Depression
- Stress
- can trigger depressive episode.
- Poorer
- response to tx if stress. Longer time to remission.
- Depressed
- people report experiencing more stressful life events.
-
Biological Model of Depression
- ◦Low
- activity of norepinephrine and serotonin
- ◦Interaction
- b/w norepinephrine and
- serotonin, and w/ other neurotransmitters
- More
- melatonin
- Brain
- anatomy and brain circuits
◦Hippocampus
- Reduced neurogenesis; reduced
- size
◦Amygdala
- Greater
- activity and blood flow
◦Broadmann Area 25
Under cingulate cortex
- Smaller
- in depressed patients; more active with depression
-
Biological Treatments for Depression
Antidepressants
- ◦Monoamine oxidase (MAO)
- inhibitors
- Slow body’s production of enzyme “monoamine
- oxidase” (MAO)
