Psychological Disorders Syndromes marked by a significant disturbance in an individual’s cognition, emotion regulation, or behavior. Medical model: disorders are “sicknesses” with physical causes that can be cured through hospital treatment. Biopsychosocial model: disorders reflect both genetic predispositions and social influences.
DSM-5 Diagnostic and Statistical Manual of Mental Disorders, 5 th Edition: provides the diagnostic criteria used to classify psychological disorders. Pros: It provides a reliable way to guide medical diagnoses and treatment. Cons: Disorders are described by their symptoms instead of causes; labels can be subjective.
According to lecture, the Rosenhan study demonstrates that: A. Mental health diagnoses can be subjective and context dependent. B. The DSM is not an accurate tool for diagnosis. C. Symptoms of mental disorders vary significantly across people. D. Psychologists are more likely to have mental disorders.

Mood Disorders Disturbances in a person's mood and emotional state. The “common cold” of psychological disorders. Unipolar (e. g. major depressive disorder): experiencing extreme lows. Bipolar (e. g. manic-depressive disorder): fluctuating between extreme highs and extreme lows.
Major Depressive Disorder: Overview Diagnostic criteria: • Depressed mood; reduced interest or enjoyment. • Problems regulating appetite and sleep. • Feeling listless, worthless, hopeless, no energy. • Problems thinking, concentrating, making decisions.

Major Depressive Disorder: Biological Approach The presumed cause of depression is a chemical imbalance in the brain - underactive serotonin system. Implicated neurotransmitters: serotonin and norepinephrine. (NPR story says: not that much evidence. )
Tricyclics decrease depression by: A. Inhibiting the enzyme monoamine oxidase B. Partially blocking serotonin and norepinephrine reuptake C. Increasing endorphin production D. B & C
Tricyclics decrease depression by: A. Inhibiting the enzyme monoamine oxidase B. Partially blocking serotonin and norepinephrine reuptake C. Increasing endorphin production D. B & C
Major Depressive Disorder: Antidepressants MAO inhibitors (e. g. Nardil) - inhibit the enzyme monoamine oxidase from breaking down serotonin and norepinephrine. • Effective in 50% of patients • Side effects 1 st generation tricyclics (e. g. Elavil, Endep) – partially block the re-uptake of serotonin and norepinephrine. • Side effects
Major Depressive Disorder: Antidepressants 2 nd generation tricyclics (e. g. Prozac, Zoloft, Paxil) – more specifically block the re-uptake of serotonin. Serotonin-specific reuptake inhibitors (SSRIs). • Effective in 60 -80% of patients • Fewer side effects Some caveats: • Antidepressants usually take a month to start working • Don’t work for up to 40% of people
Schizophrenia Severe psychotic disorder of thought; thought and behavior are divorced. Diagnostic criteria: • Bizarre delusions • Paranoia • Hallucinations • Disorders of logical thought and speech • Catatonia or bizarre movements • Inappropriate emotional response/expression
Types of Schizophrenia Positive symptoms üHallucinations (false perceptions) üDelusions (false beliefs) üThought disorders (disorganized thinking and speech) Negative symptoms üFlat affect (emotionless) üImpaired attention üPoor social adjustment üReduction in speech this type has the worse prognosis
Schizophrenia: Dopamine hypothesis Schizophrenia is the result of a hyper-active dopamine system in the brain (excess of dopamine receptors). Antipsychotic drugs: reduce dopamine activity in the brain by blocking dopamine receptors. First generation: thorazine • Side effects – depression, bizarre muscle behavior (shuffle) New generation: “atypicals” (Zyprexa, Risperdal)
Schizophrenia is: A. Caused by extreme stress combined with poor coping skills B. Outcome of extremely exacerbated depressive and anxiety symptoms C. Caused by genetic predisposition combined with environmental stressors D. Primarily a genetic disorder

Schizophrenia: Genetic Component The incidence rate of schizophrenia in… • The general population: 1% • Siblings of schizophrenics: 10% • Fraternal twins of schizophrenics: 10 -15% • Identical twins of schizophrenics: 40 -50%
Schizophrenia: Genetic Component Polygenic model: schizophrenia is caused by a “toxic” combination of genetic variants. Multiple rare variants model: schizophrenia is caused by a single rare mutation
Anxiety Disorders Characterized by distressing, persistent anxiety or maladaptive behaviors to reduce anxiety. Excessive apprehension and anxiety (thoughts of future threat) or fear (present state of heightened physiological arousal).
Generalized Anxiety Disorder Characterized by chronic, excessive worry. Symptoms: • continuous worrying, fearfulness • autonomic nervous system arousal – tension, heart palpitations, trembling, perspiration • difficulties in concentration • avoidance of social situations The anxiety is “free-floating” rather than linked to a specific thing or event.

Social Influence Solomon Asch’s line study Normative social influence: influence resulting from the one’s desire to gain approval/avoid disapproval Informational social influence: influence resulting from one’s willingness to accept others’ opinions
Social psychology & World War II Tendency for humans to be influenced by their social roles (Zimbardo’s Stanford Prison Experiment) Tendency for humans to obey authority figures (Milgram study)
Stanford Prison Experiment Zimbardo set up a fake prison in a basement. College students were randomly assigned to be “prisoners” or “guards”. Study was intended to last for two weeks, but discontinued after 6 days.
The power of social roles Some guards became abusive. Some prisoners became obedient. Some were rebellious, before breaking down emotionally. Zimbardo himself conformed to his role as “warden. ” Our behavior is strongly influenced by the social roles that we find ourselves in.
Milgram’s “shock” experiments Participants were assigned to be a “teacher” to help a “learner” help learn word pairs. Each time the “learner” made a mistake, the “teacher” had to deliver an electrical shock, increasing the level of shock each time. The whole time, a researcher in a labcoat is in the room, giving the “teacher” orders to continue.
What percentage of participants went all the way and delivered the highest level of shock? A. B. C. D. 50% 33% 65% 80%

The power of social influence “Ordinary people, simply doing their jobs, and without any particular hostility on their part, can become agents in a terrible destructive process. ” – Milgram Other influencing factors: • Whether the authority figure was perceived as legitimate and supported by an institution • Whether “learners” were emotionally distanced • Whether “teachers” saw someone else rebel first
