- 1800's: consised as a sickness that could not be diagnosed and treated
Historically, what are the three different approaches that have been taken to addressing the problem of mental disorders? In particular, what is meant by the medical model and the bio-psycho-social perspective? (How are they different?)
- acknowledgment that all behavior arises from the interaction of nature and nurture- a disorder may be due to either one of the other or BOTH!
What is the DSM-IV? What kind of information does it contain about mental disorders?
- defines 16 major categories of "mental disorder"
describes them in terms of: 1. symptoms. 2. prognosis3. appropriate treatment
What social and ethical problems are associated with labeling an individual as having a particular psychological disorder?
- diagnosis is important for getting appropriate treatment and health insurance
- HOWEVER, once identified as having a mental disorder, a patient may be subject to bias an stereotyping
What are the five major types of anxiety disorders discussed in lecture? What are their symptoms and how prevalent are they? (You don’t need to know the exact prevalence, but you should have a rough idea how common they are.)
1. Panic Disorder- intense terror episodes w/ physical symptoms (agoraphobia) 2. Generalized Anxiety Disorder (GAD)- persistent state of apprehension and ANS arousal3. Phobias- irrational fear of a subject, object, activity, or situation. 4. Obsessive- Compulsive Disorder- inability to control repetitive thoughts or actions5. Post Traumatic Stress Disorder (PTSD)- persistent, heightened state of anxiety that develops after exposure to a terrifying event or ordeal
prevalence: 2-10%more common in womenbecoming more common...
What are some of the proposed causes of anxiety disorders?

The Learning Perspective: anxiety is learned an maintained primarily through classical conditioning, stimulus, generalization and reinforcementThe Biological Perspective: anxiety disorders correlate with overactive frontal lobes and amygdala, partly heritable, and many phobias may be adaptive
What are the similarities and differences between the learning perspective and the biological perspective?
Both deal with how anxiety disorders arise
learning says its the outside worlds that influences us.
biological says the anxiety is already within us
Overactivity in what part of the brain is associated with anxiety disorders?
Frontal lobes and amygdala
What is major depression? What are its important defining characteristics? (i.e., that distinguish it from more common forms of temporary depression). Are men or women more likely to experience major depression? Who is more likely to commit suicide?
- prolonged feeling of worthlessness and diminished interest and pleasure in most activities w/ no apparent cause- UNIPOLAR- factors about 80% of suicides- men are more likely to commit suicide (more successful at it)
What is bipolar disorder? How does it differ from major depression? In terms of symptoms? Prevalence? Gender differences? Genetics?
- Manic Depression- alternating periods of depression and mania (hyperactive, impulsive, wild behavior) - no gender difference- strong genetic component
What evidence exists for the role of genes and biology for mood disorders? What is the social-cognitive perspective?
- Biologically, there is a strong genetic predisposition, especially for bipolar disorder- correlates with reduced activity of serotonin and norepinephrine + reduced frontal lobe activity
- belief that depression is a vicious cycle fed by self-defeating beliefs- negative interpretations of events encourage negative moods.
What is schizophrenia and what are its most prominent characteristics? How prevalent is it, and what age group is most susceptible?
- psychotic disorder characterized by delusions, disordered thinking, and bizarre behavior- 1-2% - no gender of racial differences- onset occurs at young adulthood
What types of brain abnormalities are observed in schizophrenics and what neurotransmitter is thought to be involved? What do studies about the heritability of schizophrenia tell us about its causes?
Answer 13
+ - excess of behavior- - poverty of behavior
- overactivity of dopamine (in the nucleus abumbens) - enlarged ventricles/decreased temporal lobe volume
- it's GENTIC: high concordance rate for identical twins
What evidence exists for environmental causes of schizophrenia? In particular, why do some researchers believe that prenatal factors may play an important role?
- viral infections, prenatal complications and flu epidemics assiciated with higher rates. - does not correlate with parenting skills
What are the defining characteristics of personality disorders?
Characterized by maladaptive behavior patterns (excluding anxiety and depression) that impair social functioning
