Psychological Perspectives

A
  • Freud believed that psychological disorders are caused by unresolved conflicts

Q

Vulnerability-Stress Model

A

…everyone has some degree of vulnerability to developing a disorder

  • Vulnerability can have biological basis, brain malfunction, or hormonal factor
  • Can also arise from personality factors such as low self-esteem
  • Vulnerability often only causes disorder when a stressor combines with it to trigger the appearance of the disorder

Q

Causal Factors in Anxiety Disorders

A
  • Genetic factors
  • Abnormally low levels of GABA activity may cause people to have highly reactive nervous systems that quickly produce anxiety responses in response to stressors
  • Biological preparedness makes it easier to learn to fear certain stimuli, and may explain why phobias seem to centre on certain classes of primal stimuli and not on more dangerous modern ones, such as guns

  • About 10% will not recover
40
Q

Causal Factors in Mood Disorders
