  1. abnormal psychology
    • the scientific study of psychological disorders
    • thought to occur in at least 22% of adults in canada every year
  2. general paresis
    • mental condition caused by syphilis
    • caused delusions, halluncinations, inappropriate moods, full blown dementia, seizures and death
    • males 20-40
    • showed that madness could be symptoms of an underlying physical illness
  3. moral treatment
    • mental health reform following the discovery of syphilis
    • which led to more humane treatment of the mentally ill
  4. medical model
    • approach to understanding and treating mental illness
    • encourages a search for patterns in the symptoms people present with
    • search of possible causes
  5. defining psychological abnormality: the 4 d's
    • deviance - behaviours, thoughts, emotions that differ from a society ideas
    • distress - actions must also cause distress
    • dysfunction - hurt daily functioning
    • danger - to themselves or others (seems to be the exception rather than the rule, most would never hurt others and pose no immediate danger to themselves or anyone else)

    All rely heavily on social norms and values
  6. classification system
    list of disorders with descriptions of the symptoms and guidelines for determining when individuals should be assigned to the categories
  7. international classification of diseases
    the system used by most countries to classify psychological disorders; published by the world health organization and currently in its tenth edition
  8. Diagnostic and statistical manual of mental disorders (DSM)

  9. diagnosis
    a clinicians determination that a person's cluster of symptoms represents a particular disorder
  10. comorbidity
    the condition in which a person's symptoms qualify him for two or more diagnoses
  11. model or paradigm
    a big idea about how things work
  12. neuroscience model
    • view abnormal behavior as an illness brought about by a malfunctioning brain
    • ex. Huntington - loss of brain region called striatum
    • ex. depress - insuffictient noepi and serotonin (maybe cortisol as well)
    • genetics (alzhiemers) and viral infections (schizophrenia, mood and anxiety disorders) could play a role
  13. congnitive - behavioural model
    prosoe that psychological disorders result largely from a combination of problematic learned behaviours and dysfunctional cognitive processes.
  14. the behavioural perspective
    • learning principles to explain human functioning
    • abnormal behaviours acquired through learning (classical, operant and modelling)
    • can be tested
    • helpful to people with - specific fears, compulsive behavriours, social deficits, intellectual disabilities and a wide range of other problems
  15. the cognitive perspective
    • when people display abnormal patters of functioning, cognitive problems are to blame
    • maladative beliefs and illogical thinking processes
    • eg. thinking your a failure
    • eg. illogical thinking patters than are common in the depressed - selective percetion: only seeing the negative, magnification: exaggerating the importance of undesirable events, overgeneralization: drawing broad negative conclusions on the basis of a single insignificant event
    • thought it is a key factor
  16. psychodynamic model
    • frued, childs development may lead to non maturing and fixation

    • Factors: social change, socio-economic class, cultural factors, social networks and supports, family systems
  19. social change: the socio-cultural model
    when a society undergoes major change - urbanization: usually show a rise in mental disorders
  20. socio-economic class: the socio-cultural model
    lower socio-economic class have higher rates of psychological abnormalilty expecially severe abnormality.

    • force individual members of the family to react in ways that otherwise seem abnormal
    • if act normal (aka against family norms) creates turmoil
  24. developmental psycopathology

    • look at genetics, early environmental influences and their own psychological processes
  25. risk factoris
    biological and environmental factors that contribute to problem outcomes
  26. equifinality

  42. attribution-helplessness theory
    • revised newer version of learned helplessness
    • when people view events to be beyond their control, they ask themselves why this is so
    • if they attribute their present lack of control to some internal cause that is both global (wide ranging) and stable (a deficiency that will continue for a long time), they may well feel helpless to prevent future negative outcomes and experience depression

  62. how do cognitive-behavioural theorisits explain obsessive compulsive disorder
    • after repeated accidental associations, they believe that the action is brining them good luck or actually chaing the situations - perform the action more and becomes a key method of avoiding or reducing anxiety
    • people with obsessive compulsive disorder experience intrusive thoughts more often, and gain a reduction in anxiety after using neutralizing techniques (aka compulsions)
  63. How do neuroscientists explain obsessive-compulsive disorder
    • two lines of research
