  1. psychological disorder
    • the presence of a constellation of symptoms that create significant distressimpair work, school, family, relationships, or daily living; or lead to significant risk of harm
    • symptoms: cognitive, emotional, behavrioural
  2. psychosis
    impaired perception and comprehension, plus disorganized behariour
  3. delusions
    false beliefs
  4. abnormal psychology
    • scientific study of psychological disorders
    • no universal definition of what is abnormal behaviour
    • agreed-upon features (4 d's) - deviance, distress, dysfunction, danger
  5. diathesis stress model
    vulnerability for psychological disorders can be triggered by stress
  6. dsm-IV: axis
    • axis 1: clinical disorders (e.g Mood disorders)
    • axis 2: personality disorders (e.g narcissism and mental retardation)
    • axis 3: general medical conditions
    • axis 4: psychosocial and environmental problems
    • axis 5: global assessment of functioning
  7. rosenhan
    falsely admitted himself to a mental hospital then stopped having symptoms to show how bad it is in the hospitals
  8. the neuroscience model
    • view disorders as illnesses caused by a malfunctioning brain
    • factors contributing
    • 1. genetic inheritance (mood disorders, schizophrenia, mental retardation, alzheimers)
    • 2. too few or too many of certain types of neurotransmitters
  9. Neuroscience model: causes
    • viral infection: fetal or childhood exposure and schizophrenia
    • hormones: excess cortisol in depression
    • specific brain structures: huntington's disease and loss of cells in the striatum
    • does not take into account additional factors such as stress, experiences
  10. antisocial disorders and the brain
    no link between abnormal brain structures and antisocial patters
  11. cognitive-behavioural model
    • disorders are the result of maladaptive learned behaviours and problematic thinking
    • -behaviour and thinking interact and influence each other
    • - acknowledge that emotions and biological factors also interact with behaviour and cognition
  12. behavioural perspective
    based on learning principles from classical conditioning, operant conditioning, and modelling
  13. cognitive perspective
    • maladaptive beliefs and illogical thinking processes cause distress
    • beliefs about the self and the world
    • arbitrary inferences: negative conclusions based on little evidence
    • selective perception: seeing negative features of events
    • magnification: exaggerating the importance of negative events
    • overgeneralization: broad, negative conclusions
  14. psychodynamic model
    • underlying, perhaps unconscious psychological forces cause conflict
    • rooted in freudian theory
    • fixation: being trapped at an early stage of development due to traumatic childhood experiences
    • object relations theorisits: believe people's primary  motivation is to form relationships - problems in early relationships result in psychological problems
    • unsupported by research - the whole model
  15. the socio-cultural model
    • a society's characteristics create stressors for some of it's members
    • -widespread social change

  16. family systems
    family systems theory: a theory holding that each family has its own implicit rules, relationship structure, and communication patterns that shape the behaviour of the individual members
  17. The Developmental psychopathology model
    study how problem behaviours evolve as a function of a person's genes and early experiences and how these early issues affect the person at later life stages
  18. The Developmental psychopathology model: risk factors, equifinality, multifinality, resilience
    • risk factors: biological and environmental factors that contribute to problem outcomes
    • equifiniality: the idea that different children can start from different points and wind up at the same outcome
    • multifinilaty: the idea that children can start from the same point and wind up at any number of different outcomes
    • resilience: the ability to recover from or avoid the serious effects of negative circumstances
