  18. Diagnostic and Statistical Manual of Mental
    Disorders (DSM)
    begining of modeern illness classification
    outlined behavioral therapy, focusing research on observable behavior rather than infered states of mind.
  20. three main levels of analysis
    • bio influences-genes
    • physc influences-emotional
    • socail culture influenes
  21. How do physcologists do what they do?
    Case studies, surveys, naturalistic observation and other methods
    • GOOD: similar to case study but uses many more individuals ; less likely to catch a whole group of wierdo's
    • BAD: self reporting is notoriously bad. People have biases that prevent honest reporting. (not reliable)
    • GOOD: individual cases studied in depth much info is derived from the individual case
    • BAD: subjects of the case studies may not be "normal"
  24. Naturalistic observation
    • good: provides a view of behavior in its natural context less performance pressure for those studied
    • bad: enviormental conditions that may influence behavior
  25. neurons
    nerve cells
    cell body
    the cells life support center
    recieves messages from other cells
  28. axon
    passes messages away from the cell body to other neurons
  29. terminal branches of axon
    form junctions with other cells
  30. action potential
    a brief electical charge or voltage that travels down its axon; triggered by impulses
  31. threshold
    minimum intensity
  32. synapse
    the meeting point between neurons; junction
  33. nuerotransmitters
    release of chemical messangers
  34. reuptake
    the sending neurons reabsorbs excesss neurotransmitters
  35. serotinin pathways
    • serotonin-chemical
    • affects mood hunger sleep and arosal
  36. dopamine pathways
    • involved with diseases
    • influences movement, learning attention and emotion
  37. agonists
    looks like it, and acts like it
  38. antagonist
    looks like it, doesnt act like it
  39. central nervous system

  45. sympathetic nervous system
    aroses the body; fight or flight
  46. parasympathetic nervous system
    calms the body; rest and digest
  47. the endocrine system
    the bodys slow chemical communication system
  48. hormones
    travel through the bloodstream and affect other tissue; affect sex hunger and mood
  49. adrenal glands
    increase heart rate, blood pressure and blood sugar; provides us with a surge of energy
  50. pituatiry gland
    pea sized located in the core of the brain; influence the release of hormones and influence growth
  51. lession
