  4. what are the two theories of sleep?
    circadian theory and restorative theory
  5. what does the circadian theory state?
    sleep evolved to keep humans out of harm during the night time

  8. what effects do stimulants cause?
    stimulants speed up the activity in the central nervous system, suppress appetite, cause a person to feel awake, alert and energetic. (caffeine, nicotine, amphetamines, cocaine) (can increase heart rate and blood pressure)
  9. effects of depressants?
    slow down activity in the central nervous system. Slow down bodily functions, reduce sensitivity to stimulants. (alcohol, tranquilizers, narcotics) (can lead to loss of consciousness
  10. effects of hallucinogens?
    alter and distort perception of time and space as well as mood. cause hallucinations and feelings of unreality. (marijuana and ecstasy)
  11. what is memory?
    memory is the process of encoding storing and retrieving information
  12. what is encoding?
    encoding is the process of transforming information into a form that can be stored into mind

  14. what is retrieval?
    process of bringing information to the mind
  15. what are of the brain is responsible for memory?
    located in the pre-frontal cortex of the brain
  16. what is the Atkinson & Shiffrin three memory system?
    memory model that divides memory into three different systems.

    • sensory memory
    • short term memory
    • long term memory
  18. What is sensory memory for?
    stores information from the senses (visual images or sounds)
  19. what is short term memory for?
    stores information currently being used
  20. what is long term memory?
    stores information from minutes to a life time
  21. what is the capacity of sensory memory?
    between 5-9 items. from a fraction of a second to two seconds
  22. short term memory capacity?
    short term memory stores between 5-9 items. 30 seconds without rehersal
  23. what is the capacity of long term memory?
    virtually unlimited. from minutes to a lifetime
  24. rehearsal?
    purposely repeating information currently being used to keep it in short term memory
  25. displacement?
    when short term memory is full and a new item is learned an older item is pushed out and forgotten
  26. automaticy?
    ability to recall information from long term memory without any effort (developed overtime, like reading)
  27. what are the two types of long term memory?
    declarative and non-declarative memory
  28. what is declarative memory?
    stores fact, information and personal experiences that can be brought to mind verbally or images
  29. what is episodic memory?
    records events as they been experienced (trip to Hawaii)
  30. what is semantic memory?
    stores general knowledge or objective facts and information
  31. non-declarative memory?
    stores motor skills, habits and conditioned responses
  32. motor skills
    acquired through practice and the memory for motor movements (riding a bike without thinking about it)
  33. classically conditioned responses
    things learned through conditioned responses (feeling sick at the smell or sight of certain food)
  34. serial position effect?
    with items learned in a sequence, there is a better recall for the beginning and ending items than those in the middle o
  35. reconstruction?
    an account or event pieced together from a few highlights (what did you do last weekend?)
  36. context effect?
    better recall of information in the context it was learned
  37. possible cause of forgetting?
    decay, encoding failure, interference, consolidation failure, motivated forgetting, prospective forgetting, retrieval failure.
  38. what is recall?
    must provide information by searching memory. (fill in the blank) (stimulus of a bit of information that aids retrieval)
  39. what is recognition?
    identify familiar material as it has been encountered before (multiple choice, matching, true & false)
  40. what is relearning?
