Show Answers:

  1. explicit memory
    memory for specific information. the information may be autobiographical or refer to general knowledge
  2. implicit memory
    memory of how to perform tasks. memory that is suggested but no plainly expressed--people do know but don't state clearly.
  3. priming
    repeating information until information activation of a memory is easly enough to make without making a huge effort.
  4. serial-position effect
    the tendency to recall the first and last items in a series
  5. chunking
    grouping stimuli in a group that is percieved as a discrete piece of information. the average person is comfortable with chunking 7 numbers a clip
  6. tip of the tongue phenomenon
    • the feeling that information can be stored in memory althought it cannot be readily retrieved.
    • reflects incomplete or imperfect learning
    • often retrieve information that is closed to the actual information being sought--sound the same or look the same.
  7. state-dependent memory
    • an extension of context-dependent memory
    • information that is retrieved in the physiological or emotional state in which it was encoded and stored or learned.
    • we retrieve information when we are moods that are similar to the moods we were experiencing when we learned the information.
  8. recognition
    • easiest memory task
    • realizing that you have experienced a piece of information before
  9. recall
    retrieval or reconstruction of learned material
  10. relearning
    • a measure of information retention
    • material usually relearned more quickly than it is learned
    • learningspanish when your in high school may make relearning spanish when you are much older
  11. retroactive interference
    • interference of new learning with the ability to retrieve material learned previously
    • memorizing the leg bones make make it harder to recall the arm bones. (new info is blocking the old info being recalled)
  12. proactive interference
    • interference by old learning with the ability to retrieve information learned recently
    • (old info is blocking new information from being learned)
  13. long-term potentiation
    • enhanced efficiency in synaptic transmission that follows brief, rapid stimulation
    • when you are conditioned to a stimuli, you release more serotonin
    • in effect, transmission at these synapses becomes more efficient as trials (learning) progress
    • kinda like your weeding a path over and over again until the path becomes trodden down
  14. hippocampus and memory
    does not become mature until we are 2 yrs old. we cant remember things before then because our hippocampuses are not fully developed.
  15. herman ebbinghaus
    • studied memory
    • tested himself to see how long he could remember lists.
    • formulated a forgetting curve
    • demonstrated that one could study memory scientifically
  16. visual encoding
    when we mentally represent information as a picture
  17. semantic encoding
    representing stimuli in terms of their meaning
  18. acoustic encoding
    mentally representing information as a sequence of sounds
  19. mneumonics
    form of visual encoding
  20. mood dependency
    • the mood youre in affects the type of memories you are best able to recall
    • i.e bad mood=bad memories
