chapter 8 - memory Flashcards
memory
persistence of learning over time though encoding, storing, & retrieving information
recall
intentionally retrieving info from LTM, brining it into STM
recognition
matching an item to a stored memory
relearning
we learn more than we can recall
in order to remember..
info must go in (encoding)
info must be retained (storage)
info must be retrievable (retrieval)
recall is _____ than learning
harder
we learn _____ than we can recall
more
what does each memory system have?
duration
-how long memories last
capacity
what are the three memory systems?
sensory memory (SM)
short-term memory (STM)
long-term memory (LtM)
sensory memory properties
properties
* the memory has a very short duration (less than a second)
* large capacity (takes in everything)
lingering activation in perceptual areas of the brain
* iconic memory (vision_
* echoich memroy (audition)
* studied using the spirling technique
attention play a ______ roll in moving information from SM to STM
large
short term memory
**properties **
* short duration (few seconds)
* small capacity (7 +/-2 items)
* useful for
* remembering telephone numbers
* language use
how to extend capacity for STM
we use strategies to extend STM
increasing capacity
-chunking (phone numbers)
increase duration
-rehersal
what makes you more likely to recall the first items
primacy effect
what makes you more likely to recall the last items
recency effect
serial position effect
the tendency when learning information in a long list, to more likely recall the first items (primacy effect) and the last items (recency effect)
long-term memory
properties
* (very) long duration (hours to decades)
* very lage capacity (always room for more memories)
*
types of LTM (review this slide)
automatic and effortful
* implicit memories (automatic)
* explicit memories (declarative- with conscious recall)
where is explicit memory processed?
frontal lobe
explicit memories
conscious awareness; easy to verbalize
what do explicit memories include?
sematic and episodic
implicit memories
no conscious awarness; hard to verbalize
what do implicit memories include?
skills or habits (how to ride a bike)
explicit memories: semantic vs episodic
semantic - facts
-word meanings (a sog is an animal)
-concepts (heat rises)
-general facts (my dogs name is kona)
episodic - events
-events that occured to you (buying a dog)
-enclude context (when, where)
