Memory Flashcards
1
Q
what is memory?
A
- a consequence of information processing
- memory is the reason that previously processed information can affect current information processing
2
Q
what is direct influence of memory?
A
deliberate attempt to search/retrieve past experience
3
Q
what is indirect influence of memory
A
- not a conscious recollection of memory
- motor skills
4
Q
what are the three stages of memory storage?
A
1) short term sensory store (STSS)
2) short term memory (STM) (working memory)
3) long term memory (LTM)
5
Q
what is the short term sensory store (STSS)?
A
- “sensory register”: pattern matching
- holds massive amounts of info briefly then info fades
- stores literal info < 1 sec
- limitless capacity
6
Q
what are characteristics of short term memory (STM)?
A
- storage system for info from STSS or LTM, termed “working memory”
– effortful, conscious processing, and integration - loses info rapidly (30-60s) unless rehearsed
- limited capacity of +/-7 items
- abstract coding
7
Q
how does STM integrate with STSS and LTM?
A
- info from STSS stored for processing
- info from LTM retrieved for processing and joined w STSS info to create “action plan”
- closely related to response-selection stage of IP
8
Q
what are the characteristics of long term memory (LTM)?
A
- practiced items are “protected” and more permanently placed in LTM
- limitless capacity and duration of LTM
9
Q
what is implicit (non-declarative or procedural) memory?
A
- part of LTM
- being able to do something w/o conscious thought
- skills, tasks, habits
10
Q
what is explicit (declarative) memory?
A
- part of LTM
- episodic (events)
- semantic (recall facts, meaning)
- can also influence conscious motor task learning and performance
11
Q
how is LTM used effectively?
A
- transfer info accurately into LTM
– encoding/consolidating - accurately retrieve information
– recall info from different long term storage sites
– most accurate when retrieved in the same context in which it was created
