Memory Flashcards
(49 cards)
Stage theory divides memory into…
long-term (LT) and short-term (ST).
Short term memory is referred to as…
“working memory.”
The duration of LT memory is…
relatively permanent.
The duration of ST memory is…
seconds to minutes.
The storage capacity of LT memory is…
infinite?
The storage capacity of ST memory is…
7+/-2 “chunks” (organized packets of information).
Flow of information in memory?
Stimulus-STM-Rehearsal-LTM
The two kinds of rehearsal are…
maintenance and elaborative.
maintenance rehearsal
holds information in STM
elaborative rehearsal
moves information to LTM
primacy effect
in free recall, the tendency to recall the first items on the list more readily than those in the middle
Due to the primacy effect, information is recalled from…
LTM.
recency effect
in free recall, the tendency to recall items at the end of the list more readily than those in the middle
Due to the recency effect, information is recalled from…
STM.
To reduce the primacy effect, you could…
present words faster.
To reduce recency effect, you could…
delay 20th word and recall.
The psychological code of STM is…
phonological (based on speech sounds).
The psychological code of LTM is…
semantic (based on meaning).
The neural code of STM is…
dynamic.
dynamic
pattern of activity among a group of cells
The neural code of LTM is…
structural.
structural
pattern of connections within a group of cells
Trace consolidation occurs during…
elaborative rehearsal.
trace consolidation
memory trace changes from a dynamic to structural pattern
