Memory Flashcards
According to stage theory, human memory is divided between…
long term and short term memory.
Short term memory is referred to as…
“working” memory.
The duration of long term memory is…
relatively permanent.
The duration of short term memory is…
second to minutes.
The storage capacity of long term memory is…
infinite?
The storage capacity of short term 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
If asked to read 20 words one at a time and recall them in any order, the primacy effect would mean that…
the early part of list recalled better than middle (recalled from LTM).
If asked to read 20 words at a time and recall them in any order, the recency effect would mean that…
the last part of list recalled better than middle (recalled from STM).
Reduced recency means…
delay between 20th word and recall.
Reduce primacy means…
present words faster.
According to psychological code, STM is…
phonological; based on speech sounds (Confuse “boat” with “coat”).
According to psychological code, LTM is…
semantic; based on meaning (Confuse “boat” with “ship”)
According to neural code, STM is…
dynamic
dynamic
pattern of activity among a group of cells
According to neural code, LTM is…
structural.
structural
pattern of connections within a group of cells
trace consolidation
occurs during elaborative rehearsal; memory trace changes from a dynamic to structural pattern
Amnesia interrupts…
the consolidation process.
Retrograde amnesia cannot recall memory…
before trauma.
Anterograde amnesia cannot recall memory…
after trauma.
