STM

Question 1

what is memory

Answer 1

process involved in retaining, retrieving and using information about stimuli, images, events, ideas, and skills after the original information is no longer present

Question 2

what is sensory memory

Answer 2

brief stage of memory that holds info for seconds or fractions of a second. 1st stage of the modal model of memory

Question 3

what is STM

Answer 3

a memory mechanism that can hold a limited amount of info for a brief period of time (30sec), unless there is rehearsal to maintain the info in STM

Question 4

what is LTM

Answer 4

a memory mechanism that can hold large amount of info for long periods of time

Question 5

what is the modal model of memory

Answer 5

memory as a mechanism that involves processing information through a series of stages, including STM and LTM
info form sensory memory–> STM
STM contains just the right amount of info that is actively processed (fragile and can be erased in -30 sec except repitition)
repitition leads to –> LTM
LTM has large information storage capacity
info in LTM is semantically encoded and relatively permanent

Question 6

material stored in STM less than ____ is frequently forgotten

Answer 6

1min

Question 7

to keep info in STM, you need to _____ it

Answer 7

repeat

Question 8

how many digits can a person remember

Answer 8

5-9

Question 9

what is chunking

Answer 9

combining small units into larger meaningful units
collection of elements strongly associated with one another but weakly associated with elements in other chunks

Question 10

what is working memory

Answer 10

limited-capacity system for temporary storage and manipulation of information for complex tasks
comprehension, learning, reasoning
storage, process and manipulates information

Question 11

Baddeley’s WM model

Answer 11

phonological loop: verbal and auditory information
- phonological store: limited qt of verbal and auditory info for secs
- articulatory rehearsal process: rehearsal process in WM that keeps items in phonological store (we translate everything into phonological form to rehearse)
- phonological similarity effect: acoustic confusion
central executive: coordinates both. determining role in overall functions or WM, diff to study
visuospatial pad: visual and spatial information (verbal info encoded as visual images)
- limited capacity, if too many items = no precise representation = cant be retrieved correctly

Question 12

Revised WM model

Answer 12

central executive
Phonological loop
Episodic buffer: backup store taht communicates w/ LTM and WM
holds info longer and more info than PL and VSP
visuospatial sketch pad
