memory Flashcards
memory
an information processing system that works constructively to encode, store, and retrieve information
3 key memory processes
- encoding
- storing
- retrieving
how does forgetting occur?
failure of any 3 of the memory stages to take place
encoding
process that controls movement from STM (working memory) to LTM (getting information in)
storage
to keep memory in the STM through rehearsal or practice
retrieval
process that controls flow of information from LTM to STM (getting information out)
3 major stages of memory
- sensory memory
- short-term memory (STM)
- long-term memory (LTM)
what 3 factors do the stages of memory differ in?
- capacity - how MUCH info can be stored
- duration - how LONG the info can be stored
- function - what is DONE with the info stored (capacity+function)
sensory input
everything we see, hear, taste, touch, and smell
when sensory input is ENCODED, it goes into our
sensory memory
sensory memory
function - holds information long enough for it to be processed for basic physical characteristics
capacity - large (can hold many items at once)
duration - very brief retention
_____ is needed to transfer info from sensory memory into working memory
attention
sensory memory is divided into 2 types
- iconic memory (visual info) - retained for around 250s
- echoic memory (auditory info) - retained for around 3s
psychologists believe that during the sensory memory stage, there is a separate register for each sense
iconic memory - eye
echoic memory - ear
tactile memory - touch
olfactory memory - smell
gustatory memory - taste
which memory stage forms automatically without attention or interpretation
