Week 4- Memory and Information Processing Flashcards
Steps of Information Processing Model
- sensory input to sensory memory (attention to the info)
- Working memory (maintenance rehersal
- info gets encoded into long term memory
-some unpractice info lost overtime
Capacity of sesnory memory
large
capacity of working memory
small 7 +/- 2
Capacity Long term memory
large
Duration if sensory memory
very short
visual less than 1 second
auditory = 2 -3 seconds
Duration of working memory
5-20 seconds
Duration of long term memory
indefinitely long
What factors impact sensory memory stage
-sensory input
-automatic encoding
-effort encoding
Factors that impact memory processing in the working memory stage
-attention and environment
-information overload
-inhibitory control
-selective attention, stroop task
-Rehearsal
–organization
–elaboration high level processing
Factors impacting memory processing in long term memory stage
retrievel
-recall and recognition
-forgetting and decay
-interference: the presence of competing or similar information hampers the ability to retrieve a specific memory
Age trends in information processing
-processing speed increases and peaks in adolescence
Age trends in infants
have some long term memory
-average age of first memory is 3-4 years (childhood amensia)
Age trends in early childhood
preschoolers often display good long term memory, may need adult help
-memories are fragile (memory errors/false memory)
Age trends in middle childhood
have more items in long term memory
improve in:
-remembering source of info
-metamemory
-remembering to do something in the future
-using effective memory strategies
Age trends in adolescence
memory quality improves
memory strategies improve
-more likely to use elaboration
