Memory Flashcards
Studying memory involves:
understanding how things are remembered and why things are forgotten
Stages of memory
sensory, short-term, long-term
How long does sensory memory last?
Seconds
Role of sensory memory
Forms the connection between perception and memory
Iconic memory
sensory memory for vision; people can see more than they can remember
Icon
Brief visual memory; lasts about one second
Backward Masking
When subjects are exposed to a bright flash of light/new pattern before the iconic image fades, the first image will be erased. Works in auditory system as well
Echoic memory
Sensory memory for auditory sensations
How long does short-term memory last?
Seconds/minutes; temporary
Working memory
Temporary memory needed to perform the task that someone is working on at that moment
Capacity of short-term memory
7 items, +/- 2
Chunking
grouping items; can increase capacity of STM
Sense most associated with STM
Auditory
Rehearsal
Repeating/practicing; key to keeping items in STM and transferring items to LTM
Primary rehearsal
Involves repeating material in order to hold it in STM
Secondary Rehearsal
Involves organizing and understanding material in order to transfer it to LTM
Interference
How other information or distractions cause one to forget items in STM
Proactive interference
Disrupting information that was learned before the new items were presented, eg. a similar list of words. Causes proactive inhibition
Retroactive Interference
Disrupting informatino that was learned after new items were presented; causes retroactive inhibition
LTM is capable of…
permanent retention
Items in LTM are learned…
semantically
LTM retention is measured by…
recognition, recall, and savings.
Recognition requires…
Subjects to recognize things learned in the past. eg. memory required for multiple choice tests.
Recall requires…
Subjects to generate information on their own
