Chapter 3: Experimental: Memory (7-9%) Flashcards
Stages of Memory
Sensory
Short-Term
Long-Term
Studying Memory
Involves understanding how things are remembered and why things are forgotten.
Sensory Memory
- Last only for seconds
- Forms the connection b/t perception and memory
Iconic Memory
is the sensory memory for vision
George Sperling
Found that people could see more than they can remember
Ulric Neisser: Icon
For brief visual memory and found that an icon last for about one second.
Backward Masking
When subjects are exposed to a bright flash of light or a new pattern b/f the iconic image fades, the image will be erased. (More successful if it similar to the original stimulus)(works for auditory system as well)
Echoic Memory
is the sensory memory for auditory sensations
Short-Term Memory (STM)
Teporary; lasts for seconds or minutes
Working Memory
is the temporary memory that is needed to perform the task that someone is working on at that moment
George Miller
Found that short-term memory has the capacity of about seven items (+ or - two items)
Chunking (grouping items)
can increase the capacity of STM
Rehearsal
(Repeating or practicing) is the key to keeping items in the STM and to transferring items to the long-term memory (LTM)
Primary (maintence) Rehearsal:
Involves repeating material in order to hold it in STM
Secondary (elaborative) Rehearsal
Involves organizing and understanding material in order to transfer it to LTM
Interference
How other information or distractions cause one to forget new items that were presented
Proactive Interference
Disrupting information that was learned before the new items were presented
-This is problematic for recall and thus causes proactive inhibition
Retroactive Interference
Disrupting information that was learned after the new items were presented.
-This is problematic for recall and thus causes retroactive inhibition
Long-Term Memory (LTM)
- Capable of permanent retention
- Most items are learned semantically, for meaning
- LTM retention is measured by recognition, recall and savings
Recognition
Recognize things learned in the past
Ex. M. choice test
Recall
Generate information
Cused Recall
remembering w/ cues
Free Recall
Remembering w/o cues
Savings
Measures how much information about a subject remains in LTM by assessing how long it takes to learn something the second time as opposed to the first time.
