Chapter 6- Memory Flashcards
Myths about memory:

- memory is not A thing (correlated to all senses)
- memory can be affected (other sources, self fufilling prophecy)
Does intelligence determine memory?
No
Encoding
making sense out of an experience to remember it to store it, transforming experience
ex:) coding a computer
Storage
maintaing information
ex:) saving/storing the file

all memory starts with an input, that input goes into sensory memory (it has a HUGE capacity, small/short duration)
George Sperling

Sperling-> visual scene
Iconic memory
visual memory, (fast decaying -> 1 second)
ex:) iconic->photo->visual memory
Echoic memory
auditory memory (fast decaying-> 5 seconds)
ex:) echo->sound->auditory memory
primacy effect
you remember things at the very beginning (like on a grocery list)
recency effect
remembering things at the very end (like on a grocery list)
serial position curve
people remember the beginning and the end, forget the middle
short term memory
memory that decays after 15-30 seconds
rehearsal
repetition that makes information stick in your head
decay
when learned material dies/leaves the brain
interference
distraction during memorization that makes it difficult to recall information
George Miller
people could remember 7 (+/- 2) separate individual digits (recent research says it is lower now, 4 +/- 1)
“Killer numbers”
chunking
putting small groups of letters/numbers together to remember them
