Term
mnemonists
Definition
memory experts
Term
encoding
Definition
depends on how "deeply" processed, how organized, how manipulated, and how meaningful the information is
Term
memory decay hypothesis
Definition
use it or loose it; natural loss of knowledge
Term
interference
Definition
knowledge interfering with other knowledge (proactive/retroactive)
Term
retroactive
Definition
new information getting in the way of old information
Term
proactive
Definition
old information getting in the way of new information
Term
fan effect
Definition
the more pieces of information you put on the same retrieval cue, the more difficult it is to retrieve any of them
Term
retrieval problem
Definition
is more likely than people ACTUALLY forgetting information
Term
permanent forgetting
Definition
may occur, but is more rare than retrieval problems
Term
intentional forgetting
Definition
an experiment in which people were asked to memorize something then forget that information; later when asked to recall the information they "forgot" they could not however they could remember it and pick it out from a group of information
Term
savings in relearning
Definition
once you've learned something, even if you've forgotten it, relearning it a second time will be faster and easier
Term
levels of processing theory
Definition
the more in depth we learn something the better we remember it; those that aren't are susceptible to rapid decay
Term
state-dependent effects
Definition
retrieval is effected by the bodies state (i.e. drugs, sickness, etc.)
Term
mood-dependent effects
Definition
retrieval is effected by our moods
Term
spacing effect
Definition
more effective to learn something over a long period of time for short intervals than to learn something over a short period of time for longer intervals
Term
context effects
Definition
more effective to remember something in context (i.e. taking a test in the classroom you have lecture)
Term
encoding specificity principle
Definition
things will be better memorized if they are learned with a specific other thing
Term
Rajan Mahadevan
Definition
was able to remember so many digits of pi because he heard digits like music which helped him remember
Term
Akira Haraguchi
Definition
was able to remember so many digits of pi because he said it was relaxing and was like a story to him
Term
Craik & Tulving's recall study
Definition
meaning > lowercase vs. UPPERCASE when remembering
Term
flashbulb memories
Definition
specific memories from a specific time; they are easily biased or stereotyped responses and often misplaced in time
Term
confidence does not equal
Definition
accuracy (.7 correlation)
Term
7 sins of memory
Definition
The -> TRANSIENCE (time)
Baby -> BLOCKING (brigade)
Alien -> ABSENT-MINDEDNESS (aloof)
Made -> MISATTRIBUTION (mistake)
Saturn -> SUGGESTIBILITY (sexual)
Be a -> BIAS (black bias)
Planet -> PERSISTENCE (pest)
Term
encoding variability
Definition
things will be better memorized if they are learned with multiple other loosely related items; more cues, faster retrieval
Term
Goldstein's radical view
Definition
not allow eye-witnesses at all
Term
Buckhout's purse experiment
Definition
people identify innocent bystanders as thief
Term
Brigham's store clerk studies
Definition
took enough time for people to forget who the thief was
Term
identification worsens with (4):
Definition
shorter study time, more faces to study, longer delay before making ID, face in lineup are all similar
Term
Loftu's memory-altering experiment
Definition
using different words (i.e. bumped, smashed, brushed etc.) changed people's perceptions of the crash
Term
misinformation effect
Definition
misleading information can work its way into the encoding of an events and its recall
Term
Bartlett's "War of the Ghosts" study
Definition
game of telephone: details are lost, story becomes more concise, and is affected by cultural experience
Term
7 sins: TRANSIENCE
Definition
as time goes by without rehearsal, your memories are harder to retrieve
Term
7 sins: ABSENTMINDEDNESS
Definition
anything you're not paying attention to is unlikely to be stored in your LTM
Term
7 sins: MISATTRIBUTION
Definition
our source memory is really bad...can't remember where we've learned things from; attribute ideas to ourselves as our own
Term
7 sins: SUGGESTIBILITY
Definition
leading questions and verbal/visual suggestions can lead people to develop false memories
Term
7 sins: BLOCKING
Definition
hard to retrieve information from LTM due to interference
Term
7 sins: BIAS
Definition
our own expectations and desires shape our memories
Term
7 sins: PERSISTENCE
Definition
we forget things we want to forget
Term
procedural memory
Definition
how to do things (apply a rule)
Term
declarative memory
Definition
can be verbalized/described (describe a rule); includes semantic and episodic memories
Term
episodic memory
Definition
memory for specific events, not always accurate
Term
semantic memory
Definition
ABSTRACT, organized by meaning, allows inferences
Term
lexicon
Definition
network of words
Term
priming
Definition
once you activate one word, words that are close by are activated and remain activity for later tasks
Term
repetition priming
Definition
something recently retrieved stays in the mind for future tasks
Term
semantic priming
Definition
words close by are activated via meaning
Term
semantic associative network
Definition
activate one concept and nearby concepts are also activated
Term
retrograde amnesia
Definition
loss of memories before brain damage; almost all amnesiacs show some retrograde
Term
anterograde amnesia
Definition
inability to form new memories after brain damage
Term
Korsakoff's syndrome
Definition
lack of vitamin B1, often associated with heavy drinkers because of their poor diet, damage to the hippocampus, often suffer from retrograde amnesia
Term
bilateral temporal lobectomy
Definition
removal of both sides of the temporal lobe, epileptic patients used to undergo this surgery...now they only do one side
Term
implicit memory
Definition
non-conscious, indirect, implicit learning, & memory tasks
Term
explicit memory
Definition
conscious recollection
Term
process dissociation framework
Definition
controlled vs. automatic rather than explicit vs. implicit
Term
dissociative identity disorder
Definition
episodic memories become illicit and repressed; Freud; painful memories pushed into the unconscious
Term
source monitoring error
Definition
when a specific experience in incorrectly determined to be the source of a memory
Term
ACT model of memory
Definition
How do we know what knowledge is relevant?

(1) Procedural and (2) declarative memory are organized in networks, and activated information is (3) working memory
Term
Venn Diagram
Definition
Procedural on its own and episodic and semantic interrelated
Term
The case of HM
Definition
Procedural memory: INTACT
Episodic memory: IMPAIRED
Semantic memory: SOMEWHAT IMPAIRED
*was able to learn, though slowly

EVIDENCE OF A DOUBLE DISSOCIATION
Term
dual-coding hypothesis
Definition
visual imagery is rich with information and people are better at recalling images than information
Term
relational-organizational hypothesis
Definition
visual imagery creates more associations: picturing the penguin eating the doughnut will be a better mnemonic then just a penguin with a doughnut
Term
mental imagery
Definition
perceptual experience in the absents of stimuli
Term
visual imagery
Definition
relationship between perception and encoding/storage and later retrieval
Term
method of loci
Definition
(local grocery store): story of grocery store items in specific places in house
Term
pegword system
Definition
(peggy and marissa like apples): visualizing objects as memory cues instead of locations
Term
interactive images
Definition
(two friends named carol doing something together): visualizing them doing something together will strengthen the association and help you remember their names
Term
mnemonics work by (2):
Definition
dual-coding or relational-organizational
Term
Sherpard & Metzler 3-D studies
Definition
people are just as fast to rotate 2-D objects as they are with 3-D objects; the farther the objects are away from one another the more difficult it is to decide if they are the same
Term
Carmichael's glasses-dumbbell study
Definition
suggestion led people to believe that a simple drawing was either a pair of glasses or a dumbbell
Term
Chamber's & Reisberg's study about reinterpreting ambiguous figures
Definition
were able to see a duck or rabbit but not both in five seconds; could not image another image but if they redrew the image in their minds they could then see both on the paper
