memory
answer
the persistence of learning ocer time thru the storage and retrieval of info
question
flashbulb memory
answer
a clear memory of an emotionally significant moment or event; but can err
question
encoding
answer
the processing of info into the memory system- for example, by extracting meaning
question
storage
answer
the retention of encoded info over time
question
retrieval
answer
the process of getting info out of memory storage
question
sensory memory
answer
the immediate, very brief recording of sensory information in the memory system
question
short-term memory
answer
activated memory that holds a few items briefly, such as the seven digits of a phone number while dialing, before the information is stored or forgotten
question
long-term memory
answer
the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences.
question
three-stage processing
answer
Atkinson and Shiffrin's model of memory; suggests we form memories thru 3 stages: sensory, short-term, long-term memory; limited and fallible
question
working memory
answer
a newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory. Content quickly fades unless we keep using or rehearsing it
question
central executive processor
answer
coordinates the auditory and visual-spatial elements of working memory; directs focus
question
automatic processing
answer
unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings
question
effortful processing
answer
encoding that requires attention and conscious effort
question
rehearsal
answer
the conscious repetition of information, either to maintain it in consciousness or to encode it for storage
question
Ebbinghaus
answer
German philosopher, researched verbal memory; learned that the amount remembered depends on the time spent learning
question
overlearning
answer
additional rehearsal even after we learn material; increases retention
question
next-in-line effect
answer
when ppl go around in circle saying words or their names, poorest memories are for what was said by the person just before them; we focus on our own performance and fail to process last person's words
question
spacing effect
answer
the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice; the longer the intervals in between repeated studying or practicing, the longer you'll remember it
question
serial position effect
answer
our tendency to recall best the last and first items in a list; for immediate recall, last items best, and for later recall, only first items recalled well
question
visual encoding
answer
the encoding of picture images
question
acoustic encoding
answer
the encoding of sound, especially the sound of words
question
semantic encoding
answer
the encoding of meaning, including the meaning of words; produces better recognition of a word at a later time than does shallow processing by attending to its appearance or sound
question
self-reference effect
answer
phenomenon; we have especially good recall for info we can relate to ourselves
question
imagery
answer
mental pictures; a powerful aid to effortful processing, especially when combined with semantic encoding
question
rosy retrospection
answer
phenomenon where ppl tend to recall the high points hile forgetting the mundane moments; like ppl recalling events such as a camping holiday more positively than they evaluated them at the time
question
mnemonics
answer
memory aids, especially those techniques that use vivid imagery and organizational devices; "method of loci," "peg-word" system, acronyms
question
chunking
answer
organizing items into familiar, manageable units; often occurs automatically
question
hierarchies
answer
few broad concepts divided and subdivided into narrower concepts and facts; like outline format; efficient way to retrieve info
question
iconic memory
answer
a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second
question
echoic memory
answer
a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds adn words can still be recalled within 3 or 4 seconds.
question
working/short term memory
answer
short-term memories are limited in duration without active processing; also limited in capacity, as it typically stores just 7 or so bits of info
question
long-term memory
answer
our capacity for storing long-term memories is essentially limitless
question
long-term potentiation (LTP)
answer
an increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.
question
"cognitive enhancers"
answer
memory-boosting drugs; some boost production of the protein CREB, some glutamate (neurotransmitter that enhances synaptic communication (LTP)), etc.
question
stress hormones and memory
answer
stress hormones produced when excited or stressed make more glucose energy available to fuel brain activity; amygdala boosts activity in brain's memory-forming areas; strong emotional experiences make fore stronger memories; but prolonged stress can corrode neural connections and shrink hippocampus which is vital for laying down memories; also when sudden stress hormones are flowing, older memories may be blocked
question
amnesia
answer
the loss of memory; victims can't recall new facts or anything they've done recently, but they can still learn (without being aware that they're learning though)
question
implicit memory
answer
retention independent of conscious recollection. (Also called procedural memory). Learning how to do something
question
explicit memory
answer
memory of facts and experiences that one can consciously know and "declare" (also called declarative memory). Knowing and declaring that they know
question
hippocampus
answer
a neural center that is located in the limbic system and helps process explicit memories for storage; lateralized, one on L and R; active during slow-wave sleep; a temporary processing site for your explicit memories
question
cerebellum
answer
plays key role in forming and storing implicit memories created by classical conditioning
question
recall
answer
a measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test
question
recognition
answer
a measure of memory in which the person need only identify items previously learned, as on a multiple-choice test.
question
relearning
answer
a memory measure that assesses the amount of time saved when learning material for a second time
question
retrieval cues
answer
anchor points you can use to access the target information when you want to retrieve it later
question
priming
answer
the activation, often unconsciously, of particular associations in memory. Ask a friend two rapid-fire questions: (a) How do you pronounce the word spelled by the letters s-h-o-p? (b) What do you do when you come to a green light? If your friend answers "stop" to the 2nd Q, you have demonstrated priming; "memoryless memory"
question
deja vu
answer
that eerie sense that "I've experienced this before." Cues from the current situation may subconsciously trigger retrieval of an earlier experience.
question
state-dependent memory
answer
subtle phenomenon that states that what we learn in one state- be it joyful or sad, drunk or sober- is sometumes more easily recalled when we are again in that state
question
mood-congruent memory
answer
the tendency to recall experiences that are consistent with one's current good or bad mood
question
forgetting
answer
to discard the clutter of useless or out-of-date information; helpful; seven sins of memory
question
three sins of forgetting
answer
absent-mindedness (inattention to details produces encoding failure), transience (storage decay over time), blocking (inaccessibility of stored info)
question
three sins of distortion
answer
misattribution (confusing the source of info), suggestibility (the lingering effects of misinformation), bias (belief-colored recollections)
question
one sin of intrusion
answer
persistence (unwanted memories)
question
encoding failure
answer
age can affect encoding efficiency (age-related memory decline), and also without effort, many memories never form
question
forgetting curve
answer
by Ebbinghaus; indicates that much of what we learn we may indeed quickly forget; course of forgetting initially rapid, but then levels off with time
question
proactive interference
answer
the disruptive effect of prior learning on the recall of new information
question
retroactive interference
answer
the disruptive effect of new learning on the recall of old information; you can minimize it by reducing the # of interfering events (by sleeping shortly after learning new info, taking walk, etc.)
question
positive transfer
answer
when old information can facilitate our learning of new information
question
repression
answer
in psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories; but the submerged memory may be retrieved by some later cue or during therapy
question
misinformation effect
answer
incorporating misleading information into one's memory of an event; time, our guesses and assumptions, imagining, and others' vivid retelling of an event can implant false memories
question
source amnesia
answer
attributing to the wrong source an event we have experienced, heard about, read about, or imagined. (Also called source misattribution.) Source amnesia, along with the misinformation effect, is at the heart of many false memories.
question
discerning true and false memories
answer
memories are akin to perceptions; also because gist (meanings and feelings we associate w/ it) memories are durable, false memories may outlast true ones; confidence in eyewitnesses doesn't show accuracy; also "hypnotically refreshed" memories
question
cognitive interview technique
answer
asking less suggestive, more effective questions in interviews; to activate retrieval cues, detectives ask witnesses to visualize scene, and then ask evocative follow-up Q's
question
children's eyewitness recall
answer
nonleading questions can much improve their recall; leading and suggestive Q's plant false memories
question
"memory wars"
answer
intense controvery in 1990's; concerned claims of repressed and recovered memories of childhood sexual abuse; therapists used hypnosis, "guided imagery," and dream analysis; many criticized- adding to ppl's trauma and falsely accusing some adults; but both sides agree that injustice happens, incest and other sexual abuse happen, forgetting happens, recovered memories are commonplace, memories "recovered" under hypnosis or the influence of drugs are esp. unreliable, memories of things happening b4 age are also unreliable (infantile amnesia), and memories, whether real or false, can be emotionally upsetting
question
tips on improving memory
answer
study repeatedly to boost long-term recall; spend more time rehearsing or actively thinking about the material; make the material personally meaningful; to remember a list of unfamiliar items, use mnemonic devices; refresh your memory by activating retrieval cues; recall events while they are fresh, before you encounter possible misinfo; minimize interference; test your own knowledge, both to rehearse it and to help determine what you do not yet know.
