Term
memory
Definition
the persistence of learning over time through the storage and retrieval of information
Term
encoding
Definition
processing of information into memory system- e.g.- extracting meaning
Term
storage
Definition
retention of encoded information over time
Term
retrieval
Definition
process of getting information out of memory storage
Term
sensory memory
Definition
immediate, very brief recording of sensory information in the memory system
Term
short-term memory
Definition
activated memory that holds a few items briefly, such as the 7 digits of a phone # while dialing, before the information is stored or forgotten.
Term
long-term memory
Definition
the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills and experiences
Term
connectionism
Definition
views memories as emerging from interconnected neural networks
Term
working memory
Definition
newer understanding of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of info retrieved from long-term memory
Term
parallel processing
Definition
processing of many aspects of a problem simultaneously; the brain's natural mode of information processing for many functions. Contrasts with serial processing of most computers and conscious problem solving
Term
automatic processing
Definition
unconscious encoding of incidental information, space/time/frequency, and of well learned information, such as word meanings.
Term
effortful processing
Definition
encoding that requires attention/conscious effort
Term
rehearsal
Definition
the conscious repetition of information, either to maintain it in consciousness or to encode it for storage. **Amount remembered depends on time spent learning
Term
spacing effect
Definition
the tendency for distributed study or practice to yield better long-term retention that is achieved through massed study or practice
Term
serial position effect
Definition
our tendency to recall best the last and first items in a list
Term
visual encoding
Definition
encoding of picture images
Term
acoustic encoding
Definition
encoding of sound (especially sound of words)
Term
semantic encoding
Definition
encoding of meaning, including meaning of words
Term
imagery
Definition
mental pictures; a powerful aid to effortful processing, especially when combined with semantic encoding
Term
mnemonics
Definition
memory aids, techniques that use vivid imagery and organizational devices.
Term
rosy retrospection
Definition
remembering high points, forgetting the mundane
Term
peg-word system
Definition
mnemonic device (jingle)
Term
chunking
Definition
organizing items into familiar, manageable units, often occurs automatically
Term
iconic memory
Definition
a momentary sensory memory of visual stimuli; a photographic or picture -image memory lasting no more than a few tenths of a second
Term
echoic memory
Definition
a momentary sensory memory of auditory stimuli; if attention is elsewhere; sounds and words can still be recalled within 3/4 seconds
Term
long term potentiation (LTP)
Definition
an increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.
Term
flashbulb memory
Definition
a clear memory of an emotionally significant moment or event.
Term
amnesia
Definition
loss of memory
Term
implicit memory
Definition
retention independent of conscious recollection (nondeclarative or procedural memory)
Term
explicit memory
Definition
memory of facts and experiences that one can consciously know and "declare" (declarative memory)
Term
hippocampus
Definition
a neural center that is located in the limbic system; helps process explicit memories for storage
Term
recall
Definition
a measure of memory in which the person must retrieve information learned earlier, (fill in the blank test)
Term
recognition
Definition
measure of memory in which person need only identify items previously learned, (multiple choice test)
Term
relearning
Definition
measure of memory that assesses the amount of time saved when learning material for 2nd time
Term
priming
Definition
the activation, often unconsciously, of particular associations in memory.
Term
deja vu
Definition
the eerie sense that "I've experienced this before." Cues from the current situation may subconsciously trigger retrieval of an earlier experience
Term
mood-congruent memory
Definition
the tendency to recall experiences that are consistent with one's current good or bad mood
Term
proactive interference
Definition
disruptive effect of prior learning on the recall of new information
Term
retroactive interference
Definition
distortive effect of new learning on the recall of old information
Term
repression
Definition
in psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings and memories
Term
misinformation effect
Definition
incorporating misleading information into one's memory of an event
Term
source amnesia
Definition
attributing to the wrong source an event we have experienced, heard about, read about, or imagined.
Term
source misattribution
Definition
source amnesia, along with the misinformation effect, is at the heart of many false memories
