Q

parallel processing

A

the processing of many aspects of a problem simultaneously; the brain’s natural mode of information processing for many functions, including vision. Contrasts with the step-by- step (serial) processing of most computers and of conscious prob- lem solving.

Q

long term potentiation (LTP)

A

Q

recall

Q

short term memory

A

Q

relearning

A

a measure of memory that assesses the amount of time saved when learning material again.

17
Q

working memory

A

a newer understanding of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory.

18
Q

priming

A

the activation, often unconsciously, of certain associa- tions, thus predisposing one’s perception, memory, or response.

19
Q

effortful processing

A

encoding that requires attention and con- scious effort.

20
Q

mood congruent memory

A

the tendency to recall experiences that are consistent with one’s current good or bad mood.

21
Q

automatic processing

A

unconscious encoding of incidental infor- mation, such as space, time, and frequency, and of well-learned in- formation, such as word meanings.

22
Q

serial positioning effect

A

our tendency to recall best the last (a recency effect) and first items (a primacy effect) in a list.

23
Q

anterograde amnesia

A

an inability to form new memories.

24
Q

implicit memory

A

retention independent of conscious recollection. (Also called nondeclarative memory.)

25
Q

retrograde amnesia

A

an inability to retrieve information from one’s past.

26
Q

iconic memory

A

a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second.

27
Q

proactive interefrene

A

the disruptive effect of prior learning on the recall of new information.

28
Q

echoic memory

A

a momentary sensory memory of auditory stim- uli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds.

29
Q

repression

A

in psychoanalytic theory, the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories.

30
Q

chunking

A

organizing items into familiar, manageable units; often occurs automatically.

31
Q

misinformation effect

A

incorporating misleading information into one’s memory of an event.

32
Q

mnemonics

A

any device or technique used to assist memory, usually by forging a link or association between the new information to be remembered and information previously encoded. For instance, one might remember the numbers in a password by associating them with familiar birth dates, addresses, or room numbers.

33
Q

source amnesia

A

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.

34
Q

spacing effect

A

the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice.

35
Q

deja vu

A

that eerie sense that “I’ve experienced this before.” Cues from the current situation may unconsciously trigger retrieval of an earlier experience.

36
Q

testing effect

A

enhanced memory after retrieving, rather than simply rereading, information. Also sometimes referred to as a retrieval practice effect or test-enhanced learning.
