Elijah Wong- UNIT 5 Vocab

working memory

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

explicit memory

memory of facts and experiences that one can consciously know and "declare"

effortful processing

encoding that requires attention and conscious effort

automatic processing

unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings

implicit memory

retention independent of conscious recollection

iconic memory

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

echoic memory

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

chunking

organizing items into familiar, manageable units; often occurs automatically

mnemonics

memory aids, especially those techniques that use vivid imagery and organizational devices

spacing effect

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

testing effect

enhanced memory after retrieving, rather than simply rereading, information

shallow processing

encoding on a basic level based on the structure or appearance of words

deep processing

encoding semantically, based on the meaning of the words; tends to yield the best retention

hippocampus

A neural center located in the limbic system that helps process explicit memories for storage.

flashbulb memory

a clear memory of an emotionally significant moment or event

long-term potentiation (LTP)

an increase in a cell's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory

recall

A measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test.

recognition

a measure of memory in which the person need only identify items previously learned, as on a multiple-choice test

relearning

a measure of memory that assesses the amount of time saved when learning material for a second time

priming

the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response

mood-congruent memory

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

serial position effect

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

anterograde amnesia

an inability to form new memories

retrograde amnesia

an inability to retrieve information from one's past

proactive interference

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

retroactive interference

the disruptive effect of new learning on the recall of old information

repression

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

misinformation effect

incorporating misleading information into one's memory of an event

source amnesia

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.

déjà vu

that eerie sense that "I've experienced this before." Cues from the current situation may subconsciously trigger retrieval of an earlier experience.

cognition

all the mental activities associated with thinking, knowing, remembering, and communicating

concept

a mental grouping of similar objects, events, ideas, or people

prototype

a mental image or best example of a category. Matching
new items to a prototype provide a quick and easy method for sorting items into categories

creativity

the ability to produce novel and valuable ideas

convergent thinking

narrows the available problem solutions to determine the single best solution

divergent thinking

expands the number of possible problem solutions (creative thinking that diverges in different directions)

algorithm

A methodical, logical rule or procedure that guarantees solving a particular problem.

heuristic

a simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms

insight

a sudden and often novel realization of the solution to a problem; it contrasts with strategy-based solutions

confirmation bias

a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence

mental set

a tendency to approach a problem in one particular way, often a way that has been successful in the past

intuition

an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning

representativeness heuristic

judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead us to ignore other relevant information

availability heuristic

estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common

overconfidence

the tendency to be more confident than correct—to overestimate the accuracy of our beliefs and judgments.
