AP Psych Unit 5 Part I

Recall

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

Encoding

the processing of information into the memory system—for example, by extracting meaning.

storage

the retention of encoded information over time

retrieval

the process of getting formation out of memory.

parallel processing

the processing of many aspects of a problem simultaneously; the brain's natural mode of information processing for many functions, including vision.

sensory memory

the immediate, very brief recording of sensory information in the memory system

short-term memory

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

long-term memory

the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences.

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

automatic processing

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

explicit memory

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

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

semantic encoding

the encoding of meaning, including the meaning of words

episodic

explicit memory of personally experienced events; one of our two conscious memory systems

flashbulb memory

a clear memory of an emotionally significant moment or event

LTP (long-term potentiation)

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

Priming

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

mood congruent

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 and first items in a list

anterograde amnesia

an inability to form new memories

retroactive interference

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

repress

the basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and 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

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

Concepts

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

prototype

a mental image or best example of a category

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

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

represetativeness 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

belief perseverance

clinging to one's initial conceptions after the basis on which they were formed has been discredited

Framing

the way an issue is posed; how an issue is framed can significantly affect decisions and judgments.

context effects

memory is aided by being in the physical location where encoding took place

phoneme

in language, the smallest distinctive sound unit

Morpheme

in a language, the smallest unit that carries meaning; may be a word or a part of a word (such as a prefix)

Syntax

Sentence structure

aphasia

impairment of language, usually caused by left hemisphere damage either to Broca's area (impairing speaking) or to Wernicke's area (impairing understanding).

Universal Grammar (Chomsky)

Noam Chomsky's theory that all the world's languages share a similar underlying structure

linguistic determinism (Whorf)

Whorf's hypothesis that language determines the way we think

self-reference effect

tendency to better remember information relevant to ourselves
