AP Psych - Unit 1 Memory

acoustic encoding

The encoding of sound, especially the sounds of words.

Alzheimer's disease

A neurocognitive disorder marked by neural plaques, often with an onset after age 80, and entailing a progressive decline in memory and other cognitive abilities.

anterograde amnesia

A phenomenon in which a person suffers a brain injury from a stroke or an accident and loses the ability to form new memories since the injury.

automatic processing

The unconscious and effortless process of encoding information such as space, time, and frequency.

capacity of short-term memory

The magical number 7 plus or minus 2 (5-9 items).

central executive

In Baddeley's model of working memory, the component that coordinates processes of working memory, including the phonological loop and visuospatial sketchpad; it focuses attention, switches attention between different tasks, and initiates long-term encoding and retrieval.

chunking

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

cognition

The mental activities associated with thinking, knowing, remembering, and communicating.

context-dependent memory

Memories are more easily retrieved when one is in the same physical location in which those memories were encoded; for example, remembering events from 1st grade more easily when again in one's elementary school classroom.

deep encoding/processing

Mental activity that requires deliberation and control and involves a sense of effort, or overcoming resistance.

distributed practice

A learning procedure in which practice periods for a particular task are separated by lengthy rest periods or lengthy periods of practicing different activities or studying other material, rather than occurring close together in time. In many learning situations, distributed practice is found to be more effective than massed practice. Also called spaced learning; spaced practice.

duration of short-term memory

20 seconds to 20 minutes.

echoic memory

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

encoding

The processing of information into the memory system.

encoding failure

Failure to process information into memory.

episodic memory

The ability to remember personally experienced events associated with a particular time and place; in addition to recalling the facts of a past event, an individual has to engage in 'mental time travel' and remember that they were the one who lived the event. The hippocampus plays a key role in episodic memory formation and retrieval.

explicit memory

Memory of facts and experiences that one can consciously know and declare.

forgetting curve

A graphic depiction of the amount of forgetting over time after learning has taken place. There is generally a sudden drop in retention shortly after learning, followed by a more gradual decline thereafter.

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.

implicit memory

Memory for information that is acquired and expressed unconsciously or automatically via facilitated performance on a related task.

infantile amnesia

The inability to retrieve memories from much before age 3.

levels of processing model

Focuses on the depth of processing involved in memory, and predicts the deeper information is processed, the longer a memory trace will last; it includes structural, phonetic, and semantic processing.

long-term memory

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

maintenance rehearsal

Repeating items over and over to maintain them in short-term memory, although it does not effectively promote long-term retention because it involves little elaboration of the information to be remembered.

massed practice

multi-store model

Three stage memory model including sensory memory, short-term memory, and long-term memory.

phonological loop

A component that holds and manipulates auditory information over short intervals of time. For example, if one tried to remember a telephone number by repeating it over and over in the few moments before dialing, this effort would take place in the phonological loop.

recency effect

A memory phenomenon in which the most recently presented facts, impressions, or items are learned or remembered better than material presented earlier.

recognition

A measure of memory in which the person need only identify items previously learned due to the presence of retrieval cues.

rehearsal

The repetition of information, either to maintain it in consciousness or to encode it for storage.

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.

repression

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

retrieval

The process of getting information out of memory storage.

retrieval cues

Stimuli that help people retrieve memories; can be present in the external environment, such as sounds, smells, and sights, and can also be internal to the person retrieving the memory, such as physical states or feelings.

semantic encoding

Cognitive encoding of new information that focuses on its meaningful aspects as opposed to its perceptual characteristics.

semantic memory

A category of long-term memory that involves the recollection of ideas, concepts, and facts commonly regarded as general knowledge.

sensory memory

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

serial position effect

Our tendency to recall best the last and first items in a list.
