Q

Sensory memory

A

Memory systems that involve holding information from the world in its original sensory form for only an instant, not much longer than the brief time it is exposed to the visual, auditory, and other senses

Q

Working memory

A

A combination of components, including short-term memory and attention, that allow individuals to hold memory temporarily as they preform cognitive tasks; a kind of mental workbench on which the brain manipulates and assembles information to guide problem solving, understanding, and decision making

18
Q

Central executive (working memory)

A

Integrates information not only from the phonological loop and the visual-spatial sketchpad, but also from long term memory

19
Q

Long-term memory

A

A relatively permanent type of memory that stores huge amounts of information for a long time

20
Q

Explicit (declarative) memory

A

The conscious recollection of information, such as specific facts or events and, at least in humans, information that can be verbally communicated

21
Q

Episodic memory

A

The retention of information about where, when, and what of life’s happenings- that is, how individuals remember life’s episodes

22
Q

Semantic memory

A

A person’s knowledge about the world

23
Q

Implicit (nondeclarative) memory

A

Memory in which behavior is affected by prior experience without a conscious recollection of that experience

24
Q

Procedural memory

A

A type of implicit memory for skills

25
Q

Priming

A

The activation of information that people already have in storage to help them remember new information better and faster

26
Q

Schema

A

A preexisting mental concept or framework that helps people to organize and interpret information. Schemas from prior encounters with the environment influence the way individual encode, make inferences about, and retrieve information

27
Q

Retrieval

A

The memory process that occurs when information that was retained in memory comes out of storage

28
Q

Serial position effect

A

The tendency to recall the items at the beginning and the end of a list more readily than those in the middle

29
Q

Recall

A

A memory task in which the person must retrieve previously learned information, as on an essay test

30
Q

Recognition

A

A memory task in which a person must identify (recognize) learned items, such as multiple choice on a test

31
Q

Encoding specificity principle

A

States that information present at the time of encoding or learning, tends to be an effective retrieval cue

32
Q

Context dependent memory

A

The principle that people remember better when they attempt to recall information in the same context as when they learned (encoded) it

33
Q

Autobiographical memory

A

A special form of episodic memory, consisting of a person’s recollections of their life experiences

34
Q

Flashbulb memory

A

The memory of emotionally significant events that people often recall with more accuracy and vivid imagery than every day events

35
Q

Motivated forgetting

A

Forgetting that occurs when something is so painful or anxiety-laden that remembering it is intolerable

36
Q

Ebbinghaus forgetting curve

A

The principle that most forgetting occurs quickly after encoding, and then continues to decline as time passes

37
Q

Inference theory

A

The theory that people forget not because memories are lost from storage but because other information gets in the way of what they want to remember

38
Q

Proactive interference

A

Situation in which material that was learned earlier disrupts the recall of material that was learned later

39
Q

Retroactive interference

A

Situation in which material that was learned later disrupts the retrieval of information that was learned earlier

40
Q

Decay theory

A

Theory stating that when an individual learns something new, a neurochemical memory trace forms, but over time this trace disintegrates; suggests that the passage of time always increases forgetting

41
Q

Tip-of-the-tongue phenomenon

A

A type of effortful retrieval associated with a person’s feeling that they know something (say, a word or a name) but cannot quite pull it out of memory

42
Q

Amnesia

A

The loss of memeory

43
Q

Anterograde amnesia

A

A memory disorder that affects the retention of new information and events

44
Q

Retrograde amnesia

A

Memory loss for a segment of the past, but not for new events
