Q

Prospective memory

A

The ability to remember to perform actions in the future.

29
Q

Reality monitoring

A

The process of deciding whether memories are based on external sources (our perceptions of actual events) or internal sources (our thoughts and imaginations).

30
Q

Recall

test

A

A memory test that requires subjects to reproduce information on their own without any cues.

31
Q

Recognition

A

A memory test that requires subjects to select previously learned information from an array of options.

32
Q

Rehearsal

A

The process of repetitively verbalizing or thinking about information to be stored in memory.

Q

Relearning

A

A memory test that requires a subject to memorize information a second time to determine how much time or effort is saved by having learned it before.

34
Q

Repression

A

Keeping distressing thoughts and feelings buried in the unconscious.

35
Q

Retention

A

The proportion of material retained (remembered).

36

A

General knowledge that is not tied to the time when the information was learned.

43
Q

Semantic network

A

Concepts joined together by links that show how the concepts are related.

44
Q

Sensory memory

A

The preservation of information in its original sensory form for a brief time, usually only a fraction of a second.

45
Q

Serial-position effect

A

In memory tests, the fact that subjects show better recall for items at the beginning and end of a list than for items in the middle.

46
Q

Short-term memory (STM)

A

A limited-capacity store that can maintain unrehearsed information for about 20 to 30 seconds.

47
Q

Source monitoring

A

The process of making attributions about the origins of memories.

48
Q

Source-monitoring error

A

An error that occurs when a memory derived from one source is misattributed to another source.

49
Q

Storage

A

Maintaining encoded information in memory over time.

50
Q

Tip-of-the-tongue phenomenon

A

A temporary inability to remember something accompanied by a feeling that it’s just out of reach.

51
Q

Transfer-appropriate processing

A

The situation that occurs when the initial processing of information is similar to the type of processing required by the subsequent measures of attention.

52
Q

working memory capacity (WMC)

A

One’s ability to hold and manipulate information in conscious attention.
