recognition memory test TASK
Unreviewed

In a recognition memory test, a participant is presented with some or all of a set of "old" stimuli that were encoded earlier, as well as several "new" stimuli that were not previously presented. The participant's task is to indicate whether each stimulus is old or new. Responses in recognition memory tests are commonly sorted into four classes: Hits ("old" response to an old stimulus), Misses ("new" response to an old stimulus), False Alarms ("old" response to a new stimulus), and Correct Rejections ("new" response to a new stimulus). By comparing the percentage of responses that fall into each of these classes, the experimenter can assess both a participant's ability to discriminate between old and new stimuli, and his or her tendency to provide a particular response regardless of the type of stimulus presented. In many recognition memory tests, each old/new judgment is followed by a prompt asking participants to indicate either how confident they are in that old/new judgment, or what type of subjective experience was elicited by the stimulus being judged (e.g., was the old/new judgment accompanied by a vivid recollection of the encoding experience). This additional information can be used to generate and test more precise hypotheses about how recognition memory decisions are made.

Pattern Recognition Memory (PRM) is a specific recognition memory test included in the CANTAB. The participant is presented with a series of 12 visual patterns, one at a time, in the centre of the screen. These patterns are designed so that they cannot easily be given verbal labels. In the recognition phase, the participant is required to choose between a pattern they have already seen and a novel pattern. In this phase, the test patterns are presented in the reverse order to the original order of presentation.
This is then repeated, with 12 new patterns. The second recognition phase can be given either immediately or after a 20 minute delay.

CONDITIONS

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

CONTRASTS

You must specify conditions before you can define contrasts.


In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.

INDICATORS
response time
accuracy (number or percentage of correct identifications)

An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
