a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A measure of abstraction and mental flexibility. It is a multiple choice task in which the participant must conceptualize spatial, design and numerical relations that range in difficulty from very easy to increasingly complex [2]. During the PMAT, the participant must click with the mouse on the square he/she thinks best fits in the missing square of the pattern. There are three types of patterns made up of 2x2, 3x3 and 1x5 arrangements of squares. Each item has five response choices. Each PMAT form has 24 items and 3 bonus items. There are two forms, PMAT24-A and PMAT24-B. The test is arranged in order of increasing difficulty of items and is discontinued after the participant chooses an incorrect response for any five items. The bonus items are selected based on the participant’s performance. There are two forms, PMAT24-A and PMAT24-B. The test is arranged in order of increasing difficulty of items and is discontinued after the participant chooses an incorrect response for any five items.

Synonyms: PMAT24-A, PMAT

CONDITIONS
No conditions have yet been associated.


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

CONTRASTS
No contrasts have yet been associated.


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
No indicators have yet been associated.


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).
