a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
An alternative version of the AX-CPT in which the letter stimuli are replaced with simple dot patterns derived from Braille language. Dot patterns are more easily parametrically manipulated, and require less time between stimuli presentations because they are not as easily stored in working memory as letters, thus increasing the proportion of errors.
Synonyms: Dot Pattern Expectancy

CONDITIONS

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

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

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).
