a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A task in which participants view stimuli (typically arrows) presented one at a time and to which they must make a simple lexical response. These stimuli are surrounded by either distracting or facilitating items. Distracting items are typically associated with an opposite response ("incongruent" = pointing in opposite direction to target stimulus), whereas facilitating items are typically associated with the same response as the target stimulus ("congruent" = pointing in the same direction as the target stimulus).

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


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.

response time

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).
