a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Participants view a configuration of dots and must indicate whether the dot is in the same position as the dot in the picture presented n previously (0,1,2,or 3). In some variations, participants are asked to identify the location of the dot n pictures back, rather than indicating if the current dot matches.

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.


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).
