a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Subjects are presented with a sequence of three numbers in ascending order (20, 40, and 80). Each number is displayed onscreen for one second and, if the subject presses a button while that number is displayed, he/she receives that number of points along with immediate positive visual and auditory feedback. When a 40 or 80 appears, however, there is a chance that it will appear in an alternate color, along with immediate negative feedback signaling a loss of 40 or 80 points, respectively. When this occurs, the trial ends immediately (i.e. the subject may not make a response).

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).
