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.
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).
Definition contributed by MLewis about five years ago:participants see discs of various sizes distributed among three pegs and must organize them in a stack of decreasing size upward with specific constraints (i.e. only one disk can be moved at a time, each disk must be placed on one of the pegs, and a larger disk can never be placed on top of a smaller disk)REVISION 1
