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 NPicchetti about six years ago:The pursuit rotor task is a task used in common use in the mid 20th century which involved a participant trying to follow (pursue) a small disc on a rotating turntable. Original mechanical versions had typical rotation rates of 60 RPM, which is probably too fast for mouse-controlled versions. The PEBL version offers a simple version with multiple trials and controllable parameters that can be used as a test of hand-eye coordination.REVISION 1
