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).
"Note to other users: this is a complicated task with upwards of 26 contrasts, most of which are not included here. For complete contrasts, see the data in NeuroVault: http://neurovault.org/collections/101/ The image names, as well as the "cognitive atlas paradigm" and contrast will provide some detail to the other contrasts."
