a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
The subject is presented with an array, then after a short delay, presented with a second array. In the no-change condition, the second array is identical to the first. In the change condition, the second array differs by a single item. Subjects must identify whether a change has occurred or not, and if so, are often asked to point out the change. Other versions target different sensory abilities, such as auditory change detection or face change detection.

CONDITIONS

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).
