a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Subjects view various visual stimuli and make no response. Stimuli include houses, faces, objects, fractals, letter strings, line drawings, complex scenes, etc. If the presented stimuli were faces, the experiments are co-coded with Face Monitor/Discrimination. But if the presented stimuli are words, the experiments are not coded as passive viewing but rather as reading (covert).

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.


You must specify conditions before you can define 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.

BOLD activity
areas of activation

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).
