a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A task in which subjects are asked to perform a simple mathematical verification (e.g., 4/2 +1 = 3) and then read a word, with a recall test following some number of those verify/read pairs. The maximum number of words that can be recalled is the "operation span".

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).
