a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Subjects are presented with a set of stimuli and must classify those stimuli into one of two categories. In a common version known as the "weather prediction task" the stimuli are cards with geometric shapes on them and the outcomes are rainy versus sunny weather. The feedback is probabilistic, and performance is measured by the proportion of statistically optimal responses.

Classification learning and stop-signal (1 year test-retest)

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.

Proportion optimal responses
response time

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).
