a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A task in which a subject must attend and respond to two different tasks contained in one experimental run; one task is a feedback driven classification learning task in which a subject is presented with a stimuli (ex-geometric shapes) and has to classify them into one of two categories (ex-rainy or sunny weather), and then receives feedback on whether the response was correct or incorrect. The other task requires the subject to listen to different tones and count the number of a specific tone.

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
No indicators have yet been associated.


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).
