a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
Reaction Time (RTI) is a latency task with a comparative history (the five choice task) and uses a procedure to separate response latency from movement time. It is more useful than CRT or SRT where it is necessary to control for tremor. The task is divided into five stages, which require increasingly complex chains of responses. In each case, the participant must react as soon as a yellow dot appears. In some stages the dot may appear in one of five locations, and the participant must sometimes respond by using the press-pad, sometimes by touching the screen, and sometimes both.

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
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).
