a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A task in which stimuli are presented in a continuous stream and participants must detect the presence of an oddball stimulus. The oddball is a stimulus that occurs infrequently relative to all other stimuli, and has distinct characteristics (e.g., a different tone among auditory stimuli).

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


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.


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).
