a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
A measure of abstraction and concept formation by hypothesis testing, where the principle shifts after its discovery is established.. Subjects decide which of 4 objects does not belong with the other 3 based on one of three sorting principles (e.g., shape, size, line thickness). Sorting principles change after 10 successive correct responses, and feedback is used to guide discovery of the principle and indicate its change. There are 4 alternate forms available. An accuracy score is calculated by multiplying the proportion of correct responses by the number of categories attained (out of 3 possible).

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


You must specify conditions before you can define 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.


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).
