a collaborative knowledge base characterizing the state of current thought in Cognitive Science.
This task is composed of two conditions: hot and cold, with 27 rounds in each condition. In each round subjects are presented with 32 cards; some are gain cards, some are loss cards. Subjects are told how many points a gain card is worth, how many points a loss card costs, and how many loss cards there are in a round. Each round ends when a loss card is turned. In the cold version subjects choose how many cards they want to turn but don't see the result for the round until the end. In the hot version subjects click and turn each card themselves and sees their earning for that round. In both conditions, subjects see their final score at the end of 27 rounds.

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.


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).
