Subjects are presented with gambles in which they have a 50% chance of gaining some amount of money and a 50% chance of losing some other amount of money. The subject decides whether or not they would accept the gamble. The amount of the potential gain and loss are varied across trials. Gambles are not resolved during performance of the task; after the end of the task, some gambles are chosen at random and played for real money if they were accepted.

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.

response time

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).
