a choice made between two or more options when one of those options has some probability >0 of producing either a reinforcing or an aversive consequence

choice task between risky and non-risky options has been asserted to measure the following CONCEPTS
as measured by the contrast:

CONDITIONS

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
earnings from choices
response time
number of risky choices

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).
