Subjects are presented with a series of paired lottery choices. For example subjects choose between option A that is a lottery that wins $2 with probability 0.1 and $1.6 with probability 0.9 (safe bet) and option B that is a lottery that wins $3.85 with probability 0.1 and $0.1 with probability 0.9 (risky bet). The paired lottery choices are structured so that the crossover point to the high-risk lottery can be used to infer the degree of risk aversion.

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.
No contrasts have yet been associated.
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).
