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

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).

Definition contributed by CTorgerson about six years ago: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

REVISION 2

Definition contributed by TSchonberg about seven years ago:on each trial, participants choose between a risky and safe option. The risky option is a lottery that offers a 50–50 chance of different outcomes (£10, £90 or £40, £60) and the safe option offers the participants’ own certainty equivalent for the corresponding risky lottery, as determined in a previous phase of the experiment. as in task described above, on each trial, participants choose between a risky and safe option. This time, possible outcomes of the risky option include (£10, £50), (£15, £45), (£40, £80) and (£30, £90), and the safe options offer a range of semi-random values.
