risky lotteries task TASK
Unreviewed

Subjects choose between two lotteries (first published by Bruhin, Fehr‐Duda, & Epper (2010). Risk and Rationality: Uncovering Heterogeneity in Probability Distortion. Econometrica 78(4), 1375–1412, DOI: 10.3982/ECTA7139). Each lottery can yield one of two monetary outcomes (all positive outcomes, no losses). The range of magnitudes of the outcomes is {0,50}, the range of probabilities for each outcome {0,1}. Each lottery is displayed as a pie chart with the outcomes' probabilities represented by a shaded area of the pie and the magnitude displayed as a number in the respective area of the pie. Subjects are assumed to choose mostly the lottery with the higher subjective value.

CONDITIONS

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

CONTRASTS

You must specify conditions before you can define 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

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).
