The Hungry Donkey Task is a version of Bechera's Iowa Gambling Task for children; it is a test in the areas of cognition & emotion that was originally developed to assist in detecting decision-making impairment in patients with prefrontal cortex damage. The experiment is often computerized and is carried out in real time and resembles real-world contingencies. A donkey chooses from four doors, each with a cost or reward in apples. The objective is to give the donkey the most apples possible.

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.


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).

User Discussion

"What does "accuracy" refer in the task contrast? there should probably be an indicator that specifies accuracy and how it is defined."
