Hierarchical Task
Unreviewed
The Hierarchical Reinforcement Learning Task measures participants’ ability to discover and use higher-order structure in their environment. Participants are presented with 18 stimuli composed of three dimensions: shape, orientation, and border color. The task requires that participants respond to stimuli by pressing one of three keys in response to each of the stimuli. In a "flat" condition, the keys are randomly associated with the shapes so that the participant must learn each association independently. In a "hierarchical" condition, the stimulus-response mappings are instead structured, such that participants can use a rule to determine the correct response based on the combination of the three features.

No associations have been added. 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
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).
