a computer-based task that requires participants to evaluate a battery of monochromatic “monostable” and “bistable” percepts and impaired performance on this task distinguishes those PD patients who experience VH. From: http://onlinelibrary.wiley.com/doi/10.1002/hbm.22321/full

CONDITIONS
No conditions have yet been associated.


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).
