I want to see how well you can balance doing different things with your feet. I don’t want you to fall, however, so if you feel as if you are going to fall, please step off the line and use the wall for support. If at any time you feel that you can’t do these balance tests, please tell me and we will stop.
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).
