object-discrimination task
Unreviewed
Participants are shown pairs or sets of objects. Experimenters then try to discern whether the participant is able to discriminate between the objects. This can be done by having subjects match identical objects to each other, having certain objects become associated with rewards and measuring accuracy, or measuring time spent observing novel objects compared to time spent observing previously seen objects.

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
accuracy
time spent observing novel objects
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).
