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).

"The performance of normal and aphasic subjects on a sentence-picture matching task shows that many different factors can affect accuracy. The data presented in this paper suggest that, for normal subjects, reversal errors are not errors of sentence parsing or comprehension, but reflect “late” stages of processing which mediate the translation between language and pictures. We argue that normal performance is significantly affected by the semantic or conceptual properties of the verbs used and by the interaction of verb meaning and sentence meaning. Aphasic errors, on the other hand, can arise from different sources and have multiple causes. We discuss data from three aphasic subjects who appear to have similar linguistic symptoms, and we argue that each patient fails on this task for different reasons."Citation Profile
