The Big/Little Circle test assesses comprehension, learning and reversal. It is also intended to train participants in the general idea of following and reversing a rule, before proceeding to the Intra/Extradimensional Shift test (IED), so should ideally precede the IED task in a battery. Participants must first touch the smaller of the two circles displayed, then, after 20 trials, touch the larger circle for 20 further trials.

CONDITIONS

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
response time

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).
