A neuropsychological test in which participants must connect-the-dots (traverse between items) according to some specified order. In Test A these items are numbers (1,2,3 etc.) and the order is determined by increasing magnitude. In Test B these items are both numbers and letters (1,2,3, A,B,C etc.) and the order is determined by a combination of increasing numbers AND letters (e.g., 1 A 2 B 3 C..) requiring participants to alternate between letters and numbers.

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
time to complete task

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).
