IMPLEMENTATIONS of WRAT-4 Math Computation
Implementation #1 The fourth edition of this classic test measures the basic academic skills—reading, spelling, and mathematical computation—necessary for effective learning, communication, and thinking. This version features an entirely new subtest, Sentence Comprehension, to enhance the scope of the test and to meet the need for a measure of reading comprehension.

No conditions have yet been associated.

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.

No contrasts have yet been associated.

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).
