National Adult Reading Test
The NART comprises a list of 50 words printed in order of increasing difficulty. The words are relatively short in order to avoid the possible adverse effects of stimulus complexity on the reading of dementing subjects, and they are all 'irregular' with respect to the common rules of pronunciation in order to minimise the possibility of reading by phonemic decoding rather than word recognition.
The subject reads aloud down the list of words and the number of errors made is recorded. WAIS Verbal, Performance and Full-Scale IQs can be predicted from this reading error score by inserting it into the appropriate formulae.

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