Research in the field of mental chronometry and individual differences has revealed several robust regularities (Jensen, 2006). These include right-skewed response time (RT) distributions, the worst performance rule, correlations with general intelligence ("g") that are more pronounced for RT standard deviations (RTSD) than they are for RT means…

SCORIT, a computer program which processes student responses to test items, is described and explained. The method of scoring responses according to an original test design and possible alternate test designs is detailed. The printing and punching of reports in a form suitable for correlational analysis are covered. A program description is…

This article compares two theories on why children with language impairment have slower response times when completing linguistic and nonlinguistic tasks. First, the slowing is due to difficulty with a particular cognitive processes and second, the slowing is due to a general cognitive processing limitation. Clinical implications are discussed.…
