Abstract
The purpose of this article is to introduce the inspection-time measure to the wider psychological community. Inspection time is, to date, the only single information-processing index that accounts for approximately 20% of intelligence-test variance. We argue that inspection time, because of its much-replicated correlation with IQ and its potential for theoretical tractability, has more potential for our understanding of individual differences in cognitive ability than other indexes of human information processing. The nature of inspection time and its measurement are described, studies correlating inspection time and IQ-type test scores are summarized, and the difficulties of explaining this correlation are highlighted.
