Inspection time and intelligence celebrating 25 years of research. (Editorial).
December 1, 2001... Twenty-five years ago, Nettelbeck and Lally (1976) described a significant correlation between inspection time and psychometric intelligence differences. That association is one of the most enduring findings concerning the cognitive processes...

On the heritability of inspection time and its covariance with IQ: a twin study.(Statistical Data Included)
December 1, 2001... 1. Introduction In an ongoing study of the genetics of cognition, in adolescent Australian twins, inspection time (IT) was collected as part of a psychometric battery to probe processing speed. The principal aim is to identify genetic...

Correlation between inspection time and psychometric abilities a personal interpretation.
December 1, 2001... 1. Introduction I will take a leaf from Ian Deary's excellent new book and begin at the end. Deary (2000) presents his conclusions in advance and invites the reader to evaluate what follows in the light of his comments. It is an apposite...

Developmental changes in inspection time: what a difference a year makes.(Statistical Data Included)
December 1, 2001... 1. Introduction While the speed of processing explanation for the correlation between inspection time (IT) and IQ in adults is now generally accepted (Deary & Stough, 1997; Kranzler & Jensen, 1989; Nettelbeck, 1987), just what IT...

Inspection time and the relationship among elementary cognitive tasks, general intelligence, and specific cognitive abilities.(Statistical Data Included)
December 1, 2001... 1. Introduction Since Nettlebeck and Lally's (1976) classic paper reporting the relationship between inspection time (IT) and general intelligence, one of the main goals of IT research has been to understand why IT predicts performance...

The functional anatomy of inspection time: a pilot fMRI study.(Magnetic resonance imaging)(Statistical Data Included)
December 1, 2001... 1. Introduction Individual differences in inspection time correlate about -.4 with performance-type measures of psychometric intelligence (Deary & Stough, 1996; Kranzler & Jensen, 1989). This is surprising because inspection time is a...

Examining neurochemical determinants of inspection time development of a biological model.
December 1, 2001... 1. Introduction 1.1. Overview Visual inspection time (IT) is defined as the minimum time an individual requires to reach near perfect response accuracy in a simple two-choice visual discrimination. Manipulating the time between...

Meta-analysis of the relationship between intelligence and inspection time.(Statistical Data Included)
December 1, 2001... 1. Introduction Results of Carroll's (1991) hierarchical factor analysis of a large battery of psychometric and chronometric tests led him to conclude "that the data strongly suggest that an important aspect of g is the speed and...

Inspection time past, present, and future. (Commentary).
December 1, 2001... It is my task to comment on the other papers in this special issue. I will attempt to indicate the ways in which they advance our understanding of fundamental issues. Twenty-five years ago, the discovery of a relationship between an...
