Jensen, A. R. – Intelligence, 2011
Mental chronometry (MC) studies cognitive processes measured by time. It provides an absolute, ratio scale. The limitations of instrumentation and statistical analysis caused the early studies in MC to be eclipsed by the "paper-and-pencil" psychometric tests started by Binet. However, they use an age-normed, rather than a ratio scale, which…

Smith, Glen A.; Stanley, Gordon – Intelligence, 1987
By comparing the profile of "g" loadings for a set of psychometric test scores, it is shown that general intelligence is related to timed performance measures from perceptual-motor tasks, more strongly on more complex tasks. The profile of the "g" loadings was predictable from the response-time (RT) psychometric test time correlations for four RT…

Little, Todd D.; Widaman, Keith F. – Intelligence, 1990
The analysis or modeling of Piagetian and psychometric measures of mental ability is discussed. An application of structural modeling procedures allowing the testing of hypotheses in this domain is presented. Such a model is illustrated through a study of numerical functional relations tasks with 77 elementary school students. (SLD)

Carroll, John B.; And Others – Intelligence, 1984
Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…
