Chronometric Tasks without Timed Response

As already noted, RT has two major aspects, the sensory and the motor, involving the afferent and efferent neural pathways and the complex network of connections between them in the brain. The RS sets off a physioloigical activity in the sensory and motor pathways and their neural connections that produce the final RT. If one side of this sensory-motor system is less closely related to the information-processing functions of the CNS than the other, it acts as an attenuating factor in the...

Correlations of Single Chronometric and Psychometric Variables

Typically, the smallest chronometric-psychometric (C-P) correlations are found between single C and P variables. This is particularly true for single C variables because they are usually much more homogeneous in content and cognitive demands than are P tests, which are invariably composed of a considerable number of varied items scored right or wrong for which the total score reflects a considerably broader factor than the score on a single C test. Increasing the number of trials given on a...

Mental Retardation

For a long period during the mid-1900s when chronometric research was at its lowest ebb in general experimental and psychometrics, its empirical revival in the late 1960s occurred in research on mental retardation (MR) in hopes of finding a more sharply analytic means of describing the nature of cognitive deficits than is afforded by conventional psychometric tests. The chief pioneers in this effort were Alfred Baumeister and co-workers. Their extensive empirical research on retardation is...

Chronometric Correlations with Conventional Mental Tests

That fact that chronometric measures are correlated with scores on PTs of mental abilities is now firmly established. Presently, active researchers in this field have reviewed much of this evidence from various theoretical perspectives and have drawn remarkably similar conclusions Caryl et al., 1999 Deary, 2000a, b Detterman, 1987 Jensen, 1982, 1985, 1987a, 1998, Chapter 8 Lohman, 2000 Neubauer, 1997 Vernon, 1987 . A true meta-analysis of all this evidence, however, is neither feasible, nor...

Experimental Variables and Procedures that Affect RT

The effects of the following variables are described here only in general terms of direction and magnitude. Specific quantitative values vary markedly with the nature of experimental conditions and of the subject sample, of which detailed descriptions would necessarily have to accompany any quantitatively precise conclusions. The various experimental conditions that are known to influence RT need to be taken into account in the design of any particular paradigm and apparatus for the measurement...
