Since there are variations in the reaction times of athletes in different sports, the aim of the present study was to evaluate the effectiveness of a specific training program on a simple reaction time of male gymnasts. In this longitudinal study, fourteen adolescent gymnasts (mean age 12.6 ± 2.1 years) were randomly selected to work out for 15 months in the artistic group. Simple reaction ti...

I present a new approach for the interpretation of reaction time (RT) data from behavioral experiments. From a physical perspective, the entropy of the RT distribution provides a model-free estimate of the amount of processing performed by the cognitive system. In this way, the focus is shifted from the conventional interpretation of individual RTs being either long or short, into their distrib...

In this article, a method is presented to analyse relationships between detection or discrimination frequencies and reaction times in psychophysical tasks. It is shown in three empirical data sets that reaction time decreases as a linear function of the absolute value of the logit transforms of the response probabilities. Such a function stresses the characteristic uncertainty associated with s...

The RT (reaction time) to a 0.25 degree spot of light was measured monocularly on 25 normal subjects and 36 strabismic patients. The overall mean RT and the delta RT (difference in RT between the right and left eyes) for the 19 strabismic patients without amblyopia did not differ significantly from that of the normal subjects. The overall mean RT of the dominant eyes of the 17 amblyopic patient...

The spectral sensitivity of the eye was investigated using reaction times to broadband chromatic stimuli over a range of background luminances. Relative sensitivity was determined from the nonlinear reaction time curve by converting reaction times to a linear measure that was independent of spectral sensitivity. Two models for mesopic spectral sensitivity were compared. The first was a linear c...

Cantact placing reaction times were measured in cats which were either restrained in a hammock or supported in a conventional way. The reaction times were longer, particularly for the forelimbs, when the cats were tested in the hammock as compared to the conventional procedure. In both experimental situations reaction times were longer for the hindlimbs than for the forelimbs. Data for cats res...
