Simple and Choice Reaction Times in Schizophrenia
Archives of Neurology And Psychiatry, 1959In a recent study of simple and choice reaction times in patients with cerebral disease, it was found that simple reaction time differentiated brain-damaged and control patients quite as well as did choice reaction time. 1 Indeed, in a number of comparisons, simple reaction time appeared to be a somewhat more effective discriminator than choice ...

Hospitalization and Simple Reaction Time
Perceptual and Motor Skills, 1965Previous studies have raised the question of the validity of using only hospitalized Ss as controls when the results are generalized to a non-hospitalized population. Twelve male hospitalized Ss and 12 male non-hospitalized Ss participated in a reaction time study using the visual and auditory modalities under constant 6-, 9-, and 15-sec.

Journal of Gerontology, 1982
Although simple reaction time (RT) to a tone showed a statistically significant increase between 18 and 93 years of age in a sample of 220 men and women, the amount of increase was slight, less than 2 msec/decade. Consequently, the appreciable slowing of more typical behavior with age does not seen attributable to some general process in the central ...

Stimulus Probability and Simple Reaction Time
Nature, 1967SIMPLE reaction time tasks usually contain procedures designed to reduce or eliminate the frequency with which subjects anticipate the onset of the stimulus. These measures include varying the interval or foreperiod between the warning stimulus and the subsequent stimulus, and introducing a number of “catch trials” on which the stimulus does not follow

Response times and handedness in simple reaction-time tasks
Experimental Brain Research, 1996The anticipatory (preparatory) cerebral events in simple reaction-time tasks may depend on the ability of a subject to predict accurately the time of occurrence of the stimulus requiring a particular response. In order to examine this hypothesis, we recorded cerebral and muscle responses in two different conditions, each involving three simple reaction-

Influence of Hospitalization on Simple Reaction Time
Perceptual and Motor Skills, 1964Twelve hospitalized adult male patients' simple reaction time (RT), termination of a visual stimulus, was compared with that of 12 nonhospitalized adult males. Times between stimulus presentations (intertrial interval) were 3, 9, and 15 sec. A counterbalanced order of interval presentation was used.

Simple Reaction Time and Response Sets
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1966This study was concerned with the effects of induced response inhibition on simple visual reaction time. Ten Ss were confronted with up to four response alternatives (fingers of the right hand), one of which was the required response. Each of these responses was associated with a specific stimulus. Three response ensemble conditions were used: I—within

Simple reaction time: It is not what it used to be
The American Journal of Psychology, 2010Abstract This article calls attention to the large amount of evidence indicating that simple visual reaction time (RT) has increased. To show that RT has increased, the RTs obtained by young adults in 14 studies published from 1941 on were compared with the RTs obtained by young adults in a study conducted by Galton in the late 1800s ...

Electrodermal lability and simple reaction time
Biological Psychology, 1987Subjects identified as electrodermally labile or stabile (n = 10 per group) on the basis of non-specific electrodermal fluctuations and a trials-to-criterion measure of habituation were compared in a simple reaction time (RT) task that employed long, variable foreperiods (from 8 to 19 s). Labiles had significantly faster RTs across all foreperiods, but

Hemispheric interactions in simple reaction time
Neuropsychologia, 2002Fifty-eight normal subjects carried out a simple reaction-time task in which they responded unimanually to stimuli presented either singly in the left visual field, singly in the right visual field, or in both visual fields at once. The stimuli were white against a dark background on half the trials and gray against an equiluminant yellow background on
