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.

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 ...

Spectral loudness summation and simple reaction time
The Journal of the Acoustical Society of America, 2004The present study evaluates the relation between loudness and simple reaction time (RT). Loudness matches between a narrowband noise (125 Hz wide) and a broadband noise (1500 Hz) were made at levels from near threshold to near 100 dB SPL. Over a similarly wide range of levels, RT to each of the noise bands was also measured.

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

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

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.

On the Peculiarity of Simple Reaction Time
The Quarterly Journal of Experimental Psychology Section A, 1990Two experiments are reported in which high-compatibility reaction time (RT) tasks were performed with, and without, a concurrent secondary task. In both experiments, the secondary task interfered to a greater extent with simple RT than with choice RT.

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

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 ...

Uncertainty, Timekeeping, and Simple Reaction Time
Journal of Motor Behavior, 1970Implications of the hypothesis that effects on simple RT of event and time uncertainty are due to S's unwillingness to prepare for an unlikely event were tested. In 2 experiments, RT was compared for the foreperiod method and the new transit-signal method. Alternative hypotheses based on faulty reinstatement of foreperiods were invalidated. The inverse
