Auditory startle reponse and reaction time
2009Recent experiments involving the use of a startling acoustic stimulus during a simple reaction time (RT) task have shown that premotor RT (PMT) can be significantly reduced when participants are startled (Valls-Sole et al., 1999; Carlsen et al., in press).

Simple Auditory Reaction Time in Blind and Sighted Adolescents
Perceptual and Motor Skills, 1979This study compared simple auditory reaction times of 20 subjects aged between 11 and 15 yr. ( M = 13), 10 born-blind from the Louis Braille Institut (Montréal) and 10 normal sighted subjects of the same age and sex. Their task was to press a telegraph key as fast as possible after presentation of an auditory stimulus.

Decreasing auditory Simon effects across reaction time distributions.
Journal of Experimental Psychology: Human Perception and Performance, 2016The Simon effect for left-right visual stimuli previously has been shown to decrease across the reaction time (RT) distribution. This decrease has been attributed to automatic activation of the corresponding response, which then dissipates over time. In contrast, for left-right tone stimuli, the Simon effect has not been found to decrease across the RT

Choice Reaction Time: The Location of Auditory and Visual Similarity
The American Journal of Psychology, 1973Each of eight subjects was visually presented four stimulus classes (pairs of letters combining high or low visual and high or low auditory similarity), each class at two locations of similarity (a pair of letters in a given class requiring the same or different responses).

Individual Differences in Auditory Reaction Time and Loudness Estimation
Perceptual and Motor Skills, 1968Three measures were computed for each of 32 undergraduate Ss: (1) the rate at which simple RTs to auditory stimuli decrease with sound-intensity, (2) the rate at which numerical estimates of loudness increase over the same stimulus range, (3) the mean of 60 RTs to a 70-db auditory stimulus.

Reaction Time of the Tongue to Auditory and Tactile Stimulation
Perceptual and Motor Skills, 1965Measures of reaction time of the tongue to tactile stimulation on the lips and to a 1000-cps tone at sensation levels of 10, 50, and 70 db were obtained from 26 normal young adults. Results revealed that tactile stimulation evoked the shortest reaction time ( M = .123 sec.); 70 db elicited slightly longer reaction time ( M = .129 sec.); 50 db still ...

Late visual and auditory ERP components and choice reaction time
Biological Psychology, 1993Some relations between different late positive ERP components and choice reaction time (RT) were studied. In order to identify the different components we used visual and auditory stimuli, as well as simple and choice reaction tasks, since one of the components is thought to be modality dependent and the other one task dependent.

Auditory and Visual Reaction Time in Adults during Long Performance
Perceptual and Motor Skills, 1987Better to understand the relation of auditory to visual reaction time (RT) tasks during a long period (320 min.) as well as the evolution of these performances along time, 24 subjects were tested. RT tasks were delivered at 10-min. intervals for 320 min. Correlations between auditory and visual RTs and cross-correlation functions were calculated.

Comparison of Electromyographic and Microswitch Measures of Auditory Reaction Time
Perceptual and Motor Skills, 1965The RTs of 3 Ss to clicks at 10, 30 and 90 db above their individually measured thresholds were obtained. It was concluded that use of a microswitch for signalling motor response introduces a significant delay in comparison with an electromyographic measure. Large reliable individual differences in amount of switch lag were found. Switch lag decreased

Relationships of Auditory and Visual Reaction Times to Reading Achievement
Perceptual and Motor Skills, 1968To determine the relationship between reading achievement and the reaction time of an individual responding to auditory and visual stimuli present in his perceptual field Ss were selected at random from Grades 2, 4 and 6. S lifted his finger from a key as rapidly as possible at the onset of any one of four stimuli (red or green light, high or low tone)
