Mesopic visual efficiency II: reaction time experiments
Lighting Research & Technology, 2007Reaction times are recorded to chromatic, mesopic stimuli to investigate mesopic reaction time spectral sensitivity. Measurements are made using three laboratory setups and a driving simulator. The chromatic stimuli have spectral distributions that range from quasi-monochromatic to broadband. Reaction time spectral sensitivity for small (0.29°) foveal

Reaction Times to Regularly Recurring Visual Stimuli
Perceptual and Motor Skills, 1964In this experiment, which was concerned with reaction times to regularly recurring visual stimuli, four experienced Ss made 21 serial responses at eight interstimulus intervals with eight replications each. The experiment was designed to provide answers to the following questions.

Visual Persistence as Measured by Reaction Time
Quarterly Journal of Experimental Psychology, 1972Latency of reaction to onset of a visual display was subtracted from latency of reaction to offset. Persistence was defined as difference between the two latency values. Persistence was inversely related to stimulus duration and was comparable for monoptic presentation and for presentation of the first half of the stimulus duration to one eye and the ...

Visual Reaction Time in Normal and Handicapped Children
Perceptual and Motor Skills, 1969Two groups of children, 6 trainable mental retardates and 6 normals, matched for MA, were tested on a simple reaction time task, using onset of a light. Support for the hypothesized RT difference in favor of the normals was obtained. The study confirms data from older retarded groups.

Lighting for road tunnels: The influence of CCT of light sources on reaction time
Displays (Guildford), 2020Drivers’ visual performance is closely related to traffic safety in a real driving environment. In order to improve the traffic safety of road tunnel lighting, the effect of LED lighting on human visual performance was investigated using reaction time as

Effects of Acute Exercise on Visual Reaction Time
International Journal of Sports Medicine, 2008We examined the effects of acute exercise on reaction time to visual stimuli presented in the central portion and periphery of the visual field. Twelve participants performed reaction time tasks at rest and during cycling at 65 % peak oxygen uptake in two visual conditions. We used circular black-and-white checkerboard patterns as visual stimuli.

Visual Search, Reaction Time, and Cognitive Ability
Perceptual and Motor Skills, 1998The contributions of visual search to reaction time and cognitive ability were investigated with 45 subjects. Visual search was assessed via eye movements. The electrooculogram was recorded while a subject located letters arranged in a large display. Reaction time was obtained for a search task. A reasoning and a space scale served to assess cognitive

Laws of the simple visual reaction time.
Psychological Review, 1972Fourteen studies from the literature on the reaction time (RT) to a flash of light provided sufficient methodological detail and data to allow for a quantitative analysis of the effects of the following selected variables: luminance, duration, size of stimulus, response to onset versus termination of the signal, and monocular versus binocular viewing ...

Reaction Time and Visual Brightness: Within-Subject Correlations
Perceptual and Motor Skills, 1979An experiment was conducted to compare visual reaction time and visual brightness within the same subjects. Simple reaction times and magnitude estimates of brightness were obtained in response to 1000-msec. flashes of 60.7, 67.5, 76.4, 85.1, and 93.4 dB re 10−10L white light.

Visual Simple Reaction Time in Cyanotic Heart Disease
Archives of Pediatrics & Adolescent Medicine, 1967CHILDREN with acquired or congenital cerebral defects accompanied by obvious motor impairment, such as cerebral palsy, have slower performance speed by virtue of their neurologic damage. Prolonged, severe hypoxia of the central nervous system has been shown to lead to profound physiologic and psychologic changes in the organism.
