Visual Reaction Time in Healthy Individuals

American Journal of Occupational Therapy, 2020
Date Presented 03/28/20 The study examined upper-extremity reaction times analyzed by five-year age cohorts to establish normative data for participants responding to stimuli on a touch screen and help delineate appropriate therapeutic intervention.

Effects of Acute Exercise on Visual Reaction Time

International Journal of Sports Medicine, 2008
We 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.

Flow-visualization by means of a time-reaction

Journal of Fluid Mechanics, 1963
A continuous-flow system is fed with a liquid which turns blue a specified time θ after entering. A more or less stationary pattern is thus set up, those parts of the liquid which have spent times longer than θ in the system being blue while the rest is colourless.

Visual Reaction Times on a Circle about the Fovea

Science, 1967
Reaction times to a dim photopic stimulus were measured on a circle about the fovea, 15° from the line of direct vision. Large variations in reaction time were found on various half meridians and were interpreted as reflecting the distribution of retinal receptors.

Laws of the simple visual reaction time.

Psychological Review, 1972
Fourteen 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 ...

Effects of Reaction Time on the Kinetic Visual Field

2011
Kinetic visual field refers to the visual range in which a moving target can be seen. The reaction time in traditional Kinetic Perimetry was the time from the target was identified to the subject responded, without taking into account individual simple reaction time (SRT). This is problematic in that it mixes the evaluations of human visual performance

Visual parameters impacting reaction times on smartwatches

Proceedings of the 18th International Conference on Human-Computer Interaction with Mobile Devices and Services, 2016
As a new generation of smartwatches enters the market, one common use is for displaying information such as notifications. While some content might warrant immediately interrupting a user, there is also information that might be important to display yet less urgent.

Mesopic visual efficiency II: reaction time experiments

Lighting Research & Technology, 2007
Reaction 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.

Choice Reaction Time: The Location of Auditory and Visual Similarity

The American Journal of Psychology, 1973
Each 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).

The simple reaction time to changes in direction of visual motion

Experimental Brain Research, 1999
Recently Dzhafarov et al. presented a model explaining data on simple reaction time (RT) to unidimensional velocity changes. The authors suggested that having a motion with an initial velocity V0, the velocity change detection system is reinitialized by means of a "subtractive normalization" process.
