Visual reaction‐time versus action‐time
Ophthalmic and Physiological Optics, 1988The reaction‐time for movement was found to be around 150 ms and was compared with the time required to take action while two moving lines are on a collision course. Subjects were trained to either avoid or maximize collision. They did so accurately. The action‐time was about one‐third the reaction‐time.

Sequential visual reaction times
Ophthalmic and Physiological Optics, 1988The reaction‐time to a series of successive digits was measured on two subjects. After practice, it was found that whilst the reaction time to the onset of the series was constant at 150 ms, the response time to additional digits became less and less to asymptote to a level of about 50 ms. The time course of this ‘chorus‐line’ phenomenon was studied in

Visual Reaction Time and Size Constancy
Perception, 2009We carried out six experiments to find out whether simple manual reaction time (RT) to flux-equated visual stimuli of different size is modulated by size constancy or by the retinal angle subtended by the stimuli. We found that RT decreased with the increase in perceived stimulus size rather than retinal angle and that this relationship depended on ...

This chapter discusses the theoretical foundations for, development of, empirical evidence for, and continued development of visual reaction time (VRT) as a measure of sexual interest. The evaluation of paraphilic sexual interests must adapt to scientific and technical advances, as well as to the cultural and societal attitudes, sociopolitical context,

Auditory Reaction Time and Visual Reaction Time in Asymptomatic HIV
2023Background: Auditory reaction time and visual reaction time were measured in asymptomatic HIV positive persons and corresponding controls to detect impaired central information processing mechanisms in the early stages of HIV. Objective: To perform auditory reaction time and visual reaction time in asymptomatic HIV positive persons and corresponding ...

Visual Reaction Time in Healthy Individuals
The American Journal of Occupational Therapy, 2020Abstract 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.

Attention and Visual Reaction Time in Schizophrenia
The Journal of Nervous and Mental Disease, 1981Schizophrenic behavior is sometimes characterized by inefficiency and symptoms possibly attributable to difficulties in coordinating attention. In fact, breakdown in cognitive and perceptual processes may be secondary to an initial disorder in mechanisms which coordinate focused attention.

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 ...
