Visual Search, Reaction Time, and Cognitive Ability

Perceptual and Motor Skills, 1998
The 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.

Visual reaction‐time versus action‐time

Ophthalmic and Physiological Optics, 1988
The 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, 1988
The 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, 2009
We 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 the

Visual Reaction Time

2020
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,

Visual Persistence as Measured by Reaction Time

Quarterly Journal of Experimental Psychology, 1972
Latency 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 ...

Attention and Visual Reaction Time in Schizophrenia

The Journal of Nervous and Mental Disease, 1981
Schizophrenic 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.

Reaction Times to Regularly Recurring Visual Stimuli

Perceptual and Motor Skills, 1964
In 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 Reaction Time in Normal and Handicapped Children

Perceptual and Motor Skills, 1969
Two 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.
