Peripheral Area-Intensity Interaction in Scotopic Visual Reaction Time

Optometry and Vision Science, 1977
Two observers performed simple reaction-time responses to peripheral stimuli of varying intensity (-2.5 to +1.0 log td) and angular subtense (10 to 210 min). The area-intensity combinations that produced each of three scotopic reaction-time criteria were calculated.

Visual reaction time of cats to different spatial frequencies

Visual Neuroscience, 1990
AbstractIf physiological mechanisms similar to cat Y and X cells explain faster detection of low spatial frequencies by humans, then cats should show the same effect. We have tested this prediction by determining the visual reaction time of cats over a range of spatial frequencies and contrasts by training them to respond quickly when a vertical sine ...

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.

Peripheral area-intensity interaction in simple visual reaction time

Vision Research, 1974
Abstract Two O s performed simple reaction-time responses to peripheral stimuli of varying intensity (− 2.5 to + 3.8 log td) and angular subtense (10–156 min). The area-intensity combinations were calculated which produced each of several criterion reaction times.

Relationship between directed visual attention and saccadic reaction times

Experimental Brain Research, 1988
Saslow (1967) and Fischer and Ramsperger (1984) found that saccadic reaction time (SRT) depends on the interval between the fixation point offset and the target onset. Using a continuously visible fixation point, we asked whether a similar function would be obtained if subjects attended to a peripherally viewed point extinguished at variable intervals ...

Moving and Nonmoving Visual Stimuli: A Reaction Time Study

Perceptual and Motor Skills, 1969
Various considerations suggest that the perception of movement may be mediated at either of two levels, retinal or central, depending on characteristics of the stimulus. Under such a scheme the mediation of apparent movement should be central. One experiment implies that apparent movement may be coded as movement at the retinal level.

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.
