Influence of practice on visual reaction time
Journal of Mahatma Gandhi Institute of Medical Sciences, 2014 Background: The present study was aimed to see the effect of practice on visual information processing speed. Reaction time is one of the important physiological parameters, which gives information how fast and quickly person responses.

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.

Reaction Time and Visual Brightness: Within-Subject Correlations
Perceptual and Motor Skills, 1979 An 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.

Auditory Reaction Time and Visual Reaction Time in Asymptomatic HIV
, 2023 Background: 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 ...

ALPHA EEG PREDICTS VISUAL REACTION TIME [PDF]
International Journal of Neuroscience, 2006 Studies have suggested that consciousness is encoded discretely in time and synchronously in space of the brain. The present study was to model the alpha EEG as a brain clock to carry out the functions and to test whether the quality and rate of the oscillation could predict behavioral timing. Results showed that the alpha peak frequency was correlated

Reaction time and short-term visual memory [PDF]
Psychonomic Science, 1971 Posnefs method of using differences in RT for physical and name matches to estimate the time constant of visual STM is criticized as confounding the decay of the visual trace with the development of a name code. When this confounding is avoided by using stimuli that are hard to name (a 5 by 5 matrix of randomly filled squares), the time constant shown ...

A choice reaction time analysis of spatial frequency discrimination [PDF]
, 1989 Simple reaction time to the onset of sinewave gratings was measured as a function of spatial frequency in two observers. These results are compared to the choice reaction time required for the observer to correctly discriminate the spatial frequency of ...

Visual and auditory choice reaction times
Acta Psychologica, 1984 Abstract Choice reaction times are measured for three values of a priori signal probability with three well-practiced observers. Two sets of data are taken with the only difference being the modality of the reaction signal. In one set of conditions it is auditory, in the other, visual.

Inhibition of Return in the visual field [PDF]
, 2013 Inhibition of return (IOR) as an indicator of attentional control is characterized by an eccentricity effect, that is, the more peripheral visual field shows a stronger IOR magnitude relative to the perifoveal visual field.

Sit-and-Wait Strategies in Dynamic Visual Search [PDF]
, 2003 The role of memory in visual search has lately become a controversial issue. Horowitz and Wolfe (1998) observed that performance in a visual search task was little affected by whether the stimuli were static or randomly relocated every 111 ms.
