Age differences in intra-individual variability in simple and choice reaction time: systematic review and meta-analysis [PDF]

, 2012
<p>Background: Intra-individual variability in reaction time (RT IIV) is considered to be an index of central nervous system functioning. Such variability is elevated in neurodegenerative diseases or following traumatic brain injury. It has also

Sprint Starts and the minimum auditory reaction time [PDF]

, 2007
The simple auditory reaction time is one of the fastest reaction times and is thought to be rarely less than 100 ms. The current false start criterion in a sprint used by the International Association of Athletics Federations is based on this assumed ...

Simple reaction time to the onset of time-varying sounds [PDF]

Attention, Perception, & Psychophysics, 2015
Although auditory simple reaction time (RT) is usually defined as the time elapsing between the onset of a stimulus and a recorded reaction, a sound cannot be specified by a single point in time. Therefore, the present work investigates how the period of time immediately after onset affects RT.

The Neurobehavioural Evaluation in Schizophrenics: A Comparative Study [PDF]

Journal of Clinical and Diagnostic Research, 2013
Background: The simple reaction time task assesses the ability of the subject to respond to an external cue and to retrieve a reward. The reaction time provides an indirect index of the processing capability of the central nervous system and a simple

Predicting Fluid Intelligence by Components of Reaction Time Distributions from Simple Choice Reaction Time Tasks

Journal of Intelligence, 2016
Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests.

Effect of glare on simple reaction time

Journal of the Optical Society of America A, 2008
We systematized the study of the effect of glare on reaction time (RT), for visual conditions similar to the ones found during night driving: Mesopic range of adaptation (0.14 cd/m2), glare levels of the order of those produced by car headlights (E(G)=15, 60 lx), suprathreshold luminance contrasts, and a variety of spatial frequencies covering the ...

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.

Reaction Time and Mortality from the Major Causes of Death: The NHANES-III Study. [PDF]

, 2014
Studies examining the relation of information processing speed, as measured by reaction time, with mortality are scarce.

Deary-Liewald Reaction time [PDF]

, 2016
Reaction time tasks are used widely in basic and applied psychology, including in much of the research carried out at CCACE. CCACE Director Ian Deary and Database Manager Dave Liewald have developed a new method of measuring reaction time that is an easy-

Psychomotor Retardation, Attention Deficit and Executive Dysfunctional in Young Non-hospitalised Un-medicated Non-psychotic Unipolar Depression Patients [PDF]

Journal of Clinical and Diagnostic Research, 2014
Background: Neuropsychological deficits have been reported in patients with Major Depressive Disorder (MDD) during an acute episode. The reaction time gives an idea about integrity and the processing ability of central nervous system.
