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

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 ...

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.

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.

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.

Complexity of central processing in simple and choice multilimb reaction-time tasks. [PDF]

PLoS ONE, 2014
The default mode of the motor system is a coupling between limbs. However, in some movements, a decoupling is required and thus calls for selection and facilitation/inhibition processes.

The Effect of Limb Weight Gain on Premotor and Motor Components of Simple and Discriminative Reaction Time in Young and Elderly Men [PDF]

رشد و یادگیری حرکتی ورزشی, 2015
The effect of weight and force is one of the most important factors to organize and perform reaction time (RT) tasks. The elderly are involved in this variable when they gain weight.

Audio–visual Reaction Time in Different Age Groups in Normal Individuals: A Cross-sectional Study

Journal of the Scientific Society
Background: Reaction time (RT) is a simple yet sensitive measure of sensorimotor and cognitive processing. As life expectancy increases, understanding age-related changes in RT is essential to assess the functional implications of aging on everyday tasks

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...
