Time Uncertainty and Choice Reaction Time

open access: yesNature, 1960
THE duration of the foreperiod, that is, the interval between some warning signal and the stimulus, has long since been known as one of the main factors which influence the length of simple reaction time2–4. Klemmer1 has recently shown that reaction time is shorter with brief (0.25 sec.) constant foreperiods than with either longer constant foreperiods

Variation of Reaction Time in Different Phases of Menstrual Cycle [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2013
Objective: To evaluate the influence of menstrual cycle on auditory and visual reaction times. Method: This study was conducted on thirty, healthy, regularly menstruating female subjects who were in the age group of 18- 25 years.

Immediate effect of Anulom Vilom (pranayama) on reaction time of 18-20 years’ age group

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2017
Background: Yogic techniques produce consistent physiological changes and have a sound scientific basis. There are lots of studies reporting the long-term effect of pranayama training, but there are few reports on the immediate effects of pranayama on ...

Perception of saccadic reaction time

open access: yesScientific Reports, 2020
That saccadic reaction times (SRTs) may depend on reinforcement contingencies has been repeatedly demonstrated. It follows that one must be able to discriminate one’s latencies to adequately assign credit to one’s actions, which is to connect behaviour ...

The Effect of Selected Exercise Programs on the Simple and Selective Reaction Time among Students with Development Coordination Disorder [PDF]

open access: yesRavānshināsī-i Afrād-i Istis̠nāyī, 2020
The purpose of this study was to investigate the effect of selected programs (including agility, speed, visual and auditory stimulation, mirror training, etc.) on the simple and choice response reaction time of children with developmental coordination ...

On the Properties of the Reaction Counts Chemical Master Equation [PDF]

open access: yes, 2019
The reaction counts chemical master equation (CME) is a high-dimensional variant of the classical population counts CME. In the reaction counts CME setting, we count the reactions which have fired over time rather than monitoring the population state ...

Effect of premenstrual stress on reaction time of 18-20 years age group

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2017
Background: The premenstrual syndrome is a recurrent, variable cluster of trouble some ill-defined symptoms and signs that develop during the 10 days before the onset of menses and subside when menstruation occurs.

Robust Stochastic Chemical Reaction Networks and Bounded Tau-Leaping [PDF]

open access: yes, 2009
The behavior of some stochastic chemical reaction networks is largely unaffected by slight inaccuracies in reaction rates. We formalize the robustness of state probabilities to reaction rate deviations, and describe a formal connection between robustness

Characterization of Turing diffusion-driven instability on evolving domains [PDF]

open access: yes, 2012
In this paper we establish a general theoretical framework for Turing diffusion-driven instability for reaction-diffusion systems on time-dependent evolving domains.

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

open access: yesJournal 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.
