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.

Choice reaction time and the nature of the choice response [PDF]
Psychonomic Science, 1969 Difference between choice and simple RT (reaction time) was much smaller on a step-tracking task than on ungraded tasks having similarly direct stimulus-response mapping. Explanation of PR (psychological refractoriness) by noncon-gruent response organizations was thus supported.

Computational models of the Posner simple and choice reaction time tasks
Frontiers in Computational Neuroscience, 2015 The landmark experiments by Posner in the late 1970s have shown thatreaction time (RT) is faster when the stimulus appears in an expectedlocation, as indicated by a cue; since then, the so-called Posnertask has been considered a ``gold standard'' test of

Gap effect and reaction time distribution: simple vs choice manual responses
Brazilian Journal of Medical and Biological Research, 1998 It is well known that saccadic reaction times (SRT) are reduced when the target is preceded by the offset of the fixation point (FP) - the gap effect. Some authors have proposed that the FP offset also allows the saccadic system to generate a separate ...

Comparison of Motor Inhibition in Variants of the Instructed-Delay Choice Reaction Time Task. [PDF]
PLoS ONE, 2016 Using instructed-delay choice reaction time (RT) paradigms, many previous studies have shown that the motor system is transiently inhibited during response preparation: motor-evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS ...

Autocorrelation of choice-reaction times
Acta Psychologica, 1979 Abstract A choice-reaction (CR) task requires that the subject estimate, raking the warning signal or his response on the preceding trial as a reference point, the time when the reaction stimulus is due, so that he can begin deciding on his response at an appropriate time.

The effect of prediction accuracy on choice reaction time [PDF]
Memory & Cognition, 1989 In this study, we examined the effect of prediction accuracy on reaction time (RT). Subjects performed on three blocks of choice RT trials, all of which involved the mapping of four stimuli (red, green, 1, or 0) onto two response keys. The subjects were told that the four stimuli were equally probable and that their task was to respond to each stimulus

Dual task performance in normal aging: a comparison of choice reaction time tasks. [PDF]
PLoS ONE, 2013 This study examined dual task performance in 28 younger (18-30 years) and 28 older (>60 years) adults using two sets of choice reaction time (RT) tasks paired with digit tasks.
