Physiological evidence for response inhibition in choice reaction time tasks

open access: yesBrain and Cognition, 2004
Inhibition is a widely used notion proposed to account for data obtained in choice reaction time (RT) tasks. However, this concept is weakly supported by empirical facts. In this paper, we review a series of experiments using Hoffman reflex, transcranial

Choice reaction time with a random foreperiod [PDF]

open access: yesPerception & Psychophysics, 1983
Choice reaction latencies were measured at three different a priori probabilities for two stimulus alternatives. Unlike the results of some other studies, the mean latency of a given response was nearly the same whether the response was correct or incorrect. The discriminable stimuli were a 1000- or a 1700-Hz tone presented at 70 dB SPL.

Neurophysiological modulations in the (pre)motor-motor network underlying age-related increases in reaction time and the role of GABA levels – a bimodal TMS-MRS study

open access: yesNeuroImage, 2021
It has been argued that age-related changes in the neurochemical and neurophysiological properties of the GABAergic system may underlie increases in reaction time (RT) in older adults.

Manual choice reaction times in the rate-domain [PDF]

open access: yesFrontiers in Human Neuroscience, 2014
Over the last 150 years, human manual reaction times (RTs) have been recorded countless times. Yet, our understanding of them remains remarkably poor. RTs are highly variable with positively skewed frequency distributions, often modeled as an inverse Gaussian distribution reflecting a stochastic rise to threshold (diffusion process).

Reaction time and intelligence:Comparing associations based on two response modes [PDF]

open access: yes, 2013
People who score highly on intelligence tests also tend to have faster and less variable reaction times. Effect size estimates for the reaction time-intelligence association are larger in samples that are more representative of the population.

Single session of action observation in choice reaction time in healthy children

open access: yesMotriz: Revista de Educacao Fisica, 2021
Aim: Learning by action observation (AO) is a fundamental cognitive ability existing from birth either in live or in the video. However, the specific AO training, in live or in the video, can influence decision making and motor planning in healthy ...

On the predictor variable for choice reaction time [PDF]

open access: yesMemory & Cognition, 1974
A survey of published research using the Sternberg task was made for the period 1966 to early 1973. A majority of the data are better described by a linear equation involving log positive set size than by one involving set size per se as the scale of the predictor variable.

The effects of 6-weeks program of physical therapeutic exergames on cognitive flexibility focused by reaction times in relation to manual and podal motor abilities [PDF]

open access: yesBalneo and PRM Research Journal, 2023
The main purpose of the study was to identify the level of improvement in cognitive flexi-bility manifested by choice and cognition reaction times in relation to manual and podal skills as a result of the implementation of a program of therapeutic ...
