WebJun 16, 2024 · Results are described in Figure 2. Note that average tactile reaction time for all subjects was 241 msec and visual reaction time was 329 msec. Inter-trial variability was used to calculate reaction time variability, and reaction time variability for the tactile task was much lower than it was for the visual task (16.8 msec vs. 80.7 msec). WebApr 4, 2024 · Reaction time variability (RTV), reflecting fluctuations in response time on cognitive tasks, has been proposed as an endophenotype for many neuropsychiatric disorders. There have been no large-scale genome wide association studies (GWAS) of RTV and little is known about its genetic underpinnings.
WebGreater cognitive ability in childhood is associated with increased longevity, and speedier reaction time (RT) might account for much of this linkage. Greater bodily symmetry is linked to both higher cognitive test scores and faster RTs. It is possible, then, that differences in bodily system integrity indexed by symmetry may underlie the associations of RT and … WebJan 1, 2024 · Inconsistency; Reaction time variability; Within-person variability Definition Intraindividual variability is broadly defined as the fluctuation in an individual’s cognitive performance over time.
WebWhile age effects in reaction time (RT) tasks across the lifespan are well established for level of performance, analogous findings have started appearing also for indicators of intra-individual variability (IIV). Children are not only slower, but also display more variability than younger adults in RT. Yet, little is known about potential moderating sex effects on RT-IIV.
WebSep 1, 2024 · Reaction time variability is the trial to trial fluctuation in response time to a given task [7].
