WebApr 7, 2024 · We tested a mechanistic account of the ‘neural noise’ hypothesis in a large adult lifespan cohort (Cam-CAN) with over 2500 adults (ages 18–102; 1508 female; 1173 male; 2681 behavioral sessions; 708 MRI scans) using WM fractional anisotropy (FA) to predict mean levels and variability in reaction time performance on a simple behavioral … WebInhibition, memory, temporal discounting, decision-making, timing, and intraindividual variability in reaction time have emerged as key cognitive domains for understanding neurocognitive deficits in individuals with ADHD. In the domain of inhibition, motor inhibition has been studied most extensively, with deficits demonstrated in both ...

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.

WebJun 15, 2024 · Neurophysiological work has associated larger neural variability during motor preparation with longer reaction time (RT) and larger movement variability, implying that movement variability decreases with increasing RT. Here, we recorded over 30,000 reaching movements in 11 human participants who moved to visually cued targets. WebFeb 1, 2008 · We refer to the variability of performance within one testing session as dispersion. Dispersion is typically assessed in reaction time experiments, where the distribution of reaction times over the testing session is used to … WebSep 1, 2024 · Reaction time variability is the trial to trial fluctuation in response time to a given task [7].
