Zimprich Psychology 2011 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 …
WebSep 1, 2024 · Reaction time variability is the trial to trial fluctuation in response time to a given task [7]. Reaction time variability is thought to occur due to fluctuations in the efficiency of neural networks supporting attention and executive functions [8], potentially due to vascular lesions (i.e. white matter hyperintensities) in the frontal lobe [9].
