Demonstrations that grip strength has predictive power in relation to a range of health
conditions—even when these are assessed decades later—has motivated claims that hand …

Increased intraindividual variability (IIV), reflecting within-person fluctuations in behavioral
performance, is commonly observed in aging as well as in select disorders including …

Cognitive development is known to involve improvements in accuracy, capacity, and
processing speed. Less is known about the role of performance consistency, and there has …

Background and Objective: Within-person variability in cognitive performance has emerged
as a promising indicator of cognitive health with potential to distinguish normative and …

Objective: Building on results suggesting that intraindividual variability in reaction time
(inconsistency) is highly sensitive to even subtle changes in cognitive ability, this study …

Type 2 diabetes mellitus (T2DM) is associated with a twofold increased risk of dementia and
can affect many cognitive abilities, but its underlying cause is still unclear. In this study, we …

Increased performance variability has been demonstrated in several groups and conditions,
including aging and cognitive decline. Structural brain characteristics underlying this …

Although not consistently replicated, a substantial number of studies suggest that left-
handers have larger callosal regions than right-handers. We challenge this notion and …

Aging and early-stage Alzheimer disease (AD) have been shown to be associated with
increased RT intraindividual variability (IIV, as reflected by the coefficient of variation) and an …

Manual dexterity measures can be useful for early detection of age-related functional
decline and for prediction of cognitive decline. However, what aspects of sensorimotor …
