A strong dependency between changes in fluid and crystallized abilities in human cognitive aging
Theories of adult cognitive development classically distinguish between fluid abilities, which
require effortful processing at the time of assessment, and crystallized abilities, which …

Intra-individual variability across fluid cognition can reveal qualitatively different cognitive styles of the aging brain
S De Felice, CA Holland - Frontiers in Psychology, 2018 - frontiersin.org
Dispersion is a measure of intra-individual variability reflecting how much performance
across distinct cognitive functions varies within an individual. In cognitive aging studies …

When does cognitive functioning peak? The asynchronous rise and fall of different cognitive abilities across the life span
JK Hartshorne, LT Germine - Psychological science, 2015 - journals.sagepub.com
Understanding how and when cognitive change occurs over the life span is a prerequisite

Greater lifestyle engagement is associated with better age-adjusted cognitive abilities
Previous evidence suggests that modifiable lifestyle factors, such as engagement in leisure
activities, might slow the age-related decline of cognitive functions. Less is known, however …

Two thirds of the age-based changes in fluid and crystallized intelligence, perceptual speed, and memory in adulthood are shared
Many aspects of cognition decline from middle to late adulthood, but the dimensionality and
generality of this decline have rarely been examined. We analyzed 20-year longitudinal data …

[HTML][HTML] Educational inequalities in aging-related declines in fluid cognition and the onset of cognitive pathology
Background Education has been robustly associated with cognitive reserve and dementia,
but not with the rate of cognitive aging, resulting in some confusion about the mechanisms of …
