When Does Cognitive Functioning Peak? The Asynchronous Rise and Fall of Different Cognitive Abilities Across the Life Span:
TL;DR: Convergent evidence from online participants and a comprehensive analysis of normative data from standardized IQ and memory tests reveal considerable heterogeneity in when cognitive abilities peak, which motivates a nuanced theory of maturation and age-related decline.

Abstract: Understanding how and when cognitive change occurs over the life span is a prerequisite for understanding normal and abnormal development and aging. Most studies of cognitive change are constrained, however, in their ability to detect subtle, but theoretically informative life-span changes, as they rely on either comparing broad age groups or sparse sampling across the age range. Here, we present convergent evidence from 48,537 online participants and a comprehensive analysis of normative data from standardized IQ and memory tests. Our results reveal considerable heterogeneity in when cognitive abilities peak: Some abilities peak and begin to decline around high school graduation; some abilities plateau in early adulthood, beginning to decline in subjects’ 30s; and still others do not peak until subjects reach their 40s or later. These findings motivate a nuanced theory of maturation and age-related decline, in which multiple, dissociable factors differentially affect different domains of cognition.

TL;DR: It is indicated that aging processes can be quantified in people still young enough for prevention of age-related disease, opening a new door for antiaging therapies.

Trajectories of normal cognitive aging.
TL;DR: Results from cross-sectional and quasi-longitudinal comparisons imply that normal cognitive aging is characterized by nearly linear declines from early adulthood in speed, and accelerating declines in memory and reasoning, and that vocabulary knowledge increased until the decade of the 60’s in all three types of comparisons.

A critical period for second language acquisition: Evidence from 2/3 million English speakers
TL;DR: A dataset of unprecedented size and a computational model provide the first direct estimate of how grammar-learning ability changes with age, finding that it is preserved almost to the crux of adulthood and then declines steadily.

TL;DR: A blood-DNA-methylation measure that is sensitive to variation in pace of biological aging among individuals born the same year is reported, called DunedinPoAm for Dunedin(P)ace(o)f(A)ging(m)ethylation.
Spatial navigation deficits — overlooked cognitive marker for preclinical Alzheimer disease?
Gillian Coughlan,Jan Laczó,Jakub Hort,Anne Marie Minihane,Michael Hornberger,Michael Hornberger +5 more
TL;DR: Spatial navigation is emerging as a potential cost-effective cognitive biomarker to detect AD in the preclinical stages, which has important implications for future diagnostics and treatment approaches.

Theoretical propositions of life-span developmental psychology : On the dynamics between growth and decline
TL;DR: In this article, a family of theoretical perspectives associated with this metatheoretical view of life-span developmental psychology includes the recognition of multidirectionality in ontogenetic change, consideration of both age-connected and disconnected developmental factors, a focus on the dynamic and continuous interplay between growth (gain) and decline (loss), emphasis on historical embeddedness and other structural contextual factors, and the study of the range of plasticity in development.
Abilities: their structure, growth, and action.
TL;DR: Herman et al. as discussed by the authors discuss what drives a person to or from the dinner table and the aspiring researcher who craves an area abounding with hypotheses begging to be tested, and find highly palatable food for thought.

Abilities: Their Structure, Growth, and Action
Abstract: analysis of a certain other primary drive. The serious researcher may discover something that he does not yet know, but that is not too likely. The obese will not discover the 'cure' that has so far eluded them. But the curious reader, he who wishes to gain a fairly detailed understanding of what 'really' drives him to or from the dinner table, and the aspiring researcher who craves an area abounding with hypotheses begging to be tested these will both find highly palatable food for thought.
