The processing-speed theory of adult age differences in cognition.
TL;DR: A theory is proposed that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what are termed the limited time mechanism and the simultaneity mechanism.

Decomposing adult age differences in working memory.
TL;DR: In this paper, the authors investigate the contribution of three conceptually distinct aspects or components-processing efficiency, storage capacity, and coordination effectiveness, to age-related differences in measures of working memory.

Basal cortisol levels and cognitive deficits in human aging
Sonia J. Lupien,AndréRoch Lecours,Isabelle Lussier,G. Schwartz,N. P. V. Nair,Michael J. Meaney +5 more
TL;DR: Impaired cognitive performance was associated with recent evidence of hypothalamic-pituitary-adrenal (HPA) dysregulation and elevated basal cortisol levels and was consistent with recent animal studies showing the existence of subpopulations of aged rats that differ in HPA activity and cognitive performance.
