Aging, cognitive resources, and declarative learning

Article Abstract:

Aging causes decrements in information-processing speed, working memory capability and declarative learning in adulthood. A study comparing a cross section of adults on various cognitive tasks reveals that working memory capability and processing speed are the resources mediating age differences in declarative learning. The contribution of working memory capability to declarative learning is much larger than that of processing speed.

An analysis of diversity in the cognitive performance of elderly community dwellers: Individual differences in change scores as a function of age

Article Abstract:

A study looked at age in association with increases in interindividual variability in ability domains from a sample of elderly community dwellers. Hierarchical regression analyses suggested that being female, with weaker muscle strength and greater symptoms of illness and depression were linked with overall greater variability in cognitive scores. Having a higher level of education was linked with reduced variability.

The "common cause hypothesis" of cognitive aging: evidence for not only a common factor but also specific associations of age with vision and grip strength in a cross-sectional analysis

Article Abstract:

Research indicates that the Common Cause Factor (CCF) is correlated not only with cognitive function in aging but also with grip strength and visual discrimination. Studies were conducted on subjects between 77.4 and 98.7 years of age, with cross-sectional categories for age, gender and apolipoprotein E.
