Publication: Psychol Rev
Authors: Salthouse TA
Publication year, pages: 1996;103: 403-428

Results, Conclusions and Implications: cognitive performance is degraded when processing is slow because relevant operations cannot be successfully executed (limited time) and because the products of early processing may no longer be available when later processing is complete (simultaneity).

Back to topAge differences in cognitive performance in later life: Relationships to self-reported
Publication: Journal of Gerontology
Authors: Hultsch, DF, Hammer, M, and Small, BJ
Publication year, pages: 1993; 48, 1?11
Sample Size: 484.
Results, Conclusions and Implications: individual differences in self-reported health and activity predicted performance on multiple cognitive measures. Additionally, self-reported health was more predictive of processing resource variables than knowledge-based abilities, interaction effects indicated that participation in cognitively demanding activities was more highly related to performance on some measures for older adults than for middle-aged adults.

Publication: Journal of the International Neuropsychological Society
Authors: Stern, Y
Publication year, pages: 2002; 8,448?460
Sample Size: --.
Results, Conclusions and Implications: Cognitive reserve may be based on more efficient utilization of brain networks or of enhanced ability to recruit alternate brain networks as needed. A distinction is suggested between reserve, the ability to optimize or maximize normal performance, and compensation, an attempt to maximize performance in the face of brain damage by using brain structures or networks not engaged when the brain is not damaged.
