Taking a computational approach to aging: the SPAN theory of working memory
Article Abstract:
An alternative method on the computational theory of working memory in aging is through the speed, parallelism, activation and noise (SPAN) theory. The concept of information decay, displacement and processing speed affect the human working memory. SPAN is a production system consisting of the three mechanisms mentioned. The SPAN theory and related models give support for the computational adequacy of the slowing theory. There is evidence on the effect of slowing on the performance of various tasks and the cognitive system.

Genetic influences on memory performance in adulthood: comparison of Minnesota and Swedish twin data
Article Abstract:
A study of younger, middle-aged, and older twins using the univariate and multivariate genetic studies failed to show any differences in the heritability of memory efficacy across cohorts while differences were observed at the level of particular memory measures. Memory data from the Minnesota Twin Study of Adult Development and Aging was used in the study.

The heritability of cognitive functioning in very old adults: evidence from Danish twins aged 75 years and older
Article Abstract:
A study is presented which investigates the heritable influences on cognitive functioning in a sample of over 400 pairs of Danish twins aged 75 years and over. The results were seen to indicate significant genetic influences on cognitive functioning in late life.
