TL;DR: In this paper, the authors suggest that communication among theorists and comparisons of theories may have been hampered in the past because only a subset of questions and criteria has typically been considered in the description and evaluation of theories.

TL;DR: Results from three studies are reported in which adults between 18 and 84 years of age performed various versions of the Digit Symbol Substitution Test, revealing that young and old adults appeared to use similar strategies to perform the task, and were nearly equivalent in the proportions of time devoted to writing the responses and searching the code table.

TL;DR: In this paper, the authors investigated the plausibility of the claim that increasing the processing demands in a memory task contributes to greater involvement of a central processor and the effects of altering reliance on the central processor on the magnitude of age-related differences in workingmemory tasks.

TL;DR: Support is provided for the hypothesis that a set of specific, age-invariant neural networks underlies these four RAs, and that these networks maintain their cognitive specificity and level of intensity across age.
