Old age is associated with poorer movement skill, as indexed by reduced speed and accuracy. Nevertheless, reductions in speed and accuracy can also reflect compensation as well as deficit. We used a manual tracing and a driving task to identify generalized spatial and temporal compensations and deficits associated with old age. In Experiment 1,…

Two experiments on divided attention and adult aging are reported that take into account age differences in single-task performance and that measure divided attention independently of resource allocation strategies. No significant age difference in divided attention ability independent of single-task performance level was found in either…
