Slowness and age: speed-accuracy mechanisms

Article Abstract:

Age differences in motor performance were examined. Younger and older subjects were asked to perform a serial four-choice reaction time task and their performances were compared after 2,000 trials. Older subjects' accuracy rate was similar to younger adults' and both groups had the same reaction time. However, older subjects were slow to respond to the very fast, high-error part of the conditional accuracy function. They were more cautious and unlike younger subjects, they did not push themselves to their limits.

Cognitive decline in old age: Separating retest effects from the effects of growing older

Article Abstract:

Study was conducted to examine the issue that repeated administration of cognitive tests improves test performance, making it difficult for researchers to gauge the true extent of age-related cognitive decline. It was found that retest-based improvement in cognitive test performance could be substantial and persistent.

Experience-based attenuation of age-related differences in music cognition tasks

Article Abstract:

Issues concerning the study of experience and its influence on age-cognition relations are discussed. The musical memory and perceptual speed of a group of pianists of varied age and experience were examined and the results are presented.
