The effects of aging on reaction time in a signal detection task

Article Abstract:

A study is presented which investigates the influence of aging on response time, as demonstrated in signal detection tasks with young and older subjects. Older subjects were seen to generate slower response times than the younger subjects.

A diffusion model analysis of the effects of aging on letter discrimination

Article Abstract:

The effects of aging on accuracy and response time were examined in a letter discrimination experiment with young and older subjects. The results showed that older subjects were generally slower and less accurate than young subjects.

Aging, practice, and perceptual tasks: A diffusion model analysis

Article Abstract:

A diffusion model is used to characterize age differences in practice effects in a masked letter discrimination task and a masked brightness discrimination task between college-age and elderly people. The older subjects were slower to begin with but across sessions their accuracy improved and their performance for the brightness discrimination task was matched by that of the younger group illustrating that a well-specified model can provide a unified view of multiple aspects of data.
