Ignoring Task Irrelevant Information in Younger and Older Adults: An ERP Study

Older adults face a range of neuro-cognitive challenges as they age. One explanation for some of these challenges may be an increased difficulty in ignoring task irrelevant perceptual information as we age, leading to a cascade of later difficulties with cognitive tasks, such as working memory. Single-trial ERP's of top-down, task driven modulation of bottom-up sensory input in younger subjects has revealed large subject variability. We propose a single trial ERP study to look at possible task effects in a group of older and younger subjects.
