Abstract

Task switching performance was assessed in a group of healthy young, healthy old, and MCI-diagnosed participants. Highly significant RT-related local switch costs were found in the MCI group. This contrasts the typical finding that in normal aging local switch costs show no age-related deficit. Local switch costs deficits may be a diagnostic tool in differentiating normal and pathological cognitive aging.

Keywords: Local switch costs; Mild cognitive impairment; Task switching.
