Abstract

We investigated adult age differences in timing control of fast vs slow repetitive movements using a dual task approach Twenty two young (M = 24 23 yr) and 22 older adults (M = 66 64 yr) performed three cognitive tasks differing in working memory load and response production demands and they tapped series of 550 ms or 2100 ms target Intervals Single task timing was comparable in both groups Dual task timing was characterized by shortening of produced intervals and increases in drift and variability Dual task costs for both cognitive and timing performances were pronounced at slower tapping tempos an effect exacerbated in older adults Our findings implicate attention and working memory processes as critical components of slow movement timing and sources of specific challenges thereof for older adults
