As people continue to live longer lives, the need to understand age-related cognitive change will increase. Understanding how older adults control their movements is one way to better understand how aging affects behavior. Research conducted by Welford, Norris, and Shock (1969) and Temprado et al. (2013) using a task to measure speed and accuracy demonstrated that as a human ages, the characteristics of their movements change. In particular, as compared with younger adults, older participants aged 60-79 showed a trend of reducing their movement speed while maintaining similar levels of accuracy across increases in task difficulty. Using a task to measure the speed and accuracy of participants over changes in the task difficulty, Coats and Wann (2011) suggested that older adults are more reliant on vision in order to complete a task that required accuracy in the placement of their movement endpoints. In the present study, older and younger adults used a computer mouse to move back and forth between two targets for 400 movements. The conditions included manipulations of visual information i.e., whether movement will occur in the presence or absence of visual feedback and difficulty. The results show that older adults were overall slower and less accurate than younger adults, but had less movement variability. ID and Vision were important for motor control, but the interactions with Group did not have a significant effect on motor control.
