Göthe, Oberauer, and Kliegl (2007) compared younger and older adults in two tasks.One task was a visual-motor task in which participants had to mentally track the location of an arrow as it moved to various marked locations on a computer screen.The second task was a simple numerical task, that is, to add a number to a pre-existing sum every time the participant heard a tone.They found that:
A)older adults learned each task as well as the younger adults did, but had more difficulties when required to do the two tasks simultaneously.
B)older adults learned both tasks at slower rates than did the younger adults.
C)older adults were impaired on the visual-motor task because it requires the visual-spatial sketchpad, but not the numerical task.
D)older adults outperformed the younger adults because they were better able to allocate resources.
