Question

Quizplus · Accepted Answer

Perceptual speed begins declining around age 25, as supported by longitudinal studies of aging and cognition. Spatial and verbal abilities do decline with age, but not necessarily rapidly, and the decline may vary among individuals. Numerical ability may also decline with age, but the evidence is not as clear-cut as for perceptual speed. Therefore, choice A is the most accurate option.
