Mounting evidence indicates that in healthy older adults,__________ predict(s)decrements in reaction time and other cognitive abilities.
A) faster information processing
B) extent of myelin breakdown
C) faster working-memory
D) increases in perceptual speed

Question

Quizplus · Accepted Answer

Myelin breakdown affects the speed and efficiency of neural transmission, which can lead to declines in cognitive abilities such as reaction time.

Answer: D 
 Perceptual speed refers to the ability to quickly and accurately process visual information, which is known to decrease with age and can affect reaction time and other cognitive abilities.
