A)A general slowing of central nervous system functioning fails to explain age-related declines in cognitive performance.

D)Crystallized factors show greater decrements than fluid factors.

Question

Quizplus · Accepted Answer

Research suggests that while there may be some declines in basic processing speed with age, these declines may not be significant enough to affect many well-practiced performances until later in life. Additionally, this general slowing of central nervous system functioning is not enough to fully explain all age-related declines in cognitive performance. Choices A and D are incorrect because research shows that both fluid and crystallized abilities may experience declines with age, but the degree to which each is affected may vary. Choice B is incorrect because research actually shows stability followed by declines in crystallized abilities.
