Researchers studying the volume of the hippocampus within the brain showed the importance of examining individual differences in aging by finding that:

Question

Quizplus · Accepted Answer

The research showed that at least some older adults had equal or higher brain volume than some young adults, emphasizing the importance of examining individual differences in aging. This contradicts the common assumption that brain volume decreases uniformly with age. Options A and B are incorrect because the study did not show that most adults 70 and older had greater hippocampal volume than younger adults or that the overall direction of hippocampal volume change was positive. Option D is incorrect because the study did not find that the greatest variation in hippocampal volume occurred among adults in their late 20s.
