Question

Quizplus · Accepted Answer

Research suggests that on average, older adults tend to score lower on intelligence tests than younger adults. However, this may not reflect their true intelligence as they have accumulated more knowledge and expertise over time. This phenomenon is known as the "crystallized intelligence" theory. Therefore, while older adults may score lower on traditional intelligence tests, they may actually be more intelligent than their scores indicate.
