Which of the following is considered a problem in the evaluation of research on intelligence in later life?

Question

a. Inability of older adults to complete the intelligence measures
b. Lack of early childhood IQ test scores for comparison
c. Relevance of tasks used to measure adult cognitive functioning
d. Lack of other older adults to use as comparison groups

Answer 1

The problem often cited in the evaluation of research on intelligence in later life is:

b. Lack of early childhood IQ test scores for comparison

This issue arises because longitudinal studies that track individuals from childhood into later life may not have consistent early IQ test data available for all participants, making it difficult to assess how much intelligence may have changed over the lifespan.
