The psychologist who studies changes in emotional maturity in the same 1000 people over many years uses a longitudinal approach, whereas someone who studies the emotional maturity of five different groups of people in five different age groups all at the same time in order to compare the groups' emotional maturity levels to each other uses a cross-sectional approach. Therefore, the best choice is A: longitudinal; cross-sectional. Option B is incorrect because there is no mention of an accelerated longitudinal approach. Option C is incorrect because it confuses the order of the two approaches. Option D is incorrect because it refers to a cross-sequential approach which is not mentioned in the question.
