Abstract
An age-dependent answer-selection sequence was inferred from earlier studies (Powell, 1968, 1970, 1976 and 1977). These earlier studies suggested, from self-report, interview data, and distractors designed from logic errors, that content-independent thinking strategies (generalized procedures used to solve problems) were employed by students to select their answers to a multiple-choice test when they did not recognize the "correct" answer. The present study replicated the results of previous ones by capturing this developmental sequence using statistical rather than clinical means. The same multiple-choice reading-comprehension test (Gorham, 1956) used in some of these previous studies (Powell, 1968, 1976 and 1977) was administered twice to 2810 students aged 8- to 19+, with a five-month elapsed time between these two administrations. Using a statistical procedure based on the multinomial distribution to interpret single cells in the resulting contingency tables, this set of data was studied for evidence of this systematically-connected age-dependent sequence. It reappeared for all anticipated events within an error factor of less than five months.
