| Abstract: | Second-, fifth-, and ninth-grade students (8, 11, and 14 years of age, respectively) answered acoustic and semantic questions about words which were either congruent or incongruent with the questions. Subsequently, students' free recall of the words was unexpectedly tested. For words presented once in the list, only orienting task and congruity main effects were found. For twice-presented words, grade level interacted with both variables in that older students' recall was better than younger students' only for semantically encoded, congruent words. This finding is consistant with the hypothesis that developmental increases in semantic knowledge enhance the potential for encoding elaboration, but is in apparent conflict with the results of M. F. Geis and D. M. Hall (Child Development, 1978, 49, 857–861) who found no such interaction for second- and fifth-grade children. The different age spans included in the two studies provides one resolution of the discrepancy in results. However, a second experiment tested the importance of a procedural difference between the two studies. M. F. Geis and D. M. Hall (Journal of Experimental Child Psychology, 1976, 22, 58–66; 1978) presented the question after the stimulus word while we presented the question before the word. For ninth-grade students, the question after condition resulted in an attenuation of the recall difference between semantic and acoustic questions compared to the question before condition. It was argued that the pattern of developmental differences in incidental memory that is obtained may be related to which procedure is utilized. |
