摘要: Abstract Recent studies have proposed that rapid-speaking durations predict short-term memory spans. However, N. Cowan et al. (1998, Journal of Experimental Psychology: General, 127, 141–160) found two separate types processing related to digit span for children in Grade 1 (7–8 years), 3 (9–10 and 5 (11–12 years): (thought index the rate covert articulation) interword pauses task responses retrieval). The present analysis additionally establishes differential maturation those durations. Within-age correlations between were significant only first graders; pauses, fifth graders. When subsamples selected match spans across age groups, both duration also matched Grades 3. graders had considerably shorter than their third-grade counterparts. Thus, a particular is accompanied by different profiles rates ages.
