摘要
工作记忆与认知能力、智力和学习能力有密切的联系。本研究采用横断研究的方法,测量了213名8岁到成年期被试的数字、词语和视空间工作记忆广度,探查了工作记忆广度的发展情况。结果发现,数字工作记忆广度在此期间持续增长,词语广度在18岁达到最高,视空间工作记忆广度在14-16岁达到高峰。不同任务的工作记忆广度具有相似的发展趋势,但工作记忆的平均广度分数与Pascual-Leone模型的预测并不一致。
213 subjects at each age (8, 10, 12, 14, 16,18 years old and adults) participated in this study. All subjects completed the following tests: backward digit recall, backward word list recall, spatial recall and visual recall. The results showed that working memory spans increased with age and peaked at different ages. The developmental trends of four tasks' memory span were similar. But the exact span-scores were different from what Pascual-Leone's model predicted.
