摘要
目的较全面地了解8~16岁儿童短时记忆发展的特点和规律。方法采用横断研究的方法,选取8~16岁儿童共157名,测量了数字、词语、空间和位置短时记忆广度。结果8~16岁儿童不同任务的短时记忆广度随龄增加(F(4.145)=35.56,P〈0.01)。各任务短时记忆广度均于14岁达到高峰[数字(8.83±1.31)分、词语(4.79±0.68)分、空间(5.90±0.77)分、位置(5.42±1.28)分],14和16岁组之间差异无显著性。结论短时记忆的发展符合认知发展的基本规律,不同任务的短时记忆广度具有相同的发展趋势,但平均广度分数与Pascual-Leone模型的预测并不一致。
Objective To study the characteristic of 8 to 16-yearold children' s short-term memory. Methods 157 subjects participated in this study (8,10,12,14 and 16 years old). All subjects completed the digit recall, word recall, spatial recall and position recall tests. Results Short-term memory spans increased with age (F (4.145)=35. 56, P 〈 0.01 ) and peaked at 14 years old [digit (8.83±1.31), word (4.79±0.68), spatial (5.90±0.77) , position ( 5.42±1.28)].Conclusion The developmental trends of four tasks' memory span were similar. But the exact span-scores were different from what Pascual-Leone's model predicted.
