【摘要】Objective To study the characteristic of 8 to 16-year-old 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.%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. 【总页数】2页(1017-1018)
