Many studied reported that working memory components receive remarkable changes during lifespan. In order to better investigate this, we evaluated working memory components on human subjects belonging to five groups (10 subjects each) at different ages 6, 8 and 10 years old, young adult (age) and old adult (age). Our pattern of results shows a major transition in object sequence manipulation performance between ages 8 and 10 years. If related to young adults results, both 10-year-old children and old adults differed in accuracy and RT (specificare cosa significa) in both maintenance and manipulation conditions. In particular, young adults and old adults differ in RTs in the manipulation condition. Our results also suggest that a change in response strategy from 6 to 8 years of age, to prioritize accuracy may be present. Our findings appear consistent with recent neuroscientific findings, and lead to novel predictions.
许多研究报告称，工作记忆成分在整个生命周期中会发生显著变化。为了更好地研究这一点，我们对属于五组（每组10名受试者）不同年龄（6岁、8岁和10岁）的人类受试者、年轻成年人（年龄）和老年人（年龄）的工作记忆成分进行了评估。我们的结果模式显示，在8岁至10岁之间，对象序列操作表现发生了重大转变。与年轻成年人的结果相比，10岁儿童和老年人在维持和操作条件下的准确性和反应时间（明确说明其含义）均有所不同。特别是，年轻成年人和老年人在操作条件下的反应时间有所不同。我们的结果还表明，从6岁到8岁可能存在一种反应策略的变化，即优先考虑准确性。我们的发现似乎与最近的神经科学发现一致，并得出了新的预测。
