The n-back task is likely the most popular measure of working memory for functional magnetic resonance imaging (fMRI) studies. Despite accumulating neuroimaging studies with the n-back task and children, its neural representation is still unclear. fMRI studies that used the n-back were compiled, and data from children up to 15 years (n = 260) were analyzed using activation likelihood estimation. Results show concordance in frontoparietal regions recognized for their role in working memory as well as regions not typically highlighted as part of the working memory network, such as the insula. Findings are discussed in terms of developmental methodology and potential contribution to developmental theories of cognition.
n-back 任务可能是功能磁共振成像 (fMRI) 研究中最常用的工作记忆测量方法。尽管使用 n-back 任务进行了越来越多的神经影像学研究，但它的神经表现仍不清楚。编译了使用 n-back 的 fMRI 研究，并使用激活似然估计分析了年龄在 15 岁以下的儿童(n=260)的数据。结果表明，在工作记忆中起作用的额顶叶区域以及通常不作为工作记忆网络一部分的区域（如脑岛）具有一致性。研究结果从发展方法论和对认知发展理论的潜在贡献两方面进行了讨论。
