本研究采用近红外光谱法纵向比较了5岁和7岁儿童在空间工作记忆任务中额叶皮层的活动。8名儿童参加了两次研究，一次在5岁，一次在7岁。行为分析表明，年龄较大的儿童比年龄较小的儿童更准确、更迅速地执行工作记忆任务。近红外光谱分析表明，右半球优势，观察年龄较大的儿童，而没有半球的差异是明显的，在年幼的儿童。强化侧化的儿童表现出从5岁到7岁的改善。因此，我们提供了第一个演示的发展变化，额叶皮层激活空间工作记忆任务在学龄前期间。
This study longitudinally compared activity in the frontal cortex during a spatial working memory task between 5-year-old and 7-year-old children using near-infrared spectroscopy. Eight children participated in this study twice, once at 5 years and once at 7 years of age. Behavioral analysis showed that older children performed the working memory task more precisely and more rapidly than younger children. Near-infrared spectroscopy analysis showed that right hemisphere dominance was observed in older children, whereas no hemispheric difference was apparent in younger children. Children with strengthened lateralization showed improved performance from 5 to 7 years. We therefore offer the first demonstration of the developmental changes in frontal cortical activation during spatial working memory tasks during the preschool period.
