This study aims to examine the neural correlates of cognitive shifting during the task with functional near-infrared spectroscopy. Altogether 49 children completed the tasks, and 25 children (M = 68.66, SD = 5.3) passing all items were classified into the Switch group. Twenty children (M = 62.05, SD = 8.13) committing more than one perseverative errors were grouped into the Perseverate group. The Switch group had Brodmann Area (BA) 9 and 10 activated in the pre-switch period and BA 6, 9, 10, 40, and 44 in the post-switch period. In contrast, the Perseverate group had BA 9 and 10 activated in the pre-switch period and BA 8, 9, 10 in the post-switch period. The general linear model results afford strong support to the "V-shape curve" hypothesis by identifying a significant decrease-increase cycle in BA 9 and 44, the neural correlations of cognitive shifting.
本研究旨在利用功能近红外光谱技术研究任务执行过程中认知转换的神经关联。共有49名儿童完成了这些任务,其中25名通过所有项目的儿童(平均值=68.66,标准差=5.3)被归入转换组。20名出现不止一次持续性错误的儿童(平均值=62.05,标准差=8.13)被归入持续性组。转换组在转换前阶段激活了布罗德曼区(BA)9和10,在转换后阶段激活了BA 6、9、10、40和44。相比之下,持续性组在转换前阶段激活了BA 9和10,在转换后阶段激活了BA 8、9、10。一般线性模型结果通过识别BA 9和44中显著的下降-上升周期,即认知转换的神经关联,为“V形曲线”假说提供了有力支持。
