A total of 81 toddlers (24-27months of age) participated in a biobehavioral investigation of inhibitory control. Maternal report measures of inhibitory control were related to laboratory tasks assessing inhibitory abilities under conditions of conflict, delay, and compliance challenge as well as toddler verbal ability. In addition, unique variance in inhibitory control was explained by task-related changes in brain electrical activity at lateral frontal scalp sites as well as concurrent inhibitory task performance. Implications regarding neural correlates of executive function during early development and a central organizing role of inhibitory processing during toddlerhood are discussed.
共有 81 名幼儿(24-27 个月大)参与了一项关于抑制控制的生物行为学研究。抑制控制的母体报告测量与实验室任务相关,这些任务评估了在冲突、延迟和顺从挑战条件下的抑制能力,以及幼儿的语言能力。此外,抑制控制的独特差异可以通过与任务相关的额侧头皮部位脑电活动的变化以及同时进行的抑制任务表现来解释。本文讨论了执行功能在早期发展中的神经关联以及抑制处理在幼儿期的核心组织作用。
