Texting while walking is an increasingly common, potentially dangerous task but its functional brain correlates have yet to be reported. Therefore, we evaluated prefrontal cortex (PFC) activation patterns during single- and dual-task texting and walking in healthy adults. Thirteen participants (29-49 years) walked under single- and dual-task conditions involving mobile phone texting or a serial-7s subtraction task, while measuring PFC activation (functional near-infrared spectroscopy) and behavioral task performance (inertial sensors, mobile application). Head lowering during texting increased PFC activation. Texting further increased PFC activation, and decreased gait performance similarly to serial-7 subtraction. Our results support the key role of executive control in texting while walking.
边走路边发短信是一种越来越常见的潜在危险行为，但目前尚未有研究报告其大脑相关功能。因此，我们评估了健康成年人在单一任务和双重任务（边走路边发短信或进行连续 7 减 1 的减法任务）下的前额叶皮层（prefrontal cortex，PFC）激活模式。13 名参与者（年龄 29-49 岁）在单任务和双重任务条件下行走，任务包括使用手机发短信或进行连续 7 减 1 的减法任务，同时测量前额叶皮层的激活情况（功能近红外光谱）和行为任务表现（惯性传感器、手机应用程序）。发短信时头部下垂会增加前额叶皮层的激活。与连续 7 减 1 的减法任务相比，发短信进一步增加了前额叶皮层的激活，并降低了步态表现。我们的研究结果支持了执行控制在边走路边发短信中的关键作用。
