本研究的目的是测试神经冲动的迹象与语音运动控制的年轻人与ADHD和健康的控制年轻人使用EEG记录在语音音高扰动范例。两组年龄匹配的年轻人提出了简短的音高变化的听觉反馈发声。音高变化的语音反馈引起了补偿行为和相应的生物电脑反应。生物电反应分析表明，ADHD组与对照组相比，运动相关生物电脑反应的峰值和起始潜伏期较短。这些结果被解释为表明多动症参与者和对照参与者之间执行功能的差异。我们推测，在本研究中发现的更快的运动相关的生物电反应可能是在不自主的语音控制水平的冲动在成人多动症的表现。
The present study was designed to test for neural signs of impulsivity related to voice motor control in young adults with ADHD and healthy control young adults using EEG recordings in a voice pitch perturbation paradigm. Two age-matched groups of young adults were presented with brief pitch shifts of auditory feedback during vocalization. Compensatory behavioral and corresponding bioelectrical brain responses were elicited by the pitch-shifted voice feedback. The analysis of bioelectrical responses showed that the ADHD group had shorter peak and onset latency of motor-related bioelectrical brain responses as compared to the controls. These results were interpreted to suggest differences in executive functions between ADHD and control participants. We hypothesize that more rapid motor-related bioelectrical responses found in the present study may be a manifestation of impulsiveness in adults with ADHD at the involuntary level of voice control.
