研究了潜在的反应抑制的控制过程。六名学生完成了视觉选择反应任务，偶尔会被呈现一种声音，告诉他们不要做出反应。反应时间的结果与假设反应激活和反应抑制过程之间的竞争的模型是一致的。事件相关脑电位、肌电和持续反应测量表明，反应可以在任何时候中断。有证据表明有两种抑制机制：抑制中枢激活过程和抑制运动指令从中枢到外周结构的传递。结果对控制过程和弹道过程之间的区别具有影响。(PulcINFO数据库记录(C)2017 APA，保留所有权利)
Control processes underlying response inhibition were examined. Six Ss performed a visual choice reaction task and were occasionally presented with a tone that told them to withhold the response. Reaction time results were in agreement with a model that assumes a race between response activation and response inhibition processes. Event-related brain potentials, electromyogram, and continuous response measures showed that responses could be interrupted at any time. Evidence was obtained for two inhibitory mechanisms: inhibition of central activation processes and inhibition of transmission of motor commands from central to peripheral structures. Results have implications for the distinction between controlled and ballistic processes.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
