In order to gauge the executive processes underlying adaptive behavior, a central criterion in psychology is the extent to which experimental findings generalize across response types. The latency of two major acts of control, action initiation and inhibition, was evaluated using a stop-signal paradigm with two response types, involving either a finger key-pressing or a wrist pen-swiping response. In both conditions, 40 participants were instructed to respond quickly to a GO stimulus but to cancel their responses when a STOP signal was presented, which occurred randomly in 25% of the trials. Taken together, analyses of reaction times and of inhibition probability functions indicated that action initiation generalized across the two response types. In contrast, the finger key-pressing and the wrist pen-swiping responses involved independent inhibition processes. These results challenge a strictly top-down view for some acts of control by showing an interaction between the executive and motor levels in terms of response modality specificity.
为了衡量适应行为背后的执行过程，心理学中的一个核心标准是实验结果在多大程度上可以推广到不同的反应类型。使用停止信号范式评估了两种主要控制行为（动作启动和抑制）的潜伏期，该范式有两种反应类型，分别涉及手指按键或手腕笔刷响应。在两种情况下，40 名参与者被指示快速响应 GO 刺激，但当出现随机出现的 25%试验中的 STOP 信号时，要取消响应。综合分析反应时间和抑制概率函数表明，动作启动可以推广到两种反应类型。相比之下，手指按键和手腕笔刷响应涉及独立的抑制过程。这些结果挑战了某些控制行为的严格自上而下观点，表明了执行水平和运动水平在反应模态特异性方面的相互作用。
