During the foreperiod (FP) of a warned reaction task, participants engage in a process of temporal preparation to speed response to the impending target stimulus. Previous neurophysiological studies have shown that inhibition is applied during FP to prevent premature response. Previous behavioral studies have shown that the duration of FP on both the current and the preceding trial codetermine response time to the target. Integrating these findings, the present study tested the hypothesis that the behavioral effects find their origin in response inhibition on the preceding trial. In two experiments the variable-FP paradigm was combined with a go/no-go task, in which no-go stimuli required explicit response inhibition. The resulting data pattern revealed sequential effects of both FP (long or short) and response requirement (go or no-go), which could be jointly understood as expressions of response inhibition, consistent with the hypothesis.
在预警反应任务的预备期（FP），参与者进行时间准备，以加快对即将到来的目标刺激的反应。先前的神经生理学研究表明，在 FP 期间应用抑制作用，以防止过早反应。先前的行为研究表明，当前和前一个试验的 FP 持续时间共同决定了对目标的反应时间。综合这些发现，本研究检验了这样一种假设，即行为效应起源于前一个试验的反应抑制。在两项实验中，可变 FP 范式与 Go/No-Go 任务相结合，其中 No-Go 刺激需要明确的反应抑制。所得数据模式揭示了 FP（长或短）和反应要求（Go 或 No-Go）的顺序效应，这可以共同理解为反应抑制的表达，与假设一致。
