本研究旨在探讨在前一个试验中对危险物体的准备反应加工是否会影响随后的试验加工。设计对当前试验的Go/NoGo因子、前一试验的目标危险性和当前试验的目标危险性进行了操纵。在当前的围棋试验中，行为结果显示，在安全试验之前的试验中存在典型的运动干扰效应（与之前安全和当前安全（sS）条件相比，之前安全和当前危险（sD）条件的反应时间（RT）更长，错误率更大）。然而，在之前进行危险试验的试验中，运动干扰效应减弱（前危险和当前危险（dD）条件与前危险和当前安全（dS）条件之间的平均RTs和错误率差异不显著）。事件相关电位（ERP）结果发现，与dS相比，dD条件下的P2和顶叶P3波幅（表明注意资源分配）更积极。sD组的P2和P3峰幅值与sS组无显著差异。这些结果支持了先前试验中由危险目标引起的回避动机可能表明危险情况的假设，这导致更多的注意力资源被分配到随后的危险试验中。因此，在连续的危险条件下，RTs得到改善，误差减少，随后在危险试验之前的试验中，与安全试验之前的试验相比，运动干扰效应降低。然而，对当前NoGo试验的分析显示，在行为和ERP结果中，没有一个主要影响或相互作用达到显著性，这表明只有在需要执行准备好的反应时，假设才成立。
This study aims to investigate whether processing a prepared response toward a dangerous object in a previous trial influences subsequent trial processing. The design manipulated the Go/NoGo factor of the current trial, the target dangerousness of the previous trial and that of the current trial. In current Go trials, the behavioral results revealed a classical motor interference effect in trials that were preceded by a safe trial (a longer reaction time (RT) and a larger error rate for the previous safe and current dangerous (sD) condition than for the previous safe and current safe (sS) condition). However, the motor interference effect diminished in trials that were preceded by a dangerous trial (insignificant differences in the mean RTs and error rates between the previous dangerous and current dangerous (dD) condition and the previous dangerous and current safe (dS) condition). The event‐related potential (ERP) results identified more positive P2 and parietal P3 amplitudes (indicating attentional resource allocation) for the dD condition than for the dS condition. However, the P2 and parietal P3 amplitudes of the sD condition did not significantly differ from those of the sS condition. These results support the hypothesis that the avoidance motivation elicited by a dangerous target in a previous trial may indicate a dangerous situation, which leads to recruitment of more attentional resources allocated to the subsequent dangerous trial. Therefore, RTs are improved and errors are reduced in the consecutive dangerous condition, subsequently decreasing the motor interference effect in trials preceded by a dangerous trial compared with trials preceded by a safe trial. However, analysis of current NoGo trials revealed that none of the main effects or interactions reached significance in both the behavioral and ERP results, indicating that the hypothesis holds true only if the prepared response needs to be executed.
