本文报告了在停止信号范式中操纵的选择反应和选择性停止过程的加性因素分析。在三个实验中，刺激可辨别性（SD）和刺激-反应相容性（SRC）以因子的方式被操纵。在每个实验中，先评估SD和SRC的作用，然后再评估停止作用。两个实验得出了预期的SD和SRC之间的加性关系，但停止似乎对SD操作不敏感。在第三个实验中，通过使用不同的显示来增加SD需求，导致SD和SRC之间在行进时产生显著的（过度加性）相互作用，而在停止时产生不显著的（欠加性）相互作用。从这组实验中出现的结果模式被解释为表明前进和停止既相似又不同。它们的相似之处在于，在前进和停止中可以识别出不同的阶段，但它们也不同，因为相对于前进，选择性停止似乎对歧视操纵不那么敏感。(C) 2004爱思唯尔公司版权所有。
This article reports an additive factors analysis of choice reaction and selective stop processes manipulated in a stop-signal paradigm. Three experiments were performed in which stimulus discriminability (SD) and stimulus-response compatibility (SRC) were manipulated in a factorial fashion. In each experiment, the effects of SD and SRC were assessed first for going and next for stopping. Two experiments yielded the anticipated additive relation between SD and SRC for going but stopping appeared to be insensitive to the SD manipulation. Increasing the SD demands in the third experiment by using a different display resulted in a significant (over-additive) interaction between SD and SRC for going and a non-significant (under-additive) interaction for stopping. The pattern of results that emerged from this set of experiments was interpreted to suggest that going and stopping are both similar and different. They are similar in that distinct stages can be identified in both going and stopping but they are also different, as selective stopping seems to be less sensitive to discrimination manipulations relative to going.
