Young, Sutherland, and McCoy indicated that a Go/No‐Go Task (GNG) becomes more difficult as the inter‐stimulus intervals (ISIs) becomes shorter. However, is the number of commission errors under extremely short ISIs a useful metric for assessing response inhibition? This study challenges the assumption that a shorter ISI in the GNG enables better assessment of response inhibition. University students (N = 213) completed the GNG, the Conners Continuous Performance Test 3rd Edition (CCPT), and the Modified Stroop Task. The GNG comprised four blocks of 400, 600, 800, and 1000 ms ISIs, whereas the stimulus presentation was fixed at 250 ms. Consistent with Young et al., shorter ISIs in the GNG resulted in more commission errors. In the block with the shortest ISI, participants also failed more frequently in responses in go trials than in the other blocks, which appears to increase in error variance of commission errors. Consistent with this interpretation, the association between the number of commission errors in the block with 400 ms ISI and CCPT performance was weaker than those between the number of commission errors in other blocks and CCPT performance. It is concluded that using the number of commission errors in the condition with extremely short ISIs in the GNG might be inappropriate for assessing response inhibition.

在执行/不执行任务中较短的刺激间隔时间是否可以更好地评估反应抑制？

Young，Sutherland和McCoy表示，随着刺激间隔（ISI）的缩短，执行/不执行任务（GNG）变得更加困难。但是，极短的ISI下的佣金错误数量是否是评估响应抑制的有用指标？这项研究挑战了以下假设：GNG中较短的ISI可以更好地评估反应抑制。大学生（N = 213）完成了GNG，Conners持续表现测试第三版（CCPT）和修改后的Stroop任务。GNG包括四个块，分别是400、600、800和1000毫秒的ISI，而刺激表示则固定为250毫秒。与Young等人一致.. GNG中较短的ISI导致更多的佣金错误。在ISI最短的区块中，参加者在围棋审判中的响应失败率也比其他区块更高，这似乎增加了佣金错误的误差方差。与该解释一致，具有400 ms ISI的块中的调试错误数与CCPT性能之间的关联性弱于其他块中的调试错误数与CCPT性能之间的关联性。结论是，在GNG中ISI极短的情况下使用佣金错误的数量可能不适用于评估响应抑制。
