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.
扬、萨瑟兰和麦科伊指出，随着刺激间隔时间（ISI）缩短，强制选择任务（GNG）会变得更加困难。然而，在极短ISI情况下的错误反应数量是否是评估反应抑制的有用指标呢？本研究对GNG中较短ISI能更好地评估反应抑制这一假设提出了质疑。大学生（N = 213）完成了GNG、康纳斯连续操作测验第三版（CCPT）和改良斯特鲁普任务。GNG包括四个块，ISI分别为400、600、800和1000毫秒，而刺激呈现时间固定为250毫秒。与扬等人的研究一致，GNG中较短的ISI导致更多的错误反应。在ISI最短的块中，参与者在“执行”试验中的反应失败频率也比其他块更高，这似乎增加了错误反应的误差方差。与此解释一致，400毫秒ISI块中的错误反应数量与CCPT表现之间的关联比其他块中的错误反应数量与CCPT表现之间的关联更弱。研究得出结论，在GNG中使用极短ISI条件下的错误反应数量来评估反应抑制可能并不合适。
