本文考察了发音抑制对数字-大小一致性任务的影响，以考察语音环路在任务无关刺激属性潜在干扰的情况下的参与情况。参与者被展示了数字和物理大小不同的数字对，他们被要求在数字大小和物理大小判断任务中分别判断哪个数字在数字上或物理上更大。连续任务组的参与者只完成数字大小判断任务。另一方面，改变任务组的参与者先练习实体大小判断任务，然后执行数字大小判断任务。结果表明，发音抑制对数字大小判断任务中的反应时有负向影响，仅在改变任务组中存在。这表明，当参与者在维持任务目标的困难情况下面临干扰时，语音环路为控制行动提供了有用的帮助。
This paper considers the effect of articulatory suppression on a number-size consistency task to investigate the involvement of the phonological loop in situations involving potential interferences from task-irrelevant stimulus attributes. Participants were shown pairs of digits varying in numerical and physical sizes, and they were required to decide which digit was larger numerically or physically in the numerical-size and physical-size judgment tasks, respectively. Participants in the continuous-task group only performed the numerical-size judgment task. On the other hand, participants in the change-task group practiced the physical-size judgment task and then performed the numerical-size judgment task. The results showed that articulatory suppression had a negative effect on reaction time in the numerical-size judgment task only in the change-task group. This suggests that the phonological loop provides a useful aid for the control of action when participants are faced with interference in a difficult situation of maintaining the task goal.
