本研究采用一种常用的研究范式，即交替运行范式，考察了语音回路在任务转换绩效中的作用。这种模式基本上要求参与者在每第二次试验中交替任务（即，AABBAABB）。在这项研究中，被试被要求在控制、发音抑制和足部敲击条件下，在线索存在和线索不存在的条件下交替完成字母和数字决策任务。结果表明，在两种提示条件下，无论是转换还是非转换，发音抑制条件下的错误率都大于控制条件和敲击条件下的错误率，反应时也长于控制条件和敲击条件下的反应时。这些研究结果表明，语音回路有助于任务绩效不仅在切换试验，但也在需要维护的任务序列信息的情况下。
We examined the role of the phonological loop in task switching performance in a prevalently used research paradigm, that is, the alternating runs paradigm. This paradigm basically requires participants to alternate tasks on every second trial (i.e., AABBAABB). In this study, participants were required to alternate the letter and numerical decision tasks in cue-present and cue-absent conditions under control, articulatory suppression and foot tapping conditions. The results showed that error rates were larger and reaction times were longer in the articulatory suppression condition than in the control and tapping conditions for both switch and nonswitch trials in two cue conditions. These findings indicate that the phonological loop contributes to task performance not only in the switching trials but also in situations where the maintenance of task sequence information is required.
