It is hypothesized that pauses at major syntactic boundaries (i.e., grammatical pauses), but not ungrammatical (e.g., word search) pauses, are planned by a high-level cognitive mechanism that also controls the rate of articulation around these junctures. Real-time magnetic resonance imaging is used to analyze articulation at and around grammatical and ungrammatical pauses in spontaneous speech. Measures quantifying the speed of articulators were developed and applied during these pauses as well as during their immediate neighborhoods. Grammatical pauses were found to have an appreciable drop in speed at the pause itself as compared to ungrammatical pauses, which is consistent with our hypothesis that grammatical pauses are indeed choreographed by a central cognitive planner.
人们假设，在主要句法边界（即语法停顿）处的停顿是由一个高级认知机制计划的，而不是在不合法的（例如，寻找单词）停顿处计划的，该机制还控制了在这些连接处的发音速度。实时磁共振成像是用于分析自发言语中语法停顿和非语法停顿处的发音。在这些停顿以及它们的直接邻近处，开发并应用了定量测量发音器官速度的措施。与不合法的停顿相比，语法停顿在停顿本身处的速度明显下降，这与我们的假设一致，即语法停顿确实是由中央认知计划者精心编排的。
