研究表明，与不规则节奏启动词相比，规则节奏启动词能提高对随后呈现句子的语法性判断。在动态参与的理论框架中，有规律的节奏启动被认为是驱动神经振荡的节奏。一旦启动完成，这些振荡就会持续下去，产生一种促进后续句子处理的全局增强激活状态。到目前为止，这种全球节奏启动效应主要表现在大约30秒或更长时间的启动上。为了探讨较短的启动词是否也有助于语法判断，我们对两组7 - 9岁的儿童（Ms = 8.67和8.58岁）进行了两个实验。实验1的启动持续时间为8秒和16秒，实验2的启动持续时间为16秒和32秒。在实验2中，32-s的启动同样具有节律性。实验1中8-s、16-s及实验2中32-s启动后的阅读年龄与表现水平均呈显著正相关。此外，实验2中32-s组的正常启动效应随实足年龄的增长而增加。研究结果表明，当测试当前年龄范围的儿童时，（至少）32-s启动在全球节奏启动研究中是最佳的，并且结果可能受到实足年龄和阅读年龄的调节。结果讨论了动态参与理论、神经振荡强度、发展考虑以及节奏刺激在语言康复中的意义。(C) 2020爱思唯尔公司版权所有。
Research has shown that regular rhythmic primes improve grammaticality judgments of subsequently presented sentences compared with irregular rhythmic primes. In the theoretical framework of dynamic attending, regular rhythmic primes are suggested to act as driving rhythms to entrain neural oscillations. These entrained oscillations then sustain once the prime has finished, engendering a state of global enhanced activation that facilitates the processing of subsequent sentences. Up to now, this global rhythmic priming effect has largely been shown with primes that are approximately 30 s or more. To investigate whether shorter primes also facilitate grammaticality judgments, two experiments were run on two groups of children aged 7 to 9 years (Ms = 8.67 and 8.58 years, respectively). Prime durations were 8 and 16 s in Experiment 1, and they were 16 and 32 s in Experiment 2. Rhythmic priming was observed in Experiment 2 for 32-s primes, as observed previously. Furthermore, positive correlations were found between reading age and performance level after regular primes for both 8-s and 16-s primes in Experiment 1 and for 32-s primes in Experiment 2. In addition, the benefit of the regular primes increased with chronological age for the 32-s primes in Experiment 2. The findings suggest that (at least) 32-s primes are optimal in global rhythmic priming studies when testing children in the current age range and that results may be modulated by chronological age and reading age. Results are discussed in relation to dynamic attending theory, neural oscillation strength, developmental considerations, and implications for rhythmic stimulation in language rehabilitation.
