患有发育性语言障碍的儿童在节奏和节拍感知方面也被证明受损。时间处理及其与语言处理的联系可以在动态注意理论中理解。外部刺激可以刺激内部振荡器，其随着时间的推移定向注意力并驱动语音信号分割以提供语法处理的益处，这在各种患者群体中受损。对于有特殊语言障碍（SLI）和阅读障碍的儿童，先前的研究通过比较时间上规则的音乐启动和时间上不规则的启动的影响来显示外部节奏刺激对随后的语言处理的影响。在这里，我们测试了所观察到的节奏刺激效果是否确实是由于规则的音乐启动所提供的益处（而不是时间上不规则的启动之后的成本）。16名SLI儿童和16名年龄匹配的对照组儿童听常规音乐启动序列或环境声音场景（事件发生时没有时间间隔;即，称为“基线条件”），然后是语法正确和不正确的句子。他们被要求对每一个错误陈述的句子进行语法判断。结果表明，规则的素数序列后的语法判断性能比基线序列后更好。我们的研究结果被解释在动态注意理论的理论框架（琼斯，）和时间采样（振荡）的发展性语言障碍的框架（Goswami，）。此外，他们鼓励使用节奏结构（即使在非语言材料），以促进语言结构处理和概述康复的前景。
Children with developmental language disorders have been shown to be also impaired in rhythm and meter perception. Temporal processing and its link to language processing can be understood within the dynamic attending theory. An external stimulus can stimulate internal oscillators, which orient attention over time and drive speech signal segmentation to provide benefits for syntax processing, which is impaired in various patient populations. For children with Specific Language Impairment (SLI) and dyslexia, previous research has shown the influence of an external rhythmic stimulation on subsequent language processing by comparing the influence of a temporally regular musical prime to that of a temporally irregular prime. Here we tested whether the observed rhythmic stimulation effect is indeed due to a benefit provided by the regular musical prime (rather than a cost subsequent to the temporally irregular prime). Sixteen children with SLI and 16 age-matched controls listened to either a regular musical prime sequence or an environmental sound scene (without temporal regularities in event occurrence; i.e., referred to as “baseline condition”) followed by grammatically correct and incorrect sentences. They were required to perform grammaticality judgments for each auditorily presented sentence. Results revealed that performance for the grammaticality judgments was better after the regular prime sequences than after the baseline sequences. Our findings are interpreted in the theoretical framework of the dynamic attending theory (Jones,) and the temporal sampling (oscillatory) framework for developmental language disorders (Goswami,). Furthermore, they encourage the use of rhythmic structures (even in non-verbal materials) to boost linguistic structure processing and outline perspectives for rehabilitation.
