Abstract

Numerous behavioral studies have demonstrated a rhythmic priming effect (RPE) on grammatical processing using grammaticality judgment tasks (GJT), where participants performed better following regular rhythmic sequences compared to baseline conditions or irregular rhythmic sequences (i.e. auditory rhythmic sequences with violated metrical structure). Only a few studies, however, have explored neurophysiological RPE in grammatical processing. Such neurophysiological investigations have been limited to GJT presented auditorily, have been primarily focused on the French- and German-speaking adult participants, and have rarely used baseline nonpriming conditions. The objective of the present study was to investigate neurophysiological correlates of the RPE in the GJT presented in visual modality. In the current study, we registered a 128-channel electroencephalogram while Russian-speaking adolescents performed a visual GJT, where each sentence was presented word by word in a self-paced manner. Before each experimental block, participants listened to regular rhythmic sequences, irregular rhythmic sequences, or silence. We observed that the late negativity in the event-related potential was larger for the ungrammatical condition compared to the grammatical condition only after the presentation of irregular rhythmic sequences. This effect, referred to as the N600 component in previous research, has been associated with increased cognitive complexity. In conclusion, results suggest that exposure to irregular rhythmic stimulation may lead to increased cognitive demand. This is attributed to the complexity associated with concurrently executing the GJT and managing rhythmic disruption, consequently increasing the strain on working memory resources.

音乐节奏如何在神经生理学层面影响语法加工?
许多行为学研究通过语法性判断任务(GJT)证明了节奏引物效应(RPE)对语法加工的影响,与基线条件或不规则节奏序列(即违反韵律结构的听觉节奏序列)相比,参与者在有规律的节奏序列中表现得更好。然而,只有少数研究探讨了语法加工中的神经生理学 RPE。这些神经生理学研究仅限于听觉呈现的 GJT,主要集中在讲法语和德语的成人参与者身上,而且很少使用基线非触发条件。本研究的目的是调查以视觉模式呈现的 GJT 中 RPE 的神经生理学相关性。在本研究中,我们在讲俄语的青少年进行视觉 GJT 时记录了 128 个通道的脑电图。在每个实验块之前,受试者先听有规律的节奏序列、无规律的节奏序列或沉默。我们观察到,与语法条件相比,只有在呈现不规则节奏序列后,非语法条件下事件相关电位的后期负性才会更大。这种效应在以往的研究中被称为 N600 分量,与认知复杂性的增加有关。总之,研究结果表明,接触不规则节奏刺激可能会导致认知需求增加。这归因于同时执行 GJT 和管理节奏干扰的复杂性,从而增加了对工作记忆资源的压力。

期刊介绍: NeuroReport is a channel for rapid communication of new findings in neuroscience. It is a forum for the publication of short but complete reports of important studies that require very fast publication. Papers are accepted on the basis of the novelty of their finding, on their significance for neuroscience and on a clear need for rapid publication. Preliminary communications are not suitable for the Journal. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool. The core interest of the Journal is on studies that cast light on how the brain (and the whole of the nervous system) works. We aim to give authors a decision on their submission within 2-5 weeks, and all accepted articles appear in the next issue to press.
