Abstract

Socio-pragmatic factors, such as social roles and language experience, could be key variables influencing language processing. However, little is known regarding the neural correlates of syntactic processing mediated by socio-pragmatic factors. Honorific agreement in Japanese is well-suited for the investigation of this issue. Japanese honorifics are governed by socio-pragmatic and syntactic rules. Lower social status speakers are expected to address higher social status counterparts in accordance with these rules. This linguistic skill is typically developed through language experience accrued in social contexts. The present functional magnetic resonance imaging study investigated the neural correlates of the honorific agreement processing mediated by socio-pragmatic factors. Thirty-three native Japanese speakers performed a socio-pragmatic judgment task containing sentence conditions manipulated by conventionality (i.e., conventional vs. unconventional) and speaker (lower-status vs. higher-status). The lower-status conditions elicited significantly more activation of the left inferior frontal gyrus (IFG), bilateral insula, and dorsal medial prefrontal cortex than the higher-status ones, irrespective of conventionality. This suggests that social cues (i.e., speaker social status) trigger computation of honorific agreement via the left IFG. Furthermore, the conventional conditions significantly enhanced activation of the bilateral anterior temporal lobes (ATLs), compared with the unconventional conditions. Finally, the listener's experience with honorific use in the workplace was positively correlated with activation of the left inferior parietal lobule (IPL) during comprehension of conventional honorific utterances. Our findings demonstrate the importance of socio-pragmatic factors in Japanese honorific agreement processing, which involves the ATLs and IPL.

社会语用因素介导的日语敬语协议加工的神经关联:fMRI研究
社会语用因素,如社会角色和语言经验,可能是影响语言加工的关键变量。然而,关于社会语用因素介导的句法加工的神经关联,人们知之甚少。日语中的敬语约定非常适合研究这一问题。日语的敬语受社会语用规则和句法规则的支配。社会地位较低的说话者应该按照这些规则来称呼社会地位较高的说话者。这种语言技能通常是通过在社会环境中积累的语言经验而发展起来的。功能磁共振成像研究了社会语用因素介导的敬语协议加工的相关神经机制。33名以日语为母语的人执行了一项社会语用判断任务,该任务包含由传统(即传统与非常规)和说话者(低地位与高地位)操纵的句子条件。地位较低的情况下,与地位较高的情况相比,左侧额下回(IFG)、双侧脑岛和前额叶背内侧皮层的激活明显更多,与传统无关。这表明社会线索(即说话人的社会地位)通过左侧IFG触发了敬语协议的计算。此外,与非常规条件相比,常规条件显著增强了双侧颞叶(ATLs)的激活。最后,听者在工作场所使用敬语的经历与理解传统敬语时左顶叶下叶(IPL)的激活呈正相关。我们的研究结果表明,社会语用因素在日语敬语协议处理中的重要性,这涉及到atl和IPL。

期刊介绍: The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
