摘 要： 

　　Catecholamine (CA) neurotransmitters (e.g., dopamine) have long been implicated playing a critical role in executive control and decision making. Recently, evidence from neurodegenerative patients and healthy population suggested that CA also modulates language processing. However, the question of what kind of influence the CA might exert on language is still open. My recent study investigated this question by examining the effects of methylphenidate (MPH), which is a CA agonist, on EEG response related to language processing. The results demonstrated a clear neuropharmacological effect that CA neurotransmitters provide a relevance signal that enhances semantic integration operations, regardless of whether language processing is goal-relevant or not. The Basal Ganglia projections to Frontal Cortex might mediate the language processing effects of these neuropharmacological agents. These results contradicted the general hypothesis that CA promotes goal-relevant processes, while inhibiting goal-irrelevant information, suggesting that our capacity for language is a core system rooted in our biological system. 

报告者简介： 

　　谭滢滢博士2008年本科毕业于北京大学心理学系，2015年获得美国Rice University心理学系认知神经科学博士学位，现在荷兰马克思普朗克研究所心理语言学中心从事博士后研究。主要研究方向是人类语言加工的认知神经基础，比如语言加工与工作记忆和认知控制功能的交互影响，以及特定神经药物干预对语言加工的影响。主要研究方法包括结合EEG技术和使用心理药理学手段，测量个体认知行为能力差异，考察健康被试和脑损伤病人（失语症患者）的语义语法系统加工，与认知障碍的认知基础。
