言语自我监控中的填充暂停研究

填充暂停,作为一种间断语流现象,是自然言语的有机组成部分。笔者结合汉语口语的真实语料,探究汉语口语中填充暂停现象的特点。研究发现:填充暂停的分布特征受认知任务复杂性影响;作为说话人的一种认知策略,填充暂停具有指示修正,重新计划言语和保留话轮的认知功用,体现了说话人运用元认知进行言语自我监控的能力。上述发现对揭示言语生成机制的真实面目具有启示意义。

发展性口吃的脑机制

口吃是一种常见的言语障碍,对此曾提出过大脑半球言语功能偏侧化异常假设。近期,发展性口吃的神经成像研究在支持这一经典假设的同时,还发现负责言语监控的颞叶系统和负责言语运动控制的额叶系统与皮层下脑结构存在功能失调,这可能损害言语产生时的精确时间控制。据此,研究者开始用神经网络的观点来解释发展性口吃产生的脑机制,认为患者可能存在由多个言语产生相关脑区构成的“双通路”网络的功能障碍。

Study on the Practice Teaching Quality Guarantee and Monitoring System of English Program in Local Colleges and Universities

In today＇ s society, there are increasingly more new requirements on English education in local colleges and universities, and also there are some problems to be exposed.
