【摘要】：在人们的日常口语交流中,无论言语者的语速、年龄、性别等因素怎样变化,人们都可以毫不费力的理解交谈中的口语词汇,这个看似简单的过程其实经历了一系列复杂的认知加工。本研究采用高时间分辨率的事件相关电位(ERP)技术考察了情绪韵律这一副语言线索和竞争环境对口语词汇识别的时间进程的影响。本研究包括两个实验,均采用匹配范式,被试的任务都是判断目标词和启动词是否匹配,实验一使用高兴和愤怒情绪表达的语义中性双音节词,考察情绪韵律对口语词汇识别进程的影响,实验二使用中性情绪表达的语义中性双音节词,通过两部分实验创造不同的竞争环境,考察竞争环境对口语词汇识别的影响。实验一分为两个部分,首先在启动情绪和目标情绪一致条件下考察韵律(高兴、愤怒)和语义(相同、完全不同)的关系,其次,在启动词和目标词一致的条件下考察情绪(一致,不一致)和韵律(高兴、愤怒)的关系。实验二也包含两个部分,第一部分是低语音竞争环境,有两个条件：语义(完全相同、完全不同),第二部分是高语音竞争环境,有三个条件：语义(完全相同、完全不同、词首相同)。在行为结果上：实验一,启动情绪和目标情绪一致条件下语义不同比语义相同反应更快,启动词和目标词一致条件下愤怒情绪比高兴情绪反应更快,说明启动情绪相同时,语义相同能使判断易化,而启动词和目标词一致时,人们对情绪的反应出现了负性偏向。实验二,第一部分显示语义相同比语义不同反应更快,正确率更高；第二部分,词首相同反应最慢,其次是完全相同,完全不同反应最快,说明对词首相同的条件加工难度最大。在ERP结果上,实验一显示在启动情绪和目标情绪一致条件下,语义不同比语义相同引发更正的P2成分和更负的N400成分；在启动词和目标词一致下,愤怒比高兴引发更正的P2成分。实验二第一部分显示,语义不同比语义相同有更正的P2和更负N400；第二部分显示,完全不同条件引发的的P2最正,词首相同条件诱发的N400最正。因此,情绪韵律并不影响口语词的加工,竞争环境在口语词汇的语义加工阶段影响口语词汇的识别。
[Abstract]:In people's daily oral communication, no matter how the speaker's speed, age, gender and other factors change, people can easily understand the spoken words in the conversation. This seemingly simple process actually goes through a series of complex cognitive processes. In this study, the influence of emotional prosody, a linguistic clue and competitive environment, on the time course of oral vocabulary recognition was investigated by means of high temporal resolution event-related potential (ERP) technique. This study consists of two experiments, both of which adopt matching paradigm. The task of the subjects is to determine whether the target word and the primer word match. Experiment 1 uses the semantic neutral disyllabic words expressed by happy and angry emotions. To investigate the influence of emotional prosody on the process of oral vocabulary recognition, experiment two uses semantic neutral dicyllabic words expressed by neutral emotion to create different competitive environment and examine the influence of competitive environment on oral vocabulary recognition. Experiment one is divided into two parts. First, we examine the relationship between prosody (pleasure, anger) and semantics (identical, completely different) under the condition of consistent priming emotion and target emotion, and secondly, The relationship between emotion (consistency, inconsistency) and prosody (pleasure, anger) is examined under the condition of consistency between the initiator and the target word. Experiment two also contains two parts. The first part is low speech competition environment, and there are two conditions: semantic (identical, completely different, the second part is high voice competition environment), there are three conditions: semantics (identical, completely different). The beginning of the word is the same. In behavioral results: experiment 1, semantic difference is faster than semantic same reaction under the condition of consistent priming emotion and target emotion, anger reaction is faster than happy emotion reaction under the condition of consistent priming word and target word, indicating that when the priming emotion is the same, Semantic similarity can make judgment easier, but when primer and target word are consistent, people's reaction to emotion appears negative bias. In experiment two, the first part shows that semantic homogeneity is faster and the correct rate is higher than that of different semantic reactions; in the second part, the first part of the word has the slowest reaction, the second part is completely identical, and the completely different reaction is the fastest. It shows that the processing of the same conditions at the beginning of the word is the most difficult. In terms of ERP results, experiment 1 shows that under the condition of consistent priming emotion and target emotion, the semantic difference leads to correction of P2 component and more negative N400 component than semantic identity, and under the condition of consistent priming word and target word, the semantic difference leads to correction of P2 component and more negative N400 component. Anger is more than happy to trigger correction of the P2 component. The first part of the experiment shows that the semantic difference is the same as the same semantic P2 and the negative N400, and the second part shows that the P2 caused by completely different conditions is the most positive, and the N400 induced by the same condition at the beginning of the word is the most positive. Therefore, emotional prosody does not affect the processing of spoken words, and competitive environment affects the recognition of spoken words in the semantic processing stage.
