Chinese Sentences Emotional Prosody And Semantics Expected Violation Processing Research

In our daily life, a correct understanding of spoken language in semantic and prosodic information for human daily communication is very important. Generally speaking, in language communication, as the content, the listener will form expectations to the speaker of semantic expression and emotion. The listener must quickly detect discourse semantic information and changes in emotional prosodic changes, and new content of the semantic and prosodic information into context, to generate accurate language understanding. This research used the ERP technology, study in Chinese sentences, if there is violation of semantic expectations or prosodic expectancy violation, how to influence the cognitive processing.This paper uses the sentence level of experimental materials, please professional announcer respectively by neutral, happy and angry after reading, using cross-splicing technology on the experimental material stitching, to generate the semantic expectancy violation, expectancy violationof emotional prosody and two expectancy violation. Through a semantic judgment task and emotional prosody judgment task, study semantic processing and emotional prosodic processing, the emotional valence and the relationship between the two.Behavioral results showed:(1) From the reaction time can be seen, prosody task response time significantly faster than semantic task response time. Therefore, the semantic processing and emotional prosody processing at different stages of processing, semantic processing is an advanced stage of processing, and emotional prosody processing belongs to the lower stage of the early processing.(2) The semantic task, when prosodic expectancy violation in anger, reaction time is far less than the other. Indicate that prosodic expectancy violation in anger, will easily people on the semantic content of the judgment.(3) The prosodic task, semantic expectations on prosodic judgments do not have significant impact.(4) Two experimental tasks, there are negative emotional bias. When the emotional prosody in anger, reaction time most quickly. In conclusion, emotional valence in a certain extent influence the processing.ERP results showed:(1)Emotional prosody processing starts earlier, approximately from the segmentation point100ms began, and semantic processing occurred some segmentation point550ms.(2) The semantic task, when emotional prosodic expectancy violation, the semantic expectancy violation judgment can have stimulative effect, the left hemisphere has obvious superiority for processing(3) Emotional prosody task, when semantic expected violation, the emotional prosodic expectancy violation judgment would also be affected, changed the emotional valence on the ERP composition influences the trend, the whole process of the apparent absence of cerebral hemispheric dominance effectIn conclusion, emotional prosodic and semantic processing belong to different processing stages, when emotional prosodic expectancy violation, the semantic expectancy violation judgment can have stimulative effect, and when the expected semantic violation, the emotional prosodic expectancy violation judgment would also be affected, changed the emotional valence on ERP components influence trend. These effects were observed in emotional prosodic expectancy violation of negative emotion of anger. So emotional prosodic and semantic processing are both independent also have interaction.
