厭惡情緒詞匯的加工及神經(jīng)機(jī)制研究
[Abstract]:Different theories have different views on the processing of emotional vocabulary. According to the traditional theory, the emotional response to vocabulary comes from reading itself, which is the activation of abstract semantics. That is to say, when we read, we must first understand the meaning of words, and then produce corresponding emotions. In contrast, the emerging theory of neural reuse suggests that the brain region is involved in processing emotional information about various stimuli (faces, pictures, smells), as well as processing the emotional information of words. In other words, brain regions are directly involved in processing emotional information. The point of view of neural reuse assumes that recently acquired cognitive functions (such as language) are not new network products, but originated from the recombination of "ancient" components, which also participate in other cognitive functions. According to this view, emotional vocabulary activates areas of the brain outside the classic reading network (such as the amygdala, the islands, and the prefrontal cortex), and the regions that process emotions are not areas of reading. So when the emotional vocabulary is processed needs to be further explored. A particular emotion-disgust. Select Chinese words that can arouse people's aversion. If we use the forebrain island as a possible location for the brain to process aversion, then the neural reuse theory will predict that the vocabulary of aversion content will quickly activate this structure. Conventional theory may not predict activation of forebrain islands, but may predict activation of classic reading networks. In order to verify the theory of emotional vocabulary processing, we conducted a series of experimental studies. The first is behavioral experiment, which allows people to look at Chinese words and quickly decide whether they are disgust or neutral. If disgust words, the right index finger by the left mouse button response; if neutral words, right-handed reaction. The responses to neutral and disgust words were recorded. If the reaction time of disgust words was less than that of neutral words, emotional processing was earlier than other processing. The second is EEG experiment, which requires Chinese words to be tried and whether the words presented are vehicles or not. If it is the right index finger of the vehicle press the keyboard "Y" key response, if not do not react. This puts aversion and neutral words at the same level of inhibition processing, recording brain waves and behavioral data. If the response to disgust was earlier than 400 msand significantly different from that of neutral words, it could be indirectly proved that the emotional processing of vocabulary was earlier than the processing of meaning. The results were as follows: (1) the emotional information carried by vocabulary itself significantly affected our judgment of vocabulary. (2) the processing of disgust words was faster than that of neutral words. That is, the processing of emotional vocabulary is superior to that of neutral vocabulary. (3) emotional reaction to emotional vocabulary is earlier than processing of its meaning. (4) processing of emotional vocabulary, It follows the theory of neural reusability. (5) the time required for the activation of the cortex in Chinese is shorter than that of the cortex in French.
