【摘要】：情緒與工作記憶的關(guān)系是情緒與認知研究領(lǐng)域中一個重要的分支。以往有關(guān)情 緒對工作記憶影響的研究有兩個不同的取向。一個方向是根據(jù)工作記憶材料類型— 言語信息、空間信息和客體信息—的不同,情緒對工作記憶的影響不同。這方面的 研究發(fā)現(xiàn)情緒對工作記憶產(chǎn)生了選擇性影響。即消極情緒選擇性影響了空間工作記 憶,而不影響言語工作記憶；積極情緒選擇性影響了言語工作記憶,而不影響空間 工作記憶。另一個方向是根據(jù)工作記憶任務(wù)要求的加工—保持加工和操作加工—不 同,情緒也會對工作記憶產(chǎn)生不同的影響。這方面的研究發(fā)現(xiàn)無論是積極情緒還是 消極情緒都僅對操作加工產(chǎn)生影響,而對保持加工無影響。因而研究者認為情緒對 工作記憶的影響是通過情緒對不同加工的影響實現(xiàn)的。目前第二個方向的研究剛剛 涉及,相關(guān)研究較少,特別是ERP的研究較少。本研究在現(xiàn)有第二個方向研究的基 礎(chǔ)上,運用ERP技術(shù)探討情緒對工作記憶影響的腦機制。本研究以正常大學(xué)生為被試,采用ERP技術(shù),以中國影像庫中快樂和中性視頻 為情緒誘發(fā)材料,采用修改的延遲樣本匹配任務(wù)——字母數(shù)字任務(wù),分離了保持過 程和操作過程。進而考察了積極情緒對工作記憶保持和操作的選擇性影響。研究結(jié) 果表明：積極情緒促進工作記憶操作過程,對保持過程無影響。具體結(jié)果表現(xiàn)在：(1)在行為績效上,積極情緒對工作記憶操作過程的促進作用表現(xiàn)在：與中 性條件相比,積極情緒下操作任務(wù)的正確率顯著提高。(2)在ERP水平上,積極情緒對工作記憶操作過程的促進作用體現(xiàn)在：積極 情緒下,相比于中性條件,操作任務(wù)在延遲階段的P2波幅,P3波幅,lateLPP波幅 走向更正,N300波幅走向更負。這說明積極情緒從早期注意資源的分配,詞意理 解到后期注意的分配和注意保持等都產(chǎn)生影響。在積極條件和中性條件下的保持任 務(wù)則無差異�？偠灾�,本研究結(jié)果表明積極情緒促進了工作記憶的操作。同時對工作記憶 保持無影響。該結(jié)果表明,積極情緒可能通過影響工作記憶的操作進而影響工作記 憶的。
[Abstract]:The relationship between emotion and working memory is an important branch in the field of emotion and cognition. Past situation There are two different orientations in the study of the effect of thread on working memory. One direction is based on the type of working memory material The influence of emotion on working memory is different between speech information, spatial information and object information. In this respect The study found that emotion had a selective effect on working memory. That is, negative emotion selectivity affects the spatial work record. Memory, but not speech working memory; positive emotion selectivity affects speech working memory, but not space Working memory. Another direction is processing according to the working memory task-maintaining processing and operating processing-no Similarly, emotions can also have different effects on working memory. Research in this area has found that both positive emotions and Negative emotions only affect the operation process, but have no effect on the maintenance processing. So the researchers think that emotion is right. The effect of working memory is realized through the effect of emotion on different processing. So far, the second direction of research has just been Involved, the correlation research is relatively few, especially the ERP research is less. The basis of the present study in the second direction To explore the brain mechanism of emotional effects on working memory by using ERP technique. In this study, normal college students were chosen as subjects, and ERP technology was used to study the happy and neutral video in Chinese image library. For emotion-inducing material, the modified delayed sample matching task-alphanumeric task was used to separate the retention Process and operation process. Furthermore, the selective effects of positive emotions on working memory retention and manipulation were investigated. Research knot The results showed that positive emotion promoted the operation of working memory, but had no effect on the maintenance process. The specific results are as follows: (1) in terms of behavior performance, the positive emotion promotes the working memory operation process as follows: Compared with the sexual condition, the correct rate of the operation task under the positive emotion is significantly increased. (2) at the level of ERP, the positive emotion can promote the working memory operation process as follows: positive In mood, compared with neutral conditions, the P2 and P3 amplitudes of the operation task at the delayed stage are equal to the lateLPP amplitudes. The trend correction of N300 amplitude is more negative. This shows that positive emotions from the early attention to the allocation of resources, meaning. The distribution of attention and the retention of attention have an effect on the late stage. Retention under positive and neutral conditions There is no difference in service. All in all, the results of this study suggest that positive emotions facilitate the manipulation of working memory. Simultaneous working memory Remain unaffected. The results suggest that positive emotions may affect work memorization by affecting the operation of working memory. Recall.
