摘要：With the development of Affective Neuroscience, people are increasingly concerned about the relationship between emotion and cognition. Language, as a means of communicating and studying in human society, is one of the vital cognitive activities of human beings. Therefore, the relationship between emotion and language processing is valued by researchers all over the world. According to the Interaction Theory, this paper uses observational method to observe the listeners’ reactions to Ivanka’s speech, including the applause, the yell, face expression, and action, to study the influence of emotion on language processing and language learning so as to study children language teaching methods which can motivate students’ interests in learning and improve their language learning efficiency by applying the methods of public speech to the academic speech. The study about Ivanka’s speech is mainly from two aspects:(1) the influence of emotional information in language on language learning, including emotional words, sentences, and speeches;(2) the influence of external emotional background on language learning, including the emotional intonation, speech rhythm, and context. What’s more, the author spends one year in studying the effect of applying the public speech methods on children language learning. The author finds that applying the speech methods of public speech to academic speech has vital influence on motivating children’s learning interests and improving their learning efficiency.
