学生的首因效应对教师情绪感染力的影响：情绪真实性判断的中介作用

首因效应可能通过对他人情绪真实性判断的影响间接作用于情绪感染的效果。研究采用两因素混合设计。首先向两组被试散布有关教师的“正面信息”或“负面信息”，然后通过观看该教师的朗诵视频来测量教师的情绪感染力以及教师的情绪真实性。所不同的是在实验组与对照组中使用了不同的信息散布方式，实验组采用情境引导，对照组采用抽签引导。研究结果表明，实验组成功建立了关于教师的第一印象，并对情绪真实性判断和情绪感染产生影响，出现首因效应。而对照组未成功建立第一印象，因此没有出现情绪感染的首因效应。路径分析表明，首因效应通过情绪真实性判断对情绪感染产生完全中介效应。

The Regulation Effect of Students' Primacy Effect on Teacher's Emotional Contagion: The Mediating Effects of Authenticity of Emotion Judgment

Whether or not the first impression that precedes emotional contagion and influences the final effect of emotional contagion is not clear. A mixed two-factor design was used to investigate this issue. The participants were divided into two matched groups by the Emotional Contagion Scale. Firstly, each participant received a positive evaluation on a teacher or a negative evaluation on another teacher. Different ways of spreading the information were used in two groups. Specifically, one way of spreading the positive or negative evaluation on a teacher was sent out by a fake participant for the experiment group; the other way was to spread the positive or negative evaluation by drawing lots for the control group. After that, positive emotional videos of the teachers' lecture were shown to all participants. Then their first impression on the teachers, authenticity judgement to the teachers' emotion, and the level of emotional contagion from teachers were measured respectively. The results showed that the first impression on the teachers, which could affect students' authenticity judgment to the teacher's emotion, was established in the experiment group, but not in the control group. It means the primacy effect had a significant impact on emotional contagion in the experiment group. However, the first impression on the teacher was not established in the control group, which means the primacy effect had no significant effect on emotional contagion. The path analysis showed that the primacy effect regulated emotional contagion via the authenticity judgment to emotion.
