Positive language is an important branch of positive psychology and an effective extension of the application field of positive psychology. Most foreign scholars integrate the study of positive language into the research framework of linguistic psychology. This study selects the method of multi-factor experiment to complete the language quotient ability test and emotional intelligence test of 36 middle school students. Through the two tests before and after and the experimental processing of the subjects in the middle four months, the dimensions of the positive language quotient model (verbal emotion expression ability, verbal logic ability, verbal understanding and expression ability, physical expression ability) and the factors that can affect the level of positive language ability (emotional intelligence level) are finally obtained. Reading, sports and singing have a good regulating effect on people’s emotions. Similarly, reading, sports and singing are more effective in enhancing people’s positive language expression ability, while memorizing and writing vocabulary are less effective.
