The emotions and affective factors of teachers play quintessential roles in academic contexts as they influence almost all aspects of their profession. T provide a theoretical review of some psychology constructs of teachers in this area, this study examines the psychological wellbeing, mindfulness, and immunity of teachers as three novel variables. More specifically, this study presents the definitions, dimensions, theories, and frameworks related to this domain drawing on positive psychology, complexity/dynamic systems theory, self-organization process, reflexive self-consciousness theory, integrative awareness theories, and mindfulness framework. These theoretical underpinnings explain the constructs and the way they function in second language education. Then, to provide evidence and justify the findings and propositions, empirical studies on each of the variables are reviewed. Finally, implications, research gaps, and suggestions for future inquiries are offered to interested researchers.

Considering the significant contribution of teachers’ professional triumph in the prosperity of students, the current study aims to investigate the existence of any relationship among three factors influencing teachers’ success: immunity, mindfulness, and engagement. Furthermore, we attempt to investigate whether English as a foreign language (EFL) teachers’ immunity and mindfulness can predict their work engagement. To this end, a Likert-scale questionnaire including items on teacher immunity, mindfulness, and work engagement was distributed to 582 EFL teachers in China through the WeChat application by employing a convenient sampling. To analyze the collected data, the Spearman Rho correlation index and linear multiple regression analysis are employed. The findings are that there does exist an indication of a direct relationship among EFL teachers’ immunity, mindfulness, and work engagement. Also, it is found that immunity and mindfulness can predict EFL teachers’ work engagement. The current study’s findings support the necessity of training language teachers to cope with the EFL context adversities.

As integral to the EFL learners' achievement and intellectual development, good language teachers need to be familiar with the influential factors hindering or promoting their success. Positive psychology paying attention to positive traits highlights the factors that boost performance. In this line, by taking boosters of being a successful teacher, the aim of the current study is to consider the interplay between Chinese EFL instructors' professional success, workplace buoyancy, and cognitive flexibility. Then, it is considered whether EFL teachers' buoyancy and cognitive flexibility can predict success. Accordingly, 328 Chinese EFL teachers were conveniently selected to participate in this study. To analyze the collected data, multiple regression analysis and Spearman Rho correlation index as well as ANOVA were employed. The findings are an indication of a direct and significant correlation and coaction among EFL teachers' cognitive flexibility, workplace buoyancy, and professional success. Additionally, the results indicate that the cognitive flexibility of EFL teachers can be one of the significant predictors of success in their profession. Our findings imply that teachers need to enhance their positive personality traits such as cognitive flexibility and buoyancy to be successful in their profession.
