This study is a report on the emotional and cognitive impact of hypnotic suggestion on EFL teachers' practices. Twenty-five EFL teachers participated in two hypnotic suggestion sessions plus a self-suggestion training class to enhance their emotional and cognitive experiences. To understand teachers' emotional state, pre-intervention interviews were used, and post-intervention interviews were employed to assess the effects of the hypnotic suggestion intervention. Through content analysis, we found that the emotional experience of novice and expert teachers differed significantly. Furthermore, the effect of hypnotic suggestion on teachers' emotions, cognition, and practice was significant and conducive to change in their perspectives toward hypnotic suggestion programs. Thorough theoretical and practical implications are discussed.
