Purpose Understand the current situation of the emotional experience and emotional awareness of preschool teachers, explore the impact of pre-service and post-service (grade and teaching age) on the two, and analyze the relationship between the two. Methods In this study, the Toronto Alexithymia Scale was used to measure the emotional awareness of 376 preschool teachers, and the Trait Meta-mood Scale, the Affective Intensity Scale and the Emotional Expressivity Scale were used to measure their emotional attention, emotional clarity, emotional intensity and emotional expression in their emotional experience. Result (1) The emotional experience traits of preschool teachers are at a medium level, and the level of emotional awareness is good. (2) On the emotional attention points, majoring in preschool education students is significantly higher than freshman to junior and teaching experience scored more than one year to five years, senior and teaching experience more than five years in articulation score were higher than freshman to junior score, freshman to junior emotional awareness score higher than senior grade, teaching experience more than one year to five years, five years or more (p’s < 0.05). (3)Emotional attention and emotional clarity are significantly negatively correlated with emotional awareness, while emotional intensity and emotional expression are significantly positively correlated with emotional awareness.Emotional attention and emotional clarity negatively predicted the score of emotional awareness (β = -0.28, -0.70, P < 0.01), emotional intensity and emotional expression both positively predict emotional awareness scores (β = 0.26, 0.29, 0.13, p's<0.05 Conclusion There are significant differences in emotional attention, emotional clarity and emotional awareness among preschool teachers in different grades and teaching ages; the relationship among the dimensions of emotional attention, emotional clarity, and emotional awareness is not completely consistent, but their relationships are similar and need to be further studied.
