The belief of emotional plasticity has individual difference. In order to examine how implicit
theories of emotion were associated with well-being via emotional regulation strategies, current research
recruited 533 college students to complete relevant questionnaires. Results revealed that individuals who
recognize that emotions are malleable have higher levels of well-being (higher life satisfaction and more
positive emotions, and less negative emotions, anxiety, and depression), and they are more flexible in
emotional regulation (more use of cognitive reappraisal and expression inhibition). And we found the
cognitive reappraisal plays a mediating role in the influence of emotional entity theory on the positive
indicators of well-being. Current research verified the domain specificity of implicit theories in emotion,
and the theoretical and practical implications are discussed.
