Expertise as a unifying framework for individual differences in the mental representation of emotional experience
Expertise refers to outstanding skill or ability in a particular domain. In the domain of emotion, expertise refers to the observation that some people are better at a range of competencies related to understanding, experiencing and managing emotions, and these competencies may help them lead healthier lives. Individual differences in emotional expertise are represented by a wide variety of psychological constructs, including emotional awareness, emotional clarity, emotional complexity, emotional granularity, and emotional intelligence. These constructs derive from different theoretical perspectives, highlight different competencies, and are operationalized and measured in different ways. The full set of relationships between these constructs has not yet been considered, hindering scientific progress and the translation of these findings to aid mental and physical well-being. In this paper, we use a scoping review procedure to integrate these constructs within a shared conceptual space. Using domain-general accounts of expertise as a guide, we build a unifying framework for emotional expertise, and apply this to constructs that describe how people understand and experience their own emotions. Our approach offers opportunities to identify potential underlying mechanisms of individual differences in emotion, thereby encouraging future research on those mechanisms as well as on educational or clinical interventions.
