Adversity and Emotional Functioning.

Exposure to early adversity has been linked to variations in emotional functioning. To date, however, the precise nature of these variations has been difficult to pinpoint given widespread differences in the ways in which aspects of emotional functioning are defined and measured. Here, more consistent with models of emotional functioning in typically developing populations (e.g., Halberstadt et al., 2001), we propose defining emotional functioning as consisting of distinct domains of emotion expression, perception, knowledge, reactivity, and regulation. We argue that this framework is useful for guiding hypothesis generation about the specific impact of early adversity on children's emotional functioning. We operationalize the construct of emotional functioning, highlight what is currently known about the association between adversity exposure and each domain of emotional functioning, propose potential mechanisms for these associations, and set the stage for future research examining the development of emotional functioning in the context of early adversity. © The Society for Affective Science 2021.
