Studying hot executive function in infancy: Insights from research on emotional development

Recent calls have urged to bridge the fields of emotional and cognitive development to advance theoretical and empirical pursuits. Yet, despite notable overlap between research on executive function and emotion regulation, a uniting theory that informs future avenues of research is lacking. Infants are known to lack emotion regulation skills, as they are developing the abilities to regulate their emotions and coordinated responses. However, the field of emotional development demonstrates that at an early age, infants are adept at regulating their behaviors in response to others emotional reactions. Moreover, although classic delay of gratification tasks are fairly ecological measures, rarely are rules expressed to infants without emotions. This paper draws from recent interest in hot executive function to link infancy research on executive function and emotion. Hot executive function lends itself as a useful construct in this endeavor because it unites the study emotion and executive function. We offer a perspective that refines hot executive function within prominent emotion theories while discussing infant executive function and emotion empirical pursuits. Our perspective presents reliable paradigms from the field of emotional development to serve as tools for studying the development of hot executive function.
