Regulatory aspects of development can best be understood by research that conceptualizes relations between cognition and emotion. The neural mechanisms associated with regulatory processes may be the same as those associated with higher order cognitive processes. Thus, from a developmental cognitive neuroscience perspective, emotion and cognition are dynamically linked and work together to process information and execute action. This article highlights the authors' recent efforts at integrating emotion regulation and cognitive processing during the first year of life by focusing on the methodological criteria outlined by Cole, Martin, and Dennis (this issue), and it discusses the idea that emotion and cognition are an intricately bound developmental process.
