Examining Systems of Influence and Breaking Methodological Barriers to Create Usable Knowledge

The goal of this special section of Mind, Brain, and Education is to provide a platform on which practical insight can be gained from new empirical research on hormones and behavior in development. In this second installment we highlight two articles and a commentary, which broaden our focus beyond cortisol and stress system functioning to other hormone systems and tackle some of the methodological barriers to making research–practice connections in this domain. Articles specifically look at biology by environment interactions and offer nuanced procedures for hormone collection so as to allow for investigation into the day‐to‐day and even within day dynamic functioning of targeted systems.
