“…Not surprisingly, therefore, much of the work with these children as participants has focused on clinically relevant questions (e.g., rates of psychopathology among these groups), rather than questions about basic developmental science (though see Zucker et al, 1999). Even when the existence of these children is mentioned in reviews of gender development (e.g., Martin, Ruble, & Szkrybalo, 2002;Ruble, Martin, & BEYOND DISCRETE CATEGORIES Berenbaum, 2006), their experiences rarely make it into broader discussions of gender development (Liben, 2016). This separation occurs despite the fact that focusing on these less common populations may be especially insightful to our theory development.…”
