“…The Special Section consists of eight articles that strikingly represent the breadth and depth of developmental research in substantive topic, methodological approach, and target population. The articles include experimental studies with young children (Fish et al, 2023; Stengelin et al, 2023) and chimpanzees (Engelmann et al, 2023), assessments of the efficacy of interventions with children and adolescents (Ceccon et al, 2023; Cipriano et al, 2023; Gilligan‐Lee et al, 2023), work focused on underrepresented populations (Ceccon et al, 2023; Cimpian et al, 2023; Leer et al, 2023), a study consisting of national public data (Cimpian et al, 2023), a natural experiment (Leer et al, 2023), and a meta‐analysis (Cipriano et al, 2023). A major goal of the Special Section was to demonstrate the broad applicability of RRs for developmental research—that they are not solely for laboratory experiments—and the eight articles collectively met that goal beyond what we could have hoped for.…”
