Diana Baumrind was an American clinical and developmental psychologist best known for her research on parenting styles. She identified three primary styles: authoritative, authoritarian, and permissive. Her work has significantly influenced the field of psychology, particularly in understanding how different parenting approaches affect child development. Baumrind's research emphasized the importance of balancing responsiveness and demandingness in parenting. She later added a fourth style, neglectful, which describes parents who are uninvolved in their children's lives. Her findings have been widely cited in studies related to child behavior, education, and family dynamics.
