This document discusses four main parenting styles: permissive, uninvolved, authoritarian, and authoritative. It outlines the characteristics of each style and examines their typical psychological and biological effects on children. Authoritarian parenting is low in nurturance but high in control, and can lead to issues like low self-esteem and stress in children. Authoritative parenting, which is high in all areas, tends to produce children with confidence and self-control. An uninvolved style causes neglect, while permissive parenting lacks discipline. Overall, the authoritative approach generally has the most positive outcomes.
