A classic topic in developmental psychology is the classification of styles of parenting and their effect on the development of children. We differentiate between four basic styles based on two dimensions, which are the expectations of the parents and the emotional warmth and responsiveness shown towards their children. Authoritarian parents have high demands, but are less responsive. Authoritative parents are expectant and also responsive. Permissive parents have low expectations and high levels of responsiveness. Uninvolved parents have low levels both of demand and of responsiveness.
