In the early empirical research on the socialization of adolescents, researchers began to describe the parental upbringing in dimensions. For example, the earliest researcher American psychologist Symonds (PMSymonds, 1939), he divided the parental upbringing into two dimensions: "accepting-refusing" and "dominating-obeying", and studied to explain the impact of the parenting on children ; Baldwin (ALBaldwin, 1955) is divided into two dimensions of "emotional warmth-hostility" and "attachment-interference"; ESSchaefer (1959) is divided into two dimensions of "love-hostility" and "autonomy-control"; WCBecker (1964) is divided into two dimensions: "warmth-hostility" and "restriction-tolerance".
