Adolescents are in the critical period of shaping their self-knowledge, self-esteem and selfconcept,and it is also the peak period for all kinds of problematic behaviors. Children in this periodneed the love and care of society and their families. However, due to the popularity of the Internet andthe development of smartphones, “low-touch people” can be found everywhere at home, and “low-touchbehavior” has become commonplace. This phenomenon refers to the fact that parents are so preoccupiedwith their cell phones when interacting with their children that they neglect or leave their children outin the cold. Nowadays, parents’ “head-down behavior” is regarded as a new type of family risk factor thataffects the development of children and adolescents, and has received more and more attention. This papersummarizes the research progress on parental “head-down behavior”, adolescents’ core self-evaluations,and the relationship between the two at home and abroad for the reference of related researchers.
