COMMENTARIES The Role of Parents in Children’s Psychological Development

This article reviews the three major ways parents influence children: direct interaction, identification, and transmission of family stories. This essay summarizes some of the relevant empiric data in support of this claim and describes the operation of other mechanisms that also contribute to the child’s development. Pediatrics 1999;104:164–167; parental influence, children. The profile of cognitive abilities, beliefs, ethical values, coping defenses, and salient emotional moods that characterizes each child at each developmental stage is the result of diverse influences operating in complex ways. Most students of human development agree that the most important determinants of the different profiles include 1) the inherited physiologic patterns that are called temperamental qualities, 2) parental practices and personality, 3) quality of schools attended, 4) relationships with peers, 5) ordinal position in the family, and, finally, 6) the historical era in which late childhood and early adolescence are spent.1 Each of these factors exerts its major influence on only some components of the psychological profile and is usually most effective during particular age periods. For example, the quality of social relations with peers affects primarily the child’s beliefs about his/her acceptability to others and has its major effect after school entrance.2 By contrast, parental conversations with the child, and especially naming unfamiliar objects, affect the child’s future verbal talents and have maximal effect during the first 6 years of life.3 Current discussions of the consequences of parental practices, whether in the media or in professional journals, favor one of two positions. One awards seminal power to parental factors; the other minimizes the family. The advocates of attachment theory, for example, propose that the relationships established between an infant and its caretakers during the first 2 years of life have a permanent effect on the child’s future.4 But Harris’s recent book, The Nurture Assumption, makes the opposite claim by arguing that parents have little or no permanent influence on their child’s future personality.5 Although the attachment theorists take too strong a position, I side with a majority of developmental scholars who, in disagreement with Harris, believe that parents do affect their child’s psychological growth. This article summarizes what most developmental scientists believe to be the major effects of parents on children. It is important to appreciate, however, that some of these effects are difficult to quantify and, as a result, scholars working in this domain are caught between two opposing imperatives. On the one hand, they recognize that conclusions must be based on empiric evidence; if one does not have valid measurements, one should be cautious. On the other hand, investigators also recognize the error of awarding significance only to statements that rest on objective measurements. Because the current Zeitgeist is more positivistic than it was a half-century earlier, contemporary scientists usually have ignored important causative conditions that are subtle in their expression. PARENTAL INFLUENCE: DIRECT INTERACTIONS Parents can affect their children through at least three different mechanisms. The most obvious, and the one easiest both to imagine and to measure, involves the consequences of direct interactions with the child that could be recorded on film. For example, a mother praises a 3-year-old for eating properly, a father threatens the loss of a privilege because a child refuses to go to bed, a parent names an unfamiliar animal in a picture book. These everyday events that involve the rewarding of desirable actions, the punishment of undesired ones, and the transfer of knowledge from parent to child have a cumulative effect. Failure to discipline acts of disobedience and/or aggression is correlated with children’s asocial behavior.6 Display of interest in a young child’s activities is correlated with greater levels of responsivity in the child.7 However, these first-order effects can have second-order consequences that appear later in life. A 7-year-old with a more extensive vocabulary than her peers, because her parents encouraged language development 5 years earlier, will master the tasks of the elementary grades more easily and, as a result, perceive herself as more competent than her peers. This belief is likely to embolden her to resist domination by others and, perhaps, motivate the initiation of unusually challenging tasks. The 7-year-old who was not chastised for aggressive behavior earlier or who had abusive or overly intrusive parents is likely to be aggressive with peers.
