Preschoolers’ cognitive skills predict their developing moral self

Abstract

Although individual differences in children’s moral self-concept emerge during early childhood and predict future behavioral outcomes, the cognitive skills underlying the development of the moral self have received little attention. We addressed this gap with a longitudinal sample of 106 children (M_age = 52.78 months, SD = 6.61, range = 37–64 at Time 1) living in urban economic deprivation. In the fall, children completed interviews on the moral self as well as hot and cool executive function (EF) tasks, a five-task theory of mind (ToM) battery, and a receptive verbal assessment. Approximately 6 months later, children again completed the moral self interview. Results from a series of latent change score models, controlling for age and parents’ education, demonstrate that different aspects of the moral self were supported in different ways, and at different times, by aspects of cognition. For instance, the aggressive moral self was initially predicted by both cool and hot EF, whereas change was predicted by cool EF. In comparison, the socioemotional moral self was initially predicted by cool EF, as were changes over time. The initial instrumental helping moral self was predicted by ToM. Findings suggest that a multidimensional moral self may be best enhanced by a multipronged approach to cognitive support.
