The emergence and consolidation of self-control from eighteen to thirty months of age: normative trends and individual differences

Child Dev. 1984 Jun;55(3):990-1004.

Abstract

This study is a descriptive report of the capability to exercise self-control in very young children. 2 aspects of self-control were assessed (delay/response inhibition in the presence of an attractive stimulus and compliance with maternal directives in a cleanup task) for 72 children between the ages of 18 and 30 months. The results indicated that both aspects of self-control show age-related increases. However, a factor analysis of the behaviors observed in the cleanup task suggested that compliance could not be adequately described with a unitary, bipolar dimension (noncompliance vs. compliance). 2 patterns of non-compliance were observed, and 1 of these also increased with age. Cross-task consistency for the delay measures) and coherence across the 2 aspects of self-control showed a positive relationship with increasing age. Finally, correlational analyses of the self-control measures and developmental test data showed that individual differences in self-control were associated with differences in cognitive-developmental status (DA). The results are interpreted as evidence that the achievement of self-control can be considered as a major developmental accomplishment and as evidence that individual differences in self-control emerge and are consolidated during the second and third years of life.
