The ontogeny of a moral stance: Developmental changes in coherence among facets of morality in young children.

This longitudinal study examined how different aspects of moral behavior become more integrated as children develop from ages 2.5 to 3.5 years. Researchers observed 94 toddlers' responses to scenarios involving harm and property destruction, measuring arousal, protest, evaluations, and punishment judgments. The study found that moral responses were weakly related in toddlerhood but became more consistent and integrated over time.

Key points

• Different facets of moral behavior (arousal, protest, evaluations, punishment judgments) showed weak interrelations in toddlerhood
• Moral facets became increasingly integrated between ages 2.5 and 3.5 years
• Children showed increased consistency in responses across scenarios as they developed
• Sample was predominantly White and middle-to-high socioeconomic status
• Study used longitudinal design with assessments at two time points

Limitations

This study examines the fundamental developmental psychology of moral cognition rather than child well-being outcomes or the effectiveness of interventions to improve children's health, safety, or development. The findings describe how moral reasoning emerges but do not evaluate whether this development translates to better outcomes for children.
