When babies as young as 6 months old were presented with naughty(いたずらな、言うことを聞かない), neutral, and nice toys, they overwhelmingly chose to play with the nice one. Researchers showed the infants a googly-eyed wooden toy repeatedly trying to climb a hill. They then brought in another googly-eyed toy to either help the first puppet over the hill or push it backward. After seeing the interaction, nearly every baby chose to play with the helpful toy. This suggests that even at a very young age, infants are able to make social judgments that distinguish between helping and hurting and that these distinctions may serve as the foundation for moral evaluations as children develop and grow.
