Summary:
- This study found that toddlers, around 2 years old, tend to be happier when they give treats to others rather than receiving treats themselves.
- The researchers observed toddlers' reactions when they were given the choice to keep a treat for themselves or give it to another child. The toddlers showed more positive emotions when they chose to share the treat.
- This suggests that even at a young age, children have a natural inclination towards prosocial behavior and caring for others, which can be an important foundation for empathy and cooperation as they grow older.
