Summary:

- The study found that by the age of 3, children can anticipate others' actions through the mirror neuron system, which allows them to understand and predict the behavior of others.
- Researchers used electroencephalography (EEG) to measure brain activity in young children as they observed and anticipated simple actions performed by an adult.
- The findings suggest that the mirror neuron system, which is involved in action understanding and prediction, is already functional in young children, allowing them to better navigate their social world.
