Mapping Emotion Recognition in Children

Researchers discovered children's ability to process emotional cues is largely established by the time they start school. Analyzing brain scans from children aged five to 15, the study revealed that such brain activity becomes increasingly similar to their peers' as they reach adolescence. The research emphasizes the importance of early intervention to address issues related to understanding emotional cues.
