Language and Social Understanding Systems Exist Separately in Children’s Brains from the Start, New Research Finds

When children listen to a story, they do more than just process the meaning of words; they also visualize the emotions and beliefs of the characters. Scientists refer to these two distinct abilities as “language processing” and “theory of mind” (the ability to understand another person’s mental state).
Historically, researchers believed that these two systems were intertwined in early childhood and only diverged as a child matured. However, new research from The Ohio State University reveals that these systems are already functioning independently in children as young as three years old.
The research team conducted MRI brain scans on 42 children between the ages of 3 and 9. To ensure the children remained comfortable during the scans, the team utilized practice sessions and allowed them to watch cartoons and listen to speech that stimulated social cognition.
The study found that even at age three, the brain’s language regions responded exclusively to speech sounds, while social processing regions responded specifically to understanding a character’s emotions.
Rather than becoming more distinct as children grew older, these two systems remained stable in their independent functions. Follow-up scans conducted one year later confirmed that this neurological structure remained consistent over time.
The findings show that the language system is connected to the frontal and motor-related regions of the brain, whereas the social system is linked to regions associated with psychological reasoning and social thought.
This discovery shifts our fundamental understanding of child development. It suggests that language proficiency does not automatically equate to strong social understanding. Conversely, a child with delayed speech development does not necessarily lack the ability to empathize or understand the feelings of others.
The brain appears to run these two functional systems—understanding words and understanding people—in parallel and independently from the very beginning. This research was originally published in the journal Communications Biology.
