MRI Research Could Help Withdrawn Children

A Stony Brook-led study using functional-MRI brain scanning could be a key step toward helping withdrawn children to interact with their peers and avoid anxiety disorders.

Led by Stony Brook University psychologist Johanna M. Jarcho, PhD, the study shows that certain areas of the brain have higher activity in children who are socially withdrawn or reticent compared to children who are not withdrawn. The research entailed fMRI scanning of children while they experienced a “cartoon classroom” that featured themselves as the new student in the school involved in various social interactions.

The findings, published online first in Psychological Science, provide a better understanding of the brain activity of socially withdrawn children and could help form a foundation to teach children how to think differently about social interactions and thus prevent further socially withdrawn behavior or social anxiety.

Social reticence is expressed as shy, anxiously avoidant behavior in early childhood. Some mental health professionals believe that social reticence in childhood and pre-teen years is a precursor to more socially withdrawn behavior and social anxiety that develops through the teen years and adulthood.

In the paper titled “Early-Childhood Social Reticence Predicts Brain Function in Preadolescent Youths During Distinct Forms of Peer Evaluation,” Dr. Jarcho, an assistant professor in the Department of Psychology at Stony Brook University, and colleagues evaluated 53 children by way of fMRI. The children were part of a study beginning at two years of age with follow-ups at multiple ages to age 11. Thirty of the children were evaluated as those functioning with high social reticence; 23 were considered to have low social reticence.

The research team created a novel interactive paradigm around a virtual classroom in a cartoon form. Each of the 11-year-old children created an avatar character of himself or herself and completed an online personality profile. The experimenters created other characters for the child to interact with, such as the “unpredictable kid,” “bully,” or “nice student.” While undergoing fMRI, social interactions inside the classroom were played out, with each child reacting to these social interactions with their avatar character.


Dr. Jarcho explains her research methods for LabTV.

“Few techniques have been able to test the effects of such nuanced social landscape on brain function during real-time, ongoing, peer-based interactions where peers embody distinct social qualities,” said Dr. Jarcho. “This paradigm proved very effective in mapping brain activity of pre-teens who are socially reticent and appears to be a valuable tool for ongoing research.”

The scanning revealed that high (but not low) social reticence predicted greater activity in the dorsal anterior cingulate cortex and left and right insula, brain regions implicated in processing salience and distress. High social reticence was also associated with negative functional connectivity between insula and ventromedial prefrontal cortex, a region commonly implicated in affect regulation. Also, participants with high social reticence showed increased amygdala activity but only during feedback from the “unpredictable” peers in the cartoon classroom.

The findings provide scientists with a measure of brain functioning of pre-teens with high social reticence. A critical next step is to isolate neural circuits that promote risk for or resilience against expressions of psychopathology related to high social reticence.

Dr. Jarcho and colleagues are currently conducting interviews with the same group of 53 participants who are now approaching their teens. The idea is to determine if the pattern of brain function that differentiated pre-teens with high and low childhood social reticence also predicts expression of social anxiety symptoms.

Co-authors on the paper include scientists from Stony Brook University, the University of Maryland, the National Institute of Mental Health, University of Illinois, University of Haifa, University of Waterloo, Nationwide Children’s Hospital in Ohio, and Ohio State University.
