Eye Tracking Reveals Early Depression Clues in Children

- Binghamton University researchers tracked 242 children and their mothers over two years with assessments every six months, using eye-tracking to measure attention when kids viewed pairs of neutral and emotional (happy, sad, or angry) faces.
- Children whose mothers had a history of major depressive disorder grew increasingly fixated on sad faces as their own depressive symptoms rose, with Brandon Gibb saying they "lose their ability to pull their attention away from the sad things around them."
- Children whose mothers had no depression history showed the opposite pattern — spending less time on happy faces as depressive symptoms increased, which Gibb described as depression "eroding a protective factor."
- Lead author Kelly Gair, a PhD student, said children of depressed mothers may be exposed to more facial displays of sadness, making sad expressions "even more salient" when those children experience depression themselves.
- The study, published in the Journal of Psychopathology and Clinical Science, is the first to examine the transactional — mutually predictive — relations between attentional biases and depressive symptoms over time in children, according to Gair.
- Researchers are continuing to follow the cohort into adolescence to determine whether these distinct attention patterns predict a higher likelihood of developing clinical depression later in life.
Why it matters: This is the first study to document that attention biases and depressive symptoms predict each other over time in children, not just co-occur. The 242-child cohort will be followed into adolescence to test whether the two distinct gaze patterns — increased focus on sadness in high-risk kids, lost attention to happiness in low-risk ones — predict clinical depression onset, a prerequisite for any future eye-tracking-based screening in at-risk youth.
