Most parents notice when their child seems unusually quiet, withdrawn, or less enthusiastic than normal. But some of the earliest signs of mental health struggles may appear long before those changes become obvious.
According to researchers at Binghamton University in New York, a child’s visual attention to emotional expressions could provide important clues about their future risk of depression. The findings were published in the Journal of Psychopathology and Clinical Science.
Hidden signals
The research team followed 242 children and their mothers over a two-year period. Every six months, participants returned for assessments designed to measure emotional development and mental health, reports Science Daily.
As part of the study, children viewed images of faces showing different emotions while eye-tracking technology recorded exactly where their attention was directed.

Researchers wanted to understand whether depressive symptoms influence what children notice in the world around them and whether family history affects those patterns.
Family history matters
The results revealed a clear difference between children depending on whether their mothers had previously experienced major depression.
Among children with a family history of depression, increasing depressive symptoms were linked to greater attention toward sad facial expressions. Researchers believe these children may become more sensitive to negative emotional cues as symptoms develop.
The findings suggest that depression does not simply affect mood. It may also influence how young people process the emotions they encounter every day.

Different pattern
Children whose mothers had no history of depression showed a different response.
Rather than focusing more on sadness, they gradually spent less time looking at happy faces as depressive symptoms increased. Researchers believe this may represent the loss of a natural protective factor that supports emotional well-being.
- Higher-risk children became more focused on sad expressions
- Lower-risk children paid less attention to happy expressions
The team is continuing to follow the participants into adolescence to determine whether these attention patterns can predict future clinical depression and help identify vulnerable children earlier.
