Study Links Focus on Emotional Expressions to Depression Risk in Children

The study found that depressive symptoms can influence how intensely children focus on emotional faces, with variations based on family history of depression. The Mood Disorders Institute at Binghamton University conducted this research to understand the development of depression in children and adolescents by examining the interplay between family history, emotional experiences, and vulnerability over time.

Brandon Gibb, director of the Mood Disorders Institute and a distinguished professor of psychology, emphasized the importance of observing developing vulnerabilities rather than only studying stable symptoms later in life.

Previous studies have suggested a link between depression and increased attention to sad faces, but it remained unclear whether this biased attention caused depression or was a consequence of it. This new research aimed to explore the reciprocal relationship between depressive symptoms and attention patterns among children.

Kelly Gair, a PhD student at Binghamton and lead author of the study, highlighted the novelty of examining how attentional biases and depressive symptoms affect each other over time. The research team, which included Leslie A. Brick from the University of New Mexico, followed 242 children and their mothers for two years, assessing them every six months.

During assessments, children viewed pairs of faces—one neutral and one displaying an emotion (happy, sad, or angry)—while eye tracking technology recorded where their focus lay and for how long.

The results revealed that the impact of increasing depressive symptoms on attention varied among children, influenced significantly by family history. Children with mothers who had a history of major depressive disorder showed greater attention to sad faces as their own depressive symptoms increased. Gibb noted that these children's ability to divert their attention from sadness diminished as their depressive symptoms worsened.

Conversely, children whose mothers had no history of depression displayed a different trend. As their depressive symptoms grew, they became less attentive to happy faces rather than more focused on sad expressions. Gibb explained that this may indicate a loss of a protective factor related to attention toward positive emotional cues.

These findings suggest that depression may affect emotional attention in varying ways depending on familial risk factors. For some children, sadness becomes harder to overlook, while for others, positive emotions are less engaging.

The research team plans to continue monitoring these children into adolescence, a critical time when depression risk increases significantly. They aim to determine if the identified attention patterns correlate with future depression diagnoses. The paper detailing this study, "Transactional Relations Between Attentional Biases for Affective Stimuli and Depressive Symptoms in Offspring of Mothers With and Without Major Depressive Disorder," was published in the Journal of Psychopathology and Clinical Science.
