A new longitudinal study suggests that the way children pay attention to emotional facial expressions may provide an early indicator of depression risk.

Researchers followed 242 children and their mothers over a two-year period, assessing them every six months. During each visit, children viewed pairs of faces on a screen, one neutral and one emotional (happy, sad or angry). Eye-tracking technology provided an objective measure of attention by recording where children looked and how long they focused on each face.

The findings showed that increasing depressive symptoms in the children changed their attention patterns, but the effect depended on family history.

Children whose mothers had experienced Major Depressive Disorder (MDD) – a specific type of severe depression- became increasingly focused on sad faces as their own depressive symptoms increased. This suggests an attentional bias towards negative information. In contrast, children whose mothers had no history of MDD spent less time looking at happy faces when depressive symptoms increased. Rather than focusing more on negative information, these children appeared to pay less attention to positive information.

Attentional bias towards sad faces reflects a tendency to focus on negative information, which is a form of distorted information processing. The reduced attention to happy faces may also reflect negative thinking biases commonly associated with depression. What this study cannot determine is whether the studied effects are caused by genetic inheritance, environmental influences or growing up with a depressed parent, or a combination of both of these factors. One possible explanation which researchers have put forward is that children of mothers with depression may be exposed to sad emotional expressions more frequently, making these cues more noticeable and influential.

Researchers are continuing to follow the children in the study as they approach adolescence. The ultimate goal is to study whether these attention patterns contribute to a higher likelihood of depression in adulthood.
