Scientists talked about the connection of depression with children's attention to sad faces.

Children whose mothers experienced depression tended to focus on sad faces longer as their own depressive symptoms worsened. This conclusion was reached by researchers at the University of Vermont, who observed 242 children and their mothers for two years. About how the family history of depression may be related to the peculiarities of attention in children — in the material "Izvestia".

Sadness began to attract the attention of children

The study involved 242 children and their mothers. The researchers followed the families for two years and assessed the children's depressive symptoms every six months, as well as their attention to emotional expressions.

To do this, the children were shown pairs of faces with different expressions — neutral, happy, sad or angry. Using gaze tracking technology, the researchers recorded how long the child looked at each image. The work was published in the Journal of Psychopathology and Clinical Science (JPCS).

In children whose mothers had a history of major depressive disorder, the increase in their own depressive symptoms was due to the fact that they kept their attention on sad faces longer.

Happy faces stopped attracting attention.

In children whose mothers had no history of depression, scientists found a different pattern. When depressive symptoms increased, they did not start looking at sad faces more often. Instead, the children in this group paid less attention to happy facial expressions. Researchers consider attention to positive emotional signals as a potentially protective factor.

Thus, the relationship between depressive symptoms and attention patterns differed depending on whether the mother had a history of major depressive disorder.

The authors of the work do not claim that a decrease in attention to happy people directly causes a deterioration in the condition. They consider the discovered pattern as one of the features accompanying changes in depressive symptoms.

Scientists have tracked the changes over time

Previous studies have already shown a link between depression and how a person perceives emotional facial expressions. However, it remained unclear what was happening earlier: changes in attention accompany an increase in depressive symptoms, or the very features of attention may precede them.

In the new work, the researchers evaluated both indicators several times over the course of two years. This made it possible to compare changes in depressive symptoms with subsequent changes in attention and vice versa.

Therefore, the authors were able to study the relationship of these indicators over time, but the data obtained by themselves do not prove that attention disorders cause depressive symptoms.

Family history has changed the reaction to sad signals

The presence of depression in the mother turned out to be an important factor that distinguished the two groups of children. In participants with such a family history, increased depressive symptoms were accompanied by greater attention to sad faces. The researchers suggest that children may have experienced more signs of sadness when interacting with their mother. Because of this, such emotional signals could become more noticeable to them.

At the same time, Geir emphasizes that this is only one of the possible interpretations of the results. The study did not directly examine how children's interactions with their mothers shaped their attention to emotional expressions. Therefore, the authors consider the family history of depression as a factor related to differences in children's reactions, rather than as a proven cause of the identified behavior.

Scientists will continue to monitor children

The researchers plan to continue monitoring the participants to find out whether the discovered attention patterns are associated with the subsequent development of depression.

Adolescence is of particular importance to the authors. It is during this period that many vulnerability factors related to mental health continue to form, so long-term observation can help to understand how depressive symptoms and attention patterns change.

Thus, the current results describe a link between depressive symptoms, a family history of depression, and attention to emotional expression, but they do not allow us to determine in advance which child will develop depression later.
