Anxiety is a common problem for children and adults with fragile X syndrome, magnifying their struggles living with an inherited intellectual disability. New UC Davis research could lead to new ways to identify and treat their anxiety at a young age—even in infancy.
The study led by developmental psychologists Jessica Burris and Susan Rivera found that infants and young children with fragile X syndrome, unlike typically developing children, tend to have their attention specifically captured by angry faces rather than happy ones. That sort of “attentional bias” toward angry faces is a pattern associated with anxiety.
In this episode of the Three Minute Egghead podcast, I talk to John Henderson of the UC Davis Center for Mind and Brain about a new paper from his lab that overturns current thinking about visual attention.
It’s usually thought that our eyes are drawn to objects that are salient or “stand out” from the background. But this “magpie theory” of attention is wrong, Henderson says. He and postdoc Taylor Hayes show instead that our eyes are drawn by parts of a scene that have “meaning.”
