- Social anxiety disorder (SAD) typically develops during late childhood or early adolescence, and often runs a chronic course if left untreated. Maladaptive processing of social information has been suggested to contribute to the etiology and maintenance of SAD. Scanpaths are a succession of visual fixations and saccades through which individuals extract information during face perception. Atypically long scanpaths have previously been reported in adults with SAD but no studies have been conducted on youth samples. SAD has previously also been linked to atypical arousal during face processing.ObjectivesThis study aimed to investigate differences in visual attention and arousal to emotional faces comparing children and adolescents with SAD to a non-psychiatric population of youths.MethodsIn one of the largest eye-tracking studies of pediatric SAD to date, children and adolescents with SAD (n = 62) and healthy controls (n = 39) completed a task where they were meant to recognise different emotional expressions in pictures of faces while their eye movements were recorded. The visual scanpath and the pupil dilation response were examined.ResultsYouth with SAD showed restricted scanpaths, suggesting they scanned a more limited part of the face during face perception. Higher pupil dilation was also observed in the children and adolescents with SAD.ConclusionsThe restricted pattern of scanpath observed in youth with SAD is contrary to findings among adults, but similar to what has been reported in neurodevelopmental disorders associated with social interaction impairments such as autism. Restricted scanpaths may partially contribute to the maintencance of social anxiety disorder.DisclosureNo significant relationships.

- Background: Social anxiety disorder (SAD) has its typical onset in childhood and adolescence. Maladaptive processing of social information may contribute to the etiology and maintenance of SAD. During face perception, individuals execute a succession of visual fixations known as a scanpath which facilitates information processing. Atypically long scanpaths have been reported in adults with SAD, but no data exists from pediatric samples. SAD has also been linked to atypical arousal during face perception. Both metrics were examined in one of the largest eye-tracking studies of pediatric SAD to date.Methods: Participants were children and adolescents with SAD (n = 61) and healthy controls (n = 39) with a mean age of 14 years (range 10–17) who completed an emotion recognition task. The visual scanpath and pupil dilation (an indirect index of arousal) were examined using eye tracking.Results: Scanpaths of youth with SAD were shorter, less distributed, and consisted of a smaller number of fixations than those of healthy controls. These findings were supported by both frequentist and Bayesian statistics. Higher pupil dilation was also observed in the SAD group, but despite a statistically significant group difference, this result was not supported by the Bayesian analysis.Conclusions: The results were contrary to findings from adult studies, but similar to what has been reported in neurodevelopmental conditions associated with social interaction impairments. Restricted scanpaths may disrupt holistic representation of faces known to favor adaptive social understanding.
