RESUMO
Early recognition of negative emotions is considered to be of vital importance. It seems that children with attention deficit hyperactivity disorder have some difficulties recognizing facial emotional expressions, especially negative ones. This study investigated the preference of children with attention deficit hyperactivity disorder for negative [angry, sad] facial expressions compared to normal children. Participants were 35 drug naive boys with ADHD, aged between 6-11 years, and 31 matched healthy children. Visual orientation data were recorded while participants viewed face pairs [negative-neutral pairs] shown for 3000ms. The number of first fixations made to each expression was considered as an index of initial orientation. Group comparisons revealed no difference between attention deficit hyperactivity disorder group and their matched healthy counterparts in initial orientation of attention. A tendency towards negative emotions was found within the normal group, while no difference was observed between initial allocation of attention toward negative and neutral expressions in children with ADHD. Children with attention deficit hyperactivity disorder do not have significant preference for negative facial expressions. In contrast, normal children have a significant preference for negative facial emotions rather than neutral faces
