Intact Neural Responding to Hearing One's Own Name in Children with Autism

Diminished responding to one's own name is one of the strongest and earliest predictors of autism. However, research on the neural correlates of this response in autism is scarce. Here we investigate neural responses to hearing the own name in school-aged children with and without autism. Thirty-four children with autism and 33 without autism (ages 7-13) were presented with three categories of names (own name, close other's name and unknown other name) as task-irrelevant deviant stimuli in an auditory oddball paradigm, while EEG was recorded. In line with previous findings, parietal P3 amplitudes for the own name were enhanced compared with a close other's name. Older children showed a stronger self-specific effect than younger children. However, this self-preferential effect was not different between groups, despite the fact that parents of children with autism reported significantly less own-name responsiveness in daily life. Neither the N1 component or SON negativity showed self-specific effects. In school-aged children, only the parietal P3 component, and not the N1 or SON negativity, appears to be enhanced for the own name as compared to a close other's name. Age seems to have an effect on the own name modulation of the P3 amplitude, which may explain the relatively small overall effect size. Against expectations, groups did not differ on this self-specific effect. Further research into neural and behavioral responses to hearing one's own name in autism, across different age groups, is warranted.
