    Input: Few behavioral indices of risk for autism spectrum disorders ( ASD ) are present before 12 months , and potential biomarkers remain largely unexamined . This prospect i ve study of infant siblings of children with ASD ( n = 16 ) and low-risk comparison infants ( n = 15 ) examined group differences in event-related potentials ( ERPs ) indexing processing of facial positive affect ( N290/P400 , Nc ) at 9 months and their relation to joint attention at 15 months . Group differences were most pronounced for subtle facial expressions , in that the low-risk group exhibited relatively longer processing ( P400 latency ) and greater attention re source allocation ( Nc amplitude ) . Exploratory analyses found associations between ERP responses and later joint attention , suggesting that attention to positive affect cues may support the development of other social competencies Past research has found evidence for face and emotional expression processing differences between individuals with Asperger 's syndrome ( AS ) and neurotypical ( NT ) controls at both the neurological and behavioural levels . The aim of the present study was to examine the neurophysiological basis of emotional expression processing in children and adults with AS relative to age- and gender-matched NT controls .  High-density event-related potentials were recorded during explicit processing of happy , sad , angry , scared , and neutral faces .  Adults with AS were found to exhibit delayed P1 and N170 latencies and smaller N170 amplitudes in comparison to control subjects for all expressions . This may reflect impaired holistic and configural processing of faces in AS adults . However , these differences were not observed between AS and control children . This may result from incomplete development of the neuronal generators of these ERP components and /or early intervention 
    Output:
    
HIGHLIGHTSIndividuals with Autism Spectrum Disorder present with atypical gaze and cortical activation to facially expressed emotions .
Individuals with Autism Spectrum Disorder may use compensatory strategies during facial emotion recognition .
Individuals with Autism Spectrum Disorder may employ self‐regulatory strategies during facial emotion recognition .
Eye tracking ( ET ) and electroencephalography ( EEG ) provide insights in to the attentional and neurological correlates of performance , and may therefore provide insight in to the mechanisms underpinning FER in ASD .
Findings indicate divergence of visual processing pathways in individuals with ASD .
Altered function of the social brain in ASD impacts the processing of facial emotion across the developmental trajectory , result ing in observable differences in ET and EEG outcomes
