Ten adults with ASD rated word and picture stimuli on…

Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual…

The groups had comparable oral and written language skills and…
