Autism Spectrum Disorder (ASD) and epilepsy represent a comorbidity that negatively influences the proper development of linguistic competencies, particularly in receptive language, in the pediatric population. This group displays impairments in the auditory comprehension of both simple and complex grammatical structures, significantly limiting…

Whilst enhanced perception has been widely reported in individuals with Autism Spectrum Disorders (ASDs), relatively little is known about the developmental trajectory and impact of atypical auditory processing on speech perception in intellectually high-functioning adults with ASD. This paper presents data on perception of complex tones and…

This study compared 20 children (ages 8-14) with either autism or receptive developmental language disorder (RDLD) to 10 controls in their ability to detect frequent and infrequent randomly presented auditory stimuli. Only the children with autism demonstrated an abnormally small amplitude of the P3b, a component of the event-related brain…

The study examined the performance of 19 pairs of autistic and nonautistic (but with a language delay of at least six months) children on the Test for Auditory Comprehension of Language. Results indicated no significant differences between groups or between sexes within groups in receptive language skills. (Author/DB)

The study investigated two neurophysiologic components of event-related brain potential during auditory and visual target detection tasks with 11 non-retarded autistic children, 9 retarded autistic children, and 16 normal subjects, aged 15-19. Results were consistent with the hypothesis that non-retarded autism involves abnormal attentional and…
