Research Progress of Auditory Perceptual Abnormalities in Autism Spectrum Disorders and Its Implications for Educational Intervention
Early identification and early intervention for children with Autism Spectrum Disorder(ASD)are critical to their developmental outcomes.The present study analysed 83 relevant papers from 2000-2023,and the results suggested that auditory perceptual abnormalities may be a potential identifier of children with ASD and are evident in infancy and early childhood.Early behavioral abnormalities mainly include auditory overreaction,auditory verbal agnosia,and weak audio-visual integration of speech sounds;early physiological indicators of abnormalities include brainstem structural abnormalities,brainstem functional abnormalities,and auditory cortex functional abnormalities.As children with ASD grow older,they are prone to abnormal behaviors such as auditory sensory seeking,sensitivity to non-verbal sounds,and difficulty in hearing under noise.Auditory perceptual abnormalities are now an important component of autism screening and diagnosis,and their high rate of occurrence is an extremely important reminder for educational interventions.It is suggested that future educational interventions should:(1)identify children with ASD as having auditory overreactions to sounds and be given systematic desensitisation training,or be helped develop the ability to actively block or isolate sounds that cause discomfort;(2)make full use of the preferences of children with ASD and guide them actively process speech sounds;and(3)adopt appropriate audio-visual games to enhance the audio-visual integration ability and ability of selective listening under noise.
