2 Pitch Processing in Autistic Mandarin-Speaking Children with Hypersensitivityand Hypo-Sensitivity: An Event-Related Potential Study

Authors: Kaiying Lai, Suiping Wang, Luodi Yu, Yang Zhang, Pengmin Qin

Abstract:

Abnormalities in auditory processing are one of the most commonly reported sensory processing impairments in children with Autism Spectrum Disorder (ASD). Tonal language speaker with autism has enhanced neural sensitivity to pitch changes in pure tone. However, not all children with ASD exhibit the same performance in pitch processing due to different auditory sensitivity. The current study aimed to examine auditory change detection in ASD with different auditory sensitivity. K-means clustering method was adopted to classify ASD participants into two groups according to the auditory processing scores of the Sensory Profile, 11 autism with hypersensitivity (mean age = 11.36 ; SD = 1.46) and 18 with hypo-sensitivity (mean age = 10.64; SD = 1.89) participated in a passive auditory oddball paradigm designed for eliciting mismatch negativity (MMN) under the pure tone condition. Results revealed that compared to hypersensitive autism, the children with hypo-sensitivity showed smaller MMN responses to pure tone stimuli. These results suggest that ASD with auditory hypersensitivity and hypo-sensitivity performed differently in processing pure tone, so neural responses to pure tone hold promise for predicting the auditory sensitivity of ASD and targeted treatment in children with ASD.

1 Status of Sensory Profile Score among Children with Autism in Selected Centers of Dhaka City

Authors: Sk. Moniruzzaman

Abstract:

Autism is a neurobiological disorder that affects physical, social, and language skills of a person. A child with autism feels difficulty for processing, integrating and responding to sensory stimuli. As Autism is a worldwide burning issue, it becomes highly prioritized and important service provision in Bangladesh. The sensory deficit does not only hamper the normal development of a child, it also hampers the learning process and functional independence. The purpose of this study was to find out the prevalence of sensory dysfunction among children with autism and recognize common pattern of the sensory dysfunction. A cross-sectional survey study design was chosen to carry out this research work. This study enrolled eighty children with autism and their parents by using systematic sampling method. In this study, data were collected through the Short Sensory Profile (SSP) assessment tool which consists of 38-items in the questionnaire and graduate Occupational Therapists were directly involved during interviewing with parents as well as observed child responses to sensory related activities of those children with autism from four selected autism centers in Dhaka, Bangladesh. All item analysis were conducted to identify items yielding or resulting in the highest reported sensory processing dysfunction among those children through using SSP and Statistical Package for Social Science (SPSS) version 21.0 for data analysis. This study revealed that almost 78.25% of children with autism had significantly sensory processing dysfunction based on their sensory response with relevant activities. Under-responsive sensory seeking and auditory filtering was a least common problem among them. On the other hand, most of them 95% were represented that they had definite to probable difference in sensory processing including under-response or sensory seeking, auditory filtering and tactile sensitivity. Besides, the result also showed that the definite difference of sensory processing among 64 children within 100%; it means those children with autism suffered by the sensory difficulties and thus it drew a great impact on the children’s Daily Living Activities (ADLs) as well as social interaction with others. Almost 95% of children with autism have required intervention to overcome or normalize the problem. The result made insight regarding types of sensory processing dysfunction to consider during diagnosis and ascertaining the treatment. So, early sensory problem identification is very important and thus will help to provide appropriate sensory input to minimize the maladaptive behavior and enhance to reach the normal range of adaptive behavior.
