Public ISBD [article]  inMolecular Autism > (March 2014) . - p.1-8 Titre : Hyperreactivity to weak acoustic stimuli and prolonged acoustic startle latency in children with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Hidetoshi TAKAHASHI, Auteur ; Takayuki NAKAHACHI, Auteur ; Sahoko KOMATSU, Auteur ; Kazuo OGINO, Auteur ; Yukako IIDA, Auteur ; Yoko KAMIO, Auteur Article en page(s) : p.1-8 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : People with autism spectrum disorders (ASD) are known to have enhanced auditory perception, however, acoustic startle response to weak stimuli has not been well documented in this population. The objectives of this study are to evaluate the basic profile of acoustic startle response, including peak startle latency and startle magnitude to weaker stimuli, in children with ASD and typical development (TD), and to evaluate their relationship to ASD characteristics.

Relationship of the Acoustic Startle Response and Its Modulation to Emotional and Behavioral Problems in Typical Development Children and Those with Autism Spectrum Disorders / Hidetoshi TAKAHASHI in Journal of Autism and Developmental Disorders, 46-2 (February 2016)

We investigated acoustic startle response (ASR) modulations in 17 children with ASD and 27 with typical development (TD). Compared to TD, children with ASD had larger ASR magnitude to weak stimuli and more prolonged peak startle-latency. We could not find significant difference of prepulse inhibition (PPI) or habituation in ASD children compared to TD. However, habituation and PPI at 70-dB prepulses were negatively related to several subscales of Social Responsiveness Scale and the Strengths and Difficulties Questionnaire, when considering all children. Comprehensive investigation of ASR and its modulation might increase understanding of the neurophysiological impairments underlying ASD and other mental health problems in children.
