Gender in Voice Perception in Autism / Wouter B. GROEN in Journal of Autism and Developmental Disorders, 38-10 (November 2008)

Although the cortical processing of voice is abnormal in HFA, it is unclear whether this gives rise to impairments in the perception of voice gender. About 20 children with HFA and 20 matched controls were presented with voice fragments that were parametrically morphed in gender. No differences were found in the perception of gender between the two groups of participants, but response times differed significantly. The results suggest that the perception of voice gender is not impaired in HFA, which is consistent with behavioral findings of an unimpaired voice-based identification of age and identity by individuals with autism. The differences in response times suggest that individuals with HFA use different perceptual approaches from those used by typically developing individuals.

Intact Spectral but Abnormal Temporal Processing of Auditory Stimuli in Autism / Wouter B. GROEN in Journal of Autism and Developmental Disorders, 39-5 (May 2009)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-5 (May 2009) . - p.742-750 Titre : Intact Spectral but Abnormal Temporal Processing of Auditory Stimuli in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Wouter B. GROEN, Auteur ; Sophie H. N. SWINKELS, Auteur ; Rutger Jan VAN DER GAAG, Auteur ; Jan K. BUITELAAR, Auteur ; Linda VAN ORSOUW, Auteur ; Marcel ZWIERS, Auteur ; Niels ter HUURNE, Auteur Année de publication : 2009 Article en page(s) : p.742-750 Langues : Anglais (eng) Mots-clés : Autism Connectivity Auditory Perception Speech-in-noise Index. décimale : PER Périodiques Résumé : The perceptual pattern in autism has been related to either a specific localized processing deficit or a pathway-independent, complexity-specific anomaly. We examined auditory perception in autism using an auditory disembedding task that required spectral and temporal integration. 23 children with high-functioning-autism and 23 matched controls participated. Participants were presented with two-syllable words embedded in various auditory backgrounds (pink noise, moving ripple, amplitude-modulated pink noise, amplitude-modulated moving ripple) to assess speech-in-noise-reception thresholds. The gain in signal perception of pink noise with temporal dips relative to pink noise without temporal dips was smaller in children with autism (p = 0.008). Thus, the autism group was less able to integrate auditory information present in temporal dips in background sound, supporting the complexity-specific perceptual account.
