Pitch Processing in Tonal-Language-Speaking Children with Autism: An Event-Related Potential Study / Luodi YU in Journal of Autism and Developmental Disorders, 45-11 (November 2015)
[article]
Titre : Pitch Processing in Tonal-Language-Speaking Children with Autism: An Event-Related Potential Study Type de document : Texte imprimé et/ou numérique Auteurs : Luodi YU, Auteur ; Yuebo FAN, Auteur ; Zhizhou DENG, Auteur ; Dan HUANG, Auteur ; Suiping WANG, Auteur ; Yang ZHANG, Auteur Article en page(s) : p.3656-3667 Langues : Anglais (eng) Mots-clés : Autism Pitch processing Speech perception Language development Event-related potentials (ERPs) Mismatch negativity (MMN) Index. décimale : PER Périodiques Résumé : The present study investigated pitch processing in Mandarin-speaking children with autism using event-related potential measures. Two experiments were designed to test how acoustic, phonetic and semantic properties of the stimuli contributed to the neural responses for pitch change detection and involuntary attentional orienting. In comparison with age-matched (6–12 years) typically developing controls (16 participants in Experiment 1, 18 in Experiment 2), children with autism (18 participants in Experiment 1, 16 in Experiment 2) showed enhanced neural discriminatory sensitivity in the nonspeech conditions but not for speech stimuli. The results indicate domain specificity of enhanced pitch processing in autism, which may interfere with lexical tone acquisition and language development for children who speak a tonal language.

Titre : Auditory conflict processing in ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Rosa VAN MOURIK, Auteur ; Joseph A. SERGEANT, Auteur ; Dirk J. HESLENFELD, Auteur ; Claudia KONIG, Auteur ; Jaap OOSTERLAAN, Auteur Année de publication : 2011 Article en page(s) : p.265-274 Langues : Anglais (eng) Mots-clés : ADHD interference conflict auditory Stroop event-related potentials (ERPs) Index. décimale : PER Périodiques Résumé : Background: Impaired cognitive control has been implicated as an important developmental pathway to attention deficit/hyperactivity disorder (ADHD). Cognitive control is crucial to suppress interference resulting from conflicting information and can be measured by Stroop-like tasks. This study was conducted to gain insight into conflict processing in children with ADHD.
Methods: Event-related potentials (ERPs) were recorded in an auditory Stroop task. Twenty-four children with ADHD were compared with 24 control children (aged 8–12 years).
Results: No deficit in interference control was found on the auditory Stroop task in children with ADHD. Children with ADHD responded more slowly, less accurately and more variably compared to controls. No differences between the groups occurred in the early conflict-related ERPs. However, the difference between the congruent and the incongruent condition in the 450–550 ms time window was absent in the ADHD group compared to controls. In addition, the conflict sustained potential was found frontally in the ADHD group but parietally in the control group.
Conclusions: These ERP findings suggest that children with ADHD evaluate conflict to a lesser extent and differ in the way their brains select appropriate responses during conflict compared with controls.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02339.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=118

Titre : Defining clusters of young autistic and typically developing children based on loudness-dependent auditory electrophysiological responses Type de document : Texte imprimé et/ou numérique Auteurs : Patrick DWYER, Auteur ; Xiaodong WANG, Auteur ; Rosanna DE MEO-MONTEIL, Auteur ; Fushing HSIEH, Auteur ; Clifford D. SARON, Auteur ; Susan M. RIVERA, Auteur Article en page(s) : 48 p. Langues : Anglais (eng) Mots-clés : Autism Event-related potentials (ERPs) Heterogeneity Hierarchical clustering Sensory processing Subgroups study. Index. décimale : PER Périodiques Résumé : BACKGROUND: Autistic individuals exhibit atypical patterns of sensory processing that are known to be related to quality of life, but which are also highly heterogeneous. Previous investigations of this heterogeneity have ordinarily used questionnaires and have rarely investigated sensory processing in typical development (TD) alongside autism spectrum development (ASD). METHODS: The present study used hierarchical clustering in a large sample to identify subgroups of young autistic and typically developing children based on the normalized global field power (GFP) of their event-related potentials (ERPs) to auditory stimuli of four different loudness intensities (50, 60, 70, 80?dB SPL): that is, based on an index of the relative strengths of their neural responses across these loudness conditions. RESULTS: Four clusters of participants were defined. Normalized GFP responses to sounds of different intensities differed strongly across clusters. There was considerable overlap in cluster assignments of autistic and typically developing participants, but autistic participants were more likely to display a pattern of relatively linear increases in response strength accompanied by a disproportionately strong response to 70?dB stimuli. Autistic participants displaying this pattern trended towards obtaining higher scores on assessments of cognitive abilities. There was also a trend for typically developing participants to disproportionately fall into a cluster characterized by disproportionately/nonlinearly strong 60?dB responses. Greater auditory distractibility was reported among autistic participants in a cluster characterized by disproportionately strong responses to the loudest (80?dB) sounds, and furthermore, relatively strong responses to loud sounds were correlated with auditory distractibility. This appears to provide evidence of coinciding behavioral and neural sensory atypicalities. LIMITATIONS: Replication may be needed to verify exploratory results. This analysis does not address variability related to classical ERP latencies and topographies. The sensory questionnaire employed was not specifically designed for use in autism. Hearing acuity was not measured. Variability in sensory responses unrelated to loudness is not addressed, leaving room for additional research. CONCLUSIONS: Taken together, these data demonstrate the broader benefits of using electrophysiology to explore individual differences. They illuminate different neural response patterns and suggest relationships between sensory neural responses and sensory behaviors, cognitive abilities, and autism diagnostic status.

Reading performance is similar for the two groups in both languages. While reading Mandarin Chinese, the control group showed a left-hemispheric specialization within the 400–600 ms interval in delta synchronization. However, delta synchronizations were widely distributed in all scalp regions and lasted longer than 600 ms in the AS group. One possible interpretation of our data is the hypothesis that the AS group has more difficulty in brain organization of semantic and syntactic processes than the control group when reading their native language, because Chinese syntactic structure requires more work to be done by the perceiver. Nevertheless, other brain mechanisms (e.g., top-down regulation), can partially compensate for this difficulty, allowing AS subjects to attain the same level of response activity as the controls.
