Brief Report: Biological Sound Processing in Children with Autistic Spectrum Disorder

Abstract: There is debate whether social impairments in autism spectrum disorder (ASD) are truly domain-specific, or if they reflect generalized deficits in lower-level cognitive processes. To solve this issue, we used auditory-evoked EEG responses to assess novelty detection (MMN component) and involuntary attentional orientation (P3 component) induced by socially-relevant, human-produced, biological sounds and acoustically-matched control stimuli in children with ASD and controls. Results show that early sensory and n… Show more

“…For example, in post-traumatic stress disorder (PTSD) specific acoustic-limbic circuits may become overly interactive (Schechter et al, 2012; Suo et al, 2015). Conversely, in conditions such as autism spectrum disorder (ASD) there may be a relative lack of acoustic-limbic interconnections that may lead to inappropriate (or a lack of) responses to threat or social/emotional sounds (Tecchio et al, 2003; Baranek et al, 2007; Linke et al, 2017; Lortie et al, 2017). The proposed model may provide a framework for understanding how learned acoustic signals affect, and are affected by, interactions with the limbic system, thereby leading to evidence-based research on targeted intervention for clinicians.…”

“…Quanto aos aspectos metodológicos, no que tange ao número de participantes dos estudos, observou-se o mínimo de 10 (29,36) e o máximo de 30 (36) indivíduos com TEA, sendo que as idades variaram de 4 (25,31,34) a 20 (4) anos; sendo assim, pôde-se observar que alguns estudos avaliaram uma ampla faixa etária (crianças e adolescentes). Quanto ao perfil da população que compôs os grupos de indivíduos com TEA encontrado nos estudos, observou-se que todos os estudos tiveram a maioria dos integrantes do sexo masculino.…”

“…Ainda no que tange aos aspectos metodológicos, observouse que a maioria dos estudos foi realizado com estímulo nãoverbal (4,24,25,(27)(28)(29)(30)(31)(32)(33) . Um estudo analisado na presente revisão utilizou apenas o estímulo verbal (34) , três estudos utilizaram ambos os estímulos (23,34,35) e ainda um estudo utilizou estímulos de sons biológicos (estalo de dedo e sucção de boca) (36) (Quadro 2).
