Multisensorial Information's Treatment in Autism Spectrum Disorder

Exploring Social Cognition in Autism Spectrum Disorder With Long Time Memory Task. Controlled Study on 8-13 Years Childs

Introduction: Autism spectrum disorder is characterized by deficits in three functional domains: language and communication, social reciprocity, and the presence of restricted interests/repetitive behaviors. There's also deficits in social cognition. When having a face-to-face conversation, a listener not only hears what a speaker is saying, but also sees the articulatory gestures that accompany those sounds. Speech signals needs then a multisensory processing. Impairments in multisensory perceptual binding may be particularly relevant in ASD, given that hallmark features of the disorder include difficulties in speech, communication, and social interactions. Objectives: The investigator suggest that atypical multisensory processing in ASD may have an impact on speech perception and social processing. Aims: Methods: This pilot study measures free recall scores in 3 lists of words presentation after 30 minutes. In the first condition (CI) words are only listening. In the second condition (CII) words are associated with a picture of a mans face. In the third condition (CIII) words are associated with a video of a man speaking. Three lists are homogeneous form words characteristics (lexical frequency, emotional valence norm, imageability). Participants were 7- to 13-year-olds typically developing children (TD) (N = 19) and ASD children (N = 19). The investigator would create some new tools for exploring the treatment of a social information. These tools should be the closest of a ecological social interaction.

Comparison between the group autistic and the group witness of the difference enter the rate of reminder(abseiling) in 30 minutes of the words proposed in video and audio sequences.
