Synchrony is an essential component of interactive exchanges. In mother-infant interaction, synchrony underlies reciprocity and emotive regulation. A severe lack of synchrony is indeed a core issue within the communication and interaction deficit that characterizes autism spectrum disorders (ASD) in accordance with the DSM-5 classification. Based on emerging evidence that music therapy can improve the communication and regulation ability in children with ASD, we aim to verify quantitatively whether: 1) children with ASD improve synchrony with their therapist during music therapy sessions, and 2) this ability persists in different structured contexts.participants and procedure
resultsDuring the IMT cycle, the amount of synchronic activity increases, with a significant difference from Session 1 to Session 20 in behavioral synchrony and emotional attunement. Also, the increase of synchrony is confirmed at the end of the therapy cycle as measured by an interactive ADOS section.
conclusionsSynchrony is an effective indicator of efficacy for music therapy in children with ASD, in particular to evaluate the expansion of positive emotive exchanges.
health psychology report · volume 5(2), 7 original article background Infant research literature has described for a long time the main aspects of parentese (motherese and fatherese) referring to musicality and specifically to musical language. It is believed that there is a deep analogy between the vital affects experienced by the child during interaction with the parent and the type of parentese that is a direct representation of them. Disruption of parentese has been described in early autism. The aim of this paper was to achieve a better understanding of this disruptive process.
participants and procedureSequences of parent-infant interaction extracted from one home movie of a child later diagnosed with autism were analyzed in a micro-musical way in order to create a musical score that allows the description of parent-infant interaction in a new way (considering form, pulse, rhythm, melody, timbre and silence).
resultsMusical microanalysis is able to highlight features not brought out by other kinds of analysis. The first fragment is dominated by the anxiety of the mother, who attempts to stimulate the unresponsive infant. In the second fragment there is a change in musicality parallel to changes in the relationship: the mother participates in and coordinates the infant's experience through rhythm, prosody and musical dynamics. This change persists in the third fragment.
conclusionsMusical transcription of parent-infant interactions has allowed us to highlight changes occurring in a short time during early interactions and to get a closer view of the disruptive process created by autism. This kind of research represents a potential shift in autism research, by focusing on dynamic parent-infant interactions instead of single behaviors of the child or of the parent. The usefulness of Stern's concept of intersubjective communion is discussed.
