Calming effects of repetition in music for children with sensory sensitivities: Findings from two experimental studies

Sensory sensitivity and anxiety are often experienced by neurodivergent children. Repetitive physical actions are a common way to self-regulate and reduce anxiety, yet stigma attached to these actions can discourage people with sensory sensitivities from participating in public events such as concerts. Children with sensory sensitivities therefore often miss out on the social benefits of attending live concerts. This paper reports the results of two studies (for each N = 20) investigating whether the predictability/level of internal repetition in classical music can be calming for Australian children aged 5–14 with sensory sensitivities. Study 1 utilized a one-on-one laboratory setting with live piano performance (two low repetition pieces, two high repetition pieces), whereas Study 2 used a group performance setting with a live cello performance (one low repetition piece, one high repetition piece). Proxy measures of anxiety and engagement were completed by parents/carers in both studies, and facial expressions and finger oximeter measures were also captured in Study 1. Across the two studies both music types had a calming effect compared to baseline, with Study 2 also indicating significantly higher interest, involvement, and enjoyment levels for high repetition music. These findings have implications for the use of music for children with sensory sensitivities in arts programming and therapeutic contexts.
