Autism, music and Alexithymia: A musical intervention to enhance emotion recognition in adolescents with ASD.
Five short music talks gave autistic teens a small voice-emotion boost, especially older kids with lower language.
01Research in Context
What this study did
Redondo Pedregal et al. (2021) ran five 30-minute music groups for 12 teens with autism.
Each session played short instrumental pieces. The group talked about how the music felt.
Kids guessed emotions in voices before and after the short program.
What they found
After the five chats, teens scored a little better on voice-emotion tests.
Older kids with lower language gained the most.
Body-awareness also crept up, but there was no control group.
How this fits with other research
Gilmore et al. (2022) pooled 16 stricter trials of teen social-skills groups. They found solid gains, showing music chats are only one flavor.
Lopata et al. (2025) tracked younger kids for years and proved emotion lessons can stick. Their longer view hints these teen gains might fade without boosters.
Anthony et al. (2020) saw that strong verbal skills help emotion work. Celia’s opposite pattern—lower language kids gaining more—may come from music’s non-verbal hook.
Why it matters
If you run teen groups, try a quick music warm-up. Pick short songs, pause, ask “happy or sad?” five times. Track voice-emotion probes weekly. It costs nothing, and older kids with less language may perk up first.

03Original abstract
BACKGROUND: Difficulties identifying and describing emotions in Autism Spectrum Disorder (ASD) have been linked with an increased prevalence of Type 2 Alexithymia. Alexithymia is associated with difficulties in interpreting and verbally labelling physiological arousal. Children and adults with ASD show typical patterns of physiological arousal to music and can attribute verbal labels to musical emotions. AIM: This pilot study aimed to develop a music-based intervention to improve facial and vocal emotion recognition (ER) and Alexithymia in adolescents with ASD. METHODS AND PROCEDURES: Adolescents with ASD completed 5 music sessions and pre and post-tests of Alexithymia, ER and language. Each intervention began with a researcher-led group analysis of the emotions expressed in a series of musical excerpts, followed by a group-led discussion of the participants' experiences of these emotions and the ways they may be communicated. Finally, the likely causes and outward expression of these emotions were discussed. OUTCOME AND RESULTS: Results showed that at pre-test, chronological age (CA) and receptive vocabulary were significantly associated with recognition of facial and verbal emotions and Not hiding emotions. At post-test, older children showed a greater increase in recognition of voices and in emotional bodily awareness. Correlations suggested a trend towards increased ER in voices and faces in children with lower language scores. CONCLUSIONS AND IMPLICATIONS: Music-based interventions may enhance ER in adolescents with ASD and Alexithymia. Limitations and recommendations for future investigations are discussed.
