Prosody recognition in adults with high-functioning autism spectrum disorders: from psychoacoustics to cognition.
High-functioning adults with autism can hear pitch perfectly yet still misread emotional tone, so teach feelings, not just sounds.
01Research in Context
What this study did
Globerson et al. (2015) tested how well high-functioning adults with autism hear and understand emotional tone of voice.
They compared two groups: adults with autism and neurotypical adults. Everyone did simple pitch-discrimination tasks and harder tasks that asked them to name emotions from voice prosody and from faces.
The goal was to see if good basic hearing protects against prosody problems.
What they found
Adults with autism could hear tiny pitch shifts just as well as controls, yet they still mis-read happy, sad, or angry intonation.
Facial emotion reading was also weaker in the autism group.
In short, sharp ears did not translate into sharp social listening.
How this fits with other research
Schelinski et al. (2020) extends the same line: they showed that pitch skill does not predict how well adults with autism understand speech in noise. Together the papers say pitch training alone will not fix real-world listening.
Doi et al. (2013) and O'Connor (2007) echo the target results. They found that autistic adults miss low-intensity angry or sad prosody and struggle to spot when a face and voice do not match.
Tonnsen et al. (2016) seems to contradict the target by calling pitch perception "enhanced" in autism. The clash is only surface-level: enhanced means they detect small pitch changes, not that they grasp emotional meaning. The studies agree that raw pitch skill and social use of pitch are separate.
Why it matters
If you work with verbal adults on the spectrum, do not assume ear-training will teach them to read feelings. Add explicit emotion-labeling drills that pair faces, voices, and context. Check progress with real social clips, not just pitch games.

03Original abstract
Prosody is an important tool of human communication, carrying both affective and pragmatic messages in speech. Prosody recognition relies on processing of acoustic cues, such as the fundamental frequency of the voice signal, and their interpretation according to acquired socioemotional scripts. Individuals with autism spectrum disorders (ASD) show deficiencies in affective prosody recognition. These deficiencies have been mostly associated with general difficulties in emotion recognition. The current study explored an additional association between affective prosody recognition in ASD and auditory perceptual abilities. Twenty high-functioning male adults with ASD and 32 typically developing male adults, matched on age and verbal abilities undertook a battery of auditory tasks. These included affective and pragmatic prosody recognition tasks, two psychoacoustic tasks (pitch direction recognition and pitch discrimination), and a facial emotion recognition task, representing nonvocal emotion recognition. Compared with controls, the ASD group demonstrated poorer performance on both vocal and facial emotion recognition, but not on pragmatic prosody recognition or on any of the psychoacoustic tasks. Both groups showed strong associations between psychoacoustic abilities and prosody recognition, both affective and pragmatic, although these were more pronounced in the ASD group. Facial emotion recognition predicted vocal emotion recognition in the ASD group only. These findings suggest that auditory perceptual abilities, alongside general emotion recognition abilities, play a significant role in affective prosody recognition in ASD.
