Is the linguistic content of speech less salient than its perceptual features in autism?

Järvinen-Pasley et al. (2008) asked whether autistic children tune in to how speech sounds or to what the words mean.

They compared kids with autism to typically developing peers on tasks that pitted sound features against word meaning.

The team used simple listening tests and checked which cue the children trusted more.

Autistic kids did notice speech sounds more strongly than controls, but meaning still ruled their responses.

The linguistic edge was weaker than in controls, yet it was still the main driver.

In short, perceptual salience goes up, yet semantics stay on top.

Ploog et al. (2007) found no sign of poor semantic encoding in autism, matching the current view that meaning is still processed.

Iarocci et al. (2010) extended this by showing autistic kids gain less from lip-reading, pointing to a wider pattern of reduced perceptual help from visual cues.

Ganz et al. (2009) and Finke et al. (2017) both found auditory temporal glitches that could explain why perceptual features feel louder to these children.

Keep teaching content, not just sounds. Autistic learners still lock onto meaning, so use clear, rich language and embed targets in semantically heavy activities. If you add visual or auditory aids, check that they support, not overshadow, the message.
