Neural Processing of Speech Sounds in Autistic Kindergarteners as a Predictor of Reading Outcomes.
A quick kindergarten brain-wave check can warn you which autistic kids are likely to stumble over word recognition later.
01Research in Context
What this study did
Manning et al. (2026) recorded brain waves while autistic and neurotypical kindergarteners listened to speech sounds. They then tracked each child’s reading skills through the end of the year.
The team focused on two early brain peaks, P1 and P2, that show whether the brain notices a sound is new or repeated.
What they found
Kids with autism who had larger P1/P2 ‘old/new’ responses in kindergarten scored better on word recognition nine months later.
The link was small and showed up only for word calling, not for understanding what the words mean.
How this fits with other research
Vanvooren et al. (2017) saw the same pattern in neurotypical kids: better speech-in-noise skills predicted later reading. L et al. extend that idea to autistic children and show brain waves can do the predicting.
Hogg et al. (1995) found smaller early auditory ERPs in autism, which seems opposite. The difference is task: J tested loudness changes; L tested memory for speech sounds. Memory responses can stay strong even when basic loudness responses are weak.
Bhaumik et al. (2009) review argues ERPs should guide early diagnosis. L et al. give a concrete example—use kindergarten speech ERPs to flag reading risk before formal instruction begins.
Why it matters
You now have a five-minute, non-verbal screen that spots autistic kindergarteners who may struggle to read words. Pair it with phonics probes and start targeted literacy routines earlier, instead of waiting for first-grade failure.

03Original abstract
Phonology is an important foundation of reading development; however, little is known about the neural substrates of speech sound processing and reading development in autistic children. We investigated early auditory event-related potentials (ERPs) in response to speech sounds and their association with reading ability (word recognition and reading comprehension). 56 kindergarteners (28 ASD, 28 TD) completed an ERP task using rhyming, bisyllabic pseudowords (/gibu/ and /bidu/) in an old/new design: 50% "old" and 50% "new" stimuli presented following a sensitization block of 100% "old" stimuli. Behavioral measures of reading ability were completed at kindergarten entry and exit. Results from generalized linear mixed models revealed a significant three-way interaction between stimuli ("new" vs. "old"), diagnosis (ASD vs. TD), and reading ability (for word recognition and reading comprehension) for P1 and P2 amplitude. Follow-up analyses revealed that autistic children with lower reading abilities showed greater P1 and P2 amplitudes for "new" vs. "old" stimuli, with effects ranging from marginal to significant (p's 0.04-0.07). Regression analyses revealed that old/new ERP difference scores significantly predicted later word recognition at kindergarten year-end (P1 amplitude: p = .05; P2 amplitude: p = .04), but not reading comprehension, controlling for sex and nonverbal IQ. Autistic children with poorer reading skills, specifically those with weaker word recognition abilities, show neural differences when processing speech sounds compared to autistic peers with greater reading ability and typically developing children. A better understanding of the neural basis of speech sound processing could enhance our insight into the heterogeneity in reading among individuals with ASD and guide future treatment approaches.
