Neural Evidence for Speech Processing Deficits During a Cocktail Party Scenario in Minimally and Low Verbal Adolescents and Young Adults with Autism.
Minimally verbal teens with autism show absent early brain responses to their own name in noisy rooms—consider auditory filtering supports before assuming non-compliance.
01Research in Context
What this study did
Schwartz et al. (2020) wired minimally verbal teens and young adults with autism to EEG caps.
They played a recording of many people talking at once—like a loud party.
Sometimes the teen’s own name was hidden in the chatter.
The team asked: does the brain notice the name in the noise?
What they found
The early brain spike that should shout “that’s my name!” never showed up.
Kids who had the weakest brain reaction also had the hardest time tuning voices out.
In short, their auditory filter was broken, not their will to answer.
How this fits with other research
Russo et al. (2009) saw the same weak brain reaction years earlier, but in younger kids and with simpler noise.
Schelinski et al. (2020) later tested verbal adults with autism and still found poor speech-in-noice scores, proving the problem lasts across age and language level.
Chuah et al. (2025) pooled many MMN studies and showed smaller change-detection waves in autistic youth; Sophie’s missing name wave lines up perfectly with that pattern.
Together the papers trace one story: from preschool brain-stem oddities to teen cortical gaps to adult speech struggles.
Why it matters
If a client ignores you in a busy room, don’t assume defiance.
Cut background noise first—close doors, turn off fans, use soft walls.
Try calling the child’s name before giving instructions, and wait for eye contact or a head turn.
These tiny environmental tweaks can spare you hours of “non-compliance” programming.

03Original abstract
As demonstrated by the Cocktail Party Effect, a person's attention is grabbed when they hear their name in a multispeaker setting. However, individuals with autism (ASD) are commonly challenged in multispeaker settings and often do not respond to salient speech, including one's own name (OON). It is unknown whether neural responses during this Cocktail Party scenario differ in those with ASD and whether such differences are associated with expressive language or auditory filtering abilities. We measured neural responses to hearing OON in quiet and multispeaker settings using electroencephalography in 20 minimally or low verbal ASD (ASD-MLV), 27 verbally fluent ASD (ASD-V), and 27 neurotypical (TD) participants, ages 13-22. First, we determined whether TD's neural responses to OON relative to other names could be quantified with early frontal mismatch responses (MMRs) and late, slow shift parietal and frontal responses (LPPs/FNs). Second, we compared the strength of MMRs and LPPs/FNs across the three groups. Third, we tested whether participants with poorer auditory filtering abilities exhibited particularly weak neural responses to OON heard in a multispeaker setting. Our primary finding was that TDs and ASD-Vs, but not ASD-MLVs, had significant MMRs to OON in a multispeaker setting, and strength of LPPs positively correlated with auditory filtering abilities in those with ASD. These findings reveal electrophysiological correlates of auditory filtering disruption within a clinical population that has severe language and communication impairments and offer a novel neuroimaging approach to studying the Cocktail Party effect in neurotypical and clinical populations.

LAY SUMMARY: We found that minimally and low verbal adolescents and young adults with autism exhibit decreased neural responses to one's own name when heard in a multispeaker setting. In addition, decreased strength of neural responses in those with autism correlated with decreased auditory filtering abilities. We propose that these neural deficits may reflect the ineffective processing of salient speech in noisy settings and contribute to language and communication deficits observed in autism.
