Speech Pauses in Conversation: A Neurological Look at Autistic Traits

For many of us, maintaining a flowing conversation is a complex activity in which we perceive and interpret many social cues, often unconsciously. One of these important cues is conversational turn-taking - those short pauses between one person finishing speaking and another person beginning. Research indicates that autistic people may process pragmatic language cues differently.

A new study published in Psychophysiology in July 2026 sought to better understand how conversational turn-taking manifests at the neurological level in people with autistic traits. The researchers examined 63 adults selected based on a range of autistic traits. They used conversation-based stimuli that included speech pauses of varying lengths and tested two response pathways:

  • Brain response: By measuring event-related potentials (ERPs), specifically the P3 response, which indicates stimulus salience.
  • Behavioral response: Subjective ratings of conversation quality.

What did the study find?

The main finding of the study indicates that among participants who exhibited a higher level of autistic traits, prolonged speech pauses were perceived as less salient. This was reflected in a reduced P3 response in their brains. In other words, their brains reacted with less intensity to long pauses in conversation, which may indicate a difference in how these cues are processed.

It is important to note that the study found that general monitoring of speech pauses in conversation, as well as subjective ratings of conversation quality, were not related to the participants' autistic traits. This finding suggests that the difference may be specific to the pragmatic inference from these pauses, rather than to the general perception of conversation or the ability to identify pauses.

Implications of the findings for autistic adults

These findings provide an initial glimpse into the neurological mechanisms that may influence pragmatic communication in people with autistic traits. A deeper understanding of how the brain processes conversational turn-taking can help the research community develop more targeted tools and support, which will help autistic people navigate various social situations better.

It should be remembered that these are preliminary findings, and further research is needed to validate and expand these understandings. However, they lay an important foundation for continued investigation into the relationship between neurological responses and the pragmatic aspects of communication in autistic people.
