Minimally speaking autism — a historically understudied population
INSAR researchers including Connie Kasari, Helen Tager-Flusberg, and Rebecca Landa have spent years naming what families have long known: minimally verbal autistic people have been left out of most autism research.
What INSAR included
INSAR sessions on minimally speaking autistic people consistently describe a population with uneven expressive abilities, significant communication barriers, and far less research evidence than higher-speaking groups receive.
The supportive research
Kasari, Brady, Lord, and Tager-Flusberg (2013) explain that assessing minimally verbal autistic children is genuinely complex and requires careful consideration of communication, cognition, behavior, and AAC use. Tager-Flusberg and Kasari (2013) describe minimally verbal autistic children outright as a neglected group in autism research.

What parents need to know
Limited speech does not automatically mean limited understanding. The scarcity of large-scale research should not be used to dismiss the growing evidence about the role of neuromotor and sensory challenges in communication. As the field learns more, it becomes increasingly clear that text-based communication approaches addressing the motor barrier deserve deeper study — not dismissal.
If you remember one thing
"Not yet well-studied" is not the same as "not real." For this population, absence of evidence has too often been mistaken for evidence of absence.
