Minimally verbal school-aged children with autism spectrum disorder: the neglected end of the spectrum.

Tager-Flusberg et al. (2013) · Autism research : official journal of the International Society for Autism Research 2013
★ The Verdict

About 30% of kids with autism stay minimally verbal—swap speech-heavy tests for eye-tracking or AAC and start teaching with tablets or brief ABA to see quick gains.

01Research in Context

01

What this study did

Tager-Flusberg et al. (2013) looked at kids with autism who speak few or no words by school age. They reviewed papers to map why these children are often missed and what tests or teaching might help.

The team focused on children who stay minimally verbal despite years of therapy. They asked how we can better find their strengths and support their communication.

02

What they found

About three in ten children with autism remain mostly non-speaking after early intervention. Standard language tests often fail them because the tasks demand speech or long attention spans.

The review says we should add eye-tracking, brain wave checks, or pictures and devices when speech tests do not work.

03

How this fits with other research

Kasari et al. (2013) wrote a matching review the same year. Both papers say use gentle, child-friendly checks and give the same tips, so the message is steady across sources.

Iacono et al. (2016) later pooled 17 reviews and found AAC tools, like tablets that speak, help these kids ask for things. Koenen et al. (2016) then tested play sessions with such devices and saw more child-initiated talk after six months, proving the idea works in real therapy.

Cariveau et al. (2019) shifted to girls only and used a short ABA program. They showed large gains in just four weeks, hinting that older reviews may under-estimate how fast progress can come when teaching is intense and tailored.

04

Why it matters

If a school-aged child with autism is still mostly quiet, do not keep giving the same speech test. Try eye-tracking games, picture boards, or quick brain response checks to find what they know. Then start AAC, parent coaching, or brief intensive teaching right away. These steps turn the neglected end of the spectrum into an active learner in your session today.

03Original abstract

It is currently estimated that about 30% of children with autism spectrum disorder remain minimally verbal, even after receiving years of interventions and a range of educational opportunities. Very little is known about the individuals at this end of the autism spectrum, in part because this is a highly variable population with no single set of defining characteristics or patterns of skills or deficits, and in part because it is extremely challenging to provide reliable or valid assessments of their developmental functioning. In this paper, we summarize current knowledge based on research including minimally verbal children. We review promising new novel methods for assessing the verbal and nonverbal abilities of minimally verbal school-aged children, including eye-tracking and brain-imaging methods that do not require overt responses. We then review what is known about interventions that may be effective in improving language and communication skills, including discussion of both nonaugmentative and augmentative methods. In the final section of the paper, we discuss the gaps in the literature and needs for future research.
