Gestural communication in children with autism spectrum disorders during mother-child interaction.
Toddlers with autism give fewer and flatter gestures—watch for pointing with eye contact to catch the difference fast.
01Research in Context
What this study did
Researchers watched young learners play with their moms for 10 minutes. They counted every gesture the child made: pointing, showing, waving, reaching.
Kids had autism, Down syndrome, or were typically developing. Coders wrote down what each gesture looked like and why the child seemed to use it.
What they found
Toddlers with autism used half as many gestures as the other groups. Their gestures were also simpler—more reaching, less pointing with eye contact.
Down syndrome and typical toddlers mixed sounds and gestures. Autism group used mostly one or the other, not both together.
How this fits with other research
Greenlee et al. (2024) extends this work. They let a computer track the same kind of play. Machine data show kids who move faster and closer to mom later score high on autism tests. Manual gesture counts and motion sensors tell the same story in different languages.
Gabriels et al. (2001) came first. Their parent checklist flags autism risk at 18 months. Marilina’s fine-grained gesture coding gives you the ‘why’ behind those red-flag items—fewer pointing and showing acts.
Fullana et al. (2007) looks like a contradiction: school-age kids with Down syndrome out-engage kids with autism in class. But the toddlers in Marilina’s study already showed the same social gap. The pattern starts early and lasts.
Why it matters
During intake, pull out a simple toy and watch for three things: Does the child point to show you something? Do they look back at your eyes after pointing? Do they combine a word or sound with the point? Missing two of these for five minutes is a quick early warning you can note right away.

03Original abstract
Children with autism spectrum disorders display atypical development of gesture production, and gesture impairment is one of the determining factors of autism spectrum disorder diagnosis. Despite the obvious importance of this issue for children with autism spectrum disorder, the literature on gestures in autism is scarce and contradictory. The purpose of this study was to analyze gestural communication in children with autism spectrum disorder during spontaneous mother-child interaction. Participants were children with autism spectrum disorder (n = 20), Down's syndrome (n = 20), and typical development (n = 20) and their mothers. Children's mean developmental age was 24.16 months (standard deviation = 1.45 months) and did not differ across the groups. Gestural communication was analyzed with a specific coding scheme allowing a quantitative and qualitative analysis of gestural production. Results showed the following: (a) differences between autism spectrum disorder, typical development, and Down's syndrome groups in the total number of gestures produced; (b) differences between the three groups in the distribution of gesture types; and (c) specific correlations between gestural production, cognitive development, and autism severity scores. The study of gestures in autism spectrum disorder could help us to identify different phenotypes in autism and could also lead to the development of new therapies.
