Cognitive and adaptive correlates of an ADOS-derived joint attention composite.
Language skill, not joint attention itself, drives later adaptive gains in kids with ASD.
01Research in Context
What this study did
The team looked at the kids with autism. They pulled joint-attention scores from the ADOS and linked them to IQ and daily-living skills.
They used stats to see if language skill was the bridge between joint attention and real-world behavior.
What they found
Kids who showed more joint attention also had higher IQ and better daily skills.
But when the kids had strong verbal IQ, joint attention no longer predicted daily skills. Language was doing the heavy lifting.
How this fits with other research
Fujiura et al. (2018) tracked the same kids over years and saw daily skills stop rising in the teen years. Johnson’s finding hints that boosting language earlier might keep those gains going.
Kourassanis-Velasquez et al. (2019) and Pérez-Fuster et al. (2022) proved you can raise joint-attention scores with peer training or AR games. Johnson shows the next step: pair those games with language-rich prompts.
Liu et al. (2021) used eye-tracking to show autistic kids shift gaze slower during joint attention. Johnson’s work says the real payoff comes after the gaze shift—when the child uses words to comment.
Why it matters
If you run joint-attention drills, weave in strong language targets. Ask the child to name, request, or comment every time they follow your gaze. The language piece may be what turns a social moment into lasting daily-life skill.

03Original abstract
Joint attention skills have been shown to predict language outcomes in children with autism spectrum disorder (ASD). Less is known about the relationship between joint attention (JA) abilities in children with ASD and cognitive and adaptive abilities. In the current study, a subset of items from the Autism Diagnostic Observation Schedule (ADOS), designed to quantify JA abilities, were used to investigate social attention among an unusually large cross-sectional sample of children with ASD (n = 1061). An examination of the association between JA and a range of functional correlates (cognitive and adaptive) revealed JA was significantly related to verbal (VIQ) and non-verbal (NVIQ) cognitive ability as well as all domains of adaptive functioning (socialization, communication, and daily living skills). Additional analyses examined the degree to which the relation between adaptive abilities (socialization, communication, and daily living skills) and JA was maintained after taking into account the potentially mediating role of verbal and nonverbal cognitive ability. Results revealed that VIQ fully mediated the relation between JA and adaptive functioning, whereas the relation between these adaptive variables and JA was only partially mediated by NVIQ. Moderation analyses were also conducted to examine how verbal and non-verbal cognitive ability and gender impacted the relation between JA and adaptive functioning. In line with research showing a relation between language and JA, this indicates that while JA is significantly related to functional outcomes, this appears to be mediated specifically through a verbal cognitive pathway.
