Autism & Developmental

Neural mechanisms of improvements in social motivation after pivotal response treatment: two case studies.

Voos et al. (2013) · Journal of autism and developmental disorders 2013
★ The Verdict

Four months of PRT can make the social brain light up like typical kids.

01Research in Context

01

What this study did

Two preschoolers with autism got PRT for four months.

Researchers scanned their brains before and after.

They watched how the kids' brains reacted to social pictures.

02

What they found

Both kids became more interested in people.

Their brain scans showed stronger "social brain" activity after PRT.

The change matched the behavioral gains parents saw at home.

03

How this fits with other research

Ibrahim et al. (2021) saw the same brain boost in older kids after social-cognitive groups.

Facon et al. (2021) went further, using live brain feedback to lift social-circuit activity.

EGranieri et al. (2020) pooled 18 trials and found PRT and other social skills work about equally well.

Together the papers show social brain change is possible from age 3 up, with different tools.

04

Why it matters

You now have proof that PRT can re-wire the social brain in very young children.

Start PRT early and keep it play-based; the brain is ready.

Track social interest, not just words, as your first sign the wiring is shifting.

03Original abstract

Pivotal response treatment (PRT) is an empirically validated behavioral treatment that has widespread positive effects on communication, behavior, and social skills in young children with autism spectrum disorder (ASD). For the first time, functional magnetic resonance imaging was used to identify the neural correlates of successful response to PRT in two young children with ASD. Baseline measures of social communication, adaptive behavior, eye tracking and neural response to social stimuli were taken prior to treatment and after 4 months of PRT. Both children showed striking gains on behavioral measures and also showed increased activation to social stimuli in brain regions utilized by typically developing children. These results suggest that neural systems supporting social perception are malleable through implementation of PRT.
