Acting on observed social exclusion and pro-social behaviour in autism spectrum disorder.

Silva et al. (2020) · Autism : the international journal of research and practice 2020
★ The Verdict

Autistic people are less likely to offer help after seeing exclusion, so you must teach the exact words and actions to use.

✓ Read this if BCBAs running social-skills groups or inclusion programs in schools and clinics.
✗ Skip if Clinicians focused only on non-social repertoires like self-care or academics.

01Research in Context

01

What this study did

Silva et al. (2020) watched autistic and neurotypical adults after they saw someone being left out.

The team used a lab game where one player was excluded. They then counted how often each observer stepped in to help.

No one got training or prompts; the study looked only at natural, spontaneous reactions.

02

What they found

Autistic viewers offered less help and showed smaller mood changes after seeing exclusion.

Neurotypical observers more often handed over points or spoke up for the excluded player.

The gap stayed even when everyone clearly noticed the exclusion scene.

03

How this fits with other research

Amaral et al. (2019) saw the same pattern in younger kids: autistic pre-teens helped less, and low motivation was not the cause.

Van Hoorn et al. (2017) seems to disagree—they found that autistic teens gave more tokens after peer feedback. The key difference is outside cues: the 2020 study had none, while the 2017 study added clear peer comments.

Santos et al. (2012) helps explain why: autistic adults did not automatically look at negative social scenes, so they may need extra signals to notice and act.

04

Why it matters

If your client sees bullying or left-out peers, do not assume they will naturally step in. Add explicit teaching. Model what to say, role-play handing over a toy or inviting the peer, and give praise for these scripted helping acts. Over time, fade the prompts so the kind behavior stays.

03Original abstract

Humans are commonly motivated towards cooperation and prosociality. In this study, we examined this motivational predisposition in autistic individuals. Using an adaptation of the Cyberball paradigm, we investigated subsequent pro-social behaviour after witnessing social exclusion. Participants witnessed and played a series of Cyberball games, rated their affective state and valued emotional faces with respect to their approachability. Results showed that participants from both groups were aware of the social exclusion. However, while neurotypically developing participants engaged in pro-social behaviour in reaction to the exclusion, autistic participants showed less alterations, in terms of either behaviour or affective state. The current findings suggest a distinct motivational drive and processing of social reward stimuli in autism, which may result in behavioural responses divergent from typical development when engaging in the social world.
