Increased openness to external influences in adolescents with intellectual disability: Insights from an experimental study on social judgments.

Egger et al. (2021) · Research in developmental disabilities 2021
★ The Verdict

Teens with ID are extra open to peer and non-social nudges when judging people, so build in guardrails.

✓ Read this if BCBAs working on social skills or bullying prevention with middle-schoolers who have ID.
✗ Skip if Clinicians serving only autistic clients without ID or adult populations.

01Research in Context

01

What this study did

Ramos-Cabo et al. (2021) asked 48 teens with intellectual disability to judge short social stories. Half the stories had hidden cues that pushed the teens toward harsher or nicer ratings.

The team also tested 48 typical teens of the same age and 48 younger kids without disability. They wanted to see who changed their ratings after the hidden cues.

02

What they found

Teens with ID swung to the extremes. They gave much harsher or much nicer scores right after the hidden cue. Typical teens stayed steady. The ID group acted like children four years younger.

Even non-social cues, such as color borders, swayed their choices.

03

How this fits with other research

Raspail et al. (2025) helps explain why. They show that poor inhibition in mild ID links to mis-reading faces and intent. Weak brakes let outside cues rush in.

Beaurenaut et al. (2024) used a similar lab game with autistic adults and found no extra sway. This flags that the jumpy judgment pattern is tied more to ID than to autism traits.

Honigfeld et al. (2012) and van Rijn et al. (2008) map social deficits in sex-chromosome disorders. Together the four papers sketch a line: when executive skills lag, social cues hijack choices.

04

Why it matters

If you run social-skills groups, expect teens with ID to echo the last thing they hear. Preview tough scenes, teach a stop-and-check routine, and rehearse saying “Is that a fact or just a feeling?” before they post or speak.

03Original abstract

BACKGROUND: Making appropriate social judgments about one's peers helps avoid negative influences from peers, yet the cognitive and adaptive difficulties experienced by adolescents with an intellectual disability (ID) may create challenges in this regard. PROCEDURE: This study used a computer-based task to investigate how adolescents with ID (n = 34, M = 14.89 years, SD = 1.38) and comparison groups of chronological age-matched adolescents without ID (n = 34, M = 14.68, SD = 1.16) and mental age-matched children (n = 34, M = 7.88, SD = .62) make social judgments of photos of adolescents, and the degree to which they are influenced by non-social and social cues in performing this task. RESULTS: Analyses showed adolescents with ID made significantly more polarizing judgments and showed a positivity bias compared to adolescents without ID. This judgment pattern was similar to that of younger mental age-matched children. Adolescents with ID were also significantly more influenced by non-social cues and peer opinions than adolescents from the control group. IMPLICATIONS: The results provide new perspectives for future research and support of adolescents with ID.
