Processing of facial expressions of emotions by adults with Down syndrome and moderate intellectual disability.

Carvajal et al. (2012) asked adults with Down syndrome to name happy, sad, angry and fearful faces. They compared scores to adults with similar IQ but no Down syndrome.

The task used still photos. The team also tracked which part of the face each person looked at.

Both groups named the emotions equally well. Overall accuracy was the same.

Adults with Down syndrome made more small mistakes. They also spent more time looking at mouths than eyes.

Root et al. (2017) tested children with Down syndrome using the same faces plus labels. Exaggerated expressions and labels helped every child, but fear stayed harder. The adult null result now extends to kids, with a useful tweak: make faces bigger and say the feeling aloud.

Channell et al. (2014) also found no deficit in youths using dynamic clips and context pictures. Together, three studies say Down syndrome alone does not cause emotion-reading problems.

Repp et al. (1992) is the practical cousin. They taught seven adults with ID to read faces with brief discrete-trial drills. Scores jumped at least 30 % and lasted nine months. Fernando shows you what is; C et al. show you what to do if you need better.

Do not assume poor scores are part of Down syndrome. When an adult misses facial cues, check attention first: are they looking at the mouth only? A quick prompt to “check the eyes” or a brief DTI package from C et al. can fix the issue without lengthy social-skills curricula.
