Are deficits in the decoding of affective cues and in mentalizing abilities independent?

Adkins et al. (1997) asked if reading faces and reading minds are two separate problems in kids with PDD.

They compared children with PDD, other clinical issues, and typical peers on emotion-recognition and theory-of-mind tasks.

The design was quasi-experimental: same tasks, different groups, no random assignment.

Inside the PDD group, kids who were worse at emotion tasks also tended to be worse at mind-reading tasks.

Yet this link was looser than in typical kids, as if the two skills do not fully team up in PDD.

Thirion-Marissiaux et al. (2008) extend the same question to kids with intellectual disability. They found the tie between emotion and belief skills follows normal timing when kids are matched for developmental age.

Carter Leno et al. (2021) revisit the link with tighter IQ control. Once verbal IQ was held constant, the tie between mind-reading and behavior problems vanished, showing IQ can hide behind apparent social-cognition deficits.

Amorim et al. (2025) cast the widest net, testing autism, ADHD, and OCD. Diagnosis mattered less than everyday social-communication scores, pushing the field past simple autism-vs-typical splits.

If emotion and mind-reading skills are only loosely coupled in PDD, you may need to teach each one separately. Check verbal IQ before labeling a social-cognition score as "low," and track social-communication skills across diagnoses rather than assuming autism is the key flag.
