Expressive Incoherence and Alexithymia in Autism Spectrum Disorder.

The team watched autistic and neurotypical kids during a frustrating game. They coded whether each child’s face matched how they said they felt.

Kids also filled out a short alexithymia scale so the team could see if trouble naming feelings predicted mismatched faces.

Autistic children showed more “expressive incoherence” — their faces did not line up with their words.

Higher alexithymia scores predicted part of this mismatch, even after accounting for autism symptoms.

Griffin et al. (2016) first showed that alexithymia is far more common in autistic kids than in peers. Costa et al. (2017) now links that trait to a visible behavior clinicians can see.

Legiša et al. (2013) also found face-word mismatches in autistic children, but used smell stimuli. The new study shows the same pattern during social frustration, strengthening the idea that the mismatch is stable across tasks.

McCauley et al. (2018) looked under the hood and found alexithymia weakens the tie between body arousal and felt emotion. Together the three papers build a chain: poor inner sensing → trouble labeling → face that does not match words.

When an autistic client says “I’m fine” yet looks furious, the gap is real and may stem from alexithymia, not defiance. Screen for emotion-word skills, teach feeling labels, and rely less on facial cues alone when you check understanding.
