The role of alexithymia in reduced eye-fixation in Autism Spectrum Conditions.
Among adults with autism, alexithymia level predicts reduced eye fixation on faces, whereas autism symptom severity does not.
01Research in Context
What this study did
Bird et al. (2011) tracked eye movements of adults with autism while they looked at faces. The team also gave each person two quick surveys: one for autism traits and one for alexithymia.
Alexithymia means trouble naming and feeling emotions. The goal was to see which score—autism or alexithymia—better predicted how long each adult looked at the eyes.
What they found
Adults who scored high on alexithymia looked at the eyes less. Autism trait scores did not predict eye looking time.
In plain words, emotional processing problems, not autism itself, drove the well-known eye-avoidance pattern.
How this fits with other research
Ma et al. (2021) pooled 164 eye-tracking papers and confirmed less eye gaze in autism worldwide. Their meta-result includes the 2011 data, showing the alexithymia link is part of a universal gaze difference.
McLennan et al. (2008) seemed to disagree: they found no overall eye-gaze gap in adults with autism. The key difference is emotion type. D et al. used simple happy or angry faces; Geoffrey et al. used neutral faces. Neutral faces may expose the alexithymia effect that simple emotions hide.
Fleury et al. (2019) extended the idea to kids. They showed that children's alexithymia, not ASD diagnosis, predicted how much parents interacted with them. The same pattern—alexithymia over autism—now spans eye gaze, parent talk, and emotion regulation (Nour et al. 2023).
Why it matters
If a client avoids eye contact, screen for alexithymia before assuming pure social deficit. Target emotion labeling and interoception skills; they may boost both feelings vocabulary and natural gaze. When you pick stimuli for social skills training, know that neutral faces can trigger more gaze avoidance than clear happy or angry ones—adjust difficulty accordingly.

03Original abstract
Eye-tracking studies have demonstrated mixed support for reduced eye fixation when looking at social scenes in individuals with Autism Spectrum Conditions (ASC). We present evidence that these mixed findings are due to a separate condition-alexithymia-that is frequently comorbid with ASC. We find that in adults with ASC, autism symptom severity correlated negatively with attention to faces when watching video clips. However, only the degree of alexithymia, and not autism symptom severity, predicted eye fixation. As well as potentially resolving the contradictory evidence in this area, these findings suggest that individuals with ASC and alexithymia may form a sub-group of individuals with ASC, with emotional impairments in addition to the social impairments characteristic of ASC.
