No Evidence of Emotional Dysregulation or Aversion to Mutual Gaze in Preschoolers with Autism Spectrum Disorder: An Eye-Tracking Pupillometry Study.

The team watched the preschoolers with and without autism. Each child looked at faces on a screen. Sometimes the eyes looked back (mutual gaze). The kids wore eye-tracking goggles. A hidden camera measured pupil size every millisecond.

Pupil growth shows emotional arousal. Bigger pupils mean more excitement or stress. The test lasted only a few minutes. No teaching or rewards were given.

Both groups showed the same pupil change. Eyes made their pupils grow a tiny bit, whether the face looked back or away. Kids with autism did not show extra stress. They looked at the eyes just as long as typical kids.

The data say eye contact is not painful for most preschoolers with autism. Gaze aversion is not built-in.

Kaartinen et al. (2016) seems to disagree. They saw that children with autism who stay tense longer during eye contact have worse social skills. The difference is method: Miia used heart and skin sensors; J et al. used pupils. Heart rate may catch stress that pupils miss.

Zhao et al. (2023) extends the story. In live conversation, Chinese children with autism do look less at mouths and faces. The lab still finds no fear, but real talk changes where kids look.

Root et al. (2017) used the same pupillometry setup. They found odd reflexes to bright light in autism, yet emotions stayed flat. The gear works; the emotion gap stays missing.

Stop assuming eye contact hurts. If a preschool client looks away, check for other reasons: task too hard, boring, or unclear. Use his name or favorite toy first. Teach eye contact as a useful skill, not something to endure. Track progress with quick pupil checks if you have the gear, but trust social gains more than pupil size.
