Emotional resonance deficits in autistic children.
Autistic kids imitate fine, but emotional faces do not boost their performance like they do for typical peers.
01Research in Context
What this study did
Researchers asked 24 high-functioning autistic kids and 24 typical kids to copy hand gestures. First they saw a face with no emotion. Then they saw happy or angry faces right before the gesture.
Each child did 60 trials while the team filmed and scored how fast and accurately they copied the move.
What they found
When the face was neutral, both groups copied the gesture the same. But when happy or angry faces showed up, only the typical kids moved faster and more precisely. The autistic kids kept the same speed and accuracy.
The emotional faces gave typical children a quick social boost. That boost never came for the autistic children.
How this fits with other research
Schulte-Rüther et al. (2017) saw the same pattern in the face. Autistic kids pulled automatic facial mimicry just like peers, but the mimicry did not link to later empathy scores. Motor mirror wires work; the social volume knob is off.
Begeer et al. (2006) helps explain why. When they told autistic kids to decide which face looked friendlier, the kids studied emotions as long as controls. The problem is not seeing emotion; it is using emotion without being told.
Twito et al. (2024) carried the story into adulthood. Autistic adults could learn the first 'average' facial emotion but could not update it when the emotion changed. The rigidity found in Alessandro's child imitation shows up again in adult face learning.
Why it matters
Your client can copy you, but happy or angry faces will not give that free social push. Do not wait for emotional cues to strengthen responding. Instead, give clear instructions, extra trials, or external rewards. When you want faster or cleaner responses, state the goal plainly or add a preferred item. Do not assume a smile will prime the skill.

03Original abstract
According to some theories imitation, defined as an action resonance mechanism, is deficient in autism. In contrast, other theories (e.g., the "top down control of imitation" hypothesis) state that the problem is not in imitation per se but in the way social cues modulate imitative responses. In this study, 15 high-functioning children with autism and 15 matched controls were tested for their ability to imitate finger movements preceded by neutral and emotional facial expressions (primes) in a stimulus-response compatibility task. Hand movements performed after neutral expressions did not differ between the two groups (i.e., they both showed a normal imitative tendency). However, hand movements performed after emotional expressions significantly differed between the two populations, with controls, but not autistic spectrum disorder (ASD), showing enhanced imitation in the emotional condition. This study supports the view that, in ASD, imitation abilities are spared but they are not modulated according to the emotional and social context.
