Processing of Spontaneous Emotional Responses in Adolescents and Adults with Autism Spectrum Disorders: Effect of Stimulus Type.
Still photos help autistic adolescents and adults learn simple emotions, but short videos are better for mixed feelings like a sarcastic smile.
01Research in Context
What this study did
Kuhl et al. (2015) showed photos and short videos to autistic and non-autistic teens and adults. The faces showed simple feelings like happy or sad, and also tricky blends like a 'confused smile.'
Each person labeled the emotion while the team tracked their eye gaze. The goal was to see if still pictures or moving clips made emotion reading easier.
What they found
Autistic participants did better with still photos when the emotion was simple. They had more trouble with still photos that showed mixed feelings.
Moving clips helped them spot the mixed emotions. Eye gaze looked about the same between groups; where they looked did not explain the accuracy gaps.
How this fits with other research
Georgopoulos et al. (2022) later tested the same adult group with more tasks and found only tiny accuracy gaps. This extends the 2015 finding: once you add lots of trials and formats, the deficit almost vanishes.
Evers et al. (2015) tested autistic kids with the same photo-vs-video setup and saw a small global lag for moving faces. Together, the two 2015 studies show the age shift: kids struggle with any motion, adults mainly need motion for subtle blends.
Sherwell et al. (2014) asked adults to work backward from a smile to guess what gift had been given. They found a clear deficit for real and fake smiles. The 2015 study refines that result: static photos can work, but only for simple smiles, not the tricky ones.
Why it matters
If you teach social skills to autistic teens or adults, start with still photos for basic feelings. Move to short video clips when you practice mixed emotions like nervous excitement. Do not assume poor eye contact is the culprit; instead, give extra chances to see the emotion in motion.

03Original abstract
Recent research has shown that adults with autism spectrum disorders (ASD) have difficulty interpreting others' emotional responses, in order to work out what actually happened to them. It is unclear what underlies this difficulty; important cues may be missed from fast paced dynamic stimuli, or spontaneous emotional responses may be too complex for those with ASD to successfully recognise. To explore these possibilities, 17 adolescents and adults with ASD and 17 neurotypical controls viewed 21 videos and pictures of peoples' emotional responses to gifts (chocolate, a handmade novelty or Monopoly money), then inferred what gift the person received and the emotion expressed by the person while eye movements were measured. Participants with ASD were significantly more accurate at distinguishing who received a chocolate or homemade gift from static (compared to dynamic) stimuli, but significantly less accurate when inferring who received Monopoly money from static (compared to dynamic) stimuli. Both groups made similar emotion attributions to each gift in both conditions (positive for chocolate, feigned positive for homemade and confused for Monopoly money). Participants with ASD only made marginally significantly fewer fixations to the eyes of the face, and face of the person than typical controls in both conditions. Results suggest adolescents and adults with ASD can distinguish subtle emotion cues for certain emotions (genuine from feigned positive) when given sufficient processing time, however, dynamic cues are informative for recognising emotion blends (e.g., smiling in confusion). This indicates difficulties processing complex emotion responses in ASD.
