Understanding emotions from standardized facial expressions in autism and normal development.

Castelli (2005) showed photos of happy, sad, angry, scared, surprised, and disgusted faces to two groups of children. One group had autism. The other group was typically developing. The kids named the feeling or picked a matching word. Tasks stayed the same for every child.

Both groups got the six basic emotions right equally often. The autistic children were just as fast and accurate as their peers. The study found no general face-reading deficit for simple, clear expressions.

Fink et al. (2014) ran a similar test and saw the same null result once verbal skill was held constant, giving a direct replication. Song et al. (2018) seems to disagree; they found autistic kids needed stronger intensity to spot anger, fear, and disgust. The clash disappears when you see Yongning used faint, blended faces while Fulvia used full-strength photos. Evers et al. (2015) extended the idea to short video clips and showed a small global lag, not a specific emotion problem, after correcting for response bias.

If you teach social skills, do not assume every autistic learner cannot read a face. Start by checking if they name basic emotions correctly; many can. When errors show up, first rule out language level, then test with subtler or moving faces before writing a deficit goal. Target intensity training or dynamic clips only after clear photos are mastered.
