The impact of facial emotion recognition (FER) deficits on facial emotion expression (FEE) during interaction with a novel computerized system was investigated in children with ASD (n = 20), in comparison to typically developing (TD) peers (n = 20). Although there was not clear evidence of impaired FEE, children with ASD showed more atypical FEE. In children with ASD, better FER predicted better FEE when the participants were asked to express a labeled emotion (t(18) = − 2.75, p = .01, d = 1.24). The stronger relationship between FER and FEE in children with ASD, relative to controls, suggests that intervention targeting social communication deficits might have maximal effect when both processes are considered.
