Emotion recognition (ER) and understanding deficits are characteristic of autism spectrum disorder (ASD). The Transporters (TT) animated series has shown promising results in teaching children with ASD to recognize emotions, with mixed findings about generalization and maintenance of effects. This study aimed to evaluate the unique role of TT and of parental support in the acquisition, generalization, and maintenance of acquired ER skills in children with ASD. 77 Israeli children with high functioning ASD, aged 4–7 were randomly assigned into four groups according to a 2 × 2 design of the factors Series (TT, control series) and Parental Support (with/without). Thirty typically developing children, matched to the ASD groups on mental age, were tested with no intervention. Participants' ER (on three generalization levels) and emotional vocabulary (EV) were tested pre and post 8 weeks of intervention, and at 3 months' follow‐up. Compared to the control series, watching TT significantly improved children's ER skills at all generalization levels, with good skill maintenance. All groups improved equally on EV. The amount of parental support given, in the groups that had received it, contributed to the generalization and maintenance of ER skills. Autism severity negatively correlated with ER improvement. The current study provides evidence to the unique role of TT in ER skill acquisition, generalization, and maintenance in children with high functioning ASD. In addition, this study provides evidence for a successful cultural adaptation of TT to a non‐English speaking culture.
