“…Although children with WBS appear to be hypersociable when compared to ASD children, both populations share deficits in some socio‐communicative skills, such as, in preschool age, difficulty in shared attention, showing or giving objects and, in school age, difficulty in social relationships comprehension, pragmatic use of language, and emotion's recognition [Vivanti et al, 2018]. Reconsidering phenotypes similarities between WBS and ASD has presumably resulted in a renewed interest in cross‐syndrome studies on phenotypical, behavioral, biological and clinical comparison [Glod, Riby, & Rodgers, 2019; Ashworth, Palikara, & Van Herwegen, 2019; Hamner et al, 2019; Baptista et al, 2019; Lew et al, 2020; Ridley, Riby, & Leekam, 2020].…”
