Abstract:

Williams Syndrome (WMS) and Autism Spectrum Disorder (ASD) are neuro-developmental disorders associated with distinct social phenotypes. Infant and young children associated with these two disorders provided evidence of developmental delay. This paper attempts on analyzing the extent of convergence and divergence of the behaviours in WMS and the symptoms of ASD. Features of diagnosis and characteristics, as well as developmental achievements in these two disorders will also be addressed further. Moreover, in depth discussion and comparison on a number of aspects including; intellectual ability, visual-spatial skills, language and communication, social interaction and emotion detection, in regards to both disorders will be dealt in detail throughout the rest of this paper.
