“…This observation is particularly interesting when considering the view of TS having overlapping symptomatology with autism spectrum disorders (ASD) (Mazzola et al, 2006; Skuse, 2005). Indeed, while it is true some characteristic of social behavior seen here correspond to what is observed in ASD, namely autistic mannerisms as measured by the SRS, TS children differ on at least one important point from individuals with ASD in the sense that they are motivated to engage in social interactions, where as children diagnosed with ASD are not (Hong et al 2011). Plausibly, this drive to engage in social relations, coupled with their decreased ability to perceive, analyze, and communicate social information, contribute negatively to self-esteem of girls with TS (McCauley, Ross, Kushner, & Cutler, 1995), and to their perception of isolation (Amundson, Boman, Barrenäs, Bryman, & Landin-Wilhelmsen, 2010) and diminished social competency (McCauley et al, 2001) in adolescence and adulthood.…”
