ASD, Autism Spectrum Disorder; TS, Tourette Syndrome; TD, typically developing; USP-SPS, University of Sao Paulo’s Sensory Phenomena Scale; SP, sensory phenomena; p-values refer to Pearson’s chi-square tests to compare categorical variables between ASD, TS and TD groups (summarized by absolute and percent frequencies).
