Sensory processing problems and impaired social skills are often seen in children with Autism Spectrum Disorder (ASD). Moreover, understanding the gender gap in ASD prevalence and symptomatology is still not achieved. Studies are inconsistent in findings regarding gender specific ASD symptomatology and possible underlying mechanisms of gender differences. This study investigated the relationship between sensory processing and impaired social skills, and whether a mean difference exists in sensory processing symptoms between ASD boys and girls with similar social skills. Method. In this cross-sectional study 169 children (aged 7-12) participated, of which 96 typically developing (TD) and 58 ASD children. All were tested on social skills, measured through the Social Responsiveness Scale and on sensory processing problems, which was mapped out by measures of tapping accuracy, using the DrumPad 2.0 as a rhythmic measurement device. The relationship between sensory processing and social skills was investigated with the use of a Spearman’s Rho test. Mean differences in sensory processing between ASD boys and girls with similar social skills were investigated with the use of a 2x2 ANCOVA. Results. After performing Spearman's Rho test, a significant positive relationship was found in the overall sample between social skills and tapping accuracy. The 2x2 ANCOVA did not prove a significant effect of gender on mean tapping accuracy, but a significant main effect of social skills on the mean tapping accuracy was found. No significant interaction effect of gender and social skills was found. Discussion. Results indicated that social skills and tapping accuracy are associated, and that – after correction for age – social skills have an effect on tapping accuracy, irrespective of gender. To our knowledge, this is the first time that sensory processing was measured through a rhythmic device. This study contributes to the existing literature regarding gender-specific symptomology in ASD.Show less
