SRS-2T-score 45.1 ± 5.8 79.3 ± 12.5 t(34.9) = − 13.60, p < 0.001
Non-verbal IQ 106.4 ± 14.8 95.8 ± 21.9 t(33.0) = 2.92, p = 0.006
Overall tactile reactivity 13.6 ± 3.9 25.4 ± 9.1 F(1,65) = 51.43, p < 0.001
Tactile hyper-reactivity 5.7 ± 2.2 10.6 ± 4.6 F(1,65) = 39.3, p < 0.001

  1. All participants had normal or corrected-to-normal vision. Group differences in sex and handedness between children on the autism spectrum (AS) and a neurotypical (NT) comparison group were assessed using chi-square test. Significant effects are indicated in bold
