1Fisher’s exact test was used to assess independence of the variables.
2Mean absolute motion and mean relative motion are values that refer to average head motion relative to the reference volume and previous volume, respectively. Both values were estimated using FSL’s MCFLIRT tool.
3Single-subject components that were identified by ICA-AROMA as motion or noise were regressed out (i.e., Components removed). The number of remaining components were reported as ‘Components kept.’
ASD, Autism spectrum disorder; TD, Typically developing; WASI, Wechsler Abbreviated Scale Intelligence; SOR, sensory over-responsivity; SCARED, Screen for Child Anxiety Related Disorders. Higher scores of SOR and SCARED indicate more severe SOR and anxiety, respectively.
