Demographic information and differences between groups.

	ASD group	TD group
Sex (M:F)	12:5 (N = 17)	11:7 (N = 18)
Age, mean years (range)	21.5 ± 3.2	22.7 ± 6.0
LQ, mean (range)	68.9 ± 36.9	82.1 ± 33.3
AQ, mean (range)**	32.6 ± 8.1	20.1 ± 6.2
VIQ, mean (range)	111.8 ± 16.0	115.5 ± 12.1
PIQ, mean (range)	105.4 ± 17.8	112.4 ± 13.5

**p < 0.01. M, male; F, female; ASD, autism spectrum disorder; TD, typically developing; LQ, laterality quotient; AQ, Autism spectrum Quotient; VIQ, verbal intelligence quotient; PIQ, performance intelligence quotient; FIQ, full-scale intelligence quotient. The AQ score was evaluated by the Autism spectrum Quotient (AQ) scale. The LQ score was assessed using the Edinburgh Handedness Inventory (Oldfield, 1971). The intellectual quotients (IQs) were assessed by the Wechsler Adult Intelligence-Third Edition (WAIS-III). Asterisk indicates significant difference between groups found by two-tailed t test.
