Means and standard error of physiological features recorded in Experiment 2 from children with ASD (n = 5) and typically developing children (n = 5) during the relaxed state condition and the anxiety-provoking condition.

ASD
Signal feature	Relaxed mean	Anxious mean
EDA (μS) *	4.822, SE = 1.627	7.028, SE = 1.577
Skin temperature (°C)	28.424, SE = 1.512	29.251, SE = 1.918
Blood volume inter-pulse interval (s) *	0.744, SE = 0.024	0.686, SE = 0.022
Respiration inter-breath interval (s)	2.211, SE = 0.337	1.616, SE = 0.174
Typically-developing (Stroop)
Signal feature	Relaxed mean	Anxious mean
EDA (μS) *	4.545, SE = 0.924	8.976, SE = 1.902
Skin temperature (°C)	30.208, SE = 2.218	29.467, SE = 1.875
Blood volume pulse inter-pulse interval (s)	0.757, SE = 0.044	0.706, SE = 0.036
Respiration inter-breath interval (s)	2.987, SE = 0.733	1.546, SE = 0.093

^*Indicates features that were significantly different (p < 0.05) between relaxed and anxious state conditions.
