Statistical analysis for changes in pupil metrics to a 1 and 5 s short wavelength stimulus before and after the experimental period.

Stimulus	PIPR metric	Effect size r	df	t stat	P
1 s	6 s PIPR	0.22	19	1.68	0.06
	30 s PIPR	0.31	19	3.17	^*0.005
	AUC	0.34	19	3.68	^*0.002
5 s	6 s PIPR	0.09	20	−0.08	0.53
	30 s PIPR	−0.04	20	−0.94	0.82
	AUC	0.23	20	2.51	^*0.02

indicates P < 0.05. Key: PIPR: post illumination pupil response; AUC: area under the curve.
