Pearson R correlations between PPI and Positive and Negative Syndrome Scale (PANSS) scores for SCZ patients (n=23)

	Overall PPI Session 1	30 ms PPI Session 1	60 ms PPI Session 1	120 ms PPI Session 1
Positive scale Session 1	R=−.12	R=−.09	R=−.20	R=.00
Negative scale Session 1	R=−.20	R=−.41	R=−.06	R=.00
General Scale Session 1	R=−.07	R=−.14	R=−.16	R=.14
Total PANSS score Session 1	R=−.18	R=−.33	R=−.17	R=.08
	Overall PPI change	30 ms PPI change	60 ms PPI change	120 ms PPI change
Positive scale change	R=−.30	R=−.02	R=−.52^**	R=−.11
Negative scale change	R=−.55^**	R=−.54^**	R=−.47^*	R=−.27
General scale change	R=−.29	R=−.18	R=−.41	R=−.03
Total PANSS score change	R=−.48^*	R=−.35	R=−.57^**	R=−.17

“Change” for both PPI and PANSS scores refers to Session 2 value minus Session 1 value.
