Correlations Between d’ from the DPX and Percent Change Scores from the Emotional Context Processing Task.

Percent Change Scores (from FO condition)	Control (n = 30)	Schizophrenia (n = 30)	Correlation Comparison Across Groups
Negative FC	.15	−.16	Z = 1.15
Positive FC	−.29	−.02	Z =−1.01
Negative FCQ	.09	−.36*	Z = 1.74
Positive FCQ	−.05	−.27	Z = 0.84

Note. We excluded outlier data or cases showing extremely poor performance level (see Supplemental Materials). As such, the total number of participants included in the analysis of DPX was 31 out of 35 in SCZ group and 30 out of 32 in CON group. For the ECPT, the total number of participants was 33 out of 35 for SCZ and 32 for CON. Persons who completed both DPX and ECPT were 30 for each group; To calculate change scores, valence scores in the FO condition were subtracted from valence scores in the positive or negative context or context + question condition, which were divided by valence scores in the no context condition. For example, for the negative context only condition, the change score was ((FC Negative Valence – FO Valence)/FO Valence)*100); FO, Faces Only condition; FC, Faces-Context condition; FCQ, Faces-Context-Question condition; SCZ, individuals with schizophrenia; CON, healthy controls.
