Hit Rate, HRb	0.81 ± 0.14h	0.65 ± 0.19h

HC, healthy control; RT, Reaction Time; SZ, schizophrenia.

^aMean ± SD unless indicated otherwise.

^bRetrieve hit rate, HR = [number of correctly identified old words(Hits)]/30.

^cRetrieve percentage correct = (hits + correct rejections)/60.

^dFalse alarm rate, FAR = number false alarms/30.

^eIndex of discriminability, Pr = (HR–FAR).

^fResponse bias, Br = [FAR/(1–Pr)].

^g P < 0.05 corrected significant difference between HC and baseline SZ in independent samples t‐test.

^h P < 0.005 significant difference between HC and baseline SZ in independent samples t‐test.
