False alarm rate	0	0.05 (0.01)	0.03 (0.01)	0.03 (0.01)	0.47 (0.04)	0.24 (0.03)	0.28 (0.03)

Values are mean (SEM) raw hit rates (ie, proportion of studied items correctly recognized as studied at test) and false alarm rates (ie, proportion of nonstudied items incorrectly recognized as studied at test).
