Subsequent Familiarity and Recollection Performance (d′) for Unexpected and Expected Novel and Familiar Stimuli

	Response	Unexpected	Expected
Novel stimuli	Recollection	0.53 (0.08)***	0.11 (0.10)
	Familiarity	1.17 (0.08)	1.30 (0.08)**
Familiar stimuli	Recollection	0.72 (0.11)***	0.29 (0.16)
	Familiarity	1.14 (0.12)	1.11 (0.13)

Note: The categorization of stimuli as novel and familiar refers to their status in the main recognition task. Familiarity and recollection responses are obtained from the surprise subsequent memory test. Numbers in the parentheses are standard errors of the mean.
