TABLE 1.

Terminology and Formulas Used to Examine Pattern Separation and Pattern Completion

	Response
Item Type	“New”	“Similar”	“Old”
Novel	Correct rejection rate	Similar bias rate	False alarm rate
Lure	Incorrect	Pattern separation rate	Pattern completion rate
Repeated	Miss Rate	Incorrect	Hit rate

All rates express as a percentage.

Bias corrected pattern separation score (BPS) = (pattern separation rate – similar bias rate).

Bias corrected pattern completion score (BPC) = (pattern completion rate – false alarm rate).
