Contingency tables for the Independent and Dependent models, giving the frequency (over events) of the four combinations of correct or incorrect retrieval of elements B and C when cued by element A. The Dependent model replaces the probability of correctly recalling B when cued by A (across all events; PAB) with ṔiAB= EiAB(PAB − PG/c) + PG/c, where the episodic factor EiAB reflects performance on event i relative to other events (based on retrievals other than B and C cued by A), PG is the probability of guessing, and c = 6 is the number of choices in a test trial. PAC is replaced similarly (see Supplemental Information for details). The Dependent model equates to the Independent model if the episodic factors are set to 1.
