Proportions of Variance in Recall of Between-List Repetitions in the N-Back Condition Explained by Item Differences and Repetition Detection: Experiments 1 and 2

	Experiment
	1	2
Step 1
Item Differences	.24^*	.13^*
Step 2
Repetition Detection	.14^*	.22^*
Step 3
Interaction	.00	.01

Note: Values displayed above are ΔR² on each step of the model computed at the item level collapsed across participants. Data are from the n-back condition in Experiments 1 and 2. “Item Differences” refers to item differences in single item recall performance, “Repetition Recognition” refers to differences in recognition of between-list repetitions in List 2, and “Interaction” refers to the interaction term for the aforementioned predictors.
