Generalized linear mixed-effects model for Correct Rejections (unseen objects) as predicted by Cumulative Interference (continuous, from to 0 to 1) and Visual Similarity (continuous, from 0 to 1 and introduced in the model only for unseen objects). The random variables introduced as intercept and slopes were Participant (71), Semantic Category (27) and Recognition Order (1, 2)

Dependent variable	Predictor	β	Std. β	CI (2.5%; 97.5%)	SE	z-value
Correct rejections	Intercept	2.18	0	1.71; 2.64	0.23	9.2***
	Cumulative Interference	-1.39	-0.88	-2.02; -0.77	0.31	-4.4***
	Visual Similarity	-2.1	-0.79	-2.74; -1.39	0.34	-6***
	Cumulative Interference x Visual Similarity	2.71	1.03	1.74; 3.67	0.49	5.5***

The final model formula in Wilkson notation, resulting from stepwise backward selection is:

‘Correct rejections ~ Cumulative Interference + Visual Similarity + Cumulative Interference x Visual Similarity + (0 + Cumulative Interference | Semantic Category) + (0 + Visual Similarity | Semantic Category) + (1 | Semantic Category) + (1 | Recognition Order) + (1 | Participant) ’
