2-Way Interactions¹
Age × C1	.02 (.003)^***	−.01 (.003)^**	.04 (.003)^***
WM × Age	-	.05 (.01) ^***	-
WM × C1	-	.66 (.14)^***	-

Note. WM = Working Memory, C1 = Contrast 1 (NP1 vs. NP2). PE = Print Exposure. ^TThese parameters should not be interpreted as unconditional marginal effects (see Footnote 7).
