Model comparison for OV_reward and OV_goal effects on RT across studies

Model	Study 1					Study 2
	R 2	AIC	dAIC	X2	p	R 2	AIC	dAIC	X2	p
Model 0 (baseline): VD + Cb-w	0.22	4112				0.19	4396
Model 1: baseline + OVreward	0.22	4112	0	2.72	0.099	0.19	4398	2	0.04	0.847
Model 2: baseline + Cb-w: OVreward	0.26	3956	−156	157.68	<0.001	0.25	4197	−202	203.31	<.001
Model 3: baseline + OVgoal	0.26	3957	1	2.59	0.108	0.25	4195	−2	0.06	0.809

For each study, models are compared sequentially, and dAIC is the difference in AIC of each model to the previous model. VD Value Difference, OV overall value, significant effects are highlighted in bold
