Summary of each model and brief description of differences.

Name	Feedback type	Switching type	Description
Model 0 (2FB-SS)	Independent (2FB)	Soft (SS)	Original formulation of COVIS where each system receives independent feedback and either system controls responding on a trial-by-trial basis.
Model 1 (1FB-HS)	Single (1FB)	Hard (HS)	Each system is only updated with a single feedback signal from the responding system; switching from explicit to procedural responding occurs once.
Model 2 (1FB-SS)	Single (1FB)	Soft (SS)	Each system is only updated with a single feedback signal from the responding system; system switching is on a trial-by-trial basis.
