Figure 11. Systems combined in the model and the variants.
Variants of the model rely on the same architecture (described in Figure 2) and only differ in the combined systems. Colours are shared for similar systems. (A) The model combines a Model-Based system (MB, in blue) and a Feature-Model-Free (FMF, in red) system. (B) Variant 1 combines a Model-Free system (MF, in green) and a Feature-Model-Free system. (C) Variant 2 combines a Model-Free system and a Bias system (BS, in grey), that relies on values from the Model-Free system. (D) Variant 3 combines a Model-Free system and two Bias systems, that rely on values from the Model-Free system. Variant 4 is not included as it failed to even reproduce the autoshaping behavioural results.
