The crux of the debate between ourselves and Bertenthal and Scheutz (2013) (B&S) is whether imitative compatibility effects reflect the operation of specialized imitation-related mechanisms or instead arise from the same associative learning processes thought to underlie spatial compatibility effects. Our conclusions were, and remain, more modest than B&S imply. We do not claim that our model rules out the possibility that spatial and imitative compatibility depend on qualitatively distinct processes, but we believe it supports a “same mechanisms” over a “different mechanisms” view.
