Abstract

In contrast to Pylyshyn's view, there is no such thing as “reasoning in general.” Different types of reasoning tasks are solved with different reasoning strategies. A more specific null hypothesis is that spatial inference with mental images involves the same representational formalism as that of spatial inference with mental models. There is no evidence that this hypothesis must be rejected.
