An important goal of semantics is to explain how words refer to objects through context. Connectionist theories are immensely popular in neuroscience at the moment: most cognitive neuroscientists believe that cognition can be explained by the spread of activation over hierarchical, semantic networks. While connectionism can partially explain how the brain understands word reference, I will argue that it cannot explain all phenomena related to reference. Instead, we propose to complement connectionist networks with a separate bundle memory module that allows us to explain a greater range of referential phenomena. Finally, we will make the case that the hippocampus implements this bundle memory module.
