 When evaluating cognitive science support for LOTH, it is crucial to specify what version of LOTH one has in mind. Specifically, establishing that certain mental processes operate over mental representations is not enough to establish RTT. For example, one might accept that mental representations figure in perception and animal navigation but not in high-level human cognition. Gallistel and King (2009) defend COMP+CCTM+FSC through a number of (mainly non-human) empirical case studies, but they do not endorse RTT. They focus on relatively low-level phenomena, such as animal navigation, without discussing human decision-making, deductive inference, problem solving, or other high-level cognitive phenomena.
