 Lloyd’s and Grush’s approaches to studying temporal representation are varied in their emphases. But they are unified in their implicit commitment to localizing cognitive functions and decomposing them into subfunctions using both top-down and bottom-up constraints. (See Bechtel and Richardson 1993 for more details on this general explanatory strategy.) As we mentioned a few paragraphs above, both anticipated in important and interesting ways more recent neuroscientific and philosophical work on predictive coding and the brain. Both developed mechanistic explanations that pay little regard to disciplinary boundaries. One of the principal lessons of Bickle’s and Craver’s work is that neuroscientific practice in general is structured in this fashion. The ontological consequences of adopting this approach continue to be debated.
