Experimental paradigm and trial presentation order. A: Schematic of the scanning experimental paradigm and trial presentation order. One feature knowledge type (habitat or diet) was taught about all the animals before the other knowledge type. Two participant groups were taught the knowledge types in different orders. During instruction trials, participants were asked to silently read and remember the animal name, and imagine and think about the animal embodying only the new feature description. During thinking trials, participants were asked to imagine and think about the animal embodying every feature taught about thus far for that animal. The main focus of the data analysis was on activation from the thinking trials, which was hypothesized to constitute the neural representations of the animal concepts. B: Schematic of the full instruction trial and thinking trial presentation order for Cytar, a sample animal (in this example, habitat is learned before diet). Figure S1 contains detailed information for all eight of the animal concept stimuli.
