Perceptual Symbol Systems theory has also been used to account for both prediction and the simulation of novel events. Barsalou (2009) states that when we encounter a familiar situation, sensorimotor based representations of the situation are activated. Given that this form of simulation is essentially indexing a specific pattern of sensorimotor activation, this form of grounded representation may then serve as a rich source for prediction through pattern completion mechanisms. In addition, novel events may be simulated by combinatorially and recursively combining discrete aspects of simulation from known concepts. Barsalou also suggests that such processes underlie the experiences of proprioception and introspection. Specifically, Barsalou (1999) notes that the experience of introspection may be associated in tandem with sensorimotor based representations, and thus allow the representation of complex abstract concepts that were previously thought to be outside the scope of grounded theory. Perceptual symbol systems theory has served as a pioneering model of  grounded processing, and has been especially influential in modelling the embodiment of linguistic symbols within cognition and the broad role of simulation within conceptual representation.
