The article by Arthur B. Markman and Eric Dietrich discusses the perceptual symbol system (PSS) framework, which posits that perceptual representations have a role-argument structure, often in the form of frames. This structure is crucial for supporting conceptual functions such as abstraction and rule-use. The authors highlight the significance of Barsalou's PSS project, which advocates for a more embodied approach to cognition and challenges traditional distinctions between perceptual and conceptual representations. They argue that the capacity to form structured representations, particularly frames, must be innate, as attempts to develop such structures from unstructured representations have been unsuccessful. The PSS approach differs from previous models by tying representational frames closely to perception, which is seen as a bold but promising step. However, the authors emphasize the need to demonstrate how a true perceptual system can generate these structured representations.The article by Arthur B.
