This is my first attempt to simulate some aspects of Barsalou's perceptual symbol system theory.
Abstract: We explore the possibility for a situated system to evolve what Barsalou calls a perceptual symbol system (PSS). We describe the peculiarities of perceptual symbols and point out the main capabilities of organized, multimodal frames of perceptual symbols called simulators. We present a case study in which perceptual symbols and simulators are evolved and exploited for categorization, prediction and abstraction.

I am a researcher at the Institute of Cognitive Sciences and Technologies, CNR, in Rome. You can look at my publications, or at my curriculum vitae, or contact me: giovanni.pezzulo(AT)istc.cnr.it I got a degree in Philosophy of Science and a PhD in Cognitive Psychology. My interests are both theoretical and computational, with several topics: anticipation and anticipatory behavior (in the framework of the EU funded project MindRACES); cognitive architectures (trying to bridge sensorimotor interaction with high-level cognitive capabilities such as practical reasoning); goal-oriented behavior; representations (theoretical and computational models); motivations (and their roles in determining behavior); decision making (theoretical and computational models, some experimental work).
