He has wide-ranging research interests in the philosophy of mind and cognitive science, particularly the extended mind thesis and various forms of socially distributed cognition (for further information, see GeorgTheiner). He regularly referees papers for Philosophical Psychology, Phenomenology and Cognitive Science, The Review of Philosophy and Psychology, Cognitive Science, Topics in Cognitive Science, and Cognitive Systems Research. Georg Theiner joined the Department of Philosophy at Villanova University as Assistant Professor in the fall of Dr. Theiner has also joined the Cognitive Science program as a faculty committee member.

2 Faculty News: Dr. Georg Theiner s Latest Book Res cogitans extensa: A Philosophical Defense of the Extended Mind Thesis by Georg Theiner, Ph.D. What follows is a synopsis of the book written by the author. For René Descartes ( ), considered by many the father of modern philosophy, minds and bodies are fundamentally different kinds of entities. For Descartes, the essence of the mind is to be a thinking yet nonextended thing (res cogitans), whereas the essence of the body is to be an extended yet nonthinking thing (res extensa). In stark contrast to Descartes mind-body dualism, contemporary cognitive science prides itself on having exorcised the Cartesian ghost from the biological machine. However, it seemingly remains committed to the Cartesian vision of the mental as something purely inner. Against the idea that the mind resides solely in the brain, advocates of the situated and embodied nature of cognition have long stressed the importance of dynamic brainbody-environment couplings, the opportunistic exploitation of bodily morphology, the strategic performance of epistemically potent actions, the generation and use of external representations, and the cognitive scaffolding provided by artifacts and social-cultural practices. According to the extended mind thesis (Clark & Chalmers, 1998; Clark, 2008), a significant portion of human cognition literally extends beyond the brain into the body and its environment. My book aims to clarify the nature and the scope of this thesis, and to defend its central insight that cognition is not confined to the boundaries of the biological individual. While our modern-day Cartesian materialists readily acknowledge the empirical insights which have been gained from situated and embodied approaches to cognition, they are typically reluctant to embrace the more radical-sounding implication that bodily and worldly resources may be literally constitutive vehicles of extended cognition, and continue to treat them merely as sources of input for cognition-inthe-head. Such reluctance may well be the symptom of a tacit Cartesian assumption that there must be an indelible mark of the mental an essential feature of mental states that is only found in the brain. As a way of eroding this persisting dogma of cognitive science, consider Gregory Bateson s famous parable: Suppose I am a blind man, and I use a stick. I go tap, tap, tap. Where do I start? Is my mental system bounded at the handle of the stick? Is it bounded by my skin? Does it start halfway up the stick? Does it start at the tip of the stick? But these are nonsense questions. The stick is a pathway along which transforms of difference are being transmitted. The way to delineate the system is to draw the limiting line in such a way that you do not cut any of these pathways in ways which leave things inexplicable (Bateson, 1972). Embracing Bateson s healthy dose of pragmatism, my defense of the extended mind thesis is predicated on showing two things: first, that psychologists and cognitive scientists sometimes profitably treat neural, bodily, and bio-external resources as parts of a single, hybrid system (or process); second, that we have good reasons to consider such systems (or processes) as cognitive. In the course of my book, I present several arguments for extended cognition that are firmly rooted in two successful explanatory frameworks of cognitive science: computationalist functionalism and dynamicism. Those two frameworks are sometimes seen as mutually incompatible approaches to the study of mind and cognition. From our own ecumenical vantage point, however, I offer a reconstruction of both approaches that provides two converging lines of evidence against the persisting dogma of Cartesian materialism, and in favor of our hybrid vision of the extended mind thesis.

3 Alumni News: Shannon Topper While at Villanova, I obtained a Psychology major and Cognitive Science and Theology minors. Since graduating from Villanova in May 2010, I moved to New York City and have been completing a Master s program in Developmental Psychology at Teachers College, Columbia University. Thus far, I have had the opportunity to partake in a number of research endeavors, including independent research on autism and theory of mind as well as lab research on risk and resilience mechanisms among affluent families. In exploring theory of mind among children with autism, I am interested in the specific deficit in mentalizing that may account for difficulties in social interaction. In attempting to more fully understand the underlying mechanisms, I have also focused on the central coherence and executive dysfunction theories of autism. I was also involved in a research practicum exploring maternal adjustment outcomes and variables affecting the maternal need for mothering. Currently, I am working as a research assistant on a project evaluating an early intervention program for very at-risk mothers and babies. I will receive my degree in May, after which time, I will begin a clinical internship in Child Life at the Children s Hospital at Montefiore. In my coursework so far, I have benefitted a great deal from my Cognitive Science minor, as it has instilled in me the necessity of taking an interdisciplinary perspective when exploring different areas of development. My base of knowledge in physiological psychology, cognitive psychology, computer Continued on page 4 Recent Events The Spring edition of the Villanova Cognitive Science Colloquium series was held on March rd, with a stimulating visit by Dr. Larry Barsalou from Emory University. Dr. Barsalou, a world-renown Cognitive Scientist, presented a talk entitled Grounding Knowledge in the Brain s Modal Systems. Contrary to the classic notion that conceptual knowledge is represented in a semantic memory system that is abstract, symbolic, and distinct from perceptual and motor systems, Dr. Barsalou presented a variety of behavioral and neurophysiological evidence to support his Dr. Larry Barsalou thesis that conceptual knowledge is represented and activated by the same brain mechanisms responsible for perception and motor action. The Cognitive Science program recently cosponsored a talk Dr. Mark Greenberg as part the Education and Counseling Week program in the Department of Education and Counseling. Dr. Greenberg, who is the Director of the Prevention Research Center and Professor of Human Development and Psychology at the University of Pennsylvania, presented a talk entitled Nurturing Mindfulness in Families, Schools and Youth: Advancing the Science and Practice of Awareness and Caring. In a very interesting and informative talk, Dr. Greenberg reviewed the mounting scientific evidence (much of it from his own lab) for the effectiveness of mindfulness meditation in treatment settings and in prevention or health promotion contexts.

4 Faculty News (Continued) The dynamicist route refers to the organization of cognitive and sensorimotor processes which arise from the densely coupled interactions between brain, body, and environment. Because of the complex, nested, and highly non-linear nature of these interactions, it is often impossible to understand the dynamics of these hybrid systems by means of traditional decomposition and localization strategies (Bechtel & Richardson, 199). I argue that the dynamicist stance in cognitive science supports a distinctive top-down explanatory style that reveals how cognitively relevant properties of component parts are determined by their participation in the system as a whole. What makes such a dynamical system cognitive is the capacity of integrated brainbody-environment systems to generate particular types of intelligent behavior. The computationalist route is based on a detailed case study of syllogistic reasoning processes that involve the manipulation of external representational systems (e.g., Euler Circles). When mental representations are posited as theoretical entities in computationalist cognitive science, they are expected to do double-duty: first, they ought to have the right kind of semantic content; second, they ought to play a causal role in the production of intelligent behavior. I argue that in the context that I describe, neither internal nor external resources by themselves have the right functional profile to satisfy both the semantic and the causal requirements at once. To guide our behavior, external symbolic representations are dependent on neural mechanisms that operate on perceptually grounded internal representations of those external symbols; however, those inner mechanisms are dependent on external representations to have their syllogistic content fixed. Only their functional integration qualifies the extended computational process as an episode of properly speaking syllogistic reasoning. Our collective fascination with liminal beings creatures such as centaurs, ghosts, or cyborgs that are seemingly caught between two natures and thus elude conventional systems of classification is well-documented in a large body of cultural folklore and literary fiction (Turner, 1969). If the main line of reasoning in Res cogitans extensa is sound, we can add yet another, non-fictional entity to this list: the embodied, embedded, and enculturated human mind. Alumni News (Continued) programming, and philosophy of mind have proven critical as I have explored children s cognitive development, cognition and learning, and atypical development in my current coursework. Specifically, in focusing on the developing mind of the child, I have relied heavily upon my understanding of neurobiology, the interplay between the brain and the mind, and the characteristics of intelligent behavior. Beyond even the immediate influence of my background in cognitive science, I have benefitted from the emphasis placed on interdisciplinary conversation. An understanding of human development requires an integration of many fields, and an openness to a holistic approach is critical in tackling research questions of development. This interdisciplinary perspective that I have gained through the cognitive science program will be of great import in my future academic and professional endeavors. 4
