The symbolic approach views cognition as computation involving symbolic manipulation. Connectionism, a special case of associationism, models associations using artificial neuron networks. Peter G rdenfors offers his theory of conceptual representations as a bridge between the symbolic and connectionist approaches.Symbolic representation is particularly weak at modeling concept learning, which is paramount for understanding many cognitive phenomena.

His aim is to present a coherent research program that can be used as a basis for more detailed investigations.","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50320941941009,"sku":"CIN0262572192G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50616604950801,"sku":"GOR007526148","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51330629304593,"sku":"CIN0262572192VG","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ NEW \/ INGRAM","offer_id":52137817899281,"sku":"NLS9780262572194","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0262572192.jpg?v=1751227648"},{"product_id":"knowledge-in-flux-book-peter-gardenfors-9781904987895","title":"Knowledge in Flux","description":"This is a new edition of Gardenfors' classic text, presented to the community with a Foreword by David Makinson and an appendix containing a paper Relations between the logic of theory change and nonmonotonic logic by the author and David Makinson. The following describes the first edition: Knowledge in Flux presents a theory of rational changes of belief, focusing on revisions that occur when the agent receives new information that is inconsistent with the present epistemic state. It brings together, systematises and enlarges upon an already influential body of work by the author and his colleagues on the dynamics of theories and epistemic states. The problem of knowledge representation is one of the most important current research problems in philosophy, artificial intelligence, and cognitive science in general. While most of the research has been devoted to analysing the structure of epistemic states, this book is unique in describing the dynamics of knowledge and belief, and in presenting models of knowledge that focus on expansions, revisions, and contractions of epistemic states. Knowledge in Flux is sure to be widely recognised as the most important systematic contribution to these issues yet made. David J. Israel, Senior Computer Scientist, SRI International Peter Gardenfors is a Professor in Cognitive Science at Lund University.","brand":"WoB","offers":[{"title":"US \/ NEW \/ INGRAM","offer_id":51053886734609,"sku":"NIN9781904987895","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":51420976316689,"sku":"GOR014269253","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ NEW \/ INGRAM","offer_id":52140456345873,"sku":"NLS9781904987895","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1904987893.jpg?v=1750931871"},{"product_id":"geometry-of-meaning-book-peter-gardenfors-9780262533751","title":"The Geometry of Meaning","description":"A novel cognitive theory of semantics that proposes that the meanings of words can be described in terms of geometric structures.In The Geometry of Meaning, Peter G rdenfors proposes a theory of semantics that bridges cognitive science and linguistics and shows how theories of cognitive processes, in particular concept formation, can be exploited in a general semantic model. He argues that our minds organize the information involved in communicative acts in a format that can be modeled in geometric or topological terms--in what he terms conceptual spaces, extending the theory he presented in an earlier book by that name.Many semantic theories consider the meanings of words as relatively stable and independent of the communicative context. G rdenfors focuses instead on how various forms of communication establish a system of meanings that becomes shared between interlocutors. He argues that these meetings of mind depend on the underlying geometric structures, and that these structures facilitate language learning. Turning to lexical semantics, G rdenfors argues that a unified theory of word meaning can be developed by using conceptual spaces. He shows that the meaning of different word classes can be given a cognitive grounding, and offers semantic analyses of nouns, adjectives, verbs, and prepositions. He also presents models of how the meanings of words are composed to form new meanings and of the basic semantic role of sentences. Finally, he considers the future implications of his theory for robot semantics and the Semantic Web.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51681701396753,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":51681701691665,"sku":"GOR010916148","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ NEW \/ INGRAM","offer_id":52690893046033,"sku":"NLS9780262533751","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0262533758.jpg?v=1751227605"},{"product_id":"dynamics-of-thought-book-peter-gardenfors-9781402033988","title":"The Dynamics of Thought","description":"Having said this, I still think that there is a common theme to my work over the years: The dynamics of thought.

Since the focus of my research interests has shifted several times during this period, it would be difficult to identify a common theme for all the papers in the volume. Following the Swedish tradition, I therefore present this as a smorgasbord of philosophical and cognitive issues that I have worked on. To create some order, I have organized the sixteen papers into five general sections: (1) Decision theory; (2) belief revision and nonmonotonic logic; (3) induction; (4) semantics and pragmatics; and (5) cognition and evolution. Having said this, I still think that there is a common theme to my work over the years: The dynamics of thought. My academic interests have all the time dealt with aspects of how different kinds of knowledge should be represented, and, in particular, how changes in knowledge will affect thinking. Hence the title of the book.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52662716006673,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ INGRAM","offer_id":52662716760337,"sku":"NLS9789048168545","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9789048168545.jpg?v=1787139828"},{"product_id":"cognition-education-and-communication-technology-book-peter-gardenfors-9780805842807","title":"Cognition, Education, and Communication Technology","description":"This book presents some of the recent theoretical developments in the cognitive and educational sciences and the implications for the use of ICT in the organization of school and university education.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":53637205033233,"sku":"NLS9780805842807","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780805842807.jpg?v=1785766028"},{"product_id":"belief-revision-book-peter-gardenfors-9780521412605","title":"Belief Revision","description":"Belief revision is a topic of much interest in theoretical computer science and logic, and it forms a central problem in research into artificial intelligence. In simple terms: how do you update a database of knowledge in the light of new information? What if the new information is in conflict with something that was previously held to be true? An intelligent system should be able to accommodate all such cases. This book contains a collection of research articles on belief revision that are completely up to date and an introductory chapter that presents a survey of current research in the area and the fundamentals of the theory. Thus this volume will be useful as a textbook on belief revision.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":53737144942865,"sku":"GOR015021692","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780521412605.jpg?v=1786114137"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-peter-gardenfors.oembed","provider":"World of Books ","version":"1.0","type":"link"}
