  1. What Are Natural Concepts? A Design Perspective.Igor Douven & Peter Gärdenfors - 2019 - Mind and Language (3):313-334.
    Conceptual spaces have become an increasingly popular modeling tool in cognitive psychology. The core idea of the conceptual spaces approach is that concepts can be represented as regions in similarity spaces. While it is generally acknowledged that not every region in such a space represents a natural concept, it is still an open question what distinguishes those regions that represent natural concepts from those that do not. The central claim of this paper is that natural concepts are represented by the (...)

  2. Co–Operation and Communication in Apes and Humans.Ingar Brinck & Peter Gärdenfors - 2003 - Mind and Language 18 (5):484–501.
    We trace the difference between the ways in which apes and humans co–operate to differences in communicative abilities, claiming that the pressure for future–directed co–operation was a major force behind the evolution of language. Competitive co–operation concerns goals that are present in the environment and have stable values. It relies on either signalling or joint attention. Future–directed co–operation concerns new goals that lack fixed values. It requires symbolic communication and context–independent representations of means and goals. We analyse these ways of (...)

  3. Representation and Self-Awareness in Intentional Agents.Ingar Brinck & Peter Gärdenfors - 1999 - Synthese 118 (1):89 - 104.
    Several conditions for being an intrinsically intentional agent are put forward. On a first level of intentionality the agent has representations. Two kinds are described: cued and detached. An agent with both kinds is able to represent both what is prompted by the context and what is absent from it. An intermediate level of intentionality is achieved by having an inner world, that is, a coherent system of detached representations that model the world. The inner world is used, e.g., for (...)

    Category-Based Induction in Conceptual Spaces.Matías Osta-Vélez & Peter Gärdenfors - 2020 - Journal of Mathematical Psychology 96.
    Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...)
