The notion of a universal semantic cognitive map is introduced as a general indexing space for semantics, useful to reduce semantic relations to geometric and topological relations. As a first step in designing the concept, the notion of semantics is operationalized in terms of human subjective experience and is related to the concept of spatial position. Then synonymy and antonymy are introduc...

Externalist theories in natural language semantics have become the orthodoxy since Kripke is widely thought to have refuted descriptive theories involving internal cognitive representation of meaning. This shift may be seen in developments in philosophy of language of the 1970s – the direct reference “revolution against Frege” (Wettstein 2004, 66). Almog (2005, 493) writes of the “uprising agai...

A user experiment on multimodal interaction (speech, hand position and hand shapes) to study two major relationships: between the level of cognitive load experienced by users and the resulting multimodal interaction patterns; and how the semantics of the information being conveyed affected those patterns. We found that as cognitive load increases, users’ multimodal productions tend to become se...

Cognitive architectures are used to abstract and simplify the process of computational cognitive modeling. The popular cognitive architecture ACT-R has a well-defined psychological theory, but lacks a formalization of its computational system. This inhibits computational analysis of cognitive models, e.g. confluence or complexity analysis. In this paper we present a source to source transformat...

We review the various explanations that have been offered to account for subjects’ behaviour in Wason’s famous selection task. We argue that one element that is lacking is a good understanding of subjects’ semantics for the key expressions involved, and an understanding of how this semantics is affected by the demands the task puts upon the subject’s cognitive system. We make novel proposals in...

This paper addresses the two way relation between the ar chitecture for cognitive robots on one hand and a logic of action and change that is adapted to the needs of such robots on the other hand The relation goes both ways the logic is used within the architecture but we also propose that an abstract model of the cognitive robot archi tecture shall be used for de ning the semantics of the logi...

There are two different approaches to meaning formalization: one logical, another cognitive. The logical approach, going back to Frege and developed and explicitly applied to natural language semantics by Montague, is characterized by establishing semantics from primitive semantic structures of sentential type. This approach is most consistently represented by type logical grammars (see collect...
