....neural nets and simple reasoning over propositions. In this type of macro agent architecture, there exist many competing and co operating a life communities, at different levels of abstraction. Again as in some of our other work, this builds upon the dynamic systems approach to cognition [12]. From this perspective, cognition is viewed as the changing focus of a number of interacting (sometimes extant, sometimes dormant) processes. Any particular reasoning or problem solving capability can be tuned to a number of related, but different tasks, and that the achievement of complex tasks ....

In other references from the area of cognitive science and philosophy of mind, this omission has been criticised, and instead a different perspective is proposed, where dynamics of mental states and their interaction with the environment are central; e.g. Bickhard, 1993, Port and van Gelder, 1995; Clark, 1997; Christensen and Hooker, 2001; Jonker and Treur, 2002] For example, Bickhard, 1993] emphasizes the relation between the (mental) state of a system (or agent) and its past and future in the interaction with its environment: When interaction is completed, the system will end in ....

Specifications in this specific format have the advantage that they can be used to perform simulation, based on the paradigm of executable temporal logic [Barringer et al. 1996] The approach subsumes discrete simulation, for example as performed in Dynamical Systems Theory [Port van Gelder, 1995] as a special case. A software environment has been implemented including three programs. The first simulates the consequences of a set of temporal relationships of intentional states over time. The second program interprets a given trace of intentional states over time (in terms of beliefs, ....

....This suggests that mental states are grounded in interaction histories on the one hand, and related to future interactions on the other hand. In the recent literature on the interactivist perspective on cognition such as [1] 2] 4] no formalisation is proposed. In literature such as [18] on the dynamical systems approach, modelling techniques based on algebraic and difference or differential equations between continuous numerical variables are commonly used. Some of the questions addressed in this paper are the following. What exactly is an interaction history . How does ....

....coexisting non trivial attractors, like periodic 3 attractors existing together with quasiperiodic or chaotic ones, and in 3neuron networks also co existing chaotic attractors can be observed. Finally, we want to point out, that with respect to the neurodynamics approach to cognitive systems [27], we understand attractors only as classifying instruments. For neural networks serving as embodied cognitive systems, for example as neuro controllers acting in a sensori motor loop, the dynamics always will be that of a driven system. Of relevance for the behavior of such biological or arti cial ....

.... found to relate them to the (physical) world state, and hence symbolic or logical means are of no use to describe cognitive phenomena (the symbol grounding problem) Alternatives put forward (cf. Clapin et al. 2000) include the dynamical systems approach, and the interactionist perspective; cf. (Port and van Gelder, 1995; Bickhard, 1993; Christensen and Hooker, 2000) In line with these, in this paper the dynamic and interactionist perspective is adopted. It is shown how, if an interactionist perspective is taken, logical means in the form of temporal languages and semantics can successfully be used to describe ....

....expressivity, whereas most standard temporal logics are propositional. Secondly, the explicit reference to time points and time durations offers the possibility of modelling the dynamics of real time phenomena, such as sensory and neural activity patterns in relation to mental properties (cf. [Port and van Gelder, 1995]) Third, in our approach states are three valued; the standard temporal logics are based on two valued states, which implies that for a given trace a form of closed world assumption is imposed. This means that, for example, in Concurrent MetateM (cf. Fisher, 1994] if the executable temporal ....

INTRODUCTION Dynamics has become an important focus within Cognitive Science in recent years; e.g. (Port van Gelder, 1995). As one of the aspects, the dynamics of the interaction with the external world, and its implications for the representational content and dynamics of mental states have received attention; e.g. Bickhard, 1993; Christensen Hooker, 2000) Another important aspect is the internal dynamics of ....

....and remembering in the analogic language of dynamics. This situates cognition within the same continuous, time based, and nonlinear processes as those involved in bodily movement, and in the large scale processes in the nervous system (Freeman Skarda 1985; Kelso 1995; Koch Davis 1994; Port van Gelder 1995; Singer 1990; Turvey 1990; van Gelder, 1998) Finding a common language for behavior, body, and brain is a first step for banishing the specter of dualism once and for all. 2.

Several researchers in this new paradigm have claimed that behaviour controlled by hierarchy is necessarily rigid, brittle, and ....

....as a hypothesis of intelligence is that the separation of representation from cognitive process is not necessarily coherent. Many neural theories postulate that an assembly of neurons processes information from perception, from themselves and from each other (e.g. McClelland and Rumelhart, 1988; Port and van Gelder, 1995). This processing continues until a recognized configuration is settled. If that configuration involves reaching the critical activation to fire motor neurons, then there might be only one process running between the perception and the activity. If the levels of activation of the various neurons ....
