....biology is the origin and home of selectionist theories of evolution. 2. Psychology and cognitive science Already mentioned is that selectionist accounts of cognition arose beginning in the nineteenth century and that detailed computational versions are in play today in biology (e.g. [10, 20]) Indeed, most of the field of cognitive science, and very much of artificial intelligence, can be understood as seeking computational models of cognition. 17 3. Economics (and commerce) The work of Nelson and Winter was discussed at length above [45, 46] It has produced, or is associated ....

....rich intrinsic dynamics, which can be connected to form CTRNNs exhibiting complex dynamical behavior. The CyberLife networks are divided into a number of distinct lobes : There are connections both within and between lobes, in a manner reminiscent of the computational neuroscience work of Edelman [13]; this contrasts with the majority of research in arti#cial neural networks, where no such global structure is imposed. For a recent collection on modular approaches to arti#cial neural networks, see [43] Empirically, the dynamics of the networks in Creatures are stable while avoiding ....

Dynamical and embodied models of cognition [1, 2, 3, 4, 5, 7, 8, 10, 11, 12, 13] are beginning to o er new insights into how the numerous, heterogeneous elements of neural structures may self organize during the development of the organism in order to e ectively form adaptive categories and increasingly sophisticated skills, strategies and goals. The ontogenetic development ....

....If such patterns are to drive our abilities to perform search operations, then we need to understand their nature before we understand how we may exploit them. What, after all, are patterns of visual stimuli One fruitful way to approach this question is to consider the research of Gerald Edelman (1987). For over a decade Edelman has been investigating the construction of automata that not only are capable of general visual perception but also have designs that reflect our knowledge of the neural architectures that support biological perception. Edelman s model takes a two stage approach to the ....

....object shape, and edge relationships of the sort one might encounter in a hand drawn sketch (Furht, Smoliar, and Zhang, 1995) However, while the technology for representing an object s shape is promising, the segmentation technology that identifies an object in the first place is far weaker. As Edelman (1987) has demonstrated, that technology requires building beyond the recognition of features to the more sophisticated identification of actual patterns. Consequently, even the representation of features such as color and texture still cannot be readily associated with objects, but only with either the ....

The algorithm operates in a selectionist manner: grammars that succeed in analyzing input sentences are rewarded, and those that fail are punished. There is neurological evidence (Hebb 1954; Hubel Wiesel 1962; Changeux 1983; Edelman 1987; inter alia) that the development of neural substrate is guided by the exposure to specific stimulus in the environment in a Darwinian selectionist fashion (cf. Lightfoot 1991) 2.3 The asymptotic behavior of the learner For simplicity, assume that there are two grammars (N = 2) the target ....

....desired intelligent behaviour indeed this depends very much on the environmental constraints and the network constraints in the form of the types of functionality available from the modules. The call for a step in the direction of the development of modular systems has frequently been made [Sel59, Min85, MP88b, Ede87, Mel88], but up till now most of the emphasis has been on developing small modular systems specialized as a whole for a particular task domain [Wai89, NKK90, SNA89, Ebe89] rather than systems capable, merely through a higher level alteration in the specification of the architecture or environment ....

Keeping the same architecture, a study of more complex cognitively related tasks, such as pattern association (in ....

....schemes between, for instance, the sensory systems and memory structures to assure the reliable transduction of sensory states into internal representations. The practical problem is that the genome does not have the necessary amount of genes to be able to accomplish this job [Changeux 1985, Edelman 1987]. Of the some 50 000 genes involved in realizing the whole vertebrate phenotype only around 30 000 correspond to the brain. That they are expressed in the brain, however, does not mean that they are all necessary to develop one [Miklos 1993] This is one of the reasons to assume that the brain is ....

If one, in the face of this first problem, would still like to insist on the The mind brain dilemma 139 implied nativism of cognitivism, one must still explain how, during evolution, all this knowledge could have accumulated in our genes (e.g. Piaget in [Piatelli Palmarini 1980] Some might ....

....later. Much in the same way as Darwinian processes are the driving force for the evolution of species, Darwinian like processes are responsible for functional adaptation of the nervous system and the brain to its possessors environment and tasks. Edelman s neuronal group selection theory [ Edelman, 1987 ] shows how different neural functionality is in constant competition during development and adulthood. Very much like a micro ecology, in which often used pathways tend to get the upper hand, while unused pathways disappear. This selectionistic process requires two ingredients: a source of ....

....It is top down because the most general distinctions are created before refinements are made. It is selectionist because distinctions are created and then subjected to selection pressure coming from success in discrimination. In this respect the proposed system is related to Edelman s proposals [1] except that selection comes from discrimination and not classification. It is adaptive because it keeps expanding to cope with the steady stream of new objects entering the environment, and thus not settle into an equilibrium like a Kohonen network for example [2] 2.2 Implementation Results ....

....compact internal representations that are observed in the pseudo recurrent network. This could help shed light on the phenomenon of age related categorical brittleness without requiring, for example, an appeal to mechanisms of neural pruning that have been suggested elsewhere (see, for example, Edelman, 1987). In addition, the more compact representations would tend to exhibit a greater sensitivity to damage, which might help to explain certain memory losses that accompany senescence. 24 Experiment 5 shows that this model, unlike standard backpropagation models, exhibits a plausible list length ....

For instance, adaptive mechanisms have been borrowed and used metaphorically (e.g. epidemiological notions of contagion used to model the spread of innovations, Cavalli Sforza Feldman, 1981) or literally, e.g. the concept of competitive exclusion underlying neural Darwinism, Edelman, 1987) However, fundamental research into the unique character of these non biological adaptive systems should eventually reify or replace these placeholders (e.g. Gatherer, 1998) The prospect of multiple levels of adaptation interacting with one another further complicates the picture. The learning ....

This allows organisms to learn from experience during their lifetimes, i.e. is a type of acquired characteristic with clear survival value. However, until the advent of language and culture, which permit intergenerational ....
