Idea generation is a fundamental attribute of the human mind, but the cognitive and neural mechanisms underlying this process remain unclear. In this paper, we present a dynamic connectionist model for the generation of ideas within a brainstorming context. The key hypothesis underlying the model is that ideas emerge naturally from itinerant attractor(More)
— Brainstorming is the process of generating ideas in a specific task or problem context. We have previously presented a connectionist framework to study the dynamics of idea generation in individuals. In this paper, we develop this model further, and apply it to studying qualitatively the effects of priming on the process of ideation. Motivated by(More)
— Cognitive control-the ability to produce appropriate behavior in complex situations-is a fundamental aspect of intelligence. It is increasingly evident that this control arises from the interaction of dynamics in several brain regions, and depends significantly on processes of modulation and dynamical biasing. While most research has focused on(More)
— Understanding the neural mechanisms of the idea generation process has implications for research in brain-storming, creativity and innovation. In this paper we present a conceptual neural model for generating ideas. The model extends the associative memory model of Brown et al. (1998) by explicitly representing categories as networks of concepts and ideas(More)
This article develops the cognitive-emotional forager (CEF) model, a novel application of a neural network to dynamical processes in foraging behavior. The CEF is based on a neural network known as the gated dipole, introduced by Grossberg, which is capable of representing short-term affective reactions in a manner similar to Solomon and Corbit's (1974)(More)
The activation-selection model (ASM) of determining the meaning of an ambiguous word is unique in that it is able to account for the long-term effects of meaning selection without an explicit mechanism for suppressing the representation of the nonselected meaning. The model assumes that a meaning is selected when a threshold number of attributes associated(More)
Modelers of cognitive processes have been identified as belonging to one or the other oftwo camps: inhibitophiles or inhibitophobes (see chap. 15, this volume). Therefore, it seems reasonable to make clear our points of view on the issue that underlies this volume, namely, what is the proper role of the construct of inhibition in cognitive theory?

Thought is an essential aspect of mental function, but remains very poorly understood. In this paper, we take the view that thought is a response process – the emergent and dynamic configuration of structured response , i.e., ideas, by composing response elements, i.e., concepts, from a repertoire under the influence of afferent information, internal(More)
