This article describes work carried out to investigate whether a classic reaction-diffusion (RD) system could be used to control a minimally cognitive animat. The RD system chosen was that first described by Gray and Scott, and the minimally cognitive behaviors were those used by Beer et al. involving the fixation and discrimination of diamond and circle(More)
Bumblebees will learn to approach one of a pair of patterns (a 45 degrees grating) and to avoid the other (a 135 degrees grating) to reach a feeder, and to do the opposite to reach their nest (approach a 135 degrees grating and avoid a 45 degrees grating). These two potentially competing visuo-motor associations are insulated from each other because they(More)
BACKGROUND An animal's behavioral strategies are often constrained by its evolutionary history and the resources available to it. Artificial evolution allows one to manipulate such constraints and explore how they influence evolved strategies. Here we compare the navigational strategies of flying insects with those of artificially evolved "animats" endowed(More)
Bees have the flexibility to modulate their response to a visual stimulus according to the context in which the visual stimulus is seen. They readily learn that in one context a yellow target, but not a blue one, should be approached to reach sucrose and that in another context blue, but not yellow, leads to sucrose. Here we contrast the bumblebee's ability(More)
This paper describes work carried out to investigate whether a classic simulated reaction-diffusion (RD) system could be used to control a 'minimally cognitive' animat during the course of a simple memory test. This test required the animat to remember an arbitrary signal and adapt its behaviour as a result. A further requirement was that the effects of the(More)

A list of reviewers will be published in each December issue. This has been done in order to ensure the anonymity of reviewers for each paper. which is a small series of slides, succinctly written by yet another(More)
