Feature-based visual search and attention. A virtual eye makes a series of saccades to different colour cues and an internal representation of the colour cues is developed on a self-organising map. personalpages.manchester.ac.uk A reward is available for making a saccade to a particular colour and reward expectation is represented in a working memory with the same topology as the self-organising map. As the system learns the rewarding colour, an increasing fraction of the self-organising map represents features in this region, allowing fine distinctions to be made between rewarding and unrewarding shades of the target colour. If the target colour changes then the plasticity of the map increases, allowing focus of representation to shift to another (the newly rewarding) region of the input space. Top left: the entire visual world. The grey area is the region which is currently visible. Bottom left: the working memory representation of rewarding features. This has the same topology as the self-organising map. Bottom centre: the self-organising representation of the different colour cues. Top right: the cumulative number of foveations to each colour. Bottom right: the cumulative number of rewards received. Relevant publication: Brohan, Gurney & Dudek, 2010
