 Like the precision-optimization theories that have been advocated by Hohwy and Clark, from within the framework of the prediction-error coding theory, the Coherence theories advocated by Neisser, Neumann, Allport, and Wu have also suggested functions for attention other than the management of limitations in processing capacity. Despite the availability of these non-Broadbentian conceptions of attention’s function, the Broadbentian idea that attention’s selectivity serves to manage limitations in processing capacity continues to be regarded by many psychologists as incontrovertible. The claim that “Because the visual system does not have the capacity to process all inputs simultaneously, there must exist attentional processes that help the visual system select some inputs” continues to be treated as a platitude of the sort that can be used as an uncontroversial opening sentence when introducing one’s research. (The example just given comes from the beginning of Vecera (2000), but many more examples of the same claim can easily be found.)
