    "subtitle": null,
    "abstract": "Attention plays a fundamental role in higher-level cognition.\nIn this paper we develop a computational model for how\nauditory spatial attention is distributed in space. Our model\nbuilds on the assumption that attentional bias has bottom-up\nand top-down components. We represent each component\nand their synthesis as a map, associating a level of attentional\nbias to locations in space. The maps and their interaction are\nmodeled using an artificial intelligence approach based on\nconstraints. We describe the behavioral task we have\ndesigned to measure the attentional bias and discuss the\nresults. We then test different hypotheses on the shape and\ninteraction modalities of the maps in terms of how well they\nfit our behavioral data. The findings showed that combining\ntop-down and bottom-up spatial attention gradients that differ\nin their spatial properties produced the best fit to behavioral\ndata, and suggested several novel mechanisms for future\ntesting.",
