    "abstract": "We present a computational model of multiple object tracking\nthat makes trial-level predictions about the allocation of\nvisual attention and the resulting performance. This model\nfollows the intuition of allocated resources modulating spatial\nresolution, but it implements it in a specific way that leads to\naccurate predictions in multiple task manipulations. Experiments\non human subjects, guided by the model’s predictions,\ndemonstrate that observers tracking multiple objects use lowlevel\ncomputations of target confusability to adjust the spatial\nresolution at which the target needs to be tracked, and that the\nresulting allocation closely approximates the rational solution.\nWhereas earlier models of multiple object tracking have predicted\nthe big picture relationship between stimulus complexity\nand response accuracy, our approach makes accurate predictions\nof both the aggregate effect of target number and velocity\nand of the variations in difficulty across individual trials\nand targets arising from the idiosyncratic within-trial interactions\nof targets and distractors.",
