Trial sequence for visual search task
A normalization model of visual search predicts single trial human fixations in an object search task.
... Nevertheless, it is clear that the task is not trivial, yet both humans and the model can successfully localize the target within a small (and similar) number of fixations. The overall similarity between ...
