Shifting attention in space is a fundamental biological function. Without attention, it would be impossible to scan the environment and to detect prey, predators, or conspecifics. However, attention does not only allow detecting a stimulus of interest. It can be deployed across regions of space that are devoid of any stimulus, or within boundaries defined by an object. While experiments with human participants suggest that different mechanisms may underlie space-based and object-centered attention it has been impossible so far to...
