Adaptive information processing is crucial for flexible brain function and spatial attention is a quintessential example of this process. It is crucial for recognizing and interacting with behaviorally relevant objects in a cluttered environment. How the deployment of spatial attention aids hierarchical computations of object recognition is unclear. Two key mechanisms have been proposed: First is an improvement in the efficacy of information transfer, supported by an attentional increase in inter-areal correlations along the hierarchy. A second proposal is an improvement in information capacit
