How does our brain recruit attentional resources? A Review article.


Human information processing is limited by attentional resources. In this review article on multisensory research, we compare studies related to information processing when humans perform object-based and spatial attention tasks. Findings suggest that the attentional system flexibly allocates distinct or shared attentional resources across sensory modalities depending on task
demands. We propose that such flexibility reflects a large-scale optimization strategy that minimizes the brain's costly resource expenditures and simultaneously maximizes capability to process currently relevant information. [link]
