summaryTheories of human visual selection have typically assumed that attention is limited to one object at a time (e.g., Duncan, 1984, JEP:Gen.). However, what defines an object in such cases is unclear. I will present evidence from experimental studies with normal observers and with neuropsychological patients that the 'objects' selected for action can be determined by the potential for action between stimuli. The representations mediating these effects depend on stimuli being coded within an egocentric reference frame and they are strongly affected by object orientation. ERP experiments indicate an early response to actionrelated properties of objects mediated by parietal and frontal regions. The data indicate a critical role for action in 'driving' human attention.
