p268fig06.15 The largest salient feature signal is chosen to determine the next target position of a saccadic eye movement.  This This target position signal self-inhibits to enable the next most salient position to be foveated.  In this way, multiple feature combinations of the object can be foveated and categorized.  This process clarifies how the eyes can explire even novel objects before moving to other objects.  These eye movements enable invariant categories to be learned.  Each newly chosen target position is, moreover, an "attention pointer" whereby attention shifts to the newly foveated object position.<BR>||  How are saccades within an object determined? Figure-ground outputs control eye movements via V3AA! Support for prediction (Theeuwes, Mathot, and Kingstone 2010), More support: "attention pointers" (Cavanaugh etal 2010), Even more support (Backus etal 2001, Caplovitz and Tse 2006, Galletti and Battaglia 1989, Nakamura and Colby 2000)
