“…Whereas some studies have reported results consistent with object-based attention selecting a location-independent representation, where attention selects the features of an attended object, such as its shape, color, orientation, and texture, without selecting its spatial location (e.g., Awh, Dhaliwal, Christensen, & Matsukura, 2001;Matsukura & Vecera, 2011;O'Craven et al, 1999;Vecera & Farah, 1994), other studies have found that object-based attention selects from a location-mediated representation, where attention selects the regions of space occupied by the attended object (e.g., Kim & Cave, 1995;Martínez et al, 2007;Martínez et al, 2006;Müller & Kleinschmidt, 2003;Valdes-Sosa et al, 1998;Vecera & Farah, 1994;Weber et al, 1997). As was mentioned earlier, Vecera and Farah (see also Vecera, 1994) referred to these two types of selection as spatially invariant and grouped-array selection, respectively.…”
