The shapes of contours and textured surfaces are important for visual object recognition (Biederman,
1987; Marr,
1982). Studies attest to the idea that contour shapes and texture shapes are processed by different mechanisms (Grigorescu, Petkov, & Westenberg,
2003,
2004; Petkov & Westenberg,
2003), though whether they are processed in different cortical areas is less clear. It is believed that contour shapes are processed in extrastriate areas such as V4 and infero-temporal cortex (IT) (Brincat & Connor,
2004; Ito, Fujita, Tamura, & Tanaka,
1994; Ito, Tamura, Fujita, & Tanaka,
1995; Pasupathy & Connor,
2002), and although some evidence points to textures being processed in primary visual area V1 (Dumoulin, Dakin, & Hess,
2008), most evidence suggests that a variety of extrastriate areas are involved in processing different aspects of and different types of textures (Baker, Mortin, Prins, Kingdom, & Dumoulin,
2006; Cant & Goodale,
2007; Cant, Large, McCall, & Goodale,
2008; Cavina-Pratesi, Kentridge, Heywood, & Milner,
2010; Kastner, De Weerd, & Ungerleider,
2000).
