How the human brain recognizes and differentiates objects from one another and likewise groups them into categories according to common features/actions has been a topic of neuropsychological and neuroscienti c investigation for several decades. For example, ventral posterior temporal cortices have been found to play a major role not only in object processing in general (see Tanaka, 1997; Ungerleider and Haxby, 1994 for reviews), but also in category-selective processing (Moore and Price, 1999; Peissig and Tarr, 2007; Perani et al., 1995, 1999). One axis along which objects appear to be differentiated is whether their referent is something living or an artifact (i.e., manufactured). This distinction appears to hold true for visually presented stimuli (e.g., Caramazza and Shelton, 1998; Gerlach, 2007; Martin, 2007) as well as their auditory counterparts (Lewis et al., 2005; Murray et al., 2006). In addition to this categorical distinction, there is abundant evidence that the processing of faces
(and places) may recruit highly specialized neural circuitry (e.g., Bentin et al., 2007; Kanwisher and Yovel, 2006). One perspective is that such specialized responsiveness follows from the social importance of faces in human interactions. More recently, investigations have revealed that objects and words can also be differentially processed according to their associated actions by regions of the ventral premotor cortex and posterior parietal areas (see Culham and Valyear, 2006; Johnson-Frey, 2004; Lewis et al., 2005; Pulvermuller, 2005 for reviews).
