the most frequently viewed stimuli receives the greatest activation in the FFA as seen in the greebles study (Gauthier et al., 2000). Development of the FFA and PPA in the brain Some research suggests that the development of the FFA and the PPA is due to the specialization of certain visual tasks and their relation to other visual processing patterns in the brain. In particular, existing research shows that FFA activation falls within the area of the brain that processes the immediate field of vision, whereas PPA activation is located in areas of the brain that handle peripheral vision and vision just out of the direct field of vision (Levy et al., 2001). This suggests that the FFA and PPA may have developed certain specializations due to the common visual tasks within those fields of view. Because faces are commonly processed in the immediate field of vision, the parts of the brain that process the direct field of vision eventually also specialize in more detailed tasks like face recognition. The same concept applies to place: because buildings and locations are often viewed in their entirety either right outside of the field of vision or in an individual's periphery, any building or location visual specialization will be processed within the areas of the brain handling peripheral vision. As such, commonly seen shapes like houses and buildings become specialized in certain regions of the brain, i.e. the PPA.
