fMRI scans done by Kanwisher et al. (1997) showed that the fusiform gyrus in the brain was more active in face recognition than object recognition, this suggests and supports the idea that face recognition involves a separate processing mechanism. This model suggests that we process familiar and unfamiliar faces differently. That we process familiar faces using; structural encoding, FRUs, PINs and Name Generation. However, we use structural encoding, expression analysis, facial speech analysis and direct visual processing to process unfamiliar faces.
However, there is evidence by Young et al. suggesting that the idea of double association is poor. He studied 34 brain damaged men, finding there was only weak evidence for any difference between recognising familiar and unfamiliar faces. An issue with this
