Since into the exclusivity of the FFA and

Since Kanwisher et al’s (1997) original research exploring
the FFA, there has remained much research into the exclusivity of the FFA and
facial perceptions. Kanwisher, Tong and Nakayama, (1998) determined that with
the usage of a fMRI that the FFA reacts to faces. Additional research by
Kanwisher et al (1999) verified whether the human FFA reacts not only to faces
but to anything else, using fMRI the strongest responses were to stimuli
containing faces, results demonstrating that the FFA is selective for faces. A
magnetoencephalography study found that examples of pareidolia, evoked an early
activation in the FFA, at a time and location similar to that evoked by faces,
whereas other common objects do not evoke such activation, supporting the
exclusiveness of FFA and its part in facial perception (Hadjikhani et al, 2009). Puce et al (1996) using
fMRI found that face stimuli evoked greater right hemispheric activation, with
characteristic patterns localised to FFS. Additional evidence for the
exclusiveness of FFA and facial evidence originates from (Tong et al., 2000), who discovered
that activation of the FFA also appears for faces of cats, cartoons, as well as
human faces, and insignificant for non-face stimuli. A case study of C.K who experienced
agnosia supports the theory of separate procedures in classifying faces, items
and places etc. He experienced tremendous trouble with simple object
recognition, also body parts, but perfumed well at recognising faces, providing
evidence that the FFA is specialised for processing faces in a normal
orientation. Interestingly, it is found that there is stronger activity in the
FFA when a person sees a familiar face as opposed to an unfamiliar one (Weibert
& Andrews 2015).
