Although there is ample research that indicates theimportance of FFA in facial recognition, there is more research that impliesthat the FFA is not limited to facial recognition, meaning facial recognitioncannot solely rely on the FFA to aid facial perception. Exploration intoinfants can provide opposing theory’s, in infants the FFA is underdeveloped, anddoes not completely develop until adolescence, however it is known thatchildren and babies show the ability to differentiate and recognise faces.Bushnell (2001) found that infants show a preference and obvious recognitionfor their mother’s face, and that very little exposure is required.
Babies asearly as 3 months’ old have shown the ability to distinguish between faces(Goldstein, 2013). Not only are they capable of distinguishing faces but show aclear preference for female faces (Quinn, et al 2002), providing anevolutionary aspect into the importance of facial perception, and shows babiesfocus on women for food. Although babies are capable of recognising anddifferentiating faces, a recent fMRI has found that there is no FFA in thebrain of infants between 4 and 6 months old (Deen et al, 2017). Consequently, itappears that the FFA as a single component into facial perception has itsflaws, there must be another neural structure that sub serves facial recognition.
However, is it important to note that the human brain has been studies far moreextensively than the infant brain, and it may not be that there is an absenceof FFA but it may be that it is not located in anatomicallyfamiliar area. Due to the factinfants are undergoing periods of neurogenesis (Johnson, 2001) this may make itmore difficult to distinguish the signal from a FFA. Furthermore, researchsuggests that it may be pointless to accept the presence of a prewired tendencyto orient toward the face geometry due to the fact there is a domain-generalbias toward conformations with more components in the upper than in the lowerhalf-top-heavy patterns. Suggesting faces do not hold a superior status innew-borns visual world (Viola Macchi, Turati and Simion, 2004).
