There has been long-standing debate regarding the mechanisms underlying development in face recognition ability. Theories form the face-specific view argues that the immaturities in children’s face recognition skills is that children and adults use different face processing modes. These theories include featural-configural processing theory, internal-external processing theory, and multi-dimensional space theory.The other theroy argues that children can process faces like adults at an early age,and overall improvement beyond that age is due entirely to the development of general cognitive factors.Based on a review of these two different viewpionts,five suggestions on future researches were proposed.
