Abstract: Pain perception in infants is of great significance to the growth and development of infants, which has aroused increasing interests of researchers. Pain is essentially an unpleasant sensory and emotional experience that is acquired through early injury-related experiences. From the perspective of psychology, it is meaningful to systematically demonstrate the effects of pain perception on infant growth and development on the basis of understanding the concept of infant pain, its neurophysiological mechanism and evaluation tools. Subsequent research should continue to improve the measurement tools of pain perception in infants, and to investigate the differences in pain responses among different cultures and groups.
