Perception is the response to individual properties of things that act directly on the sense organs (e.g., colors, sounds, smells, etc.). Perception is the response to the individual parts and properties of things that act on our sense organs as a whole, based on sensation. Human beings acquire information about their surroundings from external stimuli through perception, which is not a passive process of receiving, but an active, positive and selective process. Sensory development begins in the fetus, with the mother’s voice and strong external light stimuli causing the fetus to respond; perceptual development begins after birth and develops rapidly within the first few years, with the majority of basic perceptual skills completed in infancy and early childhood. Early education can be used to promote perceptual development. Perceptual development is mainly in the following areas: 1. Vision (1) At the age of 1 month, infants can see objects within 15-30 cm in front of them and can look at them. At 2 months of age, the infant’s visual concentration becomes more and more obvious, and the infant likes to look at moving objects and familiar adult faces. 2 months later, the infant starts to adjust the visual focus according to the different distances of objects, and at 4 months of age, the infant is able to focus on near and far targets. Newborns open their eyes when they are awake, as long as the light is not too strong, and they maintain a controlled and careful search of their environment in the dark. (2) The newborn’s visual ability to observe and recognize complex shapes is about 1/30 of that of a normal adult, and this ability will improve greatly in the next 6 months, and is close to that of an adult by 6 months of age. 2. Hearing (1) In terms of hearing, infants’ hearing has improved greatly after the full moon, and they can respond to adult speech sounds. At the age of 2 months, infants like to listen to adults talking to them, and can show pleasant emotions and listen to soft music quietly. 3 months later, after hearing a sound, they can turn their heads to the sound source, and this response can be used to check the infant’s hearing ability. When hearing an adult speak to him, he will make a babbling sound or smile in response. 3. Taste When the baby is still in the mother’s tummy, their sense of taste is progressing day by day. The fetus’ mouth begins to develop in the second month, and at 4 months in the mother’s tummy, the taste buds on the fetus’ tongue are fully developed and can taste the amniotic fluid with relish. The nerve bundle of taste is myelinated at 7-8 months of age, so the infant’s sense of taste is well developed by the time of birth. Experiments have confirmed that infants have the ability to taste on the second day of life, and within one month will be able to identify sour and sweet tastes. 4.Sense of smell Sense of smell: in the fetus 7-8 months when the olfactory organs are relatively mature, newborns are born that has a sense of smell response, the baby’s sense of smell level is also very high, according to the taste of mother’s milk, to find the mother’s nipple, and will express aversion to irritating odors. 5, tactile newborn baby’s sense of touch is keen, like soft clothes, diapers, but also like the mother’s gentle touch. After 4-5 months of age, babies develop visual and tactile coordination, they can consciously reach objects and explore the outside world through touch.
