Children's aggressive behavior has always been one of the most headaches for parents, which not only directly causes friction and conflict between children, affects children's environmental adaptation and interpersonal ability, but also causes the tension of parent-child relationship and the impact of emotional support mechanism.

There are many reasons for children's aggressive behavior, such as personality characteristics, behavioral problems, environmental factors, etc., but for children before the age of six or even some primary schools, the tactile defense phenomenon caused by tactile dysfunction is the most important cause, and only by improving the function of the basic tactile system, other behavioral problems, personality traits, etc. Can also be significantly improved.
The tactile system of the human body can be roughly divided into two major systems, one is the primitive tactile system (anterolateral tactile system) (anterolateral tactile system) before the lateral mound system, and the other is the more advanced tactile system (posterior column medial lemniscal tactile system) after the column of the inner mound system. As the name suggests, the primitive haptic system is the oldest and most original haptic function, and in fact, it is also an innate instinct, a divine gift, an innate ability after birth.
The primitive tactile system is mainly responsible for feeling the "hot and cold", "itchy", "light touch" and other sensory stimuli closely related to survival (too cold will frostbite, overheating will burn, pain represents trauma, itch represents poisoning, light touch suggests the arrival of the threat), and the response of the primitive tactile system is also very primitive monotonous, only two reactions, either attack or escape (fight or flight), just like wild animals in the forest, when encountering a threat, it is either to stand up and attack, or to pull out the leg to escape.
On the contrary, advanced haptic systems are mainly developed by acquired learning and learning. Advanced haptic systems mainly transmit fine touch, vibration, haptic pressure, and proprioception and other sensory stimuli with a high degree of differentiation (fine touch is characterized by the location of the designated point of the exclusivable stimulus and the path of the tactile action; vibration and haptic pressure can feel extremely subtle differences; while the shape and body sense is like the "eye of the hand" like the fine area discernment, can be formed in the mind by groping for contours and forming a pattern in the mind to make the individual "see" something, which is the ultimate expression of fine proprioception).
The response of the advanced haptic system is also like its multiple ability to distinguish, there will be very different multiple reactions with subtle differences, such as the same stimulation of tapping the shoulder, but there will be different or even opposite interpretations and reactions depending on the situation and the different characters (just like if you pat your father's shoulder at home, it has the meaning of encouragement and comfort, but if you pat the shoulder of the case officer at the police station, it may imply warning and trouble; if it is a dark and windy night in the cemetery, no matter who is patted on the shoulder, That may feel completely different again)."
After birth, the primitive tactile system will gradually reduce the original extremely sensitive and extreme tactile response of young children to an appropriate degree as the frequency and degree of tactile stimulation (such as stimulation of food and tablespoons and other food utensils during feeding, stimulation such as skin towel soap when helping children bathe and clean, cuddling and pinching combs and other stimuli when interacting with children), which will gradually reduce the original extremely sensitive and extreme tactile response of young children to an appropriate degree, and this process of desensitization is extremely natural and continuous, and the form of desensitization stimuli will also be passively stimulated. Slowly transforming into active exploration comes from my excitement.
On the contrary, as children grow up, the types and forms of tactile stimuli they can access are becoming more and more diverse, which will promote the continuous learning and development of advanced tactile systems, so that their original ability to distinguish will become more and more refined and meticulous.
For example, when exposed to wood stimuli, one can learn to distinguish between wood and non-wood; if one is exposed to paper stimuli, in addition to distinguishing between paper and non-paper, wood and non-wood stimuli, it is also possible to distinguish neither paper nor wood— just as the more types of tactile stimuli a child is exposed to, the more tactile discrimination will develop more vigorously, precisely and diligently at a multiplier rate.
There are many causes of haptic defense
Children who are born by caesarean section are the most likely to cause "tactile defense", and the lack of uterine contraction and the process of vaginal squeezing will directly lead to the child's tactile defense. Non-breastfeeding after birth may also cause inadequate tactile stimulation in children.
In addition, the environment in which the child lives is too "safe", and parents do not let the child touch this, say "dirty", and do not let the child touch that, saying "unhygienic". The protection of the child is too thoughtful, the child loses the opportunity of tactile stimulation, and does not give the child enough tactile stimulation during the critical period when the child needs tactile stimulation, which may lead to the child's "tactile defense".
There are many parents because the work is too busy, there is no time to play with the child, but also lack of physical contact with the child, too early to let the child sleep independently, will make the child's tactile stimulation insufficient, there is a performance of "tactile defense".
Early attention, early correction
Children exhibit some characteristics of "tactile defense", and parents do not have to be nervous.
The child of "tactile defense" will not affect her \(his\) normal life, but we need to pay special attention. Because if you pay attention to early correction at a young age and increase the chance and time of tactile stimulation, you will avoid more symptoms of tactile defense, and you will avoid some behaviors that have an impact on the child's social development, which in turn will affect the child's normal learning, interpersonal communication and other abilities.
