Dermatoglyphics test method is simple, non-invasive, not affected by various stages of human development, not interfered by the tester's physical health, physiology, cognitive degree and other factors at that time, which can predict early and provide reliable genetic information to a certain extent. Through the test, we can find super-long children as early as possible, so as to carry out targeted training and promote their success; For ordinary children, we can understand the scope of their intellectual potential, which is convenient for teaching students in accordance with their aptitude; In particular, finding children with mental retardation in time is of great significance to improving the quality of our population and promoting the growth of talents.
Kant, a famous German philosopher, once said: "Hands are the outer brain of human beings", and hands can reflect the skills and psychological activities of the brain. There are a large number of sensory nerve endings such as pressure, pain and temperature at the fingertips, which is also the most densely distributed part of dermatology. Human dermatoglyphics are highly specialized on the palm surface, which is closely related to subcutaneous tissue-bone joint-muscle-nerve. In embryology, dermatoglyphics and nervous system belong to ectoderm, which are formed and developed in the third month of embryo, and are regulated by genetic factors and central nervous system. Therefore, dermatoglyphics is the external manifestation of nervous system development, which is closely related to its higher nervous activity and types.
Although personality is influenced by genetic factors and reflected in dermatoglyphics, it is influenced by many factors and has plasticity. Through dermatoglyphic observation, we can quickly understand a person's personality and temperament type without damage, especially for teenagers, and provide necessary psychological counseling and guidance to adapt to various psychological problems in the growing period and the complex social relations and pressures faced by society, which is very beneficial to the healthy growth of teenagers and the improvement of psychological resilience, and has certain application prospects.
According to the theory of multiple intelligences, "the purpose of school education should be to develop multiple intelligences and help students find careers and hobbies suitable for their intelligent characteristics." Because in school education and teaching, it is very important for every student to find that he has at least one advantage.
Dermatoglyphics is related to IQ and belongs to polygenic inheritance. The correlation between them may be due to the differences and interactions between genomes and the interactions between genes and environmental factors. Dermatoglyphics of high IQ people are specific, so most scholars think that dermatoglyphics characteristics can be used as one of the auxiliary basis for selecting outstanding talents. 1823, Czech physicist and biologist Joannes Evangelista Purkinje began to study the protruding skin ridges on human palms and soles, and tried to systematize them to find out their further relationship with human beings.
Two articles by Professor Henry Faulds and Professor W.J Herschel were published in the journal Nature of 1880, and the method of fingerprint pinnacle was recommended as a method to distinguish human uniqueness.
Professor Francis Galton published his research in 1892, pointing out the genetic relationship between fingerprints and siblings, twins and generations, and summarizing its partial consistency among relatives.
From 65438 to 0902, Harris Hawthorne Wilder, an American scholar, laid a complete system foundation for dermatoglyphics in the study of morphology, genetics and interracial finger palmprint.
Professor Harold Cummins led the research in this field from 65438 to 0926, and put forward the proper term dermatoglyphics in the American Morphological Society. At this point, dermatoglyphics has officially become a subject in the field of professional research.
At the same time, Dr. Cummins found that the dermatoglyphics of cases with abnormal chromosomes or brains are different from those of ordinary people. When the embryo is at the age of 13 weeks, the dermatoglyphics of its hands and feet begin to develop and form, and the fine lines will continue to develop until the 24th week, which will remain unchanged for life. It is also related to the development of fetal brain (fetal brain cells are also formed from the central part at 15 weeks). This important discovery is also recorded in many writings and documents of Medical Genetics at home and abroad.
Then, Dr. Walker first calculated the dermatoglyphic index of 2 1- trisomy syndrome. After years of research by scientists, it is proved that "many patients with chromosome and brain abnormalities have abnormal dermatoglyphic texture patterns", and this standard is used as an important indicator to judge chromosome and brain abnormalities, with an accuracy rate of over 70%.
After years of comparative analysis and induction by medical experts and scientists, it is found that the cell values distributed in various regions of the brain can be obtained by dermatoglyphics sampling and calculation.
