Аннотация:The article reflects the results of theoretical and applied research in the field in related fields: neurophysiology, neuropsychology and neuropedagogy, which substantiate the idea of the cognitive nature of conflict behavior of a junior schoolchild as a synthetic phenomenon. The European Union, the US Congress, and the decade of brain research announced the last decade of the twentieth century. Neurocognitive technologies are firmly connected with the scientific picture of the future world order. In Russia in recent decades, research in the field of cognitive science has received a new impetus for development. The new ideas are received by the ideas of great physiologists, physicians, philosophers and psychologists of the past. According to Russian scientists, for the sciences of the twenty-first century, brain research begins to play a unifying role, as well as, for example, for the sciences of the last century, the study of heredity role, as well as, for example, for the sciences of the last century, the study of heredity.The discovery of the essential characteristics of DNA has linked many areas of knowledge such as neuroscience, microbiology, and immunology. Around the brain research, both social and social sciences are synthesized, new pedagogical, psychological and medical technologies are being developed. In the younger school age, the cortex of the cerebral hemispheres is maturing and intraocular interaction is improved, on the basis of which purposeful behavior is formed, the individual dynamics of mental development is determined. However, the most important, specifically human parts of the brain, responsible for programming, regulation and control of complex forms of mental activity, have not yet completed their formation in children of this age, so that the regulatory and inhibitory effect of the cortex on subcortical structures is insufficient. Imperfection of the regulating function of the cortex is manifested in peculiarities of behavior, organization of activity and emotional sphere peculiar to children of this age: younger schoolchildren are not capable of long-term concentration, are easily excitable, conflictual, and aggressive.
