ABOUT THE FEATURES OF CRIMINALISTIC RESEARCH OF FACTORS AFFECTING HANDWRITING CHANGES

Abstract

The article highlights the current topic of sustainability of handwriting features under the influence of physiological aging. The focus is on the fact that the study of actual age-specific changes in human mobility in old and old age presents significant difficulties, especially when studying changes in motor functions in the elderly. This is due to the fact that physiological old age is a fairly rare phenomenon and in most cases, when researching the motor sphere of people of old age have to deal with complex interweaving, such as real age changes, as well as motor abnormalities resulting from a number of diseases that accompany aging. The issue of the impact of age-related changes in motor functions of a person in the elderly and senile age was considered, taking into account the distribution into three age groups of people older than 55 years. This was analysed and presented in an article on the sustainability of common features in signatures of older persons. The necessity of developing a structured methodology for the study of signatures performed by older and older persons in accordance with the state standards for the registration of its results was determined, which would correspond to the level of modern scientific developments. Key words: handwriting, handwriting research, motor functions, elderly and senile persons, physiological aging, variability, confounding factor, age group.
