System approach to the analysis of behavior of the person in system of social and economic activity

The article considers the methodological approach to the analysis of the relationship between behaviours in different living conditions and ways of reflection of the phenomenon of categorical apparatus of the concept of needs. It is proposed to discuss an extended range of terms describing various levels of human needs in the structure of life in modern society. It is postulated that human behavior is a complex structure of cognitive and motor responses directed to the implementation of a number of fundamental functions of the individual, the main ones are: - maintaining personal and organismic homeostasis, in the system of life; procedure aiming to change its own structural organization adequate to the challenges of the environment and professional activity. Behavior is regulated by physiological, social and cultural processes, using feedback mechanisms on the criterion of its performance (behavior notsatisfying the characteristic of the result or changes or dies its owner). The methodological approach that adequately represent (describe) and to explain these very complicated phenomena and integrate diverse knowledge in the theoretical design of the system. Professional (subject) activity is a complex structure of processes of different nature and direction, and if for example, we are studying the labor process, it can be represented and measured by numerous parameters: the duration, intensity, complexity, strength of individual functions, operational composition of motor acts, etc., but with the General criterion of its efficiency - the physiological cost of the work. And only with this approach and conditions, the categorical system needs to be linked to the processes generating them, and they organically fit into the structural-functional model of human behavior in the subject system (professional) activity.
