The social environment of early ontogenesis and the formation of research behavior in adulthood

219

Abstract

The influence of changes in the social environment in the nest from the 2nd to the 20th day of life on the manifestation of research behavior in adulthood has been studied. The study was performed on Wistar rats. To assess the motor activity used standard indicators of behavior in the “open field”. Analyzed the length of the path, the average speed of movement of the individual, the maximum speed of movement during the testing period, the time spent without visible movement, the number of exits to the central zone. It has been established that intact individuals, brought up together with sensory deprived siblings, change the severity of research behavior. It was revealed that the critical period during which a change in the social environment has a more significant influence on the formation of research behavior is the period from the 9th to the 20th day of life.
