Structure and development of the complex system of notions linked to the concept "tree"

The study described looks into the complex semantic system of notions relating to the concept "tree". The subjects were given a list of 14 notions differently related to the concept "tree". The study shows that in all the subjects (pupils of grades 7-9, university students, post-graduates) the system in question of logical and semantic correlations is poorly developed. It has been discovered that the content of the evolution of that complex system of notions is universal, is not determined by age or education and can be described in terms of the universal principles of systems development - those of differentiation and integration.
