This work presents a formalized description of information and communicative interac- tions of individuals on the basis of the communicative field （CF） method. It also contains explication of the possibility to create model of information and communication inter- actions, which is able to illustrate both interactions between two and more individuals. Methods and approaches which are suggested in this paper can correctly simulate the processes of distortion and generation of information images （IIs） with information and communication social interaction. Expansion and addition of IIs theory in terms of the transmission of information between individuals allows us to speak about the space of IIs. This space helps to explain a number of characteristic phenomena of human thinking.
