This chapter presents results concerning a new pattern of human knowledge. The new pattern is based on the experimentation of the causal relations. The cultural origin of the patterns is analyzed in terms of philosophical, psychological and linguistic aspects. The scenario concerning a robot integrated in a cognitive system is described. The definitions of signatures and of signature classes are given as one of the first steps in an alternative modeling approach to the observation process. © 2011 Scientific Assoc Infocomm.
