This paper presents results concerning the observation process modelling in the framework of cognition processes which belong to a new pattern of human knowledge. The cultural origin of the patterns is analyzed in terms of philosophical, psychological and linguistic points of view. A scenario concerning a robot integrated in a cognitive system is given in order to test the theoretical approaches. The definitions of signatures and of signature classes are given as one of the first steps in an alternative modelling approach to the observation process. An example that deals with the observation process modelling is offered.
