The study highlights the structures and mental operations that are involved in the resolvent process, as well as the differences revealed by the research in this field regarding the manner of analysis and of organisation that differ from competent persons to the novice ones. In the processing of the assimilated information there are put into function by the subject, in succession, cognitive operations of thinking, memory, representation, that generate certain affective states and positive or negative emotional attitudes. In studying the architecture and the functioning of the human cognitive system we must start from the hypothesis that says that learning through training (in the educational process) means the transformation of the rational organisation of the knowledge that has to be learnt into a functional organisation, a transformation that is made through problem solving. Through rational organisation we understand the accessibility of the knowledge that will be passed on to the students, based on the compliance of the principles, the exigencies, psychological criteria and pedagogical norms.
Key words: information processing, psychological matrix, metacognition, formation profile
