In the large theoretical context of hierarchical organization of thinking as a form of cognition the gaps in psychological knowledge are presented. The basic source of this gaps is the tendency to analyse thinking as the consciously regulated, and step by step controlled mental activity. In this framework a little attention was concentrated on the unconscious processing and computational nature of thinking or its relation to basic cognitive processes. For this reason the main gaps in psychological knowledge are dealing with this area of understanding the mechanisms of thinking. The basic form of thinking (intuition, fantasy, opening and closing the conceptual structures) are described in the context of hierarchical organization of this process.
