Figure 1: Tripartite model of higher cognitive functions. Hierarchical structure of the three cognitive levels and their basic functions are shown. Autonomous mind is phylogenetically the eldest component of the cognitive apparatus. It operates in subconscious state and assures survival by speed, robustness and reliability of responses to the cues provided by the environment. The algorithmic level requires conscious attention; it may override System 1, facilitate data processing and formulate novel responses by developing adaptable cognitive heuristics applicable in specific settings. By decoupling of the subordinate processes it allows “off-line” processes performed by the reflective mind associated with passing judgments, decision making, associative thinking and other.
