"Cognitive-Experiential Self-Theory (CEST) is a dual-process model of perception developed by Seymour Epstein. CEST is based around the idea that people operate using two separate systems for information processing: analytical-rational and intuitive-experiential. The analytical-rational system is deliberate, slow, and logical. The intuitive-experiential system is fast, automatic, and emotionally driven. These are independent systems that operate in parallel and interact to produce behavior and conscious thought. There have been other dual-process theories in the past. Shelly Chaiken's heuristic-systematic model, Carl Jung's distinction between thinking and feeling, and John Bargh's theory on automatic vs. non-automatic processing all have similar components to CEST.

The Neojungian Model uses the dual-process model of dividing between state 1 and state 2, where state 1 gives most energy.
