This document discusses different types of thinking including autistic thinking and realistic thinking. Autistic thinking involves daydreaming, free association, and word association and is not connected to reality. Realistic thinking is controlled, constructive, factual, and based on reasoning. The document also discusses problem solving, creative thinking, reasoning, heuristics, algorithms, syllogisms, and means-end analysis as cognitive processes. Key types of reasoning explored are inductive reasoning, which goes from observations to conclusions, and deductive reasoning, which uses general rules to derive specific conclusions.
