Abstract thinking involves seeing concepts and ideas beyond concrete objects, allowing one to understand complex non-physical aspects of the world. It is used for higher-order skills like problem solving, understanding concepts, and creating art. People who think abstractly are often good at intelligence tests, solving complex problems, and divergent thinking. Characteristics of abstract thinking include conceptualization, symbolic representation, imagination, problem solving, language skills, and adaptability. Abstract thinking can be improved through activities like improvisation, puzzles, modeling, and exploring figurative language.
