The Cattell-Horn-Carroll (CHC) Theory

The Cattell-Horn-Carroll (CHC) Theory is a comprehensive framework for understanding human intelligence. It suggests that intelligence consists of various broad and narrow skills, such as reasoning, memory, and language abilities. Broad abilities include areas like fluid reasoning (problem-solving in new situations) and crystallized knowledge (accumulated learning). These skills are built from more specific, underlying abilities. The CHC model helps psychologists assess and understand different aspects of intelligence, providing a detailed map of cognitive strengths and weaknesses. It’s widely used in educational, clinical, and research settings to better understand individual cognitive profiles.
