Cattell-Horn-Carroll theory of intelligence

The Cattell-Horn-Carroll (CHC) theory of intelligence is a comprehensive model that explains human cognitive abilities. It categorizes intelligence into broad core areas, such as reasoning, memory, and processing speed, and further divides these into specific skills like vocabulary or visual recognition. Essentially, it suggests that intelligence is multi-faceted, with various interrelated abilities working together. This framework helps psychologists assess and understand individual strengths and weaknesses across different mental skills, providing a detailed picture of a person’s cognitive profile.
