What does the CHC theory stand for in terms of cognitive ability?

The CHC theory stands for Cattell-Horn-Carroll, which is a comprehensive model of human cognitive abilities. This theory integrates and builds upon the work of psychologists Raymond Cattell, John Horn, and John Carroll, who each contributed to the understanding of intelligence in different ways.

Cattell identified two broad types of intelligence: fluid intelligence (the ability to solve novel problems) and crystallized intelligence (knowledge gained from experience). Horn expanded on Cattell’s work by adding the importance of various specific abilities, and Carroll further synthesized their ideas into a three-stratum model. This model categorizes cognitive abilities into a hierarchy, with general intelligence at the top (the g factor), followed by broad abilities, and then narrow abilities.

Understanding the CHC theory is crucial in the field of psychology, especially when assessing cognitive abilities in educational settings. It acknowledges a wide array of cognitive skills beyond what traditional intelligence tests may measure, promoting a more nuanced view of student potential and areas for development.
