Intelligence Theory

"Minds differ still more than faces"

-Voltaire

The observation that “individuals differ from one another in their ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, to overcome obstacles by taking thought” (Neisser et al., 1996, p.77) resulted in the concept of human intelligence.

IAP and MindHub™ have expertise in theories of human intelligence and the application of psychological measurement methods to the development and interpretation of applied intelligence and academic tests.  We have conducted research and written extensively about the Cattell-Horn-Carroll (CHC) Theory of Cognitive Abilities

IQCA number of special research reports, briefs, on-line SlideShare Power Point presentations, and web-based Mind Map resources are available for download or for on-line web page viewing at the MindHub™ Special Reports and Publications section.  Visit IQ’s Corner for new reports. Intelligent Insights on Intelligence Tests and Theories (aka., IQ’s Corner) is the primary dissemination vehicle for research reports and contemporary updates on intelligence theory and research.
