As part of our two-part series, we are speaking with Dr. Jack Naglieri, an emeritus professor at George Mason University and senior research scientist at the Devereux Center for Resilient Children. Dr. Naglieri is renowned for his work in intelligence testing and the development of the Naglieri Nonverbal Ability Test.

In this episode, part one of the interview, he and Emily talk about his insights on the evolution and misconceptions surrounding intelligence assessment. They delve into the history of intelligence testing, highlighting the limitations and biases inherent in traditional methods. He describes the experiences that led him to question the validity of verbal-based intelligence tests, and ultimately inspired his development of nonverbal assessment tools. Dr. Naglieri describes how and why his tests aim to measure thinking rather than knowing, and how it provides a more equitable approach to assessing intelligence.

They discuss the PASS theory of intelligence, and how it forms the foundation of the Cognitive Assessment System (CAS), a tool designed to measure these processes and offer a nuanced profile of an individual's cognitive strengths and weaknesses.

They cover much more as well, it’s an enlightening conversation about how we measure intelligence. Look for part two of the chat in episode 230. Feel free to download a free copy of PASS Theory of Intelligence and the CAS2.
