As we wrap up 2025, we are featuring some of our most important conversations, including this conversation about IQ, intelligence, and intelligence assessment. Emily Kircher-Morris welcomes 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 sprawling conversation, Emily and Jack talk about his insights on the evolution and misconceptions surrounding intelligence assessment. They discuss the history of intelligence testing, and the limitations and biases inherent in traditional methods. Dr. Naglieri describes the experiences that led him to question the validity of verbal-based intelligence tests, and ultimately inspired his development of nonverbal assessment tools. 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.

Dr. Jack A. Naglieri, Ph.D., is Emeritus Professor at George Mason University and Senior Research Scientist at the Devereux Center for Resilient Children. His main interest is the development of psychological and educational tests and the implications these approaches have for accurate and equitable assessment.
He has published about 25 books, 50 tests and rating scales, and approximately 300 research papers. Jack is the author of tests used for identification of gifted students, including the Naglieri Nonverbal Ability Test. He partnered with Dina Brulles and Kim Lansdowne to coauthor the Naglieri Tests of General Ability Verbal, Quantitative and Nonverbal, and the book, Understanding and Using the Naglieri General Ability Tests: A Call to Equity in Gifted Education (Brulles, Lansdowne & Naglieri, 2022).
Dr. Naglieri has received many awards for his extensive research program that includes scholarly research, books, and psychological tests with an emphasis on uniting sound theory with equitable scientific practice.

Emily Kircher-Morris and Dr. William Dodson have a conversation about the complexities of ADHD, in which they discuss emotional dysregulation, Rejection Sensitivity Dysphoria (RSD), and social anxiety. They talk about how RSD manifests in ADHDers, and how we can distinguish it from social anxiety. They also explore the impact of childhood experiences, the vital role of relationships, and the need for updated diagnostic criteria. This conversation was taken from a two-part series earlier in 2025.
TAKEAWAYS
Emotional dysregulation is often overlooked in ADHD diagnoses.
RSD is a specific condition affecting many with ADHD; the pain can be both emotional and physical, leading to significant life impairments.
Social anxiety is anticipatory, while rejection sensitivity is reactive; they can coexist but are distinct.
Childhood experiences can exacerbate RSD but are not the sole cause.
Medication, alongside sleep, nutrition, structure, and routine, plays a vital role in emotional regulation.
Mood disorders can manifest independently of external events, and a significant percentage of individuals with ADHD have coexisting psychiatric diagnoses.
Understanding RSD is essential for clinicians, and psychoeducation is key to self-advocacy.
Here's the research project Emily mentions in her closing thoughts.
Dr. Bill Dodson is a board-certified adult psychiatrist who has specialized in adults with Attention Deficit/Hyperactivity Disorder for the last 27 years.
In recognition of his clinical contributions to the field of ADHD he was named a Life Fellow of the APA in 2012. He was the 2006 recipient of the national Maxwell J. Schleifer Award for Distinguished Service to Persons with Disabilities.
His contributions to the field of ADHD include:
The only currently available methodology for the fine-tuning of ADHD medications.
The concept of Rejection Sensitivity Dysphoria and its treatment with medications.
The first non-behavioral theory of what ADHD is and how it can be treated successfully with an emphasis on what goes right rather than what goes wrong.

Emily Kircher-Morris is joined by Tim Villegas, the Director of Communications at the Maryland Coalition for Inclusive Education (MCIE) and the founder and host of the Think Inclusive Podcast, to discuss the concept of inclusion in education.

School should be a place where everyone belongs, regardless of their needs.
Being fair means providing everyone with what they need, not just the same thing.
Community plays a crucial role in fostering inclusion in schools.
Inclusion is not just about placing students in general education settings; it's about creating supportive environments.
Schools should aim to be more like real life, accommodating all learners.
