In this episode of Cracking the Shell on Psychological Science, we sit down with Dr. Elizabeth Redcay to explore how studying real‑time interaction is reshaping what we know about the social brain and autism.

We dive into second‑person neuroscience, brain‑to‑brain synchrony, and why measuring social cognition in isolation can miss what actually matters in everyday life. The conversation also unpacks emerging research showing that autism is not a single spectrum, but may involve distinct subgroups with different behavioral, neural, and genetic profiles—raising important questions about how we study, diagnose, and support autistic individuals.

Relationships are an important part of the human experience, and especially for kids. In this episode, we dive into the role of relationships in early childhood education with Dr. Jude Cassidy. Jude shares insights from her decades of research on parent-child relationships and how her newest research taking place in schools throughout three counties in Maryland aims to create a new approach to early childhood education.

Do violent video games turn people violent? After forty years of research, dozens of meta-analyses, and even a Supreme Court case, the debate still won’t die. In this episode of Cracking the Shell on Psychological Science, Mike and Joey trace the controversy from Mortal Kombat and the birth of the ESRB to today’s competing meta-analyses. They unpack key critiques—how “aggression” is measured, publication bias, and confounds—and explain why many findings are small but consistent. Finally, they ask the real-world question: if effects exist, do they matter for policy?
