Under the Cortex

Two Maps in the Mind: How the Brain Stores What We Know About Others

How does your brain keep track of the people in your life—not just who they are, but where they are in relation to you and to each other? 

In this episode of Under the Cortex, Özge Gürcanlı Fischer-Baum talks with Robert Chavez from the University of Oregon about his new findings published in Psychological Science, the flagship journal of the Association for Psychological Science. His research shows that our brains rely on two separate systems to encode person-knowledge: one that maps others in the broader world (allocentric), and another that maps them in relation to ourselves (egocentric). 

Together, these systems help us organize social memory and navigate our relationships with others. Tune in to learn how the brain structures our social world—and why it matters.

Bridging Research and Editorial Vision: A Conversation with Arturo Hernandez

How do the roles of researcher and editor inform each other? What can this intersection tell us about the future of psychological science? 

 

In this episode of Under the Cortex, Arturo Hernandez, Professor of Psychology at the University of Houston and editor for Perspectives on Psychological Science, joins host Özge Gürcanlı Fischer Baum to reflect on the dynamic relationship between scientific discovery and scientific communication. Drawing from his research on bilingualism and brain plasticity, Hernandez shares how his experiences in the lab and at the editor’s desk have shaped his views on innovation, interdisciplinarity, and the evolving needs of the field.

Real-Time Research: How the Experience Sampling Method Is Changing Psychology

How do you design a study that captures human experience as it unfolds in real time? In this episode, Under the Cortex explores the Experience Sampling Method (ESM), a powerful approach for studying psychological processes. Host Özge Gürcanlı Fischer-Baum is joined by Jessica Fritz from Osnabruck University, and Marilyn Piccirillo from the Rutgers Addiction Research Center and Brain Health Institute, who are among the coauthors of a new article published in Advances in Methods and Practices in Psychological Science. The paper outlines ten key design and implementation considerations for ESM studies, helping researchers apply this method with clarity, rigor, and real-world relevance.

Why Do Emotions Hijack Our Decisions? The Neuroscience of Impulsivity

Why do some people struggle to control their actions when emotions run high? What happens in the brain when impulsive decisions take over? Why do some brains lose control under high arousal, while others stay composed? 

In this episode of Under the Cortex, host Özge Gürcanlı Fischer-Baum speaks with Matthew V. Elliott from the University of California at Berkeley. Elliott’s study published in APS’s journal Clinical Psychological Science explores the science of emotion-related impulsivity —a trait linked to psychiatric disorders, aggression, and even suicidality. Fischer Baum and Elliott discuss how a new model of brain function, the GANE model, helps explain why heightened physiological arousal makes it harder for some people to regulate their emotions, what norepinephrine does to “hotspot” brain regions, and what this means for mental health treatments.

Beyond Words: Why TalkBank is Crucial for Spoken Language Research

Most linguistic datasets focus on written text, but what about the way we actually speak? TalkBank, the world’s largest open-access repository of spoken language, is helping researchers understand everything from child development to dementia, bilingualism, and even classroom learning. 

In this episode of Under the Cortex, host Ozge Gurcanli Fischer Baum speaks with Brian MacWhinney from the Carnegie Mellon University, who recently published an article in APS’s journal Current Directions in Psychological Science. MacWhinney, the creator of TalkBank, highlights how spoken language research is transforming our understanding of psychology and communication. The conversation evolves into the discussion of the importance of open-access language databases, the role of AI in analyzing speech, and the future of spoken language research across cultures and disciplines.

Ensuring Research Validity: A Checklist for Stronger Science

Scientific credibility depends on valid research. But with growing concerns about replication failures and questionable research practices, how can scientists ensure their findings stand up to scrutiny? 

In this episode, Under the Cortex explores the VALID checklist, a newly developed tool that helps researchers systematically assess the quality of their studies. Özge Gürcanlı Fischer Baum speaks with Susanne Kerschbaumer from the University of Vienna and asks how the checklist offers tailored guidance for different types of research designs. Kerschbaumer explains how the study published in APS’s journal Advances in Methods and Practices in Psychological Science addresses this important issue. Together, they discuss why validity is more than just good methodology, how researchers can avoid common pitfalls, and what the future of scientific rigor looks like.

Young Minds, Smart Strategies: How Children Decide When to Use External Memory Aids

Do young children prefer to rely on their memory, or do they take the easier route and use external aids like lists and reminders? How do they decide when to put in the mental effort and when to lean on available tools? 

In this episode of Under the Cortex, host Özge Gürcanlı Fischer Baum teams up with Zsuzsa Kaldy from the University of Massachusetts Boston. They discuss Kaldy’s study published in APS’s journal Psychological Science addressing how children balance memory with external help. The conversation evolves into what these findings reveal about cognitive development, and cultural differences in learning.

Understanding Addiction: A General Liability or Unique Disorders?

Is there a single explanation that accounts for all addictive behaviors, or is the reality more complex? How can quantitative classification methods help uncover the nuances of substance dependence? 

In this episode, APS's Özge Gürcanlı Fischer Baum speaks with Ashley Watts from Vanderbilt University about her recent research article in Clinical Psychological Science. They discuss how simple explanations to addictive behavior – like the General Addiction Liability theory – may be appealing for a unified treatment approach, but a deeper, more quantitively rich dive into the data draws a more heterogenous picture. The paper argues that addiction follows a more diverse pattern, and the conversation highlights what this approach to addiction means for future research and for treatment strategies.

Addressing Selection Bias in Disparities Research

Psychological research often focuses on disparities, but how do the populations studied impact the reliability of findings? 

In this episode of Under the Cortex, Özge Gürcanlı Fischer Baum hosts Wen Wei Loh and Dongning Ren who recently published an article on this topic in APS’s journal Advances in Methods and Practices in Psychological Science. They discuss how non-representative samples can influence study conclusions and highlight solutions for strengthening study validity.

Beyond Focus: How Attention Shapes Learning Differently for Children and Adults

Children often surprise us with the details they remember—sometimes even better than adults! But what if their ability to learn comes not from focus, but from a broader, less selective attention? This episode unpacks research showing that while adults learn best when paying attention, children (ages 7-9) absorb information just as well, even when it’s irrelevant to their task. Could this be the secret behind their incredible learning abilities?  

In this episode of Under the Cortex, host Özge Gürcanlı Fischer Baum speaks with Marlie Tandoc from the University of Pennsylvania who recently published an article on learning and attention in APS’s journal Psychological Science. Together they discuss whether children’s weaker selective attention is a hidden strength by addressing findings on attention, memory, and childhood learning.
