As artificial intelligence becomes increasingly integrated into our lives, the way machines “think” is beginning to mirror how humans make decisions. The recent rise of large language models (LLMs) has brought renewed attention to a style of intelligence that resembles what psychologists call “thinking fast”—quick, intuitive, and context-driven responses. But human intelligence also relies on a slower, more deliberate system of reasoning—”thinking slow”—which allows for reflection, planning, and logical analysis.
In "Machines Thinking Fast and Slow," Dr. Brent Venable explores how insights from dual-system theories of human cognition can help us build smarter, more adaptable AI. Drawing on examples from AI agents performing complex tasks, Dr. Venable highlights how combining fast, data-driven neural approaches with slower, symbolic reasoning leads to more robust performance. This dual-systems perspective not only provides a promising path for integrating symbolic and neural methods in AI, but also offers a framework for understanding the next generation of intelligent systems—machines that can reason, reflect, and react, all in the flow of thought.
Dr. Brent Venable's research sits at the intersection of AI-based preference reasoning and cognitive modeling of human decision making, with the goal of designing intelligent systems that are both adaptive and human-aware. Her work focuses on developing automated models of preference to support decision-making in applications such as recommender systems, human-machine teaming, and behavioral modeling. More recently, she has explored the ethical implications of AI technologies and their potential for advancing social good. She is the co-author of two books and has published more than 100 peer-reviewed articles in leading AI journals and conferences. She collaborates with a number of premier research institutions, including NASA Ames, IBM Research, and NICTA, and her work has been supported by agencies such as NASA, ONR, ARL, NIH, NSF, the Gulf of Mexico Research Initiative, and the Future of Life Institute. Brent graduated Magna Cum Laude in Pure Mathematics from the University of Padova, Italy, and earned her Ph.D. in Computer Science and Artificial Intelligence with a dissertation on automatically learning preferences over schedules, developed at NASA Ames in support of the Mars Rovers Spirit and Opportunity. She is currently a Senior Research Scientist at the Florida Institute for Human and Machine Cognition (IHMC) and serves as Director of the IHMC–University of West Florida Ph.D. program in Intelligent Systems and Robotics. She is also a Professor of Computer Science at the University of West Florida. Previously, she held a joint appointment with Tulane University, where she joined as an Associate Professor in 2012 and was promoted to Professor in 2018. Before moving to the U.S., she was a tenured Assistant Professor of Computer Science at the University of Padova.

![Episode 194: Tommy Wood discusses how to future-proof the adult brain
Neuroscientist and frequent STEM-Talk guest Dr. Tommy Wood rejoins us today for part two of our interview about Tommy’s book that is fresh off the press and now available in bookstores and Amazon, “The Stimulated Mind: Future-Proof Your Brain from Dementia and Stay Sharp at Any Age.” (https://www.penguinrandomhouse.com/books/751292/the-stimulated-mind-by-dr-tommy-wood/)
Tommy is an Associate Professor of Pediatrics and Neuroscience at the University of Washington, where his laboratory focuses on brain health across human lifespan. Tommy is a colleague and good friend who also is a Visiting Research Scientist here at IHMC.
In part one of our interview with Tommy, episode 193, we discussed his mission to dispel the myth that the brain is doomed to decline with age. Tommy gave us a fascinating history of neuroscience and how researchers go about studying the brain. Tommy also talked about what is holding us back in terms of addressing an ever-increasing burden of cognitive and mental health disorders that we are experiencing not only here in the U.S., but also around the world.
Today, Tommy shares science-backed strategies to help people future-proof their brains. We talk about the importance of diet and exercise in terms of brain health as well as the importance of stimulating and challenging our brains throughout our lifespans.
Tommy has a bachelor’s degree in biochemistry from the University of Cambridge, a medical degree from the University of Oxford, and a Ph.D. in Physiology and Neuroscience from the University of Oslo.

[00:03:55 Dawn welcomes Tommy back for part two of his interview by asking him about his recent trip to the UK.
[00:04:32] Dawn recaps where we left off with Tommy in part one of our interview, explaining that when we last spoke with Tommy about his book, The Stimulated Mind, we focused on dispelling myths about the adult brain, in particular the idea that the adult brain is fixed.
[00:05:22] Ken asks Tommy about advice his father offered when Tommy got accepted into the University of Cambridge.
[00:08:03] As a follow-up, Dawn asks if it’s fair to say that when Tommy first started working with patients, what he learned in textbooks and classrooms didn’t necessarily translate perfectly into the real world and that there is no one-size-fits-all fix.
[00:11:54] Ken asks Tommy to expand on what he wrote in his book about the fact that while science can give us a framework for understanding the world, we are always only one experiment or one well-phrased question away from having to completely rethink everything.
[00:16:44] Dawn launches into talking about what people can do to future-proof their brain, starting with diet. In the Nourish chapter of his book, Tommy seeks to help people see food as an opportunity for nourishment rather than a source of stress since there are so many conflicting messages about diet and healthy foods out there. Dawn asks Tommy if his opinion is that there is no one-size-fits-all diet?
[00:22:21] Dawn explains that what we eat has a direct effect on our long-term health and dementia risk, and within the literature a common theme that emerges regarding eating for brain health is maximizing nutrients. Dawn asks Tommy to talk about what this looks like.
[00:24:49] Dawn points out that people today are inundated with advice from health influencers in all directions. She asks Tommy to talk about his advice to tune out the noise and instead of chasing whatever supplement or super food that is currently in vogue, simply to focus on filling your diet with whole, nutrient dense foods.
[00:29:43] Ken explains that nutrients are sometimes hard to get in the diet, with somewhere between 15 and 25 percent of people in the U.S. and Europe having inadequate intakes of most B vitamins and even higher deficits in iron, magnesium, calcium, and vitamins C and E, with nutrient deficiencies differing by sex. Women on average are lower in B12, iron, iodine, and calcium, while men are typically lower in magnesium, zinc, and various B vitamins. Ken asks Tommy to give an overview of what these nutrients do in the brain that makes them so critical to cognitive function.
[00:35:51] Ken follows up on this discussion by moving on to the section in Tommy’s book titled “To Supplement or Not to Supplement” where he discusses the evidence of the benefits of targeted supplementation to fill in the nutrient gaps that exist in the diet. Ken asks Tommy to talk about this more in depth and maybe give a framework by which people can think about adding or not adding key nutrients via supplementation.
[00:41:21] Given the controversial reputation red meat has, Ken asks Tommy to weigh in on how he thinks people should think about red meat.
[00:46:26] Fish as well, Dawn explains, has become controversial, due to microplastics and mercury concerns. However, given the positive effects on cognitive health that fish consumption has, Dawn asks To...
