Do you catch yourself saying "I'm getting old" more than you'd like to admit? Turns out, that habit might be doing more damage than you think. Psychologist Becca Levy of Yale has spent decades studying how our aging mindset — the beliefs we hold about what getting older actually means — shapes how we physically and cognitively age. In a study following more than 11,000 older Americans over twelve years, nearly half showed improvement in either cognitive or physical function, a story that gets completely buried when you only look at averages. Her earlier research found that people with a positive aging mindset lived 7.5 years longer on average than those with negative views — a bigger effect than the difference between having high or normal cholesterol. The mechanism behind this is a process called stereotype embodiment: the cultural messages we absorb about old age become self-fulfilling prophecies through three pathways — psychological, behavioral, and physiological. That last one involves chronic stress and elevated cortisol levels that, over time, actually shrink the hippocampus and accelerate biological aging. I also look at Ellen Langer's famous Counterclockwise study, one of psychology's most striking demonstrations of the mind-body connection, and what the concept of neuroplasticity tells us about our capacity for growth at any age. Plus, I talk honestly about my own complicated feelings about getting older — and what the research suggests we can actually do about them.

Why do some people remember things effortlessly while others repeat information over and over and still forget it? In this episode, Michael looks at what research on actors reveals about how memory really works. Drawing on studies by psychologists Helga and Tony Noice and the remarkable story of John Basinger — who memorized all 10,565 lines of Milton's Paradise Lost starting at age 58 — we look at why understanding something beats repeating it every time. If you're a student, a performer, or just someone who wishes they could remember things better, this episode will change how you think about learning.

In this episode of The Psych Files, I explore anthropomorphism—our tendency to attribute human characteristics to non-human entities—drawing from Justin Gregg's new book "Humanish." I discuss both helpful and harmful examples of anthropomorphism, from Soviet dolphin-assisted births to Japanese raccoon imports inspired by anime, and explain how this connects to Theory of Mind, our ability to attribute mental states to others. Gregg, an expert on animal cognition, argues that anthropomorphism isn't necessarily bad if used reflectively, citing Jane Goodall's approach of using intuition as a research starting point rather than proof. I examine surprising findings about animal cognition, particularly in reptiles like crocodiles who display play and social relationships, and discuss the important distinction between biological consciousness in animals and non-conscious AI processing. The episode addresses the fundamental question of animal consciousness and Gregg's precautionary approach: when uncertain about whether animals can suffer, we should assume they can rather than risk causing harm. I also talk about the latest research on the use of puzzles and their effect on dementia.
