Key Takeaways
- ✓Understanding ≠ Learning: Hearing and comprehending new information does not guarantee retention. The hippocampus selectively encodes experiences based on engagement level. To move information into long-term memory, actively talk about it — to yourself or others — shortly after encountering it, rather than assuming comprehension equals storage.
- ✓Verbal Goal Articulation: Speaking or writing about a specific goal — such as finishing a report by afternoon and naming the exact obstacle — measurably increases follow-through. STEM freshmen who wrote three reflective essays about their major choice persisted in that major at significantly higher rates two-and-a-half years later than peers who did not.
- ✓Emotion Labeling Quiets the Brain: Moving beyond vague descriptors like "upset" to precise emotion labels — scared, angry, disappointed — reduces limbic system activity, the brain region governing fight-or-flight responses. This neurological quieting enables more rational thinking and prevents reactive behavior during emotionally charged situations.
- ✓Conversation Over Brain Games for Dementia Prevention: Regular back-and-forth conversation is among the strongest behavioral protections against dementia, yet receives far less attention than commercial brain-training apps. Research does not support brain games as effective dementia prevention, whereas sustained social talking and listening builds measurable cognitive resilience, particularly for isolated older adults.
- ✓Rehearse High-Stakes Conversations: Practicing difficult conversations aloud — job interviews, partner conflicts, negotiations — improves outcomes even though the actual exchange never follows the script exactly. Rehearsal builds clarity of expression, reduces inflammatory phrasing, and prepares responses to likely pushback, functioning similarly to how athletes use deliberate practice before competition.
What It Covers
Cognitive scientist Maryellen MacDonald, author of *More Than Words*, explains how talking — defined broadly to include self-talk, writing, and signing — produces measurable cognitive benefits beyond communication, including sharper focus, better emotional regulation, stronger memory encoding, and reduced dementia risk when practiced deliberately.

Notable Moment
MacDonald reveals that companies recording customer service calls may be analyzing not just words but vocal tone and language patterns to predict purchasing behavior, political persuadability, and personality traits — capabilities most people assume protect their private internal states, which talking inadvertently exposes.
Episode Transcript
This is the Ten Percent Happier podcast. I'm Dan Harris. Hello, everybody. How we doing? Today, I'm talking to a cognitive scientist about how to harness something we all do every day. Talking. We're gonna cover how to use talking in order to prevent distraction, depression, dysregulation, dementia, and much more. Just to be clear from the jump here, and I already made a nod to this, but I wanna make it super clear. My guest is defining talking in a broad way, not just having conversations with other people, but also having conversations with yourself. In other words, self talk and also writing to yourself, which is another kind of self talk. So again, she's defining talking broadly. The she in question is Mary Ellen McDonald. She is the Donald P. Hayes Professor Emeritus of Psychology and Language Sciences at the University of Wisconsin Madison. She's a cognitive scientist with a focus on psycholinguistics, which is the study of how we comprehend, produce, and learn languages. She's also written a book, which is called More Than Words. In this conversation, we talk about the hidden benefits of talking, including, as I mentioned earlier, both self talk and writing. How talking helps focus attention and clarify your thinking. Why talking can help regulate your emotions and improve your decision making. Why talking is actually harder than listening. Why we shouldn't rush to finish other people's sentences. How deliberate talking can protect against dementia, why understanding something doesn't necessarily mean you've learned it, how talking about new information helps your brain remember it, why explaining things to other people deepens your own learning, and much more. Two things to say before we dive in. First, don't forget to check out my new ish meditation app, 10% with Dan Harris. We've got a growing body of guided meditations from teachers like Joseph Goldstein, seven a Salassy, and Jeff Warren. We also do these live video sessions every week where we meditate together and take your questions, and it's the place to get this podcast ad free. Second thing to say is if you wanna meditate with me in person, I've got two IRL events coming up. The first is on May 17. I'll be at the 92nd Street Y in New York City. I'll guide a meditation and then take your questions. Specifically, I'll focus on how meditation can be really helpful and not self indulgent in these fraught times. And then on October 16 through the eighteenth, I'll be doing a weekend event at the Omega Institute in Upstate New York. It's our annual meditation party event. I do it with seven a. Selassie and Jeff Warren, my two close friends. It's a full weekend. We teach a variety of meditation techniques over the weekend. We take your questions. We even throw a dance party. It's a great way to deepen your practice and to get to know other people who also meditate, which is a key part of the practice. …
