A Documentary Explores How We Talk to Ourselves

A researcher documents people's internal monologues

On any given day, millions of conversations reverberate through New York City. All these conversations are matched in number and complexity by much more elusive discourses. Even when speaking with others—and especially when alone—we continually talk to ourselves in our heads.

Psychologists have attempted to capture what they call self-talk or inner speech in the moment, asking people to stop what they are doing and write down their thoughts at random times. Others have relied on surveys or diaries. Andrew Irving, an anthropologist at the University of Manchester in England, recently recorded the inner dialogues of people walking in New York City. He approached strangers, asked them to wear a microphone headset attached to a digital recorder and speak their thoughts aloud as he followed closely behind with a camera.

“I was surprised by how many said ‘yes,’” Irving says—about 100 in all. By overlaying the recorded audio onto the videos, he has created portraits of individual consciousnesses on a particular day in New York.

Of course, people sometimes speak into the microphone as though trying to entertain someone else. And getting people's inner speech on tape captures only linguistic forms of thought, neglecting the kind of thinking that happens in images and scenes. Still, Irving's videos are permanent records of fleeting thoughts, of dynamic mental processes unfurling in real time.

In one video, a young woman named Meredith walks along Prince Street in downtown Manhattan. She briefly wonders if there is a Staples store nearby before reminiscing about a recent visit to her friend Joan, whom, we learn, has cancer. Meredith contemplates her friend's situation for the next two minutes, tearing up at the thought of “New York without Joan.” Abruptly, she notices a café where she used to sit and people watch, laments how it has changed and resumes her search for a Staples.

Meredith's meandering thoughts recall Clarissa Dalloway's roaming mind in Virginia Woolf's novel Mrs Dalloway. Woolf would likely have adored Irving's videos. She wanted to write about “an ordinary mind on an ordinary day.”

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
