Alix Spiegel

Alix Spiegel has worked on NPR's Science Desk for ten years covering psychology and human behavior, and has reported on everything from what it's like to kill another person, to the psychology behind our use of function words like "and", "I", and "so." She began her career in 1995 as one of the founding producers of the public radio program This American Life. While there, Spiegel produced her first psychology story, which ultimately led to her focus on human behavior. It was a piece called 81 Words, and it examined the history behind the removal of homosexuality from the Diagnostic and Statistical Manual of Mental Disorders.

In January 2015, Spiegel joins NPR Science Reporter Lulu Miller to co-host Invisibilia, a new series from NPR about the unseen forces that control human behavior – our ideas, beliefs, assumptions, and thoughts. Invisibilia interweaves personal stories with fascinating psychological and brain science, in a way that ultimately makes you see your own life differently. Excerpts of the show will be featured on the NPR News programs Morning Edition and All Things Considered. The program will also be available as a podcast.

Over the course of her career in public radio, Spiegel has won many awards including a George Foster Peabody Award, a Livingston Award, an Alfred I. duPont-Columbia University Award, a Scripps Howard National Journalism Award, and a Robert F. Kennedy Journalism Award.

Originally from Baltimore, Maryland, Spiegel graduated from Oberlin College. Her work on human behavior has also appeared in The New Yorker magazine and The New York Times.

Patricia East is a developmental psychologist who began her career working at an OB-GYN clinic in California. Thursday mornings at the clinic were reserved for pregnant teens, and when East arrived the waiting room would be packed with them, chair after chair of pregnant adolescents.

It was in this waiting room, East explains, that she discovered her life's work — an accidental discovery that emerged from the small talk that staff at the clinic had with their young clients as they walked them back for checkups.

All day long we're surrounded by faces. We see them on the subway sitting two by two, pass them on the sidewalk as we make our way to work, then nod to them in the elevator.

But most of those faces don't tell us much about the emotional life of the person behind the face.

Were people happier in the 1950s than they are today? Or were they more frustrated, repressed and sad?

To find out, you'd have to compare the emotions of one generation to another. British anthropologists think they may have found the answer — embedded in literature.

Several years ago, more or less on a lark, a group of researchers from England used a computer program to analyze the emotional content of books from every year of the 20th century — close to a billion words in millions of books.

Ever since she was a small child, Samantha Grimaldo has had to carry her voice with her.

Grimaldo was born with a rare disorder, Perisylvian syndrome, which means that though she's physically capable in many ways, she's never been able to speak. Instead, she's used a device to speak. She types in what she wants to say, and the device says those words out loud. Her mother, Ruane Grimaldo, says that when Samantha was very young, the voice she used came in a heavy gray box.
