A lively blend of personal narrative and popular science, Do I Know You? (Little, Brown Spark) is the story of one unusual mind’s attempt to understand itself — and a fascinating exploration of the remarkable breadth of human experience. It releases on June 25 but is available for pre-orders.

Author and science writer Sadie Dingfelder has always known that she’s a little quirky. But while she’s made some strange mistakes over the years, it’s not until she accosts a stranger in a grocery store (whom she thinks is her husband) that she realizes something is amiss.

With a mixture of curiosity and dread, Dingfelder starts contacting neuroscientists and lands herself in scores of studies. In the course of her nerdy midlife crisis, she discovers that she is emphatically not neurotypical. She has prosopagnosia (faceblindness), stereoblindness, aphantasia (an inability to create mental imagery)and a condition called severely deficient autobiographical memory.

As Dingfelder begins to see herself more clearly, she discovers a vast well of hidden neurodiversity in the world at large. There are so many different flavors of human consciousness, and most of us just assume that ours is the norm. Can you visualize? Do you have an inner monologue? Are you always 100 percent sure whether you know someone or not? If you can perform any of these mental feats, you may be surprised to learn that many people — including Dingfelder — can’t.

Dingfelder is a freelance science journalist, humor writer and Erma Bombeck Writing Workshop alum. Her writing has appeared in National Geographic, The Washington Post and Washingtonian magazine. A former staff reporter at the Washington Post Express, Dingfelder also served as senior science writer at the Monitor on Psychology magazine, covering new findings in neuroscience, cognitive science and ethology for members of the American Psychological Association.
