Vanishing Perception With Magic

Master magician Prakash Puru took out a silver coin and held it with one hand. He snapped his fingers. In seconds the coin disappeared, only to reappear later by his elbow. Over and over again the coin vanished, much to the delight of a packed audience at the Rubin Museum of Art in NYC.

Puru was invited to discuss the ways magicians manipulate perception to create illusions with neuroscientist Tony Ro. The Brainwave Series program, “Why Magicians are Master Manipulators,” focused on the neuroscience of perception and how its principles can be used to create magic.

How to Perceive Without Sight

How is it that we construct our reality? What is it we think we know, and what do we actually know? These are questions that led Columbia University neuroscientist Jacqueline Gottlieb to a career studying attention, decision-making, and curiosity. And at Saturday’s Brainwave event at the Rubin Museum of Art in NYC, we learned how these questions were addressed by someone who lost his sight at age 25.

At “How to Perceive Without Sight,” Gottlieb spoke with entrepreneur Isaac Lidsky, who was diagnosed with retinitis pigmentosa, a degenerative disease of the retina, at age 12. Prior to losing his vision, he already had achieved status as a child actor, lawyer, Supreme Court clerk, and a successful business owner. But when he lost his sight in early adulthood, he had to overcome depression and learn to shift his attention to his remaining senses to navigate the world around him.

“It was an eye-opening process,” quipped Lidsky, who came to realize that his other senses provided him with “phenomenal” information. Rather than passively observing the world through sight as before, he now had to make a conscious effort to pay more attention to that other information.

Listen to Your Ingredients

“For a marinara like this, the San Marzano tomato, grown on the hills of the volcano above Naples, Vesuvius, is about the best.”

That was just part of the advice offered up by Lidia Bastianich, who was recently featured at the Rubin Museum during the museum’s Brainwave series. The Italian-born American chef and psychobiologist Gary Beauchamp, PhD, explored the link between the brain and cooking in “What’s the Secret to a Great Home-Made Sauce.”

Tickets are now on sale to the public for the Rubin Museum of Art’s 2017 Brainwave series on perception. Based in New York City, this series, which runs from January 25 – April 29, pairs scientists and artists, celebrities, and other personalities for talks on topics related to the program theme.

As described on the Rubin Museum’s website:

“The tenth season of Brainwave will help us better understand the limits of our perception, allowing us to change our brains, unshackle ourselves from the past, and unleash creativity, growth, and inspiration.”

Facial Cues and the Brain

As human beings, we can tend to be a little judgmental–sometimes without even realizing it. When we first meet someone, our brains are busy processing facial features, body language, personality traits, etc., within milliseconds of just saying “hello.” So what characteristics make us assume certain things about people we just meet, and can these unconscious first impressions really change the way we perceive someone?

Expanding on this topic, neuroscientist Jon Freeman, Ph.D., spoke to a room crowded with eager listeners as the featured guest in the latest event from the Secret Science Club. As director of the Social Cognitive & Neural Sciences lab at New York University, Freeman devotes all of his research to understanding “split-second social perception”—that is, how our brains use subtle facial cues, personality traits, and emotion to instantly categorize others into social groups. With the help of brain imaging technology (fMRI), electrophysiology (EEG and ERP), and real-time behavioral techniques, Freeman is able to study activity within the brain in hopes of learning more about the phenomena of snap judgments.
