Quote:Human beings sometimes falter under pressure. Pilots crash and divers drown. Under the glare of competition, basketball players cannot find the basket and golfers cannot find the pin. When that happens, we say variously that people have “panicked” or, to use the sports colloquialism, “choked.” But what do those words mean? Both are pejoratives. To choke or panic is considered to be as bad as to quit. But are all forms of failure equal?

And what do the forms in which we fail say about who we are and how we think?We live in an age obsessed with success, with documenting the myriad ways by which talented people overcome challenges and obstacles. There is as much to be learned, though, from documenting the myriad ways in which talented people sometimes fail.

“Choking” sounds like a vague and all-encompassing term, yet it describes a very specific kind of failure. For example, psychologists often use a primitive video game to test motor skills. They’ll sit you in front of a computer with a screen that shows four boxes in a row, and a keyboard that has four corresponding buttons in a row. One at a time, x’s start to appear in the boxes on the screen, and you are told that every time this happens you are to push the key corresponding to the box. According to Daniel Willingham, a psychologist at the University of Virginia, if you’re told ahead of time about the pattern in which those x’s will appear, your reaction time in hitting the right key will improve dramatically. You’ll play the game very carefully for a few rounds, until you’ve learned the sequence, and then you’ll get faster and faster. Willingham calls this “explicit learning.” But suppose you’re not told that the x’s appear in a regular sequence, and even after playing the game for a while you’re not aware that there is a pattern. You’ll still get faster: you’ll learn the sequence unconsciously. Willingham calls that “implicit learning”–learning that takes place outside of awareness.

These two learning systems are quite separate, based in different parts of the brain. Willingham says that when you are first taught something–say, how to hit a backhand or an overhead forehand–you think it through in a very deliberate, mechanical manner. But as you get better the implicit system takes over: you start to hit a backhand fluidly, without thinking. The basal ganglia, where implicit learning partially resides, are concerned with force and timing, and when that system kicks in you begin to develop touch and accuracy, the ability to hit a drop shot or place a serve at a hundred miles per hour. “This is something that is going to happen gradually,” Willingham says. “You hit several thousand forehands, after a while you may still be attending to it. But not very much. In the end, you don’t really notice what your hand is doing at all.”

Under conditions of stress, however, the explicit system sometimes takes over. That’s what it means to choke. When Jana Novotna faltered at Wimbledon, it was because she began thinking about her shots again. She lost her fluidity, her touch. She double-faulted on her serves and mis-hit her overheads, the shots that demand the greatest sensitivity in force and timing. She seemed like a different person–playing with the slow, cautious deliberation of a beginner–because, in a sense, she was a beginner again: she was relying on a learning system that she hadn’t used to hit serves and overhead forehands and volleys since she was first taught tennis, as a child. The same thing has happened to Chuck Knoblauch, the New York Yankees’ second baseman, who inexplicably has had trouble throwing the ball to first base. Under the stress of playing in front of forty thousand fans at Yankee Stadium, Knoblauch finds himself reverting to explicit mode, throwing like a Little Leaguer again.

Panic is something else altogether. Consider the following account of a scuba-diving accident, recounted to me by Ephimia Morphew, a human-factors specialist at nasa: “It was an open-water certification dive, Monterey Bay, California, about ten years ago. I was nineteen. I’d been diving for two weeks. This was my first time in the open ocean without the instructor. Just my buddy and I. We had to go about forty feet down, to the bottom of the ocean, and do an exercise where we took our regulators out of our mouth, picked up a spare one that we had on our vest, and practiced breathing out of the spare. My buddy did hers. Then it was my turn. I removed my regulator. I lifted up my secondary regulator. I put it in my mouth, exhaled, to clear the lines, and then I inhaled, and, to my surprise, it was water. I inhaled water. Then the hose that connected that mouthpiece to my tank, my air source, came unlatched and air from the hose came exploding into my face.

“Right away, my hand reached out for my partner’s air supply, as if I was going to rip it out. It was without thought. It was a physiological response. My eyes are seeing my hand do something irresponsible. I’m fighting with myself. Don’t do it. Then I searched my mind for what I could do. And nothing came to mind. All I could remember was one thing: If you can’t take care of yourself, let your buddy take care of you. I let my hand fall back to my side, and I just stood there.”

This is a textbook example of panic. In that moment, Morphew stopped thinking. She forgot that she had another source of air, one that worked perfectly well and that, moments before, she had taken out of her mouth. She forgot that her partner had a working air supply as well, which could easily be shared, and she forgot that grabbing her partner’s regulator would imperil both of them. All she had was her most basic instinct: get air. Stress wipes out short-term memory. People with lots of experience tend not to panic, because when the stress suppresses their short- term memory they still have some residue of experience to draw on. But what did a novice like Morphew have? I searched my mind for what I could do. And nothing came to mind.

Panic, in this sense, is the opposite of choking. Choking is about thinking too much. Panic is about thinking too little. Choking is about loss of instinct. Panic is reversion to instinct. They may look the same, but they are worlds apart.
