Researchers Determine What Makes People 'Choke'

We've seen it happen to the best of them.

A world-class athlete is going for the gold when a well-honed skill suddenly deserts him. A concert pianist, finally getting that chance to play in Carnegie Hall, finds her fingers have turned to thumbs. Tiger misses a six-inch putt.

The big moment comes, and goes, and they've blown it.

In a word, they've choked. Even those of us who have never reached the top know the feeling. We should have been able to do something that was easily within our reach, and we couldn't pull it off. Why did our skills fail us when we needed them the most?

Researchers at Michigan State University think they have figured out why. A series of experiments there indicate that we choke because we are trying too hard, not because we aren't trying hard enough.

Science by Golf

"Paying too much attention to the performance breaks down the skill," says Sian L. Beilock, who headed up the research project as part of her doctoral dissertation in psychology. "And that's what causes choking."

Beilock reported her findings in the December issue of the Journal of Experimental Psychology: General, published by the American Psychological Association. Beilock and her faculty adviser, Thomas H. Carr, brought 54 male and female students into their lab and taught them how to play golf. Or at least how to putt.

Tests were designed to see if the researchers could induce choking, which they found they could do fairly easily, and whether people could be "vaccinated" against choking by exposing them to such things as distractions. If they could, the researchers reasoned, they could figure out what provides the best "inoculation," and that would tell them what causes choking.

"There are two theories on why people choke under pressure," Beilock says. "One theory suggests that under pressure, you become distracted by the pressure, or the audience, or the consequences of failure. In essence, you don't pay enough attention to your skill.

"Another theory predicts just the opposite. You get in a high-pressure situation and you start paying too much attention to your skill. You start trying to control it in a way that you never did in practice.

"They both seem plausible."

The researchers divided the participants into three groups and brought in experts to teach them how to putt. One group tried to master that maddening skill without any distractions. But a second group was faced with a daunting distraction. They learned putting while listening to words on a tape recorder and repeating a target word every time they heard it.

The third group putted with a video camera set up in front of them, and they were told to pay close attention to their performance because golf pros would be reviewing the tapes. The idea there was to make the members of the third group very self-conscious as they tried to learn to putt.

Practice Under Pressure

Beilock says all three groups developed their putting skill to a high level. Then they were put through two tests, one low pressure and one high, to see how they performed. All three groups performed well under low-pressure conditions.

But that changed dramatically when the pressure rose. The participants were told they would receive a monetary reward (a measly $5, but enough to get their interest) if they could improve their performance in the second test. They were also told that they had been paired with another participant, and both would have to improve to receive the reward.
