Missed Kicks Make Brain See Smaller Goal Post

fieldgoal

Flubbing a field goal kick doesn’t just bruise your ego — new research shows it may actually change how your brain sees the goal posts.

In a study of 23 non-football athletes who each kicked 10 field goals, researchers found that players’ performance directly affected their perception of the size of the goal: After a series of missed kicks, athletes perceived the post to be taller and more narrow than before, while successful kicks made the post appear larger-than-life.

Professional athletes have long claimed that their perception changes when they’re playing well — they start hitting baseballs as large as grapefruits, or aiming at golf holes the size of a bucket — but many scientists have been slow to accept that performance can alter visual perception.

“The reason why this is so radical is that perception has always been conceived as being all about information received by the eye,” said pychology researcher Jessica Witt of Purdue University, who co-authored the paper published last month in Perception. “In my studies we keep all the optical information constant, so the eye is seeing the exact same info — but it looks different depending on performance.”

According to visual perception researcher Maggie Shiffrar of Rutgers University, who was not involved in the research, Witt’s conclusions are troubling to many scientists because they suggest that computer studies of perception might not be a reflection of reality.

“If Witt is right that what we see depends upon what we can do, then it logically follows that many of us have spent our lives studying perception in the WRONG WAY,” Shiffrar wrote in an e-mail. “In the vast majority of studies conducted in my lab, for example, observers view displays on a flat computer screen and make simple, dichotomous judgments about their perceptions of those displays. Thus, subjects in my studies don’t do anything other than push a button. The results of Witt’s studies suggest that the results that I’ve collected and the corresponding theoretical conclusions that I’ve drawn won’t generalize to perception in the real world. In the real world, people look at objects so that they can do something with those objects.”

Although many scientists are surprised, Witt says subjective perception is a concept most of us are already familiar with. For example, she said, when running around a track, you may know logically that long, straight stretch is always a constant 100 meters — but by the end of a run, those same 100 meters appear to stretch on forever.

Witt and her colleague, graduate student and former football player Travis Dorsch, chose to experiment with field goal kicks because they wanted to study the disconnect between what people think they can do and what they can actually accomplish. “When you watch college and pro football, field goal kicks seem so easy,” Witt said. “But when I went out with Travis to try it myself, it was actually really hard to do.”

goal-fig-1The researchers used a small, adjustable replica of a goal post to test players’ perception before and after attempting 10 kicks. While standing in front of the real-life goal, participants were asked to adjust the width and height of the model to scale.

The players’ pre-performance estimations didn’t correlate at all with their subsequent success rate. But after 10 field goal attempts, their perceived goal size was highly correlated with peformance.

Interestingly, the change in players’ perception didn’t just depend on how many goals they missed — it also mattered how they missed their goals. Folks who failed because they didn’t kick high enough perceived the crossbar to be taller, while those who kicked to the side viewed it as more narrow.

Previous studies by Witt and her colleagues have shown that performance can also influence perception among golfers and softball players. But the researchers say this is the first time that particular performance errors have been correlated with specific effects on perception.

“One of the things that has been asked of us in our research is, if you’re playing well, do you just see everything as bigger, does the whole world look like it’s expanded?” Witt said. “But this research shows that changes in perception are specific to what you’re acting on.”

Next, Witt hopes to look at whether professional athletes can improve their performance by changing their pre-game perceptions. For instance, are golfers who see a larger hole more likely to make the shot? “Currently, we’re testing this using visual illusions in golf that make the hole look bigger or smaller,” Witt said.

Why Eggs Could Be Getting Harder to Peel

eggs

Consider the farm-fresh egg, the pristine symbol of the simple days of pre-industrial farming.

People love them, but there’s a problem: They seem to be getting harder to peel. And though I’ve messily discovered this on my own, there’s some science to back this idea up.

Here in food-crazed San Francisco, fresh eggs are everywhere. After purchasing some of these just-collected treasures for hard boiling, I found it nearly impossible to peel off their shells without pockmarking them. My once-beautiful eggs ended up with more craters than the moon.

It couldn’t be my fault, I told myself. I’d been hard-boiling eggs for decades, most intensively during a six-month egg-salad kick in ninth grade. I got my technique down and everything.

What happened, then?

As an egg ages, it loses some carbon dioxide through tiny pores in the shell, making the egg white more basic. At the same time, it loses moisture, which increases the size of the “air cell” at the bottom of the shell, between the inner and outer membranes. The dynamics of this process are, in the words of a University of California, Davis agriculture publication, “not completely understood,” but the combination of these changes makes an old egg a lot easier to peel than a one that is fresh out of the bird.

“The best guarantee of easy peeling is to use old eggs!” wrote Harold McGee, in his monster 800-page tome, On Food and Cooking: The Science and Lore of the Kitchen. “Difficult peeling is characteristic of fresh eggs with a relatively low albumen pH, which somehow causes the albumen to adhere to the inner shell membrane more strongly than it coheres to itself.”egg-schematic

The USDA provides a complementary explanation more focused on the air cell, which you can see in the schematic, sitting between the outer and inner shell membranes.

“As the contents of the egg contracts and the air cell enlarges, the shell becomes easier to peel,” the USDA Shell Eggs from Farm to Table fact sheet states. “For this reason, older eggs make better candidates for hard cooking,”

McGee also suggests an easy cooking chemistry solution.

“If you end up with a carton of very fresh eggs and need to cook them right away, you can add a half teaspoon of baking soda to a quart of water to make the cooking water alkaline (though this intensifies the sulfury flavor),” he wrote.

While I’ve noticed the Peeling Problem most distinctly with superfresh farm eggs, the eggs you buy at the supermarket could be getting fresher too. Most American eggs are produced and distributed by agribusiness concerns like Cal-Maine and Rose Acre, which each have more than 20 million hens cranking out eggs just for you.

Statistics on the time it takes for an egg to go from hen to supermarket have not been calculated, a USDA representative told Wired.com, but there’s some reason to believe that new production techniques could be delivering eggs to markets faster.

A 1998 report by the agency found that big consolidated chicken egg facilities, which wash and package the eggs on-site instead of sending them to a separate processing location, could reduce the time from farm to store from 100 hours to 53 hours. And, according to Cal-Maine’s SEC filings, the industry continues to centralize, squeezing out the old facilities in favor of the new ones.

Eggs tend to sit on the retail shelf longer than they spend in processing and distribution, so the few extra days of freshness might not make the eggs as dramatically hard to peel as farm eggs.

But if you have any trouble, consider another technofix: automatic Eggstractor egg peeler, anyone?
