It’s 2:45 p.m. on Labor Day afternoon, with the remnants of Hurricane Harvey whipping across Lake Champlain, turning the sapphire-blue surface into a froth of whitecaps. An exhausted-looking man cleats his Laser to the dock at the Community Sailing Center, clearly beaten by the aggressive breeze. “Anybody want to sail?” he says, ironically.

“Yes!” says Caroline Patten with no trace of irony. As the coach of the UVM Sailing Team, she’s as game for the big gusts as the thirty-four athletes who’ve been prepping by smearing on sunscreen, gobbling up late-lunch sandwiches, zipping up booties, and securing Helly Hansen gear to help keep the water at bay on this seventy-seven degree day.

On Lake Champlain four days a week from 2:45 until 6 p.m., traveling to four to six regattas on weekends and working out with a trainer two mornings a week, this team is as serious about sailing as Alabama is about football. What it lacks in varsity status, it more than makes up for in conviction, camaraderie, and showing how Catamounts can shine on these double-handed dinghies.

“Every single person on the team is highly competitive and wants to win,” says Lindsay Doyle ’19. “Eat, sleep, homework and sail. Not too much time for anything else, but I wouldn’t have it any other way.”

Out on the water, Patten barks orders for a warm-up drill through a megaphone, circling back on her Boston Whaler to herd two boats that have mistakenly crossed in front of The Spirit of Ethan Allen. A yellow bailer’s gone overboard and bobs along the blue. “Some kids think it’s just a lake and don’t realize how hard it blows,” says Patten, a lifelong sailor who began coaching the team in the fall of 2015 and has since seen the Cats qualify for National Championships, placing seventh in 2015 and 2016; this sport, she says, has many surprises. “It requires a tremendous amount of physical endurance as well as mental.”

Team president Brittney Manning laughs when asked about the typical perception of sailing. “The expensive, ‘Let’s wear white linen and drink cocktails on a nice yacht’ kind of thing?” she says. “We find that comical because we know what we are doing is just as intense as any other sport.” The team does its own fundraising, and will soon be moving into Burlington’s new sailing center after years of working out of containers.

It’s not always this windy on the lake, of course. Dead calm can reign, or rain can, or freezing sleet and snow. Two years ago, Manning was part of a crew that ventured out on February 2 to kick off the spring season, bailing ice out of the boats. 

The payoff is not only results, but also a remarkable sense of place for all members of the UVM Sailing Team. “Champlain is one of the absolute best venues in college sailing,” says Patten, explaining how training inside or outside of the breakwater can simulate a wide variety of conditions on lakes and oceans. “For a big portion of our seasons, there are few other boats on the lake, so it feels like our own personal playground. We also get to see some pretty epic sunsets over the Adirondacks.”

When we’re on a diet, we’ll avoid cheeseburgers and ice cream and other foods we love, even though we’re ravenous and hankering for them. Once off the diet, we’ll often return to stuffing ourselves with goodies – even if we aren’t hungry.

We learn self-control while we’re dieting. But a new study by University of Vermont researchers suggests that control of consumption isn’t simply a great act of will power but possibly is guided by the states of hunger and satiety.

During a diet, hunger may become the context in which we learn to deny eating impulses. When we stop dieting and no longer feel hungry, the context vanishes, and we may lose the inclination to restrain our food intake. That’s perhaps a reason why weight regain after a diet ends is so common.

Context matters, explains Mark Bouton, the UVM psychology professor who co-authored the study with his Ph.D student Scott Schepers, scheduled for publication in the journal Psychological Science. For years, he has looked at the importance of context in controlling behavioral and emotional responses.

His research shows that the suppression of behavior or emotion depends upon context – a physical setting, a time period or an internal state such as hunger, mood or the influence of a drug. And the behavior or emotion will “renew” when the context changes or returns to where it was when the response was learned.

For the study, Schepers and Bouton tested rats in two different “contexts” – hungry or satiated. The satiated rats, fed a plentiful amount, could press a little lever to dispense a sweet-fatty pellet, like candy. Even though they weren’t hungry, they chose to press for the treat.

Then, when they were food-deprived for 23 hours a day, the rats didn’t get any pellets when they pressed the lever. Before long, they stopped pressing. They learned to inhibit their food-seeking behavior – but only while they were hungry. When they were satiated again by eating a normal amount of food, they started pressing the lever to get pellets again.

“If you learn to inhibit your behavior when you’re hungry and then are tested in a non-hungry, satiated state, the behavior comes back,” Bouton said. “The real point is hunger and satiety are internal contexts that can control behavior and behavioral inhibition.”

Bouton is collaborating with University of California San Diego researchers who work with obese children. The study teaches the kids to inhibit their craving in the presence of food and food cues, and also studies the role of context.

“You need to practice the inhibition in the context where it’s going to matter,” Bouton says. “You want to learn to control your eating in the presence of all those cues that have been so hard.”

Bouton’s research also could inform treatment of opioid or other drug abuse. He draws parallels between overeating and addiction, alcoholism and smoking – habit-forming behaviors in response to cues, and influenced by context. Drug rehabilitation programs, like diets, create a context for suppressing the behavior, Bouton says, so it’s not surprising that addicts can relapse when they get out of such programs and back to their normal lives.

Bouton, assistant director of UVM’s Neuroscience Graduate Program, specializes in understanding basic learning processes– the development of emotional or behavioral responses in association with certain events or cues. Years ago, he started looking at fear conditioning to understand phobias, anxiety and post-traumatic stress disorder. When rats received an electric shock every time they heard a particular sound, they learned to grow fearful upon hearing that sound. Then, when the sound played over and over without the shock, the fear response subsided, or became “extinguished.”

The clinical psychology practice of exposure therapy works on this concept: By exposing patients again and again to the trigger that makes them scared or anxious, without any harm coming to them, their response gradually subsides. But if the context changes or returns to a previous state, the response can resurface. It’s not erased.

“You can learn things, but as the world changes, we need to be able to change our behavior or change our knowledge,” he said. “We can get rid of the fear, but it comes back really easily.”

Because context is key to controlling behavior, Bouton hopes his work expands the understanding of this concept and sheds light on what causes – and could inhibit – addictive behavior.
