Each person’s yes or no answers were used to calculate their loss aversion. At the end of 300 rounds, one round would randomly be chosen and used to calculate the participant’s take-home amount, so it was in the participants’ interest to do their best on each trial. Before each round of the two-second game, they were told what the stakes were for that round - anything from losing $100 to gaining $100. On the second day, the participants were given $100 in cash and then placed in an MRI machine to play the game. ![]() The difficulty of the game was then modified according to the ability of the player so that the task was equally difficult for each participant. On the first day, they learned a brief but challenging video game that required precise hand control. Twenty-six participants, 20 to 30 years old, came in for testing on two consecutive days. By monitoring the participants’ brain activity as they were presented with incentives and then performed a skilled movement task, the researchers found that performance is influenced by a brain area called the ventral striatum. Those with high loss aversion choked when told they stood to gain a lot, while those with low loss aversion choked under the pressure of large prospective losses. ![]() The results of the study, published online in The Journal of Neuroscience on Nov. “We can measure someone’s loss aversion and then frame the task in a way that might help them avoid choking under pressure,” says Vikram Chib, Ph.D., assistant professor of biomedical engineering at the Johns Hopkins University School of Medicine. Recent research from The Johns Hopkins University suggests that in situations like this, performance depends on two factors: the framing of the incentive in terms of a loss or a gain, and a person’s aversion to loss. He regularly makes baskets from much farther away while avoiding defenders, but now, when all is calm, he chokes and misses the basket, and his team loses. It’s a tight game, and his team needs this point. The brain’s ventral striatum seems to be responsible for the choking effect through its mediation of incentives and movement control.Įveryone knows the scene: a basketball player at the free throw line, bouncing the ball as he concentrates on the basket. Those people with high loss aversion choked when faced with high prospective gains, while those with low loss aversion choked when faced with high prospective losses. Researchers measured people’s fear of financial loss and correlated this to how well they performed a difficult, skilled task based on the stakes of their success or failure.
