![]() The explosion had happened unexpectedly, firing the metal bar up through his prefrontal cortex, leaving a hole clear through. This was usually used to help plant explosives, clearing the way for a future railroad, but now lay covered in blood and gore. The patient in question – Phineas Gage – had just been struck through his head by a narrow iron pole. This was – mercifully – not an ordinary case. Williams was politely informed that there was someone in need of his assistance, and soon found the patient vomiting out part of his own brain. On a summer’s day in Vermont, in 1848, a young Dr. When we steer clear of risky situations, or exert control over ourselves in some way, we are using our executive function to keep ourselves in line.ĭamage to the prefrontal cortex often leads to a worsening of this executive function, and individuals can become pleasure-seeking and hedonistic – less able to plan for the future, more keen to live in the present. Our ability to think clearly is maintained through executive function – not a soirée for business professionals, but a set of cognitive processes that control how we act in day-to-day life. The very first study that utilized the test recruited individuals with prefrontal cortex damage as participants, finding that they too were susceptible to losses in the long run.Īs the original study demonstrated, one of the frequent outcomes from prefrontal cortex damage is the worsening of decision-making capabilities. It’s not only problem gamblers who struggle to see clearly when presented with this task however. Luck of the Drawįor some people however – problem gamblers in particular – the thrill of the bigger win is too much of a pull, and they will continue to select the “bad” decks even as the losses pile up. They consistently select the decks that deliver profit over the long-term. The decks never change in their likelihoods of delivering a profit or loss, so eventually the average person figures this out, and sticks to a strategy. While the participants complete the test, they have some information available to them – how their earnings (or losses) are looking. Of course, this information isn’t revealed to the participant – just that they should win as much money as possible. The other two decks however provide huge profits, but also huge losses, and over enough trials will leave you bankrupt. They don’t give big wins, but the losses (or “punishments”) are smaller, and you’ll come out on top if you stick to them. Two of the decks that can be selected will reliably provide a profit in the long-term. Unlike casinos however, the cards really are stacked in your favor – or against them. This decision-making required that the participants simply select a card from one of four decks – hardly a tricky bet. And one of the ways this can be tested is with the Iowa Gambling Task.įirst designed by Antoine Bechara and others in 1994, the test was originally used to measure decision-making abilities. One of the hallmarks (maybe the hallmark) of an unhealthy gambling approach is the failure to objectively evaluate the odds they are faced with. Now classified as an addiction, problem gambling has been recognized by the DSM-V as a disorder akin to substance abuse. The trope of a gambler pushing their luck too far is something we’re all familiar with. He joins a long list of gamblers who have defied the odds, but only for a while. With only $50 in his pocket, and a gambling spree in Las Vegas, he made himself a multimillionaire in a matter of weeks. The story of Archie Karas is true, but it reads like a legend.
