In gambling, brain explains attraction of near-misses

By Elizabeth Landau
CNN.com Health Writer/Producer

You pull the lever on the slot machine and get two cherries and a lemon. Or you throw down dice and get a six, then an eight, when you were aiming for a seven. So close! Play again!

We get a rush from playing games that we feel like we've almost won, but have lost by a small margin. For people who gamble, the allure of the "near miss" can keep the dice rolling, the slots turning, and the money slipping away.

A new study in the Journal of Neuroscience looks deeper into the mind of the gambler. Psychology researchers Henry Chase and Luke Clark looked at 20 regular gamblers. Participants varied from recreational gamblers to "pathological gamblers," meaning their habits may interfere with everyday life.

Researchers scanned the brains of these gamblers while they performed a simplified slot machine task. Although the sample size is small, studies that make use of functional magnetic resonance imaging (fMRI) tend to have fewer participants than survey-based experiments, and can still have important implications.

The study found that near-miss outcomes during gambling involve the brain's reward system; in particular, areas called the ventral striatum and the anterior insula.

A previous study on healthy volunteers also found that near misses are linked with heightened activity in these same brain regions associated with monetary wins.

Scientists have long known that a small cluster of brain cells that release a chemical called dopamine have been associated with addiction, but there has never been a clear explanation for it.

"This study provides an important advance in our understanding of how the brain's reward circuits underlie one form of addictive behavior, pathological gambling," said Steven Quartz, director of the California Institute of Technology’s Brain, Mind, and Society Ph.D. program, who was not involved in the study. "Many modern games of chance, especially slot machines, compel some people to play repeatedly even when they are not winning," he said in an e-mail.

Chase and Clark also showed that the more severe a person's gambling is, the more these near misses trigger the reward circuit. But the brain region in question is also involved in learning. That means the gambler's brain may be "tricked" into thinking that it is learning new information about the environment through near misses, Quartz said.

"Ultimately, a better understanding of the rewarding effects of near misses may have implications for both treating problem gambling and for regulatory practices of the gambling industry," he said.

The authors noted that they did not take into account such conditions as nicotine dependence and personality disorders, which may have impacted the brains and behaviors of participants. Also,the group of regular gamblers in this study was almost all male.

Further research is necessary to determine more conclusively how the minds of gamblers work.

    Our company is given many models of failure, in contrast.
    There are times each and every breakup occurs because the man's friends get operating.

    Based on research, there are now millions
    of marketers worldwide whoo arre applying article marketibg in promkoting
    their products together wwith their website online.

    It has rssulted to regarding articles that are now posted on various publishing site which much difficult
    anybody to capture the eye of their buyers.

    Websites that don't include a blog. If used correctly, blogs get
    round the internet through feeds. This idea is really perplexing to many people but has
    beesn proven end up being beneficial.

    Link the directories which human-edited , nor accept spam oor adult content.

    Reciprocal links aare less effective than hyperlinks so
    is actually possible to better to a links page.

    Become a part! There are wide ranging affiiate programs you can join that deal with mulltiple companies just chomping at the bitt to have
    somebody like you promote many. In my opinion affiliate programs are simplest way to get a beginner or expert in order to money having a blog.
    Cj . com aand Click Bank the actual most favorable.
    Did you know yyou might make up to 75% commissoon oon propducts
    you sell on yur site site with commission junction?

    Good content aand condistent link building – the two mst impprtant factors of
    Used .. Gone are the days where any links were good enouigh to achieve good page ranks with the major searcch engines.
    Now you should take utmost care oon who are linking for and from which?
    You must came actoss the terms like "relevant web site/page" and "good neighborhood".
    It helps to eensure that you find more credit if you gett back-linking from internet which are depedent on tthe same theme as
    yours and preferably have high pawge ranks – tougher the bigger.
    And instead of placing your url as links use your main keywords
    as Anchor Textt links.

    Without an effective page, will probably find it hard to maie quick money online.
    The landing page iis access making you money. Don't give
    poor effort in completing this task. It is major reeason for the downfall
    many Internet marketing campaigns.

    Don't class the hype of a shot solution, can be no guaranteed overnight in order to your site visitors.

    You must build the interest in your website slowly bbut strongly
    occasion. It may take weeks to months and
    perchance even years or more. But if you complete the work right you will be rewarded
    with a company reeputation and customer basde that get spread anywhere in thee web for the future.
