Practice Doesn’t Make Perfect, But It Helps

July 3, 2014 7:56 am 2 comments

And now the baPAFF_063014_practiceexpertise_newsfeature-1d news: if you’ve been playing a sport for 20 years and you’re not getting better, you probably never will. Practice can only do so much. How much, exactly, has been calculated by psychologists at Princeton University, who scoured the scientific literature for studies examining practice and performance in domains as diverse as music, games, sports, professions, and education. The Association for Psychological Science reports that, based on a meta-analysis of 88 studies that attempted to equate practice with expertise, the researchers found that overall, practice accounts for only about 12 percent of individual differences observed in performance across the various domains. What does make a difference? The researchers suggest that the age at which a person begins a particular activity matters, and oh yeah, “certain cognitive abilities” also play a role. Here’s the interesting part: the psychologists found that practice accounted for about 26 percent of individual differences in performance for games, about 21 percent of individual differences in music, and about 18 percent of individual differences in sports. But it only accounted for about 4 percent of individual differences in education and less than 1 percent of individual differences in performance in professions– like psychology.

  • So, does that last sentence mean that one does not have to “practice” being a psychologist to be good psychologist? Hmmmm.

  • Most of us geezers don’t pursue a sport or exercise regimen with the usually unattainable hope of being “perfect”. It’s usually for fun and fitness.

    If you’ve tried to be perfect at something for 20 or so years, maybe you ought to try something else or go see a “psychologist”. Hopefully you see one that has a real “practice” and doesn’t waste his/her time on questionable studies.

    Computer Brain Games Are For Losers

    Brain games, the computer based mental challenges that promise to boost the brain power of older adults, are an excellent way to waste time, but they do almost nothing to make us smarter. That’s the opinion of 69 scholars, including many cognitive psychologists and neuroscientists from around the world. A Stanford University news release reports that the scholars, who have jointly issued a statement expressing their skepticism, say that while people who play computer brain games may improve their scores on […]

    Exercise Pain Predicts Broader Pain Threshold

    How much you hurt after exercise is a good predictor of how much you hurt in life, according to research conducted at the Rutgers School of Dental Medicine, where they know a thing or two about pain. Researchers have known for years that exercise generally helps us tolerate pain. They even have a name for the phenomenon; it’s called “exercise-induced hypoanalgesia” or (EIH), but you knew that. Researchers have also known that some people respond better to the pain-diminishing influence of […]

    Worried About Ebola Yet?

    Are you worried about Ebola yet? At least one out of four American are, according to a new Harris Poll/HealthDay survey. And the most disturbing thing about the poll is that it was taken more than a week ago, before a nurse in Dallas who had treated an Ebola patient became sick, compelling the CDC to rethink the preparedness of U.S. medical workers to deal with the crisis. HealthDay reports that the online poll of more than 2,000 adults, taken between Oct. […]

    Repeat Knee Injuries: What Are The Odds?

    Ever wonder what the odds are that you’ll re-injure a knee after an ACL repair? Now we know, and the answer is: it depends how old you are.  If you’re in high school, and if you are reading this you are probably not in high school, you’ve got a 17 percent chance of re-injury. That sounds scary until you read the full report from researchers at the University of North Carolina, which claims a 20 percent chance of injury on […]

    Lifting Weights Improves Your Memory

    Can’t remember how many reps you should do of squat thrusts? Do a few more reps and it might come back to you. Slowly. Researchers at Georgia Tech are persuaded that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent. A Georgia Tech news release admits that the school isn’t the first to find that exercise can improve memory, but their study, which was […]

    Knee Pain? Forget About Acupuncture

    Got a knee that won’t stop giving you pain? Don’t waste your time with acupuncture. According to researchers at the University of Melbourne in Australia, the therapy does little for knee pain in the short term and it does nothing in the long term. Science Daily reports that the researchers treated 300 adults with chronic knee pain either with needle acupuncture, laser acupuncture (hitting acupuncture spots with a low-intensity laser beam), sham laser acupuncture, or no treatment at all (the […]

    Karate Masters Have Faster Brains

    Researchers have known for a while that the power of a karate blow is not all about strength. Rather, it’s about fine coordination between wrists and shoulders. Now researchers at University College in London have learned where that better coordination comes from: a better brain. A University College news release reports that researchers looked for differences in brain structure between 12 karate practitioners with a black belt rank and an average of 13.8 years’ karate experience, and 12 control subjects […]

    Exercise Is Bad For Your Teeth, Maybe

    OK, this is surprising. As Gretchen Reynolds points out in the New York Times, exercise may be good for every part of your body but one: your teeth. Reynolds reports that the good health/bad teeth dichotomy came to the attention of many last year when a study was published in The British Journal of Sports Medicine, in which dentists who examined 278 athletes at the 2012 Summer Olympics in London reported that a majority displayed “poor oral health,” including high levels […]
