Spatial Ability a Predictor of Creativity In Science 199

HonorPoncaCityDotCom writes "The gift for spatial reasoning — the kind that may inspire an imaginative child to dismantle a clock or the family refrigerator — is sometimes referred to as the 'orphan ability' for its tendency to go undetected. Now Douglas Quenqua reports that according to a study published in the journal Psychological Science, spatial ability may be a greater predictor of future creativity or innovation than math or verbal skills, particularly in math, science and related fields. 'Evidence has been mounting over several decades that spatial ability gives us something that we don't capture with traditional measures (PDF) used in educational selection,' says David Lubinski, the lead author of the study and a psychologist at Vanderbilt. 'We could be losing some modern-day Edisons and Fords.' Spatial ability can be best defined as the ability to 'generate, retain, retrieve, and transform well-structured visual images.' Some examples of great inventors who have used their high levels of spatial ability to innovate include James Watt, who is known for improving the steam engine, and James Watson, co-discoverer of the structure of DNA. Nikola Tesla, who provided the basis for alternating current (AC) power systems, is said (or fabled) to have been able to visualize an entire working engine in his mind and be able to test each part over time to see what would break first. Testing spatial aptitude is not particularly difficult but is simply not part of standardized testing because it is considered a cognitive function — the realm of I.Q. and intelligence tests — and is not typically a skill taught in school. 'It's not like math or English, it's not part of an academic curriculum,' says Dr. David Geary. 'It's more of a basic competence. For that reason it just wasn't on people's minds when developing these tests.'"

      You can easily measure them. Getting people to agree on what the measurements mean in practical terms is where we fail.

        I'll expand on this.

        What can you do with two sticks and a string?

        Someone who is creative can take the sticks and string and make a variety of things or use them in a variety of ways.

        Someone with spacial abilities doesn't need to actualize those things or uses, they can visualize them in memory and then describe them (assuming they have language to do so - which is typically where formal education enhances existing abilities).

        Try it yourself. First get the supplies though. You may find that you are creative with them in your hands but may struggle to come up with ideas in memory. Children are especially better at handson creativity and struggle with spacial abilities.

        Some ideas.
        Tools, toys, art, machines, instruments. Don't forget that sticks bend and can be broken. Also you could make a component of something more complex.

            Hold on there cowboy...I got this far into your response...

            Schools are targeted for the middle of the bell curve

            Yeah see, the Bell Curve is not accepted in modern science [wikipedia.org], especially by people like Chomsky.

            Even those who would disagree with Chomsky...drop whatever school or scientist you want, the idea is defunct.

            It's important to also understand *why* because it's a good introduction to high level statistical analysis and how it can be weilded incorrectly.

            A good analogy is to the work of Freud. Practically everyone knows Freud in some way as a famous Psychologist...anyone who has *studied* Psychology at virtually any level can tell you his basic theories, and they'll tell you, as I'm sure you know, that most of his theories have been debunked and now sit in the history's museum of archaic science.

            Archaic but foundational to be sure.

            The 'Bell Curve' is a concept not a scientific law or observed phenomenon. It was constructed using the language of statistics, but an idea or concept nonetheless. It became 'popular' because of its presentation and the general emergence of data analysis in daily life due to changes in technology.

            Put your three claims to a similar level of rigor...you'll see easily that they are all logical fallacies:

            A. Creativity cannot be taught.

            B. Talent is in the context of the time. It isn't fair, but it is true.

            C. The educational system never knows how to detect --- let alone help --- talented young people.

            Data and yes even test scores can tell a trained educator a lot. However...and if anything, take away this **one** truth from this post.....even the **best** data (and 'Bell Curve' is based on severely flawed methodology) is only as good as the person who is interpreting and reporting it.

            • "Bell curve" means normal distribution. Unsurprisingly, human intelligence does follow a normal distribution. Are you disputing that intelligence follows a normal distribution or that there is such a thing as a normal distribution?

                The normal distribution is just a mathematically very easy handable distribution, thus about everyone tries to morph and recalculate scales until the data set somehow follows a normal distribution. It does in no way mean that the observed phenomenon follows a normal distribution. IQ for instance seems to have had two local maxima, one slightly below the median and one around 125, but recalculating the scores of the IQ questions levelled those two maxima.

                Or to make it more explicit: IQ is especially scaled and scored to ensure the distribution of the scores is gaussian.

      • how is creativity not measurable?

        For example, do you measure quantity? (Reality television) or Quality? (Blade Runner) Finding a widely a accepted benchmark might prove to be a challenge...

      • Art has nothing to do with creativity. Design has nothing to do with it either.

        Writers are creative. Musicians are creative. Engineers are creative. Even politicians are creative. Creativity is the act and process of making something new. It is composed of existing parts and pieces whether those are paint, words, ideas or bits but the arrangement is new and unique (until it is copied - which is not a creative act, unless the process of copying is itself new).

        • Except not all engineers create something "new". Many, if not most, play a support role. And many engineering disciplines involve following some very precise sets of rules and standards, even in the "design" of new products, so opportunity for "coming up" with something unique, or patentable, is actually quite uncommon. Many new and practical concepts in product design often comes from industrial designers with more of a background in art than in science and technology.

      • Everything is testable. The question is are you actually measuring what you think you are. That's why I used the word 'measurable'.

        People have been arguing about whether their test for intelligence actually measures anything useful for decades. Spatial ability is a subset of this so pardon my skepticism.

        And as far as creativity goes, well it's ineffable. The idea you can measure it with a test is absurd. About all you can do is give examples of the results of the application of creativity.

        In my own view of my-self, spatial ability and creativeness are one and the same. I do not come up with creative ways to solve a problem, I visually see the problem in my head and the answer just stares me in the face. Some people say that I am creative, while I just feel like I am just putting together a puzzle and I just see all of the pieces and know where to place them.

    The parents were away, and the thing stopped working. This was an older units with a separate compressor and motor - a big belted wheel that turned a pulley on the side of the compressor.

    I took off the front panel. pulled out the frame containing the motor and compressor, and discovered the relay wasn't working. I unplugged it, cleaned/sandpapered the contacts, and put it all back before the parents got home (and told them what happened).

    I also did the clock thing. I modified a mantel clock to a) not ring the hour, and b) start ringing at 2:00 AM and not stop. I hid it under my sister's bed on her wedding night.

Everyone who is identified as an expert in their field (Mozart, Tiger Woods, Jerry Rice &c) had put in enormous amounts of practice before becoming expert. For instance, Mozart was composing at age 4, but didn't write anything particularly good until his twenties (IIRC - may have gotten the ages wrong).

    Feynman, for example, believed that geniuses are common, but due to lack of education, lack of encouragement, poor education, or lack of leisure time they have no chance to blossom. (Meaning: genius-level people are too busy with a job and family to really sit down and create things.)

    The literature and current studies indicate that, barring physical deformity, anyone can become an expert in just about anything. They only have to practice long enough and hard enough.

      There's a higher level of visualization than this. I used to develop high-end animation software, so I met pro 3D animators. I've seen one draw a head by drawing a series of 2D cross sections freehand, then skinning it. I can use the 3D animation program, but I can't do that.

      Sculptors have that skill, too. There's a classic line: "The story is told that the Pope visited Michelangelo in his studio one day, and on seeing him sculpting his statue of David, the Pope asked, "How do you know what to cut away?" The great artist's response was, "I simply chip away anything that doesn't look like David."'

      That is not a joke. There are people whose 3D visualization is that good.

      This may be inherited. I know a good artist whose drawings have hung in the Smithsonian. She has that kind of visualization ability. So do her son and daughter, although neither works as an artist.

(And thank god for that, because if I'd had to stick with the "visual math" curriculum my school'd been pushing, I'd still probably being trying to complete per-algebra...or at least their bizarre, my

    ah yes. Choices choices. Do I want my kid to grow up to be a patent troll? or a slave driver?
    Its so nice to read that David Lubinski, psychologist no less, knows a thing or two about engineering and innovation when he studies them.

  • I have seen hundreds of people who have good spatial skills & always suspected that is what led to the interest in STEM.

    The reason I say this is that young kids with spatial skills develop those before they even hear the acronym STEM before eve kindergarten. They play with tools and disassemble and reassemble all sorts of things...just like I did as far back as I could remember to around 3-4 years of age.

    Some of these people I knew went to college, technical schools and others became skilled builders,

  • ... if you get away from the games long enough to create something. Cool.

  • Memory and spatial ability, and how quickly things a learned in each area. I have a very high degree of spatial ability, and became very good at tech. My guidance councilor insisted that I go to college when all I wanted to do was fix TVs, went one semester and dropped out because I discovered computers and that I didn't need someone to teach it to me. I could fit the pieces of a computer program in my head and spill it out from my fingertips. 35 years later, I'm making over 6 figures without a college ed
  • Testing for intelligence shouldn't be just about what you know and how much you know.. too me, that's more like testing for memory retention. But how do you learn? What do you do with what you know? these can offer much more practical views into a person's intelligence and even dare I say, the level of productivity you could expect. How well do you use what you know?
