other examples of visual processing

Okay, previous attempt did not work. I may have to check a few settings in Google docs. Anyway, here's what I was trying to post.

Modern Artist Spotlight - Dave Devries

I haven't been feeling well this past week. I'm afraid my allergies triggered an episode of moderate dehydration and I spent my time off from work rehydrating. I do have a few science posts planned, as well as breaking my art survey into two smaller surveys. In the meanwhile, I will share an artist brought to my attention by a friend.

Dave Devries uses his skill to bring children's drawings into the realm of super-hero graphic style. He uses real images drawn by children, and with an opaque projector, uses acrylic, airbrush, and colored pencil to make them look realistic. This work became the Monster Engine book. Devries brings his work to the public, letting children participate and teaching college students how to do what he does in workshops and lectures. I love it when adults reach out to children and transgenerational communication occurs in a way that validates the imagination.

Subliminal stimuli processing

About a month ago, a friend of mine in the psychology profession, who is a fan of Derren Brown, had me watch this video:



It is an interesting experiment and a very well done one. I like the fact that they included two subjects who were internal controls. I think that it would be a very good idea to repeat the experiment for a larger population, with controls who hadn't even laid eyes on the CD they sent out. Another example of subliminal priming is Derren Brown influences two gentlemen who work in the US advertising industry. Even advertising professionals can be influenced. This video includes the explanation of how he did it. You might want to check out the UK version too.


Another interesting study is the Duke University Subliminal Ad Experiment:



Research=> Automatic Effects of Brand Exposure on Motivated Behavior: How Apple Makes You “Think Different”

This article first examines whether brand exposure elicits automatic behavioral effects as does exposure to social primes. Results support the translation of these effects: participants primed with Apple logos behave more creatively than IBM primed and controls; Disney-primed participants behave more honestly than E!-primed participants and controls. Second, this article investigates the hypothesis that exposure to goal-relevant brands (i.e., those that represent a positively valenced characteristic) elicits behavior that is goal directed in nature. Three experiments demonstrate that the primed behavior showed typical goal-directed qualities, including increased performance postdelay, decreased performance postprogress, and moderation by motivation.


What does this mean, besides the fact that humans can be easily manipulated? These experiments, tricks, and studies show that our minds process information on an unconscious level. In fact, it could be argued that some intuitive may come from this subliminal data processing. (Some intuition comes from the capacity to process things in a global manner.) This ability probably wasn't developed as a means to be influenced, though it probably helps with social interaction, but there is some evidence that it can improve our safety. The Gift of Fear written by security expert Gavin de Becker, suggests that the hunches and gut feelings we sometimes get come from picking up on certain cues that our conscious minds miss. It is a very easy and fascinating book to read, despite it's length. I highly recommend The Gift of Fear to anyone interested in personal safety or even just human behavior.

The way I see it, our minds have to regulate some of the processing of stimuli to the subliminal level because if it was all conscious, we'd get overwhelmed. And while this process can have some undesirable results, it does serve some very important functions.

Modern Artist Spotlight - Julian Beever

Words really can't do Julian Beever's sidewalk art justice. I've seen him compared to Picasso, which is very misleading. Whereas Picasso went for flat abstractions, Beever goes for hyper-realism by making trompe l'oeil art that creates the illusion of three dimensions. Though I will give you that the works of both artists will challenge your preceptions.



Above is a video of him creating a sidewalk/pavement illusion for Aveeno. In addition to his official website, there is also a Flicker gallery of his works.

Tipping Points

A couple of weeks ago, a commenter directed me to Change Therapy, a free online book about marketing "soft skills" like therapy by David P. Diana. I'm a little leary of promoting things from sources I'm not sure of, so my first action after seeing the comment was to email the link to a friend of mine who has been a practicing psychologist for over 40 years. His response was not only positive, but there was the hint that it would do me some good too.

I did enjoy reading the book. Among the gems within it, was a revisitation of Malcolm Gladwell's 10,000 hours rule. In a nutshell, 10,000 hours of practice is the tipping point of making one an expert at a skill. Diana extended the rule into an exercise program for one's career.

Yesterday, I visited Positivityratio.com, Dr. Barbara Fredrickson's site. Fredrickson found through her studies that "that experiencing positive emotions in a 3-to-1 ratio with negative ones leads people to a tipping point beyond which they naturally become more resilient to adversity and effortlessly achieve what they once could only imagine." Knowing that negativity is one of my worse inner demons, I've decided to track my positive/negative ratio on her site.

Most of my life, I've been told that it takes 21 days to create a new habit. I've have started several "habits" this way, only to have them get squashed by major life upheavals months later. The thing is I don't want new habits, I want an effective lifestyle where I take better care of myself than I do now. I can't do this by being a "habitist". That's how I developed my toolbox of immediate stress relievers. What I need to do is to become an expert - a master - of personally dealing with stress and depression.

So, how can I apply the 10,000 hour rule here? Well, to make it more manageable, I've decided that I would focus on two things - becoming an "expert" at realistic positiveness and becoming an expert at visual processing. The first is for my health; the second is for a career. If I were to assume that I could apply myself to one of these goals 16 hours a day, then it would take me 625 days or about 22 months to gain expertise. Though that is hardly a realistic expectation, especially since I have health concerns that bring the Spoon Theory into play. If I did an hour a day, it would take me a little over 357 months or close to 30 years to achieve the 10,000 hours by rough estimate. After a few more calculations and based on the fact that I tend to have 5 year cycles in my life, I've decided to make a goal of doing at least 2000 hours of effort to my mastery of these two fields, per year. This means about 5.5 hours a day or 38 hours a week. Luckily for me, I can integrate these tasks in with my other activities, and in fact, I already am to some extent. It might take me a little while to get that going strong, but I suspect that once I do, the 5.5 hour practice will naturally extend itself. And on those days when it's harder, I will remind myself that even if I have been doing it for several months, I still have to reach that 10,000 hours.

Using the Web in a right brain way

Pivot is a bit like how the right brain sorts and compares data, looking for patterns, anomalies and relationships. Like the right hemisphere, Pivot relies on global processing and dealing with generalities. I suspect as it becomes more used, Pivot will also specialize in finding patterns that can be described visually, but are difficult to describe in words. And like the right brain, Pivot arranges visual stimuli by appearance, using stored data to arrange parts.

Our right brains take simultaneous streams of information and created a master collage of that moment, using images, sounds, tastes, smells and feelings (both tactile and emotional). It manipulates those streams of information in ways not unlike Pivot's algorithms. What is amazing is that the right hemisphere is better at catching errors than the left. It is easier to prime, benefiting from even the weakest association. It is also easier to update with new information.

The "Dawn of Reason" gave humanity the opportunity to hone many left-brain dependent processes. I foresee this as the "Dawn of Global Analysis", which will hone many right-brain dependent functions in the decades and maybe centuries to come. I look forward to the other data analysis tools that will be spawned by this.

How we learn to see

Pawan Sinha talks about how our brains learn to see, based on his research with blind children and adults in India. Despite what some scientists had extrapolated from animal studies about sight, human brains can learn how to see even after many years of vision deprivation, even into adulthood.

"The one thing that the visual system needs in order to begin parsing the world is dynamic information."

This makes a world of sense when you consider that visual perception is dependent on eye movement. Vision and movement are linked. To quote Wikipedia: "Humans and other animals do not look at a scene in fixed steadiness; instead, the eyes move around, locating interesting parts of the scene and building up a mental 'map' corresponding to the scene. One reason for the saccadic movement of the human eye is that the central part of the retina—known as the fovea—plays a critical role in resolving objects. By moving the eye so that small parts of a scene can be sensed with greater resolution, body resources can be used more efficiently."

Try this. Focus on the red dot in the image below. After a while, the blue circle will start to fade. This illusion is based on how your eyes move.


[If you're like me, you will find it hard to stay focus on the dot once you notice the circle starting to look different. I actually got a headache fighting the impulse to compensate for the lack of microsaccade movement, through the use of gross eye movement.]

Visually thinking and different types of minds

Temple Grandin talks about thinking in pictures. I am so grateful that she has been able to find a way to verbalize how she visually processes things. There is no way I could possibly match her explanations. I straddle verbal and visual processing, but that doesn't mean that I totally understand a visual mind that doesn't has the access to the verbal skills I have. I know that I use visual processing. I also know that there I have not fully developed my visual processing ability. Verbally and mathematically, I had the training. I've been writing poetry since I was seven years old, thanks to my second grade teacher, who introduced poetry writing as part of an English/spelling lesson.

In this world of internet videos, I hope that more people like Temple Gardin are able to show us how to visually think - not only for those like me who intuit its power extends further than we see, but for everyone's benefit.

Visual Processing

I am a very visual person. I was raised by an artist and a computer programmer. This gave me access to artistic and flow-charting techniques. My dad used give my siblings and I flow chart templates to make art when we were young. When I became older, he explained what some of the shapes meant and then made a game for me. He'd give me a simple task and I would diagram the steps to do it, using those shapes properly.

As a family, we made almost weekly trips to the public library, bringing home art and music in addition to a multitude of books. Our home library sometimes had better references than my school's library. Arguments between myself and the sister just younger than me were usually solved by encyclopedias at ten paces. My mother made sure we had art classes. My dad made sure we had science lab kits. As a family, we made candles, leather and other crafts. Dad would also print out wall-size mazes which we kids and my mother would solved together. When I learned how to process information, it was not only through the verbal and mathematical means, but also visual and kinetic means.

I'm right handed, left eyed, and I have no dominant foot preference. I have taken math courses up to and including partial differential equations and I have about the same amount of credit hours in studio art as I do math. It probably follows without saying that my favorite math class was analytical geometry. I feel that this makes me qualified to make the follow statement:

Calculations can be done visually as well as mathematically.

Anecdotal evidence: When I was in high school, my mother took one of my classmates and I to an UIL science competition. Between the tests, the contestant schools could work on brain teasers. One of them was a word problem about how much material a sculptor would need if they made a bust twice as large in every dimension. While my extremely intelligent classmate began to do the mathematical calculations, my mother read the problem and immediately gave the correct answer. After verifying it with math, my shocked classmate asked my mother how she did the calculation. She used pictures and hand gestures to explain her thought process. He was totally lost by her explanation, so I gave him an interpretation he could understand. For the rest of the problems, my classmate and mother answered them with their own methods, while I translated between the two of them. In every case, both methods gave the same answers.

Historical evidence: All those wonderful geometry and trignometry relationships started out as a function of the relationships between visual elements such as lines, points, angles, planes and solids. M. C. Escher discovered several crystallography relationships years before the mathematical models, through purely graphical means. While many mathematicians hold Escher in the highest regard and consider him to have had an exceptional mathematical mind, he actually did very poorly with math in school and struggled to understand the mathematical treatises sent to him when he was older.

So, having made put that pet peeve to rest, I will share with you a diagram I made a few months ago showing visual processing as part of the problem solving process. While I do not detail how to do math visually (perhaps I will do that in another post), the diagram does show some of the ways visual processing has brought about solutions -> http://cosmicsiren.blogspot.com/p/diagram-of-visual-processing.html
