2. Animals could help reveal why humans fall for illusions

By Laura Kelley and Jennifer Kelley


Visual illusions, such as the rabbit-duck (shown below) and café wall are fascinating because they remind us of the discrepancy between perception and reality. But our knowledge of such illusions has been largely limited to studying humans.

That is now changing. There is mounting evidence that other animals can fall prey to the same illusions. Understanding whether these illusions arise in different brains could help us understand how evolution shapes visual perception.

For neuroscientists and psychologists, illusions not only reveal how visual scenes are interpreted and mentally reconstructed, they also highlight constraints in our perception. They can take hundreds of different forms and can affect our perception of size, motion, colour, brightness, 3D form and much more.

Artists, architects and designers have used illusions for centuries to distort our perception. Some of the most common types of illusory percepts are those that affect the impression of size, length, or distance. For example, Ancient Greek architects designed columns for buildings so that they tapered and narrowed towards the top, creating the impression of a taller building when viewed from the ground. This type of illusion is called forced perspective, commonly used in ornamental gardens and stage design to make scenes appear larger or smaller.

As visual processing needs to be both rapid and generally accurate, the brain constantly uses shortcuts and makes assumptions about the world that can, in some cases, be misleading. For example, the brain uses assumptions and the visual information surrounding an object (such as light level and presence of shadows) to adjust the perception of colour accordingly.

Known as colour constancy, this perceptual process can be illustrated by the illusion of the coloured tiles. Both squares with asterisks are of the same colour, but the square on top of the cube in direct light appears brown whereas the square on the side in shadow appears orange, because the brain adjusts colour perception based on light conditions.

These illusions are the result of visual processes shaped by evolution. Using that process may have been once beneficial (or still is), but it also allows our brains to be tricked. If it happens to humans, then it might happen to other animals too. And, if animals are tricked by the same illusions, then perhaps revealing why a different evolutionary path leads to the same visual process might help us understand why evolution favours this development.

Duck-Rabbit_illusion

The idea that animal colouration might appear illusory was raised more than 100 years ago by American artist and naturalist Abbott Thayer and his son Gerald. Thayer was aware of the “optical tricks” used by artists and he argued that animal colouration could similarly create special effects, allowing animals with gaudy colouration to apparently become invisible.

In a recent review of animal illusions (and other sensory forms of manipulation), we found evidence in support of Thayer’s original ideas. Although the evidence is only recently emerging, it seems, like humans, animals can perceive and create a range of visual illusions.

Animals use visual signals (such as their colour patterns) for many purposes, including finding a mate and avoiding being eaten. Illusions can play a role in many of these scenarios.

Great bowerbirds could be the ultimate illusory artists. For example, their males construct forced perspective illusions to make them more attractive to mates. Similar to Greek architects, this illusion may affect the female’s perception of size.

Animals may also change their perceived size by changing their social surroundings. Female fiddler crabs prefer to mate with large-clawed males. When a male has two smaller clawed males on either side of him he is more attractive to a female (because he looks relatively larger) than if he was surrounded by two larger clawed males.

This effect is known as the Ebbinghaus illusion, and suggests that males may easily manipulate their perceived attractiveness by surrounding themselves with less attractive rivals. However, there is not yet any evidence that male fiddler crabs actively move to court near smaller males.

We still know very little about how non-human animals process visual information so the perceptual effects of many illusions remains untested. There is variation among species in terms of how illusions are perceived, highlighting that every species occupies its own unique perceptual world with different sets of rules and constraints. But the 19th Century physiologist Johannes Purkinje was onto something when he said: “Deceptions of the senses are the truths of perception.”

In the past 50 years, scientists have become aware that the sensory abilities of animals can be radically different from our own. Visual illusions (and those in the non-visual senses) are a crucial tool for determining what perceptual assumptions animals make about the world around them.

Laura Kelley is a research fellow at the University of Cambridge and Jennifer Kelley is a Research Associate at the University of Western Australia. They are the co-authors of the paper ‘Animal visual illusion and confusion: the importance of a perceptual perspective‘, published in the journal Behavioural Ecology.

Bringing together significant work on all aspects of the subject, Behavioral Ecology is broad-based and covers both empirical and theoretical approaches. Studies on the whole range of behaving organisms, including plants, invertebrates, vertebrates, and humans, are welcomed.

3. FOODFIC: Please Welcome St. John Karp, Author of Radium Baby

https://www.goodreads.com/book/show/17852853-radium-baby



My favorite ice-breaker on a first date is, "If you could travel back in time to any period, when would you go?" You can tell a lot about a person by how they answer. A lot of people seem to want to meet Jesus, which is legit, although they conveniently forget to set aside time to learn Aramaic first. My own choice would be the 1920s. They were in the middle of a post-war cultural revolution — it was the golden age of the silver screen, Dadaism was turning into Surrealism, you couldn't sneeze without hitting ten radioactive consumer products, and they spoke English. The sheer amount of cool stuff going down made it a great place to set Radium Baby. The only problem for an aspiring alcoholic like me is that it's also boom-smack in the middle of the American Prohibition.


But the characters in Radium Baby don't let that stop them. You could always throw a fuzz junket on bathtub moonshine, or else get a bit squiffy on giggle water at the blind tiger. My favorite Prohibition-era cocktail has to be the Sidecar — an intoxicating mix of two parts Cognac, one part Cointreau, and one part lemon juice, served with sugar on the rim. I drank at least four of these (I lost count) as research for this article, and I can confirm that by the end of the night I'd completely forgotten that it wasn't actually 1927.


The Sidecar may have been a bit frou-frou for Prohibition tastes, though, especially as it was a European cocktail and all those fancy brandies were hard to come by. Herbie Wise would have liked them, I think, because he has a taste for the finer things in life. What really fuels a public drunk like Adrian Ember, though, is gin. This makes the Martini the cocktail of choice for the adults in Radium Baby. You take your vermouth, shake it up in the cocktail shaker enough to coat the ice, then pour it out. Then you pour in your gin, shake it again, and pour. Garnish with green olives. I have a passionate love for salt, so the dirtier the Martini the better. Also, don't let any unlicked rube tell you it's one part vermouth to six parts gin — too much vermouth is the quickest way to ruin a perfectly good Martini. Winston Churchill said the best way to add vermouth to your Martini was simply to raise your glass in the direction of France.


While Ember and Wise like a tipple, Mrs. Cholmondeley is a die-hard teetotaler. Even she, however, seems to have her own unwitting crutch in the form of June Kennedy's Prune Remedy. This Prune Remedy was inspired by a few real health tonics from the time, but particularly Lydia E. Pinkham's Vegetable Compound. Pinkham's Compound contained a good wallop of "medicinal" alcohol, which garnered it an unexpected level of popularity in the Prohibition. There are endless testimonies in Mrs. Pinkham's advertising from housewives whose kids are driving them nuts, but after a bottle or nine of Vegetable Compound they feel right as rain. Pinkham's Compound still turns up in pop culture from time to time, in songs like "Lily the Pink", or as Ephraim's Extract in a recent episode of Quick Draw.


If your blood runs more towards the healthy side of things (and if it does, I can't think why you're reading anything I've written), then your 1920s self might have downed a few radioactive health tonics. Yes, people in the '20s were drinking radioactive water, often every day under the misapprehension that it would cure them of wambling trot or the strong fives. In Radium Baby Gloria drinks from a Revigator — a household radioactive tank which you'd fill with water to be steeped in healthy radioactive rays. For good measure these things would also leech arsenic, lead, and uranium into the water. Over three years one man in real life drank 1,400 bottles of a radioactive tonic called Radithor, and he swore it did wonders for his health right up until the day his face fell off. He had to be buried in a lead coffin.


Valerie and Alexander Pepperpot also partake of a goodly dose of radium in the form of a radioactive duck. The dish is a party piece that, when prepared properly, will create a chemical reaction that expels air through the duck's throat and makes it quack as it's being carved. There was a little truth-bending here on my part, but the recipe is real — only the recipe was medieval and the secret ingredient was mercury instead of radium. As far as I know there aren't any records of people dying from eating these mercury birds, but then I don't imagine they fared much better than the Pepperpots did.


For those who want to throw their own radium-themed wingding, I'd recommend against irradiating the local poultry. Instead, let me take this back to where it began — booze. A great radium-themed drink is the Grasshopper, a mix of one part cream, one part Crème de menthe, and one part white Crème de cacao. You wind up with a lurid green cocktail that is absolutely delicious. Here's mud in your eye, fly-boy.


Thanks for stopping by to share your food for thought, St. John!

4. Voyage

voyage 450RULES OF THE HIGH SEAS

1. Ducks do not make good leaders. Although they are arguably among the most optimistic of species, it is due in no small part to their chronic shortsightedness.

2. However, if you need to be bailed out, a bunny is the first critter you should call.

3. Bears will sink your boat.

6. Deductive Detectives

Image

“Eliminate all other factors, and the one which remains must be the truth,” Sherlock Holmes has said about his method of detective work. In Sylvan Dell’s new picture book, Deductive Detective, our hero Detective Duck shows that he’s learned from the best! He dons his best deerstalker hat, his much-too-big magnifying glass, and solves the case of the missing cake with the same methods the pros use!

That is, a style of logical thinking called “deductive reasoning.” In deductive reasoning, someone finds an answer they’re looking for by first finding out what the answer isn’t. When Detective Duck examines the clues and finds out which of his friends couldn’t have stolen the cake, it leads him closer to what really happened!

Of course, you don’t need a weird hat and a magnifying glass to use deductive reasoning. These methods come in handy every day! If you lose a toy, for example (or car keys), you may make your search easier by determining where the item isn’t.

“Oh yeah,” you may say, “I didn’t bring it to my friend’s house; I wasn’t holding it when I walked to the living room, or landed on the moon. I wouldn’t have brought it to my parents’ room or under the ocean or into Mordor.” By deciding where you shouldn’t look, you now have a better idea of where you should.

This kind of logic process happens throughout the day, sometimes without you even being aware of it; you might say your brain is always on the case as much as any detective!

Apply deductive reasoning the next time you’re in the bookstore: subtract the books that don’t meet the highest educational standards, offer pages of activities and facts, offer online supplements, are fun to look at and fun to read! You’ll be left with books by Sylvan Dell like The Deductive Detective!

10. Ducklings on the Move

In anticipation of yet another upcoming move (just a short, local move this time), I started designing a postcard to send out once we're settled at our new address:
I think I'm setting myself up for a serious challenge with all the ripples in the water those little ducklings can't help but generate. But for the opportunity to illustrate ducklings in all their irresistable cuteness, hopefully the challenge will be worth it!

11. On the Move

Our final moving date is just a little over a week away and there's still a lot to do. I need to put in change of addresses with various places, set up phone and internet service at our new home, and gather up a bunch more book boxes for our substantial library. But, I do, at least, have my painting all finished and ready to be made into postcards:
I think I'm probably going to post this one for sale on my Etsy shop, but I think it might be best to hang on to it until my postcards are finalized. So, if you're interested, check my shop in maybe three or four weeks. I'll update here with a direct link too when it's available.

13. SkADaMo Day 8

When I was in elementary school… a gazillion years ago, we used to do this drill called “duck and cover.” You’d be in class, minding your own business, when a scary, air-raidy sounding alarm would go off. You were then expected to drop down to the floor, crawl under your desk and cover your head with your hands. This was a drill designed to protect you against a nuclear attack.

You heard me.

A nuclear attack. Duck and Cover. Mmmm hmmmm.

I guess they figured it was an easier position to be in to kiss your tookus good-bye.

Anywho, this here is a kinder, gentler, sillier take on the theme… probably just as effective too.

So, yeah, keeping up with the SkADaMo and the PiBoIdMo as well. Feeling pretty pleased with my bad self.

15. A duck walks into a bar…

©2012 Sparky Firepants Images®A duck walks into a bar, approaches the counter and orders a sandwich. He says to the bartender, "Listen, I'm a bricklayer on the construction site nearby. The work will last for some time and I'll be coming here every day around lunchtime for a sandwich. How about a discount?"

The bartender, shocked as he has never encountered a talking duck before, agrees to give the duck a small discount for his daily sandwiches.

The duck takes his sandwich, pays, thanks the bartender and goes out.

The bartender immediately calls his friend who owns a circus:

"Listen, there's a talking duck coming to my bar. Come tomorrow around lunchtime, you gotta see this for yourself!"'

So the next day the circus owner waits in the bar. Sure enough, the duck goes in, jumps on the barstool and orders a sandwich.

The circus manager overcomes his awe and says:

"Hello sir, I'm a circus owner and I want to offer you a job. I can give you whatever money you want, plus a company car, a cell phone, best hotels. Really,  whatever you want!"

The duck considers his offer for a moment and says:

"So you're a circus owner, right?"

©2012 Sparky Firepants Images®"Right."

"And your circus is one of those big tents, right?"

"Right."

"With a sandy arena in the middle?"

"Yes."

"And with rows of seats around?"

"Of course."

"So what the heck do you need a bricklayer for?"

My dad sent me this joke last week. I just couldn't resist illustrating the duck.

16. Duck, Death and the Tulip

My sister was staying with me last weekend and she asked what was that strange picture book in my office. Displayed on my shelves are The Long Journey of Mister Poop, Pat the Beastie, and The Festival of Bones, among others, so I needed a bit more than that to answer her. Turns out she was referring to Duck, Death and the Tulip, a book I intended to review but hadn't gotten around to yet.


The reason is that it's not your usual picture book, and I wanted to do it justice. The story is simple. Death, wearing a fashionably long plaid coat and bearing a black tulip, comes to stay with Duck. Understandably nervous, Duck asks, "Are you going to make something happen?" But no. "Life takes care of that," Death tells her. The two pal around, going to the pond, perching high in a tree. Duck wonders about dying and Death listens to her speculate. Winter comes, and one night Duck lies down. She does not get up. Death gently places her body in the river, the tulip resting on her chest.


The last lines are:

For a long time he watched her.
When she was lost to sight, he was almost a little moved.
"But that's life," thought Death.

Written and illustrated by Wolf Erlbruch, a German author, (and beautifully translated by Catherine Chidgey), the book's simple text and sparse, elegant illustrations combine to create a moving yet unsentimental treatise on death. It also has a sly, deadpan humor throughout, as when Duck first notices Death's presence. "Duck was scared stiff, and who could blame her?"

The book is not for every child, but I so wish it was around when my daughter was six or so. She went through a stage when the thought of death panicked her, just looking at her reflection in the mirror could set her off. This book, with its calm, unblinking look at death, might have eased her fears and helped our discussions. Who knows? She may still get a copy.

17. Puppicasso Predictions #183

July 1, 2012…. Happy Mid Year!

This is exactly the midpoint of this year.  Most of us only make New Year’s Resolutions; or really attend to projects at their beginning point; or only have great starts to their races –

but Puppicasso knows that the hinge of everything lies in survival of getting through the bend of the middle.

To that he asks me, “What’s your mid-year resolution?”  He never waits for my response to any question since he has other needs at present, always at present.

Those needs take us to the outside, and that’s where we see them, the unexpected guests…

ducks in the alley in the Valley.

Puppi surveys the pair of Quacks.

I have seen ducks walking around before, but never in the civilized wild, only in parks or in Memphis at the Peabody Hotel, but never casually strolling.  And indeed never in an alley.

So Puppi and I follow the pair of ducks to the midpoint of the alley, I think they got wind of us, so as not to disturb their unique path, we turned back around and ventured elsewhere for his business, which included the usual mischief of barking at Shadow and finding a compost heap to do a quick face rub in.

http://www.youtube.com/watch?v=jgM_wycelGw&feature=youtu.be

By the time we got back, the ducks were at the top of the alley again, where we found them the first time.

Maybe they are in purgatory, but more likely they are at their midpoint.  Puppicasso says that I can give myself a break at my midpoint –  I don’t have to meet my New Year’s goal, simply start a Mid-year one.

Thanks Puppi, I needed that do-over.

18. Illustration Friday: “Lonely”

During a walk by the water yesterday, I stopped to watch the various birds search for their evening grub. A tall, slim heron, was idling along in the shallow waters on his own, while nearby were ducks and gulls in pairs or groups. And the ducks and gulls were often intermingled with each other. So I imagined what the plight of this heron would be if he were to join in.  He would certainly have some struggles to interact, as he towered at least a foot above the other birds. And so I figured it might be a lonely experience, to be in the midst of a group where you towered over everyone else.
