1. The science of illusions and the Crazy Kitchen

1 T0 Perceptions and Illusions World of Illusions Un monde d’illusions

1 ST0 What we perceive is not always reality

Don’t believe everything your senses tell you

Ne vous fiez pas toujours à vos sens

1 L0 text ● Our understanding of the world around us is affected by how we sense and receive information and how our brain organizes, processes and interprets this sensory information.

● Our senses can be distorted which changes our view of the world around us.

Listen carefully. Look closely. Take a good whiff. Our senses tell us all about the world around us. But can we always trust that information? Is the world we see, hear, smell and feel exactly as it seems? Prepare to enter a world of illusions ….[45 words]

Tendre l’oreille, ouvrir l’œil et les narines : nos sens nous aident à comprendre le monde qui nous entoure. Mais peut-on toujours s’y fier? Ce que nous percevons par la vue, l’ouïe, l’odorat et le toucher est-il fidèle à la réalité? Préparez-vous à entrer dans un monde d’illusions… [48 mots]

1 T1 What’s happening inside the Crazy Kitchen?

Crazy Kitchen Crash Course Que cache la Cuisine bizarre

1 ST1 Your senses are being fooled.

Getting Mixed Messages Quand les sens se contredisent

1 L1 ● Our senses can be tricked when they get conflicting information from their body's balance-sensing organs.

● As you walk through the crazy kitchen your eyes see the room as straight, and tells your brain that you are standing in a flat room.

● The room is actually tilted on a 12 degree angle – which is

What’s happening here? Your senses get tricked when they receive two different messages at once. The Crazy Kitchen looks level, so your eyes tell your brain you’re standing in a flat room. But the room is actually tilted, which is what your body’s balance systems are telling your brain. Your brain gets confused, so you get dizzy.[61 words]

Que se passe-t-il ici? Lorsqu’ils reçoivent deux messages différents en même temps, les sens se trompent. Comme la Cuisine bizarre semble être à niveau, les yeux signalent au cerveau que la surface est plane. En réalité, la pièce est inclinée, et c’est ce qu’indique au cerveau le système responsable de l’équilibre appelé système vestibulaire. La confusion ainsi créée peut mener à des étourdissements.

2.1 L2 ● In the 1800s scientists started studying perception in the lab, this was called experimental psychology

● It was a controversial science at that time.

● Researchers studied the basic elements of sensation and perception such as sounds, colour, touch,

In 1891, the University of Toronto opened Canada’s first psychology lab. Scientists in this lab studied how our minds change the information we receive when we see, hear and touch. Since then, many illusions have been developed based on psychological research.[41 words]

En 1891, l’Université de Toronto a ouvert le tout premier laboratoire de psychologie du Canada. Les scientifiques y étudiaient la manière dont notre esprit transforme l’information qu’il reçoit par la vue, l’ouïe et le toucher. Depuis, des études en psychologie ont permis de créer toutes sortes d’illusions. [47 mots]

2.2 L2 [Explanation]● This illusion

demonstrates challenges in our perception of faces.

● Our brain's ability to recognize faces is affected by the orientation of certain facial features.

● We most frequently encounter upright faces, and our brains have been trained to recognize faces in that

What’s happening here? The eyes and mouth stay right-side up, while the rest of the face is upside down—but we don’t notice. We’re used to seeing facial features in their upright positions, so our brains are trained to recognize them that way. We don’t realize there’s anything strange until we turn the face around. [53 words]

Que se passe-t-il ici? Vos yeux et votre bouche sont restés à l’endroit, tandis que le reste de votre visage est à l’envers. Pourtant, vous n’y voyez que du feu. Pourquoi? Nous sommes si habitués à voir ces traits du visage à l’endroit que notre cerveau les reconnaît de cette façon. Nous remarquons seulement ce qui cloche lorsque le visage est remis à l’endroit.

orientation. ● In this illusion,

the person's eyes and mouth are kept upright while the whole face is inverted.

● Amazingly, people do not notice the inverted details and it looks like a normal upside down face.... until you flip the picture right side up, and it becomes obvious that there is something wrong with the face.

Dawn Hall, 2017-01-19,


FYI, I do not have a published (printed) version of this work, but I have brought some minor typographic changes in the interest of consistency with the rules that we are applying in the exhibits. These little differences could change anyway from one edition to another. However, I recommend checking a few other details against published version (namely: “noire!” or “noire :”, “où” or “Où”). Would you like me to do that?


3.1 L3 [Explanation]What’s happening?

● Typically, when we speak, we hear ourselves speaking almost immediately, and our brains use this information to continue speaking.

● The speech jammer records your voice, and plays it back to you – but with a longer delay than usual.

● This delay (in auditory feedback) makes it difficult for your brain to process this information, which makes continuing to

What’s happening here? Usually, when you speak, you hear your voice right away. Your brain uses this information to continue speaking. But the speech jammer delays the playback—confusing your brain and tying up your tongue. Scientists use this type of tool to study stuttering.[48 words]

Que se passe-t-il ici? Habituellement, vous entendez votre voix au moment même où vous parlez. Le cerveau utilise ce que vous entendez pour vous permettre de continuer à parler. Mais le brouilleur de discours ralentit le retour d’information. Il crée ainsi une telle confusion dans le cerveau que vous ne pouvez plus parler. Les scientifiques utilisent ce genre d’outil pour étudier le bégaiement. [63 mots]

Dawn Hall, 2017-01-23,

I think this is much better.


How about: “Que se passe-t-il? Habituellement, vous entendez votre voix au moment même où vous parlez. Votre cerveau utilise ce que vous entendez pour vous permettre de continuer à parler. Mais le brouilleur de discours ralentit le retour d’information. Il crée ainsi une telle confusion dans le cerveau que vous ne pouvez plus parler. Les scientifiques utilisent ce genre d’outil pour étudier le bégaiement.” [62 mots]Detail: Because this wording is longer than the original that was proposed and because it is somewhat complex, I made some changes for accessibility: I used “vous” for simplicity. I used “ce que vous entendez” because it is simpler, conceptually, than “information sonore”


Langue (tongue), not parole, not langage. As an example of an expression that associates the tongue (the organ) and speaking in French, one can say that “les langues se délient” (meaning that people are starting to speak up).

3.2 Reverspective

3.2 T2 Reverspective Reverspective Inverspective

3.2 ST2 Looking inside out Looking inside out Un trompe-l’œil sur tous les plans

3.2 L2 ● Originally created by British artist Patrick Hughes

● Uses geometry and linear perspective to make it seem that the objects in the painting are viewed in the reverse depth.

● Perspective has been an important part of creating three dimensions in art for centuries and is being reversed here.

What’s happening here? Artists use perspective to make objects in flat works of art seem closer or farther away. Here, the artist is playing with 3D shapes and angles to create “reverse perspective”—making closer things seem farther away and vice versa.[45 words]

Que se passe-t-il ici? Les artistes utilisent la perspective pour donner l’illusion que des objets sont près ou loin, même en deux dimensions. Ici, l’artiste joue avec des formes et des angles en trois dimensions pour créer une « perspective inversée » : les objets rapprochés semblent loin et vice versa. [51 mots]

3.3 L3 [Explanation. On screen or on the wall - could be at beginning or at end]

What’s happening?● How we perceive

smell is influenced by our past experiences, our culture and the number of olfactory receptors we have in our noses.

● When we smell

What’s happening here? When you smell something—whether it’s fresh-baked cookies or spoiled milk—receptors in your nose detect a chemical and send the message to your brain. But there’s more to smelling than just chemistry. Your culture, memory, gender and personal experience influence the way your brain interprets the signals from your nose.[57 words]

Que se passe-t-il ici? Quand on sent une odeur, comme celle du lait caillé ou des biscuits sortant du four, des récepteurs situés dans le nez en captent les éléments chimiques et envoient un message au cerveau. Mais la chimie n’explique pas tout. Culture, genre, souvenirs, expériences personnelles, tout ça influence la manière dont le cerveau interprète les signaux venus du nez. [62 mots]

18


something, it’s because chemicals have bound to the receptors in our noses, which sends a signal to our brains.

● Humans have millions of sensory neurons at the back of the nose, each which contains one of 400+ different scent receptors.

● Smell recognition and processing is directly related to the limbic system – which is also involved in emotional responses and long term memory, which is why certain smells can be associated with vivid past

5.1 L2 [Explanation]

● The trick here is revealed when you look from the other angle.

● It all depends on how you look at the image.

● Your brain searches for familiarity and will stitch together a few shapes, even if the complete image doesn’t exist.

What’s happening here? Your brain likes to find familiar patterns, pictures and designs —even where none actually exists. From most angles, this looks like a random collection of shapes. But from just the right perspective, your brain sees something here that makes sense. It stitches the shapes together to create a complete image. [53 words]

Que se passe-t-il ici? Le cerveau aime trouver des images et des motifs familiers, même s’il n’y en a pas. De plusieurs points de vue, cette image n’est qu’un ensemble de formes aléatoires. Mais quand on se place exactement au bon endroit, le cerveau arrive à faire sens de ces formes et à les rassembler en une image complète. [60 mots]

what we see depends on the way the object is lit.

● Can’t see anything? Try blinking

look like this picture is moving? Well, it’s not. As you look at the image, your eyes are making tiny movements—so small that you don’t notice. Your brain thinks it’s the picture that’s moving instead. Japanese psychology researcher Akiyoshi Kitaoka has created many illusions like this one. [56 words]
