The static diagram moves because the pressure is high? Not too! About "Psychological stress test Diagram" rumor

Gossip: People's psychology in varying degrees of change, the desire to start randomly. The psychological test proves that the following pictures are related to each person's psychological endurance, the stronger your psychological endurance, the slower the picture rotation. The United States used this as a psychological test of the suspect, he saw the picture is high-speed rotation, and most of the elderly and children see that this picture is still. Please do your own measurements. See your psychological endurance is how big, to treat oneself better adjust mentality ...

After reading this seemingly rich philosophy of the text, and then look at this magical picture, some people surprised, some doubt, someone smiled, someone panicked ... Perhaps more people are wondering: I consciously is not the glass heart, recently also did not have any pressure, how also will feel it in turn? Or find someone else to see.

So, spread wildfire, everyone will come to watch this convenient intuitive "psychological stress test Map"-so, this rumor on the network has been widely circulated for nearly 10 years. However, even if spread widely, gossip is always a rumor.

Truth: These pictures are designed to create a dynamic illusion that the diagram is moving very normal, and the size of the psychological pressure has nothing to do.

The first reaction of many friends is to check if the image is animated. However, as a few of the introduction of the truth, the picture is indeed static. The following picture is the same:

But don't worry about it. The stress is too great to start worrying about your mind being controlled. Although the various forms of these pictures, "movement" way is also different, but no matter whether the rotation or the rolling fluctuations, the use of the principle behind, are consistent.

What we observe is a visual illusion called the "peripheral Drift illusion".

The Peripheral Drift illusion (pdi,peripheral drift illusion) is an abnormal motion illusion that can be observed with edge vision (peripheral vision). Psychologists Faubert and herber the concept of a peripheral drift illusion for the first time in 1999, and as early as 1979, Fraser and Wilcox reported this phenomenon, typical of the following patterns. Thus, this illusion is also known as the Fraser-wilcox Illusion (the predecessor of the first picture).

In 2003, Akiyoshi Kitaoka of the University of Japan's Gamming and Lu farmland (Hiroshi Ashida) of Kyoto University presented a method to enhance the illusion of peripheral drift. They pointed out that the step-type brightness change is more able to reflect the surrounding drift illusion than the smooth brightness transition, and the fragment edge is better than the straight long edge. The design based on these optimization theories greatly enhances the effect of the peripheral drift illusion.

In September of the same year, as an optimized example of the peripheral drift illusion, the North gang used static repetitive asymmetric patterns (raps,repeated asymmetric patterns) to design the "spiral snakes". This eye-catching work has made him famous and aroused interest in studying the illusion of peripheral drift. Research has shown that the proportion of people who are unaware of the illusion of peripheral drift is only about 5% per cent of the population-so it is normal to see a "Dance of snakes", which does not mean how much mental stress or how fragile your heart is.

Along with the research of the peripheral drift illusion in the field of psychology and biology, the factors that influence the illusion of the peripheral drift and the neurobiological basis of perceptual illusion are revealed gradually.

It's not hard to find that when you look at one of the snakes in the snake, the snake doesn't rotate. And every time you look away, the snake starts spinning again. The effect of the peripheral drift illusion is particularly noticeable when blinking frequently or the sight continues to shift. This suggests that refreshing the image to the retina is very important to the perception of the peripheral drift illusion.

In the 2005, the primary visual cortex (V1) layer and neurons in the middle temporal region (MT) were used to study Conway and others reveal the neural basis of the peripheral drift illusion--the response time of neurons with directional selectivity is different to the contrast stimuli, and the visual neurons respond to high contrast stimuli faster. In the same year, Backus and Oruç of the University of Pennsylvania presented a perceptual model of peripheral drift illusion. They point out that color and contrast are key factors in increasing the illusion of peripheral drift. In 2006, the Northern gang found that the most intriguing color combinations in the surrounding drift illusion were blue-yellow and red-green, and the "snake" began to have a variety of more colourful versions.

Driven by these studies, the image of the surrounding drift illusion has become more sophisticated and diverse. With the highlighting and shading settings, the Northern gang also made a pattern with a similar 3D effect. Although the pattern of the surrounding drift illusion is gradually multiple, its essence is still an ordinary visual illusion.

The source of

In other words, the false effect is so much, why does the rumor put this kind of picture with the psychological stress test to relate?

The exact reason is also to ask the originator. There are probably several possible reasons for this:

1, the effect of a strong peripheral drift illusion of visual system stimulation misinterpreted as psychological pressure. On the North Gamming home page, the warning notes: "The page contains images of abnormal motion illusions that may make sensitive observers feel dizzy or nauseous." This illusion stimulates the observer and may be misinterpreted as a measure of the observer's mental state.

2, the potential relationship between the age of observers and the illusion of peripheral drift Emily into mood differences. In the 2005 Visual Science Society, a motion perception researcher suggested that the effect of the peripheral drift illusion might be negatively correlated with the age of the observer. This assumption was confirmed in subsequent investigations. Rumors, "Most of the elderly and children see the picture is still." "may be far-fetched about it.

3. Sell products to relieve pressure. In the discussion of the degree of "psychological pressure" from foreign netizens, some people traced the possible source of gossip: A foreign language website used the image of peripheral drift illusion as the "psychological stress test" material at least in 2005. Doubt oneself psychological pressure too big netizen is loved by the operator--they sell buck music under illusion picture.

All in all, whatever causes such rumors, linking the illusion of peripheral drift with mental endurance or stress tests is not only unscientific, it does not conform to the original intent of the illusion designers and the illusion researchers.

In fact, the design, observation of these strange images of the surrounding drift illusion, not to check their psychological status, but more out of a kind of experience and enjoyment of beauty. After understanding the scientific principles behind it, North Gamming's best personal website continues to update his design of the surrounding drift illusion works, constantly shaking the eyes of the viewer.

For the illusion of peripheral drift, scientists have never stopped to study the footsteps, designers are gradually beginning to feel the simple but the effect of the illusion of pile charm. From the illusion of cake to Van Gogh's masterpiece, these gorgeous and strange illusion has been applied to art design, will eventually get rid of the binding of gossip, to the real appearance, return to people's lives.
