Can you see optical illusions

While it may be very difficult, you can probably get her to switch directions spontaneously. Try looking at the figure and then blink; she may appear to change directions immediately after you blink. Another strategy is to focus on a specific part of the figure. In reality, the spinning dancer illusion is related to a bistable perception in which an ambiguous 2-dimensional figure can be seen from two different perspectives.

Because there is no third dimension, our brains try to construct space around the figure. People typically see the clockwise variation, which research suggests can be attributed to a tendency to assume a viewpoint from above the figure as well as a tendency to perceive movements of the right as opposed to the left foot.

The oblique lines look as if they are crooked and will diverge. In reality, all of the oblique lines are parallel. Much like the Muller-Lyer and Herring illusions, this optical illusion demonstrates how the background of an image can distort the appearance of straight lines.

First, the angle of the short lines compared to the longer lines creates an impression of depth. One of the lines appears to be nearer to us; the other farther away. Another possible explanation is that the brain attempts to increase the angles between the long and short lines. This results in distortion as the brain tries to bend the lines away and towards each other.

Interestingly, if the color of the lines is switched to green and the background to red, the effect completely disappears as long as the two colors are of equal brightness. In the Ames room illusion, two people standing in a room appear to be of dramatically different sizes, even though they are the same size. The image above was captured by a visitor to the "Ames room" in the Villette science museum in Paris, France and uploaded to Flickr, a photo-sharing website.

In the room, the individual on the left appears to be very tall, while the person on the right looks very small. In reality, both people are of approximately the same height and size.

The effect works by utilizing a distorted room to create the illusion of a dramatic disparity in size. While the room appears square-shaped from the viewer's perspective, it is actually has a trapezoidal shape. The woman on the right hand side of the image above is actually standing in a corner that is much further away than the woman on the left. The illusion leads the viewer to believe that the two individuals are standing in the same depth of field when in reality the subject is standing much closer.

The effect can be observed in a number of films, including The Lord of the Rings trilogy. Note the early scenes in The Fellowship of the Ring where the effect is prominently used to make Gandalf appear larger than the hobbits. You can see more examples of Ames rooms in these YouTube videos.

In the Ponzo illusion, two identically-sized lines appear to be different sizes when placed over parallel lines that seem to converge as they recede into the distance.

In the image above illustrating the Ponzo illusion, the two yellow lines are the exact same size. Because they are placed over parallel lines that seem to converge in the distance, the top yellow line actually appears to be longer than the bottom one. The Ponzo illusion was first demonstrated in by an Italian psychologist named Mario Ponzo.

The reason the top horizontal line looks longer is that we interpret the scene using a linear perspective. Vehicles 'Disappearing' from the bridge has left people puzzled! Take a look at the video: Yes, the traffic just disappears.

Although there is no single reason illusions take place, Martinez-Conde offered another possible explanation. The brain is a limited structure with limited resources, including its number of neurons, wires, and neuronal connections, she suggested. Color, motion, shape and the amount of light that hits your eye are just a few of the factors that might cause you to see an illusion.

Some people like to design new illusions and, in fact, there is an annual international contest to recognize the best -- and most novel -- visual illusion of the year. First place this year went to an entry called " The Break of the Curve Ball ," which depicted the path of a spinning disk and helped illustrate why the abrupt shift of this pitch is so good at fooling baseball hitters.

No doubt, the lessons learned from illusions extend beyond the baseball diamond -- and deep into your mind. We'll notify you here with news about.
