Originating from Gestalt theory, a Gestalt shift is when someone’s interpretation of his experience changes from one thing to another. The famous duck/rabbit illusion provides a simple example: the moment one’s brain switches from seeing the image as a duck to seeing it as a rabbit represents a Gestalt shift.

The central principle to the Gestalt theory was neatly summarized by the Gestalt psychologist Kurt Koffka: “The whole is other than the sum of the parts.” The human eye and brain perceive a unified shape in a different way to the way they perceive the individual parts of those shapes.

Gestalt psychology focuses on how our minds organize and interpret visual data. Based upon this belief, Wertheimer along with Gestalt psychologists Wolfgang Köhler and Kurt Koffka, developed a set of rules to explain how we group smaller objects to form larger ones (perceptual organization).

Gestalt techniques were originally a form of psychotherapy, but are now often used in counseling, for instance, by encouraging clients to act out their feelings helping them prepare for a new job.

The meaning of the rabbit duck illusion says that people who are able to see both animals easily are more creative in general. Most people can see the duck, but have difficulty seeing the rabbit — so if you can see both, congratulations! You probably have a greater sense of creativity than most people.

What you see (and how fast you see it) could indicate how quickly your brain works – and how creative you are. The duck-rabbit drawing was first used by American psychologist Joseph Jastrow in 1899 to make the point that perception is not only what one sees but also a mental activity.

The rabbit–duck illusion is an ambiguous image in which a rabbit or a duck can be seen. The earliest known version is an unattributed drawing from the 23 October 1892 issue of Fliegende Blätter, a German humour magazine.

With its head tilted back, it’s easy to mistake the raven’s beak for bunny ears and the top of its head for a nose. But a few details—like its translucent nictitating membrane that closes across the eye horizontally—indicate that it’s really a bird.

Bunnies have been with humans for a longer time and are much better pets than birds are. Their vet care is also cheaper than a parrot’s and owning a bunny is slightly cheaper than owning a cat or dog, which means they are much cheaper than a parrot. Bunnies are overall more suitable as pets. Both make good house pets.

Rabbits are small mammals in the family Leporidae (along with the hare) of the order Lagomorpha (along with the pika). Oryctolagus cuniculus includes the European rabbit species and its descendants, the world’s 305 breeds of domestic rabbit.

In the case of this viral video, the animal appears to be a bird due to the positioning of the supposed “ears” of the “rabbit.” Rabbits’ ears are on the sides of their heads, not one behind the other. The “ears” also don’t appear to be fuzzy, indicating that the animal is indeed a raven or crow.
