Drawn over a 100 years and used by American psychologist, Joseph Jastrow in 1899 to make a point about perception, the image recently hit the internet again drawing mixed reactions.

In the last couple of days, the image above has left cyberspace in rhetorics - is the image that of a duck or rabbit?

While some immediately see a duck, others see a rabbit and others yet again see both.

Ironically, the sketch was drawn over a 100 years ago and 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.

Jastrow's research was based on how quickly one can see the second animal and how fast participants could change their perception of the drawing to switch between the two animals.

According to the research, the faster you can do this this, the quicker your brain works and the more creative you are.
