A research has come up with findings to suggest that human mind has the ability to reliably sense a change in person's appearance, even when it could not identify what precise changes have taken place. Well yes, this is what the study by University of Melbourne researchers has claimed.

To give you a better insight into the study, a friend of you could realize a change in your appearance, but not be able to figure out that you had had a haircut. The researchers have revealed that this ability of the mind is commonly called as sixth sense, or extrasensory perception (ESP), which is not true.

Lead researcher Dr. Piers Howe is of the view that their study is of its first kind to prove the fact that people have the ability to reliable sense changes that they are not able to identify visually.

"We were able to show that while observers could reliably sense changes that they could not visually identify, this ability was not due to extrasensory perception or a sixth sense", he said.

He said so because the study helped them understand that participants were able to realize a change that they were not able to identify visually, without invoking extrasensory perception.
