The secret behind the Mona Lisa is that the “happy” part of her smile is actually buried in a low spatial frequency pattern. So if you’re not looking directly at her mouth, her smile looks cheerful. But when you look directly at her smile, parts of it disappear into the background.

Unique Art Techniques Unlike some artwork of the sixteenth century, the Mona Lisa is a very realistic portrait of a very real human being. Alicja Zelazko of Encyclopedia Britannica attributes this to Leonardo’s skill with a brush, and his use of art techniques that were new and exciting during the Renaissance.

Just by looking at a symbol, we can figure out the associations and meanings that are behind it. The Mona Lisa tells a story without using words. It symbolizes all of Da Vinci’s art and the revolution that he brought about through it. It symbolizes a change in styles and the development of the arts in general.

The purpose of his mirror writing is unknown, but one idea is that it may have kept his hands clean. People who were contemporaries of Leonardo left records that they saw him write and paint left handed. As a lefty, this mirrored writing style would have prevented him from smudging his ink as he wrote.

It’s completely normal for children to write “backward” at this age. In addition to letter and number reversals, some children will truly write in mirror image: going from right to left with all the letters reversed. The more children write, the easier it becomes for them.

For example, case reports have described people who have changed their handedness or have spoken foreign languages during their dissociative states. During an interview with a patient with DID, a surprising talent emerged when she wrote a sentence for the Folstein Mini-Mental State Exam-mirror writing.

It’s not unusual for young kids to reverse letters when they read and write. But when they still frequently write backwards or upside down beyond age 7, it could signal trouble with reading or language. People often think writing letters backwards is a sign of dyslexia, but that’s often not the case.

Writing letters backward and in reverse order, sometimes called mirror writing, may be a sign of a deteriorating brain, but in one woman’s case, researchers found that the unusual condition was actually caused by anxiety.

Mirror writing is an issue that many children face, hence is not specific to children on the autism spectrum. The important question is whether one perceives the image in reverse, or perceives it the right way but makes a mistake while carrying out the action of writing.
