Synesthesia is a completely different way of thinking. Instead of simply seeing something in their minds, these gifted kids experience a crossing of their senses. They may smell music, for example, or hear colors. This form of giftedness stimulates one sense that is seemingly unrelated to another in a non-gifted kid. Do your children have synesthesia? Here are some signs to look for:
Listening to music while they work
While a regular child may find music distracting while trying to do their homework, synesthetes can often get into a flow state while hearing melodies and sounds. These gifted kids may listen to songs without words in any genre, from classical to dubstep, and find that it increases their productivity.
Not knowing they're different
A study published in Science Direct noted that synesthetes tend to not know that they think differently. Because they've had this conjoining of the senses for their whole lives, they don't realize others don't process stimuli in the same way.
Everything relates to colors
Synesthetically gifted children may see a black number six or white letter "a" and perceive it to be an entirely different hue. This is not only true of one specific numeral or letter; instead, every individual number or letter has its own corresponding color. You can show your kids flashcards with black letters, for example, and if they have synesthesia they will tell you they see a hue that is entirely different than what you can see.
Their responses stay the same
Play a piece of music for your gifted kids. Ask them to write down what they see while they listen. Repeat this activity a week later. A child who has synesthesia will see the same thing they did the first time when they listen again in the future. This may mean visions of changing colors or possibly even noticing specific words or letters that stand out in the lyrics. When someone without synesthesia listens to a song they likely won't have the same answer from one week to the next regarding what they see. The lyrics change meaning based on the listener's circumstances. This won't be true, however, for a gifted child who has synesthesia.
Synesthetes are particularly interested in creative endeavors like drawing, painting or playing music. Parents can encourage them to undertake these activities as their special abilities may make them prone to success in their chosen artistic field.
