Right Brain

Those with a right-side dominant brain depend more on visual references for understanding and are often times visual learners.
They are more emotional, swayed by feelings, and are able to better understand and reflect on these feelings. Furthermore, right-brained thinkers are very intuitive and curious about the world.
Finally, as a down side, they tend to be disorganized, lacking in time-management, and unable to prioritize well.

Abstraction = Right Brain

Right brained people may lean more towards abstract art, because of its lack of order and disorganization. Abstraction also gives no boundaries, so it can be considered more ‘outside-the-box’, or creative.
Abstract art is also known to portray emotion, even with no hard visual evidence. A right brained person may more easily be able to pick up on an abstract piece’s deeper meaning.
