The ambiguous images force the brain to create a more personal interpretation of the work. The blurry shapes and splashes of colour mean that, people have to draw on their own memories to fill in the missing visual details.
People preferred impressionist art over cubism, Renaissance or Japanese art, so each painting is interpreted slightly differently by each individual, making the experience more visceral.
“Or visual system reflexively fills in expressions and mood, going deeper into our mental state than any fully explicit painting cloud”
These paintings may also be attractive because their blurred forms speak directly to the amygdala, a brain region involved in the processing of emotions.
The amygdala responds more enthusiastically to fuzzy faces than to sharp versions of the same image, the blurred images seem to have privileged access to the subconscious.
The brain regions typically associated with conscious image-processing were noticeably subdued when subjects looked at the blurred images.
The texture are crude dabs and stokes of impressionist art may be enough to delay our conscious response to the content of the painting, allowing the emotional centres to fire more frequently. – Patrick Cavanagh
Jessica Griggs said, when it comes to understanding the brain’s vision system, artists are may ahead of neuroscientist.
The ambiguity arises because our brain’s perception of the world is a rough approximation of reality. Our brain has to fit within our cranium so it cannot process everything that is out there, so the brain takes short cuts, sampling only the most significant parts of the scene, e.g., the contours, the edges, the corners of objects. The rest is typically built around our memories of past experience and our expectations of what should be there.
This is particularly noticeable when the images are vague. There is a lot of information which needs to be filled in, and the brain can fill it in a number of different ways.
Your previous experiences might determine whether you seem the figures, we evolved to make sense of partial visual details, and to make out a coherent picture even in poor lighting. –Martinez Conde
Illusions are by-product of this, they represent the dissociation between objective reality and subjective perception.
