Is Art Done With the Right or Left Side of Your Brain
In 1979, Betty Edwards published the book Drawing on the Correct Side of the Brain, which remains the preeminent book on the subject field of drawing for beginners. In the book, Edwards argues that there are two separate pathways through which the brain processes visual information. The left side is described every bit being analytic, verbal, and numeric, while the right side is holistic, perceptual, and artistic. The central to learning how to describe, according to Edwards, is to suppress the biases and preconceptions originating in the left side of the brain and focus on the more naive, Gestalt approach of the right side.
The method includes the notion of upside-downward cartoon—the idea that when learning to depict by copying, it is preferable to turn the to-be-drawn object upside-down. The result of a 180-degree rotation is to silence the left brain's preconceptions most what the drawn object is supposed to wait like and permit the right brain's perceptual processing and creativity to take over.
Although the upside-downward drawing method has been taught in countless fine art classes, the research on its effectiveness has been less than compelling. For instance, a meta-review of the laterality of creative processes conducted by Dietrich and Kanso (2010) plant no bear witness that the right and left brain hemispheres contribute differently to creativity. Furthermore, the idea that cartoon upside-down objects, including faces, leads to more accurate depictions has not been supported scientifically.
In a recent study, Dr. Jennifer Day and I explored the question of whether naïve participants (not trained in drawing) would produce more accurate face drawings when presented with upside-downwards vs. upright faces (Day & Davidenko, 2018). In gild to generate easy-to-draw faces for the experiment, we constructed a parametric confront space based on 400 existent human faces, which allowed the states to produce a number of unique faces to be drawn. The methodology to generate these faces is described in item in Day & Davidenko (2019).
Participants in the drawing study had xc seconds to describe each of 16 faces, which could be presented upright or upside downwardly. The figure beneath shows examples of drawings of upright and inverted faces, produced past dissimilar participants:

We evaluated the accuracy of each face drawing using four separate metrics:
(1) A physical measure based on the Euclidean distance in face-space between the drawing and the original face
(2) A physical measure based on the angular departure in face-infinite between the drawing and the original face
(3) A perceptual measure of similarity based on similarity ratings from a new group of participants comparing the upright-drawn and inverted-drawn faces (all presented upright)
(four) A perceptual measure of similarity based on similarity ratings from a new grouping of participants comparing upright-drawn and inverted-drawn faces (all presented upside-downwardly).
All four metrics pointed to the same result: Upright (not upside-downwards) drawings were more than accurate. Despite what is suggested by Betty Edwards and the upside-down drawing method, the drawings of upright faces were accounted as more similar to the original faces than the drawings of inverted faces, according to both physical and perceptual measures of accurateness.
What is backside these results?
There may be some actual advantages to drawing upside-down faces—certain biases of what we expect a nose or a rima oris to look similar are likely suppressed when we are drawing upside-downwardly faces that are less familiar to united states. Even so, cartoon upside-down faces also presents disadvantages that may outweigh the advantages. First, your encephalon may notice it more than hard to remember what you are cartoon when you await away from the target to your drawing and back.
Even more critically, yous may notice it difficult to judge how well your drawing is coming out when looking at information technology upside-down. The expertise we have with faces, which allows us to judge whether two faces are similar, is severely limited with upside-down faces. This impairment may interfere with our ability to judge the accuracy of our drawings in existent-time and make the necessary corrections.
All in all, drawing is a complex perceptual and cognitive process that takes years to railroad train. Although turning an object to be drawn upside-down may help in early stages by suppressing visual biases, information technology besides interferes with our ability to remember the to-be-drawn object and judge the accuracy of our drawing as it progresses. The key to improving ane's drawing abilities, then, may be to learn how to suppress visual biases without turning stimuli upside-down, thereby retaining the visual expertise necessary to produce a skilful likeness.
