John can use the principles of Gestalt, namely the use of monocular cues, to create depth in his two-dimensional drawing.
Firstly, he can use the knowledge of various monocular cues to create depth perception. For instance, he can use the cues of linear perspective, by drawing objects closer to the horizon relatively smaller. At the same time, he can show that the images which are larger and are horizontally distant from each, are closer to the viewer and therefore clearer (Goldstein, 2015).
Secondly, he can use the principle of similarity by manipulating how and which objects look similar to one another. According to the law of similarity, viewers will perceive the individual elements as part of a pattern or group. And thus, objects which are similar in shape, size, or color can be made to create a sense of depth and the viewer may perceive that there is a relatively shorter distance between similar objects which occur on the same plane compared to the dissimilar ones (Goldstein, 2015).
Thirdly, John can incorporate the monocular cue of texture gradient by portraying the nearby objects in finer details such as rough texture, vibrant and clear color hues, whereas minimizing such details on faraway objects. Texture gradients are grains of an item; it regulates eye movement- in such a way that one sees the pattern nearer to the eye level more clearly than objects or images that are farther away (Goldstein, 2015).
John can indeed utilize the knowledge of Gestalt theorists within his creative works.
People with achromatopsia have a total or a partial absence in their color vision. Individuals with complete achromatopsia can only see black, white, and shades of grey. Whereas, individuals with incomplete achromatopsia can only see some colors but not others. Between 4 and 10% of the people belonging to the Pingelapese island have complete achromatopsia. This disorder is caused by a type of gene mutation that is present in these people (Wise, 2001).
In people with achromatopsia, the cones are non-functional. Cones are responsible for providing daylight vision (vision in bright light), whereas the rods are responsible for providing night vision (low light). Due to this mutation, the phototransduction is affected since the cones cannot react properly to the light., thus resulting in achromatopsia. On a community or societal level, since achromatopsia is inherited by autosomal recessive pattern, if two individuals in which each of them is possessing the mutated copy of the gene mates, then their child, who will possess both their genes will have achromatopsia, if an individual with one copy of the mutated gene mates with an individual who does not have a mutated copy of the gene, then their children will not have achromatopsia as they will inherit only one copy of the mutated gene (NCBI, 2021). We could also be more sensitized and focus on creating more opportunities for people with such disorders. The least is by attempting to reduce the physical/societal barriers and allowing free exploration. Also, creating awareness and attempting to remove the stigma surrounding their disorder is another measure that could be adopted.
