· Describe the three things John can do in his drawings to convey depth convincingly.


To convey depth, John should use the similarity principle of Gestalt. This, along with the viewer’s proximity, allows them to see the individual pieces

as part of a larger pattern (Goldstein, 2015). There are a few ways to convey depth, such as position, edging, size, and overlapping to name a few. In art, when drawing in a realistic style, it is helpful to draw from direct observation or by using reference images. 3D images always display depth in a painting. Size of a drawing would create a sense of space and adds dimension. In essence, the main key to creating depth in a painting is to use multiple methods to create a 3D look.


Explain how Gestalt principles can be applied to everyday and real-life vision perceptions.


Humans, according to Gestalt psychologists, prefer to view objects as complete rather than focusing on the gaps they may include. When specific rules are used, individuals prefer to arrange visual components into groups or unified wholes, according to Gestalt theory (Goldstein, 2015). The Gestalt principle has three general rules: objects are viewed in their most basic form; people instinctively follow lines or curves, and the mind will fill in details that aren’t present (Goldstein, 2015). Gestalt theory can even be applied in real-life. For example, you can use the gestalt theory to design websites. This gives the site a more aesthetic appeal and attract more people to it. Gestalt techniques can also be used in therapy by helping the therapist detect issues that need solving. Gestalt psychologists are also trained to look out for specific language patterns while their patient speaks (Clarke, 2021).

Consider a community where most people have achromatopsia.

Describe this vision disorder and its causes.

Achromatopsia is characterized by reduced visual acuity, pendular nystagmus, increased sensitivity to light (photophobia), a small central scotoma, eccentric fixation, and reduced or complete loss of color discrimination (Khol & Wissinger, et al., 2004). Defects in one of a few genes cause achromatopsia. The CNGB3 and CNGA3 genes are the most prevalent genes linked to the disease; mutations in these genes account for roughly 75% of cases. GNAT2, PDE6C, and PDE6H mutations can also cause the illness. Color discrimination is impaired in all people with achromatopsia (achromats) along all three axes of color vision, which refers to the three cone classes: the protan or long-wavelength-sensitive cone axis (red), the deutan or middle-wavelength-sensitive cone axis (green), and the tritan or short-wavelength-sensitive cone axis (blue) (Khol & Wissinger, et al., 2004). Individuals with limited achromatopsia have less severe visual symptoms.


· Based on what you know about rod and cone vision, explain how the community could be modified to compensate for this vision disorder.


To compensate for this vision disorder, Dark or special filter glasses or red-tinted contact lenses reduce photophobia and may improve visual acuity. Low vision aids include high-powered magnifiers for reading as well as digital/electronic devices (Khol & Wissinger, et al., 2004). It is also possible to ensure that others are aware of the illness so that those who suffer from it are not discriminated against. Children with the disorder should be seat in from of the classroom to get maximum benefit of magnifying devices.
