VISUAL PERCEPTION: NEURAL SELECTIVITY

ASSIGNMENT NO LESS THAN 300 WORDS

Many people wear glasses to compensate for the fact that the optical system of their eye does not focus a sharp image on the retinas. Once you have reviewed the videos below, discuss at least three of the disorders of focusing. Be sure that you are discussing the complete epigenetic origin which should include a discussion of the genetic/biological origin and the environment influence related to these disorders of focusing. Include in your discussion the impact of culture in the development of the optical system at various stages of the lifespan. Support your belief and use specific examples.

PSYC304| LESSON 3: VISUAL PERCEPTION: NEURAL SELECTIVITY

Introduction
Topics to be covered include:

Lateral inhibition
Single fibers of an optic nerve
The role of feature detectors in visual information processing and perception
Where information goes when it is processed and sent to the brain
How forms of visual agnosia show us the importance of parts of the brain
Why it is important to understand distributed representation
In this lesson, we will look at how the visual systems identify and process information in greater depth. Light is processed and changed as it moves through visual systems to reach the brain. The information is then interpreted by the brain, meaning the exact visual stimulus initially encountered as a distal stimulus is not completely the same once it is processed by the brain. This lesson will explain the different processes that occur and move the infor
