What are the basic processes underlying the sense of vision?

Instructions
In our reading this week, we learned about the processes of sensation and perception. Although they are two different processes, one often has an impact on the other. Some individuals aren’t aware of how much they rely on vision or hearing in their everyday lives, versus others who have vision or hearing impairments who may rely more heavily on their other senses and perceive the world differently than others. Please choose ONE option below for either diminishing your vision or hearing with the goal of becoming more conscious of the relationship between sensation and perception.

Note: Please be very careful when performing these activities. I suggest doing them in a familiar environment, such as your home, and having a companion present.

Option 1: Vision
Spend between 15 to 30 minutes “observing” without using your vision. Rely on your hearing, smell, touch or taste (if appropriate) to navigate your environment. During this time try to perform several different tasks that you would normally, such as picking up an object, or if you’re at home try walking to the next room, all while not using your vision. To impair your vision, you can simply close your eyes or wrap a scarf to cover your eyes.

After your observation time is over, please answer the following questions in 2-3 pages.

What are the basic processes underlying the sense of vision?
During the activity, what other senses were you using and how did you use them to accomplish your tasks to perceive the world around you?
What information did you pick up on that you may have ignored if you were using your sense of vision?
Define habituation and sensory adaptation. Provide examples from your observation time of habituation and/or sensory adaptation to support your response.
While this activity was only for a short amount of time, describe how your perception might change if one of your senses was permanently lost.
Option 2: Hearing
Spend between from 15- 30 minutes “observing” without using your hearing. Rely on your sight, smell, touch or taste (if appropriate). You can use earplugs or noise cancelling headphones (if you have them) to aid in diminishing your hearing. During this time try to perform several different tasks that you would normally, such as watching television (muted), or walking outside all while not using your hearing.

After your observation time is over, please answer the following questions in 2-3 pages.

Briefly describe how sound travels through the ear to the auditory nerve.
During the activity, what other senses were you using and how did you use them to accomplish your tasks to perceive the world around you?
What information did you pick up on that you may have ignored if you were using your sense of hearing?
Define habituation and sensory adaptation. Provide examples from your observation time of habituation and/or sensory adaptation to support your response.
While this activity was only for a short amount of time, describe how your perception might change if one of your senses was permanently lost.
