Respond to the following questions in 75 to 150 words each.
1. Differentiate between sensation and perception. Explain the importance of separating these concepts.
The term sensation is used when referencing the process of sensing the environment through taste, touch, sound, smell, and sight (Goldstein, 2014). Moreover, it is the process that occurs once the sensory receptor experiences stimulation, which in turn produces nerve impulses that are sent to the brain to be processed in its raw form, then perception comes into play (Goldstein, 2014). Perception is used to describe the way people interpret these sensations and tries to make sense of everything around them on a daily basis. Perception is the occurrences of the brain

3. As we age or incur visual impairment, we may need brighter light when reading. Explain why this is the case.
As a person ages, the constant need to accommodate when looking at nearby objects such as in reading or doing close-up work becomes more difficult (Goldstein, 2014). The main reason a person may experience the need for a brighter light when they get older is a result of a condition called presbyopia, also referred to as "old eye" (Goldstein, 2014). Old eye describes when the distance of the near point increases as a person ages. According to Goldstein (2014), "The near point for most 20-year-olds is at about 10 cm, but it increases to 14 cm by age 30, 22 cm at 40, and 100 cm at 60" (p. 25). Generally, this change occurs because the lens hardens with age and the ciliary muscles in the eye become weaker, causing great difficulty in vision when looking at objects in close range (Goldstein, 2014).
4. You are shown a picture of an elephant. Explain how that stimulus is processed from the retina to the visual cortex of the brain.
Focusing an image clearly onto the retina is the initial step in the process of vision, but although a sharp image on the retina is essential for clear vision, a person does not see the picture on the retina. Vision occurs not in the retina, but in the brain. Before the brain can create vision, the light on the retina must activate the visual receptors in the retina by a two-element
a. The time (in years) it takes a sample of students to graduate college (Mean)
My grandmother suffered with thyroid and use to always ask me if I had thyroids. I remember a time when she told me to get a quarter and some iodine to put on my stomach above my navel. She told me if it changed colors that I had thyroids. Also, because I felt so drained most of the time and would swell in my body often, she had me to consult with my physician about the matter. My grandmother was a very intelligent woman that was very health conscience about herself and her family.
Some of the current changes that can be seen in regards to prescription privileges include changes in the ways that physicians and mental health professionals are able to prescribe medications to their patients. According to Brenda Smith of the APA (2012), currently patients receive their medications for psychological conditions by a physician usually without having been evaluated by a mental health practitioner according to the CDC. The trend includes individuals to visit their general health practitioners in order to receive psychotropic medications such as antidepressants and anxiolytics. The problem with individuals receiving these medications from other sources include: deterrence
Yes! Education is very important to me because of the way I grew up. My mother wasn’t very educated about children sometimes I think she thought that children should come with a how-to book, which is why my brother and I were put into foster care. I told myself that when I grew up I was going to go to college. I enrolled here at Ashford University on December, 21, 2014 and I’m estimated to graduate on December 3, 2018. My three (3) educational goals that align with education as a core value are Goal A, Do the best to my ability and apply myself to do the work and receive a passing grade. Get a “B” or better. Goal B, Never give up! No matter what anyone says? My final goal C is to finish out with my bachelor’s degree in childcare. With me willpower has a play in all that I do. I have so many people that do not believe in me. They say that because I have a learning disability that I won’t be able to do the work in college. I use my willpower to show them they are wrong. My willpower is
Explain the visual process, including the stimulus input, the structure of the eye, and the transduction of light energy.

-3 x 1.66 pts. = minus 5 pts. = 45 pts. out of 50 pts. = 90%
1. Differentiate between sensation and perception. Explain the importance of separating these concepts. The differences between sensation and perception is that sensation is the elementary elements that, according to structuralist, combine to create perception. Whereas, perception is the conscious sensory experience (Goldstein, 2014). This student has always looked at sensations as those things in a persons’s environment that one can see, hear, smell, touch, taste, and feel. On the other hand perception is how a person’s brain will interpret what is seen, heard, smelt, felt, or touched.

Okay people, try not to laugh too loud, but I thought the bread and wine were called sacraments. Now, I find out that to be politically correct, they are referred to as the elements of the sacrament. As a Baptist, the Lord’s Supper or Communion, which are ordinances, were not commonly referred to as a sacrament which is the religious ceremony.
The eye is the organ of sight. It is used in almost everything we do, from playing sport to reading. A normal and well functioning eye can focus objects and images, both near and far, perceive depth and adapt to changes in light.
The brain identifies what it sees in a series of steps. The brain makes a feature map of the eye breaking the visual field into sections. Information collected in a particular section of the visual field will always be sent to the
Vision is the most important sensory compared to other sensory modality therefore there is a wide range of research carried out on vision. Visual attention is defined as a term that portrays how individuals are able to change their view while attending to an image that is of a normal perspective due to the neurones in the cortex (Carasco, 2011). It is often described as a focal point which is situated with different locations in the region of space (Wright, 1998). Visual search requires detecting a specific target as quickly as possible. For example, trying to find your car in a large car park. By focusing our attention to the specific environment it improves our visual search of the target (Keane et al., 2015). The speed of a visual search
