Right Visual Field Essay

It is still not fully understood whether or not the action of certain tasks is actually dependant on both of the brain hemispheres, because they both appear to have control over some tasks. An example of this, is the left hemisphere which is said to be responsible for the analytic part of the tasks, such as reading and making calculations. Within many individuals, it is also the dominant centre of language

The left side sees and interprets the world in symbols and languages. However the right side interprets it in terms of space and shape.

The other test held was an auditory test. The test was done in two different ways. One way was finding the objects in a bag that were mentioned verbally and the other was identifying the item reached by touch. This test’s results were also supporting the previous researchers’ logical conclusion about the left hemisphere ability of speech. It confirmed the right hemisphere’s ability of comprehending language and its ability of expressing it in a nonverbal way. During the test, evidently, the right hemisphere had no trouble identifying the unknown objects by touch as the left hemisphere did. Moreover, some three- dimensional drawings of the slit-brain patients, who were all right handed, developed much better drawings using their left hands compared with their right hands.

As shown in the chart, the split brain has a low correlation than the intact brain, which has a higher correlation. This proves that a person with a split brain cannot process information to the left and right. Face recognition is in the right side of the brain while vocabulary and reasoning in the left side of the brain. When comparing face and reasoning it only gave a low correlation same with face and vocabulary. Vocabulary and reasoning is in the left hemisphere, therefore, being a bit more stronger than the rest of the results. In the intact brain reasoning, vocabulary, and face are being processed to the left and right showing that they are laterized.

In which exact placement of an object or word mattered if the image went to right brain or left brain. Tactical stimulation in which the participants were asked to feel the object but could not see it. And testing auditory was the hardest one they said because the sound enters through both of your ears so they are sent to both sides of your brain. But you can minimize to one side of hemisphere as Gazzaniga explained in his methods. After performing all this methods he revealed some fascinating findings about brain functions. With visual ability he said that both sides of your brain are equally skilled for visual perception. But when the lights were flashed on both sides of brain and the patients could only see the ones on the right because the center of speech is located on the left side of brain so in order to say that you saw the light the object have to be seen by the left side of your brain. With the tactile stimulation same thing was done but this time the object was placed in their hands and since the left hemisphere have verbal abilities it was easily identified the object that was placed in right hand but with left

The Direct-route pathway course inquiries, and the Inverse-route pathway course examinations utilize the use of a vocal policy or the modest recollection of the preceding practice are no longer successful. The Giusberti, et al, (2010) study has adopted a viewpoint that has never been practiced before, and they are required to represent the psychological atmosphere. It recommends that the frequency of images hemineglect disturbs the capability to steer when the subject has to use a mental diagram of the situation (Giusberti, et al, 2010). It is still being discussed whether the discrepancy detected in subjects is owed to struggles in constructing a psychological chart, recollecting it from recollection, or utilizing it throughout direction finding (Giusberti, et al, 2010). Appraising hemispheric engrossment in graphic psychological imaginings, and the findings showed that right and left intellectually impaired subjects with no sign of representative hemineglect completed faultlessly in the visualizations tasks (Giusberti, et al, 2010). Useful neuroimaging experiments recorded that both hemispheres are complicated in psychological imaginings treatment (Giusberti, et al,

The effects of two treatments for word retrieval impairments in aphasic individuals. With the use of errorless naming treatment (ENT) and gestural facilitation of naming (GES). The effects of the two treatments that were used for a daily picture naming/gesture production probe measure and in standardized aphasia tests and communication rating scales were administered across phases of treatment.

Mead & Hampson (1996) developed a study involving the divided visual field paradigm and a phonological rhyme/non-rhyme task to test the speed and accurateness of either side of the brain. This study was used to investigate functional asymmetry between the left and right hemispheres in phonological processing. The research was taken out equally on 15 male and 15 females London Metropolitan University students ranging from ages 18 – 35 years old. They were all specifically chosen to be right–handed and had English as their first language thus providing a fair experiment to see whether our left hemisphere (left side of the brain) or the right hemisphere is faster and more accurate. In conclusion using the mean and standard

For many decades people have been considered to be either right or left side dominant in regards to brain function which came with defined roles such as “creative” or “analytical”. This thinking tends to be over-simplified as most people use their entire brains daily (Jensen, 2010). On the other hand people do use different parts of their brain for different tasks according to how they perceive those tasks.

When I arrived at L.N.’s home, they were playing in front of their home while her father worked on the garage. L.N. was playing with her older sister, her sister is two and two months older than her. Both girls were blowing bubbles while the other attempted to grab them. At this moment, I realized that L.N. was left-handed as I saw her handling the “bubble-maker” on her hand and attempted to grab the bubbles with her left hand. This is an example of lateralization; her right side of the brain is the dominant region.

In 1982 Ungerleider and Mishkin proposed the existence of a dorsal stream that processed special features, such as location in the field of view , and a ventral stream that processed visual features, such as the color or texture of the actual object. Through this model, the idea of “where” vs. “what” was formed. They tested this idea through an experiment where monkeys had been trained for two specific tasks, one that used the “where” and one that used the “what” aspect of vision. The experimenters then created brain lesions in the parietal cortex of some of the monkeys to test how it affected “where” and brain lesions in the inferotemporal cortex in the other monkeys to test how it affected “when.” “The results showed that monkeys with damage

Cross hand-eye dominance has been proven to create problems for certain people that don’t prefer a certain side of their body and can even result in problems with language, and learning along with the increase in the prevalence of ADHD. In the brain of a person with cross dominance, information normally processed on both left and right sides of the brain is forced to travel back and forth between both hemispheres. Since the process of receiving the information takes longer than normal, often times it results in developmental delays and later on could develop into a learning disability. The cross dominance creates a type of confusion in the brain and results in the disorganization of information, similar to a filing cabinet. If it is alphabetized

In general, the brain is thought to be lateralized with the two hemispheres having control of the opposite side of the body and their own functionalities. In this case, the left hemisphere dominates in language and verbal capabilities controlling the right side of the body including the right visual field. Using this fact and the difference in visual fields, subjects were asked to focus on a flashing screen with a pulsating plus sign. Vertically oriented words would flash on either the left or right side of the plus sign in order to isolate individual hemispheres. The time to correctly identify the words was recorded and compared between the left and right visual fields as well as between males and females. In this case, there was a significant difference between visual fields with the right side being significantly faster at processing words. In addition, males showed greater differences between visual fields when compared to females. These findings suggest that the right hemisphere is more selective in word processing and that males are more lateralized than females.

Left and right sided brain learners learn through different pathways of input to comprehend. When considering emotions both sides of the brain are responsible for emotions; the right side is known for negative emotions and the left side is known for happy emotions. The left side of the brain is responsible for language and math learning. As a left sided brain learner a person is a logical detail learner that focuses on facts and rules of language. The left sided brain learner is also focused on math and science in relation to pattern perception. These individuals are

Phenomena like Pseudoneglect, Hemispatial neglect, and Inattentional blindness incites psychologists because they want to know why such cognitive deficits occur. These types of phenomena all stems from attention. The ability to be completely normal, but make leftward errors in line bisection because the left side of space tends to be favored; the ability to only attend to one side of one’s body and completely ignore the other; or the fact that we miss activities that occur right in front us, all contribute to cognitive research that interest researchers. Studies about attention are separated into two groups, spatial attention and temporal attention. Spatial attention simply means attention in space and temporal attention measures attention over time. This study concentrates on temporal attention and how it relates to learning.
