Visual field

Development of the Visual System The visual system begins to mature in the early years of life and keeps adapting and changing till old age. Infants: Newborns have uncoordinated and poor saccadic eye movement. it isn't till 6 months that fixation is effective and the lens accommodation is close to adult levels. The rods are adult-like in newborns, but the cones are much thicker and can't absorb as much light. Only with maturity do cones become narrower and longer travelling to form fovea. All…

Kind of Learning Styles Do ESL Learners Prefer? Reid (1987) conducted survey on the learning style preferences of ESL learners. He analyzed the data based on various categories: age, mother language, TOEFL score, length of time in U.S., major fields, etc. Among them, we will discuss three background differences that affect learners’ styles. ESL vs Native (weak proficiency vs strong proficiency) The questionnaire suggests that ESL students often differ significantly in various ways from…

rebar using ant non-destructive method has been a challenging task, especially since they are embedded in prestressed concrete. Visual inspection is not efficient and useful method as it fails to locate rebar accurately. Magnetic sensor used for locating reinforcing steel present within in concrete work on the principle that the steel affects the alternating magnetic field. So this paper discusses development of system by utilizing maximum possible information from magnetic effect on rebar. …

the panel related how their majors/fields of interest influenced how they viewed the world around them. They also related the ways in which their fields of expertise could be used to promote and/or understand sustainability. In this essay I will attempt to relate how my own interests influence my world view and how my interests can be applied to sustainability. The PAC session was very thought provoking. At the PAC session the panel explained how their majors/fields of interest could be related…

Indeed, Dr. Mead has contributed a significant amount of her theories to anthropology, in order to enhance the field and allow the public to be included in the collaboration of anthropological work. Above is a picture of Dr. Mead and her newlywed husband at the time, on the right we have Dr. Bateson conducting fieldwork in New Guinea and on the left, Dr. Mead constructing fieldnotes. In this photo, both anthropologists are seen working together and observing the Papuan culture. Both couples…

the brain to receive input from ganglion cells is the lateral geniculate nucleus of the thalamus. From there the thalamus sends information to the primary visual cortex in the occipital lobe and area V1 sends information back to the thalamus. These two areas feed information back and forth. Area V1 also sends information to the secondary visual cortex (V1) which then relays that information to different areas of the brain. The ventral stream runs along the occipital cortex to the temporal…

Inside the church of San Marcello al Corso in Rome, there are two frescoes in a series by Francesco Salviati (1510-1563) whose unusual iconography caught my interest during a semester abroad. Though ostensibly depicting scenes from the life of the Virgin Mary, in both cases the titular narrative is rendered obscurely in the far background of the work while the foreground is dominated by the bodies of spectators who watch the scene. My senior thesis project, titled “Shaping Spectatorship in…

The current study sought to examine if visual perception plays a part in the effectiveness of motor skills when there is distributed practice. More importantly, what happens when one’s visual perception is distorted? Forty College of Wooster students participated in the test of motor skills and practice; half of the participants had their vision distorted using perception…

topic that is near and dear to my own career aspirations in optometry. As I have stated in several posts over the term, optometry (like dentistry or even public health) is a vastly underrated field of medicine. And with my long-term dream of getting into pediatric optometry and working with children with visual impairments, I saw an opportunity to bring the eyes and community health assessment into one project. Largely due to more accessible data sources and information, I found this project was…

The article illustrates findings describing separate visual pathways within the cortex that play different roles in interpreting visual information. These visual pathways include the ventral and dorsal streams which elicit visual perception and visual control of action, respectively. An important model for these findings was patient D.F., an individual afflicted with visual form agnosia, resulting in difficulties perceiving visual objects. In determining the origin of this patient's condition,…
