The Perception Of A Infant s Visual System - 1717 Words

The phenomena of perception refer to the sensory processes that enables human beings to recognize and organized the information that is received from the environment. Such process allows individuals to perceive the world and objects. For such process to occur, theorists research visual perceptual patterns during the period of infancy. Research has found that there are differences between the way a newborn infant perceives the world in comparison to adults, as their visual system is not fully developed at such an early age. An infant’s visual system is heterochronus which disables them from seeing a complete view of the world, compared to adults. An individual’s visual system is constructed by different components. The eye and the brain perform different functions and go through different processes from the moment light is reflected from an object to actually obtaining visual recognition. Vision relies on the response of the nervous system to the light that has been reflected from an object, during this process many parts of the human eye are active. When a ray of light enters the pupil of the eye, the cornea refracts the lights and focuses the lights on the lens which focuses the light at the back of the eye in the retina. The retina then converts the light via optic nerves which enables the information to be processed in the brain, enabling visual recognition of the image which we see (Wade, 2001). This process is necessary, so individuals are able to comprehend what isShow MoreRelatedEssay on Infant Sensory Development1474 Words   |  6 PagesHave you ever wondered exactly how infants perceive the world around the m? If infants are exposed to certain foods in their prenatal development and are exposed to the food through their mother during breastfeeding after birth, will they remember that particular food later on in their life and prefer its taste to other foods? Is their sense of smell acute after birth or is it acquired over time? How do infants use the sense of touch to form relationships and learn about the fascinating world aroundRead MoreThe Development Of Facial Perception2429 Words   |  10 Pagesexamine three studies on the development of facial perception in infants. There is a large body of research already dedicated to this topic, maintaining this first year of life as an integral stage in perceptual development (Oakes Ellis, 2013). Facial perception is of particular is important because of its pervasive social implications (Bahrick, Lickliter, Castellanos, 2013). Greater understanding of perceptual ability may offer insights in to how infants interact with and learn abou t the social worldRead MoreThe Impact Of Technology On Our Understanding Of The Developing Brain1706 Words   |  7 Pagesembryonic progression show how the human brain and nervous system start to occur at three weeks from contraception, with the closing of the neural tube and By four weeks, major sections of the brain can be distinguished in a simple form, including the forebrain, midbrain, hindbrain divisions and optic vesicle, where the eye matures from.

Since Pringle-Morgan’s initial report, there have been many other explanations of dyslexia. This essay wil l attempt to evaluate phonological deficit hypothesis – which suggests that dyslexia is caused by a deficit in phonological processing –, with regard to competing theories such as the visual magnocellular deficit hypothesis, and the cerebellar deficit hypothesis. The phonological deficitRead MoreEarly Childhood Development Essay1836 Words   |  8 Pagesyoung, old, and infants look at things has been the subject of a number of studies for many years. These tendencies are referred to as visual preferences and in infants this study can be referred to as early visual perception. Though interest in the study of visual preferences has declined, significant progress has been made in this field. This study however has been very instrumental in helping scholars understand early childhood development issues. Among these issues is how visual preferences canRead MoreTheories And Evidence On Face Recognition2129 Words   |  9 Pagesconstruct their own perceptual worlds. Given that perception is always accurate, Gregory’s theory contradicts the unlikeliness that retinal images are unclear and incomplete. It also, explains, in a more efficient way, illusions than perception itself (Eysenck and Keane, 1995), a topic unfortunately not discussed in this essay.

The purpose of Kelly, et al.â€⠄¢s (2007) study was to look at the developmental origins of the ORE during the first months of life. Each infant was randomly assigned to one of four ethnic groups – African, Asian, Middle Eastern or Caucasian. The infants were then exposed to faces from these ethnicities and their novelty preference was measured. Three month olds infants showed a novelty preference for all ethnicities, while six month olds showed a noveltyRead MoreAttachments and Children with disabilities2166 Words   |  9 Pagesattachment also serves to keep the infant close to the mother, thus improving the child s chances of survival. We can learn that Attachment theory is focused on the relationships and bonds between people, particularly long-term relationships including those between a parent and child. The central theme of attachment theory is that primary caregivers who are available and responsive to an infant s needs allow the child to develop a sense of security. The infant knows that the care giver is dependableRead MoreSpiritual Formation1595 Words   |  7 PagesPiaget’s work on this stage, an infant orients himself or herself to objects in the world; by moving and reacting the infant learns what he is capable of as well as what the surrounding world is capable of.
