Human beings have five senses which are responsible for controlling inputs from the outside environment. Primary senses have unique sensory input, mechanisms,s and a structure underlying their function (Allport, 1987, p. 395). The reasons share a common role of picking sensory information from external sources and then processing it into the perceptual experience. For instant in vision, the process happens in the eye where photoreceptors on the retina are activated by light, which helps in the processing an effect on the visual cortex hence bringing up the aspect of sight (Mozer & Vecera, 2005, p. 135).
Other experiences, such as touch, temperature, and pain, result from mechanoreceptors, thermoreceptors, and nociceptors on the skin. They are responsible for information sent to the somatosensory cortex. The sense of smell results from odorant receptors located in the nose, which detects structures and gas molecules within the surrounding, and hence it carries out the process of identifying, discriminating, and evaluating odors qualities (Mozer & Vecera, 2005, p. 133).
The research paper is a study of visual mechanisms as applied to attend. The paper has a brief introduction, a detailed literature review, and a conclusion of based on the gathered literature. There are several visual selective attention has been studied by which, including intermodality attention, visual-spatial attention, intermediary attention as well as visual features attention (Mozer & Vecera, 2005, p. 134).
Key Terms: Visual attention, nervous system, stimuli, gaze Taste is also another sense which involves the identification of solid or liquid molecules through tongue receptors which enable the gustatory cortex to process taste quality information (Sherrington, 2000). Scientists have greatly tried to utilize a variety of psychological, neuroimaging techniques, and behavioral to try and explain how the organization of these inputs is done in the brain and also how the coding brings about the aspect of perception experience (Desimone & Duncan, 1995). However, most of the research has touched on the area of visual and auditory perception.
Other theories have tried to explain how attention is achieved, where one is supposed to concentrate on a particular object while ignoring the other. In this paper am going to discuss different research, theories, and biopsychology that affect attention. Visual-spatial attention has mainly addressed the aspect of gaze (Schroeder, Mehta & Foxe, 2001, p. 684). Studies done using both human beings and monkeys have shown that if one directly gazes in a particular direction or an object, the aspect of attention will be determined by the stimuli from the attended location. This can be shown by comparing the response that one produces as a result of the stimuli (Neumann, 1984).
It means that the response will depend on what a person has concentrated on or pay his attention to. What an individual has concentrated on will be shown...
