Extract of sample "Sensation and Perception"

Sensation and Perception The ears, eyes, tongue, nose and the skin sense the world around a person; in some cases they also process the incoming information. However, in many cases, individuals do not feel sensations – but get experiences of the perceptual outcomes (May 2). Sensations refer to the packages formulated by the brain, from the incoming data received from the senses, so that the individual can get a certain experience. This is the case, when a person looks at the face of a friend, noting that they do not see a mix of shapes and colors, but they see an image of the friend (May 2).
The interpretation of the environment by the perceptual system
The meaning-development process of a person entails the automatic functions of the wide array of perceptual functionalities. Among these is sensory interaction, which refers to the cooperative work of the varied senses and sensory functions to formulate an experience for the individual (Crowe 134). One application of sensory interaction is the collection of processes involved, when the interpreted sensations of smell, taste and texture are integrated to formulate (perceive) the experience of flavor, which is experienced for different foods and drinks. Sensory interaction is also actualized, during the experience of watching a movie, where the individual combines the sensory data collected by the ears, the eyes and the sensations triggered in their mind and body, which leads to an interpretation of the ways in which the music and the images work in harmony (Crowe 134).
Selective attention refers to an individual’s ability to focus on some incoming sensory signals, while at the same time closing out on others (Golstein 351). Selective attention allows a person watching a football match, to avoid taking in the visual data of the actions of the audience outside the field, irrespective of the fact that the different messages are coming in simultaneously (Golstein 351). In the case of selective attention, sensation, which is the process through which the human sensory systems and the nervous system receives and presents stimulus from incoming data channels conscious awareness to the data, which is filtered in. As a result, the perception, which is the organization and interpretation of sensory information, focuses on the data which is filtered in, therefore making meaning of events and objects for the individual to remain consciously aware of, and not aware of other experiences (Golstein 351).
Sensory adaptation refers to the case where the sensory receptors of an individual vary their sensitivity to the stimulus being received (Nevid 94). The phenomenon takes place for all senses, except in the cases of the sense of pain, in some cases. In orchestrating this response, the sensation of signals from the environment is varied – allowing for more or less intense reception of signals – and also the representation of the stimulus energies to be perceived (Nevid 94). In complementing the changes in sensation, the perception organizes the varied levels of stimulus energies and interprets the sensory information, which allows the individual to develop meaning of the events or the objects. One example of such a case is dark adaptation, where the sensation of darkness is lessened through the increment of the size of the pupil and the sensitivity of color receptors (Nevid 94). The more light allowed into the eye allows for the stimulation of the retina, and the increment of light sensitivity enables the individual to see in relatively dark surroundings.
During the orchestration of perceptual constancy, sense organs take in information through the process of sensations, and the stimuli resulting from the sensation are interpreted as signals, which the individual’s brain is able to process (Golstein 455). The interpretation of the information is mainly the work of the perception. Through the working of the sensation of an object and the perception, the individual is able to detect data about the visual object, and interpret that it is the same one, despite the fact that it may produce different images or sizes on the retina (Golstein 455). For example, when the individual sees a picture of his car in a picture, the perception interprets its color, model and shape – allowing him to recognize it – despite the fact that it will be smaller than it appears in real-life.

...? Sensation and perception: What can phantom limb pain teach us about the human brain? due: Introduction A phantom limb is the impression that a surgically removed or missing limb is connected to the body and coordinates with the other body organs. This sensation is experienced by approximately 60-80% of all amputees with the majority experiencing phantom pain. Other than limbs, phantom pains and other sensations also occur for other amputated parts of the body. These may include the eyes, breasts, teeth etc. The amputees have reported the missing limbs to feel shorter than normal and out of place or distorted. Phantom limb pains can be intensified by anxiety, stress and weather changes. The pains are normally intermittent... this led...

...Sensation and Perception Homework 1 The design of a visual system Before explaining the visual design for the particular species, it is better todepict here how actually the living beings see objects. All the living beings differently see objects according to their body shape and the surrounding environment. However, they have some components common which help them to see. These are eye, visual pathways and the visual centers of the brain. The function of eyes is to capture light and convert it into the neural messages. The visual pathways modify and transmit these messages from the eye to the brain where the messages are interpreted by the brain and thus the living being "see" the object. For this process to complete the function... of the...

...Sensation and perception: stereoscopic vision Sensation and perception: stereoscopic vision The story about Dr. Barry Sue is one amazing but the rather mysterious story to any normal human being as I, who have not experienced stereoscopic vision, unless with the aid of the space age 3D technology present on earth. I find it rather exiting in that an individual can develop wonderful skills left by creation and nature for us to explore. No one ever knew that someone like Dr. Barry would achieve such a vision based on her already limited vision capabilities. Living in such a life as Dr. Sue would be interesting but rather challenging both socially and mentally. Telling one’s...

Sensation and Perception

...). Perception in motor control is of great essence as it enables important information about the surrounding objects, environments and bodies to be used in executing actions and movements. There is an ongoing debate in the field of developmental neuroscience about the importance of activity-dependent processes (Dotson, 1997). There is a relatively delayed rate of human development of the brain as compared with the rest of the animals. The constant interaction of the infant with the environment helps sculpt various connections within the cortex which eventually results in a highly specialized adult brain (Gilman, 2002). The available theory suggests that human infants are usually born with the ability to sense a number of stimuli... , and as...

...Brain’s Perception of Language & Effects of Boca’s Aphasia Brain’s Perception of Language & Effects of Boca’s Aphasia The brain can be considered as the central point of processing sound into language. Therefore, the process of the brain perceiving language starts with the sound signal levels then the audition processing. This leads to the production of the initial auditory signals that are further processed into speech sounds. The processed speech sound often leads to further processing of extract phonetics and acoustic cues information. The developed speech information can now be used to process high level language (Honjo, 1999). Therefore, the brain must receive sound signals to process them into...
