Sensory Perceptions
Human observers have fair accuracy within certain restricted domains. An example is a comparison of a flying ant and termites. The correct classification of each can repeatedly and accurately be made by many different observers with minimal training, thus making unaided vision and an accurate detector of termites. Despite elevation of human detectors by specialists in this field as the ultimate standard, the domains of accuracy, precision and resolution of the human senses, and even within those domains humans often do not provide the best results.
One may think that each sense consists in discrete and completely independent ways of processing information about the world. Also, there is the perception that the processing of signals from the eyes is completely separate from the processing of signals from the ears. Others still think that there are physically isolable systems in the brain corresponding to each sense. Looking at human physiological mechanisms pertaining to different senses, we find that they are not completely discrete (Macpherson, 2011). Research shows that there is interaction between sensation and audition referred to as sensory modalities. I believe human senses can be accurate because deliverables of senses feed into one cognitive system that comprises and governing beliefs, desires, thoughts, and other proportional attitudes. An example is that if one hears a scream and sees a Lion, it is obvious to come to one believe that there is both scream and Lion within the environment.
On the other hand, human senses are not without weaknesses. A Rhine (1997) note that there are weaknesses of human senses and gives an example of admiration of beauty. He illustrates that admiration of beauty is a symptom of human senses. If the senses were perfect, there would be no beauty. He believes that it is not someone’s nature but the weakness of the eyes of the onlookers that make one appear beautiful. Researchers have proved that from the numerous stimuli surrounding, human senses selects the stimulus that is of value from the many that are available.
The reasons for believing in
Roman Gonsalez Biology 101, Lab- Sec. 6 Dong Pei April 27, 2014 Sensory Processing & Perception Experiment one I came to believe that the closer that the object get, the greater the lens curvature. The larger the eye shape, the further the object must be to focus. The larger the eye, the greater the lens shape must be. I hypothesized that near sightedness develops when a person has a smaller eye shape and far sightedness develops when a person has a larger eye shape, like a football. Experiment…
Sensory Perceptions Ericka Lim-Spears Professor Ducksworth Philosophy 210 Critical Thinking 1/23/2015 Our senses are what connect us to the world we live in, without being able to hear, see, smell, touch, and taste, our lives would have little to no meaning as would our brains; they would be just as Aristotle and Locke called it a ‘Blank Slate’ (Kirby & Goodpaster, 2007). Often times our senses have the power to enlighten our minds or deceive them. Quite like how food brings our body…
stated “perception is the process of selection, organization, and interpretation of the sense-data into mental representation that can be use by the brain and the nerve system to provide content for thought” (p. 17). We can understand Perception as the process by that we interpret and receive information coming from an environment or ourselves. This information is received through the five senses: Sight (eyes), hearing (ears), taste (tongue), touch (skin) and smell (nose). Sensory perception is not…

vision. The main sensory organ of the visual system is the eye, which takes in the physical stimulus of light rays and transduces them into electrical and chemical signals that can be used by the brain to interpret physical images. The eye has three main layers: the sclera which includes the cornea; the choroid which includes the pupil, iris, and lens; and the retina which includes receptor cells called rods and cones. The human visual system is capable of complex color perception which is initiated…
Chapter 4 Critical & Creative Thinking Questions Tania Correia PSY103 January 26, 2015 Brian Hawkins Chapter 4 Critical & Creative Thinking Questions 1. Sensation and perception are closely linked. What is the central distinction between the two? The central distinction between sensation and perception would be the sensation begins with specialized receptor cells located in our sense organs (eyes, ears, nose, tongue, skin, and internal body tissues). When these sense organs detect stimulus (light…
independently from us; second, that we are directly aware of this world in sensory experience. Both quotes from the Enquiry, Section XII, Part 1 (AW 594b): “It seems evident that men are carried by a natural instinct or prepossession to repose faith in their senses, and that without any reasoning, or even almost before the use of reason, we always suppose an external universe which does not depend on our perception, but would exist though we and every sensible creature were absent or annihilated…
the structure of a neuron, and explain how neural impulses are generated. The neuron, a cell in the nervous system for information transfer, has various components in its structure. The dendrites are regions of information input and can end with sensory endings that respond to stimuli such as light or pressure. The soma is the cell body of the neuron and contains the nucleus and the cytoplasmic organelles of an average cell. If the soma is destroyed, the neuron dies, as it is the living part of…
Key Terms Chapter 3 Sensation: the process through which the sense pick up visual, auditory and other sensory stimuli and transmit them to the brain. Perception: the process by which the brain activity organizes and interprets sensory information. Absolute threshold: the minimum amount of sensory stimulation that can be detected 50% of the time. Difference threshold: a measure of the smallest increase or decrease in a physical stimulation that is required to produce a difference in sensation that…
individuals in varying professional fields there seems to “be an unbridgeable explanatory gap between what it is like to have a sensory experience and the neural correlates or physical mechanisms involved” (O’Regan et al. 2005). Some believe that to have a sense is to have a unique set of experiences associated with that sense (Keeley 2002). Others believe that the sensory modularity is related to things that in the world that affect behavior, regardless if an individual is consciously aware of the…
