Accuracy or inaccuracy of sensory information
The sensory information in my opinion, can provide an accurate view of the world. It is because people’s lives revolve around senses and thought. There are five senses in living things, they include; sight, touch, taste, smell and hear. People’s thoughts are primarily an interaction with the sensory system. The accuracy of the sensory information, therefore, depends on a person’s thinking, fewer distractions in thoughts, sensory information are accurate. Enlisted are the reasons for believing in the accuracy of sensory information (Bueti, Bahrami & Walsh, 2008).
1. Touch. This sense majorly composed of skin allows one to detect dangerous materials. Hot and cold materials are touched and the touch sensor detects it and sends the information to the brain. The brain triggers a response to an act by removing the hand from the material.
2. Taste. The sensory organs in the tongue are vital in the accuracy of the sensory information.
It makes it possible for one to decide on the foods that can be eaten or a person’s preferences are based on the sensory organs of the tongue.
3. Sight: The organ responsible for sight, the eye, allows one to see a variety of things ranging from pleasant ones to the dangerous things. The sense of sight helps in the trigger off a response according to the information detected and sent to the brain. The response may be moving away or moving closer.
The above are the reasons for believing in the accuracy of the sensory information. They are a major key to the world wonders and allows one in the exploration of new things.

...here is a fire outbreak in the neighborhood, an adult person can smell the smoke and give meaning to the whole thing while a child will not be able to tell if there is a fire because the child does not have the memory of the smell of smoke. Hence can’t give meaning to it and act.

Sense Perception is a way of knowing in which a person can acquire knowledge using their five senses - taste, touch, sight, sound and smell. Sense perception is an important in our understanding of the world, and is a source of much of the pleasure in our lives. But, can we trust our senses to give us the truth? This may come out as an odd question to many because according to experience and history it is known that humans greatly rely on sense perception as a means of survival. However, like all ways of knowing, sense perception has its weakness; our senses can easily be deceived. In his TED Talk, “Are we in control of our decisions?” behavioral economist Dan Ariely uses examples and optical illusions to demonstrate the roles, strengths and limitations of sense perception as a way of knowing.
Firstly, there is various of sensing activities as in seeing and hearing as in a sense of understanding of what is seen and heard. Secondly the sense of feeling in numerous parts of the body from the head to the toes. The ability to recall past events, the sophisticated emotions and the thinking process. The cerebellum acts as a physiological microcomputer which intercepts various sensory and motor nerves to smooth out what would otherwise be jerky muscle motions. The medulla controls the elementary functions responsible for life, such as breathing, cardiac rate and kidney functions. The medulla contains numerous of timing mechanisms as well as other interconnections that control swallowing and salivations.
The unconscious mind can be explained in various ways and can take on various attributes. Carl Jung the author of “The Archetype and the Collective Unconscious,” defines unconsciousness as the first reactions and interactions a person endeavors. Several Physicists believe that the unconscious mind acts separately from our voluntary thinking. Scientist believes that understanding the unconscious mind is key to determining what type of archetype a person may have or develop. Experiments such as, reaction to stimuli, have lead cognitive psychiatrist to determine the strength of the unaware and involuntary mind. In addition, many social physicists have also believed that the unconscious mind is unaware of it actions and that the unconscious part of our brain can sometimes be focused on several signs that our conscious self can’t see.
In order to discuss sensory perceptions, we need a definition of the kinds of things that can be perceived, and a general acceptance of the terms used throughout the dialogue. Locke, in his work An Essay Concerning Human Understanding , describes an important distinction between the different qualities that we perceive in objects. He terms the two types of qualities perceived within objects as primary and secondary qualities. Primary qualities are defined as those which are inherent within the object (Locke gives examples of extension and form) , while secondary qualities are those created within the mind from primary qualities . Berkley uses the term “sensible quality” to express the same concept as Locke’s primary qualities: those qualities which can be observed directly by our senses . Once these ...

Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.
Perception is the process by which we grasp useful information about the external world through the senses. Armstrong argues in ‘Perception and Belief’ that perceptual experience is a disposition to form beliefs about the real world. The argument from illusion shows that perceptual knowledge is a misrepresentation of the world because external objects may have qualities they do not really possess. This is due to various experiences that are caused by hallucinations or by the influence of drugs. Given that reality can easily be altered by such cases, perception does not seem to represent a direct window onto the world. To overcome this problem, some philosophers like Russell postulated the sense datum theory as an object that stands in relation between the perceiver and an external object. Moreover, this view asserts that the perceiver is never in direct contact with reality but is in a continuous mental state that prevents him to see the world as it is. Hence, the perceiver is not deceived by the illusory cases because there is no objective world to be derived from. Armstrong rejects this theory by appeal to the indeterminacy principle and raises claims to support the reliability of perception as the acquisition of potential belief. On Armstrong’s view, the number of background inferences justifies the validity of perceptual beliefs with respect to providing knowledge of the external world. In ‘Sensation and Perception’, Dretske argues that perception and belief are not inextricably bound simply because belief requires a cognitive refined process of informational input while perception involves the casual flow of raw data not yet processed by the cognitive mechanisms. On Dretske’s view, a sui generis conception of perception tha...
With each of our senses (sight, smell, touch, taste, and hear), information is transmitted to the brain. Psychologists find it problematic to explain the processes in which the physical energy that is received by the sense organs can form the foundation of perceptual experience. Perception is not a direct mirroring of stimulus, but a compound messy pattern dependent on the simultaneous activity of neurons. Sensory inputs are somehow converted into perceptions of laptops, music, flowers, food, and cars; into sights, sounds, smells, taste ...
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
Lastly, behavior can also be determined by sensation and perception, the stages of processing the information gathered from the senses. Sensation and perception depicts the world for humans. Without them, humans would not be able to truly experience what is going on around them. The first step, sensation, is the gathering of the information from the outside would through the five senses: sight, hearing, taste, touch, and smell. The information is then organized and interpreted by the brain through
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
Their knowledge in the unconscious system is repressed and unavailable to consciousness without overcoming resistance (e.g., defense mechanisms). Thereby, the repression does not allow unconscious knowledge to be completely aware; rather, it is construed by means of concealing and compromise, but only interpretable through its derivatives dream and parapraxes that overcome resistance by means of disguise and compromise. Within the preconscious system, the contents could be accessible, although only a small portion at any given moment. Unconscious thought is characterized by primary process thinking that lacks negation or logical connections and favors the over-inclusions and 'just-as' relationships evident in condensed dream images and displacements. Freud asserted that primary process of thinking was phylogenetically, and continues to be ontogenetically, prior to secondary process or logical thought, acquired later in childhood and familiar to us in our waking life (1900, 1915a).
The Eye is the organ of sight. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he/she is really seeing is the light that the object reflects, or gives off.
