Introduction
It is evident that the capacity to visually recognize things or objects is far much superior in comparison to the recognition by the use of the sense of touch (Saal, Vijayakumar & Johansson, 2009). Moreover, in comparison the ability of a human being to recognize objects visually is considered to be much accurate as well as faster than the case of tactile recognition. However, in the case of human beings visual recognition requires some brief palpations on an object in order to properly mark the identify of that object (Tonkonogiĭ & Puente, 2009). The sense of touch for any human being or species provides immense data regarding the surrounding world. Tactile recognition or the sense of touch is usually the first to develop and lasts even after the two other cognition senses fade away; visual and auditory recognition (Warren, Santello & Tillery, 2011). Though, Verrillo (1966) suggest this may due to the fact that ones are more aware the loss of visual and auditory senses as they are more salient and the deterioration of tactile senses are less noticeable. The sense of touch is considered to be an informative, active as well as perceptual system in any species. However, it is essential to point that the aspect and practice of tactile recognition plays a frequent role in an individual’s daily life. Therefore, it can be stated that tactile recognition is important and central to a human being as substantial amount of the human activities relate to touch. For instance, in the case of preparing this essay, a sense of touch is present in either the case of typing the keys on a computer or touching the pen when writing on a note pad. The need to identify the objects that one wants to use at a particular time plays a pivotal...

...reduction in the frequency if exploratory procedures and the impairments related to the haptic object recognition. Although significant progress has been made in the field of tactile agnosia as well as tactile cognition, there is still need for additional research studies particularly with the focus to understanding the autobiographic forms of tactile cognition. In the case of a patient recovering from stroke, usually involves the reorganization of key functions and structures after the lesion. This is because an acute stroke usually leads to metabolic and physiological reactions that are time independent. This enables changes both in the functions as well as organization in the cortical regions. It is evident from recent studies have thrown light to the level of reorganization and changes that happen after a stroke and how these changes relate to tactile agnosia.
The symptoms of a right-hemisphere stroke are very much similar like the symptoms Mr. Fix-it is experiencing. For example, both suggest that functions on the left side of the body are completely neglected; therefore, the left visual section of the body does not respond effectively to stimuli due to the neglect. Damage to the right occipital lobe is very likely. The patient may have experienced some damage to areas 18 and 19 of the occipital lobe. “Damage to these association areas resulted in the patient’s failure to recognize items even when they have been seen before”, such as Mr. Fix-it’s deficiency to recognize geometric shapes (Carlson, 2010). Moreover, the patient could have also experience damage in the frontal lobe, specifically on area 8, in which it could have r...
Anne Louise Oaklander then proceeds to discuss touch. She explains that senses have evolved specialized organs to process senses that were already discussed in this forum. Touch however, as Oaklander explains, can be perceived all throughout the body- something she likes to refer to as “somatosensation.” Oaklander defines somatosensation as: “A product of a number of different kind of sensory processes all chiming in to give you a perception.” All these sensory processes are somehow connected with processes in the brain.
Hemineglect also known as unilateral spatial neglect, hemispatial neglect, hemi-inattention, hemisensory, parietal neglect or spatial neglect (Kerkhoff, 2000), is a condition in which patients are unable to attend and respond to the contralesional side of space (Dijkerman, Webling, ter Wal, Groet, & van Zandvoort, 2003). Hemineglect is characterized by the lack of spatial awareness, most commonly on the left hemispace (Parton & Malhotra & Husain, 2004). The most common form of hemineglect, is that of patients who have right hemisphere lesions commonly found to damage the ‘where’ pathway, most commonly after a stroke. These kinds of patients tend to neglect the left hand side of space (Driver & Mattingley, 1998). Although it is not restricted to right hemispheric lesions in the ‘where visual pathway’, it is more predominant and tends to be harder to rehabilitate back to full recovery (Parton; Malhotra; Husain, 2004). Hemineglect does not just present itself visually, but also through other senses such as motor neglect, auditory neglect, representational neglect and also personal neglect (Plummer, Morris, & Dunai, 2003). Hemineglect is not a result of loss of sensory disorder. It is not uncommon to receive left hemisphere lesions or trauma and gain hemineglect. It does seem however that it is easier to treat and rehabilitate patients to a full recovery if this damage has occurred, compared to right hemisphere damage.
Smart – “when I say that a sensation is a brain process, I am using “is” in the sense of strict identity” . The strict identity is of great importance, as if it were to be any weaker, to suggest only a causation or a correlation between sensations and brain processes it would leave space for sensations to be explained as something “over and above” brain processes, thus providing no
Our five senses –sight, hearing, smell, taste and touch help the ways in which we perceive the world around us. And while they seem to work independently at time they can effect each other and the way we comprehend something. Seeing something pretty, touching something soft, eating something cold and smelling something rotten are the sense we use to connect with the world around us and will all effect how we move forward in that situation. When you look at the top picture say the color of the word not the word itself. It is harder than it seems and takes a little practice to do it efficiently. It is because we see the spelling we were taught not the color it was written in. It is hard to process it the other way, but not impossible. Take the bottom picture for another example is this a
This paper aims to endorse physicalism over dualism by means of Smart’s concept of identity theory. Smart’s article Sensations and the Brain provides a strong argument for identity theory and accounts for many of it primary objections. Here I plan to first discuss the main arguments for physicalism over dualism, then more specific arguments for identity theory, and finish with further criticisms of identity theory.
If brain cells die or are damaged because of a stroke, symptoms of that damage start to show in the parts of the body controlled by those brain cells.
We are taught, at a young age, how important our five senses are. These senses are essential to survival and are the necessary feedback for our existence. The question becomes though, what are really our senses? Touch, smell, sight, hearing, taste are the ones engrained into us, but there’s more to it, we can sense temperature, acceleration, movement, and even intangible things such as hostility, fear, or even someone or something’s gaze. While questioning why these are important and vital senses it raises a question of what is not included in the taught set of senses. Are senses real or are they a figment of our imagination created to give us a virtual reality? When people have senses that are better than others does that make our senses reliable? Rene Descartes ran into these questions himself in his Meditations on First. He distorted the perspective of senses by relabeling the concept of dreams, the beliefs of a powerful entity, and the mind itself. Descartes decides to call all individual opinions into doubt,

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.
Along with vision, hearing is one of the most important senses that humans have. We use it to communicate, learn, and stay aware of our environment. In fact, hearing is the only sense that never stops receiving sensory input. While all of our other senses become drastically less sensitive when we are sleeping, our brain still processes auditory information to awaken us the second something is wrong. Although this may have been more practically used before people slept safely in homes, it’s still useful for hearing a fire alarm or our alarm clock in the morning. We are able to hear by processing sound waves. This energy travels through the delicate structures in our ears to be transformed into neural activity so that we can perceive the sensory information we receive (Myers, 2010).
First, one must have the five senses; taste, smell, hear, see, and feel. Yes, these are physical aspects, however, these senses are what any human needs to be, human. For example, the human body needs to be able to taste. It must ingest food, and the food must appeal to a decent taste. A human must also be able to smell, so one may smell a poisonous gas, delicious food, or any other stench that may linger in the air. To be able to hear, enables the human to hear danger or a noise that appeals to them. When seeing, danger is also noted as well as the care of others. When one feels, the object that is being felt may make the person feel comfortable. Not only the sense of touching, but feelings.
