Sense data are the empirical mind-dependent ingredients of perception. They are the colours, sounds, smells, tastes, and textures out of which all experience is built. The idea of sense data is the cornerstone of the theory of Representative Realism, which states that immediate objects of awareness are not physical objects, but are sense data. Sense data are the subjective mind-dependent intermediaries that give us all of our knowledge of the external world through a veil of perception, representing the real world. The theory of Representative Realism is similar to Direct Realism, in that there is an objective mind independent physical world; however, we only ever perceive it vie a subjective mind-dependent intermediary (called sense data).
The idea of Sense Data is designed to circumvent many of the problems in Common Sense Realism. Sense Data successfully explains what illusions are, by placing the illusion in a personal veil of perception. For example, take a stick and submerge it half in water, so that it appears to be bent. This can be construed as a criticism of Direct Realism, because as we see the stick to be bent, but at the same time feel it not to be, we can assume one of our senses is misled, and so we do not perceive it directly. However, in Representative Realism, sense data explain this anomaly by placing the inconsistency in the subjective intermediary of Sense Data. The stick stays straight in the real world, but since all we can ever see is our Sense Data, and our Sense Data is subject to illusion or error, we perceive (wrongly) that the stick is bent.
Hallucinations are another criticism of Naïve Realism, because if we assume hallucinations to exist then they cause a major problem for this theory. Since everyt...

...finition is non-physical, so it contradicts itself. However, hallucinations and dreams can appear to us, in much the same way, have shape and form, and yet remain non-physical too, and yet they exist. This means that it is possible for sense data to exist, even though the idea contradicts itself, but it does not mean that sense data does exist for certain.
The claim that we perceive the world via sense data is a possibility. However, even though Sense Data explains why illusions, perceptual variation, hallucination, time lag occur, it is not necessary to explain these problems. A sophisticated Direct Realist can explain most of these problems just as easily. As both theories have problems, they can be favoured equal to one another; except Direct Realism is the most systematic, economic, practical, and simplest theory, and thus provides the best working hypothesis.
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.
... matter to forms of existence in the mind, for example to argue along with Berkeley (1710) that material events only exist in so far as they are perceived to exist (idealism). Idealism has its modern defenders, for example in some interpretations of the observer effect in quantum mechanics (the view that the Shrodinger wave equation only collapses into an actuality once an observation is made). In the macroworld it may also be true that the world as-perceived only exists if there are perceivers (Velmans 1990). However, as a general theory of the ontology of macroevents this position has its own well-known problems. It might be that the material world cannot have an appearance without perceivers, but it seems counterintuitive that its very existence is similarly vulnerable. Closing one's eyes, for example, does not seem to be enough to make unpleasant events go away.
A common definition of misperception theory describes it as “the gap between the world as it actually exists and the world as it exists in the mind of the perceiver” (Duelfer and Dyson, 2011). This definition is however, dependent on one crucial assumption, that there is both a single objective reality and multiple subjective realities. The key differe...
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 ...

Consciousness is something that is experienced on the daily basis, whether we are describing our awareness or perception of the physical world. David Chalmers provides his insight on consciousness by first identifying the easy problems presented by consciousness, then the hard problem that is puzzling and one that can’t be fully explained. The hard problem serves as crucial topic has sparked many philosophers to attempt to provide a solution for this problem. To Chalmers, the hard problem involves our experience. Ned Block responds to hard problem by providing his ideology of the epistemic gap that exists between phenomenal consciousness and access consciousness.
The world is full of stimuli that can attract our attention through various senses. This might include anything that can be seen, touched, tasted, smelled or heard. According to yuwachet siritham the process in which in we create our perceptions is done in three steps, which is. First we select, then secondly we sort, and finally the third one is we will interpret the data given by our environment.
Merleau-Ponty distinguishes three aspects of the psychological process; basic sensations, perception, and the associations of memory (Merleau-Ponty, 1994). Basic sensations receive raw information from the world and transduce them for our perceptual processes. Perception unifies the infinite amount of information about our environment, from our environment, into a meaningful structure. Perception is interpretive, but its presentation of the world is as distal and objective. There are three central features of perception for Merleau-Ponty. First, perception is synthesized independently by the body and not by the mind (consciousness).
The Webster dictionary determines perception to be knowledge by the senses and/or life that have an influence on people’s perception (Parker, 2010). The way people perceive things is based on their five senses. The sense of sight was the main sense used in the following experiment, as well as a person’s memory. Eyes tell people what they want to see and want to know. They tell you how to conceive a person and their behaviors as well as their reactions. It essentially judges the world around you. One is able to perceive how a person reacts to certain situations entirely by watching them. Perception applies to the interpretation of what we take in through our senses, in terms of optical illusions. Optical illusions happen because our brains are trying to define what it is that we envision and make sense of the world around us. If perception has no foundation in a person’s experience, a person may literally not perceive it. Perception is a method by which people set up and define their sensory impressions to give significance to their environment. Critical thinking is something we all do, because the regularity may range from person to person.
Realism claims that what we can review about our surrounding is established in the fact that they absolutely exist. What we believe about gathered information is what we think about the actual world. It states that there is an actual world that assimilates directly with what we think about it.
world of our senses as it interacts with the rational world of rules and limitations.
...he physical world, and believing that knowledge comes from what is seen and heard can confuse what reality is perceived as. Plato’s “The Allegory of the Cave” and Salvador Dali’s painting “The Persistence of Memory” show us how realities can be confusing and turn out to be something different. However, each and every one has a reality of his or her, to which they believe is true. If so, hopefully that reality is rational.

Sense perception is the process in which the faculties of sight, smell, hearing, taste, and touch, perceive an external stimulus of the knowledge about the outside world. Our senses act as an important source of knowledge about the world but instead of passively reflecting reality, it actively structures it. As such, understanding the world through sense perception is an active process that requires our brain to categorize and interpret what it is we are sensing. Yet, can the knowledge acquired through our senses be entirely trusted, relied and depended upon? There are certain factors that may interfere with how we perceive the world with our senses. Thus, sense perception, as a way of knowing, is selective and subjected to
An experience from everyday life that helps to work out perception and sensation is a football game. A ball could be kicked towards the goals. Two people will see the same ball going in the same direction at the same time yet one could say that the ball was a goal and the other could say that the ball went in through the goals for a point.
