In our daily lives, we have come to recognize motion in regards to ourselves and other stationary objects around ourselves. We concluded that of an object that maintains it position with respect to the immobile objects, is at rest. We also determined that all objects moving, along with the earth without changing its positions on earth surface is considered stationary objects in the earth’s frame of reference. So theoretically, “all bodies not changing position with respect to a specific observer is stationary in the frame of reference attached with the observer.”(Singhil) Hermann von Helmholtz stated, “A moving body whose motion was not retarded by any resisting force would continue to move to all eternity.”(Brainy) Helmholtz means that every single thing on earth is always constantly moving. What is motion; it is a state which indicates change of position. Motion of a body refers to the time given in a frame of reference. A frame of a reference is a method to describe space from the perception of an observer. In other words, it is a system of measurement for locating positions of the bodies in space with reverence to a viewer. These terms “reference” and “observer” are used to explain and describe motion. A frame of reference is a mathematical construct that specifies the location of a point of an object in space. The frame of reference is a coordinate system. The most common coordinate system is the Cartesian system, it comprises of three perpendicular axes. Observation of motion is considered a human endeavor, but the motion of an object would be considered both human and non-human things, such as clouds, rivers, moon, and mountains. There are also three different types of motions real time motion, two dimensional motions, and linear motion. Real time motion is the most complex motion because the bodies are subjected to many forces. This motion doesn’t happen in a straight line or plane, such as a bird flying in three dimensions. An example for two dimensional motion is “a ball thrown at an angle with horizon is described in terms of two coordinates x and y.”(Singhil) One dimensional motion is described using one of the three coordinates, while the other two remain constant during the motion. How do we distinguish motion? An object or body in motion cannot perceive its own motion. For example, we live on earth in an immobile state where we don’t realize that the earth is moving a high speed around the sun. The earth is moving at about 30 km/s, a speed that is faster than the fastest airplane that mankind has developed. As observers, we manly ignore or are unaware of the speed of an aircraft or automobile that we would be traveling in. To an observer the passengers and parts of the aircraft are all moving at the same speed, which gives the impression that the passengers are sitting in a stationary state. Remarkably, the motion of a body and its measurement is found to be influenced by the state of motion of the observer itself and hence by the state of motion of the attached frame of reference. For example, “Two observers in the same state of motion, such as two persons standing on the platform, perceive the motion of a passing train in exactly same manner. On the other hand, the passenger in a speeding train finds that the other train crossing it on the parallel track in opposite direction has the combined speed of the two trains.”(Singhil) Thus, explaining the interaction between the motions of both the object and observer. In conclusion, we have to perceive the study of motion through a new scientific approach. What we have learned is that the scientific meaning of motion has many interpretations from the point of view of earth or an observer. Robert Collier stated that “all motion is cyclic. It circulates to the limits of its possibilities and then returns to its starting point.”( Brainy) Motion is happening all around us all we have to do is open our eyes to view it all.

...at any time during a gallop. Muybridge sets up a series of cameras along the horses path; which are set to trigger in sequence as the horse runs by. The mechanism that was used for this to occur is called a Phenakistoscop. After successfully taking the pictures of the horse in motion he continued to take picture of other animals and the such. He eventually published the book "Animal Locomotion" containing these images. His work was great help not only artistically but scientifically to the world. Now although animation is possible to produce what good would it be without someone to watch and who better than a human. Mainly because of how we see and perceive motion. An example would be a slow moving hand we can see crisp and clear and tell that its moving and where it is at all times. Now let us say that hand is moving really fast now as if someone is throwing a punch. It is not super clear but we are still able to block, dodge, or parry that punch. We are able to do that because of the motion blue affect which allows us to see high rates of movement is fluid actions. If we were to see each frame of movement it would seem choppy to us, so instead we have a blurred object that we are still able to perceive and react to. This...

...To all the things that we do not perceive but are there for us to see are call Environmental Stimulus and we call Attended Stimulus to those things in our environment that catch our attention, the things to which we pay attention. One’s a perception happens we recognize the object or situation another proses began to transform this information into action according to our knowledge. This one is always influence by our knowledge, colors and interest. This information brought to a situation can be something learned time ago or knowledge gained by events previews to the present event. In this subject there are some tools that help us perceive they are call fundamental quintiles. They work thru our knowledge and help us recognize position, mass, or displacement. Example on a play perception of the audience is different than what goes on behind the séance. Behind the séance there are so many thinks going on that we are not aware of. On the other hand for someone when is on the audience and has work as on a play would have a different perception then everyone else, he might see the nerviest from the actors, or would see details that no one else can see. This is because our knowledge changes the perception of what we see or hear. In this example we see that the Environment stimulus is all thinks that we can potentially perceive like the trees or flowers. Aon the other hand the attended stimuli would be the bear. The process is constantly repeated all the time, our body gas sensors...

...Annotated Bibliography PSY/ 345 Annotated Bibliography Cavanagh, P. (1992). Attention-based motion perception. Science, 1563-1565. Retrieved August 09, 2015, from http://www.jstor.org.contentproxy.phoenix.edu/stable/2879947?pq-origsite=summon&seq=1#page_scan_tab_contents Attention often plays a crucial role in motion perception. For example, when a stimulus contains two components moving in opposite directions, attentive tracking of either one can reveal its motion independently of the other. Many neurons in primary visual cortex are sensitive to the direction of motion and attention might act by selecting one or the other of these low-level motion responses. Experiments have demonstrated that the perception of motion during attentive tracking can arise independently of low-level motion responses and may be derived from the internal signals that move the focus of attention. What the studies found in this experiment is tracking of spatial features depends on identifying form boundaries, and it appears that the form signal from luminance is especially susceptible to masking by color. This might be expected because any object traveling through a shadowed environment will have many luminance boundaries drifting across it that are unrelated to the object and need to be discounted, whereas color boundaries are more reliably tied to object borders Cues for depth perception.

Terp. No wonder; I should rather be surprised at hearing anything else of him. But why did he go on, instead of stopping at Megara? Euc. He wanted to get home: although I entreated and advised him to remain he would not listen to me; so I set him on his way, and turned back, and then I remembered what Socrates had said of him, and thought how remarkably this, like all his predictions, had been fulfilled. I believe that he had seen him a little before his own death, when Theaetetus was a youth, and he had a memorable conversation with him, which he repeated to me when I came to Athens; he was full of admiration of his genius, and said that he would most certainly be a great man, if he lived.

...Perception & Psychophysics 2004, 66 (6), 926-942 Effects of grouping and attention on the perception of causality HOON CHOI and BRIAN J. SCHOLL Yale University, New Haven, Connecticut Beyond perceiving patterns of motion in simple dynamic displays, we can also perceive higher level properties, such as causality, as when we see one object collide with another object. Although causality is a seemingly high-level property, its perception—like the perception of faces or speech—often appears to be automatic, irresistible, and driven by highly constrained and stimulus-driven rules. Here, in an exploration of such rules, we demonstrate that perceptual grouping and attention can influence the both perception of causality in ambiguous displays. We first report several types of grouping effects, based on connectedness, proximity, and common motion. We further suggest that such grouping effects are mediated by the allocation of attention, and we directly demonstrate that causal perception can be strengthened or attenuated on the basis of where observers are attending, independent of fixation. Like Michotte, we find that the perception of causality is mediated by strict visual rules. Beyond Michotte, we find that these rules operate not only over discrete objects, but also over perceptual groups, constrained by the allocation of attention. Long traditions in both philosophy and psychology have concerned themselves with the origin of our notions of cause and effect, precisely...

Information

...Through the perceptual process, we gain information about properties and elements of the environment that are critical to our survival.  A number of factors operate to shape and sometimes distort perception These factors can reside:  i) In the perceiver  ii) In the Object or target being perceived or  iii) In the context of the situation in which the perception is made.  1. Characteristics of the Perceiver: Several characteristics of the perceiver can affect perception. When an individual looks at a target and attempts to interpret what he or she stands for, that interpretation is heavily influenced by personal characteristics of the individual perceiver. The major characteristics of the perceiver influencing perception are:  a) Attitudes: The perciver's attitudes affect perception. For example, Mr. X is interviewing candidates for a very important position in his organization - a position that requires negotiating contracts with suppliers, most of whom are male. Mr. X may feel that women are not capable of holding their own in tough negotiations. This attitude with doubtless affect his perceptions of the female candidates he interviews.  b) Moods: Moods can have a strong influence on the way we perceive someone. We think differently when we are happy than we do when we are depressed. In addition, we remember information that is consistent with our mood state better than information that is inconsistent with our mood state. When in a positive mood, we form more positive impressions...

...has resolved to sweep away all he thinks he knows and to start again from the foundations, building up his knowledge once more on more certain grounds. Rather than doubt every one of his opinions individually, he reasons that he might cast them all into doubt if he can doubt the foundations and basic principles upon which his opinions are founded. What he learned is through senses. But they can be deceived. Use dream example. Convinced objects in dream are real. Dream images are drawn from waking experience. Meditator concludes, though he can doubt composite things, he cannot doubt the simple and universal parts from which they are constructed like shape, quantity, size, time, etc. While we can doubt studies based on composite things, like medicine, astronomy, or physics, he concludes that we cannot doubt studies based on simple things, like arithmetic and geometry. Simple things can be doubted. God would not deceive. It is an evil demon’s work (Meditation 2- cogito ergo sum and sum res cogitans)He recalls Archimedes' famous saying that he could shift the entire earth given one immovable point: similarly, he hopes to achieve great things if he can be certain of just one thing. Recalling the previous meditation, he supposes that what he sees does not exist, that his memory is faulty, that he has no senses and no body, that extension, movement and place are mistaken notions. Perhaps, he remarks, the only certain thing remaining is that there is no certainty. Then, he wonders,...

Leadership and Organizational Behavior

... This case study involves the importance of perceptions and how it effect attributions in the business world. We will use Joe Salatino, President of Great Northern American, as an example of how businesses can be successful when their customers are their top priority and employees learn how to understand their customer needs to improve sales. There are three learning theories operational conditioning, social learning and learning. We will discuss how one of these theories would be appropriate for Mr. Salatino’s business and how that theory could improve his employee’s performance. The last item is how self-efficacy is used to ensure the best candidate is hired for the company who can be successful. Mr. Salatino has a successful 35 year business. The reason is based on paying his employees bonuses and commissions in relation to their sales. The one thing Mr. Salatino’s employees need to understand is the importance of how people form perceptions and make attributions. So, what is perception? Perception is “the process, by which the individual selects, organizes, interprets, and responds to information” (Organization Behavior, p. 104). However, one perceives something to be is true to them even though their perception could be completely wrong.

Perceptual Filters

...Dillon Marchello 4/25/16 PL101 Taking Control of Perception Filters Throughout life, people go through their day to day schedules seeing and perceiving just about every experience in a “certain light.” A light in which shade is brighter, darker or just “blah” depending on that person’s overall self-awareness, mood or attitude. An individual’s mood or “filter,” as I like to call it, acts as a pair of glasses that can literally transform all of your surroundings and how you experience them. Your mood and emotions (for the most part) determine the “type” of glasses you are perceiving your reality through. If an individual is angry, their “angry glasses” will be slipped on, seemingly subconsciously, and the “energy” around them immediately loses its value and becomes diminished in a sense. Think about it, have you ever woken up, and as you were getting out of bed you stubbed your toe, and the rest of your day seemed to be more aggravating than usual? Maybe your commute to work seemed slower and more agonizing, or when you finally got to work your boss asked you to pick up an extra task because someone else didn’t show up that day. In other words, everything seemed more tedious to the point where you are just “not in the mood.” It is not that, all of the sudden, on that specific day the world changed its perception and attitude towards you, but because you changed your perception and attitude towards the world. The most dangerous part about these perception filters is that it...

...Name Professor Course Date Metaphysics METAPHYSICS The word metaphysics is derived from Greek words; Meta meaning beyond or after while physicia means physical which refers to the works on matter by Aristotle in antiquity (Statile, et al. 2006). Therefore, it is literally after physics. Metaphysics is a branch of philosophy that is concerned with the understanding and the explanation of the fundamentals of Nature of being and the world (Statile, et al. 2006). It seeks to investigate the principles of reality; state of things as they exist and whether or not they are observable or comprehensible. Aristoterian hylomorphism Aristotelian hylomorphism is a philosophical theory that was developed by Aristotle, which analyzes substances into matter and form. Aristotle theory seeks to understand the inherent quality in matter that a substance conceives as forms (Statile, et al. 2006). Aristotle’s hylomorphism theory, therefore, seeks to relate matter and form, soul and body and substantial form, accidental form and prime matter. This theory has given rise to many debates by scholars as according to this theory; it is workable especially in proximate and non proximate matter. According to the definition of matter and form hylomorphism theory, is not workable with regards to body and soul. Matter and form According to Aristotle, the fundamental question is not “Is X matter?” but rather “what is the matter of X?” (Statile, et al. 2006). Aristotle, therefore, defines the matter...
