Information processing Essay Example for Free

Information processing Essay Discuss how information processing varies between individual, team and racquet athletics.  Sport contains mainly perceptual motor skills so it is important to select the correct skill for the situation. The process used to select the correct skill is called the information processing system or the DCR process, because we Detect information, Compare it with previous experiences and then react.  Welford said that all information is taken in as stimuli through our senses. It is then stored in the short term memory before being sorted, if the stimulus is relevant to the current skill then it is stored in the short term memory where it is compared to previous experiences in the long term memory. Then a decision is made as to what action to take based on this comparison. The action that was performed and the outcome from this action are then stored in the long term memory for future reference. Welfords model is shown below:  This model makes a performer react in the way that they do to a situation but there are many factors that can influence what action the performer decides to take. These include; time available, number and intensity of stimuli, experience, anticipation, fitness and motivation of the performer. The effect these factors have on a performer will vary from individual, racquet and team sports.  The time that you have available to process the incoming stimuli differs in each sport. For example in rugby, which is externally paced, you have a small amount of time to process the stimuli and make a decision because there are usually many defenders around you. Tennis players also have very little time to react because the ball is usually travelling at a high speed and if they dont make a decision and return the ball they will lose the point. However in golf, an internally paced sport, the player can take as long as they need to make a decision because there ar e no opponents directly around them. There are three main types of stimuli that enter the sensory input these are;  Vision: is where a player will react to a visual stimulus such as the position of the ball or an opponent. These stimuli are easier to detect and react to if the stimulus is brighter. For example in tennis the ball is bright yellow which makes it easier to see. But there are also unwanted stimuli such as ball boys moving or crowd movements these stimuli are obviously irrelevant but they are still initially taken in which slows down the whole process. In an individual sport there are fewer visual stimuli for example in a 100m race the only real visual stimulus is where the finish line is in relation to you. Audition: this is all stimuli that are heard, for example when a team mate calls for the ball in rugby. Auditable stimuli are hard and processed easier and faster if they are loud and clear. There are also irrelevant auditable stimuli such as crowd noise these will slow down the information processing model.  Proprioception: this is made up of three components;  Equilibrium: this is an awareness of your body position and balance. We can tell if we are about to fall over and where we are in relation to objects. Team sports are more likely to have an uneven playing surface which means that your balance will have to be constantly adjusted as you are running. But in individual and racquet sports the playing surface is fairly constant with the exception of golf, where a stance may have to be altered to adjust to the surface. Kinaesthesis: this is where the body senses the muscle movement and contraction it is sometimes known as muscle memory. It is if the movement feels right to the performer. It is developed through practice and experience one example would be a conversion kick in rugby the player may take there step away from the ball in the same way they usually do but they may just feel that they are not in the right place. It doesnt apply as much in team games as in individual and racquet sports apart from set plays.  Tactile sense: this is the feeling of pressure this is important for all sports. It can be affected be the weather conditions because cold weather affects our ability to feel effectively. The short term sensory store is where all information is stored for a split second before it is processed. All relevant and irrelevant information is stored in here before it is replaced and lost. This does not differ between sports only what enters it does.  The perception stage is where all the information that has come from the short term sensory store is processed. This is when irrelevant information is thrown away and useful stimuli such as where the ball is, is kept to make a decision and stored in the STM. This will vary between individual, racquet and team sports because of the amount of stimuli. In team sports there are more stimuli so it takes longer to sort through whereas there are relatively small amounts of stimuli in individual sports so it wont take as long to sort them out. It also differs depending upon whether the performer is experienced or not as it will be easier for a expert to sort through the stimuli because they have more experience. We sort through the st imuli with selective attention and take only the important pieces of information because only around 7-10 pieces of information can be stored in the STM. The information passed on from the perception stage is then stored in the STM. Because only 7-10 pieces of information can be stored an experienced player may chunk information together so that the position of all players is one piece, but a beginner may not be able to do this so each player may be a separate piece. Team sports would be much more affected because of the amount of information so not all stimuli can be stored so a poor decision may be made but less poor decisions will be made in an individual or racquet sport because there is less information. The LTM holds information on movement patterns and the results of using them in certain situations and can hold them for a lifetime. Team sports have many memories but individual sports may have less.  The decision making process is where whats happening now (in the short term memory) with what has happened previously (in the long term memory). In the LTM the performer will be looking for similar situations and actions and their outcomes. This makes team games decision making process a lot longer because of the vast amount of information and possible actions to take. Whereas in an individual sport there is much less information and less possible actions. The motor output is the performance of the chosen skill. One example may be for a badminton player to put in a drop shot because the opponent is at the back of the court. The action is referred to the muscle movement in the LTM. The action and its consequences are then stored in the long term memory for future reference.  Individual sports, because they are individually paced, make them the simplest in the IP model. Also because there are fewer stimuli there is a shorter reaction time which gives the performer more time to carry out the IP model which should result in a better decision. Racquet sports are externally paced due to the fact that there is an opponent; this means that there is less time for the performer to react. There are some irrelevant stimuli which will slow down the IP model which means it takes longer to decide than in an individual sport but not as long as in a team sport because there are fewer possibilities for what action to take.  Team sports are externally paced which reduces the time available to react. Also there are much more irrelevant stimuli in team sports, this will lengthen the IP. The IP will also be lengthened due to the complexity of most team games because there are more situations and possible responses to choose from. Bibliography Advanced PE for Edexcel Heinemann by F.

The Importance of Sleep, Nutrition, and Exercise Essay -- Health Nutri

The Importance of Sleep, Nutrition, and Exercise Many students today ask why they are so tired all the time. It also seems that people in college become more stressed out either because of grades or because of work. All people need to do is get the right amount of sleep, eating well, and exercise in order to feel better about themselves and feel good in general. This is not a short process. Most experts say that it takes about twelve weeks in order to see results. But, it is guaranteed that after that duration of time one will see a vast improvement in oneself. Sleep is something that most people take for granted. It is the one thing that people are willing to compromise even more then food or money. It is estimated that between 40 to 60 million Americans are sleep deprived. Different people can get by with different amounts of sleep. There are some that can survive the next day with only a few hours. Then there are always others who cannot be called after 9:00 because they need those good solid 10 hours. The average person actually needs anywhere from between 7-9 hours a night. Why does one need sleep? When human bodies do not get enough sleep they tend to lose strength, the immune system decreases, and there is an increase in blood pressure. As students, it can effect concentration, memory, logical reasoning, and ability to do math. Now that the problem is known here is how to fix it. Dr. Stanley Coren, a professor of psychology at the University of British Columbia, focuses on consistency. The body needs consistency. This can be fulfille d by simply going to bed at the same time every night and waking up at the same time every day. But, it is important to note that making up for lost sleep on the weekends is a big negative. It is preferable that if one likes to sleep on the weekends wake up at the same time Saturday and Sunday. When going to bed it should take about 15 to 20 minutes to fall asleep. If a half-hour has gone by and one still is not asleep one should get up and do something relaxing (i.e. take a warm bath, read, watch TV, etc.). Rita Mattson, a Certified Personal Trainer and Stress Management Counselor, makes the suggestion of drinking warm milk before retiring to bed because milk contains a high dosage of L-tryptophan which is a natural sedative. Sleep is just as important as any other part of taking good care of ones self.

There are two types of sports bras: compression bras and encapsulation, harness-type bras. The first works better for smaller breasted women because of the fit and the second tends to work better for larger women. When choosing the correct one for you take into account: the fit, how much support it is giving for the exercise that is going to be done, fabric (does it absorb moisture well), seams and stitching to avoid chaffing, and mobility. After taking all these into account one can be assured that he is well prepared for the exercise routine.   Ã‚  Ã‚  Ã‚  Ã‚  In conclusion, all the factors mentioned above can lead to a less stressful life. Sleep can help the body relax to deal with everyday pressure. People who eat a diet low in refined carbohydrates, sugar and caffeine, and high in whole grains, have shown a greater ability to cope with stress as in contrast to those who consume the opposite. Exercise, as well, is a way to release stress and tension (i.e. running, kickboxing, stair stepping, etc.). If one keeps all the factors in mind a healthier happier life can be achieved.

Attracting Cockroaches with Different Substances

Reason: The reason I did this project was because I am absolutely fascinated by cockroaches. I think they are really interesting. It also makes me happy that I’m the only person I know of who is not scared of cockroaches. We have cockroaches that will come into our house to escape from the cold outside, so I thought, why not get rid of some of them? But I had to know what kind of bait to put out for them in order to accomplish this. So that is how I came up with this. Hypothesis: If the peanut butter, the butter, the cheese, and the bread are tested, then the butter will attract the most cockroaches. If the peanut butter, the butter, the cheese, and the bread are tested, then the bread will attract the least amount of cockroaches. Experiment What I did: Well, first I put four 4 by 10 sticky traps on our counter. Then, I got out some butter, some peanut butter, some bread, and some cheese out. After that, I got a tablespoon and scooped the substances out. I put the tablespoon of each substance on its own sticky trap. The butter on one, the peanut butter on another, and so on and so forth. Then I turned off the light and went to bed. When I got up, I got my data book out and went out to our counters. When I turned on the light, I counted how many cockroaches were on each sticky trap and I recorded my results. I tested this out ten times, and each time I recorded my results. Discussion Comparing: It was very interesting because according to my research, cockroaches like moist substances that they can easily pick up. But instead of going for the moist substances I put out, they went for the dry ones! Another thing I didn’t look at before was the temperature. The temperature really affected my results. According to my research, cockroaches can be seen the most inside houses when it is cold outside. And my results proved that it was true. When I did my project, it showed that as the temperature got colder, more and more cockroaches got stuck on the sticky trap. Uncontrolled Events: I think one uncontrolled event was the temperature. The temperature fell while I was doing my project. Usually, cockroaches will come indoors to escape from the cold outdoors. More cockroaches came in when the temperature dropped. Another thing I couldn’t control would be the exact place I put the sticky traps. I mean, I did put them on the counter, but I couldn’t put them all in the exact same place. What if a cockroach was just making his way across the counters when he got stuck on the sticky trap? What I would have done differently: If I had to do my project again, I would add in the temperatures of the night as well, because it really does affect my results. Either that, or I would make sure the temperature was pretty much the same each night. If it wasn’t around the temperature that I wanted, I would wait for the next night. I would also have added more bait to test because four traps really isn’t that much. Other Experiments that can be done: Some other experiments that can be done would be like, how the temperature effects on how active the cockroaches are, or what traps trap cockroaches best. You could also see if cockroaches are more active at night or in the daytime. According to my research though, cockroaches like to come out at night, while it’s still dark out, because to them, light means that somebody is there and can hurt them. But when it’s dark out, that’s the signal that everybody is asleep. One last test somebody could do, would be how long a cockroach could survive without food or water. Would it be affected if they had been fed a lot before the experiment started? What if they had only been fed a little bit before the experiment started? Conclusion Results: My results showed that the roaches went for the bread and cheese more than the butter and peanut butter, so my hypothesis was wrong. Each night, hardly any cockroaches went for the butter and peanut butter. They would mostly all go to the bread and cheese.

Essay on Hamlets Procrastination And Co - 919 Words

Hamletamp;#8217;s Procrastination and Cowardicenbsp;nbsp;nbsp;nbsp;nbsp;In William Shakespeareamp;#8217;s play Hamlet, Hamlet is a loyal prince who vows to avenge his fatheramp;#8217;s murder. When Hamlet discovers the painful truth about his fatheramp;#8217;s death, he is left with feelings of hatred and resentment in his heart towards the murderer, Claudius. Although Hamlet is a very noble and sophisticated man, he struggles with the issue of avenging his fatheramp;#8217;s death. He swears his revenge will be quick, however, this is not the case. Since Hamlet is more into philosophizing than action, he thinks about his intention to kill Claudius. The more he thinks about his intention, the less he is able to execute it.

His attitude soon changes when he realizes that he is plotting to commit treason and the enormous burden that comes along with that. He is scared. The reason for his first delay of action, according to Hamlet, is that he is doubting the existence of the ghost and whether it really was the spirit of his late father or just an evil spirit. Hamletamp;#8217;s excuse for doubting the ghost is displayed in his actions; amp;#8220;Be thou a spirit of health or goblin damnamp;#8217;d, Bring with thee airs from heaven or blasts from hell, Be thy intents wicked or charitable, Thou comamp;#8217;st in such a questionable shape; (Shakespeare, p. 59). Because Hamlet doubts the ghost, he cannot and does not kill the King at this point in the play. Time continues to pass by as Hamlet is indecisive. The conviction and determined attitude that Hamlet possessed earlier has now been lost and his procrastination becomes quite evident. He engages in meaningless activities, such as conducting small talk with Rosencrantz and Guildenstern.
