Imagery in Sports
Athletes are always on the look out for techniques that will allow them to get better at their game. Whether it is a golfer who is looking to break his best score or a hockey goalie who is trying to get a shutout in the next game he plays, amateur and professional athletes are constantly trying to find ways of improving their performance. One performance enhancing technique that has been the subject of many empirical studies and theoretical speculation is the practice of imagery. Defined in its most general sense, imagery is ââ¬Å"an experience that mimics real experience. We can be aware of ââ¬Ëseeing' an image, feeling movements as an image, or experiencing an image of smell, tastes, or sounds without actually experiencing the real thingâ⬠¦ it differs from dreams in that we are awake and conscious when we form an image. â⬠(Munroe-Chandler & Hall, 2011, p. 370) Applied to the basic problem of improving athletic performance, imagery exercises might consist of visualizing a hole in one for a golfer, or imagining what it feels like to play the net in the next game for a goalie. Imagery is connected to but distinct from the technique known as ââ¬Ëmental practice,' where an athlete rehearses his or her strategy in competition. There are many various kinds of imagery techniques that exist, but the question of whether imagery really helps athletes to improve is still a matter of some debate, as is the question of how imagery works. The following paper will look at the research that exists on imagery as a technique athletes can use to program their minds. It will conclude, on the basis of this research, that imagery can indeed help people's athletic performance, but that it should be considered as a complement rather than a substitute for practice and training. In order to rigorously understand the various ways that imagery can interact with and potentially improve athletic performance, some kind of standard benchmark is required. It was for this reason that the Sport Imagery Questionnaire (SIQ) was designed. The SIQ is an analytic tool that allows sports psychologists to make fine distinctions between the various functions of imagery as it is employed by athletes (i. . motivation versus concentration) and the levels at which imagery works (i. e. specific versus general). (Hall, Mack, Paivio, & Hausenblas, 1998, p. 74) This analytical framework is used by many other researchers in the field to quantify and make predictive claims about the effects of various kinds of imagery on athletic performance. Weinberg (2008) defines imagery as ââ¬Å"using all the senses (or at least all the senses that are appropriate) to create or re-create an experience in the mind. (p. 2) Weinberg is careful to distinguish between earlier techniques of ââ¬Ëmental practiceââ¬â¢ that involved the review of particular strategies and thinking about performance and current techniques of mental imagery, writing that ââ¬Å"it is very different, for example, if a tennis player simply went over his strategy for how he would like to play an upcoming opponent versus actually imagining himself performing certain skills and strategies against a specific opponent. â⬠(Weinberg, p. ) In essence, mental practice is a ââ¬Ë3rd personââ¬â¢ technique in which an athlete verbally rehearses to himself how he is going to perform and what he is going to do if his opponent does a particular action, while imagery is a ââ¬Ë1st personââ¬â¢ technique where an athlete lets go of words and tries instead to place himself in the performance situation mentally. Needless to say, the hard and fast division between the two is difficult to observe or even practice in reality. Most people in their daily thoughts entertain both images and talk in their minds, and the same applies to athletes using various imagery or mental practice techniques. Using mental practice, an athlete ââ¬Ëtalks himself throughââ¬â¢ a performance scenario, proposing various courses of action based on an opponents previous history. Using imagery, an athlete rehearses the various body movements that are to be used in successfully performing the sport they are training for in their minds eye. A tennis player using mental imagery might imagine how the court will feel under his feet and how the ball will bounce. He will envision himself running up to or away from the net to return the various volleys of his opponent. Both mental practice and imagery, according to Weinberg, did in fact prove successful for athletes in improving their performance, but many of the gains that athletes experienced were solely anecdotal; in other words, their performance was not subject to detailed empirical scrutiny, nor was the technique of mental practice developed to a very great degree. As Weinberg notes, ââ¬Å"the effectiveness of imagery, per se, isâ⬠¦ difficult to tease out, because the meta-analyses typically combined effects from studies that used various forms of mental practice to arrive at one overall effect size. â⬠(p. 2-3) Weinberg also notes that the field of mental imagery in sports has become more rigorous in the past decade or so, noting that ââ¬Å"current imagery research (as well as the practice of imagery in the field) often involves detailed scripts that focus on achieving particular outcomesâ⬠¦ arlier mental practice research was generally not this rigorous in this regard or simply was not interested in this type of mental preparation. â⬠(Weinberg, 2008, p. 3) Post, Wrisberg, and Mullins (2010) describe the results of a study on imagery where basketball players on a girlsââ¬â¢ highschool team were asked to participate in a guided imagery exercise before half of the games the girls played during their season. The authors collected data on both the victories that the girlsââ¬â¢ team had won and also the number of made versus missed free throw shots. Subjecting the data to a 2 by 2 chi-square analysis, these authors concluded that the imagery technique used by the girls before their games significantly improved their chances of winning and improved their chances of making free throw shots. With respect to their results, Post, Wrisburg, & Mullins (2010) write that ââ¬Å"imagery alone or in combination with other psychological skills (e. g. , relaxation) can enhance the competition-related thoughts and emotions of athletes. The documented effects of imagery include improved self-confidence, increased motivation, improved selective attention, and reduced or more effectively managed pre-competitive anxiety. â⬠(p. 2) Why this is the case is still a matter of much controversy, with explanations of the effects of mental imagery on athletic performance ranging from imagery as a rehearsal that prepares the body to imagery as a kind of attention focusing tool that makes athletes concentrate better. In the study these authors describe, 16 female varsity basketball players were asked to run through an imagery script created by the coach (Mullins). The script was based on several recommendations from sports psychology literature, beginning ââ¬Å"with a brief centering phase that involved deep breathingâ⬠¦ followed by a stimulus proposition phase where players were instructed to re-create possible game situations surrounding the free throw shot and a response proposition phase that consisted of the actions of the entire shot from the time the player began her pre-shot routine until she saw and heard the ball swish through the net. â⬠(p. 6) Results reported by Callow and Hardy (2001) come to a similar conclusion with respect to the efficacy of mental imagery in improving athletic performance. In their study, they apply Martin, Moritz, and Hallââ¬â¢s (1999) model to a sample of 123 female netball players in Wales. In their analysis of the positive results they found in using imagery in netball, Callow and Hardy distinguish between two kinds of confidence: sport confidence and self-efficacy. The first ââ¬Å"refers to the belief that an athlete possesses about his or her ability to be successful in sport in generalâ⬠whereas the second ââ¬Å"refers to an individualââ¬â¢s belief in his or her capabilities to be successful in executing specific tasks and skills in specific situationsâ⬠¦ (Callow & Hardy, 2001, p. 2) They propose that the mechanism by which imagery works to improve performance is directly related to the increase in the feeling of self-efficacy that athletes achieve through using directed imagery exercises. Using the SIQ framework designed by Hall et al. (1998), Callow & Hardy (2001) distinguish between five kinds of imagery: Cognitive General (CG; e. g. , I imagine executing entire plays/programs sections just the way I want them to happen in an event/game), Cognitive Specific (CS; e. g. I can easilty change an image of a skill), Motivational General-Mastery (MG-M; e. g. , I imagine myself working successfully through tough situations), Motivational General-Arousal (MG-A; e. g. , I imagine the excitement associated with competing), and Motivational Specific (MS; e. g. , I imagine myself winning a medal). (p. 2-3) These five types of imagery correspond to those employed by the Sport Imagery Questionnaire (SIQ) that Callow and Hardy used to monitor the effectiveness of imagery exer cises amongst the studyââ¬â¢s sample of female netball players. The authors found not only that the use of different kinds of imagery contributed to greater athletic success, but also that different types of imagery were used by players of differing skills; in other words, lower skilled netballers tended to employ MG-M and CG more often than MG-A, while higher skilled netballers used MS. This indicates that different kinds of imagery possess differing levels of ââ¬Å"pertinenceâ⬠to an athlete. (p. 12) For instance, a higher skilled netball player will have been in a situation where they are close to winning a championship or medal, so this kind of imagery is something they can easily access. Novice netballers, on the other hand, will be more concerned with the execution of basic moves and strategies, and will focus their mental resources on this aspect of the game. Similar findings of the positive effect of imagery on athletic performance are reported by MacIntyre & Moran (2007), who define the process of mental imagery as ââ¬Å"a cognitive performance-enhancement technique that is used extensively by athletes, coaches and psychologists to facilitate skill learning and performance. (p. 1) The authors go on to state that imagery techniques in enhancing athletic performance have become so prevalent that they are now considered to be a ââ¬Å"central pillarâ⬠of psychology in sports. (MacIntyre & Moran, 2007, p. 1) They divide the history of imagery research into two ââ¬Ëwaves,' one wave consisting of empirical research into the success of ââ¬Ëmental practice,' defined as ââ¬Å"the systematic use of mental imagery in order to rehearse physical actions. â⬠(p. ) While this first wave went far in demonstrating a connection between using mental practice and athletic success, it was weakened by the fact that it had no theory to guide its findings. In response to this lack of theory, the second wave MacIntyre and Moran describe attempts to connect the success of mental practice with a larger model or taxonomy that categorizes different types of imagery and different imagery methods. Despite this new trend in sports psychology research, findings in imagery studies continue to suffer from some significant drawbacks that undermine their conclusiveness. One drawback MacIntyre and Moran (2007) point out is that most of the imagery studies that exist have used beginner athletes rather than professional or ââ¬Ëelite' athletes. This is a problem because it is difficult to generalize about the success of mental imagery in creating better performance in athletes in general from only a particular set. Beginning athletes, simply by virtue of their novice status, might demonstrate significant athletic performance gains with or without imagery. Another weakness of most studies these authors point out is that they do not take into account beliefs athlete's have about their own imagery processes. In other words, many imagery studies do not take into account the ââ¬Ëmeta-imagery' that athletes might engage in concerning how successful their imagery techniques will be in improving their performance. This is clearly a drawback with respect to drawing conclusions about the ultimate efficacy of imagery, because it might not be the activity of imagery per se that helps an athlete succeed, but rather their belief that their imagery techniques will help them. Findings presented in Kim and Giacobbi (2009) suggest that beliefs about the efficacy of imagery as a technique are just as, if not more important in predicted better athletic success than the technique itself. 16 middle-aged participants between 35 and 65 were asked specific questions about the use of imagery in connection with exercise. Questions concerned ââ¬Å"where, when, what (content), and why (function)â⬠¦ [participants used] exercise imagery. â⬠(Kim & Giacobbi, 2009, p. 5) In addition to these questions about imagery content, participants were also asked about their own feelings concerning the impact imagery had on their exercise routines. On the whole, imagery was believed to be an activity that improved participants' concentration and performance. (p. 18) The foregoing studies suggest a number of conclusions about the use and effectiveness of imagery for athletes who are looking for techniques to improve their game. One of the most obvious conclusions is that imagery does appear to enhance athletic performance, but the degree to which it does so depends in large part upon the pre-existing skill level of the person being considered. For beginners or novices at a particular sport, imagery can have a dramatic effect on performance, while for athletes who are more advanced and at a higher skill level, the effects of imagery in performance are less pronounced. A second conclusion concerning the use of imagery in sports is that the effect imagery has on performance depends to a large degree upon the beliefs of the individual with regard to the technique's effectiveness ââ¬â a person who believes that imaging a performance will help them creates, in a sense, a self-fulfilling prophecy of their own success. This is somewhat equivalent to the ââ¬Ëplacebo effect' that is common in the use of drugs. Third, various studies have shown that different kinds of imagery are used by athletes at different skill levels. Beginning athletes will use imagery to create scenes of successfully blocking a shot, or making a basket, whereas advanced athletes image instead the winning of a competition or event. One aspect of imagery in sports psychology that remains an issue of contention is the precise mechanism by which imagery is able to assist athletes perform better. As discussed above, different studies have proposed different ways in which imagery is effective, but none of these proposed mechanisms have been demonstrated unequivocally as being the only correct one. Most likely, the mechanism by which imagery operates is a complex one that involves not only the inner rehearsal of actions, thereby amounting to a kind of ââ¬Ëpractice without practice,' but also involves the heightening of concentration for the athlete. Regardless of its mechanism of action, it is clear that imagery is a technique (or rather, family of techniques) that promises much for athletes' performance. Needless to say, imagery cannot ever be used as a full substitute for physical training and practice. Imagine how a football team would perform if, instead of practicing, they merely ââ¬Ëimagined' practicing for the week before their big game! However, used in conjunction with rigourous training programs, imagery is an excellent psychological complement that can help athletes improve.

This may include information on the existing knowledge on the subject and gaps in our existing knowledge. The context of this material is urban Australian real estate industry. While major industries would require programs that can recruit the right employees, in urban Australia, getting the individual to work is an issue. The main points in this material are that Australia shows that the safety of employees within the industry is based on the use of technology to provide details regarding construction measurements and planning. Mismatch between program-based decisions and human-based manual work is reported to result in higher number of injuries and deaths within the industry. Focus on the incidences in Makkah Cityââ¬â¢s construction industry shows that the nationalââ¬â¢s policy and preparedness for disasters does not support the companies involved with construction (Australian Industry Group, 34). The key concepts in this material are construction workersââ¬â¢ health and safety at their places of work and are grounded on the Herzbergââ¬â¢s two-factor theory on motivation and hygiene. Based on the information regarding other nationsââ¬â¢ safety standards and the stabilities of various industries, Australia builds on policies that aim at reducing the worker fatalities by at least 20 percent and the rate of claims made within a week or several weeks by 30 percent (Australian Industry Group, 33). 6.

[Banking and Management] Assess the advantages and limitations of universal banking OR all purpose financial institutions - Essay Example tional economic investments, the Chinese banking sector has undertaken the strategies of integrating investment services, advisory and underwriting service, home finance and asset management under the same umbrella of the commercial services provided the banks. The universal banking service offered by the Chinese state-owned banks has certain advantages as well as the limitations. On one hand, the aspect of universal banking enables the banks to increase their sales revenues and profitability by catering to the investment demands of the worldwide markets apart from the commercial services. The limitations of offering universal banking products and services lay due to the fluctuation of international economic conditions and the fluctuation of interest rates, exchange rate that would increase the risk exposure of the investment services. The concept of universal banking includes a wide range of financial services provided by the banks in order to cater to the regular banking as well as the investment needs of the customers. The aspect of ââ¬Å"all purpose financial institutionsâ⬠is related to offering comprehensive service to the customers that also help the banks to diversify the risk of their business. The various banking products and solutions that are offered under the system of universal banking includes savings and deposits accounts, loans and credit services, management of assets, investment service, underwriting services, financial analysis, advisory services, processing of payments, etc. However, banks may choose to offer specific products and services in a universal banking system depending on their specializations. The Chinese banks have been recently named by a magazine as the one of the worldââ¬â¢s largest and profitable banks in the world (Linda and Julapa, 2000, p.33). However, this does not mean that the Chinese banking sector is more resilient to the complexities of international economies. Although developments in the Chinese banking sector have

Battle of Okinawa Research Paper Example | Topics and Well Written Essays - 1000 words
Battle of Okinawa - Research Paper Example a period of 80 days, the ââ¬Å"Typhoon of Steeleâ⬠as it was referred to, raged on as the Allied Forces made headway in the battle to make Japan surrender. The attack itself took place on April 1, 1945. The Americans had sent in two United States Marine and Army Divisions to land via amphibious vehicle on the island of Okinawa. The Japanese troops were thought to number at least 150,000 covering ground, air, and naval troops. 10th U.S. Army Lieutenant General Simon Bolivar Buckner Jr. was in command of the Allied troops that consisted of III Amphibious Corps and XXIV Army Corps. Even though the Allied Forces had sent a formidable troop assignment to the island, the Japanese still felt that the war was going to end with them as the victors. After all, the Japanese were fighting on their home territory, 350 miles from the Japanese homeland. However the Americans had other plans for this battle as they pulverized the island of Kyushu. The Japanese by this point knew that the battle was lost and yet they soldiered on. The Japanese soldiers fought based upon honour and military logic. But the bombings of the American planes coming from the Marianas Islands would soon conquer Japan. Truth be told, there was too much land coverage in Okinawa for the troops that were first sent to cover. Thanks to the Army, the new 6th Marine Division, the war became a winnable battle for the Americans. Eric Hammel, noted Pacific War historian recounted the battle as follows: Coming to put their defense arrangement to the test was the Tenth Army. The new 6th Marine Division (1st Provisional Marine Brigade plus the 29th Marines and attachments) would land over the northernmost beaches on the western side of Okinawa a little south of the islands midpoint. It was to strike across the island, then turn north to pacify a little more than half of Okinawa on its own. To the right, the 1st Marine Division was also to strike across the island, then become part of the Tenth Army reserve.

Presentation and written submission Essay Example | Topics and Well Written Essays - 1000 words
Presentation and written submission - Essay Example Those trades that took place were carried out at substantial discounts. These disruptions in market activity had a fundamental role in the transmission and amplification of the US financial market. The global financial crisis of 2007 - 2009 led to uncertainty in the US financial market causing the problem of adverse selection. Adverse selection is a situation where only one party to a financial contract has better information as compared to the other leading to only low-quality products being available in the market. The aim of this paper is to discuss the role of adverse selection in causing reduced lending, investment and economic activity as a result of little willingness to lend among US lender. Adverse Selection Adverse selection refers to an asymmetric information problem which takes place before a transaction is carried out. It is when possible bad credit risks are the most active in seeking out loans. This therefore leads to the likelihood of those that are most likely to cre ate an undesirable/adverse result being selected (Philippon & Skreta, 2010, p. 22). For instance, those that seek to carry on big risks are more likely to be the most keen to take loans since they know they arenââ¬â¢t likely to pay it back. ... An assetââ¬â¢s market price will manifest the quality expected based on the quality of all assets that are for sale in the market if buyers canââ¬â¢t be able to assess its quality. Adverse selection can arise from this asymmetric information between buyers and sellers. Sellers of high quality assets will pull back from the market as prices fall hence leaving assets that are of only low-quality (lemons) for sale. The result may be the reduction or halt in the trade of the asset since buyers are wary they will be left with an asset that is overpriced (lemon) if they transact. Moreover, this leads to the credit crunch since such assets can no longer act as collateral for other transactions. In both post-crisis episodes and the global financial crisis of 2007ââ¬â09, adverse selection played a key role (Coval, Jurek & Stafford, 2009, p. 19). Increases in Uncertainty It gets more difficult for lenders to screen out good credits from the bad ones whenever there is a striking incre ase in uncertainty in financial markets. A reduction in investment, lending and aggregate activity is caused by lenders becoming less willing to lend due to their inability to solve adverse selection. The increase in uncertainty can grow out of a recession or failure of large financial or nonfinancial institution. However, uncertainty regarding interest rate dynamics and government policies seem to have in recent times of financial instability in developed market countries played a major role in reduction of investment, lending and aggregate economic activity (Caballero & Krishnamurthy, 2009, p. 86 - 88).

Texas Education Budget Cuts Essay Example | Topics and Well Written Essays - 500 words
Texas Education Budget Cuts - Essay Example The expression describes an act of desperation; a deal with the devil done to provide short-term relief that merely forestalls a now-guaranteed disastrous long-term consequence, for it turns temporary hunger pangs into inevitable starvation. To eat the next yearââ¬â¢s seeds is to fail to invest in the future. It is myopic generational theft that insidiously steals from tomorrow by mortgaging the future. Such is the same with Texasââ¬â¢ ill-conceived plan to cut public school budgets. Weââ¬â¢ve all heard the mantra that the future is high-tech and in Texas, even traditionally low-tech industries like oil exploration have gone high-tech. According to Southwest Economy: The history of Texas lies in cattle and oil. But increasingly, the future of the state is becoming linked with the ever-evolving high-tech industry. High-tech employment has grown more than twice as fast in Texas as it has in the nation during the 1990s...The high-tech expansion has had an indirect impact on the state's economy by keeping other industries humming [...] One of the best examples of the indirect effects is the impact on the state's construction and real estate industries.

Formal business memo Article Example | Topics and Well Written Essays - 500 words
Formal business memo - Article Example When the cost of living surges, the minimum wage should also rise. This is because workers face significant strain while earning figures that do not consider inflation. In the end, the quality of life diminishes as a large number of families are forced into poverty. It is essential for workers to feel that the state takes care of their welfare. Raising the minimum wage is one of the principal ways in which the state intervenes for workers who are majorly defenseless against businesspersons. It is essential to note that the current minimum hour wage of 7.25 per hour does not care of taxes that every employee faces. At the end of the day, most workers probably earn $ 4 per hour after taxes. This act will also favor the business community since higher pay raises the morale of workers. A workforce with increased morale easily manifests higher productivity. Besides, the city should target increased expenditure towards rising out of the consequences of the recession. This is only possible if workersââ¬â¢ purchasing power increases. When the city raises the minimum wage, the action will affect more than 400,000 workers who make a third of Chicagoââ¬â¢s workforce (CBS Chicago 1). This figure considers casual workers in areas such as hotels. Hotel workers in Los Angeles recently won a $ 15.37 minimum wage policy. This happened after unions and right groups formed advocacy groups for the same. This is the highest minimum wage figure among all the states. It is crucial to highlight that hotel workers were the originators of the idea. This suggests that the minimum wage issue mostly affects the casual workers. Casual workers are predisposed to exploitation by business owners because such jobs do not require special skills. Consequently, the minimum wage is a serious concern for SMEââ¬â¢s and the informal sector such as hotels. A higher minimum wage increases the cost of business. A
