Advantages of visual object and space perception battery

Advantages of visual object and space perception battery Ans. Neuropsychological assessment is incomplete without the visual and space perception (Warrington shape detection, incomplete letters, silhouettes, object decision, dot counting, progressive silhouettes, position discrimination, number allocation and cube analysis (Warrington & James, 1991 as cited in Gorayska & Mey, 2004). Advantages of VOSP Brenda Rapp (2001) has stated that, â€Å"highly sophisticated methods of cognitive assessment can be developed if one uses as a starting point a detailed theory of relevant cognitive system† (Rapp, 2001, p.4). Good examples for theory based assessments methods for visual perception are Birmingham Object Recognition theory (BORB) (as given by Humphreys & Riddoch, 1993) and VOSP (Warrington & James, 1991). VOSP is made on Warrington’s model (Warrington & McCarthy, 1990 as cited in Lara et al., 2004). The model puts forward three subtypes of impaired object recognition. They are, â€Å"disorders of visual sensory discrimination † (Lara et al., 2004, p.386), apperceptive agnosia and associative agnosia. â€Å"Disorders of visual sensory discrimination reflect selective deficits affecting sensory processing including acuity, shape, discrimination and colour discrimination† (Lara et al., 2004, p.386), apperceptive agnosia is impaired object perception (Lara et al., 2004) and associative agnosia is when an individual is unable to derive meaning of the object presented despite having normal perceptual and sensory abilities(Lara et al., 2004). Thus, it can be inferred that object perception is not possible without object recognition in Warrington’s model (Lara et al., 2004) and it points out that object perception is an, â€Å"adequate integration of sensory, perceptual and representation information (Rapport, Millis & Bonello, 1998) in a complex analytical task that integrates perceived details into an organized structure (McCarthy &Warrington, 1990)† (Lara et al., 2004, p. 386). Cogn itive state of visual perception can be better understood with VOSP in normal and pathological population (Lara et al., 2004). For example, when VOSP was administered to patients of Alzheimer’s disease, impairment was found only in the silhouette subtest of VOSP (Binetti et al., 196 as cited in Lara et al., 2004). This suggests that early perceptual processes are still intact in patients who are in the initial stage of Alzheimer’s disease (Binetti et al., 196 as cited in Lara et al., 2004). VOSP is clearly a test of object recognition and space perception and nothing else. The is due to the reason , VOSP is made of different tests which includes tasks which are so designed that they assess specific dissociable aspects of object and space perception (Lawrence et al., 2000 , p.1350). Every task of the test focuses on a particular aspect of visual perception being completely independent of other cognitive and motor processes (Lawrence et al., 2000). Hence, VOSP can be reg arded as a sensitive test battery. The authors of VOSP have stated, â€Å"Any number of the eight individual tests may be administered and there is no prescribed order (Warrington & James, 1991, p.7)† (Merten, 2006, p.460). This is a very useful thing to do. It is very practically next to impossible to administer the complete set of tests of VOSP as part of neuropsychological assessment because it will be quite a time consuming process (Merten, 2006). Moreover, as advised by Lasogga & Michel (1994 in Merten,2006), easy to use screening measure can be used to test initial visual perception on the suspected group and only those showing visible deficits will be asked to go through the complete assessment (Merten, 2006).

Marketing Plan - Essay Example The target market of our company will be the major schools and college in the locality. The sports service will provide a platform where the school sports teams will be provided the opportunities to participate in games. This service will be different from other kinds of sports clubs and school sports clubs and more details will be provided in the following sections. The growing activities in sports are increasing the need of managers and directors with high level of knowledge (CHOCANO, 2004). The six challenges identified by McKinsey for a sport business to be a successful include Players’ salaries, Changes in technology, Pricing, Internationalization, Innovation and Illegal activities by athletes (Patterson, 2004). Since the trends in sports industry vary from country to country, therefore, it is very important to conduct an analysis of the market, where we are planning to start our business. The economy of London has emerged out of recession and the growth rate is very slow and in 2010, the economy is expected to face various hurdles. In a report (2010) it has reported that London economy has faced a decline in average annual growth rate of passengers, a rise in new orders and a rise in expected house prices (London Gov, 2010). In a survey conducted by World Bank in 2010, ‘Doing Business 2010: Reforming through Difficult Times’, it was found that UK is the fifth country in the world and first country in Europe in terms of ease in doing business (London Gov, 2009). Moreover, London Gov (2009) report also shows that the output of goods and services in London has increased in August 2009 and business activity recorded by Purchasing Managers’ Index (PMI) in August was 54.2 as compared to 52.1 in July. It shows the increase business activities in London Economy. The Government of UK only seeks to assist the sports organizations with funding and strategies and does not control the sport. Moreover, sports in UK are also

Supply and Demand in substitute products (cell phones) in our current Research Paper

Supply and Demand in substitute products (cell phones) in our current time - Research Paper Example To illustrate, as Luo (2006) points out, if government imposes higher tax rates on cell phones, consumer demand for cell phones would decline whereas demand and supply would increase when the government sets favorable tax rates. Government policies regarding imports can also significantly affect the demand and supply in the cell phone industry. Similarly, as Pierskalla and Hollenbach (2013) point out, technology also plays an inevitable role determining the demand and supply of cell phone products. The industry analysts say that technological innovations can reduce the production costs of products like cell phones and this situation in turn would increase their demand and supply. In addition, advancements in technology would assist cell phone manufacturers to offer technologically improved products to customers and consequently the demand and supply would be improved. Evidently, cost of production is inversely related to demand and supply (Hortman, n.d.). When the cost of production increases, manufactures will be compelled to charge higher prices for their products and this in turn would lead to a decline in demand and supply. In emerging countries like China and India, labor costs are relatively low and therefore production costs can be notably reduced. According to Sugden (2022, P. 42), nature of the industry can influence the demand and supply to some extent. Today cell phones have become increasingly popular and therefore people consider it as a necessity product. As a result, the supply and demand of cell phones would remain to be stable regardless of small variations in price. Degree of Competitiveness Degree of competitiveness is very high in the cell phone industry because there are numerous potential players like Nokia, Samsung, LG, and Sony operating in this sector (see Figure 1). Price competition is very common in the cell phone indus try because every marketer tries to improve the demand and supply of his products in order to obtain an edge over competitors by taking advantages of price sensitivity of modern customers. Therefore, a cell phone marketer cannot sustain in the industry if he fixes prices above the par industry prices. In addition, cell phone companies compete based on technology also. To illustrate, today cell phone marketers integrate technological features like video facility, high MP cameras, Wi-Fi, Bluetooth, GPRS, dual sim, external memory into their products with intent to retain customer interests. In order to address the intense market competition, the firm’s managers should particularly try to keep their labor costs and material costs low and thereby minimize costs of production. For this, managers need to establish their production plants in countries where cost of raw materials and labor is relatively low. Effects of Macroeconomic Events A decline in the relative value of the US do llar can have a significant impact on the demand and supply of cell phones. Evidently a declining value of the US dollar would directly lead to an increase in US import prices (Effects of a Falling Dollar). It is clear that the US cell phone market is dominated by foreign companies and hence a fall in the relative v
