Change Blindness and Visual Memory: Research and Theories

Change Blindness and Visual Memory: Research and Theories What is change blindness and what can it tell us about attention? Recent research on visual memory has shown that people have great difficulty in detecting obvious changes to an object, such as colour and size, if the change occurs simultaneously with a distraction. The term change blindness is used to describe this phenomenon and much research has been carried out to further our understanding of the condition. Research on change blindness has also produced valuable information about how our visual attention is involved in the encoding process. A variety of tests have been developed to test the prevalence of change blindness and the results show that it is a robust phenomenon. Although change blindness was studied many decades ago it is only in the last decade that research in this area has increased dramatically. Earlier research relied on using shapes or novel objects to induce change blindness and therefore some argued that the condition was caused by artificial stimuli. However, Grimes (1996) showed that more natural images could be used to induce change blindness. Using a computer screen he showed observers photographic images of natural scenes and asked the observers to remember as much of the photograph as possible for a later memory test. However, during a saccade (when observers were visually scanning one object to another in the image) the image was altered. The observers were then asked if they noticed if anything had changed to the image. Invariably, observers were oblivious to the changes even when they were ma jor ones, such as two people exchanging heads. Although previous experiments had shown the existence of change blindness, Grimes 1996 study was the first to show that individuals can fail to detect major alterations to images. Moreover, Grimes used everyday natural images thereby bringing demonstrations of change blindness closer to everyday perceptual experience. Other similar studies also showed that different distracters could be used to induce change blindness. For example, during eye blinking (O’Regan et al 2000) or by applying mudsplats in the surrounding area of the objects that were changed (O’Regan et al 1999). The fact that distractions are needed to induce change blindness suggests that attention is needed for change perception. Without distracters it is very easy for an observer to notice any change that has taken place. This led researchers to investigate the role of attention in change blindness and now there is mounting evidence that attention plays a pivotal role in the condition. For example, in change blindness tasks it has been found that attention to objects can vary depending on the objects location and this can influence whether the change is detected. This has been demonstrated by studies such as Rensink et al (1997). They developed the flicker task which involves using an original and altered image that is repeatedly shown to the observer with the two images separated by a blank screen for a fraction of a second. As with other distracters the observers demonstrated change blindness by invariably taking a long time before they noticed the change to the original image (average being 40 repeats). Another interesting finding of this study is that the observers found it easier to detect changes to objects that were the centre of interest of a scene than objects that were of marginal interest even when the changes were of equal physical salience. This has also been found in other change blindness studies. Levin Simons, (1997), for example, found the same effect when they changed movie objects during a film cut. One theory to explain this finding is that focused attention is required to detect change. This makes sense as a change of any object is always accompanied by a motion signal and therefore attracts attention to the site of change. This allows the change to be observed. However, if the signal is too weak (e.g., because of distracters such as saccades or blanking) it will fail to draw attention to the location of the change which will result in change blindness (Rensink et al 1997). Change blindness can also be demonstrated in real-life situations. Simons and Levin (1998) carried out an experiment in which members of the public were approached by an experimenter who asked for directions. During their conversation two actors carrying a large occluder would walk between the experimenter and subject. At this point the experimenter would swap places with a colleague who would continue the conversation with the subject. The findings showed that some individuals failed to notice that the experimenter had swapped places with another person even though the differences between the two were obvious, such as size and different clothes. This study was important because it showed that change blindness could occur using complex stimuli usually found in the real world. Therefore, finding change blindness can occur in more naturalistic settings counteracted some claims that it was only caused by artificial disruptions, such as the blanking-out distracter in the flicker paradigm (Simons Rensink 2005). There are several theories that attempt to explain change blindness in relation to the interaction between attention and visual perception. For example, Rensink (2000, 2001) developed his coherence theory. This theory is based on several assumptions. First, prior to focussed attention there is an initial stage of processing across the visual field of view. This processing produces representations of several objects in the field of view, but the representations are not stable and therefore are quickly replaced by new stimuli at their location. Second, focused attention produces a very detailed and longer-lasting representation of the object. This allows the representation of the object to be more stable which can withstand brief interruption. Therefore, a change in a focused object will be easily detectable. Third, removing focussed attention will result in the representation of the object disintegrating and returning to the unstable state it was prior to focussed attention. From the above assumptions it follows that only changes made to objects that are the focus of attention will be detected. This can explain why change blindness is a common phenomenon, because any changes to an unattended object will not be detected. The assumption that attentional processes are crucial in underlying change blindness is a common one. For example, Hollingworth and Henderson (2002) agree with the assumption. However, they propose an alternative theory of the relationship between attention and object perception. They argue that detailed perceptions are formed when we look at objects which are the focus of attention. These representations are then incorporated into a mental map and information about these visual representations is then stored in the long-term memory. Therefore, multiple fixations of a scene will result in information accumulating in the long-term memory about local objects from both the attended and previously attended areas, and this forms a detailed representation of the scene as a whole (Hollingworth and Henderson 2002). There are several differences between Hollingworth and Hendersons theory and the coherence theory that have implications about understanding the role of attention in change blindness. First, if objects change, (e.g., disappear or move) sometime after they were attended to, according to Hollingworth and Henderson they would still be mentally visible for some time after the change. Therefore, any change has a good chance of being noticed. Whereas the coherence theory predicts that when attention is withdrawn from objects the mental representation of such objects disintegrate rapidly and therefore any change will result in change blindness. Second, unlike the coherence theory, Hollingworth and Henderson assume that detailed representations of most scenes are stored in the long-term memory. Therefore, any changes made to objects should be detected several minutes later. Finally, in the coherence theory it assumed that focusing attention on an object produces a very detailed image that ca n withstand a brief interruption, such as a saccade. In contrast, Hollingworth and Henderson believe that less detailed visual representations are made when the object is the focus of attention. To date, research has not provided clear evidence to support either Hollingworth and Hendersons theory or the coherence theory (see Simons Rensink 2005 for an overview). Therefore, further investigations are required to better understand the interaction between attention and change blindness. Change blindness is a robust phenomenon that has been demonstrated in many different laboratory and naturalistic studies. The overall assumption of the findings of change-blindness experiments is that attention seems to play a major role in determining the extent of the condition. The importance of attention in change blindness appears to arise because we do not maintain a detailed representation of what we have just seen. Otherwise individuals would have little problem noticing the obvious changes that occur between images. Change blindness studies have proved a useful tool in providing information about the processing mechanisms of attention, such as we direct attention more to objects of interest within a scene. However, although studies on change blindness have increased our understanding of attention there is much debate about the exact role of attention in change blindness. Further research is therefore required to fully understand the relationship between attention and change blindness and what other factors are involved in the condition. References Grimes J. (1996).

Urbanisation: City and Urban Areas

Introduction Urbanization is increasing in both the developed and developing countries. However, rapid urbanization, particularly the growth of large cities, and the associated problems of unemployment, poverty, inadequate health, poor sanitation, urban slums and environmental degradation pose a formidable challenge in many developing countries. Available statistics show that more than half of the world’s 6. 6 billion people live in urban areas, crowded into 3 percent of the earth’s land area (Angotti, 1993; UNFPA, 1993). The proportion of the world’s population living in urban areas, which was less than 5 percent in 1800 increased to 47 percent in 2000 and is expected to reach 65 percent in 2030 (United Nations, 1990; 1991). However, more than 90 percent of future population growth will be concentrated in cities in developing countries and a large percentage of this population will be poor. In Africa and Asia where urbanization is still considerably lower (40 percent), both are expected to be 54 percent urban by 2025 (UN 1995; 2002). Although urbanization is the driving force for modernization, economic growth and development, there is increasing concern about the effects of expanding cities, principally on human health, livelihoods and the environment. The implications of rapid urbanization and demographic trends for employment, food security, water supply, shelter and sanitation, especially the disposal of wastes (solid and liquid) that the cities produce are staggering (UNCED, 1992). The question that arises is whether the current trend in urban growth is sustainable considering the accompanying urban challenges such as unemployment, slum development, poverty and environmental degradation, especially in the developing countries. Urbanization defined Urbanization, simply defined, is the shift from a rural to an urban society, and involves an increase in the number of people in urban areas during a particular year. Urbanization is the outcome of social, economic and political developments that lead to urban concentration and growth of large cities, changes in land use and transformation from rural to metropolitan pattern of organization and governance. Major causes of urbanization Natural population increase (high births than death) and migration are significant factors in the growth of cities in the developing countries. The natural increase is fuelled by improved medical care, better sanitation and improved food supplies, which reduce death rates and cause populations to grow. In many developing countries, it is rural poverty that drives people from the rural areas into the city in search of employment, food, shelter and education. Most people move into the urban areas because they are ‘pushed’ out by factors such as poverty, environmental degradation, religious strife, political persecution, food insecurity and lack of basic infrastructure and services in the rural areas or because they are ‘pulled’ into the urban areas by the advantages and opportunities of the city including education, electricity, water etc. Even though in many African countries the urban areas offer few jobs for the youth, they are often attracted there by the amenities of urban life (Tarver, 1996). Processes of urbanization One significant feature of the urbanization process in today’s local governments is that much of the growth is taking place in the absence of significant industrial expansion. Although local municipalities are fast urbanizing, mega-cities defined as cities with 10 million inhabitants or more are few. Urbanization also finds expression principally in outward expansion of the built-up area and conversion of prime agricultural lands into residential and industrial uses. An alternative to the present expansion of the urban population across a wide area of the country in order to save prime land for agriculture is to construct high-rise buildings and promote commercial development in specific zones, which would depend on effective, appropriate technology and resources. The urbanization processes are largely driven by market forces and policies of local governments that lead to simultaneous processes of change in livelihoods, land use, health and natural resources management including water, soil and forests and often reactive changes in local governance. Government development policies and budget allocations, which often favour urban residents over rural areas, tend to pull people into the urban areas. In the cities, public investment, which often misses the urban poor, with expenditures biased towards the higher-income classes and poverty among vulnerable groups such as new migrants force them into slums and squatter settlements. Challenges of urbanisation Cities throughout the world exhibit an incredible diversity of characteristics, economic structures, levels of infrastructure, historic origins, patterns of growth, and degrees of formal planning. Yet, many of the problems that they face are strikingly familiar. For one thing, as cities grow, they become increasingly diverse. Every city has its relatively more affluent and relatively poorer neighborhoods. But in developing countries, poorer neighborhoods can have dramatically lower levels of basic services. Consequently, a large number of urban residents in developing countries suffer to a greater or lesser extent from severe environmental health challenges associated with insufficient access to clean drinking water, inadequate sewerage facilities, and insufficient solid waste disposal. A major recent United Nations report on the state of water and sanitation in the world's cities found that water distribution systems in many cities in the developing world are inadequate, typically serving the city's upper- and middle-class neighborhoods but not rapidly expanding settlements on the urban fringe. Furthermore, the current data on the provision of water and sanitation in urban areas is very weak and the true situation is actually far worse than most international statistics suggest [20]. The large projected increases in the numbers of urban residents in the developing world over the next 20–30 years implies that municipal authorities responsible for these sectors face very serious challenges in the years ahead. In many cities, the scarcity of public water supplies forces many low-income urban residents to use other water sources such as private water vendors who charge many times more than the local public rate. Consequently, people in slums often must pay much more for lower quality water than other urban residents [21]. Improving public sanitation is another major urban environmental challenge that needs to be immediately addressed in virtually all cities in the developing world. Failure to collect garbage as well as inadequate waste management and recycling policies and practices mean that cities are being inundated in their own waste. In African cities, waste management has been described as ‘a monster that has aborted most efforts made by city authorities, state and federal governments and professionals alike’ [22]. As is the case of the water supply distribution network, sewerage systems are far better at meeting the needs of upper- and middle-class neighborhoods than they are of servicing poorer neighborhoods, particularly unregulated neighborhoods on the urban periphery. A major environmental crisis is looming large as many developing countries as cities discharge ever increasing amounts of waste into the air or into freshwater bodies, threatening water quality and aquatic ecosystems. The extent that urban growth affects the local ecosystem can be controlled to some extent by high quality land management. Land is an essential ingredient in all urban growth, yet in most cities there have been virtually no effective measures to control land development. Although many cities have formulated master plans at some time or another that included guidelines on land development and the future direction of urban growth, rarely, if ever, have these plans been realized. Reasons for this include poor urban governance, poor critical assumptions-urban population projections underpinning these plans have often been extremely weak-and the inability of plans to be adjusted and refined in the light of changing conditions, such as the invasion and settling of unused public space. Devising equitable land development policies remains one of the largest challenges facing planners and policy makers in many cities in the developing world. Congestion in many large cities can also be extremely severe and air pollution is now a serious environmental concern in many cities. Concentrations of carbon monoxide, lead, and suspended particulate matter in many large cities greatly exceed World Health Organization guidelines. Among the greatest environmental health concerns are exposure to fine particulate matter and to lead which contributes to learning disability in young children. A popular response to urban transportation congestion problems has been government investment in large-scale public transportation systems such as underground or overland metro systems. Less attention has been devoted to expanding and improving public bus networks, which tend to be overcrowded and poorly maintained. In many cities, private mini-bus companies have filled a hole in the market by providing low-cost urban transportation where standard bus routes have proved insufficient. Conclusion Around the world, especially in Africa and Asia, cities are expanding rapidly. For the majority of urban dwellers, especially the poor, finding potable water supply, affordable shelter, accessible and secure urban land for agriculture to ensure food security, securing gainful employment and improvement in health facilities would continue to remain a priority. Since restrictive urban growth policies, especially population distribution designed to reduce the rate of rural-urban migration appear to have had limited success in many developing countries, policies must be directed at transforming the rural economy in order to slow the rate of urban sprawl. Comprehensive land use planning and revision of planning standards and administrative procedures would, go a long way to, reduce many of the problems that face urban populations in the developing areas, especially Africa. A Vision for Healthy Urbanization in the 21st Century: Challenges and Opportunities for China Dr Henk Bekedam WHO Representative, China Healthy urbanization: a framework for action in China China's Scientific Concept of Development rightly considers urbanization not only as means to further boost economic growth, but also as means to improve the life of people in China. In this context, given the health risks associated with urbanization, it is very appropriate and necessary to put people's health squarely on the urbanization agenda. Putting people's health on the urbanization agenda is, however, a very complex task that requires concerted government policy actions across many sectors. Specifically, in order to alleviate the impact of urbanization on people's health, government policies need to promote quality of urban life, environmental sustainability, health awareness, equitable access to basic health-related services and accountability of local government officials and people working in private enterprises for people's health. A. Quality of urban life International experience suggests that to promote quality of urban life, government particularly needs to act in three related areas: First, design and develop urban peripheries for people as well as for economic activity. This includes, moving industries out of the city centers and synchronizing the emergence of jobs in industries with housing and public infrastructure/services in urban peripheries. Second, design and develop user-friendly transport network. In this context, it is crucial to support public transport network and space for bicyclists and pedestrians, and thus reduce the necessity and advantages of relying on own car. Third, provide suitable space for physical activities and recreation. Cultivating green areas and â€Å"escape zones† in urban centers and peripheries encourages people to stay fit and healthy. B. Environmental sustainability To promote environmental sustainability in urban development, government needs to enforce strict measures toward environmental protection and support environment-friendly investments. Specifically, it is a crucial role for the government to enforce environmental standards, and invest into systems and projects improving the use of energy and energy conservation. In particular, the government needs to establish adequate pricing mechanisms for utilities to end the wasteful use of energy and water that is associated with blanket price subsidies. Similarly, the government needs to enforce energy-efficient construction practices. Critical are also investments into municipal waste management and environment-friendly technologies. C. Health awareness As urbanization is changing people's lifestyles, promoting health awareness is critical. The government particularly needs to act on two accounts. First, disseminating health information and promoting healthy lifestyles. Easy access to information about nutrition, healthy habits, and health risks can positively affect people's behavior. To be effective, information dissemination needs to be complemented with active policies to support early child development, and sports and healthy habits in schools; and to nurture the positive image of healthy lifestyles. For instance, cycling to work would be again a sign of advancement and not backwardness! Second, developing and enforcing adequate health-related regulations. This important task involves all relevant sectors. It involves the market. It involves developing system to manage people's safety: traffic safety, environmental safety, occupational safety, patient safety, food safety and making public places smoke free. Finally, it involves mechanisms toward quality and cost-control in the health system. D. Equitable access to essential health services The possible negative health effects of urbanization underline the importance of enabling all people to have access to essential health services. In this context, it would be appropriate for government to make a package of basic health services accessible to all people in urban areas, urban peripheries and rural areas (residents and floating population alike). This package of basic health services needs to cover public health functions and services – including the prevention of chronic diseases – and essential clinical services. To finance equitable access to basic health, the government will need to ensure full funding for the basic package of health services – through health insurance, medical financial assistance schemes and its own budget. E. Accountability for people's health In order to align the performance of local governments, public sector enterprises and agencies and private sector entities with the agenda of healthy urbanization, government needs to establish clear accountability for people's health. In both the public and private sectors, agencies and enterprises need to bear responsibility for the health effects of their policies and actions. With respect to health services, health providers and local governments need to be accountable for ensuring equitable access, acceptable quality, safety, and fair price.

In many cities, private mini-bus companies have filled a hole in the market by providing low-cost urban transportation where standard bus routes have proved insufficient. Causes of urbanisation Urbanization and city growth are caused by a number of different factors including rural–urban migration, natural population increase, and annexation. Because rates of natural increase are generally slightly lower in urban than in rural areas, the principal reasons for rising levels of rbanization are rural–urban migration, the geographic expansion of urban areas through annexations, and the transformation and reclassification of rural villages into small urban settlements. The expansion of the metropolitan periphery can be caused both by the arrival of new migrants and by the sub-urbanization of the middle class out of the central city. The relative importance of each of these various causes of urbanization and suburbanization varies both within and between regions and countries. As stated above, over the next 30 years, population growth in general and urban population growth in particular is expected to be particularly rapid in the developing world, averaging 2. 3 per cent per year during 2000–2030. Although much of the popular rhetoric on urbanization has left the impression that cities are currently growing too fast and that growth should be limited or somehow diverted, it is important not to lose sight of the fact that, for the most part, there is an economic logic to the pattern of urbanization [14]. In most cases, high growth rates are an indicator of success rather than failure and most of the world's largest cities are located in countries with the world's largest economies. Many cities in Pacific Asia, for example, have experienced dramatic economic growth, reflecting the fact that the region is completely integrated into the new global economy. Cities on the forefront of global restructuring such as Hong Kong, Singapore, Seoul, and Taipei have enjoyed unprecedented growth rates of more than 10 percent per annum throughout the 1970s and early 1980s. All now rank among the top trading cities in the world and in fact, the level of gross national product (GNP) per capita in Hong Kong and Singapore exceeds that of many European countries. This extremely general descriptive of urban trends and projections naturally masks considerable regional diversity. There are enormous differences in the pattern of urbanization between regions and even greater variation in the level and speed with which individual countries or indeed individual cities within regions are growing.

Inventing A Writing Technology Essay examples - 1511 Words

Inventing A Writing Technology According to Walter Ong, an influential scholar of the relationship between technology and media, Literacy is imperious. It tends to arrogate to itself supreme power by taking itself as normative for human expression and thought. This is particularly true in high-technology cultures, which are built on literacy of necessity and which encourage the impression that literacy is an always to be expected and even natural state of affairs (316). Ong would probably agree that literacy is so embedded in our current technological culture that it has become part of the standard of living, a necessary requirement for functioning in this highly professionalized world. However, the point of Ong’s prior statement†¦show more content†¦Portability was described as the extent to which the text could be moved or carried. Nature referred to the extent to which the materials used in creating the text and/or writing surface were found in nature and not manufactured or highly processed. Du ring this experiment, I tried to consider what completely natural materials I could find. I resorted to using materials found in my backyard including rocks, dirt, sand, sticks, grass, and leaves. The permanence criterion of the assignment narrowed my choices by eliminating writing in the dirt, sand, or mud or with grass or leaves.
