Cognitive psychology on driving and phone usage

Cognitive psychology on driving and phone usage Introduction Some people claim that multitasking is an inevitable part of a fast-changing world. They believe that the current workplace is full of interruptions that must be accommodated. It is almost impossible for them to focus on one task uninterruptedly.Advertising We will write a custom essay sample on Cognitive psychology on driving and phone usage specifically for you for only $16.05 $11/page Learn More This is why many end up using their phones when driving. However, research shows that making phone calls can reduce a driver’s ability to perform tasks well because of the cognitive challenges involved. Multitasking versus performing a single task Cognitive skills are those mental skills that facilitate learning. One of these skills includes attention, which can be selective, divided or sustained. Multitasking is recognized as divided attention because it involves retaining and attending to two or more things. People do not ‘multitaskâ₠¬â„¢ per say; they merely switch from one task to another at very quick rates. When multitasking, individuals find it difficult to give tasks adequate attention and this leads to superficial processing. As one carries out a certain activity, one is likely to develop attention based inertia, which makes it very difficult to distract such a person. Multitasking disrupts this state of inertia and thus minimizes a person’s ability to perform tasks well (Frith et al., 2001). Cell-phone use requires cognitive skills because it is not an automated task; additionally, the same thing can be said about driving. These skills become automatic when practiced continually. For example, one can typewrite or play instruments with relative ease after doing so for a long time. This means that active processing may no longer be necessary. However, safe driving involves continuous learning and so does telephone use so these activities cannot be automated. For this reason, it is quite difficult to multitask when the activities involved are driving and talking on the phone (Redelmeier Tibshirani, 1997). Different types of talking Talking to passengers differs from talking on the phone because the passengers can pin point threats on the road. Passengers are likely to keep quiet when the driver is in the middle of a heavy traffic jam or when he or she is driving in hazardous conditions. Consequently, such passengers make driving safer.Advertising Looking for essay on psychology? Let's see if we can help you!

Hands free calling can reduce this problem by giving a driver freedom to use both hands. However it would still not address the root cause of the problem, which is related to the processing of information from multiple sources. The mind would still be involved in receiving and processing information from the telephone conversation as well as the road. Eventually, this would lead to dangerous repercussions such as swerving or crushing. Researchers have shown that most television viewers cannot process information effectively when watching two TC sets (Frith et al., 2001). The same thing applies to people who try to listen to two conversations at the same time. People will not remember most of the things they see or hear when this information comes to them simultaneously, because the brain’s cortex cannot effectively distinguish between relevant and irrelevant distractions. A conventional phone call is not different from a hands-free phone call because both distract the mind with new audio information. The brain focuses more on the phone conversation than the visual information from the highway because the latter information does not change as fast as the conversation does. This also happens because word s disappear after they are spoken so the mind would want to capture them before they fade away. As a result, drivers are likely to ignore certain visual cues on the road and this could be unsafe. Driving is a complex task which requires one to react to incoming information very quickly. Sometimes a pedestrian may cross the road unexpectedly or another car may get onto the wrong lane; these changes require frequent and rapid responses. One cannot respond promptly when one’s attention is focused on a phone conversation (Anderson, 2010). Text messaging when driving Text messaging is by far the most complicated of all phone related tasks. It requires a great deal of visual scanning, decision making, information processing and attention. A text message involves greater visual scanning than a phone call because a sender needs to look at the message he or she is creating, and that would take his or her eyes off the road.Advertising We will write a custom essay sample on Cogn itive psychology on driving and phone usage specifically for you for only $16.05 $11/page Learn More One also needs to make decisions on the kinds of words to use. This would be much harder because it involves the use of literacy skills, which are not required in phone conversations. Drivers would find information processing and concentration to be more difficult when text messaging than when talking on the phone. They need to ensure that they divide their attention between the road and the phone as they text. Some may miss visual cues when composing the message. All these additional task demands make text messaging more dangerous than talking on the phone. Conclusion Driving and talking on the phone simultaneously can be dangerous because both activities require cognitive skills. The brain focuses on the phone call at the expense of the most important task which is driving. One’s reaction time is severely impeded and this could be very hazardous. References Anderson, J.

The sandwich generation Research Paper Example | Topics and Well Written Essays - 1000 words

The sandwich generation - Research Paper Example This research paper aims to state the social, psychological and economic problems that the sandwich generation usually faces during this phase of life, and how their actions can affect the rest of the two generations. In order to state the best and the most accurate conclusion, a few examples of actual sandwich generation couples are included as well. The Sandwich Generation Sandwich Generation (Zal, 2001) is the generation stuck between two generations who are supposed to take care and give support to the younger generation (their children) and the older generation (their parents) at the same time. It is likely to suffer from a number of various psychological, social and economic problems are they do their job of prioritizing one of the generations over the other on different instances. The American Census of 2002 calculated that around 80-90 percent households in America provided assistance to aging parents, young children, disabled adult children and other relatives. The sandwich generations at most of the instances provided spiritual, emotional, physical, legal and spiritual support to the dependent generations. The role of the sandwich generations in these families is very demanding, stressful and mentally straining, as they are most likely to suffer from financial and emotional insecurities (Roots, 1998). According to Carol Abaya (Funnel et al, 2008), there are three different kinds of sandwich generations in various families in general. First kind of the sandwich generation, known as the Traditional Sandwich Generation, takes care of their aging parents and young children at the same time. The second kind, known as the Club Sandwich Generation (Funnel et al, 2008), is of two kinds; one takes care of their aging parents, adult children and grandchildren, this group is likely to be in their 50s or 60s, the second group is likely to be of people in their ‘30s or 40s, providing support for their young children, aging parents and grandparents’ (F unnel et al, 2008). In addition, the third kind is the one known as, Open Faced, this group, as describes by Abaya, consists of anyone else who takes part in care of elderly (Funnel et al, 2008). Younger Generation and the Sandwich Generation In a household, the younger generation is likely to be the most psychologically vulnerable to any sort of economic and social variables. As the children are likely to be in the initial socializing phase of their lives, whatever they experience is likely to create strong ideas and perceptions for them in return. Therefore, while being in this phase of life, effective communication and proper socialization is essential to ensure that the children are learning the best values and ideas, which they are likely to internalize for a lifetime. Nevertheless, in a multi-generational family, where the time and resources have to be divided amongst two different generations, the younger generations are likely to receive less than what they actually deserve. According to the research carried out by Sharon Hamill in 1994, on multi-generational families and their impacts on children, the results stated that the children in such families are likely to suffer from problems relating to ineffective communication and incomplete socialization. This caused the children to suffer from psychological problems and most of them ended up taking part in deviant and immoral activities like; being disrespectful to their parents, taking drugs, and participating in petty crimes like

Altria's Commitment to the Environment Essay Example | Topics and Well Written Essays - 750 words

Altria's Commitment to the Environment - Essay Example It wants to switch consumers' attention from the company for being solely a tobacco and alcohol company and show that it has serious environmental concerns so it pursues actions friendly to human beings. It would have been useless if these concerns were only part of a public relations plan and were not implemented in reality. People, nowadays, have become more environmentally conscious so it is in the best interest of a company to show that it respects the environment and it does not challenge the various environmental groups. Altria has to show that it wants to protect people's health and the best way to show it is by respecting the environment. No, the commitment will not offset the environmental issues with the tobacco company, at least not in the short - run. Each decision of the company made public will have an impact on its various stakeholders. So, a public relations campaign as this one will not bring the desired results if the rest of company decisions and strategy show the opposite. Even if the company decisions are in accordance with the environmental issues, still a negative perception of the image requires a lot of time in order to be changed into a positive one. Altria needs to be sincere with its customers and although it implements its environmental actions it needs to adapt its strategy as a company and become really concerned for consumer's health so this requires a strategic change from the tobacco business and diversify its product portfolio accordingly.

A Tale of Two Cities: Minor Characters Essay -- essays research papers

A Tale of Two Cities: Roles of Minor Characters Every story in the history of literature has one or more characters that are not as significant as other characters. Although these characters aren’t as important, they serve to advance the plot or are symbolically important. There are definitely numerous depictions of these characters in A Tale of Two Cities, by Charles Dickens. Two examples are Lucie Manette Darnay and Miss Pross. Both of these flat characters are important in the development of the story. Lucie Manette Darnay played an important and symbolic role in the novel. Dickens described her as â€Å"the golden thread† of the novel, weaving its good throughout the plot. Along with her good nature, she was also young and attractive. Dickens described her as having: †¦a short, slight, pretty figure, a quantity of golden hair, and a pair of blue eyes†¦and a forehead with a singular capacity†¦of lifting and knitting itself into an expression that was not quite one of perplexity, or wonder, or alarm, or merely of a bright fixed attention, though it included all the four expressions. (Dickens 17) Dickens created Lucie to be an ideal rather than a real woman. She represented all that is good in humanity—innocence, kindness, faith, and hope—and she served as a touchstone for other characters to find those qualities within themselves. Lucie is a loving and devoted wife to Charles Darnay. After Darnay’s death sentence she tells him: We shall not be separated long. I feel that this ...

Disaster Response and Relief

If being provided with a list from the Department of Homeland Securities of potential risk factors I would first look at these key issues and ways that I could improve the city’s chances of survival in a terrorist attack. I would look at the issues that were involved with these issues. My personal choice for order of dealing with the issues would be done so by my deciding which issues were more crucial and which ones needed to be dealt with first.With the list that was provided the order for these issues to be dealt with would take place in a specific order in order to promote the best chances of security and safety for all of the citizens involved. The first thing that would be done is that the airways would be secured and all incoming and outgoing air traffic would be stopped for some time. The next thing to do would be to secure waterways. This would include making sure that there were security efforts involved in protecting the city’s water sources as well.This woul d include the stopping of all water traffic and the security of the different ports and waterways that are surrounding the city. Next transport would be secured and stopped in order to allow for a more smooth evacuation of the city if necessary. This would mean that there need to be an exit strategy plan in the disaster plan that is on location at the town hall and other area disaster planning sites like the American Red Cross. All areas that produced power would be secured by as many forces as could be spared as well as trained disaster volunteers.This would be done so in order to help reduce the chances of harmful chemicals or toxins being released into the air in these areas. All food sources would be secured and there would be limited access to these sources in order to reduce the likelihood of contamination. During the beginning phases of this plan there would be specialists that would be involved in securing the computer systems and making sure that there was no one who was ab le to hack into important information. This would be handled at the same time as some of the other issues just by different specialists.There would be many different agencies that would be contacted. The first agencies to be contacted would be local law enforcement and area military. These would be first initiated in order to work on the security and safety of the city. The next agencies to be contacted would be those that are listed in the disaster plan including the local chapters of the American Red Cross, ESDA, and any other agency that has quick access to high volumes of volunteers. Schools and churches would be looked at as possible places for there to be shelters and food banks would be contacted as part of the process of having food and other goods.Other places that would be contacted are local grocery stores and other discount stores that would have access to high quantity of needed supplies. This would be done in partial efforts on putting limits on what each person could buy or have in order to ensure that supplies lasted for the most people possible. There would be limits placed on needed goods to ensure that all citizens could have some of them. The potential list of areas of vulnerability would need to be dealt with on a level where they were noted in the city’s Emergency Management Plan.Each of these issues would need to be discussed and there would need to be a plan for the emergency situation and how these issues would be dealt with. Whether or not the Incident Command System would need to be changed would depend on what was currently in place and what was needed. Basically if they were capable of addressing and dealing with all of the issues then there would not need to be any changes. However if they were not capable of this then there would need to be changes in order to ensure that they were capable.

Can you read my mind Essay

How do you know what you know? Can you figure out how you acquire language when you were still a child? How do you concentrate on reading this paper despite all the stimuli surrounding you? What do you think goes on your mind right now? These are just a few of the questions that cognitive psychology can answer with accuracy. Cognitive psychology is a branch of psychology that deals with how people think, perceive, remember and learn (â€Å"How people learn,† 2007). In the past, behavioral scientists explained certain phenomena by simply observing, then measuring and manipulating variables (â€Å"Albert Bandura,† 2006). Contrary to behaviorism, cognitive psychology explains the mental processes that take place when a person reacts mentally to various stimuli. These mental processes vary from person to person because each has his own schema of events. Schema, which is a term first used by Jean Piaget in 1926, refers to the set of well-defined concepts which a person already has in mind. These concepts may be â€Å"processed† through assimilation (â€Å"John Piaget,† 2006). For instance, a young child who is exposed only to `fork and spoon’ when eating will not recognize chopsticks as tools for eating as well. If you hand that child a pair of chopsticks, he or she won’t use it in picking up food to put on his or her mouth. It’s because that child doesn’t have a concept of chopsticks yet. However, after being exposed to his or her mom using chopsticks, the child will learn that those items can also be used in picking up food to bring to the mouth. That kind of learning is called assimilation which gives way to a new set of schema for the child. Cognitive development among children is just one aspect of cognitive psychology. This branch of learning may also be applied in more recent concerns. For example, teachers and learners are interested in finding out how people process two or more information at the same time. Interestingly, Piolat, Olive, & Kellogg (2005) conducted a study to know how multi-tasked people record notes while they try to comprehend new information from speakers. They found out through their research that â€Å"note taking demands more effort than reading or learning. However, â€Å"it requires less effort than the creative written composition of an original text† (p. 291). A working knowledge on how people think, perceive and learn is important in making predictions, making adjustments, and formulating policies that could aid the people in their day-to-day mental discourses. In one article, Jaroff (1993) told a story of a girl whose life became troubled after meeting with a psychiatrist who made her believe through â€Å"recovery† therapy that she was abused by her own father when she was a young child. Using her knowledge on cognitive psychology, particularly pertaining to how people retrieve memory, she discovered that what she ended up confessing to the psychiatrist was false (â€Å"Lies of the Mind†). This means that an understanding of this branch of knowledge allows people to be more conscious of how they deal with the world. Cognitive psychology is more than just a branch of knowledge. It is a portal leading to your most used but most strange place in this world – that is your mind. You think every day, you learn new things every minute but you forget to understand how all these thoughts are accommodated in your brains, in your minds. In conclusion, cognitive psychology offers explanation to the mental events that take place in a person. These mental activities can explain the past, and the present, to give way to a better future. After all your life depends not exactly on your environment but on how thoughts are processed in your head.

Jean Piaget theory on child development Essays

Jean Piaget theory on child development Essays Jean Piaget theory on child development Essay Jean Piaget theory on child development Essay Jean Piaget theory on child development Piaget was a psychologist who developed interest in children’s intellect. He worked with Alfred Binet and later came up with a theory on cognitive development of children. This theory explains cognitive child development. This type of development entails changes in cognition processes and capabilities. According to this theorist’s view, early development in cognition includes processes founded on actions. Later on, it advances to changes in mental activities. Piaget states that adults are not intelligent than children. The difference is children have a different way of thinking. This observation amazed Albert Einstein because people would not see its simplicity. Piaget came up with some concepts of this theory. Some of them are schemas, which is the description of mental and physical activities included in knowledge and understanding. The schema contains knowledge and its method of acquisition. When children encounter experiences, the new knowledge is added, or schemas change. For instance, if a child only sees a kitten he or she will tend to think all cats resemble that kitten. After he or she sees a cat, her perception will change.

History of Naturalization Requirements in the U.S.

History of Naturalization Requirements in the U.S. Naturalization is the process of gaining United States citizenship. Becoming an American citizen is the ultimate goal for many immigrants, but very few people are aware that the requirements for naturalization have been over 200 years in the making. Legislative History of Naturalization Before applying for naturalization, most immigrants must have spent 5 years as a permanent resident in the United States. How did we come up with the 5-year rule? The answer is found in the legislative history of immigration to the U.S. Naturalization requirements are set out in the Immigration and Nationality Act (INA), the basic body of immigration law. Before the INA was created in 1952, a variety of statutes governed immigration law. Lets take a look at the major changes to naturalization requirements. Before the Act of March 26, 1790, naturalization was under the control of the individual states. This first federal activity established a uniform rule for naturalization by setting the residence requirement at 2 years.The Act of January 29, 1795, repealed the 1790 act and raised the residency requirement to 5 years. It also required, for the first time, a declaration of intention to seek citizenship at least 3 years before naturalization.Along came the Naturalization Act of June 18, 1798 - a time when political tensions were running high and there was an increased desire to guard the nation. The residence requirement for naturalization was raised from 5 years to 14 years.Four years later, Congress passed the Naturalization Act of April 14, 1802, which reduced the residence period for naturalization from 14 years back to 5 years.The Act of May 26, 1824, made it easier for the naturalization of certain aliens who had entered the U.S. as minors, by setting a 2-year instead of a 3-year interval between the declaration of intention and admission to citizenship. The Act of May 11, 1922, was an extension of a 1921 Act and included an amendment that changed the residency requirement in a Western Hemisphere country from 1 year to the current requirement of 5 years.Noncitizens who had served honorably in the U.S. armed forces during the Vietnam conflict or in other periods of military hostilities were recognized in the Act of October 24, 1968. This act amended the Immigration and Nationality Act of 1952, providing an expedited naturalization process for these military members.The 2-year continuous U.S. residence requirement was done away with in the Act of October 5, 1978.A major overhaul of immigration law occurred with the Immigration Act of November 29, 1990. In it, state residency requirements were reduced to the current requirement of 3 months. Naturalization Requirements Today Todays general naturalization requirements state that you must have 5 years as a lawful permanent resident in the U.S. prior to filing, with no single absence from the U.S. of more than 1 year. In addition, you must have been physically present in the U.S. for at least 30 months out of the previous 5 years and resided within a state or district for at least 3 months. It is important to note that there are exceptions to the 5-year rule for certain people. These include: spouses of U.S. citizens; employees of the U.S. Government (including the U.S. Armed Forces); American research institutes recognized by the Attorney General; recognized U.S. religious organizations; U.S. research institutions; an American firm engaged in the development of foreign trade and commerce of the U.S.; and certain public international organizations involving the U.S. USCIS has special help available for naturalization candidates with disabilities and the government makes some exceptions on requirements for elderly people.

The Occupation of France through the eyes of Irne Nmirovsky in Suite Dissertation

The Occupation of France through the eyes of Irne Nmirovsky in Suite Franaise - Dissertation Example Irene Nemirovsky’s book, Suite francaise, written in two sections, ‘Storm in June’ and ‘Dolce,’ starts with an air raid siren going off in the early morning hours before sunrise, yet people are still not so anxious as of yet that they feel they must run away (Nemirovsky 3). (Indeed, many went back to sleep for just a bit longer once the sirens stopped.) Yet, in the distance, there was the sound of heavy guns firing, some of it coming closer and closer. Finally, the sun comes up and the shelling stops. There is a peaceful, yet uncertain pause in the craziness. Something is just waiting around the corner, yet to be seen (Nemirovsky 4). In this glimpse of the novel, we are made aware of the fact that people just barely understand what is happening to them and really cannot believe any rumours and reports they have been getting about the German forces moving their way or that things could be that bad (Nemirovsky 5). As is so often seen, when changes are m ade within a society coming from the outside, people do not want to believe that they are in danger. It is a case of pulling the night mask over one’s eyes so as to wake up and find that everything is alright again and back to normal. In fact, in the novel, this is the beginning of the end of whatever normal they had in their lives. It is a down-hill spiral from that point onwards. Suite francaise presents a number of people in all their diverse personalities, set in a time that will turn to a future of unimaginable horror. At the period of time that Irene writes this book, many of the horrors committed by the Nazis are still unknown definitively to most outside of the European theatre of war, but there had been rumours. Indeed, Irene may have suspected or heard through the rumour mill about what was truly happening to the Jews, of which she was one. Most, however, did not want to believe that such things were happening and it would not be until the end of WWII that the truth of the genocide of the Jewish people and other ‘undesirables’ would be fully revealed and even then, some would not believe it did take place. The background in the novel therefore provides a scenario which is perceived by the characters as they would have known their own world for that time when people did not know that much about what was happening, only that there was a war going on. In our current age of the Internet and social media of modern times, information and news travel around the world in a flash, within seconds or even milliseconds. At the beginning of WWII, however, information would have taken far more time to be dispersed to the general population in varying levels of electronic access by radio. Under the German occupation, much of that news would have been restricted and also turned to propaganda before being released to the general public. Therefore, her characters also react accordingly to what they know at that point in time of occurring history, n ot what we know in our perspective of that history many decades later. Regarding these two points of view, we see what is coming for these people but we can only shout silently to deaf ears of the characters in this story because they are not there yet in that level of knowledge. The time we know of through historical documentation, has not yet occurred for them or if it is occurring, they do not know of it yet, while we, who are in the future, already know where the story is headed, at least

Parkinsonism and other Extrapyramidal Diseases Essay

Parkinsonism and other Extrapyramidal Diseases - Essay Example In essence, I did the best I could with what I was provided. The normal functions of the human basal ganglia have largely been deduced from the study of functional problems associated with destructive or irritative lesions. To a large degree, the deficits are in motor function and, therefore, the extrapyramidal system and basal ganglia have been associated with movement disorders. Important interconnections of the basal ganglia are the nigrostriatal pathway, and the ansa and fasciculus lenticularis, and the fasciculus thalamicus, which interconnect the globus pallidus and the ventral lateral and ventral anterior (VL-VA) nuclei of the thalamusand the VL-VA thalamocortical fibers, the subthalamopallidal pathway, striatopallidal fibers, and cerebellothalamic interconnections Parkinson's disease, first described by James Parkinson in 1817, is one of the most important disabling illnesses of later life. It is estimated to affect 1% of 70-year-olds, but is also seen in younger people, with 10% of cases occurring before the age of 50. Parkinson's disease is one of the most common neurodegenerative diseases, but estimating its incidence and prevalence is problematic, since there is no 'in-life' marker for idiopathic Parkinson's disease; estimates of the annual incidence of Parkinson's disease are in the range of 4 to 20 per 100000 individuals. A widely accepted figure for the prevalence of Parkinson's disease is approximately 200 per 100,000 populations. In the UK, there are approximately 120,000 to 130,000 diagnosed cases, but there may be many more that remain undiagnosed. In the USA, it is estimated that between 750,000 and 1.5 million people have the disease. ( Ref) Age, Sex, and Ethnicity Both the incidence and prevalence of Parkinson's disease increase with age, and the prevalence may be as high as 1 in 50 for patients over the age of 80 years. Men are 1.5 times more likely than women to develop the condition are. Hospital-based studies have suggested that Parkinson's disease is less common in the black population. Pathology The main pathological feature of Parkinson's disease is the degeneration of neuromelanin-containing neurons in the pars compacta of the substantia nigra. Examination with the naked eye reveals pallor of this area, which is confirmed microscopically by a marked decrease in the number of neuromelanin-containing cells and the presence of Lewy bodies in the remaining nigral neurons. Degeneration of pigmented neurons in the brainstem is not limited to the nigra but extends to the locus ceruleus and the dorsal motor nucleus of the vagus. Neuronal Degeneration The cause of neuronal degeneration in Parkinson's disease is unknown. The susceptible neurons are located in astroglial-poor regions such as the ventral tier. Glia may offer neuroprotection by providing neurotrophic factors that prevent cell death. Several hypotheses for neuronal degeneration have been proposed, including: oxidative stress, induced by dopamine metabolism or other factors defective mitochondrial energy metabolism excitotoxin- and xenobiotic-related cell death programmed cell death (apoptosis) to the medial
