Manichism In Economics Essays - Economic Theories,
Manichism In Economics The Manichaean character of economics. Charles Kindleberger. Abstract: Economics is said to have adopted a certain degree of dualism. None of its tenets have been absolute in terms of social effectiveness. To survive in an economic system, rules must be enforced to ensure the peace. There are times when pluralism is good for a society as a way recognizing social differences. However, there are times, such as war, when the rule of a central authority is preferred. Laws in economics are hardly permanent since such regulations are enacted and enforced only when the need arises. Full Text: COPYRIGHT 1999 M.E. Sharpe, Inc. Are there any absolute answers in economics? This international trade economist and economic historian has his doubts. The answer to most questions is "It depends." Manichaeus, as we all know from the Oxford dictionary; was a Persian philosopher of the third century A.D., whose system held some sway throughout the Roman empire and Asia until the fifth century (with some elements lasting to the thirteenth). He believed in dualism, the coexistence of good and evil, with Satan coequal with God. I suggest that economics has a heavy dose of dualism, though I hesitate to characterize views that differ from mine as evil or satanic. In the first edition of Economics: An Introductory Analysis the only one I read when I was teaching the introductory course - Paul Samuelson wrote that when one is offered a choice, it is not legitimate to say "both." I hesitate to differ from my esteemed colleague, but "both" is often a correct answer, as occasionally is "neither." Is one supposed to believe in Say's law that supply creates its own demand, or Keynes's law that demand creates the needed supply? In the course of a long academic life, I have developed Kindleberger's law of alternatives, based on historical examples. Often after extended policy debate, the powers that be end up doing both. In 1931 Keynes recommended tariffs, others devaluation or depreciation. Outcome: both. During World War II there was a vigorous Allied debate as to how best to push back German railheads from the Normandy beaches, whether by bombing marshaling yards, as the British called them, or bridges. Answer again: both. Nor did questioning a German prisoner of war, General des Transportwesen West, under Marshall von Runstedt, make clear which was better. American interrogators got the answer from Oberst (colonel) Hoffner they wanted - bridges - and the British theirs - marshaling yards. Robert Heilbroner has been a Classicist (Say's law?) and a Keynesian (Keynes's law?) and has been mildly infected with Marxism, but has never to my knowledge adopted the absolutist position of denying all truth to the polar opposite. In economic debates we have capitalism versus socialism; perfect markets with rational and informed suppliers and demanders versus market failure; monetarism versus Keynesianism; fundamentals (such as geography demography, technology, and perhaps history) versus institutions, path dependency; externalities, and occasional breakouts of herd behavior ending in financial crisis; free banking versus regulation and central banks; public choice versus markets (governments make mistakes but markets seldom do, and such mistakes as they rarely make are quickly corrected); centralization versus pluralism; rules versus decisions by authorities . . . One could go on. In international trade, which I taught before I learned the delight of historical economics, I was wont to say that the answer to every question in economics is, "It depends," and that it usually depended on the magnitude of the elasticities. President Truman sought one-armed economic advisers because of his unhappiness with the answer to his question "On the one hand, . . .; on the other hand, . . ." I have admiration approaching reverence for the thirty-third president of the United States, but I cannot endorse his pleas for an answer of "Yes," or perhaps "No," followed by a number. Let me illustrate this deeply philosophical or perhaps cowardly position with a few examples drawn from history. I skip capitalism versus socialism because most of us believe in the mixed economy, perhaps leaning slightly to one or the other, but in any case nowhere near the limits. Such, as I interpret it, is the Heilbroner take on Marxism since his infection at (by?) the New School. Centralization versus pluralism can be disposed of in two sentences, though I have a book of 100 pages on the issue: In quiet times, pluralism is better because it is more democratic. In crisis or on deep moral issues such as slavery or racism, some central authority is preferable. It is, however, difficult to

HumanitiesGrecoRoman Culture essays
HumanitiesGrecoRoman Culture essays Aristophanes was a "craft" comedy poet in the fourth century B.C. during the time of the Peloponnesian War. Aristophanes' usual style was to be too satirical, and suggesting the outlandish. He shows little mercy when mocking Socrates and his "new-fangled ideas" which were most likely designed to destroy the cohesiveness of society and lead to The most absurd and humorous of Aristophanes' comedies are those in which the main characters, the heroes of the story, are women. Smart One of the most famous of Aristophanes' comedies depicting powerfully effectual women is the Lysistrata, named after the female lead character of the play. It portrays Athenian Lysistrata and the women of Athens teaming up with the women of Sparta to force their husbands to end the To make the men agree to a peace treaty, the women seized the Acropolis, where Athens' financial reserves are kept, and prevented the men from squandering them further on the war. They then beat back an attack on their position by the old men who have remained in Athens while the younger men are out on campaign. When their husbands return from battle, the women refuse to have sex with them. This sex strike, which is portrayed in a series of (badly) exaggerated and blatant sexual innuendoes, finally convinces the men of Athens and Sparta to agree to a The Lysistrata shows women acting bravely and even aggressively against men who seem resolved on ruining the city-state by prolonging a pointless war and excessively expending reserves stored in the Acropolis. This in turn added to the destruction of their family life by staying away from home for long stretches while on military campaign. The men would come home when they could, sexually relieve themselves, and then leave again to continue a senseless war. The women challenge the masculine role model to preserve...

Human Genome Project Essay Example | Topics and Well Written Essays - 1000 words
Human Genome Project - Essay Example According to the essay "Human Genome Project" findings, the human genome comprises more than milliard of nucleotides, the elements, which form the structure of the genetic code of every human species. In 1990, Venter became a leader of his own private company ââ¬Å"Celera Genomicsâ⬠, which did it best to be the first in the genome decryption, it was competing with the federal program the ââ¬Å"Human Genome Projectâ⬠, which was getting its financing from the United States government. However, both sides acknowledged their draw in the year 2000 (Khoury et al, pp.17-18). After Dr. Venter has left the ââ¬Å"Celera Genomicsâ⬠, as he did not share the business strategy of the company, he uncovered the truth that more than half of the decrypted genes were his own. At present, he is the head of his own non-commercial scientific center in Rockville, Maryland. In addition, their last achievement was total decryption of Venter's genome. As a usual person, Dr. Venter has six mi lliard nucleotides, which form thousand of genes, subdivided into 46 chromosomes. The genes represent a manual that has the detailed description of the body function; they produce proteins that are responsible for nearly everything in our organism, i.e. for the height, or the eye color, the body shape, proportions, etc. The scientists from the Venterââ¬â¢s institute have a close approach to his full genome decryption. J. Craig Venter is planning to transform his genetic code in a form of a computer database. The D4 receptor in the Venter's genome shows us, that he has the risk to have a heart attack.

Computers Research Paper Example | Topics and Well Written Essays - 1500 words
Computers - Research Paper Example This further took a new dimension when the web 2.0 was introduced with offers like social networking sites, blogs, and other similar features which made it more interesting and hard to resist and avoid. The intensity of the usage and its presence in our daily life can be imagined by the fact that just a single website has as many as eighty million members on it. With time the progress made by computers was so enormous that they crept into different disciplines of life and today they are part of every mobile phone, every television set, every refrigerator and every screen that is out on the road and in the sports gymnasiums. Mid 80s: While the first twenty years were slow in progress with regard to computerââ¬â¢s development. The dominant force in those times was I.B.M and computers were quite large in size. The changes came in, in time when the black and white and colorless scheme was replaced by the colored screens. The command line interface (C.L.I) was replaced by Graphic User Interface (G.U.I) and it brought more interest in to it(Kumar, 51). Apple Computer Inc. (now Apple Inc) was the pioneer in this regard and introduced resulted in more interest attraction from the customers (O'Grady, 32). The next step in the overall journey was the reduction of sizes of computers. While at first the computers were not able to be handled by single user and mainframe computers were quite common which were only limited to organizational usage, they were soon replaced by the personal computers which resulted in one computer per home and one computer per room. However even this was to change and the change came in form of the monitors and display screens. The cathode ray tubes (C.R.T) were replaced by L.C.D (Liquid Crystal Displays) which... Moore rightly predicted change and increase in the number of computer electronic devices every eighteen to twenty months (Shuman, 10). Where we stand today can be the ground breaking foundation for what is to come ahead. What we consider mammoth in terms of the progress made by computers might well be the stepping stone towards more advanced technologies and with the progress so far made, it is promised to bring further revolution and change in the manner in which computers are being handled. The terabyte space which might seem large enough today might not be even sufficient to accommodate the requirements of future single hard disk drive. They have created a total new world of digital existence with lots of jobs on offer and many other activities which would not be possible otherwise. It is the true gift of 20th century that is bound to stay here for times to come.

My main research question for this paper was : How do Social networking services affect Korean international studentsââ¬â¢ adaptation to the U.S.? Literature Review Before SNS such as Facebook, launched by Mark Zuckerberg in February 2004, (Carlson, 2010, Par.1) became popular, most Korean international students used internet community services such as Cyworld Mini Home where people post pictures or write an open diary or email services to share his or her daily stories with family or friends living in the home country. However, internet community services are a sort of one-way communication tool, so people need to regularly stop by and log into the community homepages in order to read or leave a message to his or her friends. On the other hand, although email services are a two-way communication tool, it is not easy to contact everyone regularly while studying abroad. Actually, there was no way for Korean international students to maintain close relationship with home country friends and family after going abroad. Moreover, it is even more difficult for adult foreigners to make friends with host country students because each of them may have di fferent cultural background or interest and concerns (Malarcher, 2004). As a result, many Korean international students experience emotional isolation and suffer from high mental stress because of homesickness, new relationship with classmates and cultural differences. For example, I had a chance to study in Omaha, Nebraska for nine months after finishing mandatory military services in 2002. At that time, I was not able to make American friends except for a couple of roommates since I had no chance to meet them privately, but also could not keep in touch with my friends in my homeland, so I ... ...., and Twitter Inc. became public companies, people seem to regard SNS only as a profitable business model. However, the original characteristic of SNS linking people closely is still effective. From that point, I reviewed related literatures and compared them with what I observed during last 6 months at GWU. First, SNS cannot replace face-to face communication, so it has a limited effect to help international studentsââ¬â¢ adaption to the new environment. Second, since SNS makes international students feel comfortable, if colleges use them as an educational tool to draw active participation of international students, it could work. I conducted this research only based on literature reviews and observations. Therefore, for the following research, I would like to conduct a survey of Korean international students to know how they use SNS to enlarge their human networking.

Cognitive Approach to Psychology
Shane Galvin-061 AT-Applied Psychology Shane Galvin Class: 061/AT Applied Psychology Teacher: Carol Neenan Title: Psychological Perspective Word count: 3121 The Cognitive Approach to Psychology Contents Page 1 ââ¬â Contents Page 2 ââ¬â Introduction Page 3 ââ¬â History Page 4 ââ¬â Cognitive Psychology and Cognitive Science Page 6- Research methods i) iii) v) Reaction time Studies Eye Tracking Studies Psychophysics ii) iv) vi) Priming Studies Lateralisation Studies Single-Cell Studies Page 8 ââ¬â Memory Storage and Models Page 10 ââ¬â Therapeutic Applications Page 11 ââ¬â Evaluation Page 12 ââ¬â Bibliography Shane Galvin-061 AT-Applied Psychology The Cognitive Approach to Psychology What is Cognitive Psychology? Literally, ââ¬ËCognitionââ¬â¢ means knowing, but in the greater framework of Psychology, Cognition is thinking, perceiving information, understanding, construction and presentation of an answer to a question. Essentially, cognition is a ter m for the use of our mental processes. ââ¬Å"Cognitive Psychology is the study of higher mental processes such as attention, language use, memory, perception, problem solving, and thinking. â⬠(Gerrig & Zimbardo. 2002) Cognitive Psychology uses scientific methods and scrutiny to develop a deeper understanding of the human mind, rather than the brain, a methodology perhaps adapted from Behaviourism, in which modern Cognitive Psychology holds its roots. Yet, unlike behaviourism, which only focuses on observable behaviour, Cognitive Psychology is also concerned with internal mental states. 2 Shane Galvin-061 AT-Applied Psychology History In 1932, Behaviourist Edward Tolman published his book ââ¬Å"Purposive Behaviour in Animals and Menâ⬠In his works Tolman studied rats in a maze, in which food was placed at the end of the maze.In the initial phase of a test, the rat would not be hungry while first entering the maze; this would allow the rat to learn where the food would be and to associate a certain location with the prospect of food. Of course, being armed with such a primal survival instinct would influence the rat to learn and adapt quickly. The rat would move in the general direction of the food as opposed to a specific pathway and Tolman observed that the rats were able to use untrained routes towards the food.This meant that rats had an ability to learn, beyond mere survival instinct and presented a problem for radical behaviourism. Whether Tolman knew it or not, both he and his rats were laying down the groundwork for modern cognitive psychology. Tolman theorized that the animal had developed an image of its environment that it later used as a reference when finding its food. This is called a ââ¬Å"Cognitive Mapâ⬠i. e. , the rats showed use of their cognitive map by reaching a goal (food) from a number of different starting points.The rats had no instinctive information of the maze and no stimuli that would condition it to have knowledg e of the maze, in other words; the rats learned about their environment and stored the information. This helped to establish some basis for memory storage, learned behaviour and analytical methodology for Cognitive Psychology and would help Psychologists prepare for the ââ¬Å"Cognitive Revolutionâ⬠of the 1950ââ¬â¢s where Cognitive Psychology and its principle areas of research begin to become defined. 3 Shane Galvin-061 AT-Applied PsychologyThe Term ââ¬Å"Cognitive Psychologyâ⬠came into use in 1967 in the book Cognitive Psychology by Neisser. ââ¬Å"â⬠¦ the term cognition refers to all processes by which the sensory input is transformed , reduced, elaborated, stored, recovered and usedâ⬠¦ it is apparent that cognition is involved in everything a human being might possibly do; that every psychological phenomena is a cognitive phenomenaâ⬠(Neisser, 1967) Perhaps it was the invention of the computer that gave Cognitive Psychology the most credibility.For t he first time in history, mankind had something to which it could compare with the human brain or mind, and gave the cognitive approach its terminology. By being able to study a simpler artificial construct, psychologists now had the opportunity to learn more about cognitive processes. ââ¬Å"Cognitive psychology focuses on the way humans process information, looking at how we treat information that comes in to the person (what behaviorists would call stimuli), and how this treatment leads to responses. In other words, they are interested in the variables that mediate between stimulus/input and response/output. (McLeod, 2007) Cognitive Psychology and Cognitive Science Part of the effect that the cognitive revolution had on its approach is the amalgamation of techniques and ideologyââ¬â¢s from other distinct areas of research and study such as linguistics, computer science, developmental psychology and cognitive psychology. It seems as though it is a reaction to the ââ¬Ëstimulu s-responseââ¬â¢ methodology and mode of interpretation espoused by behavioural scientists. Noam Chomsky theorised that the brain had a centre for language acquisition that went beyond what could be explained by behavioural psychology.Jean Piaget had laid out stages of cognitive development that children go through which again could not be explained within the framework of Behaviourism. Computer scientists provided a new way of comparably examining the brain by using computer processing as a method to conceptualise brain processing. ââ¬Å"These scientists maintained their own distinct methodologiesâ⬠¦ but they held together and remained united in their interest in cognition and in their goal to bring the scientific study of these processes to light. This scientific collective became known as cognitive scienceâ⬠(Solso, et al. 2008) In modern times cognitive science relies on computer science, philosophy, psychology, neuroscience, linguistics and anthropology. Cognitive s cience is heavily influenced by computer science; in computer modelling it is possible to construct and test cognitive models, in the form of artificial intelligence (AI) which has leaked into popular use in the form of interactive technology such as video gaming. 4 Shane Galvin-061 AT-Applied Psychology But it is of particular benefit to psychologists because they can test certain, although limited, cognitive models and theories based on computer models.Cognitive Psychology uses a combination of techniques adapted from other areas of research in order to research its own theories, thus we have an intrinsic relationship between cognitive psychology and other methodologies as illustrated in Gardnerââ¬â¢s Hexagon. The diverse range of methodologies in the cognitive approach allows researchers and clinical psychologists to approach problems, issues and hypotheses from a multitude of different backgrounds and allow a wider range of scrutiny to verify their findings in keeping with sc ientific inquiry.Ultimately this allows the cognitive scientist/psychologist to create models of predictive capability that are reproducible which, in Psychology, allows for a greater understanding of the human mind and its mechanisms. 5 Shane Galvin-061 AT-Applied Psychology Research Methodââ¬â¢s The research methods of cognitive psychology observe and record how we take in information from the physical world, the response time of reactions and how we process this information to perceive it. ââ¬Å"The methodââ¬â¢s of cognitive psychology stem from those used by early German researchers studying memory, association and processes.These tools became a mainstay of experimental psychology. As cognitive psychology began to form and become interdisciplinary, methods from other research fields were borrowed and modified for use in the study of cognitive processes. Research methods are the tools by which we come to know and understand, as well as test ideas and develop new ones. â⠬ (Solso, et al. , 2008) i) Reaction Time Studies: Reaction time studies are used to study cognitive processes and seem to be a defining methodology in the cognitive approach.An example is Donderââ¬â¢s complication studies, in which a subjectââ¬â¢s response speed to a white light being turned on was recorded and compared to a yellow light being turned on. Researchers believed early on that the time difference between the two responses could have been attributed to additional processing that it took to differentiate the yellow from the white light. ââ¬Å"Reaction time studies fundamentally rely on the assumption that cognitive activity takes time and that one stage is completed before the other starts. â⬠(Solso, et al. , 2008) ii) Priming studies:Priming studies have been used by psychologists for quite some time. With the invention of computer technology, specifically brain imaging technology, priming studies are becoming more popular. ââ¬Å"In priming studies a stim ulus is briefly presented (a prime) and then, after a delay, a second stimulus is presented and a participant is asked to make some judgement regarding the second stimulus, such as, ââ¬Å"Is the second stimulus the ââ¬Ësameââ¬â¢ as the first? â⬠(Solso, et al. , 2008) There are two types of priming effects. The Semantic priming Effect and the Object priming effect.The Semantic priming effect is that by activating one item, the acceptability of the second item is enhanced. The Object priming effect is typically in two stages. The first stage is the presentation of an object. This is followed by an interval that may be as short as a millisecond or as long as several months. In the second stage an object similar to the first object is presented, it could be changed, degraded or rotated etc. The participantsââ¬â¢ accuracy in remembering the first object is then measured and sometimes the reaction time is measured as well. Tulving & Schacter, 1990) 6 Shane Galvin-061 AT-Ap plied Psychology iii) Eye-Tracking studies: A large portion of the brain is used for interpreting and processing visual sensory information. Researchers have developed techniques to track the movement of eyes in order to determine where a personââ¬â¢s eye is fixed which in particular helps to study people reading, what sentence they are looking at and where they look next. Eye-tracking studies have helped researchers to discover that people who have dyslexia have different eye movements to people who do not have dyslexia. v) Lateralisation Studies Lateralisation studies developed from the idea that the two sides of the brain are responsible for different cognitive functions, in an effort to localise functions within the brain, Broca and Wernickeââ¬â¢s areaââ¬â¢s ( centres that are responsible for speech and language) are located on one side of the brain, the left side, this implies that the brain has localised areaââ¬â¢s for different functions, these studies were partic ularly important in the area of memory study and studies of amnesiac patients, through the methodology used in lateralisation studies, i. e. riming type tests, and brain imaging we know that the hippocampus is responsible for memory, although there are two hippocampi. There are also more invasive techniques used in lateralisation studies using patients with extreme epilepsy undergoing preventative surgery whereby the corpus collosum, the fibreââ¬â¢s which connect the hemispheres of the brain, are cut. v) Psychophysics Psychophysics is the scientific study of the relationship between stimuli and the sensations and perceptions evoked by these stimuli. (Solso, et al. , 2008) Psychophysicists are interested in perceptual thresholds.For example in Weberââ¬â¢s study of perceptual thresholdââ¬â¢s he tested a personââ¬â¢s ability to detect weight. If a person was holding a weighted object, how much weight could be added before the person could detect and perceive the difference in weight. vi) Single-cell Studies Single-cell studies are typically conducted in animals as opposed to humans because of their invasive nature. Hubel & Wiesel, who were awarded a Nobel Prize for their 1959 research, mapped the visual cortex of cats. This research involved the opening of the skull of the subject.They had theorised that because single cells communicate with each other via electrical impulses then it would be possible to probe these single cells with a an extremely fine meter to measure the amount of electrical activity in a cell without damaging it, thereby allowing them to evaluate perceptual experience at a cellular level. Hubel & Wiesel basically restrained a cat , opened its skull, probed itââ¬â¢s brain and then showed the cat 7 Shane Galvin-061 AT-Applied Psychology moving images and kept probing until they could record the level of cellular electrical activity.This gave us an insight into how we visual perceive the world and the physical action that takes pl ace in the brain. (Solso, et al. , 2008) Memory, Storage and Models Cognitive Psychology is viewed as a pure science, its accepted theories on memory, for example, are based on laboratory experiments with demonstrable results as well as solid work in case studies. For example the Multi store Model (MSM) by Atkinson & Shiffrin (1968, 1971) cited by (McLeod, 2007) attempted to explain how information is transferred from Short Term Memory to Long Term Memory.This model views sensory memory, STM and LTM as ââ¬Å"permanent structural componentsâ⬠and suggests that memory is made up of a series of stores. MSM likens memory as information flowing through a system. Information is detected by the sense organs and enters the sensory memory. If attended to this information enters the short term memory. Information from the STM is transferred to the long-term memory only if that information is rehearsed. If rehearsal does not occur, then information is forgotten, lost from short term memo ry through the processes of displacement or decay. McLeod, 2007) This model has influenced the study and research of memory and is supported and informed by studies of retrograde and anterograde amnesia. The Working Model of Memory (Baddely & Hitch, 1974), shows that short term memory is more than one store and consists of different components. Similarly, in long term memory different kinds of memory such as addition/subtraction, how to play chess or what we did yesterday are not stored in one ââ¬Ëhard-driveââ¬â¢ type long term memory store. There are different types of memory, episodic (memory of events), procedural (memory of how to do 8 Shane Galvin-061 AT-Applied Psychology hings) and semantic (general knowledge). This model of memory espouses that rehearsal is the process whereby by we transfer information into Long term memory but that it is not necessary to rehearse in some cases. . We know, now, that the part of the brain that deals with memory is the hippocampus; it i s part of the limbic system and deals with short term memory and long term memory, as well as spatial functions, the hippocampus is shown in this diagram. As we can see, there are hippocampi; there is a hippocampus in both sides of the brain. The hippocampus is part of the cerebral cortex and is located in the medial temporal lobe.Damage to the hippocampus can result in a person being unable to store new memories and is quite devastating to a personââ¬â¢s quality of life. In the case of Clive Wearing, based on Baddely, 1990; Blakemore 1988 as cited in (Gross, 2010), who suffered from anterograde amnesia, we can see the effects of damage to the hippocampus, in this case caused by a rare brain infection caused by the cold sore virus (Herpes Simplex). Mr. Wearing lives almost as if he is frozen in time, constantly believing he has just woken from years of unconscious sleep. He retains developed skills, for example he was the chorus master of the London Sinfonietta.Unfortunately for Mr. Wearing his ability to recall memories from earlier in his life is extremely patchy, at best. Atkinson and Schiffrin regard the kind of memory Deficits displayed by Clive Wearing as ââ¬Ëperhaps the single most convincing demonstration of a dichotomy in the memory systemââ¬â¢ (Gross, 2010) 9 Shane Galvin-061 AT-Applied Psychology Therapeutic Applications Cognitive Behavioural Therapy (CBT) Cognitive Behavioural Therapy is based on how our thoughts, feelings and behaviour all interact with each other; our thoughts influence our feelings and behaviour.CBT helps the client to develop alternate ways of thinking and behaving in order to reduce psychological distress. Through reflective processes and tasks such as homework, the clientââ¬â¢s maladaptive thought process and behaviour is challenged. Cognitive Behavioural Therapy is a blanket term for different therapeutic interventions that share similar characteristics. Two therapies which form the basis of CBT are Rational Emot ive Behaviour Therapy, developed by Albert Ellis in the 1950s, and Cognitive Therapy, developed by Aaron T.Beck in the 1960ââ¬â¢s. Beck puts forward the argument that our emotional reactions are essentially a function of how we construe the world. ââ¬Å"Depressed people see themselves as victims, and Beck sees them as victims of their own illogical self-judgements. Beckââ¬â¢s central idea is that depressed individuals feel as they do because their thinking is dominated by negative schemas. â⬠(Gross, 2010) Beck essentially implies that we interpret our reality by using our cognitive processes and our perception.If our perceptions are skewed because our cognitive processes are maladaptive or our methods of reasoning are incorrect then our emotions and behaviour become distorted from reality. In order to correct emotional or psychological disturbances then we must seek to examine the root of the problem, viewing this through the lens of cognition means that we must correct our thought process in order to correct the symptomatic behavioural and emotional disorder. Beck uses methodââ¬â¢s to treat a disorder depending on the disorder that the client suffers from. He stresses the importance of the quality of the relationship between the client and therapist.Beck also places particular emphasis on the client discovering misconceptions for themselves. (McLeod, 2008) Albert Ellisââ¬â¢ Rational Emotional Behavioural Therapy is quite contrasting to Becks method. Ellis Proposes that the therapist should be a teacher and that a warm personal relationship is unnecessary. REBT can also be highly directive, persuasive and confrontational. REBT also uses different methods of approach to a clientââ¬â¢s issue depending on the clientââ¬â¢s personality. Human cognition can be held responsible for the individualââ¬â¢s successes and accomplishments, according to CBT cognition can also be held responsible for our problems. You are responsible for the outcom e of the situationââ¬â¢ It emphasises control over oneââ¬â¢s behaviour and emotions through correcting thought processes. The nature of Cognitive 10 Shane Galvin-061 AT-Applied Psychology Psychology/Science allow cognitive theories to be tested in a variety of situations, for example Rimm & Litvakââ¬â¢s 1969 (McLeod, 2008) study shows that When experimental subjects are manipulated into adopting unpleasant assumptions or thought they became more anxious and depressed.Moreover, many people with diagnosed psychological disorders such as anxiety and sexual disorders have been found to display maladaptive thoughts and assumptions, making a case for the effectiveness of CBT. Aaron Beckââ¬â¢s work in researching depression and order disorders in clinical as well as laboratory settings and testing memory and other cognitive functions, and in particular his outcome studies have shown that CBT can be highly effective. CBT is also used in the treatment of drug abuse, bipolar disor der and in patients with cancer, HIV, OCD, PTSD and schizophrenia.It has also been theoretically applied in the treatment of psychopathy. Evaluation/Personal Learning Upon examining the field of Cognitive Psychology, I have learned that cognitive Psychology is adaptive. It evolves with the times and incorporates new technologies, but also has a serious grounding in scientific methodology in order to correctly examine and understand the human mind. Cognitive Psychology is informed by the greater umbrella that is cognitive science. For example it uses information from computer science and neuroscience in order to better understand the cognitive processes that exist in the human brain.Given that the ââ¬Ëmindââ¬â¢ is not a physical entity; this style of scientific inquiry may be the best approach in understanding it. There is a good scientific framework underlying Cognitive psychology which then allows the Psychologist to move forward and deal with issues presented by the mind. As we can see in Cognitive Behavioural Therapy, the therapist approaches the abstract nature of the mind by focusing on the underlying mental hierarchy. That being, Cognition, Emotion, Behaviour, in order to treat symptomatic issues, the therapist using this approach must deal with the thought processes that create these symptoms.The most important lesson that I have learned is that, while the mind is an abstract construct and is quite difficult to quantify, quantifiable information about physical constructs such as the brain and general human biology and chemistry and its influences informs the understanding of the human mind. 11 Shane Galvin-061 AT-Applied Psychology Bibliography Baddely, A. & Hitch, G. , 1974.
