Critically evaluate the empirical support for Piagets theory of the stages of cognitive development Introduction Critically evaluate the empirical support for Piagets theory of the stages of cognitive development IntroductionReferences.Related Introduction Cognitive development overlooks the way children learn which Piaget (1896-1980) has had a great influence on. Piaget observed children throughout activities by interacting with them verbally and active listening. Piaget (1952) believed that children move through various stages in order to develop.   In order for children to develop they had to pass the four stages, Piaget (1952) names the stages as follows, sensorimotor, pre-operational, concrete operations and formal operational. However there have been many criticisms made by many theorists such as siegler, case, Lewis etc. In this essay I will be evaluating Piaget’s theory stages of development critically and coming to a conclusion. Piaget had a broad horizon on cognitive development. He felt that in order for a development to be passed a child creates schemas.   Piaget (1951) schemas are senses of experiences gained by a child from birth. A schema represents a child’s physical and mental capability, for an example a new born child begins to grasp, suck, blink etc. In order for a child to go through the next stage he should be intellectually and mentally fit. The first stage is the sensori-motor, this stage start from birth to 2 years. During this stage children begin to use their senses to create senses in order to develop such as see, hear, touch etc. Piaget (1952) did a task with children ages 8 to 12 months. He called this task â€Å"object permanence†, where he hid an attractive toy away from the child. The child responded by pushing objects away to find the toy. His findings showed him that children began to problem solve and have an understanding. The second stage is the preoperational stage. This stage occurs from 2 to 7 years. Piaget (1936) felt that children were not intellectually capable as their perception was dominating the way they saw situations. He believed that there were many limitations to the way children will think during this stage. The first limitation was egocentration where their own perceptions are being dominated by themselves. Piaget felt that young children are unable to express their views other than their own. In order to prove this he created a task called â€Å"three mountains task†. He came to the conclusion that children up to the age of seven could not identify what the doll could see as they would only answer what they could. The second limitation to this stage is centration which Piaget (1936) believed that children could only focus on one situation going on at one time ignoring others. Piaget (1952) created a task called â€Å"conservation†, this task involved objects which were t ransformed into different lengths, shapes etc. From this task he found out that children cannot focus or understand the concept of height while concentrating on the width. Robert Siegler (1981) replicated Piaget’s (1958) â€Å"Balance Beam† task to see why children could not solve conservation tasks. However Siegler (1981) believed that there are some strategies which children use in order to complete tasks. From his experiment he found that children below 5 could not use the first strategy but used strategy 2 and 3. The third stage is concrete operations. This stage starts from 7 to 12 years. This stage strongly focuses on reasoning. At this stage children are able to see and understand conservation tasks, size, height etc. There are 4 areas which consist within this stage conservation, classification, seriation. Conservation involves children to problem solve mathematically. Classification is for children 7 to 10, Piaget (1967) has said classification is what children in those ages should be able to understand and group objects relating them to their characteristics. Seriation is children able to put things in order for example in size, colour shape, numbers etc. This stage is allowing children to experiment with real objects in order to explore and problem solve. Piaget (1967) did an experiment for seriation with sticks where he found out that, children can put into series of order but make many mistakes.   He found that above 6 years can put in order in no time and correctly. The final stage is formal operational. This stage occurs in children around 11 according to Piaget (1958). At this stage children are thinking like adults where they can easily problems in their head with ease. Piaget (1958) constructed a task called â€Å"pendulum†. From this task he found out children do little mistakes but learn from them and all three stages pre- operational, concrete and formal operational are concurred and passed. Lewis (1981) did an experiment to show that not all teenagers at the age of 11 can think like adults, he found out that 50-60% teenagers used formal operations. This shows that not all teenagers including adults use this stage. However Bryant (1974) had criticised that tasks that Piaget (1936, 1951, 1952) did to prove his theory were very hard for children to do. Bryant (1974) proved that Piaget was a bit harsh in tasks with children so he constructed a task where he found out that children under 5 were able to do the tasks without any hesitation. This shows the Piaget (1952) did have a good theory but didn’t have the right task for the age group which the children didn’t answer correctly. Robbie case (1992, 1998) did an experiment to see that a child’s development is not just about schemas or to see their cognitive development, but it includes information processing, which is internal capacity of a child.   Cases’ (1992, 1998) theory shows that children have not got enough memory capacity to help them process and develop. So as children grow older they concur the stage. This essay has come to the conclusion that Piaget’s theory has a good source of empirical support to prove his theory. Piaget himself has underpinned numerous tasks such as 3 mountains task, pendulum, object permanence, in order prove his stages of development. However other theorists such as Bryant (1947), Case (1992), Lewis(1981) and Siegler (1981) have proved that there more to the stages of development for example case (1992) has showed that information processing has an equivalent contribution. Nevertheless Piaget had a great impact on cognitive development whereas as many theorists have been inspired. References. Berk. E. L. (2009). Child Development.

Merketing Segmentation of The Food Industry Essay

Merketing Segmentation of The Food Industry - Essay Example Markets have always been segmented and products have been differentiated on the basis of the ways in which suppliers have applied different techniques of competing in the market. The crucial evidence for the above aspect collected in recent times is that researchers have been using behavioural and economic theories along with sophisticated analytical techniques for identifying the various market segments and opportunities for product differentiation. The concepts of market segmentation and product differentiation have been discussed in literature for long. Shaw (1912) has described the strategy of market segmentation and product differentiation as that of trying to cater to human needs and wants more accurately than competition. The result of market segmenting and product differentiating is the creation of a potential which attains a price level which is higher than prevailing stock commodity. Researchers have identified the recent changes in the market environment of firms which hav e presented with new opportunities and chances of further segmentation of the market. However, the aspect of the possibilities of identifying the groups of customers as individual segments in the market in reality is an empirical one. Researchers are of the opinion that if it is possible to segment the market into individual and homogeneous segments, market segmentation could be effective only if the manageability and efficiencies of the marketing activities could be substantially influenced by the distinguishing and different groups of customers (Wedel & Kamakura, 2000, p.4). Globalization and technological advancement across the world along with fresh new developments have provided marketers with in-depth information regarding the actual behaviour of customers and having direct access to such information through database marketing or demographic segmentation (Wedel & Kamakura, 2000, p.4). As a consequent of this, the marketers have been found to be focussing more on the small segm ents using concepts like direct marketing and micro marketing approaches. However on account of globalization, the leading multi product manufacturers have been looking at the global markets beyond the geographical boundaries (Yankelovich, 1964). It is seen that if the various market segments respond to the marketing efforts they are considered to be responsive to the segmentation strategies. Responsiveness accounts for the success factor for any market segmentation strategy. Mere response from the segments to the advertising

Advantages of Living with Parents in College Essay Example for Free

Advantages of Living with Parents in College Essay When we see graduation caps in the sky, accompanied with laughter, applause and cry, it is a signal that we just welcome ourselves to the new world after high school. As we step into a college world as a new and fresh collegian, there are many facets that we have to think and decide, especially accommodation. Some people choose to live in the college dorms – making new friends and having more social activities, some other choose to share a house with couple of housemates, or just simply rent a flat and live independently. But, there are some that just decide to stay in town and live with their family. This last choice has three main advantages that we can consider: expense, support, and facilities. The first basic advantage of living with family, or parents, is expense. Imagine hearing your door knocked in the morning, and facing your landlord who demands your rent paid as the start of the day? Or when you can’t dial any number in the phone because you haven’t paid the telephone bill? And, the worst, when you don’t even have enough money to buy yourself breakfast because your parents haven’t sent you any monthly money? Well, you won’t have that drove of problems when you live with your parents. Expenses like food (especially healthy and delicious food), telephone, electricity, and many other will be covered by your parents, so that you can still save your own personal money. You don’t even have to pay more for movies or other leisure things when you hang out with your family. This first aspect of living with family is very, very efficient and helpful to save money! Another important facet of living with your parents is support. Being with family and living in your own home help you a lot when you have your transition phase from high school or college. It would be easier not to face other transition major adaptations, like being lonely in your own room, feeling aloof from family, meeting new hostile roommate who you are not connected to and start to adjust your own finance. You will have your family right beside you, and you will always feel like home. You will also be discipline and controlled since you still have curfew and ‘parents rules’. You can also keep your old friends around you, and you won’t even have to give up your old routines like playing tennis with your dad every Saturday or working in the grotesque diner down the street. This second advantage can make you feel like you are still the old you and you don’t even have to give up a thing. Last but not least, facilities can also be another advantage of living with your parents. You will still have anything you need for college like computer, electricity, internet, printer, scanner, or even fax machine, and they are all for free! Yet again, no expenses wasted. You also don’t have to wait the jamming docket bus that comes late in the morning, because you have transportation that keeps you punctual – somehow going to college in your mum’s car is okay! There won’t be any piling laundry because they are all taken care of. You can also have your own bathroom with hot water and hairdryer, plus clean towels every night. The point is it will be much easier for you to have your needed facility when you’re at home, especially without spending any cent. Living outside your house, like in the dorms or flats, won’t give you this kind of comfort. These three advantages show us that living with parents might be embarrassing and less challenging, but it can be considered since it saves a lot of money and gives you a lot of comfort and support. It can even be less expensive than sharing a house with other housemates! From not paying much of expenses, living in your old room every night, and having more facilities, doesn’t it sound like fun?

Indifference Breeds Evil Essay -- Philosophy, Truth

Indifference Breeds Evil Norman Cousins, an American journalist and professor, once said, â€Å"The individual is capable of both great compassion and great indifference. He has it within his means to nourish the former and outgrow the latter.† Choices comprise the essence of life. Many people assess the circumstances they encounter in their life and tend to react in their best interests. When a fellow man requires a helping hand most people pay no heed because it’s the easy way out. However, other people will go out of their way to lend a hand even if it takes exertion on their part and they will be triumphant, knowing they created a better world. In contrast, those who are indifferent to another’s plight will bring more evil into the world. In conclusion, a person sometimes needs to let go of his indifference to face the truth of what is right. In the following stories, we will show how the choices people make effect society for the good or the bad. We will explore the colonists first who were faced with a choice during the Revolutionary War. The colonists of America started to rebel against the mighty British Empire for a number of reasons. John Locke had written about the â€Å"social contract† which meant that the government can only be of authority if it has consent of the governed. Locke continues and says that if the government abuses the rights of the governed the people can rebel and overthrow the government. This idea began to germinate in the minds of the colonists as the British government began forcing unreasonable tariffs on them. The Sugar Act, Stamp Act, and the Townshend Acts were all different taxes that the British parliament placed on goods and commodities at a time when the economy was at a low. The colonists starte... ... grow out of a widespread pursuit of individual interests,† there’s a need for â€Å"†¦cooperative efforts†¦of many people† (Velasquez, Andre, Shanks, S.J. and Meyer 2). The â€Å"common good† is something with which everyone can partake and enjoy. For example, a clean unpolluted environment. The problem with the â€Å"common good† is that not everyone in society will be motivated towards one goal because people will support their own interests and not towards the goal of the â€Å"common good.† Even though the ideal society of everyone working toward the â€Å"common good† can never become reality it is a point to ponder. People should reflect if their actions are going to benefit society or cause distress or hardship on others. Our society stresses individualism, but we cannot remain indifferent to the shared goals we all have in common. (Velasquez, Andre, Shanks, S.J. and Meyer)

Marketing Spotlight Coca-cola Essay

1- What have been the key success factors for COCA-COLA? From the text, it seems that the key success factors are summarized by: Marketing: Coca-Cola is seen as one of the founding fathers of the modern day marketing model. They were among the pioneers of advertising techniques and styles used to capture an audience. Innovation: It was apparent that the market was changing and in order to keep up with these changes, Coca-Cola had to move from a single core product to a total beverage company.

What should they watch for? global brand strategy and local, it must think global but act local, now the effectiveness of TV ads is declining due to media fragmentation and use of devices like TIVO that let viewer zap commercials. Flight ads are that ad, which temporarily attracts the customers but doesn’t say much about core values of the company or the product. An ad should describe a brands personality and value driver, which drives the personality. Most of the recent ads just endorsed by celebrities don’t much explain about cokes value, in long run this may make people to forget what coke stand for. They should work to make values more fresh and relevant and study alternatives for communications strategies. They should find another ways to enter some countries that COCA-COLA doesn’t enter. 3- What recommendations would you make to their senior marketing executives going forward? What should they be sure to do with their marketing? Position it differently for example like refresher for a farmer/ who is doing hard work in farmland to penetrate deep into Bottom of the pyramid. Think global but act local. Flight ads are that ad, which temporarily attracts the customers but doesn’t say much about core values of the company or the product. An ad should describe a brands personality and value driver, which drives the personality.

How to Write a Critical Thinking Paper

How to Write a Critical Thinking Paper? Writing a critical thinking paper involves the kind of analysis that reveals internal logic of the subject matter chosen. It is not merely description of facts and data to back the argument. It is the analysis of how things happen to be, why they are done in a particular way and what development might be in the regarded framework. The analysis of the topic information, preceding critical thinking paper, includes critical reading and proper information arrangement. Start with skimming the sources on subject matter to outline the topic and to have a clear picture in front of you. Reread the most interesting and informative articles to pick up subject relevant details. Trace internal logic of facts and data, look up for unique ways of thinking regarding your topic. Use short notes or note cards to arrange information for structure analysis. Process the data and create your own argument based on the accumulated data. Tend to use trusted and reputable sources. As soon as you are done with the analytical part, make draft writing on a pad or sheet of paper. Hand writing is a mechanical action that directly appeals to mental categorization mechanisms via language, which automatically add to your performance in thinking and writing. Use a standard structure with introductory paragraph grabbing readers’ attention and outlining the overall paper structure. The main part renders the argument, reasoning and your personal ideas supported by facts and their critical analysis. Start a new paragraph for every new idea and provide transition to the paragraph that follows. Draw a unique and original conclusion leaning upon the data analyzed and your own view of the subject matter.
