Classical Ideas Of Cognitive Development Psychology Essay

There are two traditional theories of cognitive development. The the one which I will focus on is Piagets theory of cognitive development. He hypothesized that learning is a physical, natural function of interacting successfully with the environment (Phillips, 1998). This is actually the basis for his theory. Piaget's theory of cognitive development is dependant on two natural tendencies. Both tendencies are company, and adaption. Organisation as Piaget saw it, said that humans are designed to organise their observations and encounters into coherent models of meanings (Eggen, 1999). This organisation of observation makes the thinking process more efficient. If a person can put the things they observe in some type of order the easier it is to remember and apply their observations. Adaption according to Piaget's theory, is the tendency to change to the surroundings. Adaption is a process where we create matches between our original observations and new ones that might nearly fit mutually. Our original observations and conceptions are called our schemas. To adapt to new observations and encounters into our schemas we use one of two techniques. We are able to assimilate that information by adding it as well as old schemas or conceptions. In the event the observations don't fit effectively into our existing schemas we use the second of the adaption techniques, we hold or change our schema to fit our observation. Piaget never said that our schemas had to be right or wrong. Our schemas are based on our very own observations and experience (Eggen, 1999). We adapt to things because we live motivated by the urge to get things "fit collectively" or even to maintain what Piaget calling equilibrium. Once we use our adaption and corporation we constantly get what to fit together. You will find other natural functions that also help in cognitive development. Normal progress of a person helps a person to adjust and understand things better. Community interaction is also a biotic factor in cognitive development. Humans use other humans to check on their own schemas with others. We figure out how to use others thought associations to help them fit their schemas alongside one another better for us to have a better understanding of ourselves.

Piaget used the two natural tendencies and other biological functions of humans to create four levels of cognitive development ( Eggen, 1999). Piaget said that each developing human being must go through each stage to be able. The first level is the sensory-motor level. The approximate age group of the humans in this stage is labor and birth to 2 years. Piaget says that children learn through manipulating concrete materials. Half-way through this level the child has the ability to know that whenever an thing leaves their view they don't vanish they still are part of the physical world. This is actually the concept of object permanence. It also allows the child to hold a thought in their brain. The Second level of Piaget's cognitive development is the pre-operational stage. This stage occurs from 2 - 7 years of age and in it children get better at many symbols and concrete ideas. In this level the kid is also very egocentric. They have got trouble looking at several characteristic of the thing their experiencing this is tested in Piaget's experiment "the three mountains" which helped support his theory of egocentrism. The three mountains experiment was carried out by using three mountains which were coloured differently with different things on top (snow, house, combination). A doll was placed in different positions and the child was asked what the doll can see depending on which position it was put. This test helped support Piaget's theory of egocentrism because of the most these children using their pre-operational thinking that were ever the doll was put it could have exactly the same view point that they saw (Davenport, 1994). This was later replicated by Hughes (1978) displaying that it might easily be generalised.

Hughes (1975) argued that the three mountains process did not seem sensible to the kids and was made more difficult because the children had to match the doll's view with an image. Hughes devised a task which made sense to the child. He confirmed children a model comprising two intersecting walls, a 'son' doll and a 'policeman' doll. Then placed the policeman doll in various positions and asked the kid to hide the young man doll from the policeman. Hughes have this to be sure that the child understood what was being asked of him, so if he made mistakes they were explained and the kid tried again. Oddly enough, very few mistakes were made. The test then started out. Hughes earned another policeman doll, and put both dolls by the end of two walls. The child was asked to cover up the young man from both policemen, in other words he had to adopt account of two different tips of view. Hughes' test comprised children between three and a half and five years of age, of whom 90 per cent gave correct answers. Even though he devised a more complex situation, with more walls and a 3rd policeman, 90 % of four-year-olds were successful. This demonstrates children have mainly lost their egocentric thinking by four years, because they're able to take the view of another. Hughes' test allowed them to show this because the task made sense to the child, whereas Piaget's did not.

In the 3rd level of Piaget's theory called the concrete-operational level, children time 7- 11 begin to think logically, learn about regulations of conservation, and serial buying. Conservation is the idea that matter is usually the same despite the change in shape of an object. Serial ordering has been in a position to recognise that things can be placed in order. Piaget thought concrete operational children got difficulty in considering ideas that were hypothetical or abstract. Piaget would asses children's thinking with conservation duties i. e. lots of counters in a row does not change even though they are then spaced out. He concluded that pre-operational children failed at this task because they cannot conserve amount, whereas the concrete functional children can understand the change.

Piaget's conservation experiments have been criticised scheduled to his technique he used. Rose & Blank (1974) suggested that the utilization of two questions may have lost his younger children participants. In the initial experiments the children were shown an image of items i. e counters prearranged and then asked the same question with the counters rearranged. A pre-operational child could perceive that being asked double then something must be different, so the answer will be different then before, this may impact the demand characteristics of the experiment because it usually leads the child to behave in a particular way. Rose & Blank(1974) tried undertaking the experiment with just one question after they had been rearranged and uncovered that pre-operational children could deal a lot better. Donaldson (1978) criticised Piaget's test proclaiming that the demand characteristics of his test was deliberately endeavoring to suggest to the kid that the experimenter was looking for a different response. Donaldson & McGarrigle (1974) carried out a similar test utilizing a 'naughty teddy' that could accidentally disseminate one row of beads very much like Piaget's test. The results revealed that children were able to conserve more leading to them having a much better performance compared to Piaget's initial task. However, more recent research has concluded that Donaldson might have been mistaken anticipated to it being possible that the children were more assimilated in the 'naughty teddy' and didn't realize the beads had been rearranged, so still mentioned these were still the same amount.

The fourth and final level is the formal-operational level. From get older 12 to adult, learners are able to think abstractly about real things. In addition they use reasoning and logic to believe abstractly about those objects. In such a highest of the level of development learners learn to use complex terminology varieties such as metaphors. Piaget & Inhelder (1956) proven this with the 'beaker problem'. Individuals received four beakers of colourless liquids and asked to discover which will create a yellow liquid. Younger participants tried all sorts of combinations whereas the older children took a far more systematic methodology until they got the right solution. However, the results from this cannot be general.

There are some weak points of Piaget's theory. The first is that Piaget underestimated children's features. Most children undertake the first two levels considerably faster than Piaget said they would. Alternatively the last two levels Piaget overestimated the skills of humans to understand the stage. Due to the other biological factors each young one will proceed through each level in their own time, so at confirmed age not all children are in the same cognitive stage ( Eggen, 1999).

Much of the criticism of Piaget's work is when it comes to his research methods. A significant source of ideas for the theory was Piaget's observations of his own three children. In addition to this, the other children in Piaget's small research sample were all from well-educated pros of high socioeconomic position. Because of this unrepresentative sample, it is difficult to generalise his research.

Comparison of Two Cognitive Development Theories

Cognitive development is defined as the regions of neuroscience and mindset studies, focusing on adolescent development with special focusing on information processing, language learning, conceptual resources, perceptual skill, and brain development. Jean Piaget and Lev Semyonovich Vygotsky were two pioneers in the field of cognitive development. With this article I will compare each theorist's views on the type or development of intellect. I will also compare their views on the phases of development from beginning through adolescence. And lastly I will combine possible classroom applications of each theorist's views.

Similarities in Cognitive Development

Like Piaget, Lev Vygotsky thought that cognitive development occurs in steps that are the same for any individuals. Vygotsky theorised the first step in intellectual development is learning that action and sounds have interpretation. Second, that step in cognitive development was doing the new action or sound. And lastly, using the actions and sounds to think and solve problems without the help of others, described by Vygotsky as self-regulation. Glassman (1999) noted that Piaget centered on the natural regulations of intellectual development while Vygotsky concentrated on the impact of sociable functions and culture. Although both Vygotsky and Piaget recognised the importance of social relationships in cognitive development, it was Vygostsky who believed the most helpful relationships were people that have peers. Piaget thought that connection with peers urged disequilibrium or cognitive discord forcing change or "development. " Vygotsky theorised that words was the most crucial tool for development. Piaget, however, didn't think that language played a huge role. They both assumed that egocentric conversation is important to a child's development.

Differences in Cognitive Development

While Piaget presumed that intellectual development was highly personal, and that folks learned from encounters as opposed to the teaching of concepts and thought techniques, Vygotsky believed that learning development was a cultural process directly linked to the teaching of information, which learning proceeded development. Vygotsky theorised that terms was the main element to cognitive development, and learning was affected by the culture of the individual. He believed that a child first designed the conversation of others into their personal knowledge and procedures it, known as private speech, and later they used this "private speech" in initiatives to solve responsibilities. Vygotsky redefined this theory into what we now know as The Area of Proximal Development. (ZPD) defines intellectual development as the capability to use thought to control our own activities, but first we should master cultural communication systems, and then use these systems to regulate our thought processes. Children learning with in the (ZPD) focus on jobs that they cannot complete by itself, but could actually finish with the help of and competent trainer. These teachable moments illustrate Vygotsky's theory that learning proceeded development, and that cooperative learning promotes progress learning. His theory identified language in an effort to pass on ethnical values and that teaching dialect was the medium had a need to develop cognitive thought techniques.


Piaget's theory suggests that children progress intellectually through four phases of development: Sensorimotor, Pre-operational, Cement Functions and Formal Operations. At each one of these levels, Piaget posited, there have been different troubles that the child needed to deal with. He also indicated that unless the kid mastered the duties in one level, he or she could not excel at the jobs in other stages. There are issues that are inherent in all ideas which posit "stages" of development. Development does not arise in discrete phases - it occurs whenever the environment places increased demands and/or provides less support to the average person. In our world, it simply looks that people all tend to place these demands on children at around the same time - this makes it appear that we are witnessing "stages" of development.

Zimmerman conducted some various studies start surrounding the 1960's or more until today demonstrating that if the surroundings placed certain needs, then children would exceed what was expected of them. Baillargeon et al (1985), in the 'drawbridge' review; a coloured box was placed in the path of the drawbridge. In the possible event, the drawbridge discontinued at the main point where its course would be obstructed by the box. Within the impossible event, the drawbridge seemed to go through the box and ended up lying even, the box seemingly having disappeared.

Baillargeon found that infants spent much longer considering the impossible event. She figured this indicated surprise on the babies' part and that the infants were amazed because that they had expectations about the behaviour of physical things that the impossible event acquired violated. In other words, the infants understood that the field still been around behind the drawbridge and, furthermore, that they realized that one stable thing cannot just pass through another. The newborns in this analysis were five calendar months old, an era at which Piaget would say that such knowledge is quite beyond them. Infants could identify, to a reasonable degree, incidents which violated the regulations of physics, even though, Piaget mentioned that babies at the "sensorimotor" stage could not do it.

Another critique, corresponding to Das Gupta & Bryant (1988). Children were able to follow simple transformations, even though; Piaget noted that children at the "pre-operational" stage could not accomplish that. Hughes (1978) mentioned that children could actually take the point of view of multiple people even though; Piaget known that children at the "pre-operational" stage could not accomplish that.

Light, Buckingham & Robbins (1979) discovered that when children were educated to pay attention to the concrete properties of a meeting (e. g. , pouring fluids into different measured beakers), then they were able to do so, even though, Piaget noted that children at the "pre-operational" stage cannot do which means this contradicted Piaget as he was instrumental in getting visitors to think about children as those who are developing. However, children develop in radically different ways.

Applied to Education

To apply Piaget's theory in the school room, we should keep in mind the student's developmental level and items our teaching toward that. To possess infant children thinking abstractly is impossible. They would never completely understand the idea because they're not ready developmentally. Since Piaget's theory revolves around the biological adaption to environment we have to instruct so that students can see relationships between principles. A great way to do those in primary schools is to teach with thematic models. This lets the students relate all subjects mutually through the main theme.

Piaget recommended that learning should be supported by material, experience and ideas which are appropriate for the child's degree of development (Montessori, 1912). For example, matching to Piaget's theory, 5 and 6 six-year-olds will find it better to understand the idea of addition if they're given objects to manipulate (perhaps using counters to include up amounts) than if they just see quantities written down. Regarding to Piaget, what children can learn depends upon their current level of cognitive development. This prediction has already established little support, some makes an attempt have been made to teach concrete businesses to preschool children but was unsuccessful as the standard age group is 7.

According to Piaget, children learn best in energetic self-discovery. They learn best in their productive involvement with the world around them. Teachers can encourage this by creating circumstances of disequilibrium, where the child's existing schemas or cognitive buildings are been shown to be limited. Disequilibrium can be created by asking children difficult questions, and by encouraging these to ask questions. Doise & Mugny (1984) argued that cognitive development consists of the quality of socio-cognitive issue, which is produced by contact with the differing views of others. This is backed by Ames & Murray (1982), in a study of children aged 6-7 who experienced failed on conservation duties. Some children were given corrective feedback, and more were exposed to children who already realized about conservation. Still others were combined with children who possessed also didn't conserve, but who had provided another type of incorrect answer from theirs. Children in the last condition showed the greatest improvement in capacity to conserve.

A major weakness of Piagets work to education is that it only targets mathematical or logical principles so that it does not enable other issues i. e. background, dialects etc. Vygotsky's key contribution to educational practice was the notion that children typically learn best in a communal context where somebody who is more competent carefully manuals and stimulates their learning attempts. Thus, children can be regarded as apprentices who are taught the required skills by those already having them by means of scaffolding (Lumber et al, 1976). His methodology can explain ethnical differences since it is based on the social framework. However, one might expect understanding how to be considerably faster than it is if all that was required was the advice of experts. Through Vygotsky's theory the child can learn better because of peer tutoring, cooperation with others, play as it will involve ethnical activities (Bennett & Dunne, 1991).
