A introduction into the piagets theory of intelligence

Over the first six weeks of life, these reflexes begin to become voluntary actions. For example, the palmar reflex becomes intentional grasping.

  • In the revised procedures, the participants explained in their own language and indicated that while the water was now "more", the quantity was the same;
  • A fourth course has been to focus on the role of knowledge in development;
  • To label someone as mentally retarded solely on the basis of a single test score, therefore, is to risk doing a disservice and an injustice to that person.

The main focus is still on the infant's body". Also at this phase, passive reactions, caused by classical or operant conditioningcan begin. Three new abilities occur at this stage: At this stage, infants will intentionally grasp the air in the direction of a desired object, often to the amusement of friends and family. Secondary circular reactions, or the repetition of an action involving an external object begin; for example, moving a switch to turn on a light repeatedly.

The differentiation between means and ends also occurs. This is perhaps one of the most important stages of a child's growth as it signifies the dawn of logic. This is an extremely important stage of development, holding what Piaget calls the "first proper intelligence ". Also, this stage marks the beginning of goal orientationthe deliberate planning of steps to meet an objective. Piaget describes the child at this juncture as the "young scientist," conducting pseudo-experiments to discover new methods of meeting challenges.

This marks the passage into the preoperational stage. Pre-operational stage[ edit ] By observing sequences of play, Piaget was able to demonstrate that, towards the end of the second year, a qualitatively new kind of psychological functioning occurs, known as the pre-operational stage, the second of Piaget's four developmental stages. During the pre-operational stage of cognitive development, Piaget noted that children do not yet understand concrete logic and cannot mentally manipulate information.

However, the child still has trouble seeing things from different points of view. The children's play is mainly categorized by symbolic play and manipulating symbols.

Such play is demonstrated by the idea of checkers being snacks, pieces of paper being plates, and a box being a table. Their observations of symbols exemplifies the idea of play with the absence of the actual objects involved.

Piaget's Theory of Cognitive Development

The pre-operational stage is sparse and logically inadequate in regard to mental operations. The child is able to form stable concepts as well as magical beliefs. The child, however, is still not able to perform operations, which are tasks that the child can do mentally, rather than physically. Thinking in this stage is still egocentricmeaning the child has difficulty seeing the viewpoint of others. The Pre-operational Stage is split into two substages: The symbolic function substage is when children are able to understand, represent, remember, and picture objects in their mind without having the object in front of them.

The intuitive thought substage is when children tend to propose the questions of "why? However, they now can think in images and symbols.

  • Some of the theories in the third group emphasize the importance of memory capacity;
  • Scores at the lower end have been given the labels borderline retarded 70 to 84 and severely retarded 25 to 39;
  • Most investigators also agree that differences in educational opportunities play an important role, though some believe that the main basis of the difference is hereditary;
  • Irreversibility refers to when children are unable to mentally reverse a sequence of events;
  • Without this additional instruction, however, the children did not always understand what they were supposed to do, and, because of this, they underperformed on the tests;
  • Most investigators also agree that differences in educational opportunities play an important role, though some believe that the main basis of the difference is hereditary.

Other examples of mental abilities are language and pretend play. Symbolic play is when children develop imaginary friends or role-play with friends. Children's play becomes more social and they assign roles to each other.

Some examples of symbolic play include playing house, or having a tea party. The type of symbolic play in which children engage is connected with their level of creativity and ability to connect with others. For example, young children whose symbolic play is of a violent nature tend to exhibit less prosocial behavior and are more likely to display antisocial tendencies in later years.

Egocentrism Egocentrism occurs when a child is unable to distinguish between their own perspective and that of another person.

Post-Piaget theories

Children tend to stick to their own viewpoint, rather than consider the view of others. Indeed, they are not even aware that such a concept as "different viewpoints" exists. In this experiment, three views of a mountain are shown to the child, who is asked what a traveling doll would see at the various angles.

The child will consistently describe what they can see from the position from which they are seated, regardless of the angle from which they are asked to take the doll's perspective.

Piaget coined the term "precausal thinking" to describe the way in which preoperational children use their own existing ideas or views, like in egocentrism, to explain cause-and-effect relationships. Three main concepts of causality as displayed by children in the preoperational stage include: An example could be a child believing that the sidewalk was mad and made them fall down, or that the stars twinkle in the sky because they are happy.

Artificialism refers to the belief that environmental characteristics can be attributed to human actions or interventions.

Piaget's theory of cognitive development

For example, a child might say that it is windy outside because someone is blowing very hard, or the clouds are white because someone painted them that color. Finally, precausal thinking is categorized by transductive reasoning. Transductive reasoning is when a child fails to understand the true relationships between cause and effect.

For example, if a child hears the dog bark and then a balloon popped, the child would conclude that because the dog barked, the balloon popped. Intuitive thought substage[ edit ] At between about the ages of 4 and 7, children tend to become very curious and ask many questions, beginning the use of primitive reasoning.

There is an emergence in the interest of reasoning and wanting to know why things are the way they are. Piaget called it the "intuitive substage" because children realize they have a vast amount of knowledge, but they are unaware of how they acquired it. Centrationconservationirreversibilityclass inclusion, and transitive inference are all characteristics of preoperative thought. Centration is the act of focusing all attention on one characteristic or dimension of a situation, whilst disregarding all others.

Conservation is the awareness that altering a substance's appearance does not change its basic properties. Children at this stage are unaware of conservation and exhibit centration.

  • During this period, a child learns how to modify reflexes to make them more adaptive, to coordinate actions, to retrieve hidden objects, and, eventually, to begin representing information mentally;
  • According to Piaget's theory children should not be taught certain concepts until they have reached the appropriate stage of cognitive development;
  • There is more variability within groups than between groups;
  • Third, the significance of a given test score can be different for different people;
  • If the twins were raised in separate environments, and if it is assumed that when twins are separated they are randomly distributed across environments often a dubious assumption , then the twins would have in common all of their genes but none of their environment, except for chance environmental overlap;
  • Although the kinds of complex tasks discussed so far belong to a single tradition for the measurement of intelligence, the field actually has two major traditions.

Both centration and conservation can be more easily understood once familiarized with Piaget's most famous experimental task. In this task, a child is presented with two identical beakers containing the same amount of liquid. The child usually notes that the beakers do contain the same amount of liquid.

When one of the beakers is poured into a taller and thinner container, children who are younger than seven or eight years old typically say that the two beakers no longer contain the same amount of liquid, and that the taller container holds the larger quantity centrationwithout taking into consideration the fact that both beakers were previously noted to contain the same amount of liquid.

One more step

Due to superficial changes, the child was unable to comprehend that the properties of the substances continued to remain the same conservation. Irreversibility is a concept developed in this stage which is closely related to the ideas of centration and conservation. Irreversibility refers to when children are unable to mentally reverse a sequence of events.

In the same beaker situation, the a introduction into the piagets theory of intelligence does not realize that, if the sequence of events was reversed and the water from the tall beaker was poured back into its original beaker, then the same amount of water would exist.

Another example of children's reliance on visual representations is their misunderstanding of "less than" or "more than".

When two rows containing equal amounts of blocks are placed in front of a child, one row spread farther apart than the other, the child will think that the row spread farther contains more blocks. Children's inability to focus on two aspects of a situation at once inhibits them from understanding the principle that one category or class can contain several different subcategories or classes.

The girl knows what cats and dogs are, and she is aware that they are both animals. However, when asked, "Are there more dogs or animals? This is due to her difficulty focusing on the two subclasses and the larger class all at the same time. She may have been able to view the dogs as dogs or animals, but struggled when trying to classify them as both, simultaneously. Transitive inference is using previous knowledge to determine the missing piece, using basic logic. Children in the preoperational stage lack this logic.

An example of transitive inference would be when a child is presented with the information "A" is greater than "B" and "B" is greater than "C".

This child may have difficulty here understanding that "A" is also greater than "C". Concrete operational stage[ edit ] The concrete operational stage is the third stage of Piaget's theory of cognitive development.

During this stage, a child's thought processes become more mature and "adult like". They start solving problems in a more logical fashion. Abstract, hypothetical thinking is not yet developed in the child, and children can only solve problems that apply to concrete events or objects.

At this stage, the children undergo a transition where the child learns rules such as conservation. Inductive reasoning involves drawing inferences from observations in order to make a generalization. In contrast, children struggle with deductive reasoningwhich involves using a generalized principle in order to try to predict the outcome of an event. Children in this stage commonly experience difficulties with figuring out logic in their heads.

For example, a child will understand that "A is more than B" and "B is more than C". However, when asked "is A more than C? Two other important processes in the concrete operational stage are logic and the elimination of egocentrism. Egocentrism is the inability to consider or understand a perspective other than one's own. It is the phase where the thought and morality of the child is completely self focused. For instance, show a child a comic in which Jane puts a doll under a box, leaves the room, and then Melissa moves the doll to a drawer, and Jane comes back.

A child in the concrete operations stage will say that A introduction into the piagets theory of intelligence will still think it's under the box even though the child knows it is in the drawer.

See also False-belief task. Children in this stage can, however, only solve problems that apply to actual concrete objects or events, and not abstract concepts or hypothetical tasks.

Understanding and knowing how to use full common sense has not yet been completely adapted.

502 Bad Gateway

Piaget determined that children in the concrete operational stage were able to incorporate inductive logic. On the other hand, children at this age have difficulty using deductive logic, which involves using a general principle to predict the outcome of a specific event. This includes mental reversibility. An example of this is being able to reverse the order of relationships between mental categories. For example, a child might be able to recognize that his or her dog is a Labrador, that a Labrador is a dog, and that a dog is an animal, and draw conclusions from the information available, as well as apply all these processes to hypothetical situations.

However, it carries over to the formal operational stage when they are then faced with abstract thought and fully logical thinking. Testing for concrete operations[ edit ] Piagetian tests are well known and practiced to test for concrete operations. The most prevalent tests are those for conservation.

One example of an experiment for testing conservation is the water level task.
