Return to Contents "The last two decades of infancy research have seen dramatic changes in the way developmental psychologists characterize the earliest stages of cognitive development. It includes the acquisition and consolidation of knowledge.
Schemas Imagine what it would be like if you did not have a mental model of your world. It would mean that you would not be able to make so much use of information from your past experience or to Cognitive development and learning future actions.
Schemas are the basic building blocks of such cognitive models, and enable us to form a mental representation of the world. Piaget emphasized the importance of schemas in cognitive development and described how they were developed or acquired.
A schema can be defined as a set of linked mental representations of the world, which we use both to understand and to respond to situations. The assumption is that we store these mental representations and apply them when needed.
For example, a person might have a schema about buying a meal in a restaurant. The schema is a stored form of the pattern of behavior which includes looking at a menu, ordering food, eating it and paying the bill.
The schemas Piaget described tend to be simpler than Cognitive development and learning - especially those used by infants. He described how - as a child gets older - his or her schemas become more numerous and elaborate.
Piaget believed that newborn babies have a small number of innate schemas - even before they have had many opportunities to experience the world. These neonatal schemas are the cognitive structures underlying innate reflexes.
These reflexes are genetically programmed into us. Shaking a rattle would be the combination of two schemas, grasping and shaking. Assimilation and Accommodation Jean Piaget ; see also Wadsworth, viewed intellectual growth as a process of adaptation adjustment to the world.
Assimilation — Which is using an existing schema to deal with a new object or situation. Accommodation — This happens when the existing schema knowledge does not work, and needs to be changed to deal with a new object or situation.
Equilibration — This is the force which moves development along. Piaget believed that cognitive development did not progress at a steady rate, but rather in leaps and bounds. However, an unpleasant state of disequilibrium occurs when new information cannot be fitted into existing schemas assimilation.
Equilibration is the force which drives the learning process as we do not like to be frustrated and will seek to restore balance by mastering the new challenge accommodation. Once the new information is acquired the process of assimilation with the new schema will continue until the next time we need to make an adjustment to it.
Example of Assimilation A 2-year-old child sees a man who is bald on top of his head and has long frizzy hair on the sides.
Sensorimotor stage birth to age 2 2. Pre-operational stage from age 2 to age 7 3.
Concrete operational stage from age 7 to age 11 4. Each child goes through the stages in the same order, and child development is determined by biological maturation and interaction with the environment. Although no stage can be missed out, there are individual differences in the rate at which children progress through stages, and some individuals may never attain the later stages.
Piaget did not claim that a particular stage was reached at a certain age - although descriptions of the stages often include an indication of the age at which the average child would reach each stage.
Sensorimotor Stage Birth-2 yrs The main achievement during this stage is object permanence - knowing that an object still exists, even if it is hidden. It requires the ability to form a mental representation i. Preoperational Stage years During this stage, young children can think about things symbolically.
This is the ability to make one thing - a word or an object - stand for something other than itself. Thinking is still egocentricand the infant has difficulty taking the viewpoint of others.
This means the child can work things out internally in their head rather than physically try things out in the real world. Children can conserve number age 6mass age 7and weight age 9. Conservation is the understanding that something stays the same in quantity even though its appearance changes.
Formal Operational Stage 11 years and over The formal operational stage begins at approximately age eleven and lasts into adulthood. During this time, people develop the ability to think about abstract concepts, and logically test hypotheses.
Piaget has been extremely influential in developing educational policy and teaching practice. The result of this review led to the publication of the Plowden report Discovery learning — the idea that children learn best through doing and actively exploring - was seen as central to the transformation of the primary school curriculum.
Readiness concerns when certain information or concepts should be taught. According to Piagetassimilation and accommodation require an active learner, not a passive one, because problem-solving skills cannot be taught, they must be discovered.
Within the classroom learning should be student-centered and accomplished through active discovery learning.Parents, family members, friends, teachers, and caregivers play a vital role in supporting the cognitive development of infants by providing the healthy interpersonal or social-emotional context in which cognitive development unfolds.
Piaget () was the first psychologist to make a systematic study of cognitive development. His contributions include a stage theory of child cognitive development, detailed observational studies of cognition in children, and a series of simple but ingenious tests to reveal different cognitive abilities.
The learning theory of cognitive development is a theory in psychology, advanced by Jean Piaget, a Swiss developmental psychologist. At its very basic level, his theory explains the role that the human brain plays in helping learners understand new .

A growing body of scientific evidence demonstrates that emotional development begins early in life and is closely connected with the emergence of cognitive, language and social skills.
