COGNITIVE DEVELOPMENT


COGNITIVE DEVELOPMENT

Development

Development refers to the changes which takes place in human being or animals from its creation to death. Development can be classified into physical development, personal development, social development and cognitive development. People develop at their own pace as they have different rates of development. Development occurs in  a logical order, this it takes place gradually.

Piaget's Theory of Cognitive Development

Certain ways of thinking that are quit simple for an adult are not simple for a child, Piaget (1954). As per his theory maturation is unfolding of biological changes that are genetically programmed. So the social interactions have a very little impact on a person's cognitive development.

Thinking

As per Piaget all the species inherit two basic tenancies. They are:
  1. Organization
  2. Adaptation
According to his theory, thinking is based on schemes, which is mental system or categories of perception and experience.
Adaptation
Adaptation includes both assimilation and accommodation
Ø  Assimilation takes place when people fit their new information into existing schemes, to make sense out of it.
Ø  Accommodation takes place when existing schemes are altered to response new information as data cannot be fit into the existing schemes.
Equilibration
According to Piaget actual changes in thinking takes place through equilibration – Search for mental balance between cognitive schemes and information from the environment.

Four Stages of Cognitive Development

1. The Sensimotor Stage
ü  0-2 years
ü  Child's thinking involves seeing, moving, touching, tasting, and so on
ü  Infant develops object permanence – The understanding that objects have a separate, permanent existence
ü  Begin logical goal-directed actions – Deliberate actions towards a goal

2. The Preparational Stage
ü  2-7 years
ü  Make action schemes symbolic, develops ability to think in symbolic form
ü  Able to think about operations only in one direction
ü  Have tenancy to be egocentric – assuming that others experience the world same way as you do. So they have difficulty in understanding others view point.
3. The Concrete-Operational Stage
ü  7-11 years
ü  Recognition of the logical stability, the realization that elements can be changed and still conserve many of its original characteristics
ü  Master classification and reversibility – think about series of steps and reverse them
4. Formal Operations
ü  Focus of thinking can change from “what is” to “what might be”
ü  Includes hypothetico-deductive reasoning – Begins by identifying all the factors that might affect a problem and then deduce and systematically evaluates specific solutions.
ü  Includes inductive reasoning – Using specific observations to identify general principles
ü  Develops concern about social issues, identity

Limitations of Piaget's Theory

  1. The trouble with stages:
û  Lack of consistency in children's thinking
û  Process maybe continuous than they seem

  1. Underestimate children's ability
û  Underestimated cognitive ability of children
û  Does not explain how even young children can perform at an advanced level

  1. Cognitive development and culture
Overlooks the important effects of the child's culture and social group
