Stage of development
Case study supporting stage
Piaget believes that from birth to about 2 years is a period of rapid intellectual development.
During this stage children use ‘trial and error’ in order to learn. Prior to the trial and error stage, children would normally depend on their reflexes.
Extreme egocentrism is what children are characterised as at this stage. Piaget says at this stage children have no understanding of the world other than their own.
Piaget believes at this stage children are able to realise that an object still exist even if their vision of the object is obscured. This is called ‘Object Permanence’. However, children develop this from the age of 8 months based on the findings of his ‘blanket and ball’ experiment. Blanket and ball (Piaget 1968)
Piaget devised an experiment to support his theory of the sensorimotor stage. (Object Permanence)
Method: He would hide a toy under a blanket while the child watches him do it. He wanted to see whether the child searches for the hidden toy or not.
Result: he found that infants searches for the hidden toy when they were around 8-months-old. Preoperational
Piaget believes that Egocentrism is still very present at this stage of the child’s development.
During this stage children begin to display ‘Animism’. This means that they incapable of realising that inanimate objects do not have human capabilities (e.g. feelings)
Three mountains Task (Piaget and Inhelder 1956)
Piaget devised an experiment to find out the age in which children decenter
Method: The child sits at a table, presented in front are three mountains. The mountains were different, with snow on top of one, a hut on another and a red cross on top of the other. The child was allowed to walk round the model, to look at it, and then sit down at one side. A doll is then placed at various positions of the table. The child is then shown 10 photographs of...
