Children begin to use symbols, like words and images, representing objects and ideas. Developing language and pretend play.
A child's thinking is egocentric. Children are not able to take the perspective of other. They believe that everyone sees, thinks and feels the same way they do.
Conservation errors are made during this stage. Children think that by pouring liquid from a smaller, shorter glass to a taller, thinner glass. The taller glass will have more.
Children think more logically and rationally
Are able to apply rules in a logical way
Children develop skills like conservation, reversibility, and classification
Children/teenagers learn logical rules during this stage
Allowing them to understand abstract concepts and solve problems
Conservation: A logical thinking ability that allows a person to determine that a certain quantity will remain the same even when changed into a different container, shape or size.
Reversibility: The ability to understand that things can be changed and then changed back to their original state. Ex: 2+3=5 and 5-3=2
Classification: The process of grouping objects, ideas and events based on the characteristics that they share. Ex: characterizing objects by colors or shapes.
