Cognitive Development - Stage 4 - Formal Operational

During the Formal Operational stage children develop their capacity of deductive logic. This means that problem solving is not limited to concrete thinking (present objects). This video shows how children at this stage are able to engage in abstract thinking.

Cognitive Development - Stage 1 - Sensorimotor

This video shows how children are in their way of developing object permanence, which refers to the ability to understand that things exist even when you are not looking at them. The development of object permanence occurs during the Sensorimotor stage.

Cognitive Development - Stage 3 - Concrete Operational

This video shows how the ability of conservation is completed. This occurs during the Concrete Operational stage. During this stage, children also develop their capacity of inductive logic, which refers to the ability to use their schemata and previous experiences for problem solving.

Cognitive Development - Stage 2 - Preoperational

The conservation task is part of the experiments developed to demonstrate the Piagetian stages of coginitive development. During the Preoperational stage children are not able to perceive conservation, which refers to object alteration of place or spatial organization (among others) without affecting quantity, volume, weight and other physical characteristics.
