Seriation Definition | Psychology

Seriation is the ability to sort objects and events according to a characteristic like color or sound or shape. The third stage of Piaget’s theory of cognitive development is called the concrete operational stage. This stage is from ages 7 to 12 and marks a child’s increased logic and reasoning. This is where seriation occurs.

For example, a child be able to sort different objects by height or size if given the choice. Or to sort hamburgers from most delicious all the way down to McDonald’s attempt at culinary garbage.
