Question

Quizplus · Accepted Answer

Julia's ability to arrange toys by size and understand the relationship between their sizes (if A > B and B > C, then A > C) demonstrates seriation and transitive inference. Seriation is the ability to sort objects in an order according to one or more dimensions, such as size. Transitive inference is understanding the relationship between two objects by knowing the relationship of each to a third object. This is a skill that typically develops during Piaget's concrete operational stage of cognitive development, which occurs from about 7 to 11 years of age.
