Which of the following is a Piagetian construct in the context of cognitive development of children ?

The correct option is Schemas.

Jean Piaget, a pioneering psychologist in child development, proposed a theory of cognitive development that explains how children construct a mental model of the world around them.

Key Concept: Schemas
According to Piaget, schemas are the basic building blocks of intelligent behavior—mental structures or concepts that help individuals organize, process, and interpret incoming information. As children interact with their environment, they continuously adapt their existing schemas through the processes of assimilation (incorporating new experiences into existing schemas) and accommodation (modifying existing schemas based on new information).

Analysis of Other Options:
• Observational learning: Associated with Albert Bandura's Social Learning Theory.
• Conditioning: Associated with Ivan Pavlov (Classical Conditioning) and B.F. Skinner (Operant Conditioning).
• Reinforcement: A key term in B.F. Skinner's Operant Conditioning framework.

Therefore, Schemas is the correct Piagetian construct in the context of cognitive development.
