What is intersubjectivity in Vygotsky's theory?

• A. Shared understanding among participants in an activity
• B. Private speech used for self-regulation
• C. Recall enhanced memory
• D. Observation without social interaction

Answer: (A)

Intersubjectivity is the shared, common understanding that people develop together through social interaction. In Vygotsky’s view, cognitive development begins in the social world as individuals talk, gesture, and attend to the same aspects of a task. Through this collaborative engagement, they negotiate meaning and align their perspectives, creating a unified interpretation that guides action. This shared understanding lays the groundwork for joint problem solving and is eventually internalized as independent knowledge. It isn’t about private self-talk or isolated recall; it requires others and a setting that supports collaboration.
