At what age do self-interest and selectivity begin to inhibit a child's universal impulse to share?

• A. Two years
• B. Three years
• C. Four years
• D. Five years

Answer: (A)

Around this age, children start balancing their natural urge to share with personal wants and ownership. By about two years old, toddlers begin labeling objects as mine and become more aware of keeping what they have, which introduces self-interest into sharing. This shift means their impulse to share is no longer universal; they share more selectively, often influenced by who they know, whether the other person can reciprocate, or whether giving up something would feel like a loss to them. You might see a toddler happily handing over a toy to a familiar peer who has shared with them before, but hesitating or refusing when sharing with a stranger or when it would mean losing a preferred item. That emergence of ownership and reciprocity expectations at around two years is why this age is identified as the point where self-interest begins to inhibit universal sharing.
