MINE! That word appears early in life. ___1___ do have an idea of ownership.
They also have an idea of what can be owned, and what can’t.

Children as young as three believe human-made objects are owned but naturally occurring things like pinecones are not.

In one experiment 3-year olds looked at pictures of a fork, teddy bear, truck, and other human-made objects. They also looked at pictures of a leaf, shell, or rock. The researchers asked: Does this belong to anyone?

The kids ___2___ human-made objects as owned 89 percent of the time and naturally occurring objects as owned only 28 percent of the time.

In another experiment scientists tested children with less familiar objects like a ___3___ versus coral. This time children under 6 did not tend to name the manufactured object as owned. But when the unfamiliar, artificial objects were referred to as “human-made,” the younger children tended to classify them as owned. The work appears in the journal Developmental Psychology.

It is apparently only much later in life, when individuals have reached a ___4___maturity, that they can ___5___ of ownership of natural objects. “You kids get off of MY lawn!”
