The original version of this article was published with an error in the abstract. The published version began “Language development requires children to learn how to understand ambiguous pronouns, as in Panda Bear is having lunch with Puppy. He wants a pepperoni slice. Adults tend to link he with Puppy, the prior grammatical subject, ….”

This should really say “Adults tend to link he with Panda Bear” (not Puppy), since Panda Bear is the grammatical subject. This example is described throughout the paper, and elsewhere it is correct, but unfortunately the wrong name was used in the abstract.

This has now been corrected in the original published version.
