• No long-distance zibun in child-directed speech.
Learning long-distance zibun requires
projecting beyond the input.

Value Judgment task
• TVJT: A puppet makes a statement about a story. A child’s task is to reward or
correct the puppet based on the statement.
• Previous studies: Children allow the long-distance zibun interpretation.
- Otsu (1990): disproportional salience of potential antecedents (zibun’s picture)
- Okabe (2008): failure to satisfy Condition of Plausible Dissent (Crain & Thornton 1998)

Two possibilities
• zibun is local-only
• unable to access the matrix subject
→ To distinguish these possibilities,
we ran a kare condition.

Discussion
Summary
Children incorrectly rejected the
long-distance antecedent for
zibun, despite being able to
access this antecedent for kare.
Children’s knowledge of zibun
• Local-only?
• Ambiguity resolution difficulty?
