Word order and information status in child language

Area of Science:

• Linguistics
• Developmental Psychology
• Cognitive Science

Background:

• Adult language production follows information status, ordering accessible (old) information before inaccessible (new) information.
• Children's early word combinations often mirror input-specific patterns, suggesting limited inherent ordering biases.

Purpose of the Study:

• To investigate whether young children utilize information status for constituent ordering at the phrasal level.
• To determine if children's ordering preferences align with or diverge from adult patterns.

Main Methods:

• Study 1: Examined ordering preferences for "old" versus "new" referents in 3- to 5-year-old children.
• Study 2: Analyzed caregiver speech patterns to assess input influence on children's ordering.

Main Results:

• Children aged 3-5 years demonstrated a preference for ordering new referents before old referents.
• This new-to-old preference in children contrasts with the established old-to-new pattern observed in adults.
• Caregiver speech also predominantly followed the old-to-new pattern, indicating children's preference is not input-driven.

Conclusions:

• The principle of ordering information by accessibility (old-before-new) is not innate but develops over time.
• Early childhood language development involves a shift in ordering preferences from new-to-old to old-to-new.
