Young children use shared experience to interpret definite reference.

Area of Science:

• Developmental psychology
• Linguistic development
• Cognitive science

Background:

• Understanding referential communication is crucial for language acquisition.
• Children's ability to grasp shared knowledge (common ground) influences their interpretation of language.
• The role of articles (definite vs. indefinite) in signaling common ground is not fully understood in early childhood.

Purpose of the Study:

• To investigate if two- and three-year-old children comprehend that the definite article ('the') signals a referent within shared common ground.
• To determine if children use joint experiences to interpret a speaker's referential intent.

Main Methods:

• An experiment involved an experimenter and a child engaging in joint actions with objects.
• The experimenter selected one of three similar objects for a shared action.
• Children were subsequently asked to retrieve either 'the X' (definite article) or 'a X' (indefinite article).

Main Results:

• Children significantly preferred the shared object when instructed with the definite article ('the X').
• When instructed with the indefinite article ('a X'), children's choices were at chance, indicating they did not rely on shared experience.
• This suggests children in their third year utilize shared experiences to interpret referential choices.

Conclusions:

• Three-year-old children can interpret the definite article as signaling a referent within common ground.
• Joint action plays a vital role in establishing common ground, aiding children's understanding of referential language.
• These findings contribute to understanding children's developing representation of linguistic categories and pragmatic competence.
