What's new? Children prefer novelty in referent selection

Area of Science:

• Developmental Psychology
• Child Language Acquisition
• Cognitive Science

Background:

• Children learning new words must map novel names to referents.
• Existing research focuses on external information sources (linguistic, contextual, pragmatic).
• The role of internal biases, like novelty preference, is less understood.

Purpose of the Study:

• To investigate how children's familiarity with objects and their bias for novelty affect referent selection.
• To explore endogenous factors influencing early word learning.

Main Methods:

• Two experiments were conducted with 2-year-old children.
• Children were familiarized with novel objects.
• Referent selection was tested using novel names and objects varying in novelty and prior exposure.

Main Results:

• Children consistently selected the most novel object when mapping a new name.
• This bias persisted even when children had prior exposure to some objects.
• A second experiment confirmed this finding, controlling for pragmatic factors.

Conclusions:

• Children's referent selection is significantly influenced by their prior exposure to objects.
• An endogenous bias towards novelty plays a critical role in early word learning.
• Understanding these internal biases is key to comprehending language acquisition processes.
