Sampling to learn words: Adults and children sample words that reduce referential ambiguity

Area of Science:

• Cognitive Science
• Developmental Psychology
• Linguistics

Background:

• Word learning involves acquiring new vocabulary.
• Learners may strategically select information to reduce uncertainty about word meanings.

Purpose of the Study:

• To investigate whether learners preferentially seek information that reduces referential ambiguity during word learning.
• To examine this strategy in both adults and children across different experimental contexts.

Main Methods:

• Cross-situational word learning tasks with manipulated referential ambiguity.
• Adult and child participants (3-8 years) chose to receive additional training on specific word-object associations.
• Performance was assessed after training.

Main Results:

• Adults preferentially selected ambiguous word-object pairs to reduce referential ambiguity, improving learning.
• Children showed mixed results; initially not preferring ambiguous items, but later favoring them when ambiguity was enhanced.
• This suggests a developing ambiguity-reduction strategy in children's word learning.

Conclusions:

• Learners actively contribute to their own language development by strategically seeking information.
• The ambiguity-reduction strategy plays a role in efficient word learning across different age groups.
• Understanding this active information-seeking process is crucial for language acquisition theories.
