Phonological Learning Influences Label-Object Mapping in Toddlers.

Area of Science:

• Developmental Psychology
• Linguistics
• Cognitive Science

Background:

• Infants naturally learn native language sound patterns.
• Phonological knowledge aids new word acquisition.
• The impact of emerging phonological regularities on word learning is unclear.

Purpose of the Study:

• To investigate if learning a new phonological pattern affects subsequent novel word learning in toddlers.
• To examine the role of developing phonological knowledge in early word acquisition.

Main Methods:

• Familiarized 41 two-year-olds with novel words following a specific phonotactic regularity.
• Taught toddlers novel label-object pairs, with some labels consistent and others inconsistent with the learned regularity.

Main Results:

• Toddlers with smaller vocabularies learned all novel word pairings.
• Toddlers with larger vocabularies selectively learned pairings consistent with the novel phonological pattern.

Conclusions:

• Newly acquired phonological patterns influence toddlers' novel word learning.
• Individual differences in vocabulary size correlate with how toddlers utilize emerging phonological knowledge for word learning.
