Contending with foreign accent in early word learning.

Area of Science:

• Child development
• Linguistics
• Psychology

Background:

• Children aged two begin mapping meaning to form.
• Separating relevant phonemic information from irrelevant details like voice and accent is challenging.
• Little is known about toddlers' ability to ignore irrelevant phonetic details during word learning.

Purpose of the Study:

• To examine the impact of foreign accent on word learning in toddlers.
• To investigate how toddlers aged 2;0 and 2;6 generalize newly learned words presented with different accents.

Main Methods:

• An experiment was conducted with English-learning toddlers.
• Toddlers were trained on new words spoken by a native English speaker and a Spanish-accented speaker.
• Generalization of learned words was tested using both native and accented speakers.

Main Results:

• Toddlers aged 2;6 successfully generalized words regardless of speaker accent.
• Toddlers aged 2;0 failed to generalize words when training and testing accents differed (native to accented).
• Exposure to a foreign accent during training appeared to enhance word generalization.

Conclusions:

• Developmental changes in early word representations influence accent processing.
• Foreign accent exposure during training may facilitate word generalization in young children.
• Toddlers' ability to ignore irrelevant phonetic information develops with age.
