Summary
Infants as young as 16.5 months can quickly learn new sound patterns (phonotactic regularities) not found in English. They demonstrated this by preferring novel syllables that followed learned rules over those that broke them.
Area of Science:
- Psycholinguistics
- Developmental Psychology
- Speech Perception
Background:
- Infants' ability to learn language-specific sound patterns is crucial for language acquisition.
- Previous research suggests infants are sensitive to phonotactic probabilities in their native language.
Purpose of the Study:
- To investigate if 16.5-month-old infants can acquire novel phonotactic regularities absent in English.
- To determine if infants can generalize learned phonotactic rules to new, unstudied syllables.
Main Methods:
- Two experiments using consonant-vowel-consonant syllables with artificial phonotactic constraints.
- Infants were exposed to these constrained syllables.
- A head-turn preference test was used to measure listening times to novel syllables violating or honoring the learned constraints.
Main Results:
- Infants listened significantly longer to new syllables that violated the experimental phonotactic constraints.
- This indicates infants learned and recognized the novel sound patterns.
Conclusions:
- 16.5-month-old infants can rapidly learn abstract phonotactic regularities from limited auditory exposure.
- Infants demonstrate the ability to generalize these learned rules to unfamiliar words, highlighting early language processing sensitivities.
