Novel phonotactic learning: Tracking syllable-position and co-occurrence constraints.

Area of Science:

• Psycholinguistics
• Cognitive Science
• Speech Perception

Background:

• Learning novel phonotactics involves understanding permissible sound sequences.
• Previous research has not clarified whether learners simultaneously represent co-occurrence and syllable-level information.

Purpose of the Study:

• To investigate whether adults simultaneously represent syllable-level and co-occurrence information when learning novel phonotactics.
• To determine if sound sequence representations occur at multiple levels.

Main Methods:

• Adult participants were trained on novel word-medial consonant restrictions.
• Recognition tasks tested false recognition of novel items based on consonant co-occurrence and syllable position.
• Experiments manipulated syllable position and co-occurrence information independently.

Main Results:

• Participants falsely recognized novel items with trained co-occurrences more often than those with untrained co-occurrences, indicating tracking of co-occurrence information.
• Participants falsely recognized novel items with trained syllable positions more often than those with untrained syllable positions, indicating tracking of syllable-level information.
• Both co-occurrence and syllable-level information were tracked independently.

Conclusions:

• Adults learning novel phonotactics spontaneously represent sound sequences at multiple levels simultaneously.
• Learners track both co-occurrence patterns and the specific syllable positions of sounds.
• This suggests a robust and multi-faceted representation of speech sound sequences.
