Novel phonotactic learning by children and infants: Generalizing syllable-position but not co-occurrence regularities

Area of Science:

• Developmental Psychology
• Linguistics
• Cognitive Science

Background:

• Phonotactic constraints govern sound sequencing in language.
• These constraints can operate at the level of sound co-occurrences or syllable positions.

Purpose of the Study:

• To investigate whether 5-year-old children and 11-month-old infants can represent phonotactic constraints based on sound co-occurrences and/or syllable positions.
• To determine which type of phonotactic information is more readily generalized by young learners.

Main Methods:

• Participants (children and infants) were exposed to artificial languages with specific consonant restrictions.
• Restrictions involved both word-medial consonant co-occurrence pairs (e.g., FP allowed, FZ not) and consonant placement within syllables (e.g., P as onset, F as coda).
• Behavioral responses (children's familiarity judgments, infants' orientation times) were measured for novel words violating or adhering to these constraints.

Main Results:

• Children showed similar generalization for co-occurrence constraints but were more influenced by syllable-position constraints.
• Infants exhibited similar attention to novel words regardless of co-occurrence constraint violations but showed longer attention for syllable-position violations.
• Both age groups demonstrated greater generalization of syllable-position information compared to consonant co-occurrence information.

Conclusions:

• Syllable-position information appears more accessible for spontaneous representation and generalization in infants and children than consonant co-occurrence information.
• When multiple phonotactic regularities are present, syllable position constraints may be prioritized in early language learning.
• Findings contribute to understanding the developmental trajectory of phonotactic constraint representation in young children and infants.
