An onset is an onset: Evidence from abstraction of newly-learned phonotactic constraints

•Adults were trained and tested in a continuous recognition memory task.•They rapidly learned novel consonant-position constraints (phonotactics).•Learning generalized to novel word structures and novel word positions.•Similar learning and generalization found for word-medial and word-edge constraints.•Results suggest syllable-level representations for phonotactic learning.

Phonotactic constraints are language-specific patterns in the sequencing of speech sounds. Are these constraints represented at the syllable level (ng cannot begin syllables in English) or at the word level (ng cannot begin words)? In a continuous recognition-memory task, participants more often falsely recognized novel test items that followed than violated the training constraints, whether training and test items matched in word structure (one or two syllables) or position of restricted consonants (word-edge or word-medial position). E.g., learning that ps are onsets and fs codas, participants generalized from pef (one syllable) to putvif (two syllables), and from putvif (word-edge positions) to bufpak (word-medial positions). These results suggest that newly-learned phonotactic constraints are represented at the syllable level. The syllable is a representational unit available and spontaneously used when learning speech-sound constraints. In the current experiments, an onset is an onset and a coda a coda, regardless of word structure or word position.
