The developmental origins of phonological memory

Area of Science:

• Developmental Psychology
• Linguistics
• Cognitive Science

Background:

• Phonological memory, crucial for repeating novel word strings, has been viewed as a time-limited store.
• An alternative model posits it arises from dynamic sensorimotor processes in speech perception and production.

Purpose of the Study:

• To investigate the developmental trajectory of phonological memory.
• To explore the role of vocal production and sensorimotor experiences in its development.
• To examine cross-linguistic data on phonological memory formation.

Main Methods:

• Longitudinal tracking of phonological memory development from early vocalizations to word consolidation.
• Analysis of data from children acquiring six different languages.
• Connecting early babbling milestones to later lexical advancements.

Main Results:

• Advances in babbling predict phonological memory capacity.
• Phonological memory develops through stages: adult-like vocalizations, first words, and lexical network consolidation.
• Interaction between perceptual and production experiences is key for mapping new forms to lexical representations.

Conclusions:

• Phonological memory is rooted in sensorimotor development and vocal production, not solely a passive store.
• Early vocal experiences significantly influence the development of word learning and memory.
• The findings support an embodied cognition perspective on language acquisition.
