Developmental changes in phonological and semantic priming effects in Spanish-speaking toddlers.

Research on the early lexical-semantic system has described how toddlers organize word representations based on semantic and phonological features. This study is a longitudinal investigation of the development of this organization during infancy. Middle-high socioeconomic status Mexican toddlers ( = 28, 15 female) were presented with a preferential looking task using an eye-tracker at 18, 21, and 24 months of age, manipulating semantic and phonological lexical links.
