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 (n = 28, 15 female) were presented with a…

Linguistic alignment--the contingent reuse of our interlocutors' language at all levels of linguistic structure--pervades human dialogue. Here, we design unique measures to capture the degree of linguistic alignment between interlocutors' linguistic representations at three levels of structure: lexical, syntactic, and semantic. We track these…

This study examines semantic development in 60 Spanish-English bilingual children, ages 7 years 3 months to 9 years 11 months, who differed orthogonally in age (younger, older) and language experience (higher English experience [HEE], higher Spanish experience [HSE]). Children produced 3 associations to 12 pairs of translation equivalents. Older…

The Deese/Roediger-McDermott (DRM) paradigm was used to investigate developmental trends in accurate and false memory production. In Experiment 1, DRM lists adjusted to be more consistent with children's vocabulary were used with 2nd graders, 8th graders, and college students. Accurate and false recall and recognition increased with age, but…

Background: Children who have reached the age of 2 years without having acquired a 50-word vocabulary and/or who use no word combinations are referred to in the literature as "Late Talkers". Research has not yet identified the factors that cause slow development of expressive language; in particular, relatively little research has been carried out…
