Word Learning in Bilingual Children
This study aims to understand how bilingual toddlers learn new words, focusing on how different types of word categories and parent language influence this process. Researchers will compare typically developing bilingual toddlers with those who are late talkers to see if they learn words in similar ways. You might be eligible if your child is between 24 and 30 months old and has exposure to both English and Spanish, or English and another language. The study will look at how children learn words from "Large Semantic Category Conditions" (like animals) and "Small Semantic Category Conditions" (like clothing). Success will be measured by how many words children learn, the properties of their vocabulary, and the language input from parents. The current status of the study is unclear, but it plans to enroll 80 children.
- Study design

What this trial measures
- Word learningDay 1
The researchers will assess learning through participants' looking behavior via experimental eye-tracking paradigms. Specifically, the researchers will measure how accurately and quickly participants look to the target object after hearing its name.
- Vocabulary Network PropertiesDay 1
The researchers will characterize participants' vocabulary size and structure using the MacArthur-Bates Communicative Development Inventories (MB-CDI). Vocabulary size will be calculated using the raw number of words produced (range: 0-680 words) and their age-matched percentile score from the MB-CDI (range: 0-100). Higher scores indicate larger vocabulary sizes.The researchers will also calculate how many words each participant knows in in two categories on the MB-CDI (i.e., animals \[0-43 words\] and tools \[0-28 words\]) across the languages they are learning (i.e., English and Spanish). Network properties may include the number of words in a category and the number of connections between words in a category.
- Parent Language InputDay 1
The researchers will calculate the number of words the parent says to their child during book reading and toy play activities. Language input will be defined as the total number of nouns and verbs (tokens) and the number of unique nouns and verbs (types).
