Phonological memory is linked to vocabulary and grammar skills in bilingual children, both within and across languages. These associations were observed in French-English and Spanish-English speakers from 30 to 48 months.
Area of Science:
- Child language acquisition
- Bilingualism research
- Cognitive development
Background:
- Phonological memory plays a crucial role in language learning.
- Understanding cross-linguistic influences is vital for bilingual development.
- Early language skills in bilingual children require further investigation.
Purpose of the Study:
- To examine within-language and between-language links between phonological memory, vocabulary, and grammar.
- To investigate these associations in French-English and Spanish-English bilingual children.
- To determine how these relationships evolve between 30 and 48 months of age.
Main Methods:
- Bilingual children (N=68) aged 30, 36, and 48 months participated.
- Language samples (vocabulary, grammar) were collected during free play.
- Nonword repetition tasks assessed phonological memory in both languages.
- Parent inventories and standardized tests measured vocabulary.
Main Results:
- Phonological memory showed associations with vocabulary and grammar within each language.
- Phonological memory in one language was linked to development in the other language.
- Within-language effects remained stable, while between-language associations varied with age.
Conclusions:
- Findings support the existence of cross-language associations between phonological memory and lexical/grammatical skills.
- Phonological memory is a significant factor in bilingual language development.
- The study highlights the interconnectedness of language skills in young bilinguals.

The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
