The results from this study indicate that transfer, deceleration, and a possible variation of the acceleration hypothesis occur in bilingual phonological acquisition. Evidence was found for separation and interaction between the bilingual children's 2 languages (J. Paradis & F. Genesee, 1996).

Purpose In this study, the authors investigated factors that affect bilingual children’s vocabulary and story recall abilities in their 2 languages. Method Participants included 191 Latino families and their children, who averaged 59 months of age. Data on parental characteristics and children’s exposure to and usage of Spanish and English were collected. The authors assessed children’s Spanish and English vocabulary and story recall abilities using subtests of the Woodcock–Muñoz Language Survey—Revised (Woodcock, Muñoz-Sandoval, Ruef, & Alvarado, 2005). Results Sizeable percentages of variation in children’s English (R2 = .61) and Spanish (R2 = .55) vocabulary scores were explained by children’s exposure to, and usage of, each language and maternal characteristics. Similarly, variations in children’s story recall scores in English (R2 = .38) and Spanish (R2 = .19) were also explained by the factors considered in this investigation. However, the authors found that different sets of factors in each category affected children’s vocabulary and story recall abilities in each language. Conclusions Children’s exposure to and usage of their two languages as well as maternal characteristics play significant roles in bilingual individuals’ language development. The results highlight the importance of gathering detailed sociolinguistic information about bilingual children when these children are involved in research and when they enter the educational system.

The preliminary findings suggest that the phonological system of bilingual (Spanish-English) children is both similar to and different from that of monolingual speakers of either language. Compared to monolingual speakers, bilingual children should be expected to exhibit different types of errors and different substitution patterns for target sounds.

Results from this study indicate no link between parent estimates of language output and phonological skill and demonstrate that Spanish-English bilingual children will have commensurate, although not identical, phonological skills as compared to age-matched PS and PE children.

The present study examines the phonological skills of bilingual children, taking language use and proficiency into consideration, and compares their skills to monolingual peers. The main research question is whether bilingual children who have parent-reported language use and proficiency measures commensurate with those of their monolingual peers have phonological skills comparable to their monolingual peers. METHOD. Thirty typically developing Spanish- and English-speaking children participated in this study who were matched on age and language use and proficiency (10 monolingual English, mean age: 5;10; 10 monolingual Spanish, mean age: 5;10, and 10 bilingual, mean age: 6;0). The independent variable was language status (bilingual versus monolingual), and the dependent measures included phonological whole-word measures, segmental accuracy measures, and phonological patterns. RESULTS. Bilingual children did not differ from their monolingual peers on any of the Spanish measures, except on accuracy for stops, on which the monolinguals outperformed their bilingual peers. However, bilingual children outperformed their monolingual English-speaking peers on Proximity, PVC, PCC-R, and PCC for nasals. Moreover, bilingual children displayed lower frequencies-of-occurrence on phonological patterns than their English-speaking monolingual peers: weak syllable deletion, spirantization, and fronting. DISCUSSION. The findings of our study indicate that bilingual children may have an advantage over their monolingual peers when it comes to select phonological skills when language use and proficiency are controlled for.
