This study explores the omission of the passive participle in passive sentences in simultaneously bilingual children who speak both Mandarin and English. It aims to evaluate whether these children exhibit more features consistent with the Unitary Systems Hypothesis (USH) or the Separate Systems Hypothesis (SSH) in their language production, specifically concerning passive sentence formation. The research analyzes whether the bilinguals' production patterns support the idea that their bilingual language system functions more like a unified system or separate systems for each language.

The experiment involved a passive sentence production task administered to children aged 4-8, divided into groups based on their language acquisition history: simultaneous bilinguals (Mandarin and English learned concurrently), children who learned Mandarin first then English (sequential bilinguals), and monolingual English-speaking children. The objective was to analyze the differences in the omission of the passive participle, which is a key marker in passive sentence construction, across these groups.

Quantitative data analysis involved an ANOVA (Welch’s) test, which revealed a significant main effect (F(2, 5.52) = 13.4, p = 0.008), indicating differences among the groups in passive sentence construction. Pairwise comparisons using Tukey’s post hoc test revealed that the errors in the bilingual groups varied: the errors were not significantly different between the monosyllabic (mono) and simultaneous bilingual groups (mean difference = -1.25, p = 0.193), but there was a significant difference between these groups and the sequential bilingual group (mean difference = -3.75, p

The descriptive statistics indicated that monolingual English children had an error mean of 0.25, with a standard deviation of 0.500, and the simultaneous bilingual group had a mean of 1.50 (SD = 0.577), whereas the sequential group had a higher mean error rate of 4.00 (SD = 1.414). These results suggest that sequential bilinguals are more prone to omit the passive participle than their simultaneously bilingual peers or monolingual children, supporting the notion that early and simultaneous exposure to two languages facilitates more native-like passive constructions.

The findings of this study suggest that simultaneously bilingual children display features akin to the USH, implying their language system operates as a unified system rather than separate ones. This is evidenced by their relatively better performance in passive sentence production compared to sequential bilinguals. Contrary to initial expectations, the data supports the hypothesis that simultaneous bilinguals do not produce passive sentences with as much omission of the passive participle, aligning more with USH predictions. These findings contribute to ongoing debates about the nature of bilingual language processing, indicating that early, simultaneous bilingual exposure fosters a more integrated language system.

In conclusion, the study affirms that bilingual language development, particularly in the context of passive sentence formation, is influenced by the timing of language acquisition. Early and simultaneous exposure to Mandarin and English appears to promote language processing mechanisms similar to those in monolinguals, thus supporting the USH. Conversely, sequential bilinguals tend to show more deviations from typical passive construction, consistent with the idea of separate systems. These insights have implications for language acquisition theories and bilingual education strategies, highlighting the importance of early exposure in developing native-like language processing skills.

Understanding how bilingual children acquire and produce grammatical structures across two languages is a complex avenue of linguistic research. This study investigates whether simultaneous bilingual children—those exposed to Mandarin and English from an early age—display language processing patterns more consistent with the Unitary Systems Hypothesis (USH) or the Separate Systems Hypothesis (SSH). The focus is on the omission of the passive participle in passive sentences, a key grammatical feature in English. The research explores the extent to which early bilingual exposure influences grammatical accuracy, particularly in passive constructions, providing broader insights into bilingual language development theories.

Methodologically, the research employed a passive sentence production task with children aged 4 to 8, categorized into three groups: simultaneous bilinguals, sequential bilinguals (Mandarin first, then English), and monolingual English speakers. The primary measure was the frequency of errors involving omission of the passive participle. The hypothesis posited that early, simultaneous bilinguals would produce passive sentences with fewer errors, indicative of a more integrated, USH-like system, whereas sequential bilinguals might demonstrate more segregation of language systems, resulting in higher omission rates—aligning with the SSH.

Data analysis involved an ANOVA (Welch’s), which found significant differences among groups, indicating variability in the ability to correctly produce passive sentences. Pairwise Tukey post hoc comparisons revealed that the sequential bilingual group exhibited significantly more errors than both the monolingual and simultaneous bilingual groups, with mean differences of −3.75 (p

Descriptive statistics reinforced these findings, with monolingual children showing minimal errors (mean=0.25), and the simultaneous bilinguals demonstrating intermediate error rates (mean=1.50), whereas sequential bilinguals had the highest error rate (mean=4.00). These patterns support the proposition that early bilingual experiences facilitate a more unified grammatical system, as proposed by the USH, leading to more accurate and complete passive sentence constructions.

The implications of these results extend beyond syntactic accuracy, contributing to debates about the cognitive architecture underlying bilingual language processing. The data suggests that early, simultaneous bilingualism fosters integration within the language system, enabling children to produce more native-like grammatical structures such as passive sentences. This aligns with prior research indicating that early bilinguals tend to develop more native-like proficiency across both languages (Kroll & de Groot, 1997; Grosjean, 2010). Conversely, the more segregated language system hypothesis predicts that sequential bilinguals, who learn languages at different times, will show greater grammatical errors, as supported by the higher omission rates observed in this group.

Furthermore, these findings have practical implications for education and language therapy. Early bilingual exposure should be encouraged to support native-like grammatical development, particularly in structures such as the passive voice that are complex and sensitive to language processing constraints. Educators working with bilingual children can tailor teaching strategies to reinforce grammatical structures that are more prone to omission in sequential learners. Clinicians can also leverage these insights to better diagnose and support bilingual children struggling with grammatical errors, emphasizing early exposure interventions.

In conclusion, the study underscores the significance of early, simultaneous bilingual exposure in fostering more integrated and proficient grammatical processing. The data provides strong evidence supporting the USH, illustrating how early exposure influences the development of complex grammatical structures such as the passive voice. Moving forward, longitudinal research could further clarify how these mechanisms evolve over time and how they influence bilingual proficiency in diverse linguistic contexts. Overall, understanding these processes enhances both theoretical models of bilingual language development and practical approaches to supporting bilingual learners.
