In this article the triggering hypothesis for codeswitching proposed by Michael Clyne is discussed and tested. According to this hypothesis, cognates can facilitate codeswitching of directly preceding or following words. It is argued that the triggering hypothesis in its original form is incompatible with language production models, as it assumes that language choice takes place at the surface structure of utterances, while in bilingual production models language choice takes place along with lemma selection. An adjusted version of the triggering hypothesis is proposed in which triggering takes place during lemma selection and the scope of triggering is extended to basic units in language production. Data from a Dutch–Moroccan Arabic corpus are used for a statistical test of the original and the adjusted triggering theory. The codeswitching patterns found in the data support part of the original triggering hypothesis, but they are best explained by the adjusted triggering theory.

One hypothesis holds that bilingual children's cross-linguistic transfer occurs in spontaneous production when there is structural overlap between the two languages and ambiguity in at least one language (Döpke, 1998; Hulk and Müller, 2000). This study tested whether overlap/ambiguity of adjective–noun strings in English and French predicted transfer. In English, there is only one order (adjective–noun) while in French both adjective–noun and noun–adjective order are allowed, with the latter as the default. Unidirectional transfer from English to French was predicted. 35 French–English preschool bilingual children (and 35 age-matched English monolinguals and 10 French monolinguals) were asked to name pictures by using an adjective–noun string. In addition to the reversing adjective–noun strings in French as predicted by the overlap/ambiguity hypothesis, the bilingual children reversed more adjective–noun strings in English than monolinguals. It is proposed that cross-linguistic transfer might better be understood as an epiphenomenon of speech production.

This study examines growth rates in vocabulary over an academic year for 150 Latino English language learners. In October, February, and June of kindergarten, participants completed standardized measures of receptive and expressive vocabulary. Before the second and third assessments, a third of the children watched Arthur three times a week during school hours, while another third viewed Between the Lions. The last third did not view either show during school hours. Data on children's preschool experiences and home literacy activities were collected. Growth modeling analyses show while there were no effects of classroom viewing, children who viewed Arthur and Between the Lions at home had steeper growth trajectories than those who had not. Additional effects of native language home use and preschool attendance were seen. Boys displayed better English vocabulary skills than girls. These findings suggest the importance of English exposure and native language maintenance for English L2 vocabulary development.

This study examined sentence processing in emergent bilingual children and young adults in both English (second language – L2) and Spanish (first language – L1). One hundred participants from five different age groups (5;4–7;11, 8;0–10;11, 11;2–13;11, 14;0–16;8 years, and college-age adults) participated in this study. An online sentence interpretation paradigm was used to explore participants' processing patterns. Results of both choice and reaction time experiments provide new information about consolidation and “in between” strategies for Spanish–English bilinguals; on the use of the distribution of local vs. topological cues (namely early reliance on word order in both languages, followed by an integration of late-emerging subject-verb agreement cues from 11 to 13 years of age). The nature of these syntactic strategies and their implications for developmental theories of bilingualism are discussed.

The degree to which native and non-native readers interpret English sentences incrementally was investigated by examining plausibility effects on reanalysis processes. Experiment 1 required participants to read sentences word by word and to make on-line plausibility judgements. The results showed that natives and non-natives immediately computed the plausibility of the preferred structural analysis, which then affected ease of reanalysis. Experiment 2 required participants to read the same sentences word by word in order to perform a memory task. The natives showed a similar pattern of results to Experiment 1, whereas for the non-natives plausibility effects were delayed. However, the non-natives still appeared to be performing immediate syntactic reanalysis. It is concluded that syntactic processing was person- and task-independent, whereas the incrementality of interpretation was more dependent on task demands for the non-natives than for the natives.

Research investigating the relationship between language and cognition (Lucy, 1992b) shows that speakers of languages with grammatical number marking (e.g. English) judge differences in the number of countable objects as more significant than differences in the number or amount of non-countable substances. On the other hand, speakers of languages which lack grammatical number marking (e.g. Yucatec) show no such preference. The current paper extends Lucy's (1992b) investigation, comparing monolingual English and Japanese speakers with Japanese speakers of English as a second language (L2). Like Yucatec, Japanese is a non-plural-marking language. Results show that intermediate L2 speakers behave similarly to the Japanese monolinguals while advanced L2 speakers behave similarly to the English monolinguals. The results (a) provide support for the claim that grammatical representation may influence cognition in specific ways and (b) suggest that L2 acquisition may alter cognitive dispositions established by a first language (L1).

This study investigated acoustic-phonetics of coronal stop production by adult simultaneous bilingual and monolingual speakers of Canadian English (CE) and Canadian French (CF). Differences in the phonetics of CF and CE include voicing and place of articulation distinctions. CE has a two-way voicing distinction (in syllable initial position) contrasting short-and long-lag VOT; coronal stops in CE are described as alveolar. CF also has a two-way voicing distinction, but contrasting lead and short-lag VOT; coronal stops in CF are described as dental. Acoustic analyses of stop consonants for both VOT and dental/alveolar place of articulation are reported. Results indicate that simultaneous bilingual as well as monolingual adults produce language-specific differences, albeit not in the same way, across CF and CE for voicing and place. Similarities and differences between simultaneous bilingual and monolingual adults are discussed to address phonological organization in simultaneous bilingual adults.
