The findings for adverbs and adverbial phrases in a naturalistic corpus of Miami Haitian Creole–English code-switching show that one language, Haitian Creole, asymmetrically supplies the grammatical frame while the other language, English, asymmetrically supplies mixed lexical categories like adverbs. Traces of code-switching with an English frame and Haitian Creole lexical categories suggest that code-switching is abstractly BIDIRECTIONAL. A quantitative methodology that codes the language-indexation of the token in addition to the surrounding lexical items was used for all mixed (e.g. xYx/yXy, xYy/yXx, yYx/xXy) and unmixed (xXx/yYy) adverbs. Discourse position, especially the left-periphery, is found to be a significant factor in adverb code-switching. Sociolinguistic and psycholinguistic analyses which acknowledge the ‘low’ status of one language and the ‘high’ status of the other explain better the frequency of mixed English adverbs in a Haitian Creole frame and the rarity of mixed Haitian Creole adverbs in an English frame than a minimalist approach, such as MacSwan's (1999 and subsequent work), which uses phi-feature valuation and entails asymmetry without bidirectionality. While I provide confirmation for Myers-Scotton's (1993) Matrix Language Frame approach, I emphasize that trace bidirectional data need to be accounted for by a theory that is grounded in the sociolinguistic and psycholinguistic realities.

Studies often report that bilingual participants possess a smaller vocabulary in the language of testing than monolinguals, especially in research with children. However, each study is based on a small sample so it is difficult to determine whether the vocabulary difference is due to sampling error. We report the results of an analysis of 1,738 children between 3 and 10 years old and demonstrate a consistent difference in receptive vocabulary between the two groups. Two preliminary analyses suggest that this difference does not change with different language pairs and is largely confined to words relevant to a home context rather than a school context.

This study investigates the role of transfer from the stronger language by focusing on the interpretation of definite articles in Spanish and English by Spanish heritage speakers (i.e., minority language-speaking bilinguals) residing in the U.S., where English is the majority language. Spanish plural NPs with definite articles can express generic reference (Los elefantes tienen colmillos de marfil), or specific reference (Los elefantes de este zoológico son marrones). English plurals with definite articles can only have specific reference (The elephants in this zoo are brown), while generic reference is expressed with bare plural NPs (Elephants have ivory tusks). Furthermore, the Spanish definite article is preferred in inalienable possession constructions (Pedro levantó la mano “Peter raised the hand”), whereas in English the use of a definite article typically means that the body part belongs to somebody else (alienable possession). Twenty-three adult Spanish heritage speakers completed three tasks in Spanish (acceptability judgment, truth-value judgment, and picture–sentence matching tasks) and the same three tasks in English. Results show that the Spanish heritage speakers exhibited transfer from English into Spanish with the interpretation of definite articles in generic but not in inalienable possession contexts. Implications of this finding for the field of heritage language research and for theories of article semantics are discussed.

This paper investigates how syntactic knowledge interfaces with other cognitive systems by analysing the production of postverbal subjects, V(erb)–S(ubject) order, in an L1 Spanish–L2 English corpus and a comparable English native corpus. VS order in both native and L2 English is shown to be constrained by properties operating at three interfaces: (i) lexicon–syntax: the verb is unaccusative (Unaccusative Hypothesis); (ii) syntax–discourse: the subject is focus (End-Focus Principle) and (iii) syntax–phonology: the subject is heavy (End-Weight Principle). We show that, since learners produce VS under the same interface conditions as native speakers, unaccusativity is a necessary but not a sufficient condition for VS production. However, learners overproduce VS and make persistent errors in their syntactic encoding. Our findings support recent proposals that these difficulties stem from problems at coordinating syntactic knowledge with knowledge from other external systems, but they suggest that the nature of such difficulties is not external to the syntax.

This study investigated the encoding strategies employed by Chinese and English language users when recalling sequences of pictured objects. The working memory performance of native English participants (n = 14) and Chinese speakers of English as a second language (Chinese ESL; n = 14) was compared using serial recall of visually-presented pictures of familiar objects with three conditions: (i) phonologically and visually distinct, (ii) phonologically similar and visually distinct, and (iii) phonologically distinct and visually similar. Digit span, visual pattern span and articulation rate were also measured. Results indicated that whilst English participants were affected by the phonological but not the visual similarity of items, the performance of Chinese ESL participants was comparable across all three conditions. No significant differences in digit span, visual memory or articulation rate were found between groups. These results are discussed in the light of our understanding of the use of cognitive resources in short-term memory in users of diverse orthographies.

This study examines L1–L2 interaction in semantic categorization in early and late L2 learners. Word categories that overlapped but were not identical in Arabic and English were tested. Words always showed a ‘wider’ range of application in one language, ‘narrower’ in the other. Three types of categories – ‘classical’, ‘radial’, and ‘homophones’ – were examined. Monolingual Arabic, monolingual English, early bilingual, and late bilingual speakers were tested for their understanding of the Arabic or English words. Early bilinguals’ semantic structure is affected in both directions, late bilinguals’ only in the direction of L1 to L2. Classical categories were most vulnerable to inter-language influence, whereas homophones were least vulnerable. The discussion addresses a developmental model of semantic interaction in early and late bilingual learners.

The present study investigates the syntactic competence of bilingual Portuguese–German returnees who have lost regular contact with their L2 (German). The main criterion which distinguishes the participants is the age of input loss. This allows their division into two main groups: speakers who lost German input during early childhood (between ages seven and ten) and speakers who were eleven or older when they moved away from the German environment. Focusing on verb placement in main and embedded clauses, the available data show strong evidence of the existence of a stabilization phase following the acquisition period. The speakers who lost L2 input earlier than age eleven show significantly more syntactic deficits than the other speakers. However, the observed attrition effects seem to be the result of insufficient L2 activation, rather than the expression of undergoing competence loss.

This paper explores whether the poor mastery of morphosyntax exhibited by second language (L2) learners can be tied to difficulties with non-syntactic processing. Specifically, we examine whether problems with English regular and irregular past tense are related to poor L2 phonological ability and lexical access, respectively. In Experiment 1, L2 learners showed poorer past tense mastery than native English speakers in grammaticality judgment and production tasks. L2 phonological ability was positively correlated with correct performance on regular verbs and negatively with unmarked production. L2 lexical access was positively correlated with correct performance on irregular verbs, and negatively with overregularization production. Experiment 2 simulated these difficulties in native English speakers by placing them under phonological processing (noise) or lexical access (deadline) stress. Noise selectively impacted regular verbs in grammaticality judgment but impacted all verb types in production. Deadline pressure impacted irregular verbs while sparing regular verbs across both tasks. Thus, non-syntactic processing difficulties can have specific impacts on morphosyntactic performance in both non-native and native English speakers.

Previous language learning research reveals that the statistical properties of the input offer sufficient information to allow listeners to segment words from fluent speech in an artificial language. The current pair of studies uses a natural language to test the ecological validity of these findings and to determine whether a listener's language background influences this process. In Study 1, the “guessibility” of potential test words from the Norwegian language was presented to 22 listeners who were asked to differentiate between true words and nonwords. In Study 2, 22 adults who spoke one of 12 different primary languages learned to segment words from continuous speech in an implicit language learning paradigm. The task consisted of two sessions, approximately three weeks apart, each requiring participants to listen to 7.2 minutes of Norwegian sentences followed by a series of bisyllabic test items presented in isolation. The participants differentially accepted the Norwegian words and Norwegian-like nonwords in both test sessions, demonstrating the capability to segment true words from running speech. The results were consistent across three broadly-defined language groups, despite differences in participants’ language background.
