Linguistic Approaches to Bilingualism - Volume 4, Issue 1, 2014

This study examines argument structure overgeneralizations among heritage speakers of Spanish who exhibit varying degrees of proficiency in the heritage language. Two questions motivated the design of the study: (1) Do heritage speakers differ from native speakers in their acceptance of causative errors? And if so, (2) which classes of verbs are most susceptible to this overgeneralization? A sentence acceptability task targeting two verb classes (unaccusatives and unergatives) was administered to 58 heritage speakers and a comparison group (n = 22) of monolingually-raised native speakers of Spanish. The results confirm that heritage speakers, in contrast to native speakers, accept causative errors with a variety of intransitive verbs. Unaccusative verbs are more readily accepted in transitive frames than unergatives for all groups. Acceptance rates for individual verbs are a function of the particular verb’s compatibility with external causation as well as the possibility of being transitive in English.

It is still largely unknown how the two phonological systems of bilingual children interact. In this exploratory study, we examine children’s use of dialect features to determine how their speech sound systems interact. Six monolingual Puerto Rican Spanish-speaking children and six bilingual Puerto Rican Spanish-English speaking children, ages 5–7 years, were included in the current study. Children’s single word productions were analyzed for (1) dialect density and (2) frequency of occurrence of dialect features (after Oetting & McDonald, 2002). Nonparametric statistical analyses were used to examine differences within and across language groups. Results indicated that monolinguals and bilinguals exhibited similar dialect density, but differed on the types of dialect features used. Findings are discussed within the theoretical framework of the Dual Systems Model (Paradis, 2001) of language acquisition in bilingual children.

This article examines the Swedish L2 development of deaf children by testing the validity of Processability Theory on deaf learners of Swedish as an L2. The study is cross-sectional and includes written data from 38 pupils (grades 5 and 10) from a school for deaf and hearing-impaired pupils in Sweden. The primary language used by the pupils is Swedish Sign Language with Swedish being considered their L2. The Swedish data have been analyzed through the lens of Processability Theory (PT). The results show that the grammatical development of deaf learners is similar to hearing learners of Swedish as an L2. The results therefore suggest that PT is applicable even for deaf learners of L2 Swedish.

This study investigates heritage speakers’ knowledge of plural formation in their colloquial varieties of Arabic, which use both concatenative and non-concatentative modes of derivation. In the concatenative derivation, a plural suffix attaches to the singular stem (muhandis ‘engineer-sg.’ → muhandis-iin ‘engineer-pl’); in the non-concatenative, the relation between the singular (gamal ‘camel’) and the plural (gimaal ‘camels’) typically involves vocalic and prosodic alternations with the main shared similarity between the two forms being the consonantal root (e.g., g-m-l). In linguistic approaches, non-concatenative patterns have been captured in different ways, though the earliest and most recognizable approach involves the mapping of a consonantal root onto a plural template. We investigated heritage speakers’ knowledge of the root and pattern system in two independent experiments. In Experiment 1, oral narratives were elicited from 20 heritage speakers and 20 native speakers of Egyptian and Palestinian Arabic. In Experiment 2, another group of 24 heritage speakers and 24 native speakers of the same dialects completed an oral picture-description task. The results of the two experiments show that heritage speakers’ knowledge of the root and pattern system of Arabic is not target-like. Yet, they have a good grasp of the root and template as basic units of word formation in their heritage Arabic dialects. We discuss implications for debates about the acquisition of the root and pattern system of Arabic morphology.

IRIS is a digital database of materials used to collect data for second language research that went fully live in August 2012. At the time of writing (May 2013), there have been over 3,300 downloads of materials held on the site, and almost 11,000 visits, demonstrating a clear need for the resource. IRIS has the potential to make a step-change in the way our field works, impacting the nature and rate of second language (L2) research. Here we outline the motivations for the project, what the IRIS database consists of, how it is structured, and the future of the resource.
