According to the Interface Hypothesis (IH) (e.g., Tsimpli & Sorace 2006; Sorace 2011), external interfaces are more challenging for L2 learners than internal interfaces. It is not clear, however, if linguistic phenomena associated with external interfaces are necessarily problematic and if internal interfaces are necessarily unproblematic. In…

By means of a large-scale web-based investigation, we established the degree of mutual intelligibility of 16 closely related spoken languages within the Germanic, Slavic and Romance language families in Europe. We first present the results of a selection of 1833 listeners representing the mutual intelligibility between young, educated Europeans…

This study investigates the use of the Spanish subjunctive in bilingual children with and without specific language impairments (SLI). Using an elicitation task, we examine: (i) the potential of the subjunctive as a grammatical marker of SLI in Spanish-English bilingual children, (ii) the extent to which degree of bilingualism affects performance,…

Textual manipulation is a common pedagogic tool used to emphasize specific features of a second language (L2) text, thereby facilitating noticing and, ideally, second language development. Visual input enhancement has been used to investigate the effects of highlighting specific grammatical structures in a text. The current study uses a…

This study examined multimedia instruction (MI) effects on the development of the French prototypical and non-prototypical past forms among Hispanophone learners. During 4 weeks of classroom instruction, participants were exposed to MI in one of 4 conditions: learners at early stages of past-tense development received MI including prototypical (n…

This study focuses on variation within a group of learners of Spanish (N = 253) who produced requests and complaints via a written discourse completion task. It examines the effects of learner and situational variables on production--the effect of proficiency and addressee-gender on speech-act choice and the effect of perception of imposition on…

This study investigated the relationship between syntactic comprehension at the sentence level and text-level comprehension. The study isolated the specific contribution of syntax by asking whether sentence comprehension efficiency of difficult syntactic constructions explained variance in text comprehension after controlling for sentence…

Based on the schema theory, it has been found that the background knowledge of males and females differs. This difference in background knowledge can affect the students' reading comprehension. In Iran, although boys and girls study in different schools, they follow the same curricula and syllabuses in all the schools. The present article reports…

The optional use of morphology attested in second language learners has been attributed either to a representational deficit or to a "surface" problem with respect to the realization of inflectional affixes. In this article we contribute to this issue by providing empirical data from the early interlanguage of Greek learners of Turkish. Three…
