Learners of a nonnull subject language (e.g., English) whose first language (L1) is a null subject language (e.g., Spanish) can show some optionality in the interpretation of overt subject pronouns in the second language (L2). By exposing L2 learners to nativelike interpretations of pronouns in discourse, we aim at understanding how exposure can…

The term "formulaic sequence" (FS) is used with a multiplicity of meanings in the SLA literature, some overlapping but others not, and researchers are not always clear in defining precisely what they are investigating, or in limiting the implicational domain of their findings to the type of formulaicity they focus on. The first part of…

Two eye-tracking experiments tested (a) whether L2 learners benefit from the consistency of input modality (auditory instead of written processing instruction [PI] training) and (b) whether they benefit from training using the same voice as the test voice. Results confirmed a robust effect of PI training on picture-selection accuracy, yet the…

Based on writing produced by second language learners at different proficiency levels (CEFR A1 to C1), we adopted a usage-based approach (Ellis, Römer, & O'Donnell, 2016; Tyler & Ortega, 2018) to investigate how German and Spanish learner knowledge of 19 English verb-argument constructions (VACs; e.g., "V with n," illustrated by…

The purpose of this study was to determine whether processability theory (PT; Pienemann, 1998, 2005) accounts for the emergence of grammatical forms and structures in comprehension. Sixty-one learners of English participated in oral interviews that elicited a variety of structures relevant to PT. Learners were divided into two groups: those who…

This study examines heritage speakers' knowledge of Standard Arabic (SA) and compares their patterns of SA acquisition to those of learners of SA as second/foreign language (L2). In addition, the study examines the influence of previously acquired language varieties, including Colloquial Arabic (QA), on SA acquisition. To this end, the study…

The role of explicit information (EI) as an independent variable in instructed SLA is largely underresearched. Using the framework of processing instruction, however, a series of offline studies has found no effect for EI (e.g., Benati, 2004; Sanz & Morgan-Short, 2004; VanPatten & Oikkenon, 1996). Fernandez (2008) presented two online experiments…

Investigates the relative effect of two types of explicit grammar instruction on learners' ability to interpret and produce sentences containing the French causative. Indicates processing instruction is as effective as traditional instruction in enabling learners to interpret the French causative; traditional instruction is more effective in…

Investigates how second language intake was affected both by awareness and by the conditions under which a problem-solving task was performed. Spanish conditional sentences were presented to learners through five different degrees of explicitness. Intake was measured through a multiple-choice recognition test administered immediately after the…

Examines the extent to which Japanese learners of English as a Second Language acquired a rule regulating the argument structure frames of novel English verbs after exposure to grammatical examples of sentences containing the verbs. Results showed significant differences in the extent of learning, with the focus-on-form conditions outperforming…

Focuses on the application of the Null Subject Parameter. Data reveals that some second-language learners exhibit knowledge that English is morphologically nonuniform yet still accept English null subject sentences. Findings disprove the Morphological Uniformity Hypothesis, indicating that any reformulation of the Null Subject Parameter must…
