Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

Event-related potentials (ERPs) have become widespread in second language acquisition (SLA) research and a growing body of literature has been produced in recent years. We surveyed 61 SLA papers that use ERPs to study L2 sentence processing in healthy late learners. Our main aim was to provide a critical summary of findings from the decade…

The two possible positions for "wh"-words (i.e., in situ or preposed) represent a long-standing area of research in French. The present study reports on statistical analyses of a new seminaturalistic corpus of child L1 French. The distribution of the "wh"-words is examined in relation to a new verb tripartition: Free…

This project examines whether second-language (L2) learners can converge on a native-like pattern at the interface between syntax and discourse under low and high processing pressure, using Spanish clitic-doubled left dislocation (CLLD) as a test case. The original version of the Interface Hypothesis (IH) predicts that L2 competence on…

The Bottleneck Hypothesis argues that properties of inflectional morphology explain why second-language learners may face persistent difficulties in articulating meaning in target-language forms. In particular, the acquisition task proves even harder when first and second languages differ in the way they organize the mapping of functional features…

The present study is designed to investigate whether children's difficulties with subject-to-subject raising (StSR) are due to intervention effects. We examine English-speaking children's comprehension of StSR with "seem" and Spanish-speaking children's comprehension of StSR with "parecer" 'seem,' a configuration never before…

This study examined two common accounts of heritage speakers' nonnative attainment in their heritage/first language (L1), one attributing it to the influence of the second language (L2) and another to insufficient L1 input. Three groups of children who were heritage speakers of Arabic and who varied in their age of L2 exposure and type and amount…
