We conducted a multisite replication study with aspects of preregistration in order to explore the feasibility of such an approach in second language (L2) research. To this end, we addressed open questions in a line of research that has examined whether having learners attend to form while reading or listening to a L2 passage interferes with…

The current study responds to the call for increased dialogue among different areas of additional language research. Specifically, we bring together learner corpus research and variationist approaches to second language acquisition to advance learner corpus research in two ways: (a) by modeling interlanguage development and variability and (b) by…

This article proposes basic (shared) and extended (nonshared) language cognition in native speakers as a function of two types of extralinguistic attributes: (a) degree of being multilingual and (b) variables related to amount and type of literacy experiences (e.g., level of education). This approach may throw new light on the question of whether…

A hallmark of grammatical knowledge is the ability to parse novel syntactic structures. Previous artificial language studies have examined learning hierarchical structures, but few have involved meaningful language and shown generalization to novel structures. This study addressed this issue using the semiartificial language paradigm. The…

There remains considerable disagreement about which factors drive second language (L2) ultimate attainment. Age of onset (AO) appears to be a robust factor, lending support to theories of maturational constraints on L2 acquisition. The present study is an investigation of factors that influence grammatical and lexical complexity at the stage of L2…

This article introduces two sophisticated statistical modeling techniques that allow researchers to analyze systematicity, individual variation, and nonlinearity in second language (L2) development. Generalized linear mixed-effects models can be used to quantify individual variation and examine systematic effects simultaneously, and generalized…

We examined case-marking variation in heritage Polish, Russian, and Ukrainian. Comparing heritage to homeland Polish and Ukrainian speakers, we found only a few types and a few tokens of systematic distinction between heritage and homeland varieties. A total of 6,291 instances of nouns and pronouns were extracted from transcribed conversations…

When native speakers judge the acceptability of novel sentences, they appear to implicitly take competing formulations into account, judging novel sentences with a readily available alternative formulation to be less acceptable than novel sentences with no competing alternative. Moreover, novel sentences with a competing alternative are more…

This study aimed to advance research on first and second language future-time expression in Spanish and to demonstrate the strengths of combining functionalist, concept-oriented approaches (e.g., Andersen, 1984; Bardovi-Harlig, 2000; Shirai, 1995; von Stutterheim & Klein, 1987) with variationist approaches. The study targeted 140 participants…

Idealization plays a fundamental role in scientific inquiry. This article examines the case for maintaining the claim that the second language acquisition (SLA) of grammatical structures such as negation manifests identifiable stages of acquisition. It proposes that, while research has demonstrated the need for de-idealization, there is no need to…

This study investigated how standard and substandard varieties of first language (L1) Dutch affect grammatical gender assignments to nouns in second language (L2) German. While German distinguishes between masculine, feminine, and neuter gender, the masculine--feminine distinction has nearly disappeared in Standard Dutch. Many substandard Belgian…

In the past 15 years, a substantial body of evidence has confirmed that a powerful distributional learning mechanism is present in infants, children, adults and (at least to some degree) in nonhuman animals as well. The present article briefly reviews this literature and then examines some of the fundamental questions that must be addressed for…

This study builds on research investigating the construct validity of elicited imitation (EI) as a measure of implicit second language (L2) grammatical knowledge. It differs from previous studies in that the EI task focuses on a single grammatical feature and time on task is strictly controlled. Seventy-three EFL learners and 20 native English…

Previous studies show that second language (L2) learners with large phonological memory spans outperform learners with smaller memory spans on tests of L2 grammar. The current study investigated the relationship between phonological memory and L2 grammar in more detail than has been done earlier. Specifically, we asked how phonological memory…

Each of us as language learners had different language experiences, yet somehow we have converged upon broadly the same language system. From diverse, often noisy samples, we have attained similar linguistic competence. How so? What mechanisms channel language acquisition? Could our linguistic commonalities possibly have converged from our shared…
