Shin and Mill (2021) propose four steps children go through when learning "variable form use." Although I applaud Shin and Miller's focus on morphosyntactic variation, their accrual of evidence is post hoc and selective. Fortunately, Shin and Miller recognize this and encourage tests of their ideas. In support of their work, I share data…

The extensive literature on subject expression in Spanish makes for rich comparisons between generative (formal) and usage-based (functional) approaches to language acquisition. This article explores how the problem of subject expression has been conceptualized within each research tradition, as well as unanswered questions that both approaches…

Language is of vital importance to human beings. It is a means of communication and it has specific cognitive links. Advanced social cognition is necessary for children to acquire language, and sophisticated mind-reading abilities to assume word meanings and communicate pragmatically. Language can be defined as a bi-directional system that permits…

In this article I make the point that there has been a continuous focus on second language development in second language acquisition research for over 40 years and that there is clear empirical evidence for generalizable developmental patterns. I will both summarize some of the core assumptions of Processability Theory (PT) as an approach to…

This chapter introduces three applications of Bayesian inference to common and novel issues in second language research. After a review of the critiques of conventional hypothesis testing, our focus centers on ways Bayesian inference can be used for dealing with missing data, for testing theory-driven substantive hypotheses without a default null…

Second language (L2) researchers are becoming more interested in both L2 learners' knowledge of the target language and how that knowledge is put to use during real-time language processing. Researchers are therefore beginning to see the importance of combining traditional L2 research methods with those that capture the moment-by-moment…

Purpose: In 1963, Charles Van Riper published "My Grandfather," a short reading passage that has evolved into a ubiquitous metric of reading ability and speech intelligibility. In this historical note, we describe several heretofore unacknowledged similarities between "The Grandfather Passage" (Darley, Aronson, & Brown, 1975) and a portion of "The…

This paper outlines a procedure for language textbook analysis from the perspective of second language acquisition (SLA) principles as a preliminary procedure to evaluation for selection. The aim is to provide a tool that allows comparison of the potential of textbooks for supporting students' language learning. To this end, ten general principles…

Recent years have brought increasing attention to studies of language acquisition in a country where the language is spoken, as opposed to formal language study in classrooms. Research on language learners in immersion contexts is important, as the question of whether study abroad is valuable is still somewhat controversial among researchers…

In this article, I describe studies conducted over 25 years with secondary and post-secondary L2 learners in the United States. The evidence from these studies shows that there are important connections between students' early L1 skills and their L2 aptitude and L2 proficiency and that individual differences in students' L1 skills in elementary…

The structure of /s/-clusters has been a rather controversial subject due to their structural oddities. Studies on the acquisition of these clusters have contributed to the discussion to validate certain theoretical claims, and sonority-related issues have always been in focus. Cross-linguistic acquisition data from children with phonological…

Formative and design experiments represent a methodology uniquely suited for educational research. Providing a practical overview of this emerging approach, the authors address the following questions: What is the origin of formative and design experiments and how do they compare to other approaches to investigating interventions in classrooms?…

Describes "need" as a semiauxiliary and marginal modal and as a full lexical verb in present-day British English from the syntactic, lexical, semantic, and pragmatic points of view. The descriptions given by grammars as well as examples in British-English texts are compared. (14 references) (Author/CFM)

Research on second language acquisition (SLA) and research on foreign language learning (FLL), often regarded as different and separate fields of inquiry, are compared in a brief review of literature. Perceptions about the scopes and characteristics of the research are examined. Concerns about the relationship between SLA research and theory and…

Methods of data collection are reviewed that were used in 39 studies of interlanguage pragmatics, defined narrowly as the investigation of non-native speakers' comprehension and production of speech acts, and the acquisition of second language-related speech act knowledge. Data collection instruments are distinguished according to the degree to…
