Traditions of statistical significance testing in second language (L2) quantitative research are strongly entrenched in how researchers design studies, select analyses, and interpret results. However, statistical significance tests using "p" values are commonly misinterpreted by researchers, reviewers, readers, and others, leading to…

Studies investigating the possible effects of age at immigration (a proxy for age at onset of second language learning) on second language acquisition among immigrants often explicitly take the effect of length of residence in the destination country (a measure of exposure to opportunities to learn the second language) into account. A third…

Responds to a previous article on research in second-language learning, challenging the need for discussion on the promises and problems, and asserting the need to report definitive results. (Author/JL)

Studies of second language acquisition often employ analytical concepts defined relative to the target language. This practice can be a serious obstacle to investigation of crucial questions about the nature of the learners' languages. This comparative fallacy's drawbacks are illustrated through a framework designed to study interlanguage…

Four positions concerning foreign and second language learning ability in adults are summarized with attention to the "critical period" hypothesis. An argument is made for a shift from macro-correlational studies to controlled micro language learning research free of extralinguistic variables. (PMJ)

Explores the validity of Labov's (1969) "Observer Paradox," and the five axioms describing the problems involved in linguistic research, for interlanguage research. Methodological remedies are suggested. (AM)

From perspective of a psycholinguist, discusses three leading questions that have arisen from foundational, descriptive second-language-acquisiton studies: Why are certain L2 constructions learnable and others not?; In considering input requirements, is it fair to say that adult learners can take advantage of metalinguistic information about the…

This paper examined the assessment of second-language proficiency in 157 research articles published in 5 language journals from 1988 through 1992, finding 4 major conventions for the assessment of language proficiency: (1) impressionistic judgment; (2) institutional status; (3) in-house measures; and (4) standardized test scores. (64 references)…

Discusses the shortcomings of the morpheme order approach in first and second language acquisition research, and proposes instead the notion of developmental sequence, drawing on examples from data on four German children learning English naturalistically. (Author/AM)

First language studies show boys superior to girls in listening vocabulary, though girls are otherwise superior in language ability. A second language study used two sets of Chinese college students (n=285 and 205). Ten tests for proficiency in English and two listening vocabulary tests (described in text) yielded similar results.
