The Douglas Fir Group (2016) sought to articulate a transdisciplinary agenda for SLA but said little about multilingualism specifically. Moreover, many multilinguals are under siege in a worrisome world where threats to human difference have risen to the mainstream in the aftermath of Brexit and the 2016 U.S. presidential election. I argue that…

Linguistic geniuses such as Heinrich Schliemann have long fascinated many with their exceptional capabilities to master multiple languages on top of their own mother tongues. These individuals are believed to be able to extract the probabilistic, abstract patterns underlying a target form's linguistic and frequency distribution in second language…

Early conceptions of aptitude were concerned with explicit learning abilities in formal learning settings, which according to MLAT (Modern Language Aptitude Test) were measurable based on a phonemic coding ability, an inductive learning ability, an associative memory, and a grammatical sensitivity (Carroll, 1962). However, recent understanding on…

The traditional definition of language aptitude sees it as "an individual's initial state of readiness and capacity for learning a foreign language, and probable facility in doing so given the presence of motivation and opportunity" (Carroll, 1981, p. 86). This conception portrays language aptitude as a trait, in the sense of exhibiting…

This study investigated fast mapping in late-talking (LT) toddlers and toddlers with normal language (NL) development matched on age, nonverbal cognition, and maternal education. The fast-mapping task included novel object labels and familiar words. The LT group scored significantly lower than the NL group on novel word comprehension and…

In addition to providing an account of the empirical facts of language, a theory that aspires to account for language as a biologically based human faculty should seek a graceful integration of linguistic phenomena with what is known about other human cognitive capacities and about the character of brain computation. The present discussion note…

The presence or absence of clinically delayed language development prior to 3 years of age is a key, but contentious, clinical feature distinguishing autism from Asperger's disorder. The aim of this study was to examine language processing in children with high-functioning autism (HFA) and Asperger's disorder (AD) using a task which taps lexical…

Fifty-four students were followed over 10 years beginning in first grade to determine best predictors of oral and written second language (L2) proficiency. Predictor variables included measures of first language (L1) skill administered in first through fifth grades, L1 academic aptitude, L2 aptitude (Modern Language Aptitude Test), and L2 affect…

A collection of papers, all by the author, looks at a variety of theories and theoretical approaches from linguistics, sociolinguistics, and psycholinguistics and their applications to the teaching of English as a second language. Two studies are also presented. Titles include: "Content Schemata and Second Language Learning";…

Drawing on recent psychological and neurological research on how individual differences might interact with learning a particular language, the study examines how psycholinguistic research and theory can help in assigning military personnel to language training and to a given language. Using the Defense Language Institute's Defense Language…
