Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection.…

This study compares monolinguals and different kinds of bilinguals with respect to their knowledge of the type of lexical phenomenon known as collocation. Collocations are word combinations that speakers use recurrently, forming the basis of conventionalized lexical patterns that are shared by a linguistic community. Examples of collocations…

This study adjudicates between two opposing accounts of morphological productivity, using English past-tense as its test case. The single-route model (e.g., Bybee & Moder, 1983) posits that both regular and irregular past-tense forms are generated by analogy across stored exemplars in associative memory. In contrast, the dual-route model…

CHALLENGE is generally perceived as a negative word synonymous with "dispute," "defy," "confrontation," and "contest." However, when resorting to dictionary definitions, CHALLENGE has unexpectedly been found to possess positive senses such as "stimulating" and "arousing competitive…

It has been observed that there is a strong association between the inherent (lexical) aspect of verbs and the acquisition of tense-aspect morphology (the aspect hypothesis; Andersen & Shirai, 1994). To investigate why such an association is observed, this study examined the influence of inherent aspect and learners' first language (L1) on the…

This descriptive study analyzed the emergence of the imperfect in the written production of 30 beginning learners of Spanish. The analysis focused on the use of the imperfect and the morphological marking of state verbs. The results follow the patterns predicted by the aspect hypothesis (Andersen and Shirai, 1994), and support some refinements of…

Pinker and Prince (1988) argued that two dissociable systems underlie the development of linguistic representations: one rule governed and the other associative. These two dissociable systems of representation and processing are claimed to be a linguistic universal (Pinker, 1999). Therefore, one should expect that nonnative speakers of a language…

The meaning of a word often cannot be formulated by conscious rules, because it is unconscious. Evidence on the verb "break" demonstrates this. The consequence for teaching is that teachers cannot supply meanings in words, but should present a wide range of uses of a word, so that students can intuit the unconscious generalization. (Author)

Examines the emergence of the present perfect in the interlanguage of instructed adult learners of English as a Second Language. Findings indicate that adding a new inflection in the tense/aspect system requires establishing new form-meaning associations as well as revising existing ones. (44 references) (Author/CK)
