Noun-class prefixes are obligatory in most Bantu languages. However, the Sotho languages (Sesotho, Setswana, Sepedi) permit a subset of prefixes to be realized as null at the intersection of "unmarked" phonological, syntactic, and discourse conditions. This raises the question of how and when the licensing of null prefixes is learned. Using…

In this article, we examine current practices in the measurement of syntactic complexity to illustrate the need for more organic and sustainable practices in the measurement of complexity, accuracy, and fluency (CAF) in second language production. Through in-depth review of examples drawn from research on instructed second language acquisition, we…

In second language acquisition (SLA) research, two types of second language (L2) knowledge, explicit and implicit, have been discussed for almost three decades. Although many SLA researchers agree that L2 instruction should give priority to implicit knowledge, researchers have not agreed on what type of test (e.g., oral narrative test and timed…

Two grammatical classes are commonly distinguished in psycholinguistic research. The open-class includes content words such as nouns, whereas the closed-class includes function words such as determiners. A standing issue is to identify whether these words are retrieved through similar or distinct selection mechanisms. We report a comparative…

We investigated the processing of violations of the verb position in Dutch, in a group of healthy subjects, by measuring event-related potentials (ERPs) through electroencephalography (EEG). In Dutch, the base position of the verb is clause final, but in matrix clauses, the finite verb is in second position, a construction known as "Verb Second".…

Researchers have long been puzzled by children's variable omission of grammatical morphemes, often attributing this to a lack of semantic or syntactic competence. Recent studies suggest that some of this variability may be due to phonological constraints. This paper explored this issue further by conducting a longitudinal study of five…

Learners of third language (L3) German and L3 French studied unfamiliar verbs that were cognate with first language (L1) Spanish equivalents, second language (L2) English equivalents, or neither. We examined whether learners would assume that the verbs shared syntactic frames with cognate forms in the typologically closer language. In immediate…

Using a self-paced reading task, the present study investigates how highly proficient second language (L2) speakers of German with English as their native language process unambiguous "wh"-subject-extractions and "wh"-object-extractions in German. Previous monolingual research has shown that English and German exhibit different processing…

The study looked at the effects of correction of learners' errors on learning of grammatical features. In particular, the manner of correction (explicit vs. implicit correction) was investigated. The study also focussed on the effectiveness of explicit and implicit correction of developmental early vs. developmental late features. Fifty-six…

Thai has imperfective aspectual morphemes that are not obligatory in usage, whereas English has obligatory grammaticized imperfective aspectual marking on the verb. Furthermore, Thai has verb final deictic-path verbs that form a closed class set. The current study investigated if obligatoriness of these grammatical categories in Thai and English…

The present study determined whether parenting style, defined by control strategies varying in power-assertion mediated the established relation between maternal language usage (grammar and semantics) and child language (grammar, semantics and pragmatics) during toddlerhood (n = 60). Based upon their use of control strategies mothers were…

The present study reports the findings of an experiment on the effects of explicit information on the learning of German case markings. Fifty-nine learners of first- and second-year German received computer-based processing instruction on German accusative case marking and word order. These learners were divided into two groups: one received…

Passives has been the focus of much research in language acquisition since the 1970s. It has been clear from this research that young children seldom produce passives spontaneously, particularly "long" or "full" passives with a by-phrase; and they usually perform poorly on experimental tests of the comprehension of passives, especially passives of…

While agreeing with Lardiere that the "parameter-resetting" approach to understanding second language acquisition (SLA) needs rethinking, it is suggested that a more construction-based perspective runs the risk of losing deductive and explanatory power. An alternative is to investigate the constraints on feature assembly/re-assembly in second…

In many adult literacy programs around the country, instruction emphasizes reading, but equal time is not given to the development of writing skills. Adult students are often reluctant to expose the difficulties they have with writing, difficulties which will be painfully apparent when they do write. With students who are reluctant to write,…
