Three experiments investigated the acquisition of English epistemic modal verbs (e.g., "may", "have to"). Semantically, these verbs encode possibility or necessity with respect to available evidence. Pragmatically, the use of weak epistemic modals often gives rise to scalar conversational inferences (e.g., "The toy may be…

This study examined the comprehension of actional and psychological verbs in both their active and passive (short and long) forms by 99 Serbian-speaking children. The children, whose age ranged between 3 years, 6 months (3;6) and 7 years, 6 months (7;6), were divided into three groups: 3;6-5 ("M" = 4.3), 5;1-6;1 ("M" = 5.6),…

This article examines the acquisition of embedded verb placement in Swedish children, focusing on Neg-V and V-Neg order. It is proposed that a principle of economy of movement creates an overuse of V-Neg order in embedded clauses and that the low frequency of the target-consistent Neg-V order in child-directed speech obstructs children from…

Young English-speaking children often omit auxiliary verbs from their speech, producing utterances such as "baby crying" alongside the more adult-like "baby is crying." Studies have found that children's proficiency with auxiliary BE is correlated with frequency statistics in the input, leading some researchers to argue that…

The lexical mapping of abstract functional words like modal verbs is an open problem in acquisition (e.g., Gleitman et al. 2005). In diachronic linguistics it has been proposed that learner mapping errors are responsible for innovations in the historical record (see Kiparsky 1974; Roberts & Roussou 2003, among others). This suggests that child…

This article presents the results of experimental data on language production and comprehension. These show that adult learners of Dutch as an additional language, with different language backgrounds, and a L2 proficiency below level A2 (Waystage) of the Common European Framework of Reference for Languages (CEFR; Council of Europe, 2001), use…

Two recent proposals link the use of nonagreeing "don't" to the Root Infinitive (RI) Stage. Guasti & Rizzi (2002) argue for a misset parameter involving how agreement is spelled out. Schütze (2010) proposes that Infl is underspecified in child language and that "do" surfaces to support the contracted clitic/affix…

In the study conducted using qualitative research methods, one of the purposeful samplings, typical case sampling was used. The date were collected from two sources. The students were asked to prepare any topic they wanted and then delivered it. The students were observed for one month in order to detect their mistakes as they speak, through…

Syntactic structure has been considered an integral component of agreement computation in language production. In agreement error studies, clause-boundedness (Bock & Cutting, 1992) and hierarchical feature-passing (Franck, Vigliocco, & Nicol, 2002) predict that local nouns within clausal modifiers should produce fewer errors than do those within…

In this article, we report the results of a self-paced reading experiment designed to investigate the question of whether or not advanced French and German learners of English as a second language (L2) are sensitive to tense/aspect mismatches between a fronted temporal adverbial and the inflected verb that follows (e.g. *"Last week, James has…

This paper examines two issues concerning nonagreeing "don't" in child English, e.g., "He don't fit". (1) Do children know that "don't" consists of auxiliary "do" plus sentential negation, or do they misanalyze it simply as negation? I argue that the former claim yields both empirical (distributional) and conceptual advantages, while the latter…

The criteria employed in most textbooks to differentiate "ser" and "estar" followed by an adjective are mainly semantic. Most exercises offer to second language learners too high a proportion of "estar" usages, a practice that leads to overgeneralization with regard to the use of "estar." An experiment was…

This is a quarterly report of a project involving the analysis of the language of four Puerto Rican children living in the Boston area who are learning Spanish as a first language. The children, all male, ranged in age from 17 months to 37 months during the period of study. All had some contact with English. The data were transcriptions of…

Addressed whether hierarchical relations and word order can be separated in sentence production. Assessed in two experiments whether subject-verb agreement errors require linear proximity of a so-called "local" noun to the verb. Found evidence for a stage in language production in which a syntactic structure is built prior to stage in which words…

Spontaneous speech samples of 15 children were analyzed for appropriate and inappropriate use and nonuse of the past tense verbal inflection. It was found that: (1) two types of overgeneralization errors have acquisitional relevance; and (2) partial regularity blocks overgeneralization errors. Two hypotheses were not supported. (CHK)
