Young learners are known to extend verb regularity further than it actually is. When it happens, this children's overregularization phenomenon can be a result of several reasons: a failed linguistic development due to confusion between rules and memory, a lack of feedback from adults, and problems with cognitive development. The present study…

Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

This paper explores whether there is evidence for age and/or input effects in child L2 acquisition across three different linguistic domains, namely morphosyntax, vocabulary, and syntax-semantics. More specifically, it compares data from English-speaking children whose age of onset to L2 Dutch was between one and three years with data from…

Using an observational task followed by an experimental task with an Intermodal Preferential Looking Paradigm, we examined the effect of input on children's acquisition of class extension rules by investigating the relationship between the amount of polysemous noun-verb pairs in French-speaking 2-year-olds' input and both their spontaneous…

It has been argued that children learning a second language (L2) omit agreement inflection because of communication demands. The conclusion of these studies is that L2 children know the morphological and syntactic properties of agreement inflection, but sometimes insert an inflectional default form (i.e., the bare verb) in production. The present…

In the present study, the natural and simultaneous first language acquisition of a German-Italian bilingual boy and an Italian monolingual girl from 1;8 to 2;1 are analyzed and compared. The investigation focuses on the rate of acquisition and the size and composition of the productive lexicons. At the end of the observation period, the bilingual…

The aim of this article is two-fold: to test the Aspect Hypothesis, according to which the early use of tense-aspect morphology patterns by semantic/aspectual features of verbs, and Tense is initially defective (e.g. Antinucci and Miller, 1976; Bloom et al., 1980; Andersen and Shirai, 1994; 1996; Robison, 1995; Shirai and Andersen, 1995;…

This paper examines the nature of finite and nonfinite main declarative sentences produced by L2 child learners. It claims that two of the main proposals on the root infinitive (RI) phenomenon, the Truncation Hypothesis (TH) and the Missing Surface Inflection Hypothesis (MSIH), are not mutually exclusive in child SLA because they are hypotheses on…

Investigates whether the aspect-before-tense hypothesis accounts for the acquisition of tense-aspect morphology in child second language English. Addressed whether early uses of tense-aspect inflections can be analyzed as a spell-out of semantic/aspectual features of verbs. Data are from a longitudinal study of an 8-year-old Russian-speaking child…

We present morphological analyses of verb inflections produced by 15 Spanish-speaking children (age range: 1;7 to 4;7) taken from longitudinal and cross-sectional samples of spontaneous speech and narratives. Our main observation is the existence of a dissociation between regular and irregular processes in the distribution of errors: regular…

Basque auxiliary verbs encode tense, agreement relations with ergative, absolutive, and dative arguments, which constitute an inflectional verbal amalgam whose acquisition is not problematic for Spanish-speaking children but is for Spanish-speaking adults. This asymmetry is due to different processes by which the inflectional amalgam is acquired.…

Studies of the acquisition of word meaning and the semantic features involved have been mostly confined to noun categories and polar adjectives. Investigation of the semantic categories underlying verb forms has implications not only for theories of child language acquisition but also for theories of semantic structure in general. Experimental…

Reviews data on the acquisition of German without formal instruction by native speakers of Korean, Turkish, Italian, and German, on the acquisition of French by English speakers, and of the acquisition of English by speakers of various first languages (L1). Evidence indicates that the sole projections that the learner transfers from the L1 are…

Looks at naturalistic samples of adult-to-child speech to determine whether variations in the input are consistent with reported variations in the proportions of nouns and verbs in children's early vocabularies. Naturalistic speech samples from English-, Italian-, and Mandarin-speaking children and their caregivers were examined. (Author/JL)

Several recent reports on the untutored second language acquisition of English have suggested that the same developmental sequence holds for the acquisition of the interrogative structures irrespective of whether English is acquired as a first language (L1) or a second language (L2). These studies have been conducted within the Klima & Bellugi…
