Purpose: Our purpose was to test the competing sources of input (CSI) hypothesis by evaluating an intervention based on its principles. This hypothesis proposes that children's use of main verbs without tense is the result of their treating certain sentence types in the input (e.g., "Was 'she laughing'?") as models for declaratives…

Previous research on reference tracking has revealed a tendency towards over-explicitness in second language (L2) learners. Only limited evidence exists that this trend extends to situations where the learner's first and second languages do not share a sensory-motor modality. Using a story-telling paradigm, this study examined how hearing novice…

Research on multilingual acquisition has investigated various combinations of languages to identify the factors determining how learners express motion. Our research examines the semantics of motion expression in learners whose first language (L1) exhibits more variation than their foreign language (L2/L3). The present study compares upward motion…

This article explores the second language acquisition of motion events, with particular regard to cross-linguistic influence between first and second languages. Oral narratives in Spanish as a second language by native speakers of French, German and Italian are compared, together with narratives by native Spanish speakers. Previous analysis on the…

The authors compared performance on two variants of the primed lexical decision task to investigate morphological processing in native and non-native speakers of English. They examined patterns of facilitation on present tense targets. Primes were regular (billed-BILL) past tense formations and two types of irregular past tense forms that varied…

The aim of the article is to provide preliminary data on the use of auxiliaries and clitics in Serbian-speaking children with developmental language impairment. Two groups of children (a group of 30 children with developmental language impairment and a group of 30 typically developing children) aged between 48 and 83 months and matched on IQ took…

In this article we examine language processing and development in Catalan or Spanish-speaking children with SLI, focusing on the study of the verb. We analyse the key initial phase of its process of acquisition and aim to define common features of the SLI group that distinguish them from children with normal language development. We intend to…
