Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

Purpose: Conversational latency entails the temporal feature of turn-taking, which is understudied in autistic children. The current study investigated the influences of child-based and parental factors on conversational latency in autistic children with heterogeneous spoken language abilities. Method: Participants were 46 autistic children aged…

The present study investigates the impact of meaningful input on L2 learners' vocabulary use and their fluency in oral performance (immediate and repeat tasks), as well as whether the effects are mediated by learners' prior vocabulary knowledge and working memory. Ninety university students learning English as a foreign language were randomly…

This study examines the role of receptive vocabulary knowledge on outcomes of the TOEFL reading comprehension task. Participants included 18 native speakers of Spanish learning English as a foreign language and 17 native speakers of English ranging in age from 19-25 years. Lexical stimuli were presented auditorily and were divided into…

Purpose: Previous research shows that shared storybook reading interactions can function as effective speech and language interventions for young children, helping to improve a variety of skills--including word-learning. This study sought to investigate the potential benefits of elaboration of new words during a single storybook reading with…

This research aims to improve the vocabulary knowledge of Thai EFL students by using audio-visual aids as instructional tools. Hopefully, this study serves as an initial foundation to develop students' vocabulary knowledge and benefit the pedagogical development in Thailand. Consequently, this research aimed to explore the effectiveness of…

This article aims to uncover how alignment affects second language (L2) vocabulary acquisition by Chinese-speaking learners of English as they interact with various interaction loads (i.e. input text, peers and video). It also explores how tasks with varying interactional intensity in relation to the interaction loads influence the alignment…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

Erlam & Ellis (2018) published, in "Canadian Modern Language Review", an experimental study that investigated the effect of input-based tasks on the acquisition of vocabulary and markers of plurality by adolescent near-beginner learners of L2 (second language) French. The present paper reports an approximate replication of the…

Specific features of adult linguistic input may play a larger, or smaller role, at different child ages, across different language outcomes, in different cohorts. This prospective, longitudinal study explored associations between the quantity and quality (i.e. diversity and responsiveness) of maternal linguistic input and child language. This…

It is widely believed that reading to preschool children promotes their language and literacy skills. Yet, whether early parent-child book reading is an index of generally rich linguistic input or a unique predictor of later outcomes remains unclear. To address this question, we asked whether naturally occurring parent-child book reading…

Purpose: The current study was designed to investigate the differences in language input related to family factors (maternal level of education [MLE] and socioeconomic level of deprivation [SLD]) and their association with language outcomes in preschoolers. Method: This study used New Zealand SLD and MLE classification systems to examine…

To investigate the skill transfer and the effects of practice schedules in the learning of second language syntax, 129 intermediate-level English learners were divided into six groups, based on practice format (input vs. output practice) and practice schedule (blocked vs. interleaved vs. hybrid [blocked + interleaved]). Analyses revealed that the…

Knowing enough vocabulary is crucial for second language learners to comprehend and produce the language. Therefore, a substantial bulk of research has aimed at finding the most effective ways to acquire new words. The Task-induced Involvement Load Hypothesis (Laufer & Hulstijn, 2001) states that vocabulary tasks are efficient when they induce…

Content and Language Integrated Learning (CLIL) has become the focus of Foreign Language (FL) research within the last decades. CLIL provides a more complete, naturalistic, and meaningful context to FL learning, which has proven to bring many benefits to learners, such as a higher motivation and promotion of creativity, and better results in…
