While much work has emphasized the role of the environment in language learning, research equally reports consistent effects of the child's knowledge, in particular, the words known to individual children, in steering further lexical development. Much of this work is based on cross-sectional data, assuming that the words typically known to…

Children who are deaf and hard of hearing (DHH) and learning to listen and speak begin developing spoken language skills later than their peers with typical hearing (TH). Consequently, it is well-documented that those children who are DHH lag their TH peers in spoken vocabulary development during their earliest years and on average, those lags…

Purpose: The purpose of this study is to develop an accurate test scale for vocabulary comprehension ability applicable to Mandarin-speaking preschool children aged 3-5. Methods: First, an initial scale was developed and evaluated using the expert consultation method. Subsequently, 490 typically developing 3-5-year-old Mandarin-speaking children…

We introduce a novel method to test a classic idea in developmental science that children's attention to a stimulus is driven by how much they can learn from it. Preschoolers (4-6 years, M=4.6) watched a video where a distracting animation accompanied static, page-by-page illustrations of a storybook. The audio narration for each storybook page…

Before they even talk, infants become sensitive to the speech sounds of their native language and recognize the auditory form of an increasing number of words. Traditionally, these early perceptual changes are attributed to an emerging knowledge of linguistic categories such as phonemes or words. However, there is growing skepticism surrounding…

Toddlers better retain novel object-label mappings from taxonomic categories they have more knowledge of. Separately, words for concepts with more perceptual features are learned earlier than words for concepts with fewer perceptual features. Because these factors have only been examined separately, it is unclear whether the effects of taxonomic…

Genetic factors are known to play a role in shaping reading abilities and their underlying cognitive processes. However, understanding how genetic and environmental factors interact to influence reading outcomes remains largely unknown. By evaluating the interplay between genetic and environmental influences on reading performance, this study aims…

Extensive reading (ER) has been found to have an assortment of positive effects on various aspects of second/foreign language learning. However, few studies have investigated its impacts on learners of Chinese as a Foreign Language (CFL), especially early beginning learners. To address this gap, this study reports an intervention of extensive…

Research on "parentese," the acoustically exaggerated, slower, and higher-pitched speech directed toward infants, has mostly focused on maternal contributions, although it has long been known that fathers also produce parentese. Given recent societal changes in family dynamics, it is necessary to revise these mother-centered models of…

This literature review examines the effectiveness of explicit morphological instruction in improving vocabulary knowledge and reading comprehension for middle and high school students. Socioeconomic disparities in early language exposure contribute to a significant word gap, limiting students' ability to access complex academic texts.…

This narrative literature review explores language as a precursor for developing children's psychosocial skills in war-torn areas. By utilising Bronfenbrenner's ecological theory, this study aimed to understand the lifelong consequences of early childhood language deprivation in war-stricken zones, thus suggesting intervention strategies to…

Knowledge and its acquisition are central to the field of curriculum studies, but the ways in which empirical studies of pedagogical approaches relate to theories of knowledge acquisition are under researched. This paper reports the outcomes of a rapid evidence assessment about the impacts of "experiential learning" (EL), regarded by…

In a recent study, preschoolers adapted their syntactic expectations about a familiar phrase in French; this adaptation affected later word learning. In two experiments, we probed the generality of this finding by replicating the experiment and extending it to a different expression in English. We examined the ambiguous phrase "the…

The cognitive mechanisms and benefits of active learning in early child development are poorly understood. The current study investigated 20-23-month-old infants' curiosity-driven information selection in a novel word learning task, designed to identify any potential advantage for active learning over passive learning. In a gaze-contingent…

This research aims to investigate the impact of an early literacy programme called 'Dialog, Play and Tell--Early Literacy Skills Support Practices with Mother Involvement (DPT-ELP)' on the early literacy skills of socio-economically disadvantaged children. An interventional mixed research design was implemented with 13 children attending municipal…
