Two experiments tested how the number of illustrations in storybooks influences 3.5-year-old children's word learning from shared reading. In Experiment 1, children encountered stories with two regular-sized A4 illustrations, one regular-sized A4 illustration, or one large-sized A3 illustration (in the control group) per spread. Children learned…

Purpose: Frequent sounds and frequent words are both acquired at an earlier age and are produced by children more accurately. Recent research suggests that frequency is not always a facilitative concept, however. Interactions between input frequency in perception and practice frequency in production may limit or inhibit growth. In this study, we…

Whereas adults often rely on explicit memory, children appear to excel in implicit memory, which plays an important role in the acquisition of various cognitive skills, such as those involved in language. The current study aimed to test the assertion of an age-dependent shift in implicit versus explicit learning within a theoretical framework that…

An ongoing question in second language vocabulary learning is how to optimize the acquisition of words. One approach is the so-called "spaced repetition technique" that uses intervals to repeat words in a given time frame (Balota et al., 2007; Leitner, 1972; Oxford, 1990; Pimsleur, 1967; Roediger & Karpicke, 2010; Schuetze &…

Purpose: Previous research has demonstrated equivocal findings related to the effect of listener age on intelligibility ratings of dysarthric speech. The aim of the present study was to investigate the mechanisms that support younger and older adults' perception of speech by talkers with dysarthria. Method: Younger and older adults identified…

This short contribution is a response to Stein's critical review of the New General Service List; it reviews Stein's argument and replies to the main points raised in her paper. We identify and discuss three fundamental principles of wordlist creation. In particular, we focus on defining and operationalising the vocabulary construct and the…

This paper describes an investigation into the function of child-directed speech (CDS) across development. In the first experiment, 10-21-month-olds were presented with familiar words in CDS and trained on novel words in CDS or adult-directed speech (ADS). All children preferred the matching display for familiar words. However, only older toddlers…

This study was conducted to determine the vocabulary coefficients of the themes in 7 Turkish textbooks taught during the 2019-2020 academic year. The study of the vocabulary coefficients of the themes is a method specific to the claim of the research. There are subject scopes and concept areas specific to the themes in the Turkish textbooks. The…

Parent input during interaction with young children varies across languages and contexts with regard to the relative number of words from different lexical categories, particularly nouns and verbs. Previous work has focused on spoken language input. Little is known about the lexical composition of parent input in American Sign Language (ASL). We…

The presence of mobile technologies within preschool and elementary classrooms has been increasing, yet review studies which measure the effectiveness of mobile technologies to support children's literacy achievement remains scarce. The purpose of this study is to conduct a systematic review to examine the influence of mobile technologies on…

Purpose: Derivational morphology and compounds are important aspects of academic vocabulary. However, investigation of the development of expressive derivational and compound morphology using language sampling is sparse. This cross-sectional study used three types of language samples to investigate quantitative and qualitative changes in the…

This study investigates the effects of an integrated oral language and listening comprehension intervention for early elementary students with ASD. Students (n = 43) were randomly assigned to intervention or control comparison conditions, with intervention students receiving instruction in small groups of 3 or 4. Groups were led by special…

The purpose of the present study was to explore the dimensionality of the English home language and literacy environment (HLLE) construct in multilingual home settings for fourth- and fifth-grade emergent bilinguals. The authors also evaluated a framework of mediating mechanisms underlying the effects of emergent bilinguals' English HLLE on…

Learning vocabulary in any foreign language including English is vital, since it plays a central role in language learning. However, when compared to other skills, it is undoubtedly the most time-consuming skill to be mastered by learners and users of English due to various reasons. While learners exert much effort to memorise, store, and retrieve…

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child-directed speech to create quantitative features representing natural variability in word contexts. We…
