Purpose: Previous studies have reported the success of distributional learning for adult speakers across segmental and suprasegmental categories immediately after training. On the other hand, second language (L2) perception models posit that the ease with which learners perceive a nonnative speech contrast depends on the perceptual mapping between…

The present study was the first to investigate the ability to selectively trust reliable informants in a sample of Brazilian preschool children from two different socioeconomic backgrounds. Ninety-three 3- and 4-year-old children, equally distributed across a low- and medium-SES group, participated. A standard selective trust task was used.…

This study examined the associations of preschool children's executive function (EF) and learning behaviour (CLB) with their concurrent academic skills and the role of CLB as a mediator for the EF-academic skills link. One hundred seventy-nine children were assessed on EF and math and literacy skills. Parents and teachers completed a questionnaire…

Purpose: Recent behavioral studies have demonstrated the effectiveness of implementing retrieval practice into learning tasks for children. Such approaches have revealed that repeated spaced retrieval (RSR) is particularly effective in promoting children's learning of word form and meaning information. This study further examines how retrieval…

This article reports on two studies designed to examine the landscape of online streamed videos, and the features that may support vocabulary learning for low-income preschoolers. In Study 1, we report on a content analysis of 100 top language- and literacy-focused educational media programs streamed from five streaming platforms. Randomly…

Data from 1,407 preschoolers were used to examine the implications of classroom age composition for the early learning and development of 4-year-olds in classrooms with 3- and 5-year-olds also in attendance. Results suggest that a greater number of younger classmates did not detract from 4-year-olds' language development, literacy performance, or…

Although an abundant literature documents preliterate children's word learning success from shared storybook reading, a full synthesis of the factors which moderate these word learning effects has been largely neglected. This meta-analysis included 38 studies with 2,455 children, reflecting 110 effect sizes, investigating how reading styles, story…

The present study examined the relations between teacher-child interactions, teachers' Spanish use, classroom linguistic composition, and the school readiness skills of low-income, Latinx, Spanish-speaking dual language learners (DLLs), controlling for home and teacher background characteristics, with a national probability sample of Head Start…

This mixed methods study extends findings from a prior study exploring use of increasingly-complex, expository text situated within a five-week interdisciplinary intervention in which first-grade children attending a Sheltered-English (SEI) immersion classroom advanced their conceptual knowledge and academic language approximating levels near or…

Shared-book reading is a well-established intervention to foster vocabulary development. Factors influencing its effectiveness are, however, less well studied, particularly with regard to story-delivery. We contrasted a read-aloud with a free storytelling approach and tested effects on vocabulary learning. In the first study, 83 preschoolers aged…

This study investigated: 1) the influence of alphabet instructional content (letter names, letter sounds, or both) on alphabet learning and engagement of English only and dual language learner (DLL) children, and 2) the relation between children's initial status and growth in three underlying cognitive learning processes (paired-associate,…

Metalinguistic awareness is the ability to identify, reflect upon, and manipulate linguistic units. It plays a critical role in reading development. The present study investigated Chinese- and English-speaking preschoolers' metalinguistic awareness development and the role of cognitive and linguistic abilities in its development. Forty-two…

Research Findings: National policy today is on the brink of defining preschool experiences as essential for children's academic success. Indeed, many children's classroom experience begins as they transition from infant/toddler care to a preschool classroom. This study examined developmentally relevant skill domains among 36-month-olds (effortful…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

The aim of the current study was to examine different aspects of procedural memory in young adults who varied with regard to their language abilities. We selected a sample of procedural memory tasks, each of which represented a unique type of procedural learning, and has been linked, at least partially, to the functionality of the corticostriatal…
