Fraction arithmetic facility is fundamental to learning more advanced math topics. However, attaining the ability to add and subtract fractions is hard for many students. The present longitudinal study examined students' growth on simple addition and subtraction word problems between fourth and sixth grades (N = 536). Latent class growth analyses…

Educators recognize children's social competence as an indicator of school readiness. Children's social competence may be promoted prior to kindergarten through parents' discipline. We assessed parent discipline as a predictor of 37 low-income pre-schoolers' social skills over four months. Parents answered open-ended questions about how they would…

Relatively few studies have directly examined children's memory of object-based spatial structure of room-sized environments. The current study investigated how children remember the spatial structure of a room, and the role of pictorial working memory (WM) and different testing perspectives in this process. In Experiment 1, 80 children aged 5 to…

Research Findings: The purpose of this study was to examine mothers' sophisticated vocabulary while reminiscing with their preschool-aged children, and its relation to children's story comprehension. The study used a cross-lagged panel design in which all assessments were collected twice, 6 months apart. We also compared two methods of examining…

Introduction: Social knowledge is an important aspect of social cognition that pertains to broader knowledge of social concepts and norms. People with intellectual disabilities are more likely to experience mental health challenges, and it's important to pay special attention to how comorbid conditions can affect their social cognition skills,…

Purpose: We evaluated whether naive listeners' ratings of the gender typicality of the speech of children assigned male at birth (AMAB) and children assigned female at birth (AFAB) were different at two time points: one at which children were 2.5-3.5 years old and one when they were 4.5-5.5 years old. We also examined whether measures of speech,…

Aim: The aim of the study was to examine longitudinal growth in intelligibility in connected speech from 2 to 8 years of age in children with cerebral palsy. Method: Sixty-five children with cerebral palsy participated in the longitudinal study. Children were classified into speech-language profile groups using age-4 data: no speech motor…

Few studies have examined growth and predictors of receptive vocabulary in children with autism spectrum disorder. Here we aimed to compare receptive vocabulary from 4 to 8 years and identify predictors of receptive vocabulary, at 8 years, in children with and without autism spectrum disorder. Participants were drawn from a nationally…

Inference making is fundamental to the construction of a coherent mental model of a text. We examined how vocabulary and verbal working memory relate to inference development concurrently and longitudinally in 4- to 9-year-olds. Four hundred and twenty prekindergartners completed oral assessments of inference making, vocabulary breadth, vocabulary…

Previous studies showed that bilinguals tend to score lower on some language tests than monolinguals in each of their languages and outperform monolinguals on some cognitive tasks. We investigated whether short-term and working memory capacities that underlie language abilities differ between sequential bilinguals and monolinguals. We tested…

This study examined variability of the home literacy environment (HLE) using multiple measures among families of low SES. The relations of the measures to each other and to children's early oral language skills and print knowledge were reported. Considerable variability of the self-reported HLE items and the Children's Title Checklist (CTC) but…

Research Findings: The present study investigated the social and cognitive precursors of vocabulary knowledge in 239 Turkish preschoolers both concurrently (Time 1 [T1] Mage = 53.29 months, SD = 10.19) and subsequently 1 year later (Time 2 [T2] Mage = 65.40 months, SD = 10.55). We examined the role of parenting behaviors by focusing on emotional…

Purpose: Children with specific language impairment (SLI) often have vocabulary impairments. This study evaluates longitudinal growth in a latent trait of receptive vocabulary in affected and unaffected children ages 2;6 (years;months) to 21 years and evaluates as possible predictors maternal education, child gender, and nonverbal IQ. Method: A…

This study examines the role of a particular kind of linguistic input--talk about the past and future, pretend, and explanations, that is, talk that is decontextualized--in the development of vocabulary, syntax, and narrative skill in typically developing (TD) children and children with pre- or perinatal brain injury (BI). Decontextualized talk…

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3-4 years old, n = 105), kindergarten (5 years old, n = 97),…
