With a focus on within-person effects, this study investigated mutualism among academic skills (reading, math, science) and between those skills and verbal working memory in a general population sample and groups with high or low skills from Grades 2 to 5 (2010-2016, N = 859-9040, age 6.27-13.13 years, 49% female, ethnically diverse). Mutualism…

We studied the role of sensorimotor and working memory systems in supporting development of perceptual rhythm processing with 119 participants aged 7-12 years. Children were assessed for their abilities in sensorimotor synchronization (SMS; beat tapping), auditory working memory (AWM; digit span), and rhythm discrimination (RD; same/different…

Performance on a range of spatial and mathematics tasks was measured in a sample of 1592 students in kindergarten, third grade, and sixth grade. In a previously published analysis of these data, performance was analyzed by grade only. In the present analyses, we examined whether the relations between spatial skill and mathematics skill differed…

With a focus on within-person effects, this study investigated mutualism among academic skills (reading, math, science) and between those skills and verbal working memory in a general population sample and groups with high or low skills from Grades 2 to 5 (2010-2016, N = 859-9040, age 6.27-13.13 years, 49% female, ethnically diverse).

'Should I talk to my child in a language that I am not good at?' This question reveals the dilemma that many bilingual parents are facing. In the current study, 301 English-Mandarin bilinguals' mothers in Singapore self-evaluated their Mandarin proficiency and we assessed the 4-5 years old children's Mandarin receptive vocabulary and grammar. We…

Spatial skills have been consistently linked to mathematics achievement in older students and adults, but we know little about their relationship to mathematics achievement in elementary school. This study examined how spatial skills influenced the development of number sense, and subsequent mathematics competency, as students progressed from the…

For young children, sleep is essential for healthy development. Inadequate sleep can affect emotional, behavioural, cognitive, and health outcomes. Low family income and resources can put children at risk for poor sleep quality, impairing their subsequent cognitive abilities. The current study examined low socioeconomic status (SES) as a factor…

This study examines how gains in mathematics achievement are related to executive processing functions and student sociodemographic characteristics across schools' national representative longitudinal sample of children in kindergarten (K) followed through grade four in the Early Childhood Longitudinal Study of 2010. Mathematics trajectories were…

Social mastery motivation and parental response are important correlates of children's vocabulary and self-regulation skills, but little research has examined their relationships collectively. This study investigated the direct relationships among social mastery motivation (active interaction and positive affect frequencies), parental response,…

This study investigated the relationship between balanced multilingualism and working memory. Specifically, it reports on the relationship between balanced proficiency in speaking, reading and comprehension (across three languages), and verbal and visuospatial working memory in young South African adults. Information about participants' language…

The purpose of this longitudinal study was to examine whether young learners of varying reading and spelling performance, identified in Grade 2, can be distinguished retrospectively from kindergarten, based on their growth profiles in cognitive (planning, attention, working memory--WM) and linguistic (phonological--PA and naming speed--RAN)…

An enduring challenge in visual-spatial research has been to identify the factors contributing to individual differences in ability. This research investigated the overall, verbal, and nonverbal visual-spatial ability of 61 (34 boys) three- to five-year-olds (M[subscript age] = 57.3 months; SD = 7.9) and the following factors known to be related…

Through five waves of data collection, this longitudinal study investigated the development of spatial skills in 304 elementary school children (M[subscript age] = 7.64 years) as they progressed from the second to fourth grade. The study focused on whether multiple latent classes with different developmental profiles best explain development.…

Pierce "et al." (2017) have proposed that variations in the timing, quality and quantity of language input during the earliest stages of development are related to variations in the development of phonological working memory and, in turn, to later language learning outcomes. To examine this hypothesis, three groups of children who are…

Executive function skills have a direct link to reading comprehension (Carretti, Borella, Cornoldi, & De Beni, 2009). Specifically, cognitive flexibility and working memory have been shown as a significant contributor to reading comprehension (Cain, Oakhill, & Bryant, 2004; Cartwright, 2002). Understanding the link between cognitive…
