Research distinguishes three types of arithmetic: exact arithmetic, computational estimation and approximate arithmetic. Little is, however, known about the interrelationship among these three arithmetic skills and the general cognitive and early numeracy skills that underlie these arithmetic skills. The current study investigates this…

Background: Rapid automatised naming (RAN) has been found to predict children's reading and arithmetic abilities. However, the underlying mechanisms for its involvement in the two abilities are not clear. This study examines how RAN shared variances with domain-general and domain-specific abilities in predicting reading and arithmetic in Chinese…

Background: Phonological processing skills have been found to contribute to spelling development across different orthographies; however, less is known about the role of orthographic knowledge. This longitudinal study explores the contribution of phonological and orthographic knowledge to spelling development in a semi-transparent orthography…

Background: Word reading and linguistic comprehension skills are two crucial components in reading comprehension, according to the Simple View of Reading (SVR). Some researchers have posited that a third component should be involved in reading and understanding texts, namely executive function (EF) skills. Aim: This study was novel in two ways.…

Although research on cognitive correlates of spelling has been conducted, these studies generally do not distinguish between different types of targets that need to be spelled. Arguably, the contributions of these skills differ for words opposed to pseudowords and for targets that can be spelled on the basis of phoneme-to-grapheme conversion…

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…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

The measurement of self-regulation in young children has been a topic of great interest as researchers and practitioners work to help ensure that children have the skills they need to succeed as they start school. The present study examined how a revised version of a commonly used measure of behavioral self-regulation, the…

The present five-year longitudinal study from preschool to grade 3 examined the developmental associations among oral language comprehension, task orientation, reading precursors, and reading fluency, as well as their role in predicting grade 3 reading comprehension. Ninety Finnish-speaking students participated in the study. The students' oral…

Purpose: This study investigated the relative utility of linguistic and nonlinguistic processing speed tasks as predictors of language impairment (LI) in children across 2 time points. Method: Linguistic and nonlinguistic reaction time data, obtained from 131 children (89 children with typical development [TD] and 42 children with LI; 74 boys and…

Guided primarily by life history theory, this study was designed to identify how and why early exposure to caregiver intimate relationship instability uniquely predicts children's externalizing symptoms in the context of other dimensions of unpredictability characterized by residential and parental job transitions. Participants included 243…

Purpose: The purpose of this study was to retrospectively examine the preschool language and early literacy skills of kindergarten good and poor readers, and to determine the extent to which these skills predict reading status. Method: Participants were 136 children with language impairment enrolled in early childhood special education classrooms.…

Children's behavioral self-regulation and executive function (EF; including attentional or cognitive flexibility, working memory, and inhibitory control) are strong predictors of academic achievement. The present study examined the psychometric properties of a measure of behavioral self-regulation called the Head-Toes-Knees-Shoulders (HTKS) by…

This study assessed 562 four-year-old children at the beginning and end of their prekindergarten (pre-k) year and followed them to the end of kindergarten. At each time point children were assessed on 6 measures of executive function (EF) and 5 subtests of the Woodcock-Johnson III academic achievement battery. Exploratory factor analyses yielded…

Research Findings: Several recent studies carried out in the United States and abroad (i.e., Asia and Europe) have demonstrated that the ability of young children to regulate their behavior (including inhibitory control, working memory, attentional control) significantly predicts their academic achievement. The current study examined the…
