The negative health effects of cigarette smoking during pregnancy (SDP) on the foetus are well known. Despite previous reports of poor cognitive performance in offspring exposed to SDP, few studies specifically consider language outcomes according to maternal smoking. In this study, we systematically review the literature to assess the…

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development. Yet, little is known about how to best characterize interindividual differences in hormone concentrations. The goal of the current study was to examine the antecedents and consequences of membership in empirically derived…

Literacy exposure checklists that assess parental picture book knowledge (Parental Title Checklist [PTC] and Parental Author Checklist [PAC]) have been developed as proxy measures for literacy environments. Although previous research suggests that parental picture book knowledge is a strong predictor of language skills for preschoolers older than…

We aimed to evaluate the validity of the Ages and Stages Questionnaires Edition 3 (ASQ-3) and the MacArthur communicative development inventory (CDI) as a screening measure for children at risk of language development delay in western rural China, by comparing them to the Bayley Scales of Infant and Toddler Development (BSID-III). We administered…

It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self-benefiting lies emerge, and what cognitive factors affect the emergence of self-benefiting lies. To bridge this gap in…

The home numeracy environment (HNE) is often predictive of children's early mathematics skills, though the findings are mixed. Overall, research on kindergarten-aged children demonstrates a relation between the HNE and early numeracy skills, whereas findings for preschool-aged children are more equivocal. One potential reason for equivocality of…

The study examines the concurrent and longitudinal associations between ratings-based measures (parents, secondary caregivers, and observers) and performance-based measures of focused attention in toddlers aged 30 (n = 147), 36 (n = 127), and 42 months (n = 107). Parents and secondary caregivers rated focused attention behaviours using the…

The present study examined the interplay among negative emotionality, responsive parenting and socio-cognitive developmental outcomes (i.e., communication, personal-social and problem-solving outcomes) in about 1620 Korean children using three waves of longitudinal data spanning the first 2 years of their life. Results from the Structural Equation…

The objective of this study was to examine the role of the stimulus material for the prediction of later IQ by early learning measures in the Visual Expectation Paradigm (VExP). The VExP was assessed at 9?months using two types of stimuli, Greebles and human faces. Greebles were assumed to be associated with a higher load on working memory in…

The purpose of this study was to investigate the feasibility and validity of a modified version of Buschke's missing scan methodology, the Missing Scan Task (MST), to assess working memory capacity (WMC) and cognitive control processes in preschool children 3-6?years in age. Forty typically developing monolingual English-speaking children between…

Learning to behave in socially competent ways is an essential component of children's development. This study examined the relations between children's social, communicative, and cognitive skills and their behaviours during a cooperative task, as well as how these relationships change at different ages. Early school-age (5-8 years old) and middle…

This paper examines the relationships among the quality and quantity of parent-child shared book reading (SBR) engagements and children's reading and mathematics outcomes in preschool. Additionally, we explore how child and family characteristics predict the quality and quantity of SBR. Quantity was measured using parental reports of the frequency…

It is argued that self-regulation skill is necessary both for displaying constructive behaviour and for controlling negative social behaviour, and self-regulation might affect social behaviours by increasing the ability to understand others' minds. In this research, in order to examine different aspects of self-regulation and their similarities…

Children who are able to recognize others' emotions are successful in a variety of socioemotional domains, yet we know little about how school-aged children's abilities develop, particularly in the family context. We hypothesized that children develop emotion recognition skill as a function of parents' own emotion-related beliefs,…

More than a century ago, Galton and Spearman suggested that there was a functional relationship between sensory discrimination ability and intelligence. Studies have since been able to confirm a close relationship between general discrimination ability (GDA) and IQ. The aim of the present study was to assess whether this strong relationship…
