Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated…

Research Findings: Promoting inhibitory control in preschoolers could increase the likelihood of positive developmental trajectories. Nevertheless, to date only a limited number of studies have focused on inhibitory control training, reporting mixed results. To examine the efficacy and the transfer effects of the training on preschoolers, seven…

The purpose of this experimental study was to examine the contribution of phoneme awareness training and orthography to the learning of new vocabulary words by partial alphabetic phase readers. Hypotheses included: Preschoolers taught to phonemically segment words with letters would outperform those trained without letters on an invented spelling…

The present study investigated the longitudinal effects of early exposure to L2-English on L1-Turkish language competence, narrative skills and executive functioning. We asked whether early immersion-like exposure to L2, starting around 3 years of age, would have reflections on L1 competence, L1 narrative skills and gains in cognitive flexibility.…

Beginning with the 2015-2016 school year, the West Virginia Department of Education (WVDE) partnered with the National Institute for Early Education Research (NIEER) and Marshall University to conduct a five-year study of the quality of the West Virginia Universal Pre-K (WV Pre-K) program. The study was designed to examine the effectiveness of the…

Executive functions (EFs) and intelligence were examined concurrently and longitudinally in 126 preschool children. EF was assessed using the Flexible Item Selection Task (FIST) and the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Children's intelligence was assessed using the Verbal and Performance subtests from…

A classroom randomized trial (n = 31 classrooms) was conducted using the Second Step Early Learning (SSEL) curriculum compared to usual curricula. Head Start and community preschool classrooms enrolling low income children were randomly assigned to deliver SSEL (n = 16) or usual curricula (n = 15). Data are reported for four year olds…

The purpose of this study was to investigate the influence of digital and non-digital storybooks on low-income preschoolers' oral language comprehension. Employing a within-subject design on 38 four-year-olds from a Head Start program, we compared the effect of medium on preschoolers' target words and comprehension of stories. Four digital…

The present study aims to examine whether the inhibitory processes and impulsive-cognitive style can influence the emergence of coordination level among 61 children aged 3 to 5 years. Luria's tapping tasks, Day-Night tasks, Hand-Candle tasks, Go-NoGo tasks and the Trail Making Tests of Reitan, all involving inhibitory processes, were conducted.…

According to the mental-state reasoning model of suggestibility, 2 components of theory of mind mediate reductions in suggestibility across the preschool years. The authors examined whether theory-of-mind performance may be legitimately separated into 2 components and explored the memory processes underlying the associations between theory of mind…

This study examined the independence and interplay between cognitive risk factors (poor executive function/emotion understanding) and maternal risk factors (low education/high depression) for preschool problem behaviors, indexed by multi-measure, multi-informant (mother/teacher/ researcher) ratings. A socio-economically diverse sample of 235…

Self-regulation, or the ability to control one's actions and responses, is essential for healthy development across varied contexts. Self-regulation comes in several forms, including emotional, behavioral, and cognitive. The present study sought to examine whether individual differences in one form of self-regulation was related to children's…

Mental state language during conversations about the past was assessed in a short-term longitudinal study. Twenty-one mother-child dyads discussed several previously experienced events when the children were 30 and 42 months old. Over time, children's mental term use--although quite low--did increase, and both mothers and children talked more…

Three- and 4-year-old children were tested using videos of puppets in various versions of a theory of mind change-of-location situation, in order to answer several questions about what children are doing when they pass false belief tests. To investigate whether children were guessing or confidently choosing their answer to the test question, a…
