School Readiness Predictors of Early Academic Achievement in Children Born Very Preterm

OBJECTIVE

This study examined associations of school readiness measures obtained before school entry with academic achievement at early school age in children born very preterm (VPT, gestational age ≤ 30 weeks) and children born full term (FT, GA ≥ 37 weeks).

METHOD

The sample included 38 children born VPT and 30 born FT recruited at age 4 years and followed to early school age. Measures of readiness included tests of global cognition, executive function, motor abilities, and preacademic skills, as well as caregiver behavior ratings. Tests of math, reading, and spelling were administered to assess school-age achievement. Analyses that controlled for socioeconomic status and accounted for inclusion of siblings compared the groups on the achievement tests and identified measures of readiness related to school-age achievement.

RESULTS

Achievement difficulties were more pronounced in the VPT group and associated with problems in multiple readiness domains. Effect sizes for these associations were largest for measures of spatial ability, executive function, and preacademic skills. Some associations remained significant when controlling for global cognitive ability at age 4 years, and others were significant only for the VPT group.

CONCLUSION

Findings suggest that deficits on tests in multiple readiness domains assessed before school entry in children born VPT or FT are associated with early school-age achievement. The most pronounced readiness deficits in the VPT group at age 4 years were also among those most closely associated with later difficulties in achievement. Further research is needed to refine assessment of school readiness in children born VPT.

Sex differences in brain-behavior relationships in the first two years of life

Background

Evidence for sex differences in cognition in childhood is established, but less is known about the underlying neural mechanisms for these differences. Recent findings suggest the existence of brain-behavior relationship heterogeneities during infancy; however, it remains unclear whether sex underlies these heterogeneities during this critical period when sex-related behavioral differences arise.

Methods

A sample of 316 infants was included with resting-state functional magnetic resonance imaging scans at neonate (3 weeks), 1, and 2 years of age. We used multiple linear regression to test interactions between sex and resting-state functional connectivity on behavioral scores of working memory, inhibitory self-control, intelligence, and anxiety collected at 4 years of age.

Results

We found six age-specific, intra-hemispheric connections showing significant and robust sex differences in functional connectivity-behavior relationships. All connections are either with the prefrontal cortex or the temporal pole, which has direct anatomical pathways to the prefrontal cortex. Sex differences in functional connectivity only emerge when associated with behavior, and not in functional connectivity alone. Furthermore, at neonate and 2 years of age, these age-specific connections displayed greater connectivity in males and lower connectivity in females in association with better behavioral scores.

Conclusions

Taken together, we critically capture robust and conserved brain mechanisms that are distinct to sex and are defined by their relationship to behavioral outcomes. Our results establish brain-behavior mechanisms as an important feature in the search for sex differences during development.

Socio-Economic and Cultural Context in the Development of Early Mathematical Competencies: A Comparative Study of Specific Educational Contexts in Chile and Spain

This research presents the findings of a comparative study of mathematical competence among 130 students (M = 54.08 months; SD = 2.57) from vulnerable school contexts in Chile and the Spanish public school system. The study analyses a set of general and specific domain precursors for which evidence of socioeconomic background exists. Using multivariate regression and discriminant analysis techniques, we calculated similarities and differences between groups by comparing these precursors. Significant differences were found between the Spanish and Chilean groups (p < .05); however, no differences were observed in non-symbolic comparison and receptive vocabulary. Possible reasons for the existence and extent of these differences are discussed in terms of socio-cultural and educational contexts.

Effects of a Portuguese social-emotional learning program on the competencies of elementary school students

Introduction

It is widely recognized that socio-emotional learning (SEL) interventions can contribute to supporting students' positive development of socio-emotional skills (SES) and positive relationships with peers and teachers. Thus, interest in promoting students' SES through universal evidence-based programs is spreading around the world, including in Portuguese schools.

Methods

This quasi-experimental study examines the efficacy of a SEL classroom-based program, infused into the curriculum, on students' communication, self-regulation, and classroom peer relationships. Participants included 208 third- to fourth-grade students from three Portuguese public elementary schools: 143 in the intervention group (54.5% boys; M_age = 8.72; SD = 0.61); 65 in the comparison group (52.3% boys; M_age = 8.66; SD = 0.59). Measures included: Study on Social and Emotional Skills, parent, child, and teacher versions; and Classroom Peer Context Questionnaire, completed by students. The study followed a pre- and post-test design, with a 16-week intervention.

Results

For the overall participants, results show a positive effect of the program on students' assertiveness (family report), peer conflict and peer cooperation. Effects were analyzed separately by school grade. A statistically significant positive effect of the program on third-grade students' assertiveness and sociability was found. For fourth-grade students, a positive effect was found on - emotional control). classroom conflicts, isolation, cooperation and cohesion behaviors.

Discussion

These positive effects support the expansion of universal interventions when aiming at strengthening SEL in Portuguese school settings, underlining the relevance of embedding SEL into the curricula and daily practices at schools.

Prevalence and functional impact of social (pragmatic) communication disorders

BACKGROUND

The aim of this study was to evaluate the Children's Communication Checklist-2 (CCC-2) for measuring social-pragmatic communication deficits and to ascertain their prevalence and functional impact in a community sample.

METHODS

We used parent and teacher responses to the CCC-2 to approximate inclusion (poor social-pragmatic skills) and exclusion (poor structural language skills or autistic symptomatology) criteria for social (pragmatic) communication disorder (SPCD). We tested the prevalence of social-pragmatic deficits in a population-based sample of children (n = 386) aged 5-6 years old using CCC-2 algorithms. We also investigated the academic and behavioural profiles of children with broadly defined limitations in social-pragmatic competence on the CCC-2.

RESULTS

Regardless of the diagnostic algorithm used, the resulting prevalence rates for social-pragmatic deficits indicated that very few children had isolated social-communication difficulties (0-1.3%). However, a larger proportion of children (range: 6.1-10.5%) had social-pragmatic skills outside the expected range alongside structural language difficulties and/or autism spectrum symptoms, and this profile was associated with a range of adverse academic and behavioural outcomes.

CONCLUSIONS

A considerable proportion of children in the early years of primary school has social-pragmatic deficits that interfere with behaviour and scholastic activity; however, these rarely occur in isolation. Exclusionary criteria that include structural language may lead to underidentification of individuals with social-pragmatic deficits that may benefit from tailored support and intervention.

Vocabulary Learning in Chinese as a Second Language: Exploring the Role of Self-Regulation in Facilitating Vocabulary Knowledge of Second Language Learners

Vocabulary knowledge comprises depth and breadth, which are regarded as important indicators of second language (L2) learning capability. Self-regulation is a key factor in promoting vocabulary knowledge. However, the role and contribution of depth and breadth in and to L2 learning, as well as the predictive role of different factors of self-regulation in depth and breadth, remain unclear. Therefore, this study aims to identify the relationship between vocabulary knowledge and self-regulation by establishing a structural equation model based on exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) using self-regulation and vocabulary knowledge (depth and breadth) questionnaires. A total of 215 Vietnamese university students participated in the research. The results show that Vietnamese university students generally obtain high scores in breadth, but their scores vary in depth, which indicates although most of them can accurately understand some aspects of Chinese word meaning, they are not able to command the form and usage of words. In addition, there is a negative correlation between self-regulation and vocabulary breadth, which demonstrates that high self-regulation, especially emotional control, can affect Vietnamese university students’ vocabulary learning. This study also proposes some suggestions for Chinese vocabulary teaching.

Perceptual Access Reasoning (PAR) in Developing a Representational Theory of Mind

An important part of children's social and cognitive development is their understanding that people are psychological beings with internal, mental states including desire, intention, perception, and belief. A full understanding of people as psychological beings requires a representational theory of mind (ToM), which is an understanding that mental states can faithfully represent reality, or misrepresent reality. For the last 35 years, researchers have relied on false‐belief tasks as the gold standard to test children's understanding that beliefs can misrepresent reality. In false‐belief tasks, children are asked to reason about the behavior of agents who have false beliefs about situations. Although a large body of evidence indicates that most children pass false‐belief tasks by the end of the preschool years, the evidence we present in this monograph suggests that most children do not understand false beliefs or, surprisingly, even true beliefs until middle childhood. We argue that young children pass false‐belief tasks without understanding false beliefs by using perceptual access reasoning (PAR). With PAR, children understand that seeing leads to knowing in the moment, but not that knowing also arises from thinking or persists as memory and belief after the situation changes. By the same token, PAR leads children to fail true‐belief tasks. PAR theory can account for performance on other traditional tests of representational ToM and related tasks, and can account for the factors that have been found to correlate with or affect both true‐ and false‐belief performance. The theory provides a new laboratory measure which we label the belief understanding scale (BUS). This scale can distinguish between a child who is operating with PAR versus a child who is understanding beliefs. This scale provides a method needed to allow the study of the development of representational ToM.

In this monograph, we report the outcome of the tests that we have conducted of predictions generated by PAR theory. The findings demonstrated signature PAR limitations in reasoning about the mind during the ages when children are hypothesized to be using PAR. In Chapter II, secondary analyses of the published true‐belief literature revealed that children failed several types of true‐belief tasks.

Chapters III through IX describe new empirical data collected across multiple studies between 2003 and 2014 from 580 children aged 4–7 years, as well as from a small sample of 14 adults. Participants were recruited from the Phoenix, Arizona metropolitan area. All participants were native English‐speakers. Children were recruited from university‐sponsored and community preschools and daycare centers, and from hospital maternity wards. Adults were university students who participated to partially fulfill course requirements for research participation. Sociometric data were collected only in Chapter IX, and are fully reported there.

In Chapter III, minor alterations in task procedures produced wide variations in children's performance in 3‐option false‐belief tasks. In Chapter IV, we report findings which show that the developmental lag between children's understanding ignorance and understanding false belief is longer than the lag reported in previous studies. In Chapter V, children did not distinguish between agents who have false beliefs versus agents who have no beliefs. In Chapter VI, findings showed that children found it no easier to reason about true beliefs than to reason about false beliefs. In Chapter VII, when children were asked to justify their correct answers in false‐belief tasks, they did not reference agents’ false beliefs. Similarly, in Chapter VIII, when children were asked to explain agents’ actions in false‐belief tasks, they did not reference agents’ false beliefs. In Chapter IX, children who were identified as using PAR differed from children who understood beliefs along three dimensions—in levels of social development, inhibitory control, and kindergarten adjustment.

Although the findings need replication and additional studies of alternative interpretations, the collection of results reported in this monograph challenges the prevailing view that representational ToM is in place by the end of the preschool years. Furthermore, the pattern of findings is consistent with the proposal that PAR is the developmental precursor of representational ToM. The current findings also raise questions about claims that infants and toddlers demonstrate ToM‐related abilities, and that representational ToM is innate.

Teaching Vocabulary to Improve Print Knowledge in Preschool Children with Hearing Loss

Purpose

The purpose of this article was to examine evidence that (a) published measures may tap different categories of print knowledge and result in disparate findings in the literature, (b) concept vocabulary knowledge in children with hearing loss may exacerbate deficits in conceptual print knowledge, and (c) concept vocabulary can be taught via direct instruction for preschool children with hearing loss.

Method

In Study 1, an item analysis of published print knowledge measures was performed to determine the prevalence of concept vocabulary in test items. Additionally, the performance on a conceptual print knowledge measure was compared for preschool children with and without hearing loss. In Study 2, four preschool children participated in a multiple probe across behaviors treatment design to determine if concept vocabulary could be explicitly taught to children with hearing loss.

Results

Differences emerged in use of concept vocabulary on test items across the measures, which may explain disparate findings that have been reported in this area. Additionally, children with hearing loss performed lower than children with typical hearing on items that contained concept vocabulary but not on items that did not. Finally, we found initial evidence that direct instruction can improve concept vocabulary for children with hearing loss, and it might not be necessary to separately target each concept category.

Conclusion

This series of studies lays groundwork for future research confirming a connection between conceptual print knowledge and conceptual vocabulary knowledge, and offers evidence for intervention that could be used clinically to teach conceptual vocabulary.

Sustained Benefits of a Preschool Home Visiting Program: Child Outcomes in Fifth Grade

This study evaluated the sustained effects of the Research-based Developmentally Informed Parent program (REDI-P) at fifth grade, six years after intervention. Participants were 200 prekindergarten children attending Head Start (55% White, 26% Black, 19% Latinx, 56% male, mean age of 4.45 years at study initiation) and their primary caregivers, who were randomly assigned to a control group or a 16-session home-visiting intervention that bridged the preschool and kindergarten years. In addition, the study explored moderation of sustained effects by parenting risks (e.g., less than high-school education, single-parent status, parental depression, and low parent-child warmth). Growth curves over the course of the elementary years examined outcomes in three domains: child academic performance, social-emotional adjustment, and parent-child functioning. At fifth grade, significant main effects for intervention were sustained in the domains of academic performance (e.g., reading skills, academic motivation, and learning engagement) and parent-child functioning (e.g., academic expectations and parenting stress). Significant moderation by parenting risk emerged on measures of social-emotional adjustment (e.g., social competence and student-teacher relationships); parenting risk also amplified effects on some measures of academic performance and parent-child functioning, with larger effects for children from families experiencing fewer risks. Implications are discussed for the design of preschool home visiting programs seeking to enhance the school success and social-emotional well-being of children living in poverty.

Promoting resilience: A preschool intervention enhances the adolescent adjustment of children exposed to early adversity

Two hundred ninety-four children from low-income families (58% White, 17% Latinx, 25% Black; 54% girls; Mage = 4.49 years old at study entry) were recruited from Head Start classrooms to participate in a randomized-controlled trial of the project Research-based, Developmentally Informed (REDI) preschool intervention and then followed longitudinally for 10 years through 9th grade. At study entry, parents reported on their children's exposure to adverse childhood experiences (ACEs). Youth reported on their feelings of social-emotional distress and school bonding after making the transition into middle school (7th grade) and high school (9th grade). Multilevel latent profile analyses revealed three profiles of adolescent distress and school bonding. Increased rates of ACEs in early childhood predicted membership in adolescent profiles characterized by heightened social-emotional distress and reduced levels of school bonding. The REDI intervention that focused on promoting early social-emotional and language skills in preschool moderated the impact of early ACEs on adolescent adjustment and promoted youth resilience, significantly buffering children from the negative impact of early ACEs on their levels of social-emotional distress and school bonding.
