A translational application of music for preschool cognitive development: RCT evidence for improved executive function, self-regulation, and school readiness.

The benefits of active music participation and training for cognitive development have been evidenced in multiple studies, with this link leveraged in music therapy approaches with clinical populations. Although music, rhythm, and movement activities are widely integrated into children's play and early education, few studies have systematically translated music therapy-based approaches to a nonclinical population to support early cognitive development. This study reports the follow-up effects of the Rhythm and Movement for Self Regulation (RAMSR) program delivered by generalist preschool teachers in low socioeconomic communities. This randomized control trial (RCT) involved 213 children across eight preschools in disadvantaged communities in Queensland, Australia. The intervention group received 16-20 sessions of RAMSR over 8 weeks, while the control group undertook usual preschool programs. Primary outcome measures included executive function (child assessment of shifting, working memory, and inhibition) and self-regulation (teacher report), with secondary outcomes of school readiness and visual-motor integration. Data were collected pre- and post-intervention, and again 6 months later once children had transitioned into school. Results demonstrated significant intervention effects across the three time points for school readiness (p = 0.038, ηp 2  = 0.09), self-regulation (p < 0.001, ηp 2  = 0.08), and inhibition (p = 0.002 ηp 2  = 0.23). Additionally, the feasibility of building capacity in teachers without any music background to successfully deliver the program was evidenced. These findings are important given that children from low socioeconomic backgrounds are more likely to need support for cognitive development yet have inequitable access to quality music and movement programs. RESEARCH HIGHLIGHTS: Initial effects of self-regulation from a rhythm and movement program were sustained following transition into school for children from disadvantaged backgrounds. Delayed effects of inhibition and school readiness from a rhythm and movement program appeared 6 months post-intervention as children entered school. Generalist teachers can successfully implement a rhythm and movement program, which boosts critical developmental cognitive skills.

Vision and academic performance in primary school children.

PURPOSE: Vision is considered important for academic performance in children; however, the evidence in this area tends to be inconsistent and inconclusive. This study explored the association between vision function and visual information processing measures and standardised academic achievement scores in Grade 3 Australian children. METHODS: Participants included 108 Grade 3 primary school children (M = 8.82 ± 0.32 years) from three state primary schools in South-East Queensland. All participants underwent a standard vision screening, including distance visual acuity (VA), binocular vision testing and stereoacuity (SA). A computer-based battery of visual information processing tests including the Development Eye Movement (DEM) test, Visual Sequential Memory (VSM) and Symbol Search (SS) was also administered. Australian National Assessment Program for Literacy and Numeracy (NAPLAN) scores across five subtests of academic performance were obtained for each child: Reading, Writing, Spelling, Grammar/Punctuation and Numeracy. RESULTS: The DEM adjusted horizontal and vertical times were most strongly associated with all of the NAPLAN subtest scores (p < 0.01), adjusted for age and the socio-economic status of the school; the DEM ratio was not significantly associated with any of the NAPLAN subtests. VSM and SS scores were significantly associated with one or more NAPLAN subtests, as were worse and better eye VA; SA showed no significant association with any of the NAPLAN subtests. CONCLUSIONS: Performance on the horizontal and vertical DEM subtests was most strongly associated with academic performance. These data, in conjunction with other clinical data, can provide useful information to clinicians regarding their prescribing and management philosophy for children with lower levels of uncorrected refractive error and binocular vision anomalies.

Schools' readiness for child sexual abuse prevention education: Preliminary scale development using a Delphi method.

BACKGROUND: This study employed a Delphi method with a panel of experts to collaboratively design a new instrument to assess schools' readiness for school-based child sexual abuse prevention education. METHODS: An initial item pool was generated based on a review of existing empirical research and theoretical models. We invited researchers and stakeholders in the field of child sexual abuse prevention as experts to participate in a two-round online Delphi study in which they rated item importance and clarity, contributed their views on superfluous and/or missing items, gave rephrasing suggestions, and re-appraised revised items. Following the Delphi study, the instrument was pilot tested with a convenience sample of school staff. RESULTS: The initial item pool comprised 81 items in five construct sub-scales congruent with Wiener's Organizational Readiness for Change theory: contextual factors, informational assessment, change valence, change commitment, and change efficacy. In the Delphi study, 24 experts participated in round 1, and 13 participated in round 2. Based on Delphi study responses, the instrument was reduced to 56 items in the five construct subscales: contextual factors (28 items), informational assessment (13 items), change valence (6 items), change commitment (3 items), and change efficacy (6 items). The Schools' Readiness for Child Sexual Abuse Prevention Education (SR-CSAPE) was successfully pilot tested with school staff (n = 19) and minor changes to demographic items were incorporated. CONCLUSIONS: Informed by experts, the Schools' Readiness for Child Sexual Abuse Prevention Education (SR-CSAPE) is a newly-developed 56-item scale that identifies key organizational dimensions to schools' preparedness for CSA prevention education. Psychometric properties of the scale must be determined in future research.

Early Childhood Screen Use Contexts and Cognitive and Psychosocial Outcomes: A Systematic Review and Meta-analysis.

Importance: The multifaceted nature of screen use has been largely overlooked in favor of a simplistic unidimensional measure of overall screen time when evaluating the benefits and risks of screen use to early childhood development. Objective: To conduct a systematic review and meta-analysis to examine associations of screen use contexts in early childhood with cognitive and psychosocial outcomes. Data Sources: PsycINFO, Embase, MEDLINE Ovid, ProQuest, CINAHL, Web of Science, and Scopus were searched from inception to December 31, 2023. Study Selection: A total of 7441 studies were initially identified. Studies were included if they examined associations between a contextual factor of screen use among children aged 0 to 5.99 years and cognitive or psychosocial development. Observational, experimental, and randomized clinical trial study designs were included. Data Extraction and Synthesis: All studies were independently screened in duplicate following PRISMA guidelines. Effect sizes of associations (r) from observational studies were pooled using random-effects 3-level meta-analyses. The remaining study designs were narratively synthesized. Main Outcomes and Measures: Screen use contexts included content (child directed and age inappropriate), type (program viewing and game or app use), co-use (or solo use), background television, caregiver screen use during child routines, and purpose. Outcomes were cognitive (executive functioning, language, and academic skills) or psychosocial (internalizing and externalizing behavior problems and socioemotional competence). Results: Overall, 100 studies (176 742 participants) were included, and of these, 64 observational studies (pooled sample sizes ranging from 711 to 69 232) were included in meta-analyses. Program viewing (n = 14; k = 48; r, -0.16; 95% CI, -0.24 to -0.08) and background television (n = 8; k = 18; r, -0.10; 95% CI, -0.18 to -0.02) were negatively associated with cognitive outcomes, while program viewing (n = 6; k = 31; r, -0.04; 95% CI, -0.07 to -0.01), age-inappropriate content (n = 9; k = 36; r, -0.11; 95% CI, -0.17 to -0.04), and caregiver screen use during routines (n = 6; k = 14; r, -0.11; 95% CI, -0.20 to -0.03) were negatively associated with psychosocial outcomes. Co-use was positively associated with cognitive outcomes (n = 8; k = 28; r, 0.14; 95% CI, 0.03 to 0.25). Conclusions and Relevance: Findings show small to moderate effect sizes that highlight the need to consider screen use contexts when making recommendations for families, clinicians, and educators beyond screen time limits; including encouraging intentional and productive screen use, age-appropriate content, and co-use with caregivers.

Representational change and strategy use in children's number line estimation during the first years of primary school.

BACKGROUND: The objective of this study was to scrutinize number line estimation behaviors displayed by children in mathematics classrooms during the first three years of schooling. We extend existing research by not only mapping potential logarithmic-linear shifts but also provide a new perspective by studying in detail the estimation strategies of individual target digits within a number range familiar to children. METHODS: Typically developing children (n = 67) from Years 1-3 completed a number-to-position numerical estimation task (0-20 number line). Estimation behaviors were first analyzed via logarithmic and linear regression modeling. Subsequently, using an analysis of variance we compared the estimation accuracy of each digit, thus identifying target digits that were estimated with the assistance of arithmetic strategy. RESULTS: Our results further confirm a developmental logarithmic-linear shift when utilizing regression modeling; however, uniquely we have identified that children employ variable strategies when completing numerical estimation, with levels of strategy advancing with development. CONCLUSION: In terms of the existing cognitive research, this strategy factor highlights the limitations of any regression modeling approach, or alternatively, it could underpin the developmental time course of the logarithmic-linear shift. Future studies need to systematically investigate this relationship and also consider the implications for educational practice.

Visual information processing skills are associated with academic performance in Grade 2 school children.

PURPOSE: This study evaluated the association between performance on visual information processing tests and academic performance in school children. METHODS: Visual-motor integration (VMI), the Developmental Eye Movement (DEM) test, visual acuity and stereoacuity were assessed in 222 Grade 2 children (mean age: 7.90 ± 0.33 years). Academic performance was assessed using standardized tests of reading and mathematics (PAT-R and PAT-M). Linear regression analyses examined associations between visual information processing (VMI and DEM) and academic measures, adjusting for school socio-economic background and age. Receiver operating characteristic (ROC) analysis was used to assess the ability of the tests to identify children with below average academic performance. RESULTS: Visual-motor integration (VMI) and DEM (horizontal time) were most strongly associated with PAT-R and PAT-M. Linear regression models explained 28.6% of variance in PAT-R (VMI: standardized regression coefficient = 0.31, p < 0.01; DEM horizontal time: -0.28, p < 0.01) and 24.1% of variance in PAT-M (VMI: standardized regression coefficient = 0.29, p < 0.01; DEM horizontal time: -0.16, p = 0.02). Receiver operating characteristic (ROC) curve analysis indicated that VMI was most strongly associated with below average PAT-R (area under curve [AUC] of 0.74 [95% CI: 0.67-0.81]) and PAT-M (AUC of 0.73 [95% CI: 0.66-0.81]). CONCLUSION: Visual-motor integration (VMI) was most strongly associated with reading and mathematics scores in school children. A child's academic performance can be an important factor in their optometric management. The ability of clinical tests to identify children at risk of underachieving academically provides additional support to clinicians in managing their patients.

Executive Function in Adolescence: Associations with Child and Family Risk Factors and Self-Regulation in Early Childhood.

Executive functions are important higher-order cognitive skills for goal-directed thought and action. These capacities contribute to successful school achievement and lifelong wellbeing. The importance of executive functions to children's education begins in early childhood and continues throughout development. This study explores contributions of child and family factors in early childhood to the development of executive function in adolescence. Analyses draw on data from the nationally representative study, Growing up in Australia: The Longitudinal Study of Australian Children. Participants are 4819 children in the Kindergarten Cohort who were recruited at age 4-5 years. Path analyses were employed to examine contributions of early childhood factors, including family socio-economic position (SEP), parenting behaviors, maternal mental health, and a child behavioral risk index, to the development of executive function in adolescence. The influence of children's early self-regulatory behaviors (attentional regulation at 4-5 years and approaches to learning at 6-7 years) were also taken into account. A composite score for the outcome measure of executive function was constructed from scores on three Cogstate computerized tasks for assessing cognition and measured visual attention, visual working memory, and spatial problem-solving. Covariates included child gender, age at assessment of executive function, Aboriginal and Torres Strait Islander status, speaking a language other than English at home, and child's receptive vocabulary skills. There were significant indirect effects involving child and family risk factors measured at 4-5 years on executive function at age 14-15 years, mediated by measures of self-regulatory behavior. Child behavioral risk, family SEP and parenting behaviors (anger, warmth, and consistency) were associated with attentional regulation at 4-5 years which, in turn, was significantly associated with approaches to learning at 6-7 years. Both attentional regulation and approaches to learning were directly associated with executive functioning at 14-15 years. These findings suggest that children's early self-regulatory capacities are the basis for later development of executive function in adolescence when capabilities for planning and problem-solving are important to achieving educational goals.

Symbolic number: the integration of magnitude and spatial representations in children aged 6 to 8 years.

The process of learning symbolic Arabic digits in early childhood requires that magnitude and spatial information integrates with the concept of symbolic digits. Previous research has separately investigated the development of automatic access to magnitude and spatial information from symbolic digits. However, developmental trajectories of symbolic number knowledge cannot be fully understood when considering components in isolation. In view of this, we have synthesized the existing lines of research and tested the use of both magnitude and spatial information with the same sample of British children in Years 1, 2, and 3 (6-8 years of age). The physical judgment task of the numerical Stroop paradigm demonstrated that automatic access to magnitude was present from Year 1 and the distance effect signaled that a refined processing of numerical information had developed. Additionally, a parity judgment task showed that the onset of the spatial-numerical association of response codes effect occurs in Year 2. These findings uncover the developmental timeline of how magnitude and spatial representations integrate with symbolic number knowledge during early learning of Arabic digits and resolve inconsistencies between previous developmental and experimental research lines.
