Children's distinct drive to reproduce costly rituals.

Costly rituals are ubiquitous and adaptive. Yet, little is known about how children develop to acquire them. The current study examined children's imitation of costly rituals. Ninety-three 4-6 year olds (47 girls, 45% Oceanians, tested in 2022) were shown how to place tokens into a tube to earn stickers, using either a ritualistic or non-ritualistic costly action sequence. Children shown the ritualistic actions imitated faithfully at the expense of gaining stickers; conversely, those shown the non-ritualistic actions ignored them and obtained maximum reward. This highlights how preschool children are adept at and motivated to learn rituals, despite significant material cost. This study provides insights into the early development of cultural learning and the adaptive value of rituals in group cognition.

The School Attachment Monitor-A novel computational tool for assessment of attachment in middle childhood.

BACKGROUND: Attachment research has been limited by the lack of quick and easy measures. We report development and validation of the School Attachment Monitor (SAM), a novel measure for largescale assessment of attachment in children aged 5-9, in the general population. SAM offers automatic presentation, on computer, of story-stems based on the Manchester Child Attachment Story Task (MCAST), without the need for trained administrators. SAM is delivered by novel software which interacts with child participants, starting with warm-up activities to familiarise them with the task. Children's story completion is video recorded and augmented by 'smart dolls' that the child can hold and manipulate, with movement sensors for data collection. The design of SAM was informed by children of users' age range to establish their task understanding and incorporate their innovative ideas for improving SAM software. METHODS: 130 5-9 year old children were recruited from mainstream primary schools. In Phase 1, sixty-one children completed both SAM and MCAST. Inter-rater reliability and rating concordance was compared between SAM and MCAST. In Phase 2, a further 44 children completed SAM complete and, including those children completing SAM in Phase 1 (total n = 105), a machine learning algorithm was developed using a "majority vote" procedure where, for each child, 500 non-overlapping video frames contribute to the decision. RESULTS: Using manual rating, SAM-MCAST concordance was excellent (89% secure versus insecure; 97% organised versus disorganised; 86% four-way). Comparison of human ratings of SAM versus the machine learning algorithm showed over 80% concordance. CONCLUSIONS: We have developed a new tool for measuring attachment at the population level, which has good reliability compared to a validated attachment measure and has the potential for automatic rating-opening the door to measurement of attachment in large populations.

Quality of Life and Participation of Children With Visual Impairment: Comparison With Population Reference Scores.

Purpose: The purpose of this study was to investigate quality of life and participation in children aged 3 to 17 years with visual impairment (VI) compared to reference groups and between subgroups with increasing severity levels of VI. Methods: Parents of children aged 3 to 17 years (n = 500) and children aged 13 to 17 years (n = 75) completed the Child and Adolescent Scale of Participation (CASP). Children aged 7 to 17 years (n = 263) and their parents (n = 255) completed the KIDSCREEN-27 questionnaire to assess quality of life. Scores were compared to age and/or gender-appropriate population-based samples. For the CASP, a comparison was also made with children with chronic conditions or disabilities. The association between severity of VI and quality of life or participation was analyzed with linear regression models. Results: Children reported significantly worse on Physical Wellbeing and Social Support & Peers, but better on the School Environment KIDSCREEN-27 subscales compared to reference groups. Parents additionally reported worse on Autonomy & Parent Relation. Children's participation was significantly worse compared to a population-based sample, but significantly better compared to children with chronic conditions and disabilities. Having moderate or severe VI/blindness was significantly associated with worse participation, as reported by parents relative to those with no VI. Conclusions: Quality of life of children with VI is affected especially regarding Physical Wellbeing and Social Support & Peers compared to a reference population, and their participation is considerably worse. Participation was more affected in children with more severe VI. These results contribute to the understanding of the impact of VI. Interventions targeting physical health, social skills, and participation are warranted.

The correlation between children's own health control and their health perceptions and behaviours, and the associated factors

The study was conducted as a correlational descriptive study to determine the correlation between children's own health control and their health perceptions and behaviours, as well as the associated factors. The sample of the study consisted of 963 children in the age group of 7-12 years studying at one primary schools affiliated with the Ministry of National Education. It was determined that age affected health control and health perception and behaviours in children. A positive significant correlation was found between the health locus of control and health perceptions and behaviours of the children. The children had positive health behaviours, and they had high internal control in their own health management. In accordance with these results, children's own health management should be increased to increase their positive perceptions and behaviours.

Nutritional Quality and Degree of Processing of Children's Foods Assessment on the French Market.

Food packaging marketing techniques which appeal to children (such as cartoon characters and brand mascots) affect children's choices, preferences, and eating habits. Several studies have assessed the nutritional quality of food intended to children in various countries and concluded that most were high in fat, salt, and sugar (HFSS) and ultra-processed foods. The aim of this study is to analyse products intended for children over the age of 3 (foods and beverages with relevant marketing elements on the packaging) available on the French market as regards: (1) nutritional quality, based on the Nutri-Score labelling system, (2) compliance with expected nutritional profile suitable for children, according to the criteria of the WHO Europe Nutrient Profile Model, and (3) degree of processing, as defined by the NOVA classification, from packaging collected in 20 stores (hyper/supermarkets, hard-discount retail chains, and organic food stores). The marketing strategies most often used on children's products are cartoons (97.22%; n = 1120) and mascots (77.78%; n = 896). A total of 1155 products were included in the study, most of which were sugary foods: almost a quarter of the products in the sample (23.81%; n = 275) list a sweetener as the first ingredient, and most of them (89.52%; n = 1034) contain free sugars according to the WHO definition. All the products included in our study feature marketing elements targeting on the packaging, yet 94.88% do not meet the criteria of the WHO Europe Nutrient Profile Model. Most (58.68%; n = 676) belong to Nutri-Score groups D and E, with the highest proportion in group D (39.32%; n = 453) and are ultra-processed (87.97%; n = 1016), especially through the use of flavourings and ultra-processed sugars. Using the Nutri-Score, the WHO Europe Nutrient Profile Model, and the NOVA classification, this study suggests that a significant share of pre-packaged foods marketed to children do not have an adequate nutritional profile. As such, measures are needed to regulate what marketing elements aimed at children can be included on packaging, based on these criteria.

A Psychometric Evaluation of the Motor-Behavioral Assessment Scale for Use as an Outcome Measure in Rett Syndrome Clinical Trials.

Rett syndrome (RTT) is a neurodevelopmental disorder that primarily affects females. Recent work indicates the potential for disease modifying therapies. However, there remains a need to develop outcome measures for use in clinical trials. Using data from a natural history study (n = 1,075), we examined the factor structure, internal consistency, and validity of the clinician-reported Motor Behavior Assessment scale (MBA). The analysis resulted in a five-factor model: (1) motor dysfunction, (2) functional skills, (3) social skills, (4) aberrant behavior, and (5) respiratory behaviors. Item Response Theory (IRT) analyses demonstrated that all items had acceptable discrimination. The revised MBA subscales showed a positive relationship with parent reported items, age, and a commonly used measure of clinical severity in RTT, and mutation type. Further work is needed to evaluate this measure longitudinally and to add items related to the RTT phenotype.

Neighborhood Deprivation Shapes Motivational-Neurocircuit Recruitment in Children.

Implementing motivated behaviors on the basis of prior reward is central to adaptive human functioning, but aberrant reward-motivated behavior is a core feature of neuropsychiatric illness. Children from disadvantaged neighborhoods have decreased access to rewards, which may shape motivational neurocircuits and risk for psychopathology. Here, we leveraged the unprecedented neuroimaging data from the Adolescent Brain Cognitive Development (ABCD) study to test the hypothesis that neighborhood socioeconomic disadvantage shapes the functional recruitment of motivational neurocircuits in children. Specifically, via the ABCD study's monetary-incentive-delay task (N = 6,396 children; age: 9-10 years), we found that children from zip codes with a high Area Deprivation Index demonstrate blunted recruitment of striatum (dorsal and ventral nuclei) and pallidum during reward anticipation. In fact, blunted dorsal striatal recruitment during reward anticipation mediated the association between Area Deprivation Index and increased attention problems. These data reveal a candidate mechanism driving elevated risk for psychopathology in children from socioeconomically disadvantaged neighborhoods.

Using item response theory to evaluate the Children's Behavior Questionnaire: Considerations of general functioning and assessment length.

Although the Children's Behavior Questionnaire (CBQ; Rothbart, Ahadi, Hershey, & Fisher, 2001) is the most popular assessment for childhood temperament, its psychometric qualities have yet to be examined using Item Response Theory (IRT) methods. These methods highlight in detail the specific contributions of individual items for measuring different facets of temperament. Importantly, with 16 scales for tapping distinct aspects of child functioning (195 items total), the CBQ's length can be prohibitive in many contexts. The detailed information about item functioning provided by IRT methods is therefore especially useful. The current study used IRT methods to analyze the CBQ's 16 temperament scales and identify potentially redundant items. An abbreviated "IRT form" was generated based on these results and evaluated across four independent validation samples. The IRT form was compared to the original and short CBQ forms (Putnam & Rothbart, 2006). Results provide fine-grained detail on the CBQ's psychometric functioning and suggest it is possible to remove up to 39% of the original form's items while largely preserving the measurement precision and content coverage of each scale. This study provides considerable psychometric information about the CBQ's items and scales and highlights future avenues for creating even more efficient high-quality temperament assessments.

Clustering of Sedentary Behaviours, Physical Activity, and Energy-Dense Food Intake in Six-Year-Old Children: Associations with Family Socioeconomic Status.

This study examined the clustering of lifestyle behaviours in children aged six years from a prospective cohort study in the Netherlands. Additionally, we analysed the associations between socioeconomic status and the lifestyle behaviour clusters that we identified. Data of 4059 children from the Generation R Study were analysed. Socioeconomic status was measured by maternal educational level and net household income. Lifestyle behaviours including screen time, physical activity, calorie-rich snack consumption and sugar-sweetened beverages consumption were measured via a parental questionnaire. Hierarchical and non-hierarchical cluster analyses were applied. The associations between socioeconomic status and lifestyle behaviour clusters were assessed using logistic regression models. Three lifestyle clusters were identified: "relatively healthy lifestyle" cluster (n = 1444), "high screen time and physically inactive" cluster (n = 1217), and "physically active, high snacks and sugary drinks" cluster (n = 1398). Children from high educated mothers or high-income households were more likely to be allocated to the "relatively healthy lifestyle" cluster, while children from low educated mothers or from low-income households were more likely to be allocated in the "high screen time and physically inactive" cluster. Intervention development and prevention strategies may use this information to further target programs promoting healthy behaviours of children and their families.

Objective Assessment of Temperament in Temperamentally Vulnerable Children: Role in the Studies on Their Stress Levels.

Under conditions of suboptimal parental care, children with specific temperamental features have been shown to be especially vulnerable to the effects of stress. Most studies of temperamentally vulnerable children have been conducted using parental questionnaires, which are unfortunately not completely objective. An alternative approach, the use of objective methods for assessing temperament in childhood, can and should be used to study the impact of poor parenting quality on children's stress levels, an important factor in child development. Although studies using such objective methods exist, they are quite rare. A PubMed search identified twelve articles reviewed here. Existing data indicate that, in general, higher basal cortisol and cortisol stress response are associated with "reactive" temperament: shyness, fearfulness, behavioral inhibition, and negative affectivity. Furthermore, child temperament interacts with the quality of parental care to predict cortisol levels in early childhood. Accordingly, in the context of inadequate parental care, temperamentally vulnerable children with "reactive" temperaments are particularly at risk for negative effects of stress. Studies of stress-by-parental-care-interactions are essential for preventing long-term mental problems and problems with physical health that could occur in temperamentally vulnerable children who receive suboptimal parental care.

Preschool Quality Effects on Learning Behavior and Later Achievement in Germany: Moderation by Socioeconomic Status.

This study investigates whether children's preschool experiences are associated with later achievement via enhanced learning behaviors using data from a German longitudinal study following children (N = 554) from age 3 in preschool to age 8 in second grade. There were two main findings. First, results suggest that more positive learning behaviors at school entry mediate effects of teacher-child interactions in preschool on second-grade achievement. Second, these effects varied by parental socioeconomic status (SES) indicating that low-SES children benefited the most. The findings highlight the role of preschool classroom environments in shaping the school readiness of children with socioeconomic risk factors.

Prenatal and birth predictors of objectively measured physical activity and sedentary time in three population-based birth cohorts in Brazil.

Physical inactivity is a global pandemic with no signs of improvement. Prolonged sitting time is an emerging risk factor that exacerbates the health consequences of physical inactivity. Both behaviours are influenced by various individual and environmental factors but it remains unknown whether early-life exposures "program" these behaviours in later life. The current evidence is limited by a small number of studies which were primarily conducted in high-income countries, and a narrow range of early-life variables examined. Using data from three population-based Brazilian birth cohorts (analytical samples: n = 2740 for 1982 cohort, aged 30 years; n = 3592 for 1993 cohort, aged 18; n = 2603 for 2004 cohort, aged 6), we show that being female and higher family socioeconomic status at birth are strong and consistent predictors of lower physical activity and higher sedentary time from childhood to adulthood. Meanwhile, higher birth weight and lower birth order may also predict lower physical activity and higher sedentary time. Our findings are distinct from evidence from high-income countries, suggesting the importance of broader socioeconomic context in determining individual's activity patterns through the life- course. Such evidence is essential for understanding the biological etiology and socioeconomic context of physical activity and sedentary behaviour at an early stage in life.

Cumulative Sociodemographic Risk Indicators for Difficult Child Temperament.

Cumulative risk models provide a convenient, parsimonious way to identify outcomes associated with multiple, highly correlated risk factors. In this paper, we explored linkages between a cumulative sociodemographic risk index, which included rurality status, and aspects of temperamental difficulty in an early school age sample of 53 school-aged children from Southcentral Appalachia. Cumulative risk was significantly predictive of temperamental difficulty, as defined by high negative affectivity and low effortful control, but post-hoc analyses revealed this association to be driven primarily by two of the eight risk indicators: rural status and income-to-needs risk. Although rurality status was highly correlated with income-to-needs risk, rurality predicted negative affectivity over and above income-to-needs risk and income-to-needs risk predicted effortful control over and above rurality status. Future models of cumulative risk may benefit from including rurality status as a risk indicator, despite high collinearity with income-to-needs risk.

Socio-Demographic Variation, Perceived Oral Impairment and Oral Impact on Daily Performance among Children in Saudi Arabia.

Background: This study aimed to describe the oral impact (estimate, severity, frequency) on daily performance (e.g., eating, speaking) and identify the potential perceived oral impairment(s) and socio-behavioral factors associated with oral impact, namely presence or absence of oral impact, among children aged 9-12 years old in Al-Madinah Al-Munawwarah, Saudi Arabia. Methods: A cross-sectional convenience sample of 186 children aged 9-12 years old was recruited. Sociodemographic characteristics, oral health-related behaviors, and perceived oral impairments (e.g., caries, toothache) were obtained from participants. The validated Arabic Child Oral Impact on Daily Performance (C-OIDP) inventory was used to assess oral impacts. Sample descriptive statistics and multivariable logistic regressions modeling the association between C-OIDP and explanatory variables were performed. Results: The mean (±SD) age of the children was 10.29 ± 1.24 years, 66.4% were from public schools, and 52% were females. At least one C-OIDP was reported by 78% of the participants. The mean C-OIDP score was 2.27 ± 1.99. Toothache was reported as a perceived impairment for almost all oral impacts and was the strongest predictor of C-OIDP. Low father income was negatively associated with C-OIDP (odds ratio (OR) = 0.24, 95% confidence interval (CI) = 0.10-0.62). Females had significantly higher odds of reporting C-OIDP than males. Conclusions: In this convenience sample, a high percentage of children aged 9-12 years old reported C-OIDP, which was linked to oral impairment and socio-demographic factors. Further studies, however, are required to explore the clinical, behavioral, and sociodemographic factors in relationship to C-OIDP among Saudi children in a representative sample.

Exploring correlations between neuropsychological measures and domain-specific consistency in associations with n-3 LCPUFA status in 8-9 year-old boys and girls.

Long-chain n-3 polyunsaturated fatty acids (n-3 LCPUFA) have in some studies been associated with cognitive and socioemotional outcomes in children, but results are inconsistent possibly due to the use of different tests and potential gender-specific effects. The objective of this cross-sectional study was to explore overall patterns in neuropsychological scores as well as correlations between scores within specific domains, and to examine potential gender differences and consistency in associations with n-3 LCPUFA status. In 199 Danish 8-9 year-old children, we performed a large battery of tests and questionnaires on attention, processing speed, executive functions, memory, and socioemotional traits, and measured erythrocyte fatty acid composition. Principal component analyses (PCA) showed that most of the variation in both cognitive performance and socioemotional traits was explained by overall performance, followed by speed-accuracy trade off and externalizing vs. internalizing problems, respectively. Boys had higher speed, lower attention and higher externalizing problem scores than girls. Measures of performance within both processing speed and attention domains correlated moderately, whereas no correlations were found for measures of executive functions apart from some weak correlations for impulsivity. Parent-rated scores for both externalizing and internalizing problems correlated strongly, whereas correlations with child-rated scores were weak. Scores within specific domains did not consistently associate with n-3 LCPUFA, except for processing speed measures which all pointed to faster processing with increased n-3 LCPUFA status. Gender differences in the associations were observed for attention and impulsivity. Child- but not parent-rated internalizing and social problems tended to associate directly with n-3 LCPUFA, supported by increased internalizing problems measured by the PCA component. In conclusion, measures of speed and attention seem to represent these domains in general, whereas single measures of more complex cognitive functions should be interpreted with caution. One approach could be to use multiple tests and create multivariate scores to guide interpretations. Furthermore, the results indicate a need to consider both parent- and child-rated socioemotional scores and gender differences in neuropsychological functions e.g. in investigations of n-3 LCPUFA effects.

Quality of life of children with poor school performance: association with hearing abilities and behavioral issues.

The aim of the present study was to investigate the quality of life of children with poor school performance and its association with behavioral aspects and hearing abilities. METHODS: This cross-sectional observational study, developed in a town in the state of Minas Gerais, Brazil, investigated a random sample of public school children, aged 7-12 years old, who performed poorly in school and received specialized educational assistance. The study comprised two stages: 1) collection of data from parents on their children's health, educational, and socioeconomic profile, and from the Strengths and Difficulties Questionnaire; 2) administration of a quality of life evaluation scale to the schoolchildren. For the assessment of auditory function, transient otoacoustic emissions were used and auditory processing was tested. The following tests were used: verbal sequential memory, nonverbal sequential memory, sound localization, dichotic digits, duration pattern test (flute) and random gap detection. The collected data were analyzed using Excel and STATA 11.0 software. Quality of life was considered the response variable. The explanatory variables were grouped for univariate and multivariate logistic regression analysis with the level of significance set at 5%. RESULTS: A statistically significant association was found between impaired quality of life, altered pro-social behavior, and the absence of parental complaints about the children's written language development. CONCLUSIONS: Quality of life is impaired in children with poor school performance. The lack of parental complaints about written language and changes in social behavior increased the likelihood of a child having a poor quality of life.

Emotion regulation moderates the association between parent and child hair cortisol concentrations.

Successful emotion regulation facilitates children's coping with everyday stress. It develops rapidly in the early preschool period. However, no work has been done to investigate the potential buffering role of emotion regulation from cumulative physiological effects of stress. In this study, we examined hair cortisol concentration (HCC), an early marker of chronic physiological stress, socioeconomic status (SES), parental sensitivity, and emotion regulation and reactivity in a sample of 3.5-year-old children (N = 86). Emotion regulation and emotional reactivity were independent of child HCC. However, emotion regulation moderated the relationship between parent and child HCC. For children with better emotion regulation, there was no association between parent and child HCC, suggesting that emotion regulation skills buffered the transgenerational effects of chronic physiological stress. Emotional reactivity moderated the relationship between SES and child HCC, and attenuated the association between parental sensitivity and child HCC. Taken together, these findings demonstrate that children who were less emotionally reactive were less susceptible to their environments. Results provide support that child emotion regulation and emotional reactivity can reduce or strengthen the relationship between established risk factors and levels of chronic physiological stress in early childhood.

Association of School Physical Activity Policies With Student Physical Activity Behavior.

Background: Few studies have examined school physical activity policies to assess dose-response on student outcomes. The purpose of this study was to evaluate the association between health-promoting physical activity policies in elementary schools and physical activity behavior. Methods: In this cross-sectional study, physical activity was assessed using self-report measures in fourth-grade students in Texas (N = 1958, x = 9.66 y) from the School Physical Activity and Nutrition (SPAN) survey. School policies were assessed using the number of health-promoting policies in place taken from the SPAN School Health Survey with principals and their proxies. Multiple linear regressions adjusted for student- and school-level confounders and school clustering were performed. Results: School physical activity policies were significantly associated with student-level physical activity behavior (P < .05), even after controlling for the student- and school-level confounding variables. The interactions between physical activity policy-by-economic disadvantage (P < .01) and between physical activity policy-by-geographic strata (P < .01) were both significant, with stronger direct effects of policies on student physical activity for economically disadvantaged schools and major urban schools. Conclusion: Results from this study provide evidence for the importance of school-based health policies and practices in potentially reducing health disparities, especially in low-income and urban schools.

Quality of life of children with poor school performance: association with hearing abilities and behavioral issues / Qualidade de vida de crianças com mau desempenho escolar: associação com as habilidades auditivas e aspectos comportamentais

Resultados: Foi encontrada associação estatística entre qualidade de vida prejudicada, comportamento pró-social alterado e ausência de queixa parental de linguagem escrita. Conclusão: A qualidade de vida está comprometida nas crianças com mau desempenho escolar. A ausência de queixa sobre o desenvolvimento da linguagem escrita e comportamento pró-social alterado aumentaram a chance de a criança apresentar qualidade de vida prejudicada.

Cultural differences in the development of a preference for scarce objects.

Adults value scarce objects, such as rare precious stones and limited edition items. This valuation may derive from an understanding of market forces and sociological considerations, but it may also be related to more basic cognitive and motivational processes. The present studies addressed these possibilities by investigating the development and cross-cultural prevalence of a preference for scarce objects. Children (N = 366) from Israel and Taiwan, ranging from 4 to 11 years of age, were given a choice between a scarce and an abundant reward. We found that whereas a preference for the scarce appeared among Israelis by age 7, it never appeared among the Taiwanese. These findings indicate that a scarcity preference emerges already at age 7, but only among children living in a culture that emphasizes self-individuality. These findings are discussed in light of cultural accounts of the development of self-motivations. (PsycINFO Database Record (c) 2018 APA, all rights reserved).
