RESUMO

El objetivo fue examinar, desde una aproximación multi-informante, las medidas del Síndrome de Desconexión Cognitiva (SDC) de padres/madres e hijos/as y su relación con síntomas internalizantes y externalizantes. 279 niños/as (9-13 años), y sus padres/madres completaron las evaluaciones sobre SDC, la inatención del trastorno por déficit de atención e hiperactividad (TDAH) y otras medidas internalizadas y externalizadas. Los ítems de las tres medidas de SDC convergieron razonablemente bien en el factor SDC. Se aportaron pruebas discriminantes de la validez de las relaciones entre las puntuaciones de las pruebas y las medidas de los tres constructos diferentes (SDC, soledad y preferencia por la soledad). La asociación más estrecha estuvo entre la evaluación parental de las medidas de SDC con ansiedad y depresión, y entre inatención con hiperactividad/impulsividad y trastorno negativista desafiante. Se observó capacidad predictiva de la medida de SDC sobre la soledad y preferencia por estar solo autoinformadas. Se encontró una posible asociación entre la medida del SDC evaluado por padres/madres y sexo y edad de los niños. En conclusión, los datos apoyan la inclusión de medidas autoinformadas en la evaluación del SDC. Las medidas del SDC en niños se vinculan con medidas internalizantes y, la inatención con las externalizantes.(AU)

RESUMO

Objective: To investigate the association between gestational blood pressure and neurodevelopment in 2-year-old children. Methods: Based on the"Wuhan Healthy Baby Birth Cohort", 3 754 mother-infant pairs were enrolled in this study. Based on multiple blood pressure measurements during pregnancy, the mean, cumulative, and variability of blood pressure throughout the entire pregnancy and each trimester were calculated. Blood pressure variability was evaluated using standard deviation (SD), coefficient of variability (CV), and variability independent of mean (VIM). Follow-up testing of neurodevelopment in infants and young children at the age of two was conducted to obtain the Mental Development Index (MDI) and the Psychomotor Development Index (PDI). The multivariate linear regression and generalized estimation equation were used to analyze the association between gestational blood pressure data and neurodevelopmental index. Results: The age of 3 754 pregnant women was (29.1±3.6) years, with a pre-pregnancy BMI of (20.9±2.7) kg/m² and a gestational age of (39.3±1.2) weeks. The birth weight of 3 754 children was (3 330.9±397.7) grams, and the birth length was (50.3±1.6) centimeters. The results of the multivariate linear regression analysis showed that after adjusting for relevant confounding factors, the mean blood pressure, cumulative blood pressure, standard deviation of blood pressure, coefficient of variation of blood pressure, independent blood pressure variability of systolic blood pressure, diastolic blood pressure, and pulse pressure throughout pregnancy were negatively associated with the MDI and PDI scores of 2-year-old children. The analysis results of the generalized estimation equation showed that after adjusting for relevant confounding factors, the average systolic blood pressure in the first, second, and third trimesters was negatively associated with MDI/PDI. The negative association between cumulative blood pressure and MDI/PDI was only found in the first trimester. The negative association between blood pressure variation during pregnancy and MDI/PDI was mainly concentrated in the second and third trimesters. Conclusion: There is a negative association between gestational blood pressure and the neurodevelopmental index of 2-year-old children.

RESUMO

OBJECTIVES: To evaluate the clinical efficacy of short-peptide exclusive enteral nutrition (EEN) therapy in inducing remission during active Crohn's disease (CD) in children, as well as changes in physical growth and nutritional indicators before and after treatment. METHODS: A prospective study included 43 children with active CD who were admitted to the Department of Gastroenterology, Children's Hospital of Nanjing Medical University from January 2017 to January 2024. The participants were randomly divided into a medication treatment group (13 children) and a short-peptide + medication treatment group (30 children). The changes in the Pediatric Crohn's Disease Activity Index (PCDAI) scores, physical growth, and nutritional indicators before and after treatment were analyzed in both groups. RESULTS: The PCDAI scores in the short-peptide + medication treatment group were lower than those in the medication treatment group after treatment (P<0.05). The Z-scores for weight-for-age, body mass index, and albumin levels were higher in the short-peptide + medication treatment group compared to the medication treatment group (P<0.05). In the patients with moderate to severe CD, total protein levels in the short-peptide + medication treatment group were significantly higher than those in the medication treatment group (P<0.05). CONCLUSIONS: Short-peptide EEN therapy can induce clinical remission in children with active CD and promote their physical growth while improving their nutritional status.

RESUMO

Negation-triggered inferences are universal across human languages. Hearing "This is not X" should logically lead to the inference that all elements other than X constitute possible alternatives. However, not all logically possible alternatives are equally accessible in the real world. To qualify as a plausible alternative, it must share with the negated element as many similarities as possible, and the most plausible one is often from the same taxonomic category as the negated element. The current article reports on two experiments that investigated the development of preschool children's ability to infer plausible alternatives triggered by negation. Experiment 1 showed that in a context where children were required to determine the most plausible alternative to the negated element, the 4- and 5-year-olds, but not the 3-year-olds, exhibited a robust preference for the taxonomic associates. Experiment 2 further demonstrated that the 3-, 4- and 5-year-olds considered all the complement set members as equally possible alternatives in a context where they were not explicitly required to evaluate the plausibility of different candidates. Taken together, our findings reveal interesting developmental continuity in preschool children's ability to make inferences about plausible alternatives triggered by negation. We discuss the potential semantic and pragmatic factors that contribute to children's emerging awareness of typical alternatives triggered by negative expressions.

RESUMO

Insecure-attached adults are more likely to lie. However, it is unknown whether infant-parent attachment quality relates to lie-telling in early childhood. As in adults, lie-telling in early childhood might be related to attachment insecurity. However, a competing hypothesis might be plausible; lie-telling might be related to attachment security given that lie-telling in early childhood is considered an advancement in social-cognitive development. The current study is the first to investigate the link between insecure/secure and disorganized/non-disorganized attachment and lie-telling behavior in early childhood. Because lie-telling is studied in the context of cheating behavior, the association between cheating and attachment is additionally explored. A total of 560 Dutch children (287 girls) from a longitudinal cohort study (Generation R) were included in the analyses. Attachment quality with primary caregiver (secure/insecure and disorganized/non-disorganized attachment) was assessed at 14 months of age in the Strange Situation Procedure, and cheating and lie-telling were observed in games administered at 4 years of age. The results demonstrated no relationship of attachment (in)security and (dis)organization with cheating and lie-telling. Results are interpreted in light of evidence that lie-telling in early childhood is part of normative development. Limitations are discussed, including the time lag between assessments, the fact that lie-telling was measured toward a researcher instead of a caregiver, and the conceptualization of attachment in infancy versus adulthood. Attachment quality does not affect early normative lie-telling, but how and when it may affect later lying in children remains to be explored.

RESUMO

School-aged children have consistently shown a surprising developmental lag when attempting to innovate solutions to tool use tasks, despite being capable of learning to solve these problems from a demonstrator. We suggest that this "innovation gap" arises from tool tasks with more complex spatial relations. Following Fragaszy and Mangalam's new tooling theory, we predicted that innovating a new "sticker slide" task should be more challenging when two tools need to be used at the same time (concurrently) rather than one at a time (sequentially), despite the similarity of the other task elements. In line with previous work, both versions of the task were challenging for all ages of children (4-9 years) that we tested. However, the youngest group showed particularly extreme difficulties, which was marked by not a single child innovating the concurrent version. Although success significantly increased with age, even the oldest group failed to reach 50% success on the concurrent version of the task, whereas the majority of the two older groups could solve the sequential version. Thus, in this first study of concurrent tool use in children, we found support for the prediction that increasing the complexity of spatial relations in tooling exacerbates the innovation gap.

RESUMO

Neurosyphilis is an infection of the central nervous system caused by Treponema pallidum and may be symptomatic or asymptomatic in children with congenital syphilis. This study aims to describe the cortical activation pattern of a four-month-old infant with neurosyphilis using functional near-infrared spectroscopy (fNIRS). Born at term weighing 3,475 kg, she presented a Venereal Disease Research Laboratory (VDRL) test of 1:32 and changes in the cerebrospinal fluid test. She underwent treatment with crystalline penicillin for 10 days before discharge from the hospital. In the audiological evaluation, she presented normal tympanometry, otoacoustic emissions evoked by transient stimulus, brainstem auditory evoked potential with click stimulus at 80 and 30 dB nHL bilaterally. The Bayley III Scale was applied to assess language, cognition and motor development, showing delays in expressive language and broad motor skills. In the fNIRS acquisition, data were collected through 20 channels divided between the cerebral hemispheres. The /ba/ and /da/ stimuli were presented at 40 dB HL with the Psychopy software through a headphone. Data analysis used the MNE and MNE-NIRS toolboxes in the Spyder environment. The average by channel, ROI, and condition was exported for analysis. A similar theta coefficient was observed between the conditions and channels evaluated in both cerebral hemispheres, with a greater amplitude of oxyhemoglobin (HbO) being observed in the anterior position when compared to the posterior region of the temporal lobe. Therefore, this case report highlights the need to monitor the child development of babies with neurosyphilis.


A neurossífilis é uma infecção do sistema nervoso central causada pelo Treponema pallidum, podendo ser sintomática ou assintomática nas crianças com sífilis congênita. Este estudo visa descrever o padrão de ativação cortical de uma lactente de quatro meses com neurossífilis utilizando o funcional near-infrared spectroscopy (fNIRS). Nascida a termo com 3.475 Kg, apresentou teste Venereal Disease Research Laboratory (VDRL) de 1:32 e alteração no exame de líquor cefalorraquidiano. Realizou tratamento com penicilina cristalina por 10 dias antes da alta hospitalar. Na avaliação audiológica apresentou normalidade na timpanometria, emissões otoacústicas evocadas por estímulo transiente, potencial evocado auditivo de tronco encefálico com estímulo clique a 80 e 30 dB nNA bilateralmente. Foi aplicada a Escala Bayley III para a avaliação do desenvolvimento de linguagem, cognição e motor, apresentando atrasos na linguagem expressiva e no motor amplo. Na aquisição do fNIRS os dados foram coletados por 20 canais divididos entre os hemisférios cerebrais. Os estímulos /ba/ e /da/ foram apresentados a 40 dB NA com o auxílio do programa Psychopy por um fone de ouvido. A análise dos dados utilizou as toolboxes MNE e MNE-NIRS no ambiente Spyder. A média por canal, ROI e condição foi exportada para análise. Observou-se um coeficiente theta similar entre as condições e canais avaliados de ambos os hemisférios cerebrais, sendo observado maior amplitude da oxihemoglobina (HbO) na posição anterior quando comparados a região posterior do lobo temporal. Desta forma, este relato de caso evidencia a necessidade de monitoramento do desenvolvimento infantil de lactentes com neurossífilis.

RESUMO

BACKGROUND: Poor early childhood development (ECD) is a major global health concern that is associated with various adverse outcomes over the lifecourse. Parenting interventions especially during the earliest years of life can benefit ECD. However, there is limited evidence from Kenya about the effectiveness of parenting interventions for improving ECD outcomes especially across rural disadvantaged communities. This paper describes the study protocol for an impact and implementation evaluation of a community-based group parenting program that aims to improve ECD in rural Kenya. METHODS: We will conduct a cluster-randomized controlled trial to determine the effectiveness of a parenting program for caregivers of young children in Homabay and Busia counties in Western Kenya. Sixty-four village clusters will be randomly assigned to either the parenting intervention arm or the waitlist control arm with stratification by county. In each village, 10 primary caregivers with a child aged 0-24 months will be enrolled. The parenting program will be delivered through existing peer groups within communities whereby caregivers will receive counseling and psychosocial support to enhance their parenting skills and wellbeing to in turn promote ECD. The intervention curriculum comprises 21 sessions targeting various nurturing care messages, including early learning, responsive caregiving, child nutrition, health, protection, and caregiver mental health. Group sessions are facilitated by a trained volunteer biweekly for a total of 11 months. The primary trial outcome is an overall measure of ECD using the Global Scales of Early Development long form version. Secondary outcomes include various caregiver outcomes (e.g., parenting practices, mental health) and other child outcomes (e.g., socioemotional development, dietary diversity). All outcomes will be assessed at baseline and endline. We will also conduct a qualitative implementation evaluation at endline and interview various stakeholders to assess program fidelity, quality, and sustainability. DISCUSSION: This trial will evaluate the effectiveness of a parenting intervention on ECD and caregiving outcomes and assess program implementation quality as delivered through existing community-based peer groups. This study will provide rigorous evidence that can be used to inform scale-up of this program model that leverages existing community social networks and resources for improving caregivers' parenting skills and promoting ECD in rural Kenya and other similar settings across LMICs. TRIAL REGISTRATION: ClinicalTrials.gov #NCT06165315. Registered on December 11, 2023.

RESUMO

Throughout infancy, changes in growth and development are observed, including changes in nutritional requirements; at approximately 6 months of age, when complementary feeding begins, breastmilk and/or formula are no longer the sole source of energy and nutrients. Little is known about the impact of complementary feeding (CF) approaches used during this time on infant nutrition and growth. Baby-led weaning (BLW) has continued to gain popularity over the last two decades, emphasizing the importance of examining the adequacy of different CF methods. This narrative review of 19 studies from January 2010 to April 2024 aims to discuss the differences between BLW and conventional weaning (CW). The definition of BLW varied across studies, and no standard definition has been established. Though no differences in energy were reported, macronutrient and micronutrient intakes were variable between approaches, including for micronutrients such as iron and zinc. Of the few studies with growth data, results comparing BLW and CW were conflicting. Differences were seen in the demographics of parents who chose to follow BLW and breastfeeding prevalence and duration prior to complementary feeding. Additional research is needed to understand the impacts of BLW and CW on nutrient intakes and growth to inform recommendations for infant complementary feeding approaches.

RESUMO

INTRODUCTION: Rapid growth in early childhood has been identified as a possible risk factor for long-term adiposity. However, there is a lack of studies quantifying this phenomenon only in healthy, full-term infants with appropriate birth weight for gestational age. This systematic review and meta-analysis aimed to investigate the association of rapid growth in full-term children up to 2 years of age with adiposity up to 18 years of age. METHODOLOGY: A systematic review of the literature was conducted in PubMed, EMBASE, and Web of Science. RESULTS: 14 studies were included. We were unable to find strong evidence that rapid growth in early childhood is a risk factor for long-term adiposity. Rapid growth in early childhood was associated with taller heights (standardized mean difference: 0.51 (CI: 0.25-0.77)) and higher body mass index (standardized mean difference: 0.50 (CI: 0.25-0.76)) and a higher risk of overweight under 18 years. CONCLUSION: Rapid growth in early childhood in term infants with appropriate birth weight is associated with higher growth, body mass index, and risk of being overweight up to age 18, but further work is needed to identify the associations between early rapid growth and obesity later in adulthood.

RESUMO

BACKGROUND: Human milk oligosaccharides (HMOs), which are unique bioactive components in human milk, are increasingly recognized for their multifaceted roles in infant health. A deeper understanding of the nexus between HMOs and the gut-brain axis can revolutionize neonatal nutrition and neurodevelopmental strategies. METHODS: We performed a narrative review using PubMed, Embase, and Google Scholar to source relevant articles. The focus was on studies detailing the influence of HMOs on the gut and brain systems, especially in neonates. Articles were subsequently synthesized based on their exploration into the effects and mechanisms of HMOs on these interconnected systems. RESULTS: HMOs significantly influence the neonatal gut-brain axis. Specific concentrations of HMO, measured 1 and 6 months after birth, would seem to agree with this hypothesis. HMOs are shown to influence gut microbiota composition and enhance neurotransmitter production, which are crucial for brain development. For instance, 2'-fucosyllactose has been demonstrated to support cognitive development by fostering beneficial gut bacteria that produce essential short-chain fatty acids. CONCLUSIONS: HMOs serve as crucial modulators of the neonatal gut-brain axis, underscoring their importance in infant nutrition and neurodevelopment. Their dual role in shaping the infant gut while influencing brain function presents them as potential game-changers in neonatal health strategies.

RESUMO

Children's episodic future-thinking is typically assessed using experimental tasks that measure whether children select an item with future utility. Although these tasks-inspired by Tulving's seminal 'spoon test' (Tulving E. 2005 Episodic memory and autonoesis: uniquely human? In The missing link in cognition: origins of self-reflective consciousness [eds HS Terrace, J Metcalfe], pp. 3-56. Oxford, UK: Oxford University Press. [doi:10.1093/acprof:oso/9780195161564.001.0001])-are passed around age 4, they tell us little about the functional significance of children's episodic future-thinking in their day-to-day lives. We highlight how a naturalistic approach can shed light on this issue, and present a small study where we recruited mothers to report on their children's (N = 12, 3- and 4-year-olds and 6- and 7-year-olds) future-thinking over a 7-day period. We used a thematic analysis to understand why children express future thoughts and derived the following themes: (1) expressing future desires and/or intentions, (2) future-oriented information-seeking, (3) connecting present actions with future outcomes, and (4) predicting future mental/physiological states. We compare these themes with recent accounts of the functional significance of future-thinking in adults and conclude that children largely express their future-thinking verbally to request information or support from their parent-likely because they do not yet possess enough control/autonomy to independently act for their own future. Our findings both complement and extend an experimental approach and further elucidate the functional significance of mental time travel in children. This article is part of the theme issue 'Elements of episodic memory: lessons from 40 years of research'.

RESUMO

INTRODUCTION: Preterm birth (PTB) is strongly associated with encephalopathy of prematurity (EoP) and neurocognitive impairment. The biological axes linking PTB with atypical brain development are uncertain. We aim to elucidate the roles of neuroendocrine stress activation and immune dysregulation in linking PTB with EoP. METHODS AND ANALYSIS: PRENCOG (PREterm birth as a determinant of Neurodevelopment and COGnition in children: mechanisms and causal evidence) is an exposure-based cohort study at the University of Edinburgh. Three hundred mother-infant dyads comprising 200 preterm births (gestational age, GA <32 weeks, exposed) and 100 term births (GA >37 weeks, non-exposed), will be recruited between January 2023 and December 2027. We will collect parental and infant medical, demographic, socioeconomic characteristics and biological data which include placental tissue, umbilical cord blood, maternal and infant hair, infant saliva, infant dried blood spots, faecal material, and structural and diffusion MRI. Infant biosamples will be collected between birth and 44 weeks GA.EoP will be characterised by MRI using morphometric similarity networks (MSNs), hierarchical complexity (HC) and magnetisation transfer saturation imaging (MTsat). We will conduct: first, multivariable regressions and statistical association assessments to test how PTB-associated risk factors (PTB-RFs) relate to MSNs, HC and or MTsat; second, structural equation modelling to investigate neuroendocrine stress activation and immune dysregulation as mediators of PTB-RFs on features of EoP. PTB-RF selection will be informed by the variables that predict real-world educational outcomes, ascertained by linking the UK National Neonatal Research Database with the National Pupil Database. ETHICS AND DISSEMINATION: A favourable ethical opinion has been given by the South East Scotland Research Ethics Committee 02 (23/SS/0067) and NHS Lothian Research and Development (2023/0150). Results will be reported to the Medical Research Council, in scientific media, via stakeholder partners and on a website in accessible language (https://www.ed.ac.uk/centre-reproductive-health/prencog).

RESUMO

Research and theory suggest an important role of neuroendocrine function in emotional development, particularly under conditions of elevated stress. We provide empirical data to clarify associations between alpha-amylase (AA) and cortisol as well as test the differential linkages among AA, cortisol, and symptoms of anxiety, depression, and posttraumatic stress in children. Children recruited from a low-income elevated violence community (n = 100; mean age = 10, SD = 0.64; 79% Latino; 67% received free or reduced lunch) were assessed on diurnal levels of AA and cortisol along with assessments of anxiety, depression, and posttraumatic stress symptoms (PTSS). Elevated anxiety symptoms were associated with steeper linear slopes of AA with higher levels of AA in the morning but lower levels of AA in the evening. Depression was associated with differential cubic trajectories of AA when PTSSs were included in the model. Anxiety also predicted differential cubic diurnal trends in cortisol, such that greater anxiety symptoms were associated with relatively higher levels of cortisol in the evening. Again, depression symptoms when PTSS were included predicted diurnal cubic trends with elevated depression associated with lower awakening and midday cortisol that reversed to higher evening cortisol compared to youth with fewer self-reported depression symptoms.

RESUMO

BACKGROUND: Research into the impact of social relationships on childhood and adolescent health and wellbeing has been largely limited to children's relationships with other humans, while studies into the impact of pet ownership are sparse and have generally not adjusted for potential confounders. This study aimed to investigate the association between pet ownership and a range of developmental outcomes in childhood and adolescence. METHODS: Data were self-reports and direct assessments of approx. 14,000 children from the Avon Longitudinal Study of Parents and Children (ALSPAC). Multivariable regression models adjusting for confounding factors examined associations between developmental outcome measures (emotional health, behavioural development, cognitive development, language development, educational attainment) and concurrent pet ownership, including species, and also longitudinal pet ownership history and pet-interaction where possible. Analyses model numbers using multiple imputation varied from n = 393-8963. RESULTS: In cross-sectional analyses, owning a dog (b = 0.24, [0.06-0.41], p = .004) and owning other/miscellaneous pets (b = 0.18, [0.03-0.33], p = .021) at age 3 were associated with higher prosocial behaviour score. Owning a pet was associated with a higher non-verbal communication score at age 2 (cross-sectional, b = 0.18, [0.04-0.32], p = .014), and a higher language development score at age 5 (cross-sectional, b = 1.01, [0.18-1.83], p = .017). However, pet ownership was associated with lower educational attainment across a number of academic subjects and timepoints, in both cross-sectional and longitudinal analyses. It was also cross-sectionally linked to hyperactivity at age 3 and conduct problems at age 3 and 11. Furthermore, at age 8, cross-sectional analysis showed that children who owned any pets (OR [95% CI]: 0.85 [0.73-0.98], p= ·026) or cats (0.83, [0.73-0.95], p= ·006) had lower odds of high self-esteem (scholastic competence). CONCLUSIONS: Using a large, well-designed longitudinal study and adjusting for key confounders, we found little evidence of cross-sectional or longitudinal associations between pet ownership and emotional health or cognitive outcomes in children. There may, however, be some cross-sectional and longitudinal association with poorer educational attainment and a positive impact on social interactions as seen through associations with enhanced language development and prosocial behaviour. This study demonstrates the importance of adjustment for confounding variables and suggests that, contrary to popular belief, positive impacts of pet ownership on childhood development may be mainly limited to social behaviour and language development.

RESUMO

BACKGROUND: Unresolved/disorganized (U/d) attachment states of mind are associated with poor outcomes across numerous domains of functioning. However, the validity of existing self-report instruments measuring this construct remains questionable. OBJECTIVES: The aim of the current study was to validate the DRS-8, an alternative version of the Disorganized Response Scale (DRS), by assessing its construct validity, internal consistency, and criterion validity with the U/d attachment scales on the Adult Attachment Interview (AAI). PARTICIPANTS AND SETTING: Date were collected from 222 expectant parents (78 % women) at T1 and from 67 of them at 12 months postpartum (T2). METHODS: Participants completed the DRS-8 and questionnaires assessing childhood trauma, romantic attachment, and psychological symptoms during pregnancy (T1). Seventy-four of them participated in the AAI at T1. At T2, parents completed a questionnaire assessing their infants' social-emotional development. RESULTS: The DRS-8 has two highly correlated dimensions, i.e., lapses in the monitoring of reasoning (four items) and discourse (four items). A confirmatory factor analysis supported a bifactor structure of the instrument, showing good fit indices and internal consistency (ω = 0.87). The DRS-8 was significantly correlated with U/d states of mind on the AAI, r(72) = 0.28, p = .016, and demonstrated excellent construct validity. Significant indirect effects of the DRS-8 were found in the associations between childhood trauma and psychological symptoms, and between parental trauma and infant social-emotional development. CONCLUSIONS: The DRS-8 appears to be a promising self-report measure of U/d states of mind showing criterion validity with the AAI.

RESUMO

This chapter provides the most comprehensive review of risk and resilience models for child development thus far, synthesizing these interdisciplinary frameworks for ease of use in research and practice. This review specifically focuses on process models with broader conceptualizations of risk and resilience that have effects across multiple developmental domains. Risk and resilience models alike agree that alleviating risk factors is beneficial for children's development, including risks ranging from proximal issues with households (e.g., instability) and caregivers (e.g., insecure attachment, abuse) to relatively distal influences like structural racism and socioeconomic status. Resilience models further add that children who experience risks are not inherently doomed to poorer outcomes, but can draw upon positive factors in development to combat negative effects from risk, which cannot always be avoided. Major positive factors include loving relationships, educational resources, and cultural assets. Risk and resilience are highly multidisciplinary fields that have contributed much to our understanding of human development, with ample room for continued growth. Understanding of risk and resilience processes, especially during sensitive developmental periods like early childhood, provides valuable insight for prevention and intervention research and practices. Risk and resilience models share an interest in deciphering the developmental processes that hinder and help children across domains so that kids can live their best lives, resulting in a better off society for all.

RESUMO

The last 40 years have been marked by a growing appreciation of organized afterschool activities as a developmental context, with evidence that these activities are linked to academic, social, and behavioral outcomes at least in the short term. In this chapter, we focus on research that builds on these earlier advances to extend afterschool research in two areas that are critical to the future of this field. First, we feature research that examines organized activities longitudinally from kindergarten through the end of high school, enabling us to study organized activities in relation to academic, social-emotional, behavioral, and health outcomes in both the short-run and long-run, including into adulthood. We then turn to a second advance: research focused on organized activities that serve minoritized children and adolescents. These studies identify the barriers minoritized youth often face and how activities can be designed to support their positive development, including efforts to provide culturally responsive programming. Promising directions for future research are presented in a third section.

RESUMO

Decades of research have informed about ways in which infants and young children learn through action in connection with their sensory system. However, this research has not strongly addressed the issues of cultural diversity or taken into account everyday cultural experiences of young learners across different communities. Diversifying the scholarship of early learning calls for paradigm shifts, extending beyond the analysis at the individual level to make close connections with real-world experience while placing culture front and center. On the other hand, cultural research that specifies diversity in caregiver guidance and scaffolding, while providing insights into young learners' cultural experiences, has been conducted separately from the research of action-based cross-modal learning. Taking everyday activities as contexts for learning, in this chapter, we summarize seminal work on cross-modal learning by infants and young children that connects action and perception, review empirical evidence of cultural variations in caregiver guidance for early action-based learning, and make recommendations of research approaches for advancing the scientific understanding about cultural ways of learning across diverse communities.

RESUMO

According to the Relational Developmental Systems perspective, the development of individual differences in spatial thinking (e.g., mental rotation, spatial reorientation, and spatial language) are attributed to various psychological (e.g., children's cognitive strategies), biological (e.g., structure and function of hippocampus), and cultural systems (e.g., caregiver spatial language input). Yet, measuring the development of individual differences in spatial thinking in young children, as well as the psychological, biological, and cultural systems that influence the development of these abilities, presents unique challenges. The current paper outlines ways to harness available technology including eye-tracking, eye-blink conditioning, MRI, Zoom, and LENA technology, to study the development of individual differences in young children's spatial thinking. The technologies discussed offer ways to examine children's spatial thinking development from different levels of analyses (i.e., psychological, biological, cultural), thereby allowing us to advance the study of developmental theory. We conclude with a discussion of the use of artificial intelligence.
