The neural correlates of working memory training in typically developing children     

Jonathan S. Jones  Anna-Lynne R. Adlam  Abdelmalek Benattayallah  Fraser N. Milton 《Child development》2022,93(3):815-830

Working memory training improves children's cognitive performance on untrained tasks; however, little is known about the underlying neural mechanisms. This was investigated in 32 typically developing children aged 10–14 years (19 girls and 13 boys) using a randomized controlled design and multi-modal magnetic resonance imaging (Devon, UK; 2015–2016). Training improved working memory performance and increased intrinsic functional connectivity between the bilateral intraparietal sulci. Furthermore, improvements in working memory were associated with greater recruitment of the left middle frontal gyrus on a complex span task. Repeated engagement of fronto-parietal regions during training may increase their activity and functional connectivity over time, affording greater working memory performance. The plausibility of generalizable cognitive benefits from a neurobiological perspective and implications for neurodevelopmental theory are discussed.  相似文献   

Child Effects on Parental Negativity: The Role of Heritable and Prenatal Factors     

Chang Liu  Linying Ji  Sy-Miin Chow  Boyoung Kang  Leslie D. Leve  Daniel S. Shaw  Jody M. Ganiban  Misaki N. Natsuaki  David Reiss  Jenae M. Neiderhiser 《Child development》2020,91(5):e1064-e1081

This study examined two possible mechanisms, evocative gene–environment correlation and prenatal factors, in accounting for child effects on parental negativity. Participants included 561 children adopted at birth, and their adoptive parents and birth parents within a prospective longitudinal adoption study. Findings indicated child effects on parental negativity, such that toddlers’ negative reactivity at 18 months was positively associated with adoptive parents’ over-reactive and hostile parenting at 27 months. Furthermore, we found that child effects on parental negativity were partially due to heritable (e.g., birth mother [BM] internalizing problems and substance use) and prenatal factors (e.g., BM illicit drug use during pregnancy) that influence children’s negative reactivity at 18 months. This study provides critical evidence for “child on parent” effects.  相似文献   

Adolescent academic achievement: A model of social support and grit     

Kelly N. Clark  Nicole B. Dorio  Morgan A. Eldridge  Christine K. Malecki  Michelle K. Demaray 《Psychology in the schools》2020,57(2):204-221

Grit has been defined as passionate perseverance toward long-term challenging goals and it is associated with various positive outcomes for youth, including academic achievement. However, less is known about these associations for the two facets of grit (i.e., perseverance of effort, consistency of interest) and few studies have examined the link between grit and perceived social support. The present study examined the group-level demographic differences (i.e., gender, grade, socioeconomic status, and special education status) of grit in a high school sample (N = 1,077). In addition, direct associations between grit and perceived social support from multiple sources (i.e., teacher, classmate, parent) were examined, as well as a potential enhancing effect of social support as a moderator of the relation between grit and academic achievement. Results indicated positive associations among grit and its facets with social support from parents and classmates. Furthermore, the positive relation between grit and achievement was stronger for students reporting high social support from teachers, but not other sources (i.e., classmates, parents). Practical and theoretical implications for promoting student success are discussed.  相似文献   

Disaggregating the Creationist Challenge to Liberal Neutrality     

CRISTÓBAL BELLOLIO 《Journal of Philosophy of Education》2020,54(1):62-80

In the US and elsewhere, creationist groups have challenged the mandatory science curriculum because it introduces the theory of evolution as the true story of biodiversity. This paper disaggregates this challenge in two distinctive levels. On the substantive level, creationists claim that Darwinian evolution is not value-neutral, as most scientists portray it, but it works as a philosophically-loaded theory that amounts to naturalism, which is a comprehensive doctrine that undermines traditional theism. Creationists then contend that its exclusive teaching violates the liberal promise of religious neutrality. To restore metaphysical fairness, they propose to include non-naturalistic theories into the official curriculum as a way of balance. On the epistemic level, creationists criticise liberal institutions—from courts of justice to educational boards and executive officials—that demarcate science in a way in which supernatural hypotheses can never compete for the best factual explanation. Under the guise of a purely methodological naturalism, they argue, liberals are opting for a cognitive filter that is biased against the belief that God intervenes in cosmic history. To restore epistemological fairness, they propose that theories that suggest supernatural agency should be rehabilitated and eventually included in the science curriculum. In these two distinct levels, the creationist claim is advanced as a logical implication of political liberalism's purported commitment to religious impartiality.  相似文献   

Gender-Typed and Gender-Segregated Play Among Tanzanian Hadza and Congolese BaYaka Hunter-Gatherer Children and Adolescents     

Sheina Lew-Levy  Adam H. Boyette  Alyssa N. Crittenden  Barry S. Hewlett  Michael E. Lamb 《Child development》2020,91(4):1284-1301

Few data exist on gender-typed and gender-segregated play in hunter-gatherer societies, despite their unique demographic and cultural features which may influence children’s gendered play. Using naturalistic observations of Hadza (N = 46, 41% female) and BaYaka (N = 65, 48% female) hunter-gatherer 3- to 18-year-olds from Tanzania and the Republic of Congo, we showed that access to playmates was negatively associated with playing in mixed-gender groups. Young boys did not engage in more rough-and-tumble play than girls, but adolescent boys participated in this type of play more than adolescent girls. Children were also more likely to participate in work-themed play which conformed to gender norms within their society. Findings are discussed within the context of gendered division of labor, child autonomy, and demography.  相似文献   

Hot and Cool Self-Regulation,Academic Competence,and Maladjustment: Mediating and Differential Relations     

Agathe Backer-Grøndahl  Ane Nærde  Thormod Idsoe 《Child development》2019,90(6):2171-2188

This study examined differential and mediating relations between hot and cool self-regulation (M_age = 48.2 months; N = 1,155, 48% girls), first-grade (M_age = 77.5 months) maladjustment (externalizing [EXT] and internalizing [INT] behavior), and first- and second-grade (M_age = 89.5 months) academic competence (AC). Using teacher reported EXT, INT, and AC, partial support for the differential perspective was found in that only hot self-regulation was significantly related to EXT, whereas both hot and cool self-regulation was significantly related to AC. Moreover, hot self-regulation indirectly predicted second-grade AC through first-grade EXT, lending some support for the mediating perspective also. The findings contribute to an understanding of how self-regulation is related to academic and behavioral school adjustment.  相似文献   

The Socio-Cultural Image of Childhood (Based on an Analysis of Soviet and Russian Feature Films about Children)     

K.N. Polivanova  M.A. Shakarova 《Russian Education & Society》2018,60(4):348-369

The current state of childhood research is grounded in classical psychological theories, and Russian psychology is tied to cultural and historical theory in particular. These theories were invented to generalize and make sense of the realities of childhood as they existed at the time when these theories were created. Rapid social changes, especially during recent decades, have led to the emergence of a wide range of sources that bear witness to how the day-to-day life of childhood has changed. The understanding of childhood has continued to transform from one era to another. A metaphor was even coined to describe it, and at some point there was even a specific metaphor coined, “the disappearance of childhood.” This article seeks to explore how the image of childhood has changed in relation to the image of adulthood. As material for analysis, we chose Soviet and Russian movies from the 1940s to 2000s. The study is based on the assumption that a sequential analysis based on Yuri Lotman’s theory of the structure of the text demonstrates how the image of childhood changes over time. If in the 1940s and 1950s the child was presented as immature and not quite grown up, the adult was portrayed as the embodiment of the ideal form of the individual, and the main conflict was structured around childish immaturity, then gradually over the decades more and more main characters who were children and adults were portrayed as different kinds of individuals, and the child (or teenager) sometimes came to embody obviously negative features. The child–adult dichotomy itself lost its significance.  相似文献   

Responses to oral glucose challenge differ by physical activity volume and intensity: A pilot study     

Trevor N. Simper  Cecile Morris  Anthony Lynn  Ciara O'Hagan  Karen Kilner 《运动与健康科学(英文)》2020,9(6):645-650

BackgroundOne-hour postprandial hyperglycemia is associated with increased risk of type 2 diabetes and cardiovascular disease. Physical activity (PA) has short-term beneficial effects on post-meal glucose response. This study compared the oral glucose tolerance test results of 3 groups of people with habitually different levels of PA.MethodsThirty-one adults without diabetes (age 25.9 ± 6.6 years; body mass index 23.8 ± 3.8 kg/m²; mean ± SD) were recruited and divided into 3 groups based on self-reported PA volume and intensity: low activity < 30 min/day of moderate-intensity activity (n = 11), moderately active ≥ 30 min/day of moderate-intensity PA (n = 10), and very active ≥ 60 min/day of PA at high intensity (n = 10). Participants completed an oral glucose tolerance test (50 g glucose) with capillary blood samples obtained at baseline, 15 min, 30 min, 45 min, 60 min, 90 min, and 120 min post-ingestion.ResultsThere were no significant differences between groups for age or body fat percentage or glycated hemoglobin (p > 0.05). The groups were significantly different in terms of baseline glucose level (p = 0.003) and, marginally, for gender (p = 0.053) and BMI (p = 0.050). There was a statistically significant effect of PA on the 1-h postprandial glucose results (p = 0.029), with differences between very active and low activity groups (p = 0.008) but not between the moderately active and low activity groups (p = 0.360), even when baseline glucose level and gender differences were accounted for. For incremental area under the curve there was no significant effect of activity group once gender and body fat percentage had been accounted for (p = 0.401). Those in the low activity group took 15 min longer to reach peak glucose level than those in the very active group (p = 0.012).ConclusionThe results suggest that high levels of PA have a beneficial effect on postprandial blood glucose profiles when compared to low and moderate levels of activity.  相似文献   

Early Childhood Parenting Predicts Late Childhood Brain Functional Connectivity During Emotion Perception and Reward Processing     

Daniel C. Kopala-Sibley  Marilyn Cyr  Megan C. Finsaas  Jonathan Orawe  Anna Huang  Nim Tottenham  Daniel N. Klein 《Child development》2020,91(1):110-128

Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7–8 years later.  相似文献
