ABSTRACT Relative age effects (RAEs) are independent of specific cutoff dates that can vary from country to country. However, the consequences of changing the selection cutoff dates within a national sport organization are unknown. Further, the transition from international youth to senior representation is yet to be explored in rugby union. Thus, the aims of this article were twofold: Study 1 compared the birth quarter (BQ) distributions of the England Rugby Football Union (RFU) under-18 representatives based on September to August and January to December selection cutoff dates. Study 2 explored the BQ distributions within the RFU international development pathway through analyzing the under-18, under-20, and senior representatives, as well as the BQ distributions of youth players who were subsequently capped at senior level. Chi-square analysis was used to compare BQ distributions in each sample against expected distributions. Results revealed a corresponding shift of a skewed birthdate distribution favoring chronologically older players that was mediated by specific cutoff dates (p < 0.05). Moreover, whilst RAEs were present within both youth cohorts (p < 0.05), it was not apparent at the senior level (p > 0.05). Furthermore, during the transition from international youth to senior representation, more chronologically older players were successfully capped.
相对年龄效应(RAEs)独立于特定截止日期,可能因国家而异。然而,在一个国家体育组织内改变选拔截止日期的后果是未知的。此外,在橄榄球联盟中,从国际青年代表到高级代表的过渡还有待探索。因此,本文的目的是双重的:研究1比较了英格兰橄榄球联盟(RFU) 18岁以下代表的出生季度(BQ)分布,基于9月至8月和1月至12月的选择截止日期。研究2通过分析u18、u20和成年球员的代表,以及随后进入成年球队的青年球员的BQ分布,探讨了RFU国际发展路径中的BQ分布。卡方分析用于比较每个样本的BQ分布与期望分布。结果显示,在特定截止日期的介导下,歪斜的出生日期分布发生了相应的变化,有利于年龄较大的球员(p < 0.05)。此外,尽管rae在两个青年组中都存在(p < 0.05),但在高级组中并不明显(p < 0.05)。此外,在从国际青年队到成年队的过渡过程中,更多年龄较大的球员成功入选国家队。

ABSTRACT Some research has investigated the big five personality dimensions among gifted individuals, but these individual studies have provided inconclusive results. The current meta-analysis examined the nature of the relationship between the big five dimensions and giftedness among individuals. Hedge’s unbiased g was used as the effect size metric, and a 3-level multilevel meta-analytic approach was applied, due to the dependency among the effect sizes obtained from the same study. The analyses used 82 effect sizes, from 13 published studies, and indicated that there was a significant difference between gifted and non-gifted participants in terms of Openness to Experience in favor of gifted individuals (g = .473, p = . 005, 95% CI [.199, .747]). However, there were no significant differences in terms of extraversion, agreeableness, conscientiousness, and neuroticism. The implications and limitations of the findings are discussed.
摘要一些研究调查了天才个体的五大人格维度,但这些个体研究提供了不确定的结果。目前的荟萃分析考察了五大维度与个人天赋之间关系的性质。Hedge的无偏g被用作效应大小度量,并且由于从同一研究中获得的效应大小之间的依赖性,应用了三级多水平元分析方法。该分析使用了来自13项已发表研究的82种效应大小,表明天才和非天才参与者在体验开放度方面存在显著差异,有利于天才个体(g=.473,p=.005,95%CI[.199,.747])。然而,在外向性、宜人性、尽责性和神经质方面没有显著差异。讨论了研究结果的含义和局限性。

ABSTRACT Physical activity plays an important role in individuals’ physical and psychological health. However, there is scarce evidence on how physical activity is associated with socioemotional aspects in gifted students. This is of special importance since previous research showed that gifted students scored significantly lower on physical self-concept when compared with their non-gifted peers. This study aimed to measure the associations between physical activity and different dimensions of academic, physical, and global self-concept in a sample of 10- to 18-year-old Spanish gifted students. It also investigated differences with non-gifted students on physical activity, self-concept, and their associations. The study involved measuring the physical activity levels of 219 gifted and 242 non-gifted students through PAQ-A, following a cross-sectional design. It relied on SDQ-II and CAF to measure academic, physical, and global self-concepts and included the importance accorded to self-concepts. Results showed that gifted students scored higher on academic self-concept and lower on self-perceived athletic ability. Physical activity was associated with better physical and global self-concepts, with no differences between gifted and non-gifted participants. No interactions between giftedness and physical activity appeared. Both samples’ self-concept may benefit from physical activity equally. Strategies for promoting physical activity should be endorsed also in gifted students.
体育活动对个体的身心健康起着重要作用。然而,很少有证据表明体育活动与天才学生的社会情感方面有关。这一点尤为重要,因为之前的研究表明,与非天才同龄人相比,天才学生在身体自我概念方面的得分明显较低。本研究旨在测量10至18岁西班牙天才学生的身体活动与学业、身体和全球自我概念不同维度之间的关系。它还调查了非天才学生在体育活动、自我概念及其关联方面的差异。该研究采用横断面设计,通过PAQ-A测量219名天才和242名非天才学生的体育活动水平。它依靠SDQ-II和CAF来衡量学术、身体和全球自我概念,并包括对自我概念的重视。结果显示,资优生在学业自我概念上得分较高,在自我感知运动能力上得分较低。体育活动与更好的身体和整体自我概念有关,天才和非天才参与者之间没有差异。天赋和身体活动之间没有相互作用。两个样本的自我概念可能同样受益于体育活动。促进体育活动的策略也应该在天才学生中得到认可。

ABSTRACT Rugby Sevens has been extensively investigated in elite athletes, but talented teenagers require more attention from sports development researchers. This study aimed to investigate a 16-week intervention of rugby training on physical performance in talented girls. Fifteen girls (14.00 ± 0.53 years, 156.27 ± 4.03 cm, 52.53 ± 5.67 kg) selected as physically talented for rugby to participate in a sport-development program were divided into two groups. The intervention group (IG) carried out two-session per week of rugby training for 16 weeks. The control group (CG) did not perform any type of physical training. A battery of physical tests was carried out before and after the intervention. A two-way ANOVA with group*time was carried out for analysis. Both groups increased their performance in countermovement jump, handgrip isometric strength, linear sprints, and 5-m multiple shuttle test (p < 0.05). However, squat jump, change of direction speed (CODS), and running anaerobic sprint test improved in IG (p < 0.05), while no difference was found in the CG. These results suggest that variables related to power output and CODS may be improved with the rugby training due to the specificity of the modality in talented girls.
摘要:七人制橄榄球已经在精英运动员中得到了广泛的研究,但有天赋的青少年需要更多的体育发展研究人员的关注。本研究旨在调查为期16周的橄榄球训练对天才女孩身体表现的干预。15名女孩(14.00±0.53岁,156.27±4.03厘米,52.53±5.67公斤)被选为橄榄球体能天才,参加体育发展计划,她们被分为两组。干预组(IG)每周进行两次为期16周的橄榄球训练。对照组(CG)没有进行任何类型的体能训练。在干预前后进行了一系列身体测试。采用组*时间的双向方差分析进行分析。两组在反跳、握力、直线短跑和5米多跳测试中的成绩均有所提高(p<0.05),而深蹲跳跃、转向速度(CODS)和无氧短跑测试在IG中均有所改善(p<0.05)。这些结果表明,与力量输出和CODS相关的变量可能会随着橄榄球训练而改善,因为这种模式在天才女孩中具有特殊性。

ABSTRACT This study used the bibliographic scattering analysis to explore the scientific publications trends on gifted individuals with autism spectrum disorders (ASD) over the past 23 years. The study examined the applicability and appropriateness of Bradford’s and Lotka’s laws of scattering to measure the impact factors of journals, institutions, countries, researchers, and personal publications on the area of research. After examining 95 research papers published in 55 Social Sciences Citation Indexed (SSCI) journals from 1998 to 2020. The rank list was prepared to identify the core journals in education. Themost frequent venues of journals in descending order of times cited are, Philosophical Transactions of the Royal Society B-Biological Science (USA) with 33.8% of citation, followed by the Journal of Autism and Developmental Disorders (USA) with 10.3% of citation and Journal of the American Academy of Child and Adolescent Psychiatry (USA) with 8.2% of citation. The top four categories of research were psychology with 37.13% of publications, followed by psychiatry (13.77%), neurosciences and neurology (11.38%), and education (8.38%). The study found that Asperger syndrome (AS) is still used in academic studies, even after it was immersed in the ASD by DSM-5 criteria. The findings and limitations were presented and discussed.
摘要本研究采用文献散射分析法,探讨了过去23年来关于自闭症谱系障碍(ASD)天才个体的科学出版物趋势。该研究考察了Bradford和Lotka散射定律的适用性和适当性,以衡量期刊、机构、国家、研究人员和个人出版物对研究领域的影响因素。在审查了1998年至2020年发表在55种社会科学引文索引(SSCI)期刊上的95篇研究论文后。编制排行榜是为了确定教育领域的核心期刊。按引用次数降序排列,最常见的期刊是《皇家学会哲学汇刊B生物科学》(美国),引用率为33.8%,其次是《自闭症和发育障碍杂志》(美国,引用率10.3%)和《美国儿童和青少年精神病学学会杂志》(美国),引用量8.2%。排名前四的研究类别是心理学,占出版物的37.13%,其次是精神病学(13.77%)、神经科学和神经病学(11.38%)和教育学(8.38%)。研究发现,阿斯伯格综合征(AS)仍然被用于学术研究,即使根据DSM-5标准,它被纳入了ASD。介绍并讨论了研究结果和局限性。

ABSTRACT Conditions influencing 328 students’ (Grades 6-8) preferences for collaborating or working alone on challenging projects were investigated, as well as their potential interactions with ability, grade and sex. Each student completed the Cognitive Abilities Test (Form 7) and Project Context Survey. No overall preference for individual or collaborative projects was found. Students’ preferences were sensitive to features of the context (subject, nature of the task and social dynamics). Individual projects were preferred in art and shared projects in science and social studies. Students with high ability and boys preferred individual projects in Math. Principal components analyses revealed three contextual considerations influenced students’ desire to work on projects alone (enjoyment, optimizing the outcome, and risk management) and five influenced the appeal of collaborating (inclusiveness and trust, access to the strengths of others, their perceived need for support, familiarity, and fair assessment). High ability students were more concerned with the efficiency and quality of their work, and their grades while others their age were more influenced by the potential for fun. Grade 8 students were more concerned with risk management and the assessment process than younger students. If the safe, supportive, fair conditions they sought for collaborating were not available, students’ default preference was to work alone on a challenging project.
摘要调查了影响328名学生(6-8年级)在具有挑战性的项目中合作或单独工作的偏好的条件,以及他们与能力、年级和性别的潜在互动。每个学生都完成了认知能力测试(中七)和项目情境调查。没有发现个人或合作项目的总体偏好。学生的偏好对环境特征(主题、任务性质和社会动态)很敏感。艺术领域的个人项目优先,科学和社会研究领域的共享项目优先。能力强的学生和男孩更喜欢数学方面的个人项目。主成分分析显示,三个情境因素影响了学生独自完成项目的愿望(享受、优化结果和风险管理),五个因素影响了合作的吸引力(包容性和信任、获得他人优势、他们对支持的感知需求、熟悉度和公平评估)。高能力的学生更关心他们工作的效率和质量,以及他们的成绩,而其他同龄人则更受乐趣潜力的影响。八年级学生比年轻学生更关心风险管理和评估过程。如果他们寻求的安全、支持和公平的合作条件不可用,学生们的默认偏好是独自完成一个具有挑战性的项目。

ABSTRACT This study aimed to analyze whether judo experience, somatic maturation, growth, and physical capacities discriminate young judo athletes from different competitive levels (state and national). Sixty-six young male judo athletes (36 from state and 30 from national level) participated in this study, divided from the annual competitive season. The assessments were performed in two stages separated by 48 hours: anthropometric measurements and physical tests (standing long jump – SLJ, medicine ball throw test-MBT, handgrip strength test – HGS, Special Judo Fitness Test – SJFT and Judogi Grip Isometric Strength Test–JGST). Judo athletes were asked for their date of birth and judo experience. T-test and discriminant analysis were used to compare and discriminate the variables between young judo athletes from state and national groups with the level of significance set at 5%. The main results showed that stature, judo experience, JGST, and SLJ performance were higher in the national group (p < 0.05) and could adequately discriminate competitive levels (structural coefficient >30, p < 0.001). It was concluded that young male judo athletes who compete at the national level are taller, more experienced, and present superior physical performance in tests related to strength and power than athletes from the state group of the same age.
摘要本研究旨在分析柔道经验、身体成熟、成长和体能是否能区分不同竞技水平(州和国家)的年轻柔道运动员。66名年轻男子柔道运动员(36名来自州,30名来自国家级)参加了这项研究,分为年度比赛季。评估分为两个阶段进行,间隔48小时:人体测量和身体测试(站立跳远-SLJ、药球投掷测试MBT、握力测试-HGS、特殊柔道体能测试-SJFT和柔道握力等距力量测试-JGST)。柔道运动员被问及他们的出生日期和柔道经验。采用T检验和判别分析对州和国家组青年柔道运动员的变量进行比较和判别,显著性水平设定为5%。主要结果表明,国家组的身材、柔道经验、JGST和SLJ成绩较高(p<0.05),能够充分区分竞技水平(结构系数>30,p<0.001),并且在与力量和力量相关的测试中表现出比同龄国家组运动员更好的身体表现。

ABSTRACT This literature review provides an overview of the various modern approaches in talent programs for the context of schools and sports reported in scientific journals (2009–2019) and presents their similarities and differences and options for cross-pollination between contexts. This is a first attempt to overarch contexts regarding talent identification and development. Searches in 12 databases yielded 31 studies. Similarities and differences between contexts were distilled through a qualitative content analysis and described for the identification of talent and talent development. Based on these results, it is suggested that school contexts might benefit from including a talent transfer pathway, differentiating for maturity-level and sex, emphasizing on deliberate practice, monitoring load-ability, and applying acceleration, which are proposed approaches in the sport context. Furthermore, several approaches from the school context could enhance talent programs in sport, including universal screening, paying attention to underserved populations, focusing on creativity and enrichment as well as enhancing the accountability and education level of trainers/coaches. Future studies need to evaluate the efficacy and feasibility of approaches in practice. Moreover, the search could be expanded to other countries to establish a more global view while examining national patterns regarding policy and funding contexts in which programs are located.
摘要这篇文献综述概述了科学期刊(2009-2019)上报道的学校和体育背景下的各种现代人才计划方法,并介绍了它们的异同以及不同背景下的交叉授粉选择。这是对人才识别和发展背景的首次探索。在12个数据库中搜索得到31项研究。通过定性内容分析,提炼出语境之间的异同,并对其进行描述,以识别人才和促进人才发展。基于这些结果,建议学校环境可能受益于包括人才转移途径、区分成熟度和性别、强调深思熟虑的练习、监测负荷能力和应用加速,这些都是在体育环境中提出的方法。此外,学校背景下的几种方法可以加强体育人才计划,包括普及筛查,关注服务不足的人群,注重创造力和丰富性,以及提高培训师/教练的问责制和教育水平。未来的研究需要评估这些方法在实践中的有效性和可行性。此外,可以将搜索范围扩大到其他国家,以建立更全球化的观点,同时研究项目所在的政策和资金背景方面的国家模式。

ABSTRACT The aim of this study was to determine what kind of performance characteristics distinguish between different skill levels at different development stages in field hockey using a multi-dimensional testing battery. A total of 100 players identified as “talented” (51.0% girls) and 105 recreational level players (41.0% girls) divided over three age groups (U13/U15/U18) performed anthropometric, physical capacity, sport-specific technical skill and decision-making tests and completed self-regulation and sport history questionnaires. Gender specific multivariate analysis with playing level and age group as factors and age as a covariate were performed. Results revealed that experienced selectors and coaches select players for representative teams predominantly based on their dribbling skills, passing/hitting skills and speed and endurance. Furthermore, it is clear that selection for such a representative team is strongly influenced by maturational status and accumulated field hockey specific training hours. Interestingly, no differences were found between the self-regulatory skills of state and club level players for either gender. This study highlighted the performance characteristics deemed to be important by selectors and coaches and emphasized the need to consider the strong influence of maturational status and practice history when selecting “talented” players as these factors don’t translate to future sporting success.
摘要本研究的目的是使用多维测试组来确定曲棍球在不同发展阶段不同技能水平之间的表现特征。共有100名被认定为“天才”的球员(51.0%为女孩)和105名娱乐级别的球员(41.0%为女孩,分为三个年龄组(U13/U15/U18)进行了人体测量、体能、运动专项技术技能和决策测试,并完成了自我调节和运动史问卷调查。以比赛水平和年龄组为因素,年龄为协变量,进行了性别特异性多变量分析。结果显示,经验丰富的选拔人员和教练主要根据球员的运球技术、传球/击球技术以及速度和耐力为代表性球队挑选球员。此外,很明显,选择这样一支具有代表性的球队在很大程度上受到成熟状态和累积的曲棍球专项训练时间的影响。有趣的是,无论男女,州和俱乐部级别球员的自律技能都没有差异。这项研究强调了选拔人员和教练认为重要的表现特征,并强调在选择“有天赋”的球员时,需要考虑成熟状态和训练历史的强烈影响,因为这些因素不会转化为未来的体育成功。

ABSTRACT Gifted education in the Kingdom of Saudi Arabia has developed significantly since its tentative beginnings in 1969. Increasingly, however, there are concerns that gifted education is not meeting its objectives. Based on the Ziegler-Balestrini-Stoegerian framework, we evaluate Saudi gifted education from a macro-systemic perspective, including the identification of the ten important exogenous and endogenous capitals and the six principles (law of the minimum, continuity, developmental level, support systems, control system and external management). Using information obtained from 25 source documents, we conduct an automated content analysis using Leximancer to find information related to each of the ten capitals and six principles. Our finding that the absence of a clearly articulated set of objectives and expected outcomes impact the system on many levels, and that, at best, Saudi gifted education is best described as a proto-system.
沙特阿拉伯王国的资优教育自1969年试探性开始以来,已经有了显著的发展。然而,越来越多的人担心,天才教育并没有达到它的目标。基于Ziegler-Balestrini-Stoegerian框架,我们从宏观系统的角度对沙特的资优教育进行了评估,包括确定了10个重要的外生资本和内生资本以及6个原则(最小法则、连续性、发展水平、支持系统、控制系统和外部管理)。使用从25个源文档中获得的信息,我们使用lexximancer进行自动内容分析,以查找与10个大写字母和6个原则相关的信息。我们发现,缺乏一套清晰的目标和预期结果在许多层面上影响了这个系统,而且,充其量,沙特的天才教育最好被描述为一个原型系统。
