Personal characteristics as predictors for dual career dropout versus continuation – A prospective study of adolescent athletes from German elite sport schools

ObjectivesThe primary objective of this study is to identify the personal characteristics that predict dropout versus continuation among dual career athletes from different sports who attend sports schools. These schools provide an optimal environment for combining an academic education with a sports career.MethodsAt the end of the school year, all 10th graders (52 girls, 73 boys) from five out of six sports schools in Saxony, Germany, completed a standardised questionnaire that measured personal characteristics deemed important for a successful career – personality traits (Freiburger Persönlichkeitsinventar – FPI), goal orientation (Sport Orientation Questionnaire – SOQ), and volitional skills (Volitional Components in Sport – VKS). In addition, demographic and sport-related data were collected. One year later, at the end of 11th grade, all participants again completed the questionnaire.ResultsAt Time 2, 37 athletes (29.6%) had dropped out of their sport career, and 88 athletes were still pursuing their sport career. A majority of the dropouts were from individual sports (n = 31) and were females (n = 23). A logistic regression analysis of physical complaints (higher for dropouts), win motivation and self-optimisation (each lower for dropouts) as significant covariates correctly classified 65% of the dropouts and 92% of the non-dropouts.ConclusionsPersonal characteristics, motivation and volition in particular, played important roles for those adolescent athletes who remained active in their sport. Accordingly, it is suggested that young athletes receive psychological training focused on these specific personal characteristics.     

Longitudinal patterns of change in eye–hand coordination in children aged 8–16 years

Enhanced eye–hand coordination (EHC) is associated with greater participation in physical activity. No longitudinal studies have examined the change in throw–catch EHC from childhood to mid-adolescence. We investigated the development of EHC with an object control test from childhood to mid-adolescence in boys and girls. Evaluated at age 8, 10, 12 and 16 years, EHC was measured as the aggregate success rate of a throw and wall-rebound catch test. The test involved 40 attempts of progressive increasing difficulty, as determined by increased distances from a wall and transitions from two-handed to one-handed catches. Outcomes were treated as quasi-binomial and modelled by generalised linear mixed logistic regression analysis. EHC improved with age from childhood to mid-adolescence, although boys were more adept at each age (p < 0.001). The patterns of change in EHC with increasing age varied according to the degree of difficulty of the task (p < 0.001); throw and two-handed catch proficiency developing earlier than throw and one-handed catch in both sexes. Boys’ EHC was better than girls’ as early as age 8 years and male proficiency was maintained through to mid-adolescence. The proficiency of throw and two-handed catch rates developed faster than throw and one-handed catch rates for both sexes.     

What enhances the development of emotion understanding in young children? A longitudinal study of interpersonal predictors

We studied potential determinants of the development of children's emotion understanding (EU) from age 4 to 6 in a Norwegian community sample (N = 974) using the Test of Emotion Comprehension. Interpersonal predictors included the accuracy of parental mentalization, parental emotional availability, and teacher‐reported child social skills. Intrapersonal child factors were child gender and verbal skills. Overall, children's EU increased significantly over time. After adjusting for child gender, age‐4 EU, and parental socio‐economic status, greater child verbal and social skills and greater parental mentalization each uniquely predicted growth in EU. Results are discussed in terms of theory and research on children's EU and parents' emotion socialization.     

言语产生中的韵律生成

首先描述了韵律生成的相关模型。然后以研究的问题为着眼点,回顾了言语产生中韵律生成的相关研究。发现大多数研究结果都证明,在单词产生过程中,存在一个独立于音段内容的抽象韵律结构,其中包含了词的重音模式和音节数量等信息;在短语和句子产生过程中,韵律结构和停顿模式都不是完全决定于句法结构,而具有相对的独立性;句子韵律产生的最佳单位是韵律词。语言学韵律产生的脑区激活呈左侧化趋势。     

医学论文标题和摘要的英译特点

就医学论文标题的英译句式和书写,医学文摘的规格和动词时态的应用,常用句型的表达等等作了一一概述。说明医学标题和文摘的英译不是简单的单词与短语的对应堆积,而是按一定的句式、结构、语法特点,按照医学文摘写作的一些规律组织起来的。     

领导者底线心智对团队创新的双刃剑效应

底线心智是一种以获取底线利润结果为中心,而忽略其他一切竞争事项优先权(如企业社会责任、利益相关者权益、员工福利等)的单维思维模式。虽然底线心智可能导致管理者只注重绩效而忽视其他对企业有利的重要事项,甚至采取不道德的手段来实现目标,但研究也表明底线心智能够提高员工工作专注度进而提升绩效。为进一步推进底线心智双刃剑效应的研究,本文构建了领导者底线心智对团队创新双刃剑效应的影响机制模型,指出领导者底线心智一方面抑制了团队风险承担意愿,进而相比于探索式创新更有益于利用式创新;另一方面能够激发团队强迫激情,从而相比于团队创意产生更有利于团队创意实施。本文为深化底线心智领域的研究提供了参考,也为组织和领导者如何更好管理底线心智提供了重要建议。     

沃尔夫假说的新证据:范畴内和范畴间颜色辨别难度相同时语言范畴也会影响注意前颜色知觉

该研究探讨了当范畴内和范畴间颜色的辨别难度相同时,语言范畴是否会影响注意前颜色知觉。实验中,采用渐变且相邻者差别阈限数相当的A、B、C、D四种颜色（前两者为绿色,后两者为蓝色）为刺激材料,并让被试接受视觉Oddball脑电测试。脑电测试分视野给被试呈现标准刺激,以及与标准刺激属同一语言范畴（即颜色词绿色或蓝色）或不同语言范畴的偏差刺激。结果发现：在左视野呈现时,范畴内偏差刺激比范畴间偏差刺激诱发了边缘显著更大的视觉失匹配负波（vMMN）,在右视野呈现时,两类偏差刺激诱发的vMMN无显著差异;范畴内偏差刺激在不同视野呈现时诱发的vMMN无显著差异,范畴间偏差刺激则在右视野呈现时诱发了显著更大的vMMN。这一结果表明,当范畴内和范畴间颜色的辨别难度相同时,语言范畴也会影响早期的、注意前颜色知觉,支持了沃尔夫假说。
