The effects of mindfulness training on beginners' skill acquisition in dart throwing: A randomized controlled trial

ObjectivesThe present study was into whether or not mindfulness training, based on the mindfulness-acceptance-commitment approach (MAC), can improve beginners' skill acquisition of dart throwing.DesignRandomised controlled trial.MethodsA total of 43 first-year college students who had not played darts professionally prior to the study were randomly assigned to either an attention control group (n = 21) or a mindfulness training group (n = 22) during an eight-week dart training program. Dart throwing and psychological variables were assessed at pre-intervention, post-intervention, and two-week follow-up.ResultsTwo-way repeated measures ANOVA revealed that the mindfulness group, but not the attention control group had significant improvements in mindfulness, experiential acceptance, and flow at post-intervention and follow-up. Although both groups improved dart throwing performance after the intervention, the improvement of the mindfulness group was statistically higher in comparison to that of the attention control group.ConclusionsIt was concluded that the MAC approach could improve the performance and adaptive sport experience of beginners in dart throwing.     

隐性知识的具身机制、转化与管理

隐性知识是知识经济时代的发展关键,在多个学科的知识体系中占有重要位置。由于隐性知识有内隐表征、主观经验和情境性等多种跨层属性,导致管理学、体育学等学科面临隐性知识转化与管理的难题。隐性知识本质上是具身性的,身体经验与情境的互动为个体在知识系统中归纳与形成隐性知识提供了基础。隐性知识的提取与应用机制为组织对隐性知识的转化与管理提供了桥梁,而隐性知识的具身机制是其提取与应用的依据。本文将基于具身认知理论,结合多个学科的研究证据,对不同情境下的隐性知识提取与应用机制进行分析,旨在梳理出隐性知识的具身机制,并针对隐性知识的未来研究、转化与管理提出建议。     

Patterns in perceived crash risk among male and female drivers with and without substantial cycling experience

Perceived risk of crashes is generally higher in female than in male cyclists. No study has assessed whether these gender differences only apply to riding bicycles. Using an online risk assessment task and survey, this study (a) tested the hypothesis that compared to men, women perceive higher risks, irrespective of traffic mode and (b) explored gender differences in the predictors of perceived risk. Data were analysed from 595 driver licence holders in Australia: 444 who cycled regularly, termed ‘cyclists’ from here on (31% women) and 151 regular drivers who did not (63% women), who are referred to as ‘drivers’. Cyclists in their role as cyclists and drivers in their role as drivers (traffic role) were instructed to imagine being in a specified traffic scenario and to assess crash likelihood. Each of 6 traffic scenarios was presented twice but differing in configuration: a violating car and a violating bicycle. A mixed ANOVA, with rated probability of a crash as the dependent variable, gender and traffic role as grouping factors, and configuration as the repeated measure, resulted in a main effect of configuration, showing that both drivers and cyclists perceived higher levels of risk of violating cars than of violating bicycles (η_p2 = 0.34). The interaction of traffic role and configuration showed this difference to be smaller for drivers than for cyclists (η_p2 = 0.18). This suggests that drivers are aware of the car’s high injury potential in crashes with cyclists. The main effect of gender showed that irrespective of traffic role, women perceived higher risk than men, which supported the hypothesis that gender differences are not limited to cycling (η_p2 = 0.03). The main effect of traffic role was not significant.For the predictors of perceived risk, ANOVA showed main effects for traffic role and gender, with small effect sizes (from η_p2 = 0.02 to η_p2 = 0.03). Cyclists were more confident, less inattentive and more in favour of stricter laws. Women felt less skilled and were more concerned about risks. None of the interactions between gender and traffic role were significant, which lent further support to the hypothesis that gender differences were a general rather than a cycling specific characteristic. Thus, perceived risk does not differ between women who regularly cycle and those who do not. These findings may inform interventions about the role of perceived risk in the uptake of cycling.     

词汇预测性对中文高、低阅读技能儿童眼动行为的影响

操纵目标词的预测性、词频和阅读技能水平,考察句子阅读中词汇预测性对高、低阅读技能儿童眼动行为的影响,揭示其在儿童阅读发展中的作用。结果显示：儿童对高预测词的跳读率更高、注视时间更短,且预测性与词频交互影响跳读率和注视时间;预测性对高阅读技能儿童早期的跳读率影响更大,而对低阅读技能儿童晚期的再阅读时间具有更大影响。结果表明：词汇预测性影响儿童阅读的眼动行为和词汇加工,且作用大小和发生时程受阅读技能调节。     

精诚合一:医学哲学事业的永恒主题

医学哲学事业的价值在于发现并弘扬医学的基本精神。“精诚合一”是医学亘古不变的基本精神。当代医学哲学研究的任务是揭示医学的“精诚合一”特征及其深刻内涵,注重“精”与“诚”的有机结合,批判现实医疗活动和理论研究在“精”、“诚”问题上的片面,弘扬医学的基本精神。     

职业评定量表(VIESA)的信度和效度研究

根据D.E.Super的职业发展理论,职业选择的成熟与发展一般分为五个阶段,中学生正处在从探索到成熟的重要转变期。本研究以美国大学测验中心的职业分类系统为基础,以职业评定量表VIESA为工具和对象,对北京市第六十五中学的179名高中三年级学生和北京师范大学心理学系的55名二年级学生进行了施测,检验了量表的信度和效度。量表的信度指标基本在.70以上,构想效度良好,以专业满意感为效标的效标效度达到显著水平。     

组织中的政治技能及相关研究

政治技能是个体在工作中影响他人以实现组织目标的能力,对个体的工作绩效和某些工作态度、缓解工作中压力带来的紧张感等具有一定的作用。个体的洞察力、控制、亲和力、主动影响及发展经验被视为政治技能的影响因素,通过实践练习、替代学习等方法可实现政治技能的培训和开发。在未来的研究中,对政治技能概念的理解、测量多源性等方面的问题还需要进一步的探讨     

政治与关系视角的员工职业发展影响因素探讨

通过对16家制造型企业中的343个员工、662个同事及343个直接领导的配对数据进行实证分析,文章探讨了员工的组织政治技能、政治知觉,以及他们与直接上司的关系对于员工职业发展的关系。多层线性分析模型（HLM）结果表明：员工的政治技能有助于促进其与领导之间形成良好的关系（guanxi）,并籍此积极影响个人在组织中的职业发展,员工－领导关系是政治技能与职业发展之间的中介变量。另外,组织政治知觉影响政治技能对领导关系的作用,在政治氛围浓重的组织中,员工－领导关系更易受到员工政治技能的影响

TEACHING BETWEEN-CLASS generalization OF TOY PLAY BEHAVIOR TO HANDICAPPED CHILDREN

In this study, young children with severe and moderate handicaps were taught to generalize play responses. A multiple baseline across responses design, replicated with four children, was used to assessthe effects of generalization training within four sets of toys on generalization to untrained toys from four other sets. The responses taught were unique for each set of toys. Acrossthe four participants, training to generalize within-toy sets resulted in complete between-class generalization in 11 sets, partial generalization in 3 sets, and no generalization in 2 sets. No generalization occurred to another class of toys that differed fromthe previous sets in that they produced a reaction tothe play movement (e.g., pianos). Implications for conducting research using strategies based on class interrelationships in training contexts are discussed.
