Predictive models for understanding body dissatisfaction among young males and females in China

The present study was designed to develop predictive models for understanding body dissatisfaction among young males and females (N=1377) in China. Six factors were assessed, including body mass index (BMI), perception of teasing, social pressure to be thin, appearance comparison, thin-ideal internalization and perceived social support. Variables were examined respectively for males and females. One SEM model, which had good fit indices, was developed for each gender. For both genders, BMI exerted its influence on body image directly and indirectly through perception of teasing. Two sources of sociocultural influence, perception of teasing and social pressure to be thin, also directly predicted body dissatisfaction. Gender differences were found in the relation between mediational mechanisms (social comparison and thin-ideal internalization) and body dissatisfaction. For females but not males, social comparison and internalization acted as weak but significant mediators between sociocultural influence and body image concerns. Implications and limitations are discussed.     

不同教师群体激励因素的比较研究

本研究选择云南曲靖和浙江宁波的两所师范学校作为研究对象,以教育人种学研究方法为基本方法,通过现象分析、个案访谈、问卷调查、文献分析等途径,对不同地区教师群体的工作积极性状态及其原因进行了实证性对比研究,得出以下结论:竞争压力和相对报酬之间的相互关系是决定不同教师群体工作积极性大小的两个关键因素。其中竞争因素的激励功能相对较强。竞争压力大小与相对报酬高低之间的相互关系影响着群体激励力量的大小。     

不同干预方式、不同应激源对血压、心率的影响

探讨不同干预方式、不同应激源对血压、心率影响的差异。被试为本科生48人,采取干预方式、应激源、实验间期的三因素混合实验设计。干预方式为放松训练和预知,应激源为心算和恐怖影片。实验间期包括基线期、干预期、应激期、恢复期。实验的因变量为每个实验间期的血压和心率。结果显示,心算应激引起的血压和心率升高显著高于恐怖影片应激引起的血压和心率的升高;放松训练组和预知组其干预期的血压和心率值都低于基线期;干预方式和应激源在血压和心率两个指标上交互作用不显著。结果表明,与恐怖情绪引起的紧张相比较,智力操作紧张更容易影响血压和心率;放松训练和预知对于对抗应激时血压和心率升高都起到了一定的作用;不同干预方式对于不同性质的应激源作用没有差别。     

Mean recovery rate: A simple measure of recovery uncontaminated by the carryover effect

Assessment of recovery is important for the investigation of stress but has been compounded by difficulties, in particular contamination by the carryover effect. In the present study, the mean recovery rate ( MRR ) was used in order to overcome this difficulty. First, the validity of the MRR was demonstrated theoretically. Second, it was demonstrated experimentally, when a comparison was made with the validity of the mean recovery per se. In the experiment, data on beat-by-beat systolic blood pressure, obtained from 18 participants before, during, and after mental arithmetic, were used as a typical sample. The implications of these results for the understanding of recovery measures are discussed.     

Does game pressure affect hand selection of NBA basketball players?

PurposeThe purpose of this study was to compare hand selection and accuracy of technical skills between low- and high-pressure games of the National Basketball Association (NBA) in the 2018–2019 regular season and playoffs.MethodA notational analysis was conducted on 24 games of four teams (12 low-pressure games and 12 high-pressure games, six of each team, three in each condition). One- or two-handed actions were recorded for dribbling, passing, catching, and shooting (layups, dunks, hooks, and tips) skills.ResultsDuring high-pressure games, players significantly increased the frequency of right-handed passing. High-pressure games also increased the frequency of left-handed catching. For dribbling and shooting, no differences were observed in hand frequency between conditions. The success rate of all analyzed skills was similar between the hands in both low- and high-pressure conditions.ConclusionOur results showed that game pressure could selectively modulate hand preference for passing and catching skills in elite-level basketball while presenting no significant effect on performance between hands.     

More than Bullshit: Trash Talk and Other Psychological Tests of Sporting Excellence

ABSTRACT

Sporting excellence is a function of physical, cognitive and psychological capacities: its standard requires demonstration of superlative physical and strategic skills and the performance of these skills under pressure. However, despite the widespread acceptance of this idea there has been little exploration of what counts as a legitimate test of the psychological dimension. What work has been done has tended to focus on the practice of trash talking and whether the pressure that trash talking exerts is conducive to sporting objectives. However, not only do we believe that the philosophical work on trash talking is misguided, but also its conclusions have not been used to elucidate the legitimacy of other psychological pressures that occur in sport. In this paper we address this first lacuna by providing a more nuanced exploration of trash talking than exists in the philosophical literature, with the aim of addressing the second lacuna by suggesting a framework by which to evaluate other forms of psychological pressure that arise in sport. Briefly, our claim is that not all forms of trash talking that derail an opponent degrade, and that recipients of trash talking have both epistemic and social responsibilities in how they respond to trash talking. Moreover, these epistemic and social responsibilities can be extrapolated to evaluate the legitimacy of other forms of psychological pressure in sport, with forms that turn out to preclude broader social ends being morally illegitimate, and forms that do not preclude social ends yet facilitate meaningful challenges being legitimate tests of sporting excellence.     

组织中绩效压力的双刃剑效应

市场经济的复杂多变给组织生存与发展带来诸多挑战,组织往往对员工提出高的绩效要求,绩效压力已成为普遍现象。现有研究大多关注绩效压力的消极效应,存在忽视其积极结果及理论视角较窄等不足。因此,系统、全面地认识绩效压力的双刃剑效应,有助于组织充分发挥绩效压力的积极效应及阻遏其消极效应。通过系统地回顾和梳理相关研究,在将绩效压力影响效果的研究分为积极、消极和二者并存的曲线效应三个类别后,引入压力认知评价理论、资源保存理论等理论厘清研究背后的解释机制。最后,基于以上梳理分析,未来研究应进一步拓展组织中绩效压力的双刃剑效应及其边界条件,从而更全面地认识组织中绩效压力所产生的影响。     

公仆型领导的负面效应及其缓冲机制探究

过去,研究人员普遍认为公仆型领导是一种对员工、团队和组织有积极作用的领导方式,但新近的研究表明公仆型领导也会引起潜在的负面效应。针对此问题,首先介绍公仆型领导的概念与研究概况。然后,分别从领导者自身和下属员工的角度,基于角色压力、自我控制资源分配、资源保存、内隐追随、领导与成员交换、领导原型等理论,探究公仆型领导的负面效应及其缓冲机制。最后,从研究层面、研究方法、研究视角、研究内容等四个方面提出未来研究建议。     

中学生学习主观幸福感及其影响因素的初步研究

以910名从初一到高三的中学生为被试,采用自编的《中学生学习主观幸福感量表》进行研究。结果表明:(1)中学生学习主观幸福感普遍偏低,且存在学校类型、年级的差异,非重点学校学生学习主观幸福感更低;高二、初二学生学习主观幸福感最低。(2)影响中学生学习主观幸福感的直接因素是学习体验和现有学习成绩,其中,前者作用更大。(3)影响中学生学习主观幸福感的间接因素是社会压力和希望学习成绩,它们通过学习体验或现有学习成绩间接作用于学习主观幸福感。     

The desire to win: The effects of competitive arousal on motivation and behavior

The paper theoretically elaborates and empirically investigates the “competitive arousal” model of decision making, which argues that elements of the strategic environment (e.g., head-to-head rivalry and time pressure) can fuel competitive motivations and behavior. Study 1 measures real-time motivations of online auction bidders and finds that the “desire to win” (even when winning is costly and will provide no strategic upside) is heightened when rivalry and time pressure coincide. Study 2 is a field experiment which alters the text of email alerts sent to bidders who have been outbid; the text makes competitive (vs. non-competitive) motivations salient. Making the desire to win salient triggers additional bidding, but only when rivalry and time pressure coincide. Study 3, a laboratory study, demonstrates that the desire to win mediates the effect of rivalry and time pressure on over-bidding.
