Effects of trait and situational self-handicapping on competitive anxiety among athletes

Initial evidence suggests that the employment of self-handicapping strategies has a beneficial effect on negative affective states associated with the perceived threat of evaluative contexts (Harris & Snyder, 1986; Leary, 1986). The present study sought to describe the type of self-handicapping behaviors demonstrated by youth athletes (N=238) as well as to assess the stress-buffering role of athlete self-handicapping on indices of competitive state anxiety. Specifically, it was hypothesized that among high trait-handicapping athletes, those who report a greater degree of performance-debilitating obstacles prior to competition would demonstrate lowered cognitive and somatic state anxiety as well as greater state self-confidence than nonhandicapping athletes. However, MANOVA results indicated that both high trait and situational self-handicappers demonstrate elevated state anxiety immediately prior to competition. Results are discussed in relation to the possible role of state anxiety as a salient self-handicapping strategy within competitive sport.     

刺激属性对内隐社会知觉的影响

本文通过选择不同词性（消极词、积极词和中性词）的双字词64个,主要对“刺激属性”变量进行了实验操作;采用“意识过滤”技术和速示辨认测验对内隐社会知觉的特点进行了考察;结果发现,实验材料的笔划数和被试的性别对内隐社会知觉没有影响,刺激的特性和刺激的启动作用对内除社会知觉有显著的影响;同时还证明速示辨认测验不受意识的“污染”,将速示辨认作为内臆测验的方法是比较“纯净的”。     

The effects of symmetry and contour on recognition memory in children

Children in prekindergarten, kindergarten, and second grade were tested on a delayed match-to-sample task using abstract visual patterns. The patterns varied both in type of visual organization (unstructured, diagonally symmetrical, vertically symmetrical, and horizontally symmetrical) and in amount of contour. Following the initial memory task, we attempted to train half of the children at each grade by directing their attention to axes of symmetry; the other half of the children received a control task. Subsequently, the subjects were given a second delayed match-to-sample test. On both pre- and post-training trials, structure influenced performance, especially in the two younger groups. Vertical and horizontal symmetry generally facilitated performance in the prekindergarteners, while all three types of symmetry facilitated performance in the kindergarteners. In addition, children generally responded more accurately to patterns with lower levels of contour. They also made more like-contour than unlike-contour confusions, indicating that quantitative aspects of patterns were encoded. Group differences suggested that both processing capacity and memory increase during the age range studied. Finally, there was no indication that training improved performance at any age.     

20—36.5米氮氧饱和及50-70米空气巡回潜水模拟实验的神经和心理功能研究

儿童最初词汇的获得及其过程

本文追踪研究了两名儿童获得最初词汇的过程。结果表明:在儿童最初语音发展过程中,所发出的音节日益丰富、分化,产生了连续音节,随意性和指向性逐渐增强。儿童获得最初词汇的过程,是连续音节逐渐被有指向的词取代的过程。根据连续音节和有指向的词的比例及沟通作用的变化,儿童获得最初词汇的过程可分为各具特点的三个阶段。两名儿童的最初词汇在其词类构成和功能意义上具有很高的一致性。结合两名儿童之间的个别差异,本文还初步探讨影响儿童获得最初词汇的因素——言语中枢和言语器官的发展、认知的发展,并探讨它们之间可能存在的相互关系。     

Emotional labour strategies and job burnout: A meta-analysis of Chinese employees

Emotional labour strategies have a significant impact on job burnout. However, current research results are controversial and unclear. A meta-analysis was conducted to explore the relationship between emotional labour strategies (surface acting and deep acting) and job burnout. A total of 84 empirical studies that included 28,242 participants were selected. The meta-analysis of the relationships between job burnout and surface acting and deep acting included 84 and 75 independent samples respectively. The results show that surface acting had a positive association (r = 0.25) with job burnout, whereas deep acting (r = −0.27) had a negative association with job burnout. Occupational types and measures of emotional labour strategies moderated the relationship between emotional labour strategies and job burnout, but this relationship was not moderated by measures of job burnout.     

认知发展研究趋势的探讨

该文阐明了认知科学、建构主义和新皮亚杰学派对认知发展研究的影响,着重论述了新皮亚杰学派对认知发展研究的新趋势及主要观点,并对这些趋势予以了较为详尽的评述,以期为认知发展心理学家重新审视和思考原有认知发展理论假设的合理性、提出新的假设和新的研究方向有所启示。     

抗血管生成与肿瘤休眠疗法

回顾抗血管生成与肿瘤休眠疗法的进展,研究肿瘤未成熟血管与实体肿瘤的关系,探讨抗血管生成疗法在肿瘤生长和转移中的作用。肿瘤新生血管在肿瘤的生长和转移中均有重要意义。现已证实,肿瘤的生长和转移具有血管依赖性,实体肿瘤生长至一定体积需要通过新生成的血管灌注获得营养,而且新生的未成熟血管结构缺陷,通透性增加,使得肿瘤 容易穿透而发生血行转移。     

学生学业和行为特征如何影响教师支持？来自个体和圈子层面的证据

教师支持是师生关系的重要指标,由教师和学生共同建构;学生的学业和行为特征会影响教师支持,但是以往研究主要关注学生个体特征的影响,极少考察学生所在小群体的作用。本研究以个体和其所在圈子的学业成就、亲社会行为、攻击行为为特征,考察其对教师支持的影响,结果发现：（1）个体的学业成就积极预测后续教师支持的增加;（2）在高学业成就圈子中,个体学业成就的提高能够预测教师支持的增加,而在低学业成就圈子则不能;（3）与男生相比,在低亲社会圈子中的女生获得的教师支持更少,而在高亲社会圈子中的女生则能够获得比男生更高的教师支持。     

Gender Differences in the Creativity–Academic Achievement Relationship: A Study from China

This study investigated gender differences in the relationship between creativity and academic achievement. A sample of 1082 primary students participated in this study in Beijing, China. Their age ranged between 8 and 15 years old (M = 10.41, SD = 0.99). Students’ creativity was measured by the Chinese version of the Torrance Test of Creative Thinking Figural Form A, and academic achievement was based on students’ self-reported grades of last semester. Results revealed that there was a significantly positive relationship between creativity and academic achievement, ranging from r = .07 to r = .21. Gender differences regarding which aspects of creativity were related to academic achievement were also found. Plausible explanations and implications of the findings in creativity research and education are discussed.
