College students were asked if they would be willing to serve as student contacts for high school students applying for admission to the university who wanted more information about student life. Students volunteered to spend more time helping a female applicant if she wanted to become a librarian than if she wanted to become an engineer, while they volunteered to spend more time helping a male applicant if he wanted to become an engineer than if he wanted to become a librarian. Results were the same when the dependent measure was the amount of time volunteered for interviews, for telephone conversations, and for letterwriting, indicating that the amount of personal contact required did not influence subjects' preference to help those whose career aspirations were sex-role appropriate more than those whose career goals were sex-role inappropriate.  相似文献

为证明年龄对老化的标识作用,研究假设降低被试的主观年龄可减少老年人的主观老化体验。采取实验组控制组前测后测设计,以主观年龄为自变量,分为"等于年代年龄"(控制组)和"小于年代年龄10±5岁"(实验组)两种水平,随机分配至两组的62名老年被试填写《个人老化体验问卷》,评估其主观老化体验。结果显示,实验组在后测中的主观老化体验不仅显著低于本组前测,也显著低于控制组,且这一结果不受被试最初自评的主观年龄影响。原假设得到证明,支持年龄对老化的标识作用。年龄标识对老化意义的简单化建构了世俗的绝对老化观。  相似文献

Using Louis’ formula, it is possible to obtain the observed information matrix and the corresponding large-sample standard error estimates after the expectation–maximization (EM) algorithm has converged. However, Louis’ formula is commonly de-emphasized due to its relatively complex integration representation, particularly when studying latent variable models. This paper provides a holistic overview that demonstrates how Louis’ formula can be applied efficiently to item response theory (IRT) models and other popular latent variable models, such as cognitive diagnostic models (CDMs). After presenting the algebraic components required for Louis’ formula, two real data analyses, with accompanying numerical illustrations, are presented. Next, a Monte Carlo simulation is presented to compare the computational efficiency of Louis’ formula with previously existing methods. Results from these presentations suggest that Louis’ formula should be adopted as a standard method when computing the observed information matrix for IRT models and CDMs fitted with the EM algorithm due to its computational efficiency and flexibility.  相似文献

Existing knowledge on remote working can be questioned in an extraordinary pandemic context. We conducted a mixed-methods investigation to explore the challenges experienced by remote workers at this time, as well as what virtual work characteristics and individual differences affect these challenges. In Study 1, from semi-structured interviews with Chinese employees working from home in the early days of the pandemic, we identified four key remote work challenges (work-home interference, ineffective communication, procrastination, and loneliness), as well as four virtual work characteristics that affected the experience of these challenges (social support, job autonomy, monitoring, and workload) and one key individual difference factor (workers’ self-discipline). In Study 2, using survey data from 522 employees working at home during the pandemic, we found that virtual work characteristics linked to worker's performance and well-being via the experienced challenges. Specifically, social support was positively correlated with lower levels of all remote working challenges; job autonomy negatively related to loneliness; workload and monitoring both linked to higher work-home interference; and workload additionally linked to lower procrastination. Self-discipline was a significant moderator of several of these relationships. We discuss the implications of our research for the pandemic and beyond.  相似文献

Over the past decades, employment rates of older workers in most Western countries have rapidly increased. Hence, there is a growing interest in identifying the organizational dimensions that might impact the psychosocial adjustment of workers aged over 50 years. This study focuses on perceived organizational support (POS) and identity-related measures (identification and authenticity) as key organizational components for workers at this stage of life. Furthermore, in the relationships discussed, we explore the moderating role of perceived age discrimination. In an ample sample of older workers (N = 4,563, aged 50–66 years), a moderated mediational model was tested where older workers' involvement was associated to POS. In the model, this relationship was mediated by organizational identification and authenticity, and the association between POS, identity-related measures, and involvement was moderated by age-based discrimination. Results showed that POS is associated with organizational involvement via organizational identification and authenticity and that high level of age discrimination decreased the positive association between POS, organizational identification, authenticity, and involvement.  相似文献

本文讨论了不同历史时期的心理学家对和平心理的看法,以“和平”为主线,追溯和平心理学思潮兴起的历史逻辑。毕达哥拉斯、恩培多克勒、柏拉图、奥古斯丁、夸美纽斯、康德等从本体论视角,确立了实现永久和平的理想追求。冯特的民族心理学重视研究原始人、战争英雄等的和平心理品质,早期的意动心理学重视人类和平意识研究,机能心理学强调通过建设学校“微型共同体”,提高儿童的和平意识。精神分析心理学则为战争与和平心理提供了新视角。人本主义心理学主张研究人的和平潜能、致力于世界和平冲突化解,推动了和平心理学的兴起。20世纪末的和平心理学主张用和平的方式实现和平,发生了“政治道歉”、和平冲突化解、“人类命运共同体”等研究趋向。  相似文献

本研究采用学习-再认范式和复杂数字记忆材料,考察自然数码奇象记忆法相对于机械记忆法在记忆提取上的优势及神经机制。行为结果表明,自然数码奇象记忆法比机械记忆法的再认准确率更高。事件相关电位分析结果显示,再认提取阶段奇象记忆条件下诱发的N400和N700波幅显著更低,这说明奇象记忆提取更容易。在自然数码奇象记忆条件下,正确再认旧数字诱发的前额区、左顶枕叶区及中顶枕叶区N700成分与使用自然数码奇象记忆有关。本研究表明,采用自然数码奇象记忆可以减少或跨越语义加工,从而提高个体对材料的记忆效率。  相似文献
