基于认知机制的有条件自动驾驶接管中的人因问题

自动驾驶能在很大程度上缓解现代交通问题并提升驾驶舒适度。有条件自动驾驶下, 驾驶员可执行非驾驶相关任务但需要在系统无法处理的状况下接管车辆。在这一关键过程中, 驾驶员需要进行注意转换并获得情境意识以成功接管。已有研究表明, 接管请求、非驾驶相关任务、驾驶情景及驾驶员因素是影响接管过程重要因素。未来可从认知机制角度研究各因素对接管过程产生的影响, 以及探究接管过程中各因素之间可能存在的交互作用。     

社会距离和性别对公平关注的影响

本研究使用单次匿名最后通牒博弈任务,采用2（性别: 男性, 女性）×3（社会距离: 自我决策, 替朋友决策, 替他人决策）×5（提议类型: 1/9, 2/8, 3/7, 4/6, 5/5）的混合实验设计,通过操作反应者的不同社会距离,考察资产分配情境下自我-他人决策的性别差异。研究结果发现：（1）相比于自我决策和替朋友决策,女性被试替他人决策时更愿意接受提议1/9,2/8和3/7,而提议4/6和5/5的接受率不受社会距离的影响;男性被试中社会距离和提议类型的交互作用不显著;（2）不平等提议的反应时随社会距离增加而逐渐降低,而平等提议的反应时不受社会距离的调节;（3）替他人决策时女性的接受阈限显著低于男性,而自我决策及替朋友决策时接受阈限不存在性别差异。     

航线飞行员危险态度测量及对驾驶安全行为的影响

为了探讨现代航线飞行员危险态度特点及其与驾驶安全行为的关系,采用文献分析、问卷调查和专家访谈,编制了中国文化背景下航线飞行员危险态度问卷,并对中国南方航空公司257名飞行员进行调查。结果发现,自信、冲动性、男子气概、焦虑、服从性和风险意识等因素能解释飞行员危险态度总体变异的60.275%,同时对驾驶安全行为产生显著负向影响。这一结果表明六维结构模型具有较好的信度和效度,可以作为现代航线飞行员驾驶安全行为评估的预测指标。     

n-back任务下视觉工作记忆负荷研究

实验采用n-back范式,考察了视觉工作记忆负荷与反应时、辨别力和主观评价的关系,以及空间位置记忆负荷与图形记忆负荷的差异。结果发现,随着记忆负荷的增大,反应时延长,辨别力降低,主观负荷提高。视觉图形记忆任务的负荷水平高于视觉空间位置记忆任务的负荷水平;同时也为视觉图形记忆和视觉空间记忆具有不同的加工过程提供了证据。     

Examining Effects of Self-Efficacy on Research Motivation Among Chinese University Teachers: Moderation of Leader Support and Mediation of Goal Orientations

Utilizing the Social Cognitive Career Theory (SCCT) as the theoretical framework, this study proposed a moderated mediation model investigating the complex functioning mechanisms of how self-efficacy beliefs and leader support can be related to research motivation among Chinese university teachers. A group of 310 Chinese teachers working in different universities completed an online survey. Results from structural equation modeling (SEM) analysis revealed distinct influencing paths from the predictor variables (i.e., self-efficacy and leader support) to the outcome variables (i.e., intrinsic and extrinsic research motivation). Specifically, self-efficacy beliefs predicted both mastery and performance goal orientations; mastery goal orientation, in turn, positively affected intrinsic and extrinsic research motivation. In contrast, leader support was non-significant for the both types of goal orientations, but exerted strong direct influences on the both types of research motivation. Bootstrapping methods in SEM showed that it was primarily the mastery goal orientation that mediated the relationships between self-efficacy beliefs and research motivation. Furthermore, the results from the SEM and simple slope analysis revealed that leader support moderated the association between self-efficacy and extrinsic research motivation.     

你和上司合拍吗?组织中的上下级匹配

上下级匹配, 作为影响领导-下属良性互动的关键因素, 近几年逐渐成为组织管理研究中的前沿话题。上下级匹配是指领导和下属在心理或行为特征方面的契合度, 包括一致性匹配和互补性匹配两种类型, 其测量方式也涉及直接测量与间接测量。从现有文献来看, 研究者主要考察了领导-下属在人格特质、社会认知、心理状态、工作行为和关系因素等方面的匹配效应, 涉及心理过程和互动过程两大中介机制, 个体因素和情境因素两大调节机制。未来研究可以关注传统性、面子意识等本土心理特征的匹配效应, 或者对现有的中介、调节机制进行拓展。     

Does snobbish service generate better sales? The case of luxury goods

The objective of this study is to explore whether a “bad” service encounter triggers a consumer's impulse purchase in a luxury goods store in an Asian emerging market. A 2 (service encounter: favorable vs. snobbish) × 2 (shopping companion: alone vs. with a close friend) between‐group factorial design was employed with 160 female consumers in an Asian emerging market to examine the antecedents of both the urge to save social identity and the impulse purchase of luxury goods. The results show that consumers in an Asian emerging market can be triggered to make an impulse purchase of a luxury good, not because they received excellent service in the store but because they encountered snobbish service, especially when shopping with a close friend. Research implications and limitations are also discussed.     

The Bibimbap Migration Theory? Challenges of Korea’s Multicultural Mix and Social Integration Development

Migration was never a brand new phenomenon in South Korea, but its migration pattern has been redirected, migrant size has been amplified, and migrant ethnicity has been diversified in recent years. Korea is undergoing dramatic changes in its demographic composition with an increasing presence of foreigners since the 1990s. Traditionally known for its cultural uniqueness and ethnic homogeneousness, the ongoing inflow of foreigners has presented new challenges, as to who the Koreans are and how the modern Korean society should be defined. Some Koreans even raise concern over migration inflow as a threat to its nationhood purity. This research examines the shifting trend of immigration in Korea with a focus on the new social development of multiculturalism, while assessing the level of social integration and multicultural discourses of the public. In addition to those widely discussed marriage immigrants and foreign labor workers in the existing literature, the recent surge of professional expats, foreign teachers, and international students is becoming evident in Korea’s multicultural mix. Moreover, there is still a lack of literature on foreign migrants in Korea, including the US military service personnel, the foreign professional sports players, non-North Korean international refugees, and the latest, permanent residency immigrants through property investment in Korea. Despite the noted increasing inflow of a variety of immigrant residents, who are constantly shaping the new faces of Korea, the acceptance of ethnic diversity and cultural integration has yet to secure its solid place in the Korean society for multiculturalism to be truly embraced and flourished.     

Experimental Power for Indirect Effects in Group-randomized Studies with Group-level Mediators

Mediation analyses have provided a critical platform to assess the validity of theories of action across a wide range of disciplines. Despite widespread interest and development in these analyses, literature guiding the design of mediation studies has been largely unavailable. Like studies focused on the detection of a total or main effect, an important design consideration is the statistical power to detect indirect effects if they exist. Understanding the sensitivity to detect indirect effects is exceptionally important because it directly influences the scale of data collection and ultimately governs the types of evidence group-randomized studies can bring to bear on theories of action. However, unlike studies concerned with the detection of total effects, literature has not established power formulas for detecting multilevel indirect effects in group-randomized designs. In this study, we develop closed-form expressions to estimate the variance of and the power to detect indirect effects in group-randomized studies with a group-level mediator using two-level linear models (i.e., 2-2-1 mediation). The results suggest that when carefully planned, group-randomized designs may frequently be well positioned to detect mediation effects with typical sample sizes. The resulting power formulas are implemented in the R package PowerUpR and the PowerUp!-Mediator software (causalevaluation.org).     

Why did adolescents have sleep problems after earthquakes? Understanding the role of traumatic exposure,fear, and PTSD

To examine the relationships between trauma exposure, fear, post‐traumatic stress disorder, and sleep problems in adolescents, 746 adolescent survivors of the 2008 Wenchuan earthquake in China were assessed at 1 year (T1) and 1.5 years (T2) after the earthquake using a trauma exposure questionnaire, a fear questionnaire, a child posttraumatic stress disorder symptom scale, and a subscale on child sleep problems. The results showed that T1 trauma exposure were not directly associated with sleep problems at T1 and T2, but played a positive role in sleep problems at both T1 and T2 indirectly through T1 posttraumatic stress disorder and T1 fear. T1 trauma exposure was also positively and indirectly associated with T2 sleep problems through T1 posttraumatic stress disorder via T1 sleep problems, or through T1 fear via the path from T1 posttraumatic stress disorder to T1 sleep problems. These findings indicated that fear and posttraumatic stress disorder 1 year after the earthquake played a mediating role in the relationship between trauma exposure at 1 year after the earthquake, and sleep problems at both 1 year and 1.5 years after the earthquake, respectively. In particular, posttraumatic stress disorder also had a multiple mediating effect in the path from trauma exposure to sleep problems via fear. Furthermore, the findings indicated that sleep problems were relatively stable between 1 and 1.5 years after an earthquake.
