Effects of diversity versus segregation on automatic approach and avoidance behavior towards own and other ethnic groups

We present the results of a study in which we measured automatic intergroup behavior and evaluations in ethnic majority and minority group members. We focus our attention on the level of segregation and diversity of immediate life contexts as indicators of outgroup exposure. Specifically, Dutch ethnic minority and majority students enrolled at ethnically segregated and diverse schools completed a measure of automatic approach and avoidance behavior and reported explicit intergroup attitudes. The research is framed into prevailing theories in the field: Social Identity Theory and System Justification Theory. Results of our study suggest that segregation of minority group members' immediate life context may be an important moderator of evaluations as well as approach and avoidance behavior toward ingroup and outgroup. In particular, minority members in segregated schools showed an approach bias towards their ingroup, whereas minority members in diverse schools showed an approach bias towards the majority outgroup.     

孤独让我爱上你:产品陈列对孤独个体产品偏好的影响

研究通过3组实验分析产品陈列方式对孤独个体产品偏好的影响。实验1发现产品合并陈列时,孤独个体偏爱普通产品;产品单独陈列时,孤独个体更喜欢拟人化产品。实验2采用产品的功能关系代替陈列方式,进一步验证主效应。实验3分析广告信息类别对主效应的调节作用。本文为企业合理地使用拟人化策略提供建议。     

用药动作线索诱发海洛因戒断者的镜像神经活动:一项fMRI研究

相关线索能够诱发药物依赖者的心理渴求,而健康人不会对相关线索产生心理渴求。15名海洛因成瘾者和12名没有任何物质滥用的健康被试参与实验,收集了他们在观看相关线索与对照线索时的脑神经活动。结果发现,药物线索能够诱发戒断者更多脑区的活动,包括扣带回和楔前叶。两组被试在对照动作线索刺激诱发作用下,其颞叶、顶叶均出现了较为一致的活动。在用药动作线索诱发作用下,戒断组双侧颞中回、双侧顶下小叶、左侧顶上小叶和右侧额下回显示出显著活动,并且与对照动作线索激活脑区一致;健康组被试除枕叶-颞叶联合区外,没有出现显著的脑区活动。以上结果表明,用药动作线索诱发了海洛因戒断者颞中回、顶下小叶、额下回等镜像神经系统的活动,这些脑区对不同类型的相关线索十分敏感,它们可能通过对用药动作的心理模拟,参与了用药动作线索的快速自动化加工。     

WILLIAM WHEWELL,THE PLURALITY OF WORLDS,AND THE MODERN SOLAR SYSTEM

Astronomers of the first half of the nineteenth century viewed our solar system entirely differently from the way twentieth‐century astronomers viewed it. In the earlier period the dominant image was of a set of planets and moons, both of which kinds of bodies were inhabited by intelligent beings comparable to humans. By the early twentieth century, science had driven these beings from every planet in our system except the Earth, leaving our solar system (and perhaps others) as more or less desolate regions for the most part bereft of intelligent life. This essay traces this extinction and its relation to religious thought, noting the role played in it by Sir John Herschel and especially by William Whewell. The inverse square laws for gravitation, heat radiation, and light receive special attention, as does the question of the relevance of the Christian notions of a divine incarnation and redemption.     

Focusing on the emergencies or on their roots? The role of nonprofit organisations in immigration policymaking in Italy

Religious organisations are a relevant actor in immigration policymaking in Italy; they usually work in networks with institutions and other actors from the nonprofit sector to implement projects and services for migrants. However, the collaboration might lead to disagreement on which is the best way to face social problems related to immigration. In the province of Foggia, the reports on the precarious conditions of migrants employed in agriculture led to the development of a range of activities for improving their status and fighting their exploitation. While an issue network on the receipt and first assistance for migrants has arisen, there is no agreement on deeper interventions between nonprofit organisations (NPOs) which want to provide help for migrants in actual situations of precariousness and NPOs committed to face the causes of these situations. The tension between these two conceptions of nonprofit role in public policies might be divisive inside the religious associationism.     

Public health consequences of road traffic injuries – Estimation of seriously injured persons based on risk for permanent medical impairment

Despite the fact, that Sweden has one of the safest traffic environments in the world, a large number of people are still injured in road traffic accidents in Sweden. The core concept of the Vision Zero that was adopted by the Swedish parliament in 1997 is to decrease the number of deaths and serious injuries caused by traffic. The vision has been followed-up in terms of decreased mortality, but there was not a consensus on how the concept “seriously injured” should be measured at that time. The aim of this paper is to describe how to develop a measure to estimate the number of seriously injured people in Sweden. The results show that it is possible to estimate the health impact of road traffic accidents based on the definition of medical impairment. According to the results, 8389 people were seriously injured (permanently medical impaired more then 1%) in the road transport area in Sweden in 2013. If the number of people who had slipped or fallen down without any vehicle being involved is excluded, the number of seriously injured was around 4700. The result of the study has been included in the road safety goal for Sweden with the aim to have 25% less seriously injured people in 2020 than the average for the years 2006–2008. The results also showed that 91% of the seriously injured were transported by car, bike or by foot. The relatively high proportion of pedestrian fall accidents happening within the transport system irrespective of whether a vehicle was moving or not raises the question whether these types of accidents should be included in the reporting of formal road traffic accidents.     

Explicit or implicit situation awareness? Measuring the situation awareness of train traffic controllers

Previous research on situation awareness (SA) predominantly focused on its explicit, reasoned, conscious features rather than on the implicit, intuitive, unconscious aspects that are often identified with expert operators. This research investigated implicit levels of SA of train traffic controllers (TTCs) in order to contribute to the body of knowledge on rail human factors research and SA. A novel approach was used to uncover levels of implicit SA through a set of three analyses: (1) fairly low SAGAT values with correlations between SAGAT scores and multiple performance indicators; (2) negative correlations between work experience and SAGAT scores; and (3) structurally lower level-1 SA (perception) scores in comparison to level-2 SA (comprehension) scores in accordance with Endsley’s three-level model. Two studies were conducted: A pilot study – which focused on SA measurements with TTCs in a monitoring mode (N = 9) – and the main study, which involved TTCs from another control center (N = 20) and three different disrupted conditions. In the pilot study, SA was measured through the situation-awareness global assessment technique (SAGAT), perceived SA and observed SA, and performance was measured through punctuality and unplanned stops of trains before red signals. In the main study, SA was measured through SAGAT, and perceived SA and multiple performance indicators, such as arrival and departure punctuality and platform consistency, were assessed. In both studies, the set of three analyses showed consistent and persistent indications of the presence of implicit SA. Endsley’s three-level model and related SAGAT method can be constrained by the presence of these intuitive, unconscious processes and inconsistent findings on correlations between SAGAT scores and performance. These findings provide insights into the SA of TTCs in the Netherlands and can support the development of training programs and/or the design of a new traffic management system.     

Blaming a Few Bad Apples to Save a Threatened Barrel: The System‐Justifying Function of Conspiracy Theories

This research demonstrates that conspiracy theories—often represented as subversive alternatives to establishment narratives—may bolster, rather than undermine, support for the social status quo when its legitimacy is under threat. A pilot study (N = 98) found a positive relationship between conspiracy belief and satisfaction with the status quo. In Study 1 (N = 120), threatening (vs. affirming) the status quo in British society caused participants to endorse conspiracy theories. In Study 2 (N = 159), exposure to conspiracy theories increased satisfaction with the British social system after this had been experimentally threatened. In Study 3 (N = 109), this effect was mediated by the tendency for participants exposed (vs. not exposed) to conspiracy theories to attribute societal problems relatively more strongly to small groups of people rather than systemic causes. By blaming tragedies, disasters, and social problems on the actions of a malign few, conspiracy theories can divert attention from the inherent limitations of social systems.
