Consolidation,wider reflection,and policy: Response to ‘Super‐recognisers: From the lab to the world and back again’

Here, David Robertson and Markus Bindemann respond to a recent BJP Target Article on ‘super‐recognisers’ (SRs). They outline the need to consider human factors that could influence SR performance after selection and the need for a co‐ordinated effort to ensure best practice in the implementation of SRs in applied contexts.     

Clinical Ethicists Awakened: Addressing Two Generations of Clinical Ethics Issues Involving Undocumented Patients

Because the United States has failed to provide a pathway to citizenship for its long-term undocumented population, clinical ethicists have more than 20 years of addressing issues that arise in caring for this population. I illustrate that these challenges fall into two sets of issues. First-generation issues involve finding ethical ways to treat and discharge patients who are uninsured and ineligible for safety-net resources. More recently, ethicists have been invited to help address second-generation issues that involve facilitating the presentation for care of undocumented patients. In the current environment of widespread fear of deportation in the immigrant community, ethicists are working with health care providers to address patient concerns that prevent them from seeking care. I illustrate that in both generations of issues, values implicit within health care, namely, caring, efficiency, and promotion of public health, guide the strategies that are acceptable and recommended.     

政策满意度、教师支持对免费师范生职业认同的作用:从教动机的中介效应

本研究以733名免费师范生为被试,采用问卷测量法,考察师范生对免费教育政策的满意度、所感知到的教师支持,及其师范生从教动机与职业认同的特点及其相互之间的关系,并检验了从教动机在政策满意度、教师支持与职业认同之间的中介效应。结果表明：（1）师范生在政策满意度、从教动机上存在年级差异,在职业认同上存在年级和性别差异。（2）政策满意度、教师支持、从教动机与职业认同两两之间均呈显著正相关。（3）政策满意度与教师支持对职业认同的直接效应显著,从教动机在政策满意度与职业认同之间、教师支持与职业认同之间均起部分中介作用,其中从教动机对政策满意度的中介效应显著高于对教师支持的中介效应。本研究围绕这些结果进行了讨论,并提出了相应的建议和对策。     

God's Country?

Abstract : Religion has always been a major force in U.S. politics, but the recent surge in the number and the power of evangelicals is recasting the country's political scene—with dramatic implications for foreign policy. This should not be cause for panic: evangelicals are passionately devoted to justice and improving the world, and eager to reach out across sectarian lines.     

All in this together? Group representations and policy support

The present research explored the relationship between how Canadians perceived the quality of intergroup contact with Americans and their support for different antiterrorism policies, considering the potential mediating role of intergroup representations specified in the Common Ingroup Identity Model. Canadian students (n = 360) completed questionnaires that assessed their perceptions of the quality of intergroup contact with Americans, group representations, and reactions to various policies tied to the war against terror. Specifically, we tested a model of how perceptions of the quality of intergroup contact, along the dimensions specified by the Contact Hypothesis, predict different representations of the two groups (Canadians and Americans), and then how these different representations predict reactions to antiterrorist policies. Structural equation modeling analysis supported the predictions, revealing the pivotal role of group representations for policy views.     

Healthy happiness: effects of happiness on physical health and the consequences for preventive health care

Is happiness good for your health? This common notion is tested in a synthetic analysis of 30 follow-up studies on happiness and longevity. It appears that happiness does not predict longevity in sick populations, but that it does predict longevity among healthy populations So, happiness does not cure illness but it does protect against becoming ill. The effect of happiness on longevity in healthy populations is remarkably strong. The size of the effect is comparable to that of smoking or not.If so, public health can also be promoted by policies that aim at greater happiness of a greater number. That can be done by strengthening individual life-abilities and by improving the livability of the social environment. Some policies are proposed. Both ways of promoting health through happiness require more research on conditions for happiness.     

Is your choice my choice? The owners’ effect on pet dogs’ (Canis lupus familiaris) performance in a food choice task

This study investigates the influence of owners on their dogs’ performance in a food choice task using either different or equal quantities of food. Fifty-four pet dogs were tested in three different conditions. In Condition 1 we evaluated their ability to choose between a large and small amount of food (quantity discrimination task). In Condition 2 dogs were again presented with a choice between the large and small food quantity, but only after having witnessed their owner favouring the small quantity. In Condition 3 dogs were given a choice between two equally small quantities of food having witnessed their owner favouring either one or the other. A strong effect of the owner on the dogs’ performance was observed. In Condition 1 dogs as a group chose significantly more often the large food quantity, thus showing their ability to solve the quantity discrimination task. After observing their owner expressing a preference for the small food quantity they chose the large quantity of food significantly less than in the independent choice situation. The tendency to conform to the owner’s choice was higher when the dogs had to choose between equally small quantities of food (Condition 3) rather than between a large and a small one (Condition 2). These results provide evidence that dogs can be influenced by their owners even when their indications are clearly in contrast with direct perceptual information, thus leading dogs to ultimately make counterproductive choices.     

Foraging and associative learning of visual signals in a parasitic wasp

To cope with environmental variability, animals should gather and use information to reduce uncertainty. In insect parasitoids, associative learning has been widely documented in the context of host foraging. However, despite its potential adaptive value, the insect food searching strategy and cues used to search are poorly understood. In this study, we examined the ability of hymenopteran Venturia canescens females to associate food to a visual cue. To broaden the scope of our results, experiments were performed with both arrhenotokous (sexual) and thelytokous (asexual) individuals. The wasps showed innate attraction for yellow and orange stimuli when presented versus blue stimuli. When trained to associate a food reward with one of the attractive colours (orange), they significantly moved from a distance towards the colour previously associated with food. The choice of the innately preferred colour (yellow) was not modified by associative learning. In the context of food foraging, this study is the first to show associative learning using visual stimuli in a parasitoid and active choice of this colour. This ability gives new insights concerning potential food sources for V. canescens in the field, since flowers are sugar sources, which emit colour signals.     

Perceived History of Anaphylaxis and Parental Overprotection,Autonomy, Anxiety,and Depression in Food Allergic Young Adults

This study examined autonomy, anxiety, depression, and perceptions of parental behavior in 86 food allergic young adults and 344 healthy young adults between the ages of 18 and 22. Participants completed an online survey measuring self-reported autonomy, anxiety, depression, and perceptions of parental behavior. Results indicated that, as a group, food allergic young adults did not differ from healthy peers. However, food allergic young adults who reported having experienced an anaphylactic reaction described their disease as more severe, reported more worry about their disease, and rated their parents as more overprotective than food allergic young adults who reported never having experienced anaphylaxis. The experience of anaphylaxis may be a reliable indicator of food allergic individuals who are at risk for psychological distress. A portion of this research was presented at the National Conference on Child Health Psychology in Miami, Fl in April, 2008.
