材料情绪性对条件推理影响的眼动研究

以大学生为被试,采用不同情绪效价的条件命题作为实验材料,运用眼动仪器记录被试进行条件推理的过程和结果,探讨了材料情绪性对条件推理的影响状况.实验采用3(材料情绪性:正性情绪、负性情绪、中性情绪)×4(推理形式:MP、DA、AC、MT)的重复测量实验设计.研究结果发现,正性和负性情绪材料的条件推理成绩显著地低于中性情绪材料,结果支持抑制假说.     

不确定性决策违背“确定事件原则”的心理机制再探

不确定性决策违背＂确定事件原则＂的心理机制再探从决策理由切入,在现实情境中考察了违背确定事件原则（sure-thing principle）的心理机制,检验了基于理由（reason-based）的假设。研究结果表明,违背确定事件原则的被试在不确定条件下知觉到的理由冲突程度显著高于遵循确定事件原则的被试在不确定条件下知觉到的理由冲突程度;违背确定事件原则的被试在不确定条件下知觉到的理由清晰程度显著低于其在两种确定条件下知觉到的理由清晰程度,而遵循确定事件原则的被试在不确定条件下知觉到的理由清晰程度则介于其在两种确定条件下知觉到的理由清晰程度之间。研究结果支持了基于理由的假设。     

Active coping with stress suppresses glucose metabolism in the rat hypothalamus

We used 18F-fluorodeoxyglucose small-animal positron-emission tomography to determine whether different styles of coping with stress are associated with different patterns of neuronal activity in the hypothalamus. Adult rats were subjected to immobilization (IMO)-stress or to a non-immobilized condition for 30 min, in random order on separate days, each of which was followed by brain-scanning. Some rats in the immobilized condition were allowed to actively cope with the stress by chewing a wooden stick during IMO, while the other immobilized rats were given nothing to chew on. Voxel-based statistical analysis of the brain imaging data shows that chewing counteracted the stress-induced increased glucose uptake in the hypothalamus to the level of the non-immobilized condition. Region-of-interest analysis of the glucose uptake values further showed that chewing significantly suppressed stress-induced increased glucose uptake in the paraventricular hypothalamic nucleus and the anterior hypothalamic area but not in the lateral hypothalamus. Together with the finding that the mean plasma corticosterone concentration at the termination of the IMO was also significantly suppressed when rats had an opportunity to chew a wooden stick, our results showed that active coping by chewing inhibited the activation of the hypothalamic-pituitary-adrenal axis to reduce the endocrine stress response.     

Bioethics committee in the university teaching hospital in Bordeaux

Set up in 2011, the ethics committee at the teaching hospital in Bordeaux, although it is now obsolete in its organisation because of the "standardisation" in early 2012 of regional ethics groups, was nevertheless an original structure which deserves to be analysed for several reasons. First of all, why have a hospital ethics committee? Then, to do what? Finally, it is interesting to give a few indications about the working of this committee.     

The influence of lay theories of Feng Shui on consumers' peace of mind: The role of regulatory fit

With its history dating back five millennia, the art of creating harmonious surroundings – commonly referred to as Feng Shui – has become deeply rooted in Chinese culture. Yet despite its significant effect on people's daily lives, a dearth of research is available on how Feng Shui influences consumers' decisions. This study investigates the influence of Feng Shui on customers' attitude based on their regulatory focus, providing suggestions for business opportunities. Three studies examine whether Feng Shui's goals influence participants' decisions and feelings of appropriateness. Study 1 demonstrated that the fit between Feng Shui's suggestions and consumers' regulatory focus impacted decision making. Participants were more likely to adopt the Feng Shui practitioner's suggestions of a goal compatible with the consumers' regulatory focus. Study 2 provided evidence that a regulatory focus also impacts participants' peace of mind. Study 3 tested whether the value experienced from regulatory fit is reflected in the price. Specifically, promotion‐oriented individuals feel more accepting of promotion‐focused Feng Shui that is consistent with an approach goal while prevention‐oriented individuals are more persuaded by prevention‐focused Feng Shui that is consistent with an avoidance goal. When the Feng Shui appeal is compatible with the self‐regulatory focus, individuals demonstrate a greater feeling of appropriateness and produce a higher level of peace of mind.     

The nature and consequences of topic avoidance in Chinese and Taiwanese close relationships

Two studies examined topic avoidance in Chinese and Taiwanese opposite‐sex friendships and romantic relationships. Five areas of topic avoidance emerged through analytic induction and cluster analysis: negative appraisal, relational issues, sexual issues, politics, and personal experience. Partner protection, negative relational impact, and self inefficacy emerged as the most common reasons for avoidance. Results revealed that friends, relative to romantic partners, engaged in higher levels of topic avoidance. Taiwanese participants, moreover, avoided discussing politics to a greater extent than did mainland Chinese participants. Lacking closeness was the main reason behind avoidance of political discussion. Topic avoidance was also linked to relationship quality, as relational satisfaction negatively predicted relational issue avoidance and topic avoidance breadth (i.e. the number of topics regularly avoided in the relationship). The authors explain these and other findings based on Chinese cultural codes and historically‐embedded concepts that shape interpersonal interaction.     

Sweeping dishonesty under the rug: how unethical actions lead to forgetting of moral rules

Dishonest behavior can have various psychological outcomes. We examine whether one consequence could be the forgetting of moral rules. In 4 experiments, participants were given the opportunity to behave dishonestly, and thus earn undeserved money, by over-reporting their performance on an ability-based task. Before the task, they were exposed to moral rules (i.e., an honor code). Those who cheated were more likely to forget the moral rules after behaving dishonestly, even though they were equally likely to remember morally irrelevant information (Experiment 1). Furthermore, people showed moral forgetting only after cheating could be enacted but not before cheating (Experiment 2), despite monetary incentives to recall the rules accurately (Experiment 3). Finally, moral forgetting appears to result from decreased access to moral rules after cheating (Experiment 4).     

Visual assessment of camouflaged targets with different background similarities

The study investigated the effectiveness of different camouflage designs using a computational image quality index. Camouflaged human targets were presented on a natural landscape and the targets were designed to be similar to the landscape background with different levels of background similarity as estimated by the image index. The targets were presented in front of the observer (central 0 degrees) or at different angles in the left (-7 degrees, -14 degrees, -21 degrees) or right (+7 degrees, +14 degrees, +21 degrees) visual fields. The observer had to detect the target using peripheral vision if the target appeared in the left and right visual fields. The camouflage effectiveness was assessed by detection hit rates, detection times, and subjective ratings on detection confidence and task difficulty. The study showed that the psychophysical measures correlated well with the image similarity index, suggesting a potentially more efficient camouflage effectiveness assessment tool if the relationship between the psychophysical results and the index can be quantified in the future.
