Is gaze behaviour in a laboratory context similar to that in real-life? A study in bicyclists

Numerous laboratory-based studies recorded eye movements in participants with varying expertise when watching video projections in the lab. Although research in the lab offers the advantage of internal validity, reliability and ethical considerations, ecological validity is often questionable. Therefore the current study compared visual search in 13 adult cyclists, when cycling a real bicycle path and while watching a film clip of the same road. Dwell time towards five Areas of Interest (AOIs) is analysed. Dwell time (%) in the lab and real-life was comparable only for the low quality bicycle path. Both in real-life and the lab, gaze is predominantly driven towards the road. Since gaze behaviour in the lab and real-life tends to be comparable with increasing task-complexity (road quality), it is concluded that under certain task constraints laboratory experiments making use of video clips might provide valuable information regarding gaze behaviour in real-life.     

Visual search for emotional expressions: Effect of stimulus set on anger and happiness superiority

Prior reports of preferential detection of emotional expressions in visual search have yielded inconsistent results, even for face stimuli that avoid obvious expression-related perceptual confounds. The current study investigated inconsistent reports of anger and happiness superiority effects using face stimuli drawn from the same database. Experiment 1 excluded procedural differences as a potential factor, replicating a happiness superiority effect in a procedure that previously yielded an anger superiority effect. Experiments 2a and 2b confirmed that image colour or poser gender did not account for prior inconsistent findings. Experiments 3a and 3b identified stimulus set as the critical variable, revealing happiness or anger superiority effects for two partially overlapping sets of face stimuli. The current results highlight the critical role of stimulus selection for the observation of happiness or anger superiority effects in visual search even for face stimuli that avoid obvious expression related perceptual confounds and are drawn from a single database.     

Probabilistic Inferences Under Emotional Stress: How Arousal Affects Decision Processes

Many models of decision making neglect emotional states that could affect individuals' cognitive processes. The present work explores the effect of emotional stress on people's cognitive processes when making probabilistic inferences. Two contrasting hypotheses are tested against one another: the uncertainty‐reduction and attention‐narrowing hypotheses of how emotional stress affects decision making. In the experimental study, emotional stress was induced through the use of highly aversive pictures immediately before each decision. Emotional state was assessed by both subjective (state anxiety, arousal, and pleasantness ratings) and objective (skin conductance) measures. The results show that emotional stress impacts decision making; in particular, emotionally aroused participants seem to have focused on the most important information and selected simpler decision strategies relative to participants in a control condition. The results are in line with the attention‐narrowing hypothesis and suggest that emotional stress can impact decision making through limited predecisional information search and the selection of simpler decision strategies.

The illusionist and the folk: On the role of conscious planning in intentionality judgments

Illusionism is a prominent hypothesis about action control, according to which acts that we consider voluntary are nevertheless caused by unconscious brain events, and thus our subjective experience of consciously willing them is ultimately illusory. Illusionism can be understood as either an ontological thesis or a phenomenological claim, but both versions are vulnerable to a line of attack based on the role of long-term planning (distal intentions) in action control. According to this objection, the evidence upon which illusionism rests is confined to short-term (proximal) intentions, so it is not sufficient to justify broader conclusions on the causal inefficacy of conscious will. In this essay we reconstruct the logic of this objection against illusionism, clarify why surveying folk intuitions on conscious distal intentions is essential to the debate, and present a study in which the role of conscious planning in intentionality judgment is clearly revealed. We also present other relevant findings, such as a gender effect on intentionality attributions, a moral influence on responsibility judgments, and confirmation of mechanistic incompatibilism.     

不同背景下不同频率闪烁的突显工效研究

本实验对黑、白背景下高频、中频、低频三种闪烁的突显工效进行了比较研究。实验结果表明：闪烁作为突显类型可以提高视觉搜索的绩效,而且,在闪烁的频率较高时（２７Ｈｚ以上）,这种闪烁的突显工效更为明显。视觉材料的呈现背景对闪烁突显视觉搜索绩效没有明显的影响,但在白背景下采用闪烁效果较好。     

All on the Same Side: Reflections on the Dialogue Between Science and Religion

The 'war' between religion and science is winding down, creating new opportunities for fruitful dialogue. The foundations of indirect religion-science dialogue, where the perspectives of the two disciplines illuminate some third subject, are not well established. A detailed comparison of the Roman Catholic bishops' dialogues and a similar program within the American Association for the Advancement of Science illustrates the variety in formalscience-religion interactions and reveals much about the promise, achievements, and limitations of different approaches. Success depends in large part on controlling the diversity of the dialogue group, choosing topics carefully, and adopting positive and cooperative attitudes.     

生命意义的内涵、测量及功能

研究者通常用目的和含义来定义生命意义,或者把它定义为多维度的结构。认知、动机和情感是被提及最多的生命意义的组成维度。动机和认知维度得到了较多研究者的认可,而情感维度存在较大争议。生命意义是幸福不可或缺的元素,它能够影响许多与幸福有关的变量。目前的研究对生命意义的动机维度(生命意义寻求)及如何获得和提高生命意义研究较少,今后的研究可针对这两方面开展。     

Effets du soutien organisationnel perçu et des caractéristiques de l’emploi sur l’anxiété au travail et l’épuisement professionnel : le rôle médiateur de la satisfaction des besoins psychologiques

Based on organizational support theory, job characteristics model, and self-determination theory, we examined the mechanisms that underlie the relations between organizational factors and ill-being. Specifically, the main purpose of the present study was to demonstrate the mediating role of the psychological needs for autonomy (i.e., the need for individuals to feel volitional and responsible for their own behavior), competence (i.e., the need for individuals to interact effectively with their environment), and relatedness (i.e., the need for individuals to feel connected and accepted by others), in the relationships of perceived organizational support (i.e., the degree to which employees believe that their organization values their contributions and cares about their well-being) and three motivational job characteristics (i.e., task identity, task significance, and work scheduling autonomy) to job anxiety and burnout. This is the first research, to the best of our knowledge, to test for the joint effects of perceived organizational support and motivational job characteristics on job anxiety and burnout through psychological need satisfaction. Four hundred and fifty-seven employees (216 men and 241 women) from different sectors (i.e., industry, trade, crafts) took part in the study. Fifty-seven participants worked in companies with less than 10 employees, 105 in companies with 11–49 employees, 138 in companies with 50–249 employees, 33 in companies with 250–499 employees, and 124 in companies with more than 500 employees. The hypothesized model was tested with structural equation modeling analyses. Results provided support for our hypotheses and revealed that all hypothesized paths were significant. Specifically, our results showed that perceived organizational support and job characteristics were positively related to psychological need satisfaction. In addition, satisfaction of these psychological needs was negatively associated with job anxiety and burnout. Therefore, feelings of autonomy, competence, and relatedness play a central role in the development or reduction of well- and ill-being at work. These results are consistent with previous research in the work context, which has shown that social factors (e.g., autonomy-supportive behaviors) have significant effects on workplace mental health through their influence on psychological need satisfaction. Practical and research implications as well as suggestions for future research are discussed.     

Social cohesion predicts COVID-19 vaccination intentions and uptake

COVID-19 vaccination is widely regarded as an individual decision, resting upon individual characteristics and demographic factors. In this research, we provide evidence that psychological group membership, and more precisely, social cohesion—a multidimensional concept that encompasses one's sense of connectedness to, and interrelations within, a group—can help us understand COVID-19 vaccination intentions (Study 1) and uptake (Study 2). Study 1 is a repeated-measures study with a representative sample of 3026 Australians. We found evidence that social cohesion can be conceptualised as a multidimensional structure; moreover, social cohesion at Wave 1 (early in the COVID-19) predicted greater vaccination intention and lower perceived risk of vaccination at Wave 2 (4 months later). In Study 2 (a cross-sectional study, N = 499), the multidimensional structure of social cohesion was associated with greater uptake of vaccine doses (in addition to willingness to receive further doses and perceived risk of the vaccine). These relations were found after controlling for a series of demographic (i.e., sex, age, income), health-related factors (i.e., subjective health; perceived risk; having been diagnosed with COVID-19), and individual differences (political orientation, social dominance orientation, individualism). These results demonstrate the need to go beyond individual factors when it comes to behaviours that protect groups, and particularly when examining COVID-19 vaccination—one of the most important ways of slowing the spread of the virus.
