Understanding conditional promises and threats

Conditional promises and threats are speech acts that are used to manipulate other people's behaviour. Studies on human reasoning typically use propositional logic to analyse what people infer from such inducements. While this approach is sufficient to uncover conceptual features of inducements, it fails to explain them. To overcome this limitation, we propose a multilevel analysis integrating motivational, linguistic, deontic, behavioural, and emotional aspects. Commonalities and differences between conditional promises and threats on various levels were examined in two experiments. The first shows that both types of inducements are understood as being complementary on the linguistic level, but not reversible, due to the specific temporal order of their actions. In addition, it gives a first assessment of emotional reactions. The second experiment investigated the novel question of whether complementary promises and threats, despite semantic differences, both imply an obligation to cooperate on the deontic level. The data corroborate this hypothesis, and they support various appraisal-theoretical assumptions on the elicitation of emotions. They also reveal that content affects not only the attribution of emotions, but also the deontic interpretation.     

学经济学降低人际信任?经济类专业学习对大学生人际信任的影响

本研究试图证明,经济类专业学习会降低大学生的人际信任.研究者测量了某财经类重点高校经济类和非经济类专业的大一和大三共290名本科生的人际信任水平,发现专业类型和年级存在显著交互作用,大一的经济类学生和非经济类学生在人际信任水平上无显著差异,而大三的经济类学生在人际信任水平上却显著低于非经济类专业.这说明经济类专业学习时间的增加可能是学生人际信任水平下降的原因,可能的机制是,学习经济学会使个体逐渐接受和认同“理性人假设”所包含的人性观点,认为他人的行为都是基于自私和功利的目的.     

Kinetic analysis of oxygen dynamics under a variable work rate

Measurements of oxygen uptake are central to methods for the assessment of physical fitness and endurance capabilities in athletes. Two important parameters extracted from such data of incremental exercise tests are the maximal oxygen uptake and the critical power. A commonly accepted model of the dynamics of oxygen uptake during exercise at a constant work rate comprises a constant baseline oxygen uptake, an exponential fast component, and another exponential slow component for heavy and severe work rates. We have generalized this model to variable load protocols with differential equations that naturally correspond to the standard model for a constant work rate. This provides the means for predicting the oxygen uptake response to variable load profiles including phases of recovery. The model parameters have been fitted for individual subjects from a cycle ergometer test, including the maximal oxygen uptake and critical power. The model predictions have been validated by data collected in separate tests. Our findings indicate that the oxygen kinetics for a variable exercise load can be predicted using the generalized mathematical standard model. Such models can be applied in the field where the constant work rate assumption generally is not valid.     

A Markov Chain Analysis of Emotional Exchange in Voice‐to‐Voice Communication: Testing for the Mimicry Hypothesis of Emotional Contagion

Mimicry is a central plank of the emotional contagion theory; however, it was only tested with facial and postural emotional stimuli. This study explores the existence of mimicry in voice‐to‐voice communication by analyzing 8,747 sequences of emotional displays between customers and employees in a call‐center context. We listened live to 967 telephone interactions, registered the sequences of emotional displays, and analyzed them with a Markov chain. We also explored other propositions of emotional contagion theory that were yet to be tested in vocal contexts. Results supported that mimicry is significantly present at all levels. Our findings fill an important gap in the emotional contagion theory; have practical implications regarding voice‐to‐voice interactions; and open doors for future vocal mimicry research.     

The "sense of agency" and its underlying cognitive and neural mechanisms

The sense of agency is a central aspect of human self-consciousness and refers to the experience of oneself as the agent of one’s own actions. Several different cognitive theories on the sense of agency have been proposed implying divergent empirical approaches and results, especially with respect to neural correlates. A multifactorial and multilevel model of the sense of agency may provide the most constructive framework for integrating divergent theories and findings, meeting the complex nature of this intriguing phenomenon.     

It’s in your nature: a pluralistic folk psychology

I suggest a pluralistic account of folk psychology according to which not all predictions or explanations rely on the attribution of mental states, and not all intentional actions are explained by mental states. This view of folk psychology is supported by research in developmental and social psychology. It is well known that people use personality traits to predict behavior. I argue that trait attribution is not shorthand for mental state attributions, since traits are not identical to beliefs or desires, and an understanding of belief or desire is not necessary for using trait attributions. In addition, we sometimes predict and explain behavior through appeal to personality traits that the target wouldn’t endorse, and so could not serve as the target’s reasons. I conclude by suggesting that our folk psychology includes the notion that some behavior is explained by personality traits—who the person is—rather than by beliefs and desires—what the person thinks. Consequences of this view for the debate between simulation theory and theory theory, as well as the debate on chimpanzee theory of mind are discussed.     

Evoked culture, ritualization and religious rituals

This study presents an attempt to integrate two theories about ritual: the theory that McCauley and Lawson developed in Bringing Ritual to Mind; Psychological Foundations of Cultural Forms and the theory that Boyer and Liénard presented in a target article in Behavioral and Brain Sciences, ‘Why ritualized behavior in humans? Precaution systems and action-parsing in developmental, pathological and cultural rituals’ and in another article published in the American Anthropologist, ‘Whence collective rituals? A cultural selection model of ritualized behavior’.     

复杂情境下不同角度及思维方式的决策表现差异:决策视角-心理距离的作用

本研究运用2个行为实验探讨了复杂情境下自我决策、为他人决策和预期他人决策在无意识思维方式和有意识思维方式下的决策表现差异。实验1发现复杂情境中无意识思维方式下,自我决策和为他人决策的决策表现显著优于预期他人决策,自我决策和为他人决策表现没有显著差异。实验2发现复杂情境中有意识思维时,在陌生人条件下,为他人决策表现分数显著高于自我决策与预期他人决策,自我决策和预期他人决策表现无显著差异;在朋友条件下,为他人决策和预期他人决策的决策表现显著优于自我决策,为他人决策和预期他人决策表现无显著差异。研究结果支持了本文提出的决策视角-心理距离作用假设(the Perspective-Distance Effect Hypothesis,PDEH)。
