Visual perception of complex shape-transforming processes

Morphogenesis—or the origin of complex natural form—has long fascinated researchers from practically every branch of science. However, we know practically nothing about how we perceive and understand such processes. Here, we measured how observers visually infer shape-transforming processes. Participants viewed pairs of objects (‘before’ and ‘after’ a transformation) and identified points that corresponded across the transformation. This allowed us to map out in spatial detail how perceived shape and space were affected by the transformations. Participants’ responses were strikingly accurate and mutually consistent for a wide range of non-rigid transformations including complex growth-like processes. A zero-free-parameter model based on matching and interpolating/extrapolating the positions of high-salience contour features predicts the data surprisingly well, suggesting observers infer spatial correspondences relative to key landmarks. Together, our findings reveal the operation of specific perceptual organization processes that make us remarkably adept at identifying correspondences across complex shape-transforming processes by using salient object features. We suggest that these abilities, which allow us to parse and interpret the causally significant features of shapes, are invaluable for many tasks that involve ‘making sense’ of shape.     

Terror in time: extending culturomics to address basic terror management mechanisms

Building on Google's efforts to scan millions of books, this article introduces methodology using a database of annual word frequencies of the 40,000 most frequently occurring words in the American literature between 1800 and 2009. The current paper uses this methodology to replicate and identify terror management processes in historical context. Variation in frequencies of word usage of constructs relevant to terror management theory (e.g. death, worldview, self-esteem, relationships) are investigated over a time period of 209 years. Study 1 corroborated previous TMT findings and demonstrated that word use of constructs related to death and of constructs related to patriotism and romantic relationships significantly co-vary over time. Study 2 showed that the use of the word “death” most strongly co-varies over time with the use of medical constructs, but also co-varies with the use of constructs related to violence, relationships, religion, positive sentiment, and negative sentiment. Study 3 found that a change in the use of death related words is associated with an increase in the use of fear related words, but not in anxiety related words. Results indicate that the described methodology generates valuable insights regarding terror management theory and provide new perspectives for theoretical advances.     

The effect of decision timing on the willingness to costly reward cooperation and punish noncooperation: Sanctioning the past,the present,or the future

Numerous studies have demonstrated that sanctions can promote cooperation. However, it is important to know not only that sanctions can work but also under what conditions people are actually willing to sanction cooperation positively (i.e., reward) or noncooperation negatively (i.e., punish). In this article, we demonstrate that people use sanctions less often and sanction more mildly when they decide about sanctioning before (instead of after) the occurrence of others' (non)cooperation (Experiments 1 and 2), regardless of whether they decide directly afterwards or after a time delay (Experiment 2). Moreover, we reveal that beforehand (as compared with afterwards) people have not yet formed clear sanctioning preferences (Experiment 3). These findings corroborate our reasoning that the decision environment beforehand induces nonconsequential reasoning and thereby hampers people's willingness to sanction. We discuss the theoretical, methodological, and practical implications of our work.     

Too good to be true? Psychological responses to uncommon options in risk–reward environments

Risks and rewards, or payoffs and probabilities, are inversely related in many choice environments. We investigated people's psychological responses to uncommon combinations of risk and reward that deviate from learned regularities (e.g., options that offer a high payoff with an unusually high probability) as they evaluated risky options. In two experiments (N = 183), participants first priced monetary gambles drawn from environments in which risks and rewards were negatively correlated, positively correlated, or uncorrelated. In later trials, they evaluated gambles with uncommon combinations of risk and reward—that is, options that deviated from the respective environment's risk–reward structure. Pricing, response times, and (in Experiment 2) pupil dilation were recorded. In both experiments, participants took more time when responding to uncommon compared to foreseeable options or when the same options were presented in an uncorrelated risk–reward environment. This result was most pronounced when the uncommon gambles offered higher expected values compared to the other gambles in the set. Moreover, these uncommon, high‐value options were associated with an increase in pupil size. These results suggest that people's evaluations of risky options are based not only on the options' payoffs and probabilities but also on the extent to which they fit the risk–reward structure of the environment.     

Children and Consumer Behavior: Insights,Questions, and New Frontiers

We thank Deborah John, Lan Chaplin, and Daphna Oyserman for their insightful and generous responses. Each commentary seriously takes up the challenge we set forth at the end of our target article—how to link the research on children's concepts of object value to broader issues involving persuasion, including social influences on choices, behaviors, and values. In doing so, they build on our original paper in rich and exciting ways.     

Still People of the Book A History of the Church in 100 Objects,Mike Aquilina and Grace Aquilina,Ave Maria, 2017 (ISBN 978‐1‐59471‐750‐5), 448 pp., pb $24.95

The recent turn to ‘material religion’ in the academic study of religion offers a new opportunity for scholars and practitioners to take the embodied, devotional lives of adherents seriously. In their new book, A History of the Church in 100 Objects, Mike and Grace Aquilina might be productively read as responding to this new openness on the part of scholars by presenting Roman Catholic history as told through those objects that have guided the practices of the faithful. Despite their protestations to the contrary, however, the story that they tell is still mostly determined by the authoritative interpretation of sacred texts instead of ordinary interactions with sacred objects.     

奖赏对海洛因成瘾者执行功能的影响机制

一些研究发现海洛因成瘾者奖赏失调表现为:对海洛因相关线索的注意偏向、渴求感增加,对金钱奖赏表现出"即时收益优先"的高风险决策模式和对长时收益的敏感性降低。另一些研究发现海洛因成瘾者的执行功能存在障碍。奖赏失调和执行功能障碍在成瘾物质使用的维持和复吸中起着重要作用。双重竞争模型认为奖赏和执行功能的交互作用决定着行为的结果,但是奖赏对海洛因成瘾者执行功能的影响机制还不清楚。因此,拟使用事件相关电位技术来考察海洛因相关线索和金钱奖赏对不同戒断期成瘾者执行功能的影响机制,短期(1~3个月)、长期(18个月以上)海洛因戒断者和健康对照组被比较。这不仅有助于构建完善的成瘾理论体系,还有助于确定临床戒断后复吸的风险因素和不同戒断期的治疗目标。     

Religious studies as a modern academic discipline in Korea

This article offers a historical and institutional overview of the discipline of religious studies in Korea. It first reviews four early sources of comparative studies: work by Christian missionaries; by Japanese scholars during the period of colonization by that nation; by nationalist Korean scholars who reacted against colonization; and by Korean Christian theologians. The founding of the Korean Association for the History of Religions (KAHR) in 1969 was a key point in the professionalization of the discipline. The field became more firmly established in the late 1980s and early 1990s and has diversified in recent years with a new generation of often foreign-trained scholars. The article ends with a brief discussion of potential contributions that the discipline could make to current debates of national significance.     

The mobile frontiers of Piaget’s psychology. From academic tourism to interdisciplinary collaboration / Las fronteras móviles de la psicología de Piaget. Del turismo académico a la colaboración interdisciplinaria

Jean Piaget’s (1896–1980) interdisciplinarity was related to his psychology in several ways. First, he was a simple tourist of other fields: an interested outsider. But as he became increasingly involved in the professionalization of the discipline, he moved through different contexts that constrained the possibilities for successful action in new and different ways. To make these clear, we adopt a little-known aspect of his later epistemological framework: the open hierarchy of levels. This then affords new perspectives of his life, his work, his theory and his location in the history of both Swiss psychology and French psychology. It also outlines his reasoning regarding the necessity of a disciplined approach to interdisciplinary collaboration, institutionalized in the founding of his International Centre for Genetic Epistemology. We therefore come not only to a fuller understanding of how Piaget thought scientific knowledge develops, but also of how the boundaries of scientific disciplines are pushed back.
