Observers viewed the optical flow field of a rotating quadric surface patch and were required to match its perceived structure by adjusting the shape of a stereoscopically presented surface. In Experiment 1, the flow fields included rigid object rotations and constant flow fields with patterns of image acceleration that had no possible rigid interpretation. In performing their matches, observers had independent control of two parameters that determined the surface shape. One of these, called the shape characteristic, is defined as the ratio of the two principle curvatures and is independent of object size. The other, called curvedness, is defined as the sum of the squared principle curvatures and depends on the size of the object. Adjustments of shape characteristic were almost perfectly accurate for both motion conditions. Adjustments of curvedness, on the other hand, were systematically overestimated and were not highly correlated with the simulated curvedness of the depicted surface patch. In Experiment 2, the same flow fields were masked with a global pattern of curl, divergence, or shear, which disrupted the first-order spatial derivatives of the image velocity field, while leaving the second-order spatial derivatives invariant. The addition of these masks had only negligible effects on observers’ performance. These findings suggest that observers’ judgments of three-dimensional surface shape from motion are primarily determined by the second-order spatial derivatives of the instantaneous field of image displacements. 相似文献

Janine de Peyer has done pioneering work in (re)opening the exploration of uncanny phenomena within the context of the psychoanalytic encounter. In this response her achievement is celebrated and placed against the backdrop of recent advances in Jungian or Analytical Psychology. In particular the application of complexity theory to synchronistic phenomena is suggested as a valuable means of assess these experiences. The use of field theory to help capture the distributed, nonlocal aspect of the interactive field active in such material is traced back to 19th-century physics and William James’s introduction of this concept into psychology. In an attempt to take another step forward, an ecological approach to these phenomena is suggested. 相似文献

This article argues that Pope Francis's invocations of wonder can speak to and at times challenge Lisa Sideris's recent contributions to the interdisciplinary discussion of wonder, science, and religion. Although the importance of wonder to Pope Francis's 2015 environmental encyclical Laudato si’ is acknowledged, it has not been widely recognized that wonder is implicated in and forms connections between multiple concepts and postures acknowledged as defining marks of Francis's papacy: coming out of oneself, encountering others, going to the margins; aversion to doctrinal rigidity; compassion, mercy, tenderness, and humility; to name a few. These defining concepts and stances resonate strongly with certain views on wonder, ethics, and ecology recently articulated by Lisa Sideris. In Francis, however, one finds a more affirming treatment of science‐based wonder and a response to Sideris's criticism of theistic wonder. 相似文献

When couples decide to share their lives, they must also decide how to pool their finances. In this article, we ask: Does the type of bank account from which one spends (joint vs. separate) affect the type of products one chooses to buy (utilitarian vs. hedonic)? Real‐world evidence from analyzing bank transaction records (study 5), as well as data collected from experiments in the field (studies 1 and 2) and lab (studies 3 and 4), converge to support the hypothesis that couple members who spend from a joint bank account are more likely to choose utilitarian (vs. hedonic) products, than those who spend from a separate bank account. We find that these different spending patterns are driven by an increased need to justify spending to one's partner that is experienced when money is pooled together. If a hedonic product becomes easier to justify (study 4), the effect of account type on spending patterns disappears. These findings have important theoretical and practical implications for better understanding financial decision‐making within romantic couples. 相似文献
