Dynamic Visual Acuity

Forty subjects took part in a one-handed catching task in which the period for which the mechanically projected tennis ball was illuminated in flight was varied systematically. Additionally, they were tested for (a) static visual acuity and (b) dynamic visual acuity, in which angular velocity was varied. As expected, both viewing period in the catching task and angular velocity in the acuity task were significant variables in performance. Correlation and principal-components analyses confirmed the findings of a previous experiment in that the correlated static visual acuity tasks were unrelated to both dynamic visual acuity (even when angular velocity was only 75°/sec) and catching performance. Further, dynamic acuity and catching were related under the majority of the combinations, and most frequently at the highest angular velocity, a fact which suggested that the dynamic element in both tasks is the common factor.     

Self-control and frequency of model presentation: Effects on learning a ballet passé relevé

The purpose of this experiment was to examine the combined effects of self-control and frequency of model presentation on learning a complex motor skill, i.e., ballet passé relevé. Before practice started self-control participants were asked to choose two viewings or six viewings (before practice and then every five trials) and the externally controlled groups were yoked to their self-control counterparts. All participants completed 15 acquisition trials followed by 5 trials for the immediate and 5 trials for the delayed retention tests 48 hours later. Dependent variables included cognitive representation scores, physical reproduction rankings, and balance time. Statistical analyses indicated that under limited physical practice conditions self-control and higher frequency of model presentation facilitated the development of cognitive representation and did not produce further benefits in movement reproductions and balance time. The results were discussed with respect to the social cognitive theory.     

Tasting the divine: the aesthetics of religious emotion in Indian Christianity

The category of rasa (emotional ‘tastes’) in Indian Christian theology and art offers a useful theoretical lens for the academic study of religious emotion. In this article, two Bharata Nā?yam dance ministries provide a case study in the practical applicability of a rasa theology that is emerging within contemporary Indian Christianity. The Christian choreographers have significantly altered the emotions of love and peace in comparison with classical rasa theory and its traditional use in Hindu devotion. Indian Christian artists and theologians have also begun to explore and invent additional aesthetic emotions, giving unique shape to their ‘emotional community.’ Important challenges attend the dance ministries as they are currently configured, yet rasa is a capacious analytical category that can shed new light on Indian Christianity and the study of emotion in religion.     

How does knowledge bring one to the state of immortality in early Upaniṣadic philosophy? A new perspective on the ‘Magical’ way of cognition

ABSTRACT

The Upani?adic philosophers believed that acquiring certain knowledge would lead them toward a state of immortality. Merely by obtaining that knowledge, they thought people could surmount the various causes of death of the natural body. How and why did they develop and maintain this belief? To understand this, this article analyzes the difference between our views as modern humans and those of early Upani?adic philosophers, regarding the concepts of knowledge and death. They seem to have believed that knowing a concept meant actualizing that concept in the real world. Therefore, possessing the concept or knowledge of death guaranteed the actualized occurrence of death. This article argues that early Upani?adic philosophers must have thought that replacing the knowledge of death with the true knowledge of immortality would really make people immortal. In other words, to know that one is immortal truly makes one immortal. I also propose a new method of analyzing ancient thoughts.     

RICOEUR'S PHILOSOPHY AND ITS IMPLICATIONS FOR PSYCHOANALYSIS

In differentiation of early and mature shame, the phenomenological content of shame changes with the development of a stable self-state. In this hypothesis, early shame refers to a person's dependence upon mirroring himself and in being mirrored by an outer object, while mature shame refers to introspection and self-reflection. From a developmental psychological point of view, the connection between self-development and mirroring is expounded. Mirroring is defined as a psychic dialectic process between the inner psychic reality and the outer reality. Early shame is connected to dyadic mirroring, which refers to attachment and empathy. Mature shame is connected to triadic mirroring, which refers to separation and reflection. Early shame emerges from discrepancies between the infant's expectations of a complementary affective response and the mother's response, and is defined as an early marker of differences in the mother/infant unit. It is argued that early shame in smaller ‘doses’ has a regulating function on self-development by maintaining the psychic dialectic process, while in larger ‘doses’, it has a disturbing effect on the self-development, resulting in pathological shame. In the therapeutic process, early shame appears as shame scenarios illustrated in the text by a clinical vignette.     

Categorization of two-dimensional and three-dimensional stimuli by 18-month-old infants

In two experiments, 18-month-old infants’ categorization of 3D replicas and 2D photographs of the same animals and vehicles were compared to explore infants’ flexibility in categorization across different object representations. Using a sequential touching procedure, infants completed one superordinate and two basic-level categorization tasks with 3D replicas, 2D cut out photographs, or 2D images on photo cubes (“2D cubes”). For superordinate sets, 3D replicas elicited longer mean run lengths than 2D cut outs, and 3D replicas elicited equivalent mean run lengths as 2D cubes. For basic-level sets, infants categorized high-contrast animal sets when presented with 3D replicas, but they failed to categorize any of the 2D photograph sets. Categorization processes appear to differ for 3D and 2D stimuli, and infants’ discovery of object properties over time while manipulating objects may facilitate categorization, as least at the superordinate level. These findings are discussed in the context of infants’ representation abilities and the integration of perception and action.     

道德概念的垂直空间隐喻及其对认知的影响

采用不同的研究方法考察道德概念的垂直空间隐喻表征, 及其对于人的认知的影响。实验1采用迫选法, 在明确要求被试把道德词放在垂直空间位置的上方或下方时, 发现在意识层面, 被试倾向于把道德词放在垂直空间的上部, 把不道德词放在垂直空间的下部。实验2采用无关任务法, 对实验词语作褒贬义判断, 实验结果发现, 道德词出现在空间的上方(相对于下方)时, 被试对道德词作褒贬义判断的时间短; 不道德词出现在空间的下方(相对于上方)时, 被试作褒贬义判断的时间则短。实验3通过记忆任务发现, 道德概念的启动使得个体高估了相继出现的客体的高度和长度, 不道德概念的启动使得个体低估了其高度和长度。三个实验的结果表明, 汉语道德概念的垂直空间隐喻具有心理现实性; 汉语道德概念的垂直空间隐喻既存在于无意识层面又可以在意识的层面显现; 汉语道德概念的垂直空间隐喻表征会影响对物体的高度和长度的估计, 表现为汉语道德概念隐喻表征的“认知偏移效应”。     

Electrical conductivity of Nd and Ce co-doped Gd2Zr2O7 ceramics

In this study, (Gd_{1? x} Nd _x )₂(Zr_{1? x} Ce _x )₂O₇ (0 ≤ x ≤ 0.5) ceramics have been prepared by pressureless sintering at 1973 K to investigate the influence of Nd and Ce co-doping on their electrical conductivity. The electrical conductivity of the ceramics was investigated by impedance spectroscopy measurements from 723 to 1173 K over the frequency range of 20 Hz to 2 MHz in air. The measured values obey the Arrhenius relation. For each composition, the grain conductivity gradually increases with increasing temperature from 723 to 1173 K. At a given temperature, it gradually decreases with increasing neodymium and cerium contents from x = 0 to 0.3; thereafter, the grain conductivity exhibits a slight increase with further increasing neodymium and cerium contents up to x = 0.5.
