动态面孔表情优势效应的心理机制及神经基础

动态面孔表情优势效应是指较静态面孔表情而言, 个体在识别动态的面孔表情时表现出较好的识别能力。动态面孔表情优势效应的心理机制主要涉及增强的构形加工、补偿角色和面孔模仿能力。此外, 该优势效应的神经网络则由核心的神经网络和扩展的神经网络组成, 前者主要负责早期的知觉编码和刺激的运动加工, 而后者与个体的面孔模仿能力、刺激的动态表征等有关。今后的研究应集中在完善延伸的神经网络、拓展其心理机制; 开展动态面孔表情优势效应的发展性研究; 考察面孔表情的刚性运动特征; 注重在虚拟现实环境下研究动态面孔表情的优势效应。     

Honoring the Bios in Lutheran Bioethics

Abstract:  A Lutheran bioethic honors the body by being anti‐Gnostic (and finding moral wisdom in the body's limits), by being anti‐Pelagian (and requiring the reshaping of our disordered desires), and by being anti‐Sadducean (in affirming that the new creation, though continuous with and fulfilling the old, also transforms and perfects it in ways that go beyond the earthly life we know). Such an approach to bioethics is illustrated here through discussion of the way in which new reproductive technologies may distort our understanding of the relation between the generations, thereby losing sight of the bios in bioethics.     

Work and Family Commitment and Decision-Making Status Among Emerging Adults

This study was designed to investigate work–family attitudes among emerging adults. Participants were 46 male and 49 female college juniors and seniors. Men and women had similar levels of work and family commitment. For women there was a negative correlation between work and family commitment. Exploratory analyses indicated different relationships between work decision-making status and commitment and family decision-making status and commitment. In addition, whereas men were more likely than women not yet to have thought about family roles, women were more likely than men to have decided about family roles. Implications of these findings for our understanding of the processes and meanings of emerging adult men's and women's decisions about entry into and commitment toward work and family roles are discussed. Although earlier literature employs the term “young adults” to refer to individuals in the emerging adult stage of development, for the sake of consistency we use the term “emerging adults” throughout this article.     

When less is more: Psychometric properties of Norwegian short‐forms of the Ambivalent Sexism Scales (ASI and AMI) and the Illinois Rape Myth Acceptance (IRMA) Scale

This paper reports on the development and the psychometric properties of short forms of Ambivalent Sexism Scales toward women (ASI; Glick & Fiske, 1996) and men (AMI; Glick & Fiske, 1999), and a scale measuring rape stereotypes (IRMA; McMahon & Farmer, 2011). The short form AMI/ASI were applied for examining gender and educational differences in university students (N = 512) and in high school students (N = 1381), and for predicting individual differences in rape stereotypes in the latter. The short forms demonstrated good to excellent psychometric properties across samples of emerging adults. Relative to female students, male students reported markedly more hostility toward women and more stereotypical beliefs about rape. Despite sampling from a highly gender egalitarian and secular culture, these gender differences are on a par with those reported internationally. Rape stereotypes were predicted by sexism in high school students. Additional predictors were educational program, relationship status, and acceptance of derogatory sexual slurs. The paper questions the validity of separate constructs for benevolent sexism toward women versus men. The short form versions of the scales may substitute the original versions in future research, and help prevent attrition while measuring the same constructs.     

Connect within to connect outside: effect of salespeople's political skill on relationship performance

Scholars have recently explored the effects of salespeople's intraorganizational relationships on salespeople's job-related outcomes. Grounded in social influence theory, we explore the effects of salespeople's intraorganizational skills on salesperson relationship performance. We empirically tested the proposed relationships using the data from a non-Western sales force working with an organization in an emerging economy. The results indicate that salespeople's political skill positively contributes to salespeople's identification with the organization and to creative performance, while strikingly, we also find that salesperson task adaptivity weakens these effects. Moreover, salespeople's identification and creative performance are positively related to customer satisfaction. These findings demonstrate that salespeople's intraorganizational relationships play a key role in enhancing customer satisfaction. In light of these results, we explore implications for marketers and academics and conclude by suggesting directions for further research.     

Cross‐sectional study of violence in emerging adulthood

Theories of emerging adulthood, the evolutionary perspective, and the presence of turning points in the lives of 19–25‐year olds were examined in relation to serious perpetrated violence for a cross‐sectional sample of men and women (n=14,098) from the National Longitudinal Study of Adolescent Health (Add Health), Wave III. Perpetrated, self‐reported violence included armed robbery, gang fighting, using a weapon in a fight, pulling a knife or gun on someone, or shooting or stabbing someone. Results showed that 11.3% of emergent adults had perpetrated at least one of these behaviors in the past year. Hierarchical logistic regression analysis partially supported the three theories for both men and women, beyond the contribution of violence in adolescence. The presence of Wave III violence was more likely given the unique contributions of unmarried status and economic risk. Moreover, and consistent with the theory of emerging adulthood, both sensation seeking and depression declined with age and contributed to the acknowledgement of Wave III violence, beyond the contribution of controls for Wave I violence (6 years earlier), demographics, age, gender, unmarried status, and economic risk. Findings of age‐related declines and gender differences in prevalence rates were consistent with previous research on nationally representative samples, and with the predictions of the three theories.

Visual Technologies, Cosmographies, and Our Sense of Place in the Universe

The first part of this paper surveys the visual technologies that have transformed the modern visual environment and argues for the relevance of their study to an understanding of modernity in general and to the field of religion and science in particular. The term cosmography is adopted for the visual and spatial manifestation of a worldview, and the importance of analyzing and advancing modern cosmography is asserted. In the second part, the focus shifts to one particular challenge presented by modern cosmography: how to represent and find visual meaning in the new range of size scales that have been offered up by the modern scientific worldview. Six strategies for representing and finding meaning in this new expanded picture of the universe are explored.     

Perceiving Other Planets: Bodily Experience,Interpretation, and the Mars Orbiter Camera

An emerging philosophical perspective called “postphenomenology,” which offers reflection upon human relations to technology, has the potential to increase our understanding of the functions performed by imaging technologies in scientific practice. In what follows, I review some relevant insights and expand them for use in the concrete analysis of practices of image interpretation in science. As a guiding example, I explore how these insights bear upon a contemporary debate in space science over images of the fossilized remains of a river delta on the surface of Mars. These considerations include an analysis of the ways that the objects of study are transformed by the mediating imaging technologies, such as the Mars Orbiter Camera.

Counselling Australian baby boomers: examining the loss and grief issues facing aging distance-separated sibling dyads

It has long been recognised that mature-aged sibling dyads provide each other with emotional support. What has yet to be determined is whether this support function is maintained within the baby boomer generational cohort of sibling dyads who through economic relocation/migration have become separated by distance. As such, this paper highlights the need for research to be conducted into the experiences of baby boomers dealing with sibling loss and grief-related issues without the support of their nuclear and extended family members.     

失用性失写的脑机制

失用性失写是指人们知道该如何书写, 但实际上却不会书写或错误书写的一种现象。失用性失写涉及的神经网络包括皮层与皮层连接、皮层与皮质下连接。其中前者包括额-顶叶相关脑区的连接、顶-枕叶相关脑区的连接以及额-顶-枕相关脑区的连接, 这些神经网络分别负责操作空间表征图像、回忆以及检索字母的形状等; 后者包括小脑与额-顶叶的连接、左丘脑-大脑皮质的连接以及纹状体-内囊-左额顶叶的连接等, 它们分别与图像输出程序、书写运动过程、操作指令的执行过程以及字素形成过程等有关。今后的研究应该集中在完善失用性失写的研究范式、深入探讨失用性失写的心理机制以及推动其康复工作的开展等方面。
