面孔再认及学习程度判断中的同龄效应

同龄效应指个体对自己年龄段面孔的记忆成绩显著高于其他年龄面孔.实验采用3×3混合设计,考察不同年龄被试对面孔再认及学习程度判断中的同龄效应,探讨同龄效应的发展规律.结果显示,青年和老年人对同龄面孔的再认显著好于异龄面孔,儿童对同龄与异龄面孔的再认成绩差异不显著;各组被试对不同年龄的面孔学习程度判断准确性之间的差异没有区别.这表明:青年和老年人在面孔再认中出现了同龄效应,儿童没有表现出同龄效应;个体学习程度判断中不存在同龄效应,且这种特点与年龄无关.     

身体活动对老年认知功能的影响

如何促进老年人的认知功能, 延缓认知老化, 是老年心理学的关键课题之一。大量研究表明不同的身体活动类型、活动强度、活动量以及生命早期的身体活动可能对老年人认知功能的各个方面有积极的影响, 包括执行功能、注意力、认知速度、记忆力等。此外, 选择性提高假说、心血管功能假说以及认知-锻炼模型用来解释这一影响机制。这些发现对维护老年人认知功能, 提高老年人的生命质量, 有效延缓衰老有着重要的意义。     

道德冲突世界中的生命伦理学:基本争论及干细胞辩论的要点

世界上存在着道德多元性,它表现为生命伦理学的实际道德分布的特征,它是使用人类胚胎作为干细胞来源的争论的根本原因。在世俗文化中,干细胞的使用甚至也会出现疑问。只以从传统的基督教道德直觉和期望的残留影响角度去理解这种现象。关于干细胞的争论反映了更深层次的文化错位。我们正生活在文化战争频发的年代。有必要对罗尔斯学派的关于公共讨论及理性的道德多元化给予重新的关注和评价。     

“Playing God? Yes!” Religion in the Light of Technology

If we appeal to God when our technology (including medicine) fails, we assume a " God of the gaps." It is religiously preferable to appreciate technological competence. Our successes challenge, however, religious convictions. Modifying words and images is not enough, as technology affects theology more deeply. This is illustrated by the history of chemistry. Chemistry has been perceived as wanting to transform and purify reality rather than to understand the created order. Thus, unlike biology and physics, chemistry did not provide a fertile basis for natural theologies. It is argued that an active, transformative role of humans is appropriate in biblically inspired religions and called for in the light of imperfections and evil in the world. When the expression "playing God" is used dismissively, as if we trespass upon God–given territory, a theologically problematical association of God and the given order is assumed. A different view of the human calling can be articulated by drawing upon the Christian heritage and by developing an antinatural religious naturalism.     

Mysterium Tremendum

In recent years, interest in the scientific basis of religious experience has resurged. In particular, research and publications by V. S. Ramachandran and by Eugene d'Aquili and Andrew Newberg have sparked considerable curiosity and debate over the reality and basis of religious experience. This article puts such research into a broader context and examines the extent to which scientific research supports or undermines particular religious and theological claims. I argue that such experiments show that religious experience has some biological basis and is not simply a product of cultural suggestion. At the same time, such experiences are not completely self–interpreting, so that cultural context, including theological claims, are needed to make sense of such experiences. By itself, scientific research does not prove or disprove the reality of religious experiences generally, but it does shape how we think of the possibilities and interpretations of such experiences.     

A Psychobiographical Analysis of Faith, Hope, and Despair in Suicide

This paper presents a psychobiographical analysis of a young woman who committed suicide over 50 years ago. Among the documents analyzed are her letters, a high-school diary, creative writing, college newspaper book reviews, and academic papers. Using both an Eriksonian and object-relational theoretical framework, the roles of faith, hope, and despair in suicide—and the ways in which these were represented in the young woman's self-system—are analyzed. Although she possessed strong elements of both faith and hope, along with a will to implement them in a purposeful manner, she was prone to the defense mechanisms of splitting, devaluation, and dissociation, which led to an inability to create an abiding sense of self that may have prevented her descent to despair. Among other issues discussed in the article are the usefulness of psychobiography as a method of studying suicide and both the benefits and limitations of spiritual faith in countering depression and suicide.     

Dynamics of Religious Group Growth and Survival

We model and analyze the dynamics of religious group membership and size. A group is distinguished by its strictness, which determines how much time group members are expected to spend contributing to the group. Individuals differ in their rate of return for time spent outside of their religious group. We construct a utility function that individuals attempt to maximize, then find a Nash equilibrium for religious group participation with a heterogeneous population. We then model dynamics of group size by including birth, death, and switching of individuals between groups. Group switching depends on the strictness preferences of individuals and their probability of encountering members of other groups. We show that in the case of only two groups—one with finite strictness and the other with zero—there is a parameter combination that determines whether the nonzero strictness group can survive over time, which is more difficult at higher strictness levels. We also show that a high birth rate can allow even the strictest groups to survive. Finally, we consider cases of several groups, gaining insight into strategic choices of strictness values and displaying the rich behavior of the model.     

What's Behind the “Nones‐sense”? Change Over Time in Factors Predicting Likelihood of Religious Nonaffiliation in the United States

The proportion of people in the United States who identify as unaffiliated with any religious tradition (Nones) has risen steadily since the 1990s. Empirical investigations have examined this phenomenon, and point to a range of sociodemographic and associational variables as significant predictors of religious nonaffiliation. To build on these, the research reported here uses nearly five decades of General Social Survey data and binary logistic regression to examine change over time in the direction and size of effect on the likelihood that various factors predict religious nonaffiliation. While some factors (like age and political orientation) behave as expected over time, other factors decrease in their effect on likelihood (e.g., residence in the Far West), lose effect on likelihood (e.g., being college‐educated), or never showed likelihood of effect in the first place (e.g., residence in New England).     

Comparison of prompting procedures to teach internet skills to older adults

The Internet and information and communications technologies (ICTs) have been found to produce meaningful social interactions and greater social support among older adults (White et al., 2002 ). Despite these benefits, the Internet and ICTs are not widely used among the older‐adult population (Cresci, Yarandi, & Morrell, 2010 ). The purpose of the current study was to compare the effectiveness and efficiency of video prompting and text‐based instructions on the acquisition of three tablet‐based tasks: emailing, video calling (FaceTime® application), and searching for a YouTube? video. Both video prompting and text‐based instructions were effective for all three participants, with text‐based instructions being slightly more efficient for one participant and video prompting being more efficient for two participants, suggesting that both prompting procedures can be used to teach older adults Internet and ICT skills.     

How positive and negative contact experiences relate to identification and acculturation of persons with a migration background: Differentiating between majority,minority, and religious group identity

Badea, Jetten, Iyer, and Er-Rafiy proposed a model that specifies immigrants’ experienced rejection by majority and minority groups and social identification with these groups as predictors of their acculturation attitudes. The present research tested an extended version of this model by assessing (i) both positive and negative contact experiences with majority and minority groups, (ii) social identification with these groups and religious groups, and (iii) acculturation attitudes. We surveyed individuals with Greek (N = 186) and Turkish (N = 138) migration background living in Germany. The proposed model yielded a good fit with the empirical data and showed that positive and negative contact with majority and minority groups predicted minority members’ acculturation attitudes, mediated via identification with the majority, minority, and religious group. Our findings support the extended model and contribute to a broader understanding of contact–identification–acculturation links in the context of migration.
