Some Current Trends of Christianity in Africa

This article examines three trends in current African Christianity. Its denominational fragmentation is currently marked by the coexistence of three major groups: the “churches that emerged from the apostolic process of Christian antiquity”; the “churches born from Western missionary processes”; and the “African revivalists” (African initiated churches and African Pentecostal churches). The African revivalists are characterized by doctrinal and institutional creativity that largely draws on Africa's historical trajectory, with its challenges of a sociocultural, identity, and economic nature. This “fragmented African Christianity” inevitably has a diverse view of African cultures, ranging from a positive viewpoint on one end of the scale and radical rejection on the other, and including various patterns of taking over Christian heritage with the goal of giving new value to the formally scorned African identity. This diversity of attitudes in turn prompts overall judgments on Christianity in Africa, which range from praise to suspicion regarding the pertinence of this religion on the continent. This complex shape of current African Christianity is not an obstacle to the Ad Gentes mission, whose current dynamism is increasingly marked by the phenomenon of African emigration. All of this represents a great challenge for ecumenism, because a trend toward a “religion market” is taking the lead over collaboration and search for Christian unity. This is why it is important to recognize the quality of this African missionary Christianity, whose fragmentation is quite original.     

Complexity,Progress, and Hierarchy in Evolution

In this article I suggest a view of evolution characterized as a progressive process toward successively higher levels of complexity. In this approach, complexity is defined by means of an operational definition giving the possibility of its measurement by means of a procedure in which development has a crucial role. Furthermore, the concept of competition applied in the complexity space explains the cumulative emergence of new species as well as the presence of stagnant species. In this process, species are formed in a hierarchical order in which the human species is situated on the highest level. This view of evolution, thus also embracing human cultural evolution, is depicted in a diagram of complexity versus time, thus forming a new kind of a Tree of Life. The purpose of the suggested interpretation of evolution is to make it more readily acceptable for common people.     

Can We Forget What We Know in a False‐Belief Task? An Investigation of the True‐Belief Default

It has been generally assumed in the Theory of Mind literature of the past 30 years that young children fail standard false‐belief tasks because they attribute their own knowledge to the protagonist (what Leslie and colleagues called a “true‐belief default”). Contrary to the traditional view, we have recently proposed that the children's bias is task induced. This alternative view was supported by studies showing that 3 year olds are able to pass a false‐belief task that allows them to focus on the protagonist, without drawing their attention to the target object in the test phase. For a more accurate comparison of these two accounts, the present study tested the true‐belief default with adults. Four experiments measuring eye movements and response inhibition revealed that (a) adults do not have an automatic tendency to respond to the false‐belief question according to their own knowledge and (b) the true‐belief response need not be inhibited in order to correctly predict the protagonist's actions. The positive results observed in the control conditions confirm the accuracy of the various measures used. I conclude that the results of this study undermine the true‐belief default view and those models that posit mechanisms of response inhibition in false‐belief reasoning. Alternatively, the present study with adults and recent studies with children suggest that participants' focus of attention in false‐belief tasks may be key to their performance.     

A discussion of Kretchmar’s elements of competition

Recently Kretchmar attempted to apply and to explore Husserl’s transcendental phenomenological method in relation to clarifying, in the context of sport particularly, the main features of competition. He concludes with the strong claim that competition is unintelligible unless understood in relation to the four elements of plurality, comparison, normativity, and disputation. Roughly, the idea is that competition needs to be understood as a context in which more than one competitor is involved; where competitors are compared; that comparisons are evaluations of their performance/entry in the competition; and that the expected result of the latter is a matter of dispute between or among contestants. In investigating these points some refinement of this basic outline is attempted against occasional reference to others who in the past made similar claims about the conditions of competition. I conclude that Kretchmar’s claims are mistaken.     

Rankings,standards, and competition: Task vs. scale comparisons

Research showing how upward social comparison breeds competitive behavior has so far conflated local comparisons in task performance (e.g. a test score) with comparisons on a more general scale (i.e. an underlying skill). Using a ranking methodology ( Garcia, Tor, & Gonzalez, 2006) to separate task and scale comparisons, Studies 1–2 reveal that an upward comparison on the scale (e.g. being surpassed in rank), rather than in the mere task (e.g., being outperformed), is necessary to generate competition among rivals proximate to a standard (e.g. ranked #3 vs. 4, near “the top”); rivals far from a standard (e.g. ranked #203 vs. 204), on the other hand, still tend to cooperate. Study 3 illustrates this finding with player trades in Major League Baseball. Study 4 further shows how an implicit scale comparison, instead of the commonly assumed explicit task comparison, may account for those classical competition findings in the literature. Study 5 then reveals how scale ranking becomes all important in the proximity of a standard, leading rivals to tolerate even an upward scale comparison to increase their proximity to the standard. Implications for the increasingly popular “forced ranking” management systems (e.g., at General Electric) are also discussed.     

Concurrent visual search and time reproduction with cross-talk

Previous experiments indicate that humans can reproduce a time interval while concurrently searching a visual display presented near the beginning of the reproduced interval (Fortin, C., Rousseau, R., Bourque, P. & Kirouac, E. (1993). Time estimation and concurrent nontemporal processing: Specific interference from short-term-memory demands. Perception & Psychophysics, 53, 536-548.). In the earlier experiments, reproduced intervals were either insensitive to or shortened with increasing duration of visual search, suggesting that reproduction and search proceeded concurrently but sometimes with cross-talk. Here we test concurrency of time reproduction and visual search using a different methodology than before. Assuming the underlying mental processes are in a critical path network, factors selectively influencing concurrent processes are predicted to produce certain patterns in response time means and, through recent developments, certain patterns in cumulative distribution functions. Processes in an experiment were influenced by manipulating four factors, the time interval to be produced, stimulus onset asynchrony, display size, and target presence/absence. Patterns in response times provide evidence for concurrent time reproduction and visual search. However, a prediction based on selective influence failed in a manner suggesting the presence of cross-talk produced by a filled interval illusion.     

The Perverse Effects of Competition on Scientists’ Work and Relationships

Competition among scientists for funding, positions and prestige, among other things, is often seen as a salutary driving force in U.S. science. Its effects on scientists, their work and their relationships are seldom considered. Focus-group discussions with 51 mid- and early-career scientists, on which this study is based, reveal a dark side of competition in science. According to these scientists, competition contributes to strategic game-playing in science, a decline in free and open sharing of information and methods, sabotage of others’ ability to use one’s work, interference with peer-review processes, deformation of relationships, and careless or questionable research conduct. When competition is pervasive, such effects may jeopardize the progress, efficiency and integrity of science.     

团队作业与团队互动两类共享心智模型的发展特征

共享心智模型指团队成员关于团队作业、策略、团队情境、团队互动等的共同的知识结构,根据内容不同可以分为团队作业模型和团队互动模型两类。该研究通过实验室实验探讨两类共享心智模型的发展特征。132名大学生组成44个3人团队,随机分为团队绩效反馈组和无团队绩效反馈组。采用相似性评定法在团队执行作业前、中、后三次测量两类共享心智模型。结果发现：（1）共享心智模型随团队运作时间增加而发展;（2）团队互动模型形成和发展的难度高于团队作业模型;（3）团队绩效反馈对两类心智模型发展的作用不同,反馈加速了团队作业模型的发展速度,但却是团队互动模型能否得以发展的决定性因素。两类共享心智模型的不同发展特征应归因于两者特异性高低的不同     

Reciprocal Relations between Emerging Adults’ Representations of Relationships with Mothers,Fathers, and Romantic Partners

This study employed a fully cross-lagged, longitudinal model to examine reciprocal relations between representations of relationships with parents and romantic partners at ages 20 and 22. Representations were assessed with continuous measures of dismissing/avoidant and preoccupied relationship styles across the attachment and affiliation systems for parents, and across the attachment, affiliation, and caregiving systems for romantic partners. Earlier relationships with both mothers and fathers independently predicted changes in later views of romantic relationships, and earlier romantic relationships predicted changes in later views of relationships with both mothers and fathers. This evidence of a developmental system of interconnected representations across relationships has theoretical implications about the nature of working models, and practical implications alerting parents to the onset of dating as a potentially fertile context for changes in their relationships with children.
