目光注视线索对客体注意的影响及作用机制

目光注视在人类社交以及捕获和维持注意方面发挥重要作用。但是, 目光注视如何与客体交互以引导注意分配至今尚不明确。因此, 本研究采用双框线索范式, 以具有两种注视方向(直视或回避)的面孔或实物作为客体, 通过操纵线索到目标间的SOA来考察目光注视对客体注意的影响及作用机制。实验1发现, 目光注视对客体效应的影响只出现在300 ms SOA时; 进一步分析发现, 客体效应的差异来自于直视条件下被试对无效相同客体位置上的目标比回避条件下反应更快。这表明与回避目光相比, 直视更能捕获我们的注意, 从而产生更大的客体效应。实验2将面孔对比度反转, 排除了低水平物理特征对实验1结果的影响。实验3使用两种注视方向的眼睛叠加杯子作为客体, 以探究目光注视效应是否能扩展到其他客体中, 结果与实验1相同。本研究结果表明, 目光注视能够与客体交互共同引导注意分配, 直视更能捕获注意, 但受SOA的影响, 上述结果支持了感觉增强理论。

Learning from human tutoring

Human one-to-one tutoring has been shown to be a very effective form of instruction. Three contrasting hypotheses, a tutor-centered one, a student-centered one, and an interactive one could all potentially explain the effectiveness of tutoring. To test these hypotheses, analyses focused not only on the effectiveness of the tutors' moves, but also on the effectiveness of the students' construction on learning, as well as their interaction. The interaction hypothesis is further tested in the second study by manipulating the kind of tutoring tactics tutors were permitted to use. In order to promote a more interactive style of dialogue, rather than a didactic style, tutors were suppressed from giving explanations and feedback. Instead, tutors were encouraged to prompt the students. Surprisingly, students learned just as effectively even when tutors were suppressed from giving explanations and feedback. Their learning in the interactive style of tutoring is attributed to construction from deeper and a greater amount of scaffolding episodes, as well as their greater effort to take control of their own learning by reading more. What they learned from reading was limited, however, by their reading abilities.     

Towards an African Theology of Reconciliation: A Missiological Reflection on the Instrumentum Laboris of the Second African Synod

This essay is a critical theological and pastoral study of the Working Document of the Second African Synod. The article engages the articles in the document which deal with the theme of reconciliation. This essay begins by exploring the Christological and ecclesiological foundations for an African theology of reconciliation as found in the working document. While engaging the significant aspects of the working document which relate to articulating an African theology of reconciliation, this essay shows the limitations of the document in its historical and cultural analysis of the situation in Africa. Drawing from a phenomenological hermeneutical engagement with African history, cultural grammar, and Christ‐centered African Christian imagination, the essay widens the scope of theological engagement with the task of reconciliation in Africa. It does a theological aesthetics of reconciliation in Africa, by integrating diverse cultural, ontological, and Christological symbols within the African world on vital participation and vital union. Through the inculturation of vital participation as analogous to Trinitarian Communion, the essay shows how the Church in Africa can deal with the ever‐revolving cycle of violence, conflicts, and divisions in the churches and political institutions which have all hampered the mission of building relationship and God's kingdom in Africa. The essay concludes by recommending four pastoral approaches through which the Catholic Church in Africa can be both a reconciled community and an instrument for reconciliation in Africa.     

Using game theory to examine incentives in influenza vaccination behavior

The social good often depends on the altruistic behavior of specific individuals. For example, epidemiological studies of influenza indicate that elderly individuals, who face the highest mortality risk, are best protected by vaccination of young individuals, who contribute most to disease transmission. To examine the conditions under which young people would get vaccinated to protect elderly people, we conducted a game-theory experiment that mirrored real-world influenza transmission, with "young" players contributing more than "elderly" players to herd immunity. Participants could spend points to get vaccinated and reduce the risk of influenza. When players were paid according to individual point totals, more elderly than young players got vaccinated, a finding consistent with the Nash equilibrium predicting self-interested behavior. When players were paid according to group point totals, however, more young than elderly players got vaccinated-a finding consistent with the utilitarian equilibrium predicting group-optimal behavior-which resulted in higher point totals than when players were paid for their individual totals. Thus, payout structure affected whether individuals got vaccinated for self-interest or group benefit.     

Nourishing or suppressing? The contradictory influences of perception of organizational politics on organizational citizenship behaviour

Drawing on both social exchange theory and impression management theory, this study sought to explain how perception of organizational politics (POP) influences organizational citizenship behaviour (OCB) through two contrary psychological processes. We proposed that through the mediation of job satisfaction, POP has an inhibiting effect on OCB; through the mediation of careerism, POP has a nourishing effect on OCB. Data were obtained from 393 police officers and their colleagues from a city police department in northern Taiwan. Results from structural equation modelling (SEM) revealed that the relationship between POP and OCB was negatively mediated by job satisfaction and positively mediated by careerism. Such antithetical psychological processes imply that employees may experience psychological dilemmas over the performance of OCB when they perceive their organization as political. Implications for theory and future research are discussed.     

孕12周～14周血小板计数及平均血小板体积对子痫前期的预测作用

Executive function on the Psychology Experiment Building Language tests

The measurement of executive function has a long history in clinical and experimental neuropsychology. The goal of the present report was to determine the profile of behavior across the lifespan on four computerized measures of executive function contained in the recently developed Psychology Experiment Building Language (PEBL) test battery and evaluate whether this pattern is comparable to data previously obtained with the non-PEBL versions of these tests. Participants (N = 1,223; ages, 5–89 years) completed the PEBL Trail Making Test (pTMT), the Wisconsin Card Sort Test (pWCST; Berg, Journal of General Psychology, 39, 15–22, 1948; Grant & Berg, Journal of Experimental Psychology, 38, 404–411, 1948), the Tower of London (pToL), or a time estimation task (Time-Wall). Age-related effects were found over all four tests, especially as age increased from young childhood through adulthood. For several tests and measures (including pToL and pTMT), age-related slowing was found as age increased in adulthood. Together, these findings indicate that the PEBL tests provide valid and versatile new research tools for measuring executive functions.     

诠释与转换：积极心理健康及其当代理解

积极心理健康是积极心理学理论系统的一个重要组成部分,也是积极心理学理论本身在心理健康领域的一种应用。积极心理健康以积极为核心观念,以人的积极品质为研究对象,注重人的个体差异的研究思路,引领和推动传统心理健康从关注人的消极品质转向人的积极潜力,从而使心理健康的主题既符合时代潮流又具有深厚的思想底蕴。
