多任务信息加工中的多道分时机制

学术界常用结构理论和资源理论来解释人在多任务信息加工中的作业表现。在多任务中起主要作用的认知能力,其表现形式主要为信息处理的速率以及加工和存储的容量。本研究利用多任务和任务速率的变化来研究信息处理的速率和多任务作业成绩的关系,认为大脑运行的时钟速率是资源的一种形式,大脑对该资源的分配采用多道分时的机制,某个任务获得的时间片越多,该任务的工作绩效就越好。研究表明,在一定的负荷下,信号速率的加快,任务数量的增加,人的作业成绩随着可用时间片的减少而下降。     

目标与非目标数量变化对多目标追踪的选择性抑制效应

采用多目标追踪和点探测刺激觉察任务相结合的实验范式,考察目标和非目标数量变化对多目标追踪的选择性抑制效应。实验一设置非目标恒定而变化目标数量,结果发现：随着目标数量的增加,目标与非目标间的抑制差异量不随目标数量变化而变化。实验二设置目标恒定而变化非目标数量,结果发现：在非目标数量变化的三种水平下,目标与非目标间的抑制差异量也无显著差异。综合实验结果表明：在多目标追踪的追踪容量或抑制容量范围内,抑制差异量对目标数量或非目标数量变化是不敏感的;注意资源分配方式在一定范围内保持相对稳定。     

公共资源两难管理的社会学习过程和动机释放机制

公共资源两难的根本问题是个人经济利益与社会整体利益的矛盾。一些人为了追逐个人利益最大,过度获取公共资源,走向＂公共的悲剧＂,或不愿为公共资源作出贡献,＂搭便车＂现象流行。传统的研究从理性经济人的角度探讨公共资源两难博弈行为的机制,用＂贪婪＂来解释＂搭便车＂现象,并根据强化理论以奖励和惩罚作为主要对策。但是,这种理性经济人观点忽视了人的社会动机。实际上,公共资源两难博弈是一个社会互动的过程,人的社会心理因素在其中起了很重要的作用,因此在方法论上有必要从社会人（Homo socius）的人性观来进行分析。本文在当前的相关研究文献基础上,分析了公共资源两难博弈行为的动机模式,从社会学习理论出发,提出了公共资源两难管理的社会学习过程和动机释放机制。

Physical aggression as a function of perceived fighting ability among male and female prisoners

Study 1 used two scenarios depicting provocations to investigate whether prisoners' willingness to engage in physical aggression would vary according to the perceived fighting ability (Resource Holding Power [RHP]) of the opponent. RHP was operationalized in terms of three levels of the size, number of allies, and reputation. The sample (both sexes; N=1,253) was taken from a range of British prisons. Unexpectedly, the prisoners said that they would be less likely to attack a weaker opponent than an equally matched one. The predicted decline from equally matched to more formidable opponents was found only under some conditions. A further sample of male prisoners (N=260), completed a similar provocation scenario, with response options covering fear, several forms of aggression, the importance of the provocation for reputation, and that the provocation was unimportant. Fear increased with RHP as predicted. Lower physical aggression to a low RHP opponent was again found, and it was associated with a lesser impact on reputation of an insult from this source. There was also a lower likelihood of responding with physical aggression to a high RHP opponent, as originally predicted. Implications of the findings for motivational theories of aggression are discussed, and also the applicability to humans of concepts from game theory models of the evolution of fighting strategies.

Shared structuring resources across domains: double task effects from linguistic processing on the structural integration of pitch sequences

Many studies have reported evidence suggesting that resources involved in linguistic structural processing might be domain-general by demonstrating interference from simultaneously presented non-linguistic stimuli on the processing of sentences (Slevc, Rosenberg, & Patel, 2009 Slevc, L. R., Rosenberg, J. C., & Patel, A. D. (2009). Making psycholinguistics musical: Self-paced reading time evidence for shared processing of linguistic and musical syntax. Psychonomic Bulletin & Review, 16(2), 374–381. doi:10.3758/16.2.374[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). However, the complexity of the analysed linguistic processes often precludes the interpretation of such interference as being based on structural—rather than more general—processing resources (Perruchet & Poulin-Charronnat, 2013 Perruchet, P., & Poulin-Charronnat, B. (2013). Challenging prior evidence for a shared syntactic processor for language and music. Psychonomic Bulletin & Review, 20(2), 310–317. doi:10.3758/s13423-012-0344-5[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We therefore used linguistic structure as a source of interference for another structural processing task, by asking participants to read sentences while processing experimentally manipulated pitch sequences. Half of the sentences contained a segment with either an “out-of-context” sentential violation or a “garden path” unexpectancy. Furthermore, the pitch sequences contained a cluster shift, which did or did not align with the sentential unexpectancies. A two-tone recognition task followed each pitch sequence, providing an index of the strength with which this structural boundary was processed. When a “garden path” unexpectancy (requiring structural reintegration) accompanied the cluster shift, the structural boundary induced by this shift was processed more shallowly. No such effect occurred with non-reintegratable “out-of-context” sentential violations. Furthermore, the discussed interference effect can be isolated from general pitch recognition performance, supporting the interpretation of such interference as being based on overlapping structural processing resources (Kljajevic, 2010 Kljajevic, V. (2010). Is syntactic working memory language specific? Psihologija, 43(1), 85–101. doi:10.2298/PSI1001085K[Crossref], [Web of Science ®] , [Google Scholar]; Patel, 2003 Patel, A. D. (2003). Language, music, syntax and the brain. Nature Neuroscience, 6(7), 674–681. doi: 10.1038/nn1082[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]).     

Negotiating Muslim–Christian Relations in Kenya through Waqfs, 1900–2010

Waqfs provided socio-economic security for the progeny of endowers and for other social welfare causes. Being thus guaranteed socio-economic well-being, these beneficiaries were antithetical to ruling elites in Muslim dynasties and Christian colonial powers, which led to the establishment of policies and institutions to control waqfs and check their growing influence. This development was not only counter to normative precepts but also set minority Muslims in predominantly Christian societies at odds with non-Muslim states. To what extent did civil policies and judgements influence waqfs? How did Muslims negotiate the secular state constructs vis-à-vis waqf practices? How did secular state control of waqfs influence the dynamics of Christian–Muslim relations? This discussion, based on ethnographic research in Kenyan coastal areas, employs two theoretical frameworks – Asad's ‘Islam as a discursive tradition’ and Scott’s concept of ‘symbolic (ideological) resistance’. The article draws mainly on the perspective of the Muslim minority in Kenya and argues that state control of waqfs in Kenya did not only interfere with normative practices but also partly laid the ground for the present-day economic and political marginalization and exclusion of Muslims, leading to suspicion and ambiguous relations with their Christian compatriots.     

Help or Hindrance? Exploring the effects of Christian nurture upon the whole faith of the child

This paper explores the effects that religious nurture (particularly Christian) may have on the child, seeking to provide indicators of whether faith may be viewed as a help or a hindrance. The desire is to indicate the elements of Christian nurture that are most beneficial to the child, through adoption of a broad rather than restricted lens of Christian faith. The EYFS themes: ‘unique child’, ‘positive relationships’, ‘enabling environments’ and ‘learning and development’ were utilised as a guide for formulating the observational indicators. The five case study children all had actively Christian parents who sought to pass their faith onto their child, but each utilised different approaches of faith nurture, enabling comparison of varying styles. The analytical methodology considered 14 observable elements of the child during play-based interviews. Presentation of this data in radar diagrams facilitated a visual representation of the extent to which faith nurture was a resource for the child. When viewed alongside key attributes of the child’s experiences of faith nurture, tentative conclusions were that if openness, individuality and relational involvement are core components of Christian nurture, this will have a positive impact on the broader landscape of the child’s ongoing faith.     

Positive Mood and Future-Oriented Self-Evaluation

When individuals think about their future, feedback on their strengths and weaknesses may often serve as a useful source of information. Three studies investigated the influence of positive and neutral moods on feedback seeking. In Studies 1 and 2, positive mood increased interest in feedback about weaknesses when this information was useful for self-assessment and self-improvement. But when the feedback was not useful for these superordinate, long-term goals then positive mood directed participants’ interest to strength-focused feedback, thereby serving short-term, affective concerns (e.g., feeling good about oneself). Study 3 directly manipulated self-evaluative goals. When a learning goal was activated, positive mood increased interest in weaknesses-focused feedback, but when an affective goal was activated, positive mood increased interest in strength-focused feedback. These results support our hypothesis that positive mood attunes individuals to the relationships of goals and means, thus promoting actions that serve primary goals.
