Simple actions influence pop-out search

Recent research has revealed that a simple action (pressing a computer key) produced in response to a visual object prioritizes features of that object in subsequent visual search. The effects of simple action, however, have only been studied with search displays that required serial search. Here we explored whether simple actions have an effect when the target in visual search is always a salient singleton. Participants viewed a coloured shape at the beginning of each trial, and sometimes they acted (pressed the space bar) in response to it. In the subsequent search task, after acting (but not after viewing), the previously-seen colour affected search performance even though the target was always a salient singleton and the colour was uninformative. The results reveal that prior action can interact with bottom-up salience during search. Implications for our understanding of both visual search and repetition priming are discussed.     

Setiya on reasons and causes

Setiya [2013. “Causality in Action”. Analysis Reviews, 73 (3): pp. 512–525] recently gave a novel argument in favor of a causal theory of acting for a reason. He presents three principles relating acting for a reason to psychological states of the agent and uses them to test theories of acting for a reason: theories cannot explain the necessary truth of the conditionals are to be rejected. Surveying a number of alternatives, he finds that only a causal-psychological theory passes this test, that, thus, it must be correct, and that there must be a solution to the problem of deviant causation. Setiya's challenge is forceful, but he does not establish his conclusion. The anticausalist can at this point reverse it: since deviant causation is intractable, some noncausal theory must be able to meet his challenge. This reversal has teeth: Setiya underestimates both the challenges that causal theories face and the resources available to the anticausalist to address his challenge.     

Hijab in the American workplace: visibility and discrimination

While the initial purpose of this article was to outline online collective action (OCA) towards promoting the rights of hijab-wearing Muslim women in the workplace, it became apparent that there were substantial impediments to this solidarity. Thus, the bulk of it takes up these obstacles, arguing that American hijabis face structural discrimination and Muslims in the United States are subjected to heightened discrimination when they are highly visible to the mainstream culture. This article reviews two cases of workplace discrimination against hijabis and the reactions to these incidents on the Huffington Post, Los Angeles Times, and hijab-oriented blogs. Findings indicate that intolerance of Muslims is prevalent across various political affiliations and apprehension associated with hijabi rights could be related to the perceived decline of white privilege. The analysis also demonstrates that there may be impediments to solidarity with hijabi rights within Muslim communities due to disagreements on the Qur’anic mandate of modesty, divergent perspectives on how Muslims can best promote their rights and ensure their safety, and misunderstandings related to the rights guaranteed under reasonable accommodation. Despite the various obstacles to solidarity with hijabis, the article traces various forms of OCA at local, national and international levels that were encountered on social media platforms.     

KAGAWA TOYOHIKO (1888–1960): WITNESS TO THE COSMIC DRAMA

At home and abroad, Kagawa Toyohiko was probably the best‐known Japanese Christian evangelist, social reformer, writer, and public intellectual of the twentieth century, nominated for the Nobel Prize in Literature twice (1947, 1948) and the Nobel Peace Prize three times (1954, 1955, 1956). Appealing to the masses with little knowledge of Christian faith, Kagawa believed that a positive, religio‐aesthetic interpretation of nature and science was a key missiological concern in Japan. He reasoned that a faith rooted in the kenotic movement of incarnation and self‐giving must strongly support the scientific quest. A voracious reader of science and especially biology, he argues for “directionality,” or what he calls “initial purpose” in the long, painful, cosmic journey from matter to life to mind (or consciousness). Through an antireductionistic, a posteriori methodological pluralism that sought to “see all things whole,” this “scientific mystic” employed Christian, Buddhist, Neo‐Confucian, personalist, and vitalist ideas to envision complementary roles for science and religion in modern society.     

Revisiting self-regulatory techniques to promote physical activity in older adults: null-findings from a randomised controlled trial

Objective. A randomised controlled trial (RCT) was conducted to evaluate a three-hour face-to-face physical activity (PA) intervention in community-dwelling older German adults with four groups: The intervention group (IG) received behaviour change techniques (BCTs) based on the health action process approach plus a views-on-ageing component to increase PA. The second intervention group ‘planning’ (IGpl) contained the same BCTs, only substituted the views-on-ageing component against an additional planning task. An active control group received the same BCTs, however, targeting volunteering instead of PA. A passive control group (PCG) received no intervention.

Design. The RCT comprised 5 time-points over 14 months in N = 310 participants aged 64+.

Main outcome measures. Self-reported as well as accelerometer-assessed PA.

Results. Neither PA measure increased in the IG as compared to the other groups at any point in time. Bayes analyses supported these null-effects.

Conclusion. A possible explanation for this null-finding in line with a recent meta-analysis is that some self-regulatory BCTs may be ineffective or even negatively associated with PA in interventions for older adults as they are assumed to be less acceptable for older adults. This interpretation was supported by observed reluctance to participate in self-regulatory BCTs in the current study.     

自闭症碎镜理论之迷思:缘起、问题与前景

自闭症患者在社会沟通和交往障碍上主要涉及社会情感互动缺陷、非语言行为交流缺陷、发展维持和理解人际关系的缺陷。该群体在社会认知过程中潜在自动的直觉成分受损被视为其独特的临床症状。鉴于镜像神经元系统在社会认知的直觉成分上扮演的重要角色,该系统的功能障碍假说(或称"碎镜"理论)被提出并用以解释自闭症的成因及其异常表现。然而,在经历了10年的发展与证据检验后,该理论潜在的问题逐渐暴露。当前的研究显示,迄今为止人类镜像神经元系统的研究存在内在缺陷,镜像神经元系统至多是社会认知的附带原因,该系统功能障碍也并非自闭症患者社会认知障碍的必要条件。碎镜理论面临来自临床行为研究与认知神经科学实验证据的广泛质疑。未来,伴随自闭症研究对象的变化,镜像神经元的社会响应学说的提出,双个体范式、第二人称神经科学范式与计算精神病学的兴起,镜像神经元与自闭症的真正关系将有望得以阐明。

Palestinian Educational Philosophy Between Past and Present

The article discuses the education issue as a central and decisive factor inshaping, reproducing and representing individual and collective identity.I present the Palestinian case study because the Palestinian people are atthe present in a very critical period of constructing their national identityand education is part of the nation-building project. I have chosen to studytwo periods in the life of Palestinians, 1972 during the revolution and thepresent 1999 the start of the establishment of an independent Palestinianentity and to examine how the economic, social, political conditions etc.affect the formation of the educational philosophy of those periods; aneducational philosophy that will affect the formation of education and theformation of private and collective consciousness.     

Appreciating a Scientist-Theologian: Some Remarks on the Work of John Polkinghorne

Perhaps the greatest irony about the contemporary religion-science dialogue is the fact that, despite their own strongly articulated denials, many thinkers implicitly accept the "warfare" thesis of A. D. White—that is, they agree with White that traditional theology has proved unable to engage science in fruitful conversation. More than most others, John Polkinghorne understands just how badly White misread the history of Christianity and science, and how much theology has been impoverished by its failure to challenge this core assumption of modernity.
