Do common elements predict class merger: A test of Sidman's theory of equivalence

The study presented here investigated the effect of common and uncommon elements on class merger as predicted by Sidman in his reconceptualization of stimulus equivalence suggesting that common elements among contingencies can facilitate emergent performances (1994, 1997, 2000). Eight adult participants were exposed to a procedure that arranged for stimulus–reinforcer correlations in Phase 1 and response–reinforcer correlations in Phase 2 of a 3-phase study. In the common element group, the visual images serving as reinforcers were the same in Phase 1 and Phase 2. In the uncommon elements group, the images serving as reinforcers were different in Phases 1 and 2. In Phase 3, participants were given an opportunity to respond but no feedback was programmed. The results showed that participants' responding was well differentiated in the common element group and undifferentiated in the uncommon elements group. These results are predicted by Sidman's revised formulation of the provenance and scope of equivalence relations. Specifically, these data support Sidman's (1994, 1997, 2000) suggestion that elements of a contingency enter into an equivalence class and common elements among contingencies are sufficient to produce class mergers. The findings highlight an emergent simple discrimination and raise some interesting considerations about the definition of equivalence under the new formulation.     

群体身份变换性对老年人印象更新的影响：共同内群体认同的中介作用

群体印象更新对于促进群际和谐具有重要的现实意义。本研究采用最简群体再分类范式, 通过4个实验考察了群体身份变换性对老年人外显与内隐印象更新的影响以及共同内群体认同的中介作用。结果发现, 群体身份变换性不仅改变了对最简外群体的印象评价, 而且也提升了年轻人对自然外群体老年人的外显印象评价, 但内隐印象评价的改变不明显; 共同内群体认同在群体身份变换性影响老年人的外显印象更新中起完全中介作用。这些发现不仅从群体身份变换性的视角进一步丰富和拓展了印象更新领域, 而且为群际互动中的偏见消除提供了最简群体再分类新方法。     

公共资源困境中领导对群体成员合作行为的影响

过去社会困境的领导研究大多都以被试作为领导, 发现贴上领导标签后, 被试倾向于拿取更多的公共资源, 从而有碍公共利益的实现。本研究指出, 如果领导的背叛行为能够使群体成员表现出自我节制行为的话, 那么设置领导则有可能促进公共利益的实现。研究通过三个实验, 考察领导与普通群体成员不同的行为方式以及领导的产生方式对群体成员行为的影响, 并检验公平理论和社会认同理论的解释力。研究结果表明, 领导表现出背叛行为时, 被试表现出更多的自我节制行为; 指派领导及外群体选举领导背叛时, 被试表现出更多的自我节制行为, 验证了社会认同理论的正确性。     

Common sense and Berkeley's perception by suggestion

Abstract

Significant attention has been paid to Berkeley's account of perception; however, the interpretations of Berkeley's account of perception by suggestion are either incomplete or mistaken. In this paper I begin by examining a common interpretation of suggestion, the ‘Propositional Account’. I argue that the Propositional Account is inadequate and defend an alternative, non‐propositional, account. I then address George Pitcher's objection that Berkeley's view of sense perception forces him to adopt a ‘non‐conciliatory’ attitude towards common sense. I argue that Pitcher's charge is no longer plausible once we recognize that Berkeley endorses the non‐propositional sense of mediate perception. I close by urging that the non‐propositional interpretation of Berkeley's account of mediate perception affords a greater appreciation of Berkeley's attempt to bring a philosophical account of sense perception in line with some key principles of common sense. While Berkeley's account of perception and physical objects permits physical objects to be immediately perceived by some of the senses, they are, most often, mediately perceived. But for Berkeley this is not a challenge to common sense since common sense requires only that we perceive objects by our senses and that they are, more or less, as we perceive them. Mediate perception by suggestion is, for Berkeley, as genuine a form of perception as immediate perception, and both are compatible with Berkeley's understanding of the demands of common sense.     

Stress,Coping, and Emotions on the World Stage: The Experience of Participating in a Major Soccer Tournament Penalty Shootout

This study was designed to capture the first-hand experiences of stressors, coping, and emotions that elite professional soccer players have during a major soccer penalty shootout. Eight players who each took part in an important European Championships penalty shootout were interviewed. The results showed that the experience of stressors, coping, and emotions changed extensively throughout the event. Moreover, the participants experienced a series of different stressors, some of which were specific to the penalty shootout, and they employed a variety of coping strategies. Anxiety was the most common emotion. Practitioners can use these results to help design valid simulation protocols.     

Much Ado About Something: An Ethic of the Common Good for Information Technology

As the culture of information technology grows and with it the exacerbation of associated problems, so does the body of literature that seeks to reflect on its impact and prospects. The advancements in information technology tend to be outpacing critical reflection and solid ethical analysis. The quality of the foundational ethical work done in information technology ethics has been inadequate, consisting of applied ethics or an appeal to law. This article considers how the richer perspective—the common good, as expressed through the lens of the Roman Catholic Church—can serve as a hermeneutic in the field of information technology ethics, offering a more substantial foundation to address pressing controversial issues associated with this burgeoning field and function as a guide for future developments in this industry. The common good can supplement the operative ways of appealing to law and business ethics to address crime and abuse associated with the World Wide Web with a specifically Roman Catholic paradigm and, in turn, offer a broader and richer appreciation of the societal-wide context that information technology impacts.     

Charting the Attributes of God: The Common Ground of Three Religions according to Ramon Llull (1232–1316)

The Open Letter written by 138 major representatives of Islam to the leaders of the Christian churches, on 13 October 2007, came as something of a surprise. Perhaps more surprisingly, in 1283, the Catalan theologian, Ramon Llull, wrote imaginatively of exactly such a letter in one of his novels, thus demonstrating that the interfaith question is not just a problem of our modern times, which became acute only on September 11. On the contrary, the churches have always been conscious of this interfaith context. Yet methods of tackling the problem have differed widely down the centuries and among Christian traditions. The solution proposed by Ramon Llull and analysed in this article starts from the common acceptance of the attributes of God in all three monotheistic religions. It deserves our attention not only as an interesting historical example but also as a way of avoiding some of our current problems and impasses.     

Criticism of the Theory of Motivation

The theory of motivation is a theory which takes the executora＇s motivation as the basis of moral judgment. One presupposition of the theory is that motivation can be a common object of understanding. However, motivation exists only in the heart of the executor, and cannot be known exactly by others, so motivation cannot be perceived like a common object, and thus, logically, cannot be the basis of moral judgment. Even if the executor＇s motivation is accepted by others and turned into a common object, the motivation still cannot become the valid basis of a moral judgment. This is the dilemma of the theory of motivation. In practice, the dilemma appears as follows： if one insists on the theory of motivation, one can be led to the result that people do evil with good intentions. However, just because motivation cannot be the basis of moral judgment does not mean that motivation is of no significance. Good motivation is always better than evil motivation. Therefore, in moral education we should carry out motivation education and teach people to strive to have good motivations for their behavior. This is the value of motivation theory.     

Dialogue in a learning process: problematization of gender and gender equality in higher education

The overall aim with the study was to describe the knowledge building that was developed in a group of students who were trained nurses enrolled in a Swedish higher education programme. With a point of departure in an interactive research approach, the authors applied the dialogue seminar as method and pedagogical model. When the students in close to practice talks, shared their thoughts about how gender and gender equality could be experienced and understood, the dialogue seminar became useable. At the analysis of the stories which the students shared at the dialogue seminars, it became clear that most of the students had an ambivalent approach to gender equality. When they reflected on gender relations, they brought out the hierarchical and separate gender relations which they experienced as existing within healthcare. Furthermore, their professional lives seemed to be embedded in gender-related practices. An important conclusion is that the students’ reflections oscillated between critical reflection on conditions and critical reflection on processes within their own practice in healthcare. Another finding was that the students’ reflections in dialogue form became important in a learning process, not least in the light of that gender relations and gender equality only to a limited degree had been included in their nurse’s education at the basic level.     

The Common Ratio Effect in Choice,Pricing, and Happiness Tasks

The Allais common ratio effect is one of the most robust violations of rational decision making under risk. In this paper, we conduct a novel test of the common ratio effect in which we elicit preferences for the common ratio choice alternatives in choice, pricing, and happiness rating tasks. We find large shifts in preference patterns across tasks, both within and between subjects. In particular, we find that both the consistency and distribution of responses differ systematically across tasks, with modal choices replicating the Allais preference pattern, modal happiness ratings exhibiting consistent risk aversion, and modal prices maximizing expected value. We discuss the predictions of various cognitive explanations of the common ratio effect in the context of our experiment. We find that a dual process framework provides the most complete account of our results. Surprisingly, we also find that although the Allais pattern was the modal behavior in the choice task, none of the 158 respondents in our experiment exhibited the Allais pattern simultaneously in choice, happiness, and pricing tasks. Our results constitute a new paradox for the leading theories of choice under risk. Copyright © 2017 John Wiley & Sons, Ltd.
