Confidence in perceptual decisions often reflects the probability of being correct. Hence, we predicted that confidence should be unaffected or be minimally decreased by the presence of irrelevant alternatives. To test this prediction, we designed three experiments. In Experiment 1, participants had to identify the largest geometrical shape among two or three alternatives. In the three-alternative condition, one of the shapes was much smaller than the other two, being a clearly incorrect choice. Counter-intuitively, all else being equal, confidence was higher when the irrelevant alternative was present. We accounted for this effect with a computational model where confidence increases monotonically with the number of irrelevant alternatives, a prediction we confirmed in Experiment 2. In Experiment 3, we evaluated whether this effect replicated in a categorical task, but we did not find supporting evidence. Our findings stimulate the use of multi-alternative decision-making tasks to build a thorough understanding of confidence.

Insight Into

Abstract. Folk wisdom tells us that additional time to make a decision helps us to refrain from the first impulse to take the bird in the hand. However, the question why the time to decide plays an important role is still unanswered. Here we distinguish two explanations, one based on a bias in value accumulation that has to be overcome with time, the other based on cognitive control processes that need time to set in. In an intertemporal decision task, we use mouse tracking to study participants’ responses to options’ values and delays which were presented sequentially. We find that the information about options’ delays does indeed lead to an immediate bias that is controlled afterwards, matching the prediction of control processes needed to counter initial impulses. Hence, by using a dynamic measure, we provide insight into the processes underlying short-term oriented choices in intertemporal decision making.

Mental contrasting of a desired future with present reality leads to expectancy-dependent goal commitments, whereas focusing on the desired future only makes people commit to goals regardless of their high or low expectations for success. In the present brief intervention we randomly assigned middle-level managers (N = 52) to two conditions. Participants in one condition were taught to use mental contrasting regarding their everyday concerns, while participants in the other condition were taught to indulge. Two weeks later, participants in the mental-contrasting condition reported to have fared better in managing their time and decision making during everyday life than those in the indulging condition. By helping people to set expectancy-dependent goals, teaching the metacognitive strategy of mental contrasting can be a cost- and time-effective tool to help people manage the demands of their everyday life.

The Relationship

In this paper, I want to try to put what has been termed the “care ethics” into a different perspective. While I will discuss primarily the use of that ethic or that term as it applies to the healthcare setting in general and to the deliberation of consultants or the function of committees more specifically, what I have to say is meant to be applicable to the problem of using a notion like “caring” as a fundamental precept in ethical decision making. I will set out to examine the relationship between theoretical ethics, justice-based reasoning, and care-based reasoning and conclude by suggesting not only that all are part of a defensible solution when adjudicating individual cases, but that these three are linked and can, in fact, be mutually corrective. I will claim that using what has been called “the care ethic” alone is grossly insufficient for solving individual problems and that the term can (especially when used without a disciplined framework) be extremely dangerous. I will readily admit that while blindly using an approach based solely on theoretically derived principles is perhaps somewhat less dangerous, it is bound to be sterile, unsatisfying, and perhaps even cruel in individual situations. Care ethics, as I understand the concept, is basically a non- or truly an anti-intellectual kind of ethic in that it tries not only to value feeling over thought in deliberating problems of ethics, but indeed, would almost entirely substitute feeling for thought. Feeling when used to underwrite undisciplined and intuitive action without theory has no head and, therefore, no plan and no direction; theory eventuating in sterile rules and eventually resulting in action heedlessly based on such rules lacks humanity and heart. Neither one nor the other is complete in itself. There is no reason why we necessarily should be limited to choosing between these two extremes.

Recent developments in contemporary theology and theological ethics have directed academic attention to the interrelationships of theological claims, on the one hand, and core community-forming practices, on the other. This article considers the value for theology of attending to practice at the boundaries, the margins, or, as we prefer to express it, the threshold of a community’s institutional or liturgical life. We argue that marginal or threshold practices can offer insights into processes of theological change – and into the mediation between, and reciprocal influence of, ‘church’ and ‘world’. Our discussion focuses on an example from contemporary British Quakerism. ‘Threshing meetings’ are occasions at which an issue can be ‘threshed out’ as part of a collective process of decision-making. Drawing on a 2015 small-scale study (using a survey and focus group) of British Quaker attitudes to and experiences of threshing meetings, set in the wider context of Quaker tradition, we interpret these meetings as a space for working through – in context and over time – tensions within Quaker theology, practice and self-understandings, particularly those that emerge within, and in relation to, core practices of Quaker decision-making.

Point Of Departure

In Westermann's Monatshefte for January, 1891, and later in his ‘Life of Lessing,‘ Professor Erich Schmidt has outlined the chief features of the history and transformations of the story of the three rings in Europe. On examination it will be found that all the versions of the story belong to one or the other of two types, which are represented by the two earliest forms of the story preserved to us. The oldest version, that of the Spanish Jew Salomo ben Verga, tells of two rings or jewels only, which were in outward appearance exactly alike, and there is no question of one being genuine and the other false, but only of the relative value of the two. In the absence of the father it is found impossible to decide the question, and thus the decision between Christianity and Judaism is simply avoided. In Li Dis dou vrai aniel, a French poem of the end of the twelfth century, three rings appear, and to the original or genuine ring is attributed a marvelous healing power by which it may be recognized, and following which a decision is arrived at among the three religions, in this case in favor of Christianity, although ther were not wanting later narrators so bold as to hint that the true ring was possessed by Judaism. The version of Etienne de Bourbon, the versions of the Cento Novelle, the three versions of the Gesta Romanorum, all belong to one or the other of two types. We may refer to these two types as the Spanish type and the French type. Those of the first type, to which belongs also the version of Boccaccio, the one from which Lessing took his point of departure, avoid a decision, implying that all religions are equally authoritative, but without inherent or inner evidence of their quality. Those of the second type, to which in many of its features Lessing's final version of the story is allied, lead to a decision, making religion of divine origin indeed, but supplying a test, that of good works, whereby the true religion may be recognized.

Substantial Interest

Associative Classification (AC) classifiers are of substantial interest due to their ability to be utilised for mining vast sets of rules. However, researchers over the decades have shown that a large number of these mined rules are trivial, irrelevant, redundant, and sometimes harmful, as they can cause decision-making bias. Accordingly, in our paper, we address these challenges and propose a new novel AC approach based on the RIPPER algorithm, which we refer to as ACRIPPER. Our new approach combines the strength of the RIPPER algorithm with the classical AC method, in order to achieve: (1) a reduction in the number of rules being mined, especially those rules that are largely insignificant; (2) a high level of integration among the confidence and support of the rules on one hand and the class imbalance level in the prediction phase on the other hand. Our experimental results, using 20 different well-known datasets, reveal that the proposed ACRIPPER significantly outperforms the well-known rule-based algorithms RIPPER and J48. Moreover, ACRIPPER significantly outperforms the current AC-based algorithms CBA, CMAR, ECBA, FACA, and ACPRISM. Finally, ACRIPPER is found to achieve the best average and ranking on the accuracy measure.

Two Sides

SummaryRisk assessment has been widely adopted in mental health settings in the hope of preventing harms such as violence to others and suicide. However, risk assessment in its current form is mainly concerned with the probability of adverse events, and does not address the other component of risk – the extent of the resulting loss. Although assessments of the probability of future harm based on actuarial instruments are generally more accurate than the categorisations made by clinicians, actuarial instruments are of little assistance in clinical decision-making because there is no instrument that can estimate the probability of all the harms associated with mental illness, or estimate the extent of the resulting losses. The inability of instruments to distinguish between the risk of common but less serious harms and comparatively rare catastrophic events is a particular limitation of the value of risk categorisations. We should admit that our ability to assess risk is severely limited, and make clinical decisions in a similar way to those in other areas of medicine – by informed consideration of the potential consequences of treatment and non-treatment.

This article is an empirical analysis of history teaching as a communicative process. Dialogic history teaching develops as a designed meaning-making process that depends on thorough pedagogical strategies and decisions, and requires cohesion in teacher expectations, introductions and interventions. A micro-dialogic study is presented in this article to document a paradoxical teaching situation where history as subject-related content all but disappeared from a group of students' meaning-making processes because they were preoccupied with figuring out their teacher's intentions. History teaching thus turned into 'just teaching' without the teacher or the students being aware of it. A strong emphasis on history teaching as a communicative process and dialogue as a key pedagogical tool have potential with regard to pedagogical decision-making and strategies on the one hand, and for relationships between students and history as subject-related content on the other. The analysis presented in this article contributes to a growing field of studies on dialogic history teaching, of which the focus on students as an important part of classroom dialogues is central.

Islamic banking such as the other business institution will face different kind of risk that inherent on its main business activity. In business, risk defined as a posibillity an can appear every time, before, when, and after the decision making. Islamic banking faced different risk with the conventional banking, because its uniquenes. Thus, the development of risk management framework in Islamic banking is very important to do, especially in frame of  risk identification, measuring, mitigation and monitoring. This paper will discuss about risk management in Islamic Banking, in theoretically and the implementation of risk management. The scope of this study will include the identification of risk in Islamic Banking, stage of risk management in Islamic Banking, risk management model, and also the devolpment of risk management framework in Islamic Banking.
