Girotto and Legrenzi's 1993 facilitation effect for their SARS version of Wason s THOG problem a disjunctive reasoning task was examined. The effect was not replicated when the standard THOG problem instructions were used in Experiments 1 and 2. However, in Experiment 3 when Girotto and Legrenzi's precise instructions were used, facilitation was observed. Experiment 4 further investigated the role of the type of instructions in the observed facilitation. The results suggest that such facilitation may result from attentional factors rather (...) than the use of a combinatorial analysis in the problem. (shrink)

Many prescriptions offered in the literature for enhancing creativity and innovation in organizations raise ethical concerns, yet creativity researchers rarely discuss ethics. We identify four categories of behavior proffered as a means for fostering creativity that raise serious ethical issues: breaking rules and standard operating procedures; challenging authority and avoiding tradition; creating conflict, competition and stress; and taking risks. We discuss each category, briefly identifying research supporting these prescriptions for fostering creativity and then we delve into ethical issues associated with (...) engaging in the prescribed behavior. These four rubrics illustrate ethical issues that need to be incorporated into the creativity and innovation literature. Recommendations for how organizations can respond to the ethical issues are offered based on practices of exemplary organizations and theories of organizational ethics. A research agenda for empirically investigating the ethical impact these four categories of behavior have on organizations concludes the article. (shrink)

We sought to expand on the concept of the moral self to include not just the duty to develop the moral self but the moral duty to develop the self in both moral and non-moral ways. To do this, we focused on how leaders can promote a climate in which individuals feel a sense of duty to develop themselves for the betterment of the team and organization. In our theoretical model, duty orientation plays a key role in determining whether followers (...) will seek performance feedback to develop their work selves. We hypothesized that followers with ethical leaders would experience a greater sense of duty to improve themselves and would therefore be more likely to seek and less likely to avoid leader feedback. Drawing on social learning theory, we hypothesized that duty orientation would mediate the relationship between ethical leadership and feedback-seeking/feedback-avoiding behavior, expert power would moderate the relationship between ethical leadership and duty orientation such that duty orientation would be higher when followers perceived their leader to be both highly ethical and competent, and expert power would moderate the indirect effect of ethical leadership on feedback-seeking/feedback-avoiding behavior through duty orientation. We tested our hypotheses using a sample of 249 followers across two waves of data collection. Results suggest that ethical leadership and leader competence interact to drive followers’ duty orientation, thereby reducing followers’ feedback-avoiding behaviors. Further, ethical leadership had a direct positive relationship with followers’ feedback-seeking behaviors. (shrink)

Four experiments are reported which investigated the types of truth tables that people associate with conditional sentences and the kinds of inferences that they will draw from them. The present studies differed from most previous ones in using different types of content in the conditionals, for example promises and warnings. It was found that the type of content had a strong and consistent effect on both truth tables and inferences. It is suggested that this is because in real life conditionals (...) make probabilistic assertions, and that the strength of the probabilistic link is determined by the situation in which the conditional occurs. The implications of these findings for current theories of reasoning are considered and it is concluded that none of them is entirely satisfactory. It is suggested that more linguistically based theories may prove more successful. (shrink)

Many researchers have suggested that premise interpretation errors can account, at least in part, for errors on categorical syllogisms. However, although it is possible to show that people make such errors in simple inference tasks, the evidence for them is far less clear when actual syllogisms are administered. Part of the problem is due to the lack of clear predictions for the solutions that would be expected when using modified quantifiers, assuming that correct inferences are made from them. This paper (...) presents the expected solutions for Gricean, reversible, and reversible Gricean interpretations, and evaluates these using three datasets (two currently available, and one new). The evidence supported the adoption of reversible and reversible Gricean interpretations, but not Gricean interpretations on their own. These results suggest that the categorical syllogism task tends to induce different quantifier interpretations from those identified in simple inference tasks. (shrink)

Stanovich & West's claim that there are two coherent and conceptually distinct types of thinking, System 1 and System 2, is questioned. Some authors equate System 2 with intelligence whereas other do not; and some authors regard the two types of system as distinct while others regard them as lying on a continuum.

Two studies are reported which demonstrate that analytic responding on everyday reasoning problems can be increased and bias eliminated after training on the law of large numbers. Critical thinking problems involving belief-consistent, neutral, and inconsistent conclusions were presented. Belief bias was eliminated when a written justification of argument strength was elicited. However, belief-based responding was still evident when evaluations of the arguments were elicited using rating scales. This finding demonstrates a dissociation between analytic and belief-based responding as a function of (...) response format. In Experiment 2 an instructional condition designed to foster decontextualised reasoning was included but was ineffective in reducing the degree to which judgements were biased by beliefs. It was concluded that training which makes available the analytic strategies necessary to evaluate a problem has the potential to facilitate performance only if the requested response triggers conscious deliberation of the evidence.

(1994). Inductive reasoning, deductive reasoning and mental models. International Studies in the Philosophy of Science: Vol. 8, No. 1, pp. 65-67. doi: 10.1080/02698599408573483.

The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty (...) models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

The notion of ecological rationality, although plausible, does not readily lead to testable predictions. This is illustrated with respect to heuristics in syllogistic reasoning. Several possible heuristics have been proposed but ecological rationality does not appear to offer a sensible rationale for choosing between these.

Nancy is ultimately most concerned about how to determine the relevance of evidence to implementation of evidence-based policy guidelines, in other words, the transferability of study results to a population different from the one that was studied and in which procedures or conditions are not the same as those in the study. And she is concerned about the privileged position Randomized Controlled Trials (RCTs) are given in the ranking schemes for evidence-based policy, because as she sees it RCTs do not (...) address this question while other methods do. RCTs are highly regarded because of their strength in ruling out confounding variables, but they can be weak on the transferability problem because the manipulations necessary for controlled experiment also guarantee that the setting and population are different from the situation and population targeted for application. However, both of these familiar points are simplifications that can be misleading. Some non-RCT type studies (e.g. soft interventions) can also be very good at ruling out confounding variables.1 And, as I will explain, the problems leading to the transferability problem – interacting variables and a difference between study and target populations – are present in any study, not unique to RCTs.

Since our visual perception of physical things essentially involves our identifying objects by their colours, any theory of visual perception must contain some account of the colours of things. The central problem with colour has to do with relating our normal, everyday colour perceptions to what science, i.e. physics, teaches us about physical objects and their qualities. Although we perceive colours as categorical surface properties of things, colour perceptions are explained by introducing physical properties like reflectance profiles or dispositions to (...) cause certain experiences in normal human perceivers. Hence, it seems as if colours as they are experienced by us have no place in the physical world, because they are fundamentally different from the properties which we ascribe to physical objects in scientific accounts of colour perceptions. This special issue on perspectives on colour perception presents new suggestions to solve to this major problem. (shrink)

Baruch Spinoza began his studies learning Hebrew and the Talmud, only to be excommunicated at the age of twenty-four for supposed heresy. Throughout his life, Spinoza was simultaneously accused of being an atheist and a God-intoxicated man. Bertrand Russell said that, compared to others, Spinoza is ethically supreme, 'the noblest and most lovable of the great philosophers'. This book is an exploration of (a) what Spinoza understood God to be, (b) how, for him, the infinite and eternal power of God (...) is expressed, and (c) how finite human beings can have a true idea of this greatest of all entities. Sherry Deveaux begins with an analytic discussion of these three questions, and an explication of three different views held by contemporary commentators on Spinoza. She then shows that the commonly held views about Spinoza are inconsistent with Spinoza's texts, especially his magnum opus, the Ethics. Next comes an analysis of topics in Spinoza that must be understood in order correctly to answer the three questions. For example, the notions of 'power' and 'true idea' are discussed, along with Spinoza's definition of the 'essence' of a thing, which is shown to be central to the discussion of Spinoza's God. Deveaux then claims that Spinoza defines God's essence as 'absolutely infinite and eternal power' and that, contrary to the commonly held view that God's essence is identical with the attributes (e.g., thought and extension), God's essence or "power" is expressed through the attributes.

This article discusses the relationship (or lack thereof) between authors’ intentions and the meaning of literary works. It considers the advantages and disadvantages of Extreme and Modest Actual Intentionalism, Conventionalism, and two versions of Hypothetical Intentionalism, and discusses the role that one’s theoretical commitments about the robustness of linguistic conventions and the publicity of literary works should play in determining which view one accepts.

G. E. M. Anscombe’s view that agents know what they are doing “without observation” has been met with skepticism and the charge of confusion and falsehood. Simultaneously, some commentators think that Anscombe has captured an important truth about the first-personal character of an agent’s awareness of her actions. This paper attempts an explanation and vindication of Anscombe’s view. The key to the vindication lies in focusing on the role of practical knowledge in an agent’s knowledge of her actions. Few commentators, (...) with the exception of Moran (2004) and Hursthouse (2000), have gotten the emphasis right. The key to a proper interpretation of Anscombe’s views is to explain her claims within the context of her teleological theory of action. The result is a theory ofintentional action that makes self-knowledge of one’s own actions the norm. (shrink)

The relationship of the author’s intention to the meaning of a literary work has been a persistently controversial topic in aesthetics. Anti-intentionalists Wimsatt and Beardsley, in the 1946 paper that launched the debate, accused critics who fueled their interpretative activity by poring over the author’s private diaries and life story of committing the ‘fallacy’ of equating the work’s meaning, properly determined by context and linguistic convention, with the meaning intended by the author. Hirsch responded that context and convention are not (...) sufficient to determine a unique meaning for a text; to avoid radical ambiguity we must appeal to the author’s intention, which actualizes one of the candidate meanings. Subsequent writers have defended refined versions of these views, and a variety of positions on the spectrum between them, in a debate that remains central to philosophical aesthetics. This Teaching and Learning Guide lists key readings and suggests how they might be incorporated within a syllabus. It also offers focus questions related to the readings.

Does Cantorian set theory alter our intuitive conception of number? Yes. In particular, Cantorian set theory revises our intuitive conception of when two sets have the same size (cardinal number). Consider a variant of Galileo’s Paradox, which notes that the members of the set of natural numbers, N, can be put in one-to-one correspondence with the members of the set of even numbers, E.

Did Leibniz exploit infinitesimals and infinities à la rigueur or only as shorthand for quantified propositions that refer to ordinary Archimedean magnitudes? Hidé Ishiguro defends the latter position, which she reformulates in terms of Russellian logical fictions. Ishiguro does not explain how to reconcile this interpretation with Leibniz’s repeated assertions that infinitesimals violate the Archimedean property (i.e., Euclid’s Elements, V.4). We present textual evidence from Leibniz, as well as historical evidence from the early decades of the calculus, to undermine Ishiguro’s (...) interpretation. Leibniz frequently writes that his infinitesimals are useful fictions, and we agree, but we show that it is best not to understand them as logical fictions; instead, they are better understood as pure fictions.

The way Leibniz applied his philosophy to mathematics has been the subject of longstanding debates. A key piece of evidence is his letter to Masson on bodies. We offer an interpretation of this often misunderstood text, dealing with the status of infinite divisibility in nature, rather than in mathematics. In line with this distinction, we offer a reading of the fictionality of infinitesimals. The letter has been claimed to support a reading of infinitesimals according to which they are logical fictions, (...) contradictory in their definition, and thus absolutely impossible. The advocates of such a reading have lumped infinitesimals with infinite wholes, which are rejected by Leibniz as contradicting the part–whole principle. Far from supporting this reading, the letter is arguably consistent with the view that infinitesimals, as inassignable quantities, are mentis fictiones, i.e., (well-founded) fictions usable in mathematics, but possibly contrary to the Leibnizian principle of the harmony of things and not necessarily idealizing anything in rerum natura. Unlike infinite wholes, infinitesimals—as well as imaginary roots and other well-founded fictions—may involve accidental (as opposed to absolute) impossibilities, in accordance with the Leibnizian theories of knowledge and modality.
