I agree with Gibbs that the message of the base rate literature reads differently depending on which null hypothesis is used to frame the issue. But I argue that the normative null hypothesis, H0: “People use base rates in a Bayesian manner,” is no longer appropriate. I also challenge Adler's distinction between unused and ignored base rates, and criticize Goodie's reluctance to shift research attention to the field. Macchi's arguments about textual ambiguities in traditional base rate problems suggest (...) that empirical testing is needed to tease apart the effects of problem clarification and problem framing. Macdonald's, Fletcher's and Snow's skepticism about the value of Bayesian methods in real world judgment tasks is treated as a challenge for the next generation of empirical base rate studies.

During the mid-18th century, when electricity was coming into its own, natural philosophers began to entertain the possibility that electricity is the mysterious nerve force. Their attention was first drawn to several species of strongly electric fish, namely torpedoes, a type of African catfish, and a South American "eels." This was because their effects felt like those of discharging Leyden jars and could be transmitted along known conductors of electricity. Moreover, their actions could not be adequately explained by popular mechanical (...) theories. Many of the early documents supportive of the hypothesis of animal electricity were associated with the Dutch colonies in South America. This article presents and examines those documents, and shows how Dutch scientists on both sides of the Atlantic conducted experiments and communicated with each other in the 1750s and 1760s. It reveals the important roles played by inquisitive physicians and lovers of nature in South America, and by natural philosophers and collectors of exotic specimens in the Netherlands—learned men who began to make a credible case for animal electricity in some exciting places at a pivotal moment in time.

An analytic cognitive style denotes a propensity to set aside highly salient intuitions when engaging in problem solving. We assess the hypothesis that an analytic cognitive style is associated with a history of questioning, altering, and rejecting supernatural claims, both religious and paranormal. In two studies, we examined associations of God beliefs, religious engagement, conventional religious beliefs and paranormal beliefs with performance measures of cognitive ability and analytic cognitive style. An analytic cognitive style negatively predicted both religious and paranormal (...) beliefs when controlling for cognitive ability as well as religious engagement, sex, age, political ideology, and education. Participants more willing to engage in analytic reasoning were less likely to endorse supernatural beliefs. Further, an association between analytic cognitive style and religious engagement was mediated by religious beliefs, suggesting that an analytic cognitive style negatively affects religious engagement via lower acceptance of conventional religious beliefs. Results for types of God belief indicate that the association between an analytic cognitive style and God beliefs is more nuanced than mere acceptance and rejection, but also includes adopting less conventional God beliefs, such as Pantheism or Deism. Our data are consistent with the idea that two people who share the same cognitive ability, education, political ideology, sex, age and level of religious engagement can acquire very different sets of beliefs about the world if they differ in their propensity to think analytically.

Tversky and Koehler's support theory attempts to explain why probability judgments are affected by the manner in which formally similar events are described. Support theory suggests that as the explicitness of a description increases, an event will be judged to be more likely. In the present experiment, experienced decision-makers from large, international accounting firms were given case-specific information about an audit client and asked to provide a series of judgments regarding the perceived likelihood of events. Unpacking a hypothesis into (...) four formally equivalent hypotheses more than doubled its perceived likelihood. These results are largely consistent with support theory, extending its generalizability to applied contexts involving business professionals. Further, the paper finds that task-specific factors, a previously untested area, can also affect support theory interpretations. (shrink)

I defend Spinoza's claim that extension is an attribute that an indivisible substance, such as God, could have. However, in order to explain why, we must abandon two long held orthodoxies in Spinoza scholarship. First, Spinoza acknowledges only parts that do not depend on their whole. Second, God, considered as natura naturans, has no parts of any kind. Against these orthodoxies, I show that having parts which depend on their whole, for Spinoza, does not entail divisibility and that God, considered (...) as natura naturans, must have such parts in order to be extended. Along the way, we will have a closer look at Spinoza’s mereology and address apparently conflicting statements that Spinoza makes about the relation of part and whole that have long vexed commentators.

This essay presents Mendelssohn’s neglected vindication of theism through a refutation of Spinoza’s philosophy in the Morgenstunden and highlights its relevance for discussions in contemporary philosophy of religion. For this purpose, I (i) contextualise Mendelssohn's argument within the reception of Spinoza at the dawn of the 18th century, (ii) trace the path of Mendelssohn's argument to theism, (iii) and examine Mendelssohn's argument in light of Linda Zagzebski's account of divine omniscience showing that her account is not only incoherent but also (...) undermines the theistic assumption that the world has an existence outside of God.

O objetivo deste artigo consiste em analisar como Nietzsche, baseado na filosofia schopenhauriana, resolveu o problema do surgimento da tragédia grega através da elevação dos elementos Apolo e Dionísio a um estatuto ontológico, e como os gregos fizeram isso em seu tempo através da Música, além de revelar como, em Nietzsche, o pensamento de Sócrates surge como o “perverso algoz da arte”.O estudo foi realizado através de uma pesquisa bibliográfica com base nas seguintes obras do filósofo: A visão Dionisíaca de (...) Mundo e O nascimento da tragédia no espírito da Música. Na segunda parte, sugere-se como Nietzsche faz esse resgate do trágico em sua época e qual a recepção no século XIX de seu trabalho. (shrink)

_Published by Taylor & Francis Group for the American Association of Colleges for Teacher Education_ This _Handbook_ addresses the concept and implementation of technological pedagogical content knowledge -- the knowledge and skills that teachers need in order to integrate technology meaningfully into instruction in specific content areas. Recognizing, for example, that effective uses of technology in mathematics are quite different from effective uses of technology in social studies, teachers need specific preparation in using technology in each content area they will (...) be teaching. Offering a series of chapters by scholars in different content areas who apply the technological pedagogical content knowledge framework to their individual content areas, the volume is structured around three themes: What is Technological Pedagogical Content Knowledge? Integrating Technological Pedagogical Content Knowledge into Specific Subject Areas Integrating Technological Pedagogical Content Knowledge into Teacher Education and Professional Development The _Handbook of Technological Pedagogical Content Knowledge for Educators_ is simultaneously a mandate and a manifesto on the engagement of technology in classrooms based on consensus standards and rubrics for effectiveness. As the title of the concluding chapter declares, "It’s about time!" The American Association of Colleges for Teacher Education is a national, voluntary association of higher education institutions and related organizations. Our mission is to promote the learning of all PK-12 students through high-quality, evidence-based preparation and continuing education for all school personnel.

Empathy means understanding another person’s emotional or intentional state by vicariously sharing this state. As opposed to emotional contagion, empathy is characterized by the self–other distinction of subjective experience. Empathy develops in the second year, as soon as symbolic representation and mental imagery set in that enable children to represent the self, to recognize their mirror image, and to identify with another person. In experiments with 126 children, mirror recognition and readiness to empathize with a distressed playmate were investigated. Almost (...) all recognizers showed compassion and tried to help, whereas nonrecognizers were perplexed or remained indifferent. Several motivational consequences of empathy are discussed and its special quality is outlined in comparison with theory of mind and perspective taking. (shrink)

We have been oversold on the base rate fallacy in probabilistic judgment from an empirical, normative, and methodological standpoint. At the empirical level, a thorough examination of the base rate literature (including the famous lawyer–engineer problem) does not support the conventional wisdom that people routinely ignore base rates. Quite the contrary, the literature shows that base rates are almost always used and that their degree of use depends on task structure and representation. Specifically, base rates play a relatively larger role (...) in tasks where base rates are implicitly learned or can be represented in frequentist terms. Base rates are also used more when they are reliable and relatively more diagnostic than available individuating information. At the normative level, the base rate fallacy should be rejected because few tasks map unambiguously into the narrow framework that is held up as the standard of good decision making. Mechanical applications of Bayes's theorem to identify performance errors are inappropriate when (1) key assumptions of the model are either unchecked or grossly violated, and (2) no attempt is made to identify the decision maker's goals, values, and task assumptions. Methodologically, the current approach is criticized for its failure to consider how the ambiguous, unreliable, and unstable base rates of the real world are and should be used. Where decision makers' assumptions and goals vary, and where performance criteria are complex, the traditional Bayesian standard is insufficient. Even where predictive accuracy is the goal in commonly defined problems, there may be situations (e.g., informationally redundant environments) in which base rates can be ignored with impunity. A more ecologically valid research program is called for. This program should emphasize the development of prescriptive theory in rich, realistic decision environments. (shrink)

Self–other distinction, as documented by mirror self-recognition (MSR), allows for empathy which offers a motivational base for helping a person in need. Kärtner and Keller propose a different, culture-related, possibility of helping based on shared intentional relations and emotional contagion which could explain helping behavior in Indian children not yet capable of MSR. Due to the experimental setting, however, other releasers of children’s sadness and helping behavior have to be considered. An alternative setting is proposed. With respect to MSR, the (...) question of false negatives is discussed. The issues mentioned by Klann-Delius address fundamental theoretical questions that cannot be answered briefly. (shrink)

Mental time travel and theory of mind develop, both phylo- and ontogenetically, at the same stage. We argue that this synchrony is due to the emergence of a shared competence, namely, the ability to become aware of frames of reference.

There is a distinction between locality and modularity. These two terms have often been used interchangeably in the target article and commentary. Using this distinction we argue in favor of a modularity. In addition we also argue that both PDP-type networks and box-and-arrow models have their own strengths and pitfalls.

Early psychosocial stress (e.g., parental divorce, abuse) is conjectured to place individuals on a developmental trajectory leading to earlier initiation of sexual activity, earlier reproduction, and having more sex partners than those with less early psychosocial stress. But does it also affect an individual’s mate choice? The present study examined whether early psychosocial stress affects preferences and dislikes for opposite-sex faces varying in masculinity/femininity, a putative indicator of mate quality, in premenopausal women (58 with a natural cycle, 53 pill-users) and (...) 196 men. No significant three-way interactions were found when women selected the most or least preferred face with participant group (natural cycle, pill), conception risk (low, high), and early psychosocial stress (low, high) as between-subjects factors. Early psychosocial stress did not affect men’s face preferences when selecting the most preferred face. However, men with high early psychosocial stress disliked masculine faces significantly more so than men with low early psychosocial stress. Overall it was concluded that early psychosocial stress does not affect mate choice with the exception that men with high early psychosocial stress were more likely to dislike masculine female faces. It was suggested that men with high early psychosocial stress may dislike masculine female faces because they have nothing to gain from associating with women with such faces. (shrink)

When the social relevance of robotic applications is addressed today, the use of assistive technology in care settings is almost always the first example. So-called care robots are presented as a solution to the nursing crisis, despite doubts about their technological readiness and the lack of concrete usage scenarios in everyday nursing practice. We inquire into this interconnection of social robotics and care. We show how both are made available for each other in three arenas: innovation policy, care organization, and (...) robotic engineering. First, we analyze the discursive “logics” of care robotics within European innovation policy, second, we disclose how care robotics is encountering a historically grown conflict within health care organization, and third we show how care scenarios are being used in robotic engineering. From this diagnosis, we derive a threefold critique of robotics in healthcare, which calls attention to the politics, historicity, and social situatedness of care robotics in elderly care. (shrink)
