Is Everything A World?

This paper discusses “inclusionism” in the context of David Lewis’s modal realism (and in the context of parasitic accounts of modality such as\ John Divers’s agnosticism about possible worlds). This is the doctrine that everything is a world. I argue that this doctrine would be beneficial to Divers-style agnosticism; that it suggests a reconfiguration of the concept of actuality in modal realism; and finally that it suffers from an as-yet unsolved difficulty, the problem of the unmarried husbands. This problem also shows that Stephen Yablo’s analysis of “intrinsic” is inadequate. Thanks to Philip Bricker, Ross Cameron, Daniel Nolan, John Divers, Kit Fine, Kris McDaniel, Augustin Rayo, Steve Yablo, to participants in the Arche modality seminar, University of St Andrews, and to the delegates of the APA Pacific Division Conference 2005.     

Belief in Supernatural Evil and Mental Health: Do Secure Attachment to God and Gender Matter?

This study examines whether belief in supernatural evil is associated with mental health. In addition, it assesses how secure attachment to God moderates this association and how gender conditions the moderating effect of secure attachment to God. Among a variety of mental health outcomes, this study focuses on general mental health problems as well as anxiety-related disorders (e.g., general anxiety, social anxiety, and paranoia). Using data from the 2010 Baylor Religion Survey (N = 1,627), the analyses reveal that belief in supernatural evil is positively associated with general anxiety and paranoia. In addition, secure attachment to God buffers the positive associations between belief in supernatural evil and social anxiety and paranoia. Yet, when general mental health problems and general anxiety serve as the outcome measures, secure attachment to God attenuates the positive associations of belief in supernatural evil with mental health only for women, but not men. These results underscore the ways that religious beliefs have both positive and negative implications for mental health. Furthermore, they highlight the importance of gender in the complex relationships between religious beliefs and mental health.     

Moving Toward a Secure Attachment Style: Can Repeated Security Priming Help?

Despite the abundant literature on attachment processes and the development of a secure or insecure attachment orientation during childhood, it is still unclear whether adult attachment style can be changed through systematic interventions, and if so how the change process works. One way to learn more about such change is to create it, on a small scale, in the laboratory. It is already known that a person's sense of security can be momentarily changed in the laboratory ( Mikulincer & Shaver, 2007a ). But there is clearly a difference between very short‐term and longer‐term change. According to Bowlby (1982) , the development of an attachment orientation in childhood is based on many encounters and interactions with caregivers, which gradually create a mental network of relatively stable expectations and concerns. Thus, it may take many episodes of security priming in a laboratory to begin to affect a young adult's attachment style in a lasting way. Here, we explore this possibility, review existing evidence from our own and other researchers’ laboratories, and discuss directions for future research.     

Is the holocaust relevant to sociobiology?

Sociobiologists have emphasized that altruism and benevolent behavior are part of the genetic repertoire of most animals and certainly of man. They have constructed a theory of ethics as a biological phenomenon without reference to the concept of evil. It is concluded here however, that holocaust behavior is not equivalent to the natural manifestation of an incompletely tamed animal flashing its teeth. Biologists have been too rigid in trying to equate ethical behavior with social behavior. The added dimension of ethical behavior is a special kind of sensitivity to the needs of others, just as evil is the total lack of it. The evolution of this moral sense may itself have important selective value for the human species, whose survival depends on creating maximal diversity in its gene pool.     

Is that all there is?

I take issue with two suggestions of Joel Feinberg's: first, that it is incoherent to suppose that human life as such is absurd, and, second, that a particular human life may be absurd and yet saved from being tragic by being fulfilled. I also argue that human life as such may well be absurd and I consider various responses to this.     

Is the hand to speech what speech is to the hand?

Interference between the manual and the verbal performance on two types of concurrent verbal-manual tasks was studied on a sample of 48 female right-handers. The more complex verbal task (storytelling) affected both hands significantly, the less complex (essentially phonemic) task affected only the right hand, with insignificant negative influence on the left-hand performance. No significant reciprocal effects of the motor task on verbalization were found.     

Exposure to successful women: Antidote to sex discrimination in applicant screening decisions?

This research is designed to examine the proposition that exposure to the successes of women in traditionally male occupations will mitigate against subsequent sex bias in selection decisions. Prior to making initial screening decisions about a male or female applicant for a traditionally male job, i.e., finance manager trainee, 147 college students read an editorial documenting the successful performance of an individual woman or a group of women employed in a nontraditional job that either was or was not related to the job about which the personnel recommendations were to be made. A neutral information group read an editorial unrelated to women or work. As predicted, the discrepant ratings of male and female applicants in the neutral baseline condition were significantly reduced only when the information presented concerned a group of women and there also was a direct connection between the occupation in which they were successful and the occupation for which the screening decision was being made. Additional analyses supported the idea that this effect was due to the lessening of the stereotypie attributes used to characterize the female applicants. These results suggest that although exposure to successful women in heretofore male dominated occupations can reduce sex bias in personnel selection decisions, the conditions under which this is likely to occur are very limited. The implications of these results, both theoretical and practical, are discussed.     

Is it disgusting to be reminded that you are an animal?

Six studies (Ns?=?65, 96, 120, 129, 40, 200) tested the hypothesis that being reminded of our animal nature makes us feel disgust. Participants from three cultural groups indicated the intensity of their disgust reactions to pleasant and unpleasant animal reminder stories and pictures as well as to a statement directly reminding them of their animal nature. Findings did not support the hypothesis: Pleasant animal reminders reminded respondents of their animal nature (even more powerfully than did unpleasant ones), but were not disgusting. The direct reminder of our animal nature was not disgusting. There was no significant correlation between disgust and being reminded of animal nature for disgusting (unpleasant) animal reminders. Thus, some disgusting events remind us of our animal nature, but they are not disgusting because they remind us of our animal nature. Animal reminders per se are not disgusting.     

Is the Free Market Acceptable to Everyone?

In this paper we take issue with two central claims that John Tomasi makes in Free Market Fairness (2012). The first claim is that Rawls’s difference principle can better be realized by free market institutions than it can be by state interventionist regimes such as property-owning democracy or liberal socialism. We argue that Tomasi’s narrow interpretation of the difference principle, which focuses largely on wealth and income, leaves other goods (such as control of the workplace and access to economic assets) worryingly unsatisfied. The second claim is that a wide set of economic liberties ought to be protected because they realize responsible ‘self-authorship.’ We argue that this claim also fails because, crucially, whether economic liberties serve individuals in pursuing their ambitions will depend on the nature of those ambitions and how the use of those liberties by others would affect their pursuit of them. If an expansion of liberty is good for us in some ways, but bad in others, we need to assess whether, all things considered, we would be better off with or without such expanded economic rights. We argue that the expansion Tomasi proposes is likely to fail this test.     

What is the answer? And come to that, what are the questions?

In recent years, the topic of car-following has become of increased importance in traffic engineering and safety research. Models of this phenomenon, which describe the interaction between (typically) adjacent vehicles in the same lane, now form the cornerstone for many important areas of research including (a) simulation modelling, where the car-following model (amongst others) controls the motion of the vehicles in the network, and (b) the functional definition of advanced vehicle control and safety systems (AVCSS), which are being introduced as a driver safety aid in an effort to mimic driver behaviour but remove human error. Despite the importance of this area however, no overview of the models availability and validity exists. It is the intent of this paper therefore to briefly assess the range of options available in the choice of car-following model, and assess just how far work has proceeded in our understanding of what, at times, would appear to be a simple process.     

Is Attachment to God a Unique Predictor of Mental Health? Test in a Jewish Sample

Research suggests that religion and spirituality generally correlate positively with various aspects of mental health, although mediators remain unclear. We explored whether attachment to God is a unique predictor above and beyond other key religious variables within a Jewish sample. Given the religion-as-culture perspective suggesting that Judaism can be characterized as primarily focused on behavior versus internal mental experiences, we expected that attachment to God would be less relevant to Jewish mental health. Surprisingly, attachment emerged as the strongest predictor of mental health among both more traditional Orthodox Jewish participants and less traditional non-Orthodox Jews. Although additional cross-cultural research is clearly needed, our results suggest that even in more behaviorally focused religious cultures, attachment to God is a key mediator of the protective effects of religion and spirituality.     

Is the conjunction fallacy tied to probabilistic confirmation?

Crupi et al. (2008) offer a confirmation-theoretic, Bayesian account of the conjunction fallacy—an error in reasoning that occurs when subjects judge that Pr(h ₁ & h ₂|e) > Pr(h ₁|e). They introduce three formal conditions that are satisfied by classical conjunction fallacy cases, and they show that these same conditions imply that h ₁ & h ₂ is confirmed by e to a greater extent than is h ₁ alone. Consequently, they suggest that people are tracking this confirmation relation when they commit conjunction fallacies. I offer three experiments testing the merits of Crupi et al.’s account specifically and confirmation-theoretic accounts of the conjunction fallacy more generally. The results of Experiment 1 show that, although Crupi et al.’s conditions do seem to be causally linked to the conjunction fallacy, they are not necessary for it; there exist cases that do not meet their three conditions in which subjects still tend to commit the fallacy. The results of Experiments 2 and 3 show that Crupi et al.’s conditions, and those offered by other confirmation-theoretic accounts of the fallacy, are not sufficient for the fallacy either; there exist cases that meet all three of CFT’s conditions in which subjects do not tend to commit the fallacy. Additionally, these latter experiments show that such confirmation-theoretic conditions are at best only weakly causally relevant to the presence of the conjunction fallacy. Given these findings, CFT’s account specifically, and any general confirmation-theoretic account more broadly, falls short of offering a satisfying explanation of the presence of the conjunction fallacy.     

Is imitation learning the route to humanoid robots?

This review investigates two recent developments in artificial intelligence and neural computation: learning from imitation and the development of humanoid robots. It is postulated that the study of imitation learning offers a promising route to gain new insights into mechanisms of perceptual motor control that could ultimately lead to the creation of autonomous humanoid robots. Imitation learning focuses on three important issues: efficient motor learning, the connection between action and perception, and modular motor control in the form of movement primitives. It is reviewed here how research on representations of, and functional connections between, action and perception have contributed to our understanding of motor acts of other beings. The recent discovery that some areas in the primate brain are active during both movement perception and execution has provided a hypothetical neural basis of imitation. Computational approaches to imitation learning are also described, initially from the perspective of traditional AI and robotics, but also from the perspective of neural network models and statistical-learning research. Parallels and differences between biological and computational approaches to imitation are highlighted and an overview of current projects that actually employ imitation learning for humanoid robots is given.     

Is the implicit association test immune to faking?

One of the main advantages of measures of automatic cognition is supposed to be that they are less susceptible to faking than explicit tests. It is an empirical question, however, to what degree these measures can be faked, and the response might well differ for different measures. We tested whether the Implicit Association Test (IAT, Greenwald, McGhee, & Schwartz, 1998) cannot be faked as easily as explicit measures of the same constructs. We chose the Big-Five dimensions conscientiousness and extraversion as the constructs of interest. The results show, indeed, that the IAT is much less susceptible to faking than questionnaire measures are, even if no selective faking of single dimensions of the questionnaire occurred. However, given limited experience, scores on the IAT, too, are susceptible to faking.
