The field of psychology, including cognitive science, is vexed by a crisis of confidence. Although the causes and solutions are varied, we focus here on a common logical problem in inference. The default mode of inference is significance testing, which has a free lunch property where researchers need not make detailed assumptions about the alternative to test the null hypothesis. We present the argument that there is no free lunch; that is, valid testing requires that researchers test the null against (...) a well-specified alternative. We show how this requirement follows from the basic tenets of conventional and Bayesian probability. Moreover, we show in both the conventional and Bayesian framework that not specifying the alternative may lead to rejections of the null hypothesis with scant evidence. We review both frequentist and Bayesian approaches to specifying alternatives, and we show how such specifications improve inference. The field of cognitive science will benefit because consideration of reasonable alternatives will undoubtedly sharpen the intellectual underpinnings of research. (shrink)
Making recognition decisions often requires us to reference the contents of working memory, the information available for ongoing cognitive processing. As such, understanding how recognition decisions are made when based on the contents of working memory is of critical importance. In this work we examine whether recognition decisions based on the contents of visual working memory follow a continuous decision process of graded information about the correct choice or a discrete decision process reflecting only knowing and guessing. We find a (...) clear pattern in favor of a continuous latent strength model of visual working memory–based decision making, supporting the notion that visual recognition decision processes are impacted by the degree of matching between the contents of working memory and the choices given. Relation to relevant findings and the implications for human information processing more generally are discussed. (shrink)
We critically evaluate arguments in a recent Journal of Law, Medicine & Ethics article by Svoboda, Adler, and Van Howe disputing the 2012 affirmative infant male circumcision policy recommendations of the American Academy of Pediatrics. We provide detailed evidence in explaining why the extensive claims by these opponents are not supported by the current strong scientific evidence. We furthermore show why their legal and ethical arguments are contradicted by a reasonable interpretation of current U.S. and international law and ethics. After (...) all considerations are taken into account it would be logical to conclude that failure to recommend male circumcision early in infancy may be viewed as akin to failure to recommend childhood vaccination to parents. In each case, parental consent is required and the intervention is not compulsory. Our evaluation leads us to dismiss the arguments by Svoboda et al. Instead, based on the evidence, infant male circumcision is both ethical and lawful. (shrink)
Eliminativists sometimes invoke evolutionary debunking arguments against ordinary object beliefs, either to help them establish object skepticism or to soften the appeal of commonsense ontology. I argue that object debunkers face a self-defeat problem: their conclusion undermines the scientific support for one of their premises, because evolutionary biology depends on our object beliefs. Using work on reductionism and multiple realizability from the philosophy of science, I argue that it will not suffice for an eliminativist debunker to simply appeal to some (...) object-free surrogate theory of evolution that results from converting any scientific proposition about some object K into a proposition about simples arranged K-wise. In the process, I examine some hazards peculiar to eliminative reductions of scientific theories, and propose a trilemma for eliminativists who attempt to recoup generality for ontologically sparse reducing theories by appealing to pluralities of simples arranged K-wise. The paper is intended to define and develop the object debunker’s self-defeat problem for further study, and to clarify some of the ways sparse and abundant ontologies interact with scientific theory.

Cognitive scientist Donald Hoffman and others have recently advanced an evolutionary debunking argument aimed at our perceptual beliefs in ordinary objects, based on the Interface Theory of Perception. In contrast with most recent criticisms of Interface Theory, which have targeted its characterizations of perception and veridicality, I raise a broad dialectical problem for Hoffman’s debunking argument. I show that the argument is self-defeating, and that responding to this problem by appealing to Universal Darwinism leads to a fatal dilemma for the (...) view. (shrink)
This study modelled associations between gender, ruminative cognitive style, alcohol use, and the time course of negative affect over the course of 43,111 random assessments in the natural environment. Participants completed 49 days of experience sampling over 1.3 years. The data indicated that rumination at baseline was positively associated with alcohol dependence symptoms at baseline as well as higher negative affect over the course of the study. Consistent with negative reinforcement models, drinking served to decrease the persistence of negative affect (...) from moment to moment. However, this ameliorative effect of drinking was evident only among women, suggesting an increased risk for negative reinforcement driven drinking behaviour. In addition, rumination appeared to counteract the desired effects of alcohol on mood among women. This suggests that women who ruminate more may be motivated to consume larger amounts of alcohol to achieve the desired effects. Overall, the results indicate that ruminative cognitive style and the persistence of negative affect from moment to moment may reflect an individual vulnerability for the development of alcohol use disorder especially among women.

This article presents empirical evidence to address how some visitors build relationships with a wildland place over time. Insights are drawn from qualitative interviews of recreation visitors to the backcountry at Rocky Mountain National Park in Colorado. The article describes relationship to place as the active construction and accumulation of place meanings. The analysis is organized around three themes that describe how people develop relationships to place: time and experience accrued in place, social and physical interactions in and with the (...) setting, and an active reflective process of regulating sense of identity to affirm commitment to place.

The Monty Hall Problem (MHP), a process of two-stage decision making, was presented in atypical form via a custom software game. Differing from the normal three-box MHP, the game added one additional box on-screen for each game—culminating on game 23 with 25 on-screen boxes to initially choose from. A total of 108 participants played 23 games (trials) in one of four conditions; (1) “Vanish” condition—all non-winning boxes totally removed from the screen; (2) “Empty” condition—all non-winning boxes remain on-screen, but with (...) an “empty” label on them; (3) “Steroids” condition—all non-winning boxes removed from the screen, with initially chosen box becoming 25% larger; (4) “Steroids2” condition—all non-winning boxes removed from the screen, box not currently chosen becomes 25% larger. Results indicate second-stage on-screen presence of boxes influences switching; with their absence having the opposite effect. Size manipulation appears to elicit demand characteristics resulting in indeterminate influence. (shrink)
This article examines the way in which selfhood is constructed in direct-to-consumer advertisements for antidepressant medications. The sample consists of advertisements that appeared in nine popular magazines between 1997 and 2005, television commercials that ran between 2003 and 2005, and online promotional Web sites. The analysis is divided into three sections. First, it is argued that the ads rely on metaphors of communication, information exchange, and plenitude to construct a relationship between biology and selfhood. Second, in offering the choice for (...) antidepressant treatment, the ads grant individuals a new capacity for the exercise of personal agency. Third, the author describes antidepressants as pills that perform a narrative “magic.” In contrast to religious and psychoanalytic narratives that required individuals to incorporate disavowed elements of their selves into an ongoing life narrative, antidepressants are medications that allow individuals to put aside, or jump over, inexplicable and painful moments in their life.

In this introduction to part 4 of the Common Knowledge symposium “Peace by Other Means,” the journal's editor assesses the argument made by Peace, the spokesperson of Erasmus in his Querela Pacis, that the desire to impute and avenge wrongs against oneself is insatiable and at the root of both individual and social enmities. He notes that, in a symposium about how to resolve and prevent enmity, most contributions have to date expressed caveats about how justice and truth must take (...) precedence over peace, how recovery from ill treatment may be impossible, how quietism is not a moral option, and how realism demands a national policy and a personal strategy of, at best, contingent forgiveness. He concedes that the attitudes of those opposed to quietism are healthy but suggests that there may be goods worthier than health of human devotion. This essay concludes that the main differences between what it terms “judgmental” and “irenic” regimes are disagreements over anthropology and metaphysics. The presumptions that truths are objectively knowable and that human beings are moral and rational agents characterize judgmental regimes; irenic regimes are characterized by disillusionment with those assumptions.

Current arguments to increase shareholder power in the large public U.S. corporation need to take account of the well-established historical practice of extensive delegation by shareholders of business decision-making and agenda-control to management and the board, what might be characterized as an absolute delegation rule. This practice sharply limits the power of shareholders to put either business or governance proposals to the shareholders for dispositive resolution. The paper, originally published in 1991 but newly relevant, argues that the rule is based (...) on potential pathologies in shareholder voting rather than the inherent information asymmetry between shareholders and managers. Rational shareholders who know of this asymmetry (and know that others know) would simply vote against most shareholder proposals. But shareholder voting gives rise to potential cycling problems, as shifting shareholder majorities vie for preferred policies, and potential opportunism, as shareholders engage in side deals with management and other shareholders to extract rents in corporate decision-making. Since shareholding patterns are in part a response to control rights, deviations from the absolute delegation rule will predictably lead to greater block ownership, for defensive and offensive reasons. These concerns need to be addressed in arguments for the expansion of shareholder power. (shrink)

Since its inception, experimental social psychology has arguably been of two minds about the nature and role of theory. Contemporary social psychology's experimental approach has been strongly informed by the “nomological-deductive” approach of Carl Hempel in tandem with the “hypothetico-deducive” approach of Karl Popper. Social psychology's commitment to this hybrid model of science has produced at least two serious obstacles to more fruitful theorizing about human experience: the problem of situational specificity, and the manifest impossibility of formulating meaningful general laws (...) of human social behavior. It is argued that a social psychology based on the search for this kind of lawfulness, under the auspices of either a strict or loose interpretation of the largely Hempelian model, is ultimately unworkable. An alternative approach to social psychology that is attentive both to the need for understanding individual situations and behaviors and to the need for generalized understanding of actual human behaviors is offered. This approach is grounded in the hermeneutic tradition. (shrink)

What is science? What is the purpose of science education? Should we be training scientists, or looking towards a greater public understanding of science? In this exciting text, some of the key figures in the fields of science and science education address this debate. Their contributions form an original dialogue on science education and the general public awareness of science, tackling both formal and informal aspects of science learning. the editors argue that a greater knowledge of science can lead to (...) a better future, but that this can only happen through a mutual understanding between scientists, schools and the public.

ABSTRACT:This essay argues for the importance of formalizing public engagement efforts around bioethics as something we might call "bioethics communication," and it outlines the Johns Hopkins Berman Institute of Bioethics' plans for engaging in this effort. Because science is complex and difficult to explain to nonexperts, the field of science communication has arisen to meet this need. The field involves both a practice and a subject of empirical research. Like science, bioethics is also complex and difficult to explain, which is (...) why the world needs bioethics communication. The authors are engaged in a brand-new effort to establish the sort of public bioethics efforts that would constitute bioethics communication, through a program which they call the Dracopoulos-Bloomberg iDeas Lab. The authors invite colleagues to experiment and learn with them as they invest in the development of bioethics communicators and their products. (shrink)
Students in 1989 were at pains to distinguish their actions from those taken by students in the Cultural Revolution. Yet there were important similarities. In the present paper, we identify influence on the Democracy Movement from the Cultural Revolution through (1) the expansion and/or widespread familiarization of repertories of collective action available to Chinese activists; (2) precedents for collective action that may have lowered the barriers to action for some while raising them for others; (3) the participation of people at (...) different stages of their lives in both movements; (4) the transformation of the significance of the ideas of democracy and political authority wrought by the Cultural Revolution for many Chinese; (5) the impact of the Cultural Revolution on Chinese intellectuals; (6) the material consequences of the Cultural Revolution which contributed to China's position in the post-Mao era and the specific issues reform and protest sought to confront; (7) the discourse of corruption which provided the 1989 movement with its strongest links between students and ordinary citizens, and which was accentuated in the Cultural Revolution; (8) the affirmation of the value of ordinary life by which students in the 1980s, encouraged by the `literature of the wounded', rebelled against the Puritanism and denigration of `unauthorized' personal relationships that had been characteristic of the Cultural Revolution; (9) the role of the Cultural Revolution as a cautionary tale, shaping the movement itself, inhibiting some older intellectuals from participating, and determining much of how the government viewed and responded to the Democracy Movement; and (10) the embeddedness in different ways of both Cultural Revolution and 1989 protests in an international context.
