Previous research showed that fear-inducing graphic warning labels can lead to cognitive dissonance and defensive responses. Less threatening, social-related warning labels do not elicit these defensive responses, making them more effective in preventing smoking in adults. Given that smoking numbers are still too high among youngsters, it is crucial to investigate how warning labels should be designed to prevent teenagers from starting smoking in the first place. In two studies, we investigated whether comparable effects of social-related warning labels could be (...) observed in a group of teenagers (14-17 years) who are not yet legally allowed to smoke. In addition, we tried to replicate earlier findings with smoking and non-smoking adults. Participants were presented with either health warning labels, social warning labels, or no warning labels. Subsequently, their explicit cognitions (i.e., risk perception, attitude towards smoking) and their implicit associations of smoking with healthiness/unhealthiness (Study 1a and Study 1b) and with positivity/negativity (Study 2a and Study 2b) were assessed. Results showed that in both studies, adult smokers had a higher risk perception and a more positive attitude towards smoking than adult non-smokers. Additionally, social warning labels lead to stronger implicit associations between smoking and negativity in Study 2 in the adult groups. In the teenage group, social warning labels lead to more positive attitudes than health warning labels in Study 2. No further effects on risk perception or implicit associations were found in the teenage group. Possible explanations are discussed. (shrink)

Questions about the nature of word meaning have drawn attention across the cognitive science disciplines. Because words are one of the basic units of language, linguists working to describe the design of human language have naturally been concerned with word meaning. Perhaps less obvious, though, is the importance of word meaning to other disciplines. Philosophers seeking to identify the nature of knowledge and its relation to the world, psychologists trying to understand the mental representations and processes that underlie language use, (...) and computer scientists wanting to develop machines that can talk to people in a natural language have all worked to describe what individual words mean, and, more generally, what kind of thing a word meaning is.

When The Emperor of All Maladies was published in late 2010, I knew it would be near the top of my stack of books to read. Since I am a PhD student in the History of Science and Medicine, reading a notable book on the history of cancer and its treatments is a must. Sadly, at the time of its publication, my mother had just died unexpectedly at age 82 of a disease for which she had never received a prior (...) diagnosis: cancer, or acute myelogenous leukemia, to be exact. From diagnosis to death took a mere six days. So I hesitated to take this in-depth look at cancer, a disease that left my family and me stunned and grieving from such a sudden loss. I reasoned, however, that the approach of the book would be detached and scientific, perhaps similar to the tone of the academic tomes that I tackle each week. I began to read. (shrink)

Machery (2009) has proposed that the notion of ‘concept’ ought to be eliminated from the theoretical vocabulary of psychology. I raise three questions about his argument: (1) Is there a meaningful distinction between concepts and background knowledge? (2) Do we need to discard the hybrid view? (3) Are there really categories of things in the world that are the basis for concepts? Although I argue that the answer to all three is ‘no’, I agree with Machery's conclusion that seeking a (...) single characterization of concepts will not be fruitful for understanding cognitive representations and processes.

A crucial step in economic development is the depersonalization of business, which enables an enterprise to operate as a separate entity from its owners and managers. Until the emergence of a de iure depersonalization of business in the 19th century, business activities were eminently personal, with managing partners bearing unlimited liability. Roman law even restricted agency. Yet, the Roman legal system developed a form of de facto depersonalized business entity, where depersonalization was achieved by making the fulcrum of the business (...) a non-person: the slave. Although radically different from a legal perspective, this format exhibited all the distinctive features of modern corporations, thereby providing for a functional equivalent of the modern corporate form. The development of the de iure format was hindered by strong cultural, technological and institutional constraints. In contrast, slave-run businesses exhibited features that were largely compatible with these constraints and emerged along the path of least resistance to legal change. The end of slavery and the fall of the Roman Empire closed off this alternative path of legal evolution; consequently, the modern corporate form could only appear once these constraints had been overcome.

A lengthy debate in the philosophy of the cognitive sciences has turned on whether the phenomenon known as ‘systematicity’ of language and thought shows that connectionist explanatory aspirations are misguided. We investigate the issue of just which phenomenon ‘systematicity’ is supposed to be. The much-rehearsed examples always suggest that being systematic has something to do with ways in which some parts of expressions in natural languages (and, more conjecturally, some parts of thoughts) can be substituted for others without altering well-formedness. (...) We show that under one construal this yields a grossly weak claim that is not just compatible with a narrow version of associationist psychology but essentially coincides with a formalization of its descriptive power. Under another construal we get a claim (apparently unintended) that requires natural languages to fall within the context-free class, a claim that most linguists regard as too strong. Looking more closely at this proposed reconstruction of systematicity leads us to endorse, with further illustrations, the suggestion of Johnson (2004) that systematicity as a matter of substitutability of co-categorial constituents for one another does not appearto hold of natural languages at all. The appeal of the ill-delineated notion of systematicity may lie in the fact that within certain subclasses of lexical items mutual intersubstitutability does seem to hold, and theexplanation for that lies in a limitation on human memory: we simply cannot learn separate privileges of syntactic distribution for all of the huge number of words and phrases that we know.

Bioethics education now takes place outside universities as well as within them. How should clinicians, ethics committee members, and policymakers be taught the ethics they need, and how may their progress best be evaluated?

Young children initially learn to ‘count’ without understanding either what counting means, or what numerical quantities the individual number words pick out. Over a period of many months, children assign progressively more sophisticated meanings to the number words, linking them to discrete objects, to quantification, to numerosity, and so on. Eventually, children come to understand the logic of counting. Along with this knowledge comes an implicit understanding of the successor function, as well as of the principle of equinumerosity, or exact (...) equality between sets. Thus, when children arrive at a mature understanding of counting, they have a way of mentally representing exact, large numbers. (shrink)

Until recently, it was assumed that co-representation of others’ actions, an essential part in joint action, is biologically tuned. However, research demonstrated that we also simulate actions of non-biological interaction partners under certain conditions. In the present study, we investigated whether perceived intentionality or perspective taking is the underlying mechanisms of this phenomenon. Participants saw a short video fragment of a non-biological agent as main character. The movements of this agent were either described as intentional or as unintentional. Furthermore, participants (...) were instructed to either take the perspective of this non-biological agent or not. Results show that perspective taking and perceived intentionality both lead to action co-representation of non-biological actions. Possible explanations for these findings are discussed. (shrink)

This manual presents a carefully researched, detailed psychodynamic treatment program for the alleviation of a transdiagnostic range of primary Axis I anxiety disorders, including panic disorder, generalized anxiety disorder, social anxiety disorder, post-traumatic stress disorder, and related psychological problems. First exploring the principles of psychodynamic theory and formulation, the authors then present a three-phased process of Panic Focused Psychodynamic Psychotherapy-Extended Range : initial evaluation, interpretation of central conflicts and defense mechanisms, and termination. Each phase is discussed in depth and relies (...) on central case illustrations to demonstrate techniques and results. A subsequent chapter explores how to address complex issues that may arise during the course of treatment. Altogether, this manual not only provides a demonstrated, adaptable approach for anxiety disorders, but also clearly embodies a spirit of research and empiricism heretofore rare in psychodynamic psychotherapies, with an eye toward future development.

The purpose of this study was to assess the perceptions of business students and of business practitioners regarding ethics in business. A survey consisting of a series of brief ethical situations was completed by 537 senior business majors and 158 experienced business people. They responded to the situations, first, as they believed the typical business person would respond and, second, as they believed the ethical response would be.The results indicate that both students and business people perceived a significant gap between (...) the ethical response to the given situations and the typical business person's response. Students were significantly more accepting than business people of questionable ethical responses, and they also had a more negative view of the ethics of business people than did the experienced business people.

Do the rich descriptions and narrative shapings of literature provide a valuable resource for readers, writers, philosophers, and everyday people to imagine and confront the ultimate questions of life? Do the human activities of storytelling and complex moral decision-making have a deep connection? What are the moral responsibilities of the artist, critic, and reader? What can religious perspectives—from Catholic to Protestant to Mormon—contribute to literary criticism? Thirty well known contributors reflect on these questions, including iterary theorists Marshall Gregory, James Phelan, (...) and Wayne Booth; philosophers Martha Nussbaum, Richard Hart, and Nina Rosenstand; and authors John Updike, Charles Johnson, Flannery O'Connor, and Bernard Malamud. Divided into four sections, with introductory matter and questions for discussion, this accessible anthology represents the most crucial work today exploring the interdisciplinary connections between literature, religion and philosophy.

To gain insight into human nature philosophers often discuss the inferior performance that results from deficits such as blindsight or amnesia. Less often do they look at superior abilities. A notable exception is Herbert Dreyfus who has developed a theory of expertise according to which expert action generally proceeds automatically and unreflectively. We address one of Dreyfus’s primary examples of expertise: chess. At first glance, chess would seem an obvious counterexample to Dreyfus’s view since, clearly, chess experts are engaged in (...) deep strategic thought. However, Dreyfus’s argument is subtle. He accepts that analysis and deliberation play a role in chess, yet he thinks that all such thought is predicated on intuitive, arational expert perception, and action. We argue that even the so-called intuitive aspect of chess is rational through and through. (shrink)

Bioethicists teaching and writing about the uses of prenatal genetic testing sometimes use “difficult cases” in which people with a disability want to test and select for the presence of their disability. Such cases challenge our stereotypes but also play into them.
