Reversed better-than-average effect in direct comparisons of nonsocial stimuli depends on the set size

Studies on direct comparative judgments typically show that, for items that are positively evaluated, a single item randomly drawn from a larger set of similar items tends to be judged as better than average (the BTA effect). However, Windschitl, Conybeare, and Krizan (2008) demonstrated that, under timing conditions that do not favor focusing attention on the single item, the reversal of the BTA effect occurs. We report two experiments showing that the magnitude of the reversed BTA effect increases as a function of the size of a multiitem referent with which a single item target is compared. Specifically, in direct comparative judgments of the attractiveness of positively evaluated objects (nice-looking cloth buttons, attractive buildings, or cupcakes), underestimation of the attractiveness of singletons, as compared with a multiitem set (reversed BTA effect), increased with the increased set size. Analysis of absolute judgments obtained for singletons and for small and large multiitem sets suggests that, for attractive stimuli, both the reversed BTA effect in comparative judgments and its sensitivity to set size occur as a result of a positive relationship between set size and perceived attractiveness in absolute judgments.     

BONE MARROW TRANSPLANTATION IN A PATIENT WHO EXPERIENCED TORTURE IN A PRISONER OF WAR CAMP: NARCISSISM AND SURVIVAL

Post-traumatic stress disorder has been described as a syndrome from which an individual may suffer as a result of extraordinary trauma. Torture of prisoners of war in Serbian camps during the war in Croatia is just such a stressful situation that requires mobilization of all defense mechanisms of an individual. The authors present a case study of a former prisoner of war who acquired acute myelogenous leukemia several months after release and was treated with bone marrow transplantation. On release the patient was medically examined, like all prisoners of war, and the findings did not suggest any disease. Because of the situation, the patient was in psychotherapeutic observation and treatment after his illness was diagnosed and throughout the transplantation treatment.     

Abstract argumentation and explanation applied to scientific debates

Abstract argumentation has been shown to be a powerful tool within many fields such as artificial intelligence, logic and legal reasoning. In this paper we enhance Dung’s well-known abstract argumentation framework with explanatory capabilities. We show that an explanatory argumentation framework (EAF) obtained in this way is a useful tool for the modeling of scientific debates. On the one hand, EAFs allow for the representation of explanatory and justificatory arguments constituting rivaling scientific views. On the other hand, different procedures for selecting arguments, corresponding to different methodological and epistemic requirements of theory evaluation, can be formulated in view of our framework.     

Kuhn and the Question of Pursuit Worthiness

The aim of this paper is, on the one hand, to critically investigate Kuhn’s stance on the assessment of the pursuit worthiness of scientific theories, and, on the other hand, to show the actuality of some of Kuhn’s points on this issue, in view of their critical analysis. To this end we show that Kuhn presents certain tools, which may help scientists to overcome communication breakdowns when engaging in the process of rational deliberation regarding the question whether a theory is worthy of further pursuit. These tools are persuasion, translation and interpretation. However, we argue that the perspective of epistemic semantic monism present in Kuhn’s work obstructs the full applicability of these tools. We show that dropping this perspective makes the notions of persuasion and interpretation more fruitful, and moreover, allows for a pluralism of scientific theories and practices that complements the pluralism based on disagreement among scientists, emphasized by Kuhn.     

You Can Only Die Thrice: Death and Dying of a Human Body in Psychoanalytical Perspective

This paper compares the (cultural) necessity of death/dying, perceived as a sequence of Imaginary—Real—Symbolic, to Van Gennep’s three-staged rite of passage. If this logic is disrupted, the subject responsible necessitates attribution of special social status and can come to embody the imagery of a life worth living. This philosophical framework, which includes epistemologies borrowed from medical anthropology, demonstrates there is more for humans to lose than biological (Real) life; a far greater loss is to exist without (Symbolic) reason to live. A critique of prevalent quantitative methodology in assessing links between spirituality and the human body is added.     

Varieties of Religious and Pornographic Experience: Latent Growth in Adolescents’ Religiosity and Pornography Use

The relationship between adolescent religiosity and pornography use has been longitudinally tested only in the United States. Given the social relevance of hypothesized mechanisms underlying the association, this study offers a three-wave longitudinal assessment of parallel latent growth in the two constructs carried out in a Southern European country. Using responses of 1,041 Croatian adolescents from the capital city (M_age = 16.14 years, SD = .45; 64.6% of female students) and latent growth curve modeling approach, we explored links between individual trajectories of change in religiosity and pornography use over a period of 24 months. In the observed period, religiosity decreased and pornography use increased among both male and female adolescents, but their dynamics were independent of each other—pointing to other (unmeasured) processes responsible for both adolescents’ sexualization and secularization. Important to note, the findings also pointed to an important role of age at first exposure to pornography for its frequency of use in middle to late adolescence.     

Differential sensitisation to central cardiovascular effects of angiotensin II in rats with a myocardial infarct: relevance to stress and interaction with vasopressin

The purpose of the present study was to elucidate if rats with myocardial infarction manifest altered responsiveness to central cardiovascular effects of low doses of angiotensin II (ANG II), and if ANG II and vasopressin (VP) cooperate in the central regulation of cardiovascular functions at rest and during stress. Conscious Sprague-Dawley rats with myocardial infarction induced by left coronary artery ligation, or sham-ligated (SL) controls were infused intracerebroventricularly with artificial cerebrospinal fluid (aCSF), ANG II, ANG II + VP or ANG II + V1a receptor antagonist (V1ANT) 4 weeks after cardiac surgery. In the infarcted but not in the SL rats, the resting mean arterial blood pressure (MABP) was significantly elevated by infusions of ANG II and ANG II + VP, while infusion of ANG II + V1ANT was not effective. During administration of aCSF, the pressor, and tachycardic responses to an air-jet stressor were significantly greater in the infarcted than in the SL rats. In the SL rats, the pressor responses to the stressor were significantly greater during infusions of ANG II, ANG II + VP and ANG II + V1ANT than during infusion of aCSF. The tachycardic response in the SL rats was enhanced only by the combined infusion of ANG II + VP. In the infarcted rats, the pressor and the tachycardic responses to the stressor were similar in all groups. It is concluded that: (1) under resting conditions the infarcted rats manifest sensitisation to the central pressor effect of ANG II and that this effect depends on concomitant stimulation of V1a VP receptors, (2) central ANG II may enhance the pressor response to an alarming stressor in the SL rats through an action which does not depend on the concomitant stimulation of V1a receptors, (3) the cooperative action of ANG II and VP is required for intensification of the tachycardic response to the alarming stressor in the SL rats and (4) exaggeration of the cardiovascular responses to the alarming stressor in the infarcted rats cannot be further augmented by an additional stimulation of central ANG II receptors or combined stimulation of ANG II and VP receptors.     

Explanation and Understanding: Action as “Historical Structure”

The first part of this essay is basically historical. It introduces the explanation–understanding divide, focusing in particular on the general–unique distinction. The second part is more philosophical and it presents two different claims on action. In the first place, I will try to say what it means to understand an action. Secondly, we will focus on the explanation of action as it is seen in some explanatory sciences. I will try to argue that in some cases these sciences commit what I call an “external contradiction”.
