Barbosa da Silva Antonio 《Christian Bioethics: Non-Ecumenical Studies in Medical Morality》2009,15(1):54-73
This article assesses the similarity and difference betweenthe Western European style of doing bioethics and the Scandinavianone. First, it reviews the introductory article by the editor,C. Delkeskamp-Hayes in the first issue of Christian Bioethics(2008), devoted to the possibility of a specifically Christianbioethics in Europe. Second, it analyses bioethics debates inScandinavian today. In light of Delkeskamp-Hayes' article, themain similarity is that both regions are facing secularizationas a threat to basic Christian values, for example, to the Christianview of the sanctity and dignity of the human life. But theScandinavian tends to reduce Christian bioethics to Luther'sconcept of the worldly kingdom, supposed to foster a dialoguebetween Christians and non-Christians on controversial ethicalissues. Despite the positive value of the dialogue, this strategyrenders Christian ethics powerless. Third, from an evangelicaltheological standpoint, it proposes some strategies for enhancingthe influence of Christian commitments on bioethical laws andpolicies. 相似文献

Mirror Neurons and the Evolution of Embodied Language 总被引:3,自引:0,他引:3
Leonardo Fogassi Pier Francesco Ferrari 《Current directions in psychological science》2007,16(3):136-141
ABSTRACT— Mirror neurons are a class of neurons first discovered in the monkey premotor cortex that activate both when the monkey executes an action and when it observes the same action made by another individual. These neurons enable individuals to understand actions performed by others. Two subcategories of mirror neurons in monkeys activate when they listen to action sounds and when they observe communicative gestures made by others, respectively. The properties of mirror neurons could constitute a substrate from which more sophisticated forms of communication evolved; this would make sense, given the anatomical and functional homology between part of the monkey premotor cortex and Broca's area (the "speech" area of the brain) in humans. We hypothesize that several components of human language, including some aspects of phonology and syntax, could be embedded in the organizational properties of the motor system and that a deeper knowledge of this system could shed light on how language evolved. 相似文献

CaMeRa: A Computational Model of Multiple Representations 总被引:1,自引:0,他引:1

This research aims to clarify, by constructing and testing a computer simulation, the use of multiple representations in problem solving, focusing on their role in visual reasoning. The model is motivated by extensive experimental evidence in the literature for the features it incorporates, but this article focuses on the system's structure. We illustrate the model's behavior by simulating the cognitive and perceptual processes of an economics expert as he teaches some well-learned economics principles while drawing a graph on a blackboard. Data in the experimental literature and concurrent verbal protocols were used to guide construction of a linked production system and parallel network, CaMeRa (Computation with Multiple Representations), that employs a "Mind's Eye" representation for pictorial information, consisting of a bitmap and associated node-link structures. Propositional list structures are used to represent verbal information and reasoning. Small individual pieces from the different representations are linked on a sequential and temporary basis to form a reasoning and inferencing chain, using visually encoded information recalled to the Mind's Eye from long-term memory and from cues recognized on an external display. CaMeRa, like the expert, uses the diagrammatic and verbal representations to complement one another, thus exploiting the unique advantages of each. 相似文献

Philosophical and neuroscientific investigation on intentional actions focused on several different aspects, making difficult to define what should be meant with the concept of intention. Most of our everyday actions are constituted by complex and finely organized motor sequences, planned and executed in order to attain a desired final goal. In this paper, we will identify the final goal of the action as the motor intention of the acting individual. First, we will review the relative contribution of the vast neuroscientific literature on the role of different cortical areas in the organization of goal-directed movement. In particular, we will describe recent data on the cortical organization of natural action sequences, showing that this organization could be at the basis not only of our capacity of acting intentionally, but also of our ability to understand the motor intentions underlying others’ behaviour which is crucial during social interactions. 相似文献

The aim of this study was to create an explanatory model that allows analyzing the predictive power of a set of variables related to political knowledge; more specifically, to analyze the relationship between the education level of young adults and the variables, interest in politics and internal political efficacy. We also analyzed the combined relationship between these variables, together with age, and political knowledge. We worked with a sample group of 280 young adults between the ages of 18-30 from the city of Córdoba (Argentina). The data was subjected to a structural equation modelling SEM analysis, which allowed for the corroboration of the following hypotheses: the higher the education level, the more the interest in politics; the higher the education level, the better the perception of internal political efficacy; the higher the education level, the more the political knowledge; the more the interest in politics, the more the political knowledge; and the better the perception of internal political efficacy, the more interest in politics. Moreover, the following hypotheses could not be verified: the older an individual, the more the political knowledge; and the better the perception of internal political efficacy, the more the political knowledge. The model obtained allows for discussion of the explanatory value of these socio-cognitive variables. 相似文献

Physical pain (induced by tissue damage) and psychological pain (induced by surprising incentive loss) share a set of common neural substrates, but little is known about their interactions. The present research studied such interactions using the formalin test to induce physical pain and consummatory successive negative contrast (cSNC) to induce psychological pain. In the formalin test, animals receive an intradermal injection of formalin (1%) in a hind paw. In cSNC, rats with free access to 32% sucrose show a sharp suppression of drinking behavior after a downshift to 4% sucrose, compared to rats that always receive 4% sucrose. In Experiment 1, formalin administration before the first and second 32-to-4% sucrose downshift trials enhanced cSNC. In Experiment 2, a similar treatment before the first downshift trial after a 16-to-4% sucrose downshift, which normally produces little or no evidence of cSNC, significantly increased cSNC. In Experiment 3, using a 32-to-4% sucrose downshift procedure similar to that of Experiment 1, no effects were observed following formalin administration immediately after Trial 11. Thus, no evidence was found that the effects of physical pain on cSNC were caused by changes in memory consolidation. The procedures used in these experiments offer a new approach to study the neural substrates of interactions between physical and psychological pain. 相似文献

Memory persistence needs a new event of consolidation 12h after the acquisition. We investigated the role of the cholinergic activity on the persistence of memory. For this purpose, we performed the treatments 9 or 12h after acquisition and the memory tested 2 or 7 days after inhibitory avoidance (IA) training. Here we report that activity of medial septum, by transitorily inactivating this structure with lidocaine 12h after IA training, is essential for memory persistence at the 7th day, but not for the formation at the 2nd day. We also report that muscarinic and nicotinic cholinergic receptors of CA1 area are engaged on memory persistence. Since scopolamine (mAChRs antagonist) and mecamylamine (nAChRs blocker) infusions, 12h post-training, demonstrated impairment on long term memory (LTM), persistence on the 7th day but no effect on LTM formation was found on the 2nd day in the IA test. The same effects were found with pirenzepine, an M1 antagonist. No effects on the formation and persistence of memory on the 2nd and 7th days were demonstrated after DHβE infusions (nAChRs subtype antagonist α4β2, α3β2). These findings suggest that mAChR and nAChR at the CA1 area, and also MS activation, are required for the persistence of memory. 相似文献
