Switching between two tasks afforded by the same stimuli results in slower reactions and more errors on the first stimulus after the task changes. This “switch cost” is reduced, but not usually eliminated, by the opportunity to prepare for a task switch. While there is agreement that this preparation effect indexes a control process performed before the stimulus, the “residual” cost has been attributed to several sources: to a control process essential for task-set reconfiguration that can be carried out only after the stimulus onset, to probabilistic failure to engage in preparation prior to the stimulus, and to two kinds of priming from previous trials: positive priming of the now-irrelevant task set and inhibition of the now-relevant task-set. The main evidence for the carry-over of inhibition is the observation that it is easier to switch from the stronger to the weaker of a pair of tasks afforded by the stimulus than vice versa. We survey available data on interactions between task switching and three manipulations of relative task strength: pre-experimental experience, stimulus-response compatibility, and intra-experimental practice. We conclude that it is far from universally true that it is easier to switch to the weaker task. Either inhibition of the stronger task-set is a strategy used only in the special case of extreme inequality in strength, or its consequences for later performance may be masked by slower post-stimulus control operations for more complex tasks. Inhibitory priming may also be stimulus specific. Received: 31 March 1999 / Accepted: 23 July 1999  相似文献

Materialistic strivings have been implicated as a cause of unhappiness. Gratitude, on the other hand – both in its manifestations as a chronic affective trait and as a more temporary emotional experience – may be a cause of happiness. In the present paper we review the empirical research on the relationships among materialism, gratitude, and well-being. We present new correlational data on the gratitude–materialism relationship and propose that gratitude may have the potential to reduce materialistic strivings and consequently diminish the negative effects of materialistic strivings on psychological well-being. We conclude with some recommendations for future research on the relationships among gratitude, materialism, and well-being.  相似文献

Is the startle reaction an emotion?   总被引:1,自引:0,他引:1  
In this study, we examined startle reactions in which the subjects did and did not know when a blank pistol would be fired. In addition, we asked subjects to suppress their startle response and to simulate a startle when there was no gunshot. Detailed measurement of facial muscular actions supported most of the findings reported by Landis and Hunt (1939), but our findings suggested that startle be considered a reflex not an emotion. The findings are considered in terms of current disagreements about exactly what constitutes an emotion, including the argument between Zajonc (1980) and Lazarus (1984) about the role of appraisal.  相似文献

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.  相似文献

This brief article is concerned with an aspect of Jonathan Glover's book, Alien Landscapes?. After reflecting a little on the book as a whole, the question that is taken up is, ‘Why might a book that seeks to help those without mental disorders understand what they are like “from the inside” be of interest to laymen and practitioners in the criminal law?’. One answer lies in part in the way that ‘what it is like from the inside’ might interact with judgements of criminal responsibility. Taking its cue from examples used by Glover the article considers, and puts pressure on, the ‘dual view’ he proposes: that when dealing with those with mental disorders we should treat them as responsible agents in the sense of not withholding from them Strawson's ‘reactive attitudes’, while nevertheless accepting that their personalities and behaviours are the results of large doses of ‘bad luck’.  相似文献

Do the oppressed have an epistemic advantage when it comes to knowing about the systems that oppress them? If so, what explains this advantage? In this paper, I consider whether an epistemic advantage can be derived from the oppressed's contingent tendency to have more relevant experiences and motivation than the non-oppressed; or, alternatively, whether an advantage derives from the oppressed's very lived experience, thus being in principle unavailable to the non-oppressed. I then explore the potential role of knowledge-how for explaining an epistemic advantage. Ultimately, I conclude that the oppressed tend to have a contingent advantage, while rejecting that they have one in principle, except for when their phenomenological experience has an effect on the veracity of the claims they make. This has the important upshot that privileged people are not epistemically disadvantaged in principle and are thus often blameworthy for their ignorance about oppression.  相似文献

The social psychological literature considers two main perspectives on the study of perceived cultural differences between majorities and minorities: one proposes that perception of cultural differences is an antecedent of prejudice and another states that the attribution of cultural differences to minorities is already a hidden expression of racial prejudice. This paper offers further support to this latter perspective. One hundred and ninety-four participants answered a questionnaire measuring (1) general racist belief; (2) cultural differences attributed to Black people (hetero-ethnicization); (3) the asymmetric attribution of secondary and primary emotions to the in-group and to Black people (infra-humanization); (4) the asymmetric attribution of natural and cultural traits to in-group members and to Black people (ontologization); and (5) negative evaluation of this social category. The general racist belief scale was not anchored in a specific group and measured the belief in the inferiority of certain social groups or peoples based on biological or cultural factors. Relationships between the scales were analysed through a set of Structural Equation Models. According to the predictions, results showed that the attribution of cultural differences is a dimension of prejudice. Results also showed that attribution of cultural differences, negative evaluation of Black people, ontologization, and infra-humanization were different dimensions of a common latent factor that can be identified as racial prejudice; and that prejudice was predicted by general racist belief. Results are discussed in the light of the study of the impact of perceived cultural differences on intergroup relations and in the light of the "new racism" approaches.  相似文献

There are two widely held views in the literature as regards Wittgenstein's philosophy. One says that Wittgenstein in his later work appeals to ordinary language in his effort to show how the philosophical problems can be dissolved, and the other says that his investigation is a grammatical one. This paper undertakes to examine what is meant by a grammatical investigation, especially in view of the fact that this investigation relies on empirical facts that have to do with linguistic usage. The examination is carried out by concentrating on what Wittgenstein has to say on the issue of knowledge – in particular, how the way we use the word contributes to the dismissal of Moore's answer to the challenge of scepticism. The conclusion is that Wittgenstein's resort to ordinary language is not typically empirical. The examples of ordinary usage that he cites may be contingent, but they could not have been different given the language games they are part of. The correct use of words Wittgenstein appeals to is not fixed by some kind of essence, but neither is it decided by a majority rule. It gets entrenched in a complex nexus of practices. Wittgenstein's reference to "use" instead of 'usage"and to "linguistic facts" instead of "sociological facts" lends support more to a logical than to an empirical investigation.  相似文献

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.  相似文献

Re-reading is the most common learning strategy, albeit not a very efficient one. Testing is highly efficient, but not perceived by students as a learning strategy. Prospective judgment-of-learning (JOL) reflect the learner's impression of subsequently being able to retrieve the ongoing learning in a cued-recall task. Estimating JOL involves attempting to retrieve the information, as in testing. The few studies that have explored the potential mnemonic benefit of JOL have yielded contradictory results. Our aim was to compare JOL and testing with re-study and to examine the impact of these strategies according to the relative difficulty of the material (cue-target association strength) in two experiments. After a first encoding phase, participants re-studied, provided JOL, or took a test. Forty-eight hours later, they participated in a final cued-recall test, during which their confidence level judgments were collected. The main result was that delayed JOL behaved in the same way as testing, and both yielded better performances than re-study when material was of moderate difficulty. The easy or very difficult material revealed no differences between these strategies. JOL is proposed as an alternative to testing when faced with difficult material.  相似文献

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.  相似文献

I argue in this paper two theses. First, I argue that the internal consistency of the argument from evil demands that it take into account some form of EST. Thus, there is no ground for the atheist to chide the theist when the theist appeals to an expanded version of theism. Second, I show that it isprima facie probable that RST does in fact ential EST. I show this by capitalizing on the distinction between what is contained in a concept and what is entailed by a concept. What a term or concept means is different from what it may entail. What a concept or term entails is conceptually more robust than what it simply means. I call this the “containment objection” and if is true, then the restricted conjunction rule cannot apply since a version of theism sufficient to deflate the evidential argument would not be logically independent from RST,pace Rowe.  相似文献

The primary focus of this article is to examine the general assumption that families are left largely unchanged by their participation in research, and to question whether family research can have unintended positive or negative effects on participants. The present article reports feedback from families participating in the Nonshared Environment and Adolescent Development project, a longitudinal study of family process and adolescent development. Families differed in their perceptions about whether the research experience was positive, detrimental, or inconsequential. This feedback underscores the researcher's ethical responsibility to detect and remove deleterious effects of participation. Suggestions are made for providing adequate debriefing to subjects and for using debriefing as a research tool to study the interaction between researcher and families.  相似文献

Antiques are undoubtedly objects worthy of aesthetic appreciation, but do they have a distinctive aesthetic value in virtue of being antiques? In this article we give an account of what it is to be an antique that gives the thesis that they do have a distinctive aesthetic value a chance of being true and suggests what that distinctive value consists in. After introducing our topic in Section I, in Section II we develop and defend the Adjectival Thesis: the thesis that the concept of being an antique is an adjectival concept. This provides us with the means to formulate our definition, which we do in Section III. In Section IV we further explicate and defend our definition. In Section V we conclude by briefly saying where we think our definition could be improved, by making a few comments about the aesthetics of antiques and by stating an interesting consequence of our definition: that it is not analytic that antiques are old.  相似文献

Neither logical deduction nor empirical induction is capable of mediating the dispute between religious disciples and non-disciples. The case is particularly acute when it comes to the divine Reality (God). Within Wittgenstein’s theoretical framework, some scholars start from the perspective of language games, contending that this dispute is meaningless and should be abandoned, while others are not satisfied with such a settlement and extend Wittgenstein’s aspect theory to religious issues, arguing that God is an aspect. The extension includes analogous and theoretical extensions. This article will show that even if these two extensions are successful, their interpretations with regard to the disputes between religious disciples and non-disciples are not convincing. Worse still, the extension from aspect theory to religious issues is by no means successful in proving that God is an aspect.  相似文献

What should and should not be considered an affordance is still an open issue. At the 2002 North American meeting of the International Society for Ecological Psychology, a symposium was held concerning this topic. The articles in this special issue are expanded versions of the papers presented at that symposium. To set the stage for those discussions, this article presents an analysis of the evolution of J. J. Gibson's thinking on this issue, from some of his earliest writings (i.e., J. J. Gibson & Crooks, 1938) through his most recent writings (i.e., J. J. Gibson, 1979/1986). It is hoped that this forum will stimulate thinking concerning this important ecological concept.  相似文献
