The present research utilizes the information‐motivation‐behavioral skills (IMB) model (Fisher & Fisher, 1992, 2000) to predict breast self‐examination (BSE) and related behaviors in women. Results from a cross‐sectional survey study of 166 women found deficiencies in BSE‐related information, motivation, and behavioral skills, as well as insufficient rates of BSE‐related behaviors. Structural equation modeling indicated that IMB model variables account for significant variance in BSE and BSE‐related behaviors, and that the predicted relationships between the constructs of the 1MB model were supported. The present research extends the utility of the IMB model beyond preventive behaviors such as HIV prevention into the domain of detection behaviors such as BSE.  相似文献

In this paper I argue for modesty concerning what theoretical reason can accomplish in the moral dilemmas debate. Specifically, I contend that philosophers' conclusions for or against moral dilemmas are driven less by rational argument and more by how the moral world intuitively appears to them.I support this thesis by first considering an argument against moral dilemmas, the argument from deontic logic, and showing that its persuasive force depends on one's having already accepted its conclusion. I then make a different, and general, case that any argument in the moral dilemmas debate concerning the defeasibility of conflicting obligations can be marginalized by making not-unreasonable adjustments in the conditions for wrongdoing.These two strands of argument are related by the notion of inescapable wrongdoing. It is our standing intuitions about inescapable wrongdoing which make the relevant deontic logical principles plausible or implausible to us. And whether wrongdoing can be inescapable is central to deciding what the conditions for wrongdoing are. My conclusion is that the arguments in the moral dilemmas debate merely implement whatever standing intuition we have concerning inescapable wrongdoing, and that apart from any such intuition the arguments are unpersuasive.  相似文献

The Problem with Reid's Direct Realism   总被引:1,自引:0,他引:1  
There is a problem about the compatibility of Reid's commitment to both a sign theory of sensations and also direct realism. I show that Reid is committed to three different senses of the claim that mind-independent bodies and their qualities are among the immediate objects of perception, and I then argue that Reid's sign theory conflicts with one of these. I conclude by advocating one proposal for reconciling Reid's claims, deferring a thorough development and defence of the proposal to another paper.  相似文献

For most of the past century, philosophers on the Continent and those in the United States and Britain have taken themselves to be working in very different, even mutually exclusive, philosophical traditions. Although that may have been true until recently, it is no longer so. This piece surveys ten different proposed distinctions that have been offered between the two traditions, and it shows that none of them works, as there are major thinkers on both sides of each proposed distinction that do not neatly fit the proposal. The upshot of this is that it no longer makes sense to uphold the idea of two traditions, and that it is time we all dropped the mutual suspicion and denigration that have characterized relationships between us for the past hundred years.  相似文献

Blocking is a classical conditioning task in which prior training to one cue such as a tone reduces learning about a second cue such as a light, when subsequently trained as a tone-light compound. Blocking has been theorized to come about through a US-modulated error correction mechanism by Rescorla & Wagner (1972) as well as through a mechanism of learned inattention as theorized by Mackintosh (1973). In the case of eyeblink conditioning, an error correction mechanism has been hypothesized to take place in the cerebellum while some form of inattention has been hypothesized to take place in the hippocampal region. The hypothesis we are testing is whether the mechanism of learned inattention is involved in blocking in rabbit eyeblink conditioning. If blocking in eyeblink conditioning is produced by a mechanism of learned inattention, then training to a previously blocked cue should be slower than training to that cue in a na?ve animal. Rabbits that had received tone training followed by tone-light training exhibited blocking. Rabbits that had been previously blocked to the light acquired conditioned responses to the light at the same rate as naive rabbits. This finding failed to support the hypothesis that blocking in rabbit eyeblink conditioning is due to learned inattention, but does support the Rescorla-Wagner mechanism of error correction. The present finding along with previous work on error correction mechanism in the cerebellar-brainstem circuit (Kim et al., 1998) lend support to the theory that blocking, at least in rabbit eyeblink conditioning, seems to be due to an error correction mechanism rather than a learned inattention mechanism.  相似文献

Creativity is a complex construct that is conceptualized and measured in multiple ways. This study examined the relationship between creativity and personality taking this into account. It was hypothesized that applying different conceptions and measures would cause variation in the creativity–personality relationship. The participants (N = 224) were undergraduate students and completed six creativity measures, a personality inventory, and a demographic questionnaire. Personality predicted more creative production (R2 = .277) than creative potential (R2 = .176) and more self‐reported creativity (R2 = .348) than that which was externally rated (R2 = .149). Openness was most consistently and strongly related to creativity, but other personality factors varied in their influence and some demonstrated suppression effects. Overall, the results suggest that despite relatively small effects of personality on creativity, there appear to be meaningful differences in the relationships depending on conception and measurement. Implications for educational settings and future research are discussed.  相似文献

This paper examines the contrast and distinction between divergent and convergent scientific creativity, and the paradoxical relationship of scientific creativity with cultural factors in elementary students. With a newly developed measure of potential for scientific creativity, EPoC Science (Lubart et al., in press), students produce ideas in response to scientific problems, and both divergent‐exploratory as well as convergent‐integrative processes involved in scientific creativity are analyzed. An empirical study (n = 118) was conducted in France with elementary school children (ages 7–10). The divergent‐exploratory task was scored for fluency and statistical uniqueness. For the convergent‐integrative task, the number of concepts that a student integrated and synthesized, and the originality of the synthesis were scored. Results showed that divergent and convergent task performances were weakly related to each other. This suggests that divergence and convergence are two relatively distinct processes for scientific creativity, and that the relation is more complex than commonly assumed. In terms of culture‐related variables, immigrant cultural background (number of family members born outside of France) was significantly and negatively correlated with the originality of divergent and convergent scientific creativity. Findings are discussed and educational implications are proposed.  相似文献

We assessed and reduced the tardiness of 4 direct‐care staff employed at a school that provides educational services to children with autism. The Performance Diagnostic Checklist – Human Services was administered to participants and their supervisors to identify one or more indicated interventions. Relative to baseline, tardiness was lower during intervention. The most effective intervention included task clarification, a problem‐solving discussion, tokens exchangeable for back‐up reinforcers, and weekly graphic feedback. Moreover, participants reported that the intervention components, particularly praise and a token, had high acceptability.  相似文献

Research in International Relations (IR) frequently confronts claims about the emotions shared by members of a group. While much attention has been devoted to the potential for affective and emotional experience beyond the individual level, IR scholars have said less about the politics of invoking popular emotion. This article addresses that gap. Specifically, we argue that between individual—and even shared—affective experience on the one hand and group‐based “popular emotion” on the other exists not mechanisms of aggregation but rather processes of framing, projection, and propagation that are deeply political. We distinguish between two tropes that commonly structure references to popular emotion: communal emotion, the idealized attribution of an authentic, unifying emotional response of “the people,” and mass emotion, a volatile and potentially dangerous mob‐like reaction, but one also susceptible to manipulation. Using the outbreak of World War I as a showcase, we demonstrate the political significance of popular emotion, including its enduring relevance for understanding contemporary populism.  相似文献
