We review Side Effects, a 2013 film involving bioethics, pharmaceuticals, and financial conspiracies. After the main character Emily unsuccessfully attempts suicide, she begins receiving care from a psychiatrist, Dr. Banks. Following numerous events, she is placed on a fictional antidepressant, Ablixa, which leads her to suffer from sleepwalking. During an episode of sleepwalking she commits a serious crime. The film poses an interesting dilemma: How responsible would the physician be in this instance? We analyze this question by applying numerous ethical principles.  相似文献

ObjectivesThe main purpose of the present investigation was to examine approach-avoidance achievement goal patterns across stages of physical activity participation. In addition, sex differences in the approach and avoidance goals were examined as well as goal contrast scores (i.e., approach minus avoidance) as secondary purposes.DesignThe research was cross-sectional in design.MethodParticipants were 804 university students who completed a questionnaire assessing their stage of physical activity, 2 × 2 achievement goals, and demographics.ResultsMANOVA results revealed hypothesized and significant (p < .001) physical activity stage differences in the mastery and performance approach goals as well as significant (p's < .05) gender differences in both performance goals. A significant (p < .01) gender by physical activity stage interaction emerged for the performance goals and surprisingly, was found mainly in the advanced exercise stages (i.e., action, maintenance, and long-term maintenance). Last, significant (p < .001) gender and physical activity stage main effects emerged for the achievement goal contrasts. Males endorsed both the mastery and performance contrasts more than females. Collapsed for both sexes, the contrast scores were greater in the physically active than the non-active stages.ConclusionsFindings suggested that interventions targeting physical activity in university students should emphasize approach goals relative to the avoidance goals. Particular attention should be paid to the performance goals in the maintenance and long-term maintenance stages as they appeared theoretically inconsistent for the female participants. Last, the split in the preparation stage (active, non-active) should be incorporated into future stage based investigations as the split demonstrated two meaningfully different subgroups.  相似文献

The Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus.  相似文献

In visual search tasks, spatial attention selects the locations containing a target or a distractor with one of the target's features, implying that spatial attention is driven by target features (M.S. Kim & K. R. Cave, 1995). The authors measured the effects of location-based grouping processes in visual search. In searches for a color-shape combination (conjunction search), spatial probes indicated that a cluster of same-color or same-shape elements surrounding the target were grouped and selected together. However, in searches for a shape target (feature search), evidence for grouping by an irrelevant feature dimension was weaker or nonexistent. Grouping processes aided search for a visual target by selecting groups of locations that shared a common feature, although there was little or no grouping by an irrelevant feature when the target was defined by a unique salient feature.  相似文献

Being able to judge the fairness of a personal encounter and having an appreciation of the associated feelings are important components of prosocial development. This study explored a common feature of everyday experience: unfair reward and unfair punishment. Scenarios depicting 4 possible variants of unfairness were read to children aged 9 to 11 years, who then made judgments regarding the degree of unfairness and the nature and strength of the feelings experienced by the characters. Our hypothesis that children with classroom conduct problems would judge the non-receipt of a deserved reward as worse than the receipt of an undeserved punishment was not confirmed. This differentiation, however, did prove to be characteristic of boys in general, but not girls. Being asked to think of unfair things that had actually happened did not appear to influence the children's responses to hypothetical unfair situations, but did reveal that children experience and remember a variety of unfair events in everyday family contexts. This study provides evidence that children actively monitor the receipt of social reward and punishment according to their perception of fairness.  相似文献

While cognitive behavioral approaches have been shown to help some individuals with schizophrenia, these approaches may be limited when working with patients with impairments in the metacognitive abilities required to form complex and integrated representations of themselves and others. In response, this paper explores the possibility that a key to working with patients with relatively impaired self-reflectivity lies in explicitly focusing on a patient’s intersubjective experience within psychotherapy. We offer theoretical and empirical support for the assertion that the tolerance and capacity for intersubjectivity is a basis for the development of self-reflectivity in general. We also explore how the fostering of intersubjective processes in psychotherapy might enable some patients to form more complex ideas about themselves and so better ward off delusions in the face of the challenges of daily life. To illustrate these principles we present the case of a patient with tenaciously held delusions and limited capacity for self-reflection. We discuss when and how the therapist’s awareness and verbalization of intersubjective processes within session allowed her and the patient to develop more complex and consensually valid ideas about him as a being in the world, which then assisted the patient to achieve improvements in a number of domains in his life.  相似文献

ABSTRACT

Children tend to select a novel object rather than a familiar object when asked to identify the referent of a novel label. Current accounts of this so-called disambiguation effect do not address whether children have a general metacognitive representation of this way of determining the reference of novel labels. In two experiments (each N = 48), three- and four-year-olds received a prediction task that required such a representation. In the initial phase, children completed four disambiguation test trials that were presented as instances of the same “game.” In the next phase, they received four additional trials. These differed only in that before the label was presented, children were asked to predict which object “was going to be right.” On the first prediction trial, most four-year-olds predicted the novel object, whereas most three-year-olds did not. On subsequent trials, despite having received feedback regarding predictions, three-year-olds showed no tendency to begin to predict the novel object, whereas most four-year-olds continued to make this prediction. These findings add to the evidence that most children develop a general metacognitive representation of their tendency to map novel labels onto novel rather than familiar objects some time around their fourth birthday.  相似文献

Generic statements about the abilities of children's social groups (e.g. ‘Girls/Boys are good at this game’) negatively impact children's performance – even if the statements are favorable towards children's own social groups. We explored the mechanism by which generic language impairs children's performance. Across three studies, our findings suggest that generic statements influence children's performance by creating an entity belief (i.e. a belief that a fixed ability determines performance). Children who were exposed to a generic statement about their social group's ability performed worse than children in control conditions. This effect hurt children's performance even when the person who made the generic statement was no longer present and a new person not privy to the statement replaced them. However, when children heard a generic statement paired with an effort explanation (i.e. ‘Girls/Boys are good at this game because they try really hard when they draw’) they performed better than children who heard the generic statement with no explanation (i.e. just ‘Girls/Boys are good at this game’) and children who heard the generic statement paired with a trait explanation (i.e. ‘Girls/Boys are good at this game because they are smart and really good at drawing’). This work uncovers when and how generic statements that refer to the ability of one's social group hinder performance, informing the development of practices to improve student motivation and learning.  相似文献

Wild animal reproduction poses an important moral problem for animal rights theorists. Many wild animals give birth to large numbers of uncared-for offspring, and thus child mortality rates are far higher in nature than they are among human beings. In light of this reproductive strategy – traditionally referred to as the ‘r-strategy’ – does concern for the interests of wild animals require us to intervene in nature? In this paper, I argue that animal rights theorists should embrace fallibility-constrained interventionism: the view that intervention in nature is desirable but should be constrained by our ignorance of the inner workings of ecosystems. Though authors sometimes assume that large-scale intervention requires turning nature into an enormous zoo, I suggest an alternative. With sufficient research, a new form of gene editing called CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) promises to one day give us the capacity to intervene without perpetually interfering with wild animals’ liberties.  相似文献

We examined whether two interpersonal processes, self-disclosure and affirmation of ideal self, mediated the relationship between cross-ethnic friendships and psychological well-being and academic outcomes. We conducted a cross-sectional survey with 484 secondary school children (243 White European, 241 South Asian British; Mage = 11.10, 220 boys, 264 girls) recruited from 35 multiethnic classrooms. Results of multilevel structural equation modeling revealed mediational effects of self-disclosure between cross-ethnic friendships and psychological well-being for only South Asian children. Affirmation also mediated the association between cross-ethnic friendships and both psychological well-being and academic outcomes for South Asian children. For White European children, affirmation mediated the association between cross-ethnic friendships and psychological well-being. Further analyses demonstrated that self-disclosure resulting from cross-ethnic friendship quality facilitated affirmation, which in turn promoted both sets of outcomes. Findings demonstrate that cross-ethnic friendships in multiethnic settings contribute to well-being through the generation of positive interpersonal processes.  相似文献
