In this article, the authors examine whether and how robot caregivers can contribute to the welfare of children with various cognitive and physical impairments by expanding recreational opportunities for these children. The capabilities approach is used as a basis for informing the relevant discussion. Though important in its own right, having the opportunity to play is essential to the development of other capabilities central to human flourishing. Drawing from empirical studies, the authors show that the use of various types of robots has already helped some children with impairments. Recognizing the potential ethical pitfalls of robot caregiver intervention, however, the authors examine these concerns and conclude that an appropriately designed robot caregiver has the potential to contribute positively to the development of the capability to play while also enhancing the ability of human caregivers to understand and interact with care recipients. 相似文献

Drawing on Intergroup Emotions Theory [Mackie, D. M., Maitner, A. T., & Smith, E. R. (in press). Intergroup emotions theory. In T.D. Nelson (Ed.), Handbook of Prejudice, Stereotyping, and Discrimination, New York: Erlbaum.], we propose that a perceiver’s emotional reactions toward other social groups can change in response to situationally induced shifts in self-categorization. American students were led to self-categorize as Americans or as students and reported their anger and respect towards Muslims and police. Results indicated that in reaction to Muslims, participants felt more anger and less respect when categorized as Americans than when categorized as students. In reaction to police, participants felt less anger and more respect when categorized as Americans than when categorized as students. These results support and extend IET, and suggest that in addition to prejudice reduction interventions that focus on recategorization of the target, perceiver recategorization of the self is a viable means of changing emotional reactions to social targets. 相似文献

The effects of spatial compatibility and spatial congruence have both been explained in terms of a dual-route model under which spatial information about the stimulus, regardless of task relevance, is directly passed from perception to action. Recently, however, some alternatives to the dual-route model of the Simon Effect have been proposed (or re-introduced) as viable explanations. The present experiment compared the magnitudes of the effects of spatial compatibility and spatial congruence across a range of tasks that varied in their dimensional overlap. The results exhibited a remarkable parallel between the two phenomena when viewed only in terms of the interaction between stimulus set and response set. This could be taken as new evidence for a common origin. However, when the entire pattern of results was examined, a large difference between compatibility and congruence were also seen, which implies that there is at least one important difference between the two phenomena. 相似文献

Emotions are increasingly being recognised as important aspects of prejudice and intergroup behaviour. Specifically, emotional mediators play a key role in the process by which intergroup contact reduces prejudice towards outgroups. However, which particular emotions are most important for prejudice reduction, as well as the consistency and generality of emotion–prejudice relations across different in-group–out-group relations, remain uncertain. To address these issues, in Study 1 we examined six distinct positive and negative emotions as mediators of the contact–prejudice relations using representative samples of U.S. White, Black, and Asian American respondents (N?=?639). Admiration and anger (but not other emotions) were significant mediators of the effects of previous contact on prejudice, consistently across different perceiver and target ethnic groups. Study 2 examined the same relations with student participants and gay men as the out-group. Admiration and disgust mediated the effect of past contact on attitude. The findings confirm that not only negative emotions (anger or disgust, based on the specific types of threat perceived to be posed by an out-group), but also positive, status- and esteem-related emotions (admiration) mediate effects of contact on prejudice, robustly across several different respondent and target groups. 相似文献

Life hassles have been implicated in both the formation and maintenance of psychosis symptoms. However, little is understood about the mechanism through which these stressors impact on psychosis. The current study proposed experiential avoidance (EA), a psychological coping style that is a central focus for change in Acceptance and Commitment Therapy (ACT), as a potential mediator of the link between life hassles and both the emergence and maintenance of delusional ideation. Participants were recruited to a non-clinical sample (N = 133) and a clinical sample of psychosis patients (N = 100). All participants completed a self-report questionnaire including a measure of delusions and delusional distress (Peters Delusions Inventory), life hassles (Survey of Recent Life Experiences) and EA (Acceptance and Action Questionnaire-II). Mediation testing (bootstrapping) indicated a significant mediation effect of EA in the relationship between life hassles and both delusions and delusional distress, in both clinical and non-clinical samples. The findings suggest that individuals (irrespective of their diagnostic status) with a tendency to suppress or avoid unwanted thoughts are significantly more likely to experience distressing delusions in response to stressful life occurrences. The use of ACT and Cognitive Behavioural Therapy to reduce EA in those at risk of emerging delusions and in patients with an already established psychosis is discussed. 相似文献

Most studies using the psychological refractory period (PRP) design suggest that dual-task performance is limited by a central bottleneck. Because subjects are usually told to emphasize Task 1, however, the bottleneck might reflect a strategic choice rather than a structural limitation. To evaluate the possibility that central operations can proceed in parallel, albeit with capacity limitations, we conducted two dual-task experiments with equal task emphasis. In both experiments, subjects tended to either group responses together or respond to one task well before the other. In addition, stimulus-response compatibility effects were roughly constant across stimulus onset asynchronies (SOAs). At the short SOA, compatibility effects also carried over onto response times for the other task. This pattern of results is difficult to reconcile with the possibility that subjects share capacity roughly equally between simultaneous central operations. However, this pattern is consistent with the existence of a structural central bottleneck. 相似文献

Robots are becoming an increasingly pervasive feature of our personal lives. As a result, there is growing importance placed on examining what constitutes appropriate behavior when they interact with human beings. In this paper, we discuss whether companion robots should be permitted to “nudge” their human users in the direction of being “more ethical”. More specifically, we use Rawlsian principles of justice to illustrate how robots might nurture “socially just” tendencies in their human counterparts. Designing technological artifacts in such a way to influence human behavior is already well-established but merely because the practice is commonplace does not necessarily resolve the ethical issues associated with its implementation. 相似文献

Target selection during bimanual reaching to direct cues is unaffected by the perceptual similarity of the targets 总被引:1,自引:0,他引:1

Investigations of bimanual movements have shed considerable insight on the constraints underlying our ability to perform coordinated actions. One prominent limitation is evident when people are required to produce reaching movements in which the two trajectories are of different amplitudes and/or directions. This effect, however, is only obtained when the movements are cued symbolically (e.g., letters indicate target locations); these planning costs are absent when the target locations are directly cued (J. Diedrichsen, E. Hazeltine, S. Kennerley, & R. B. Ivry, 2001). The present experiments test whether the absence of planning costs under the latter condition is due to the perceptual similarity of the direct cues. The results demonstrate that measures of response planning and execution do not depend on the perceptual similarity of the direct cues. Limitations in our ability to perform distinct actions with the two hands appear to reflect interactions related to response selection involving the translation of symbolic cues into their associated movements rather than arise from interactions associated with perception, motor programming, and motor execution. 相似文献
