Theories of objects recognition, scene perception, and neural representation of scenes imply that jumbling a coherent scene should reduce change detection. However, evidence from the change detection literature questions whether jumbling affects change detection. The experiments reported here demonstrate that jumbling does, in fact, reduce change detection. In Experiments 1 and 2, change detection was better for normal scenes than for jumbled scenes. In Experiment 3, inversion failed to interfere with change detection, demonstrating that the disruption of surface and object continuity inherent to jumbling is responsible for reduced change detection. These findings provide a crucial commonality between change detection research and theories of scene perception and neural representation. We also discuss why previous research may have failed to find effects of jumbling. 相似文献

Nanotechnology is an important platform technology which will add new features like improved biocompatibility, smaller size,
and more sophisticated electronics to neuro-implants improving their therapeutic potential. Especially in view of possible
advantages for patients, research and development of nanotechnologically improved neuro implants is a moral obligation. However,
the development of brain implants by itself touches many ethical, social and legal issues, which also apply in a specific
way to devices enabled or improved by nanotechnology. For researchers developing nanotechnology such issues are rather distant
from their daily work in the lab, but as soon as they use their materials or devices in medical applications such as therapy
of brain diseases they have to be aware of and deal with them. This paper is intended to raise sensitivity for the ethical,
legal and social aspects (ELSA) involved in applying nanotechnology in brain implants or other devices by highlighting the
short term problems of testing and clinical trials within the existing regulatory frameworks (A), the short and medium-term
questions of risks in the application of the devices (B) and the long-term perspectives related to problems of enhancement
(C). To identify and address such issues properly nanotechnologists should involve ethical, legal and social experts and regulatory
bodies in their research as early as possible. This will help to remove pressure from regulatory bodies, to settle public
concern and to prevent non-acceptable developments for the benefit of the patients.

The theme of this symposium is distinctive and challenging, because it incorporates the dimensions of interreligious reflection, theology, science, and ethics. This article presents a palette of issues that are both challenge and resource for approaching the theme. Three sets of issues are considered: (1) the role of religion in culture, (2) theological interpretation of nature, disease, and evil, and (3) the fashioning of a global ethic. 相似文献

A longitudinal study was conducted among 93 nurses to determine the role of comparing one’s performance with that of one’s colleagues in the increase versus decrease of perceived relative deprivation at work over a period of one year. Relative deprivation at T2 had increased particularly among those high in social comparison orientation (Gibbons & Buunk, 1999) who at T1 (1) more frequently engaged in upward comparisons; (2) more frequently derived positive as well as negative feelings from such comparisons; and (3) more frequently derived negative feelings from downward comparison. Moreover, engaging in downward comparison also led to an increase in perceived relative deprivation at T2. This study is one of the few to find evidence for longitudinal effects of social comparison activity, and the first to find that such effects occur only for those high in social comparison orientation. 相似文献

This study provides a new perspective on the relationship between LMX and affective organizational commitment, treating person-organization fit (P-O fit) as an explanatory mechanism and identifying co-worker support and customer recognition as moderators of the first stage of this indirect relationship. Results of a three-wave time-lagged study of survey responses obtained from 137 employees working in the retail service sector over a three-year period were consistent with the proposed model. Multiple regression and moderated mediation analyses revealed that LMX indirectly and positively predicted affective organizational commitment through its positive relationship with P–O fit, suggesting that LMX provides a means by which supervisors are able to instill organizational values in employees and/or signal the degree to which their values match those of the organization. Moreover, co-worker support and customer recognition each moderated the first stage of this indirect relationship, such that the relationship between LMX and P–O fit and, in turn, its indirect relationship with affective organizational commitment is stronger as support from co-workers or customer recognition is lacking. At high levels of co-worker support and customer recognition, LMX exhibits no significant relationship with P–O fit. Together, these results provide new explanations for how and under which conditions LMX might influence employee commitment, suggesting that LMX is particularly salient when employees are lacking other sources of relational support or recognition and that high-quality relations with co-workers and/or customers may serve to compensate for low LMX quality in shaping P–O fit and affective organizational commitment. 相似文献

The author considers the infl uences that different psychoanalytic trends have had on the thought processes of psychoanalysts in the River Plate region. She begins by giving a history of the way in which these trends were shaped by the sociocultural context of the region, and of how the dialectical relationship between these two factors produced the River Plate region's (Argentina and Uruguay) own theoretical model. The author includes a study‐albeit incomplete‐of major local developments, and attempts to defi ne the characteristics of a regional model. The model is based on the following parameters: the fundamental rules of evenly suspended attention and free association; the technical frame; links between theory and clinical practice such as transference‐countertransference, resistance, identifi cation, the analytic fi eld; the concept of psychic change and its indicators; and the interpretive instrument. The author considers the past and present infl uence of Lacanian thought on this model. She concludes by reviewing some of these theoretical and clinical concepts. 相似文献

This study examined effects of variation in teacher organization on how time is spent in classrooms, focusing on time spent in transitions and instruction, including child skill by teacher organization interactions. Forty-four first-grade classrooms were observed three times over the school year. Timed narratives of each activity were recorded. “Orient-organize” referred to time teachers spent orienting students to classroom procedures or organizing the class for specific assignments, and included instructional clarity, where teachers described objectives of activities to students. Using hierarchical linear modeling, substantial variation across teachers in orient-organize was observed. Overall, classrooms spent less time in organization as the school year progressed. In addition, spending more time in organization was related to less time spent in transition. Students in classrooms that spent more time in organization in the fall also experienced greater amounts of time in child-managed activities in the spring. There was also an interaction between child vocabulary and amount of orient-organize in the winter. Students with lower vocabulary scores were more likely to be in classrooms that spent more time in spring child-managed activities if they continued to receive substantial amounts of orient-organize in the winter. The opposite was the case for students with high vocabulary skills. 相似文献

AbstractIn this paper, we explore the issue of the elimination of sports, or elements of sports, that present a high risk of brain injury. In particular, we critically examine two elements of Angelo Corlett’s and Pam Sailors’ arguments for the prohibition of football and Nicholas Dixon’s claim for the reformation of boxing to eliminate blows to the head based on (a) the empirical assumption of an essential or causal connection between brain injuries incurred in football and the development of a degenerative brain disease known as chronic traumatic encephalopathy (CTE); and (b) John Stuart Mill’s rejection of consensual domination (ie voluntary enslavement). We present four arguments to contest the validity of Corlett, Dixon’s and Sailor’s positions. Specifically, we argue that (i) certain autonomy-based arguments undermine paternalist arguments for reform; (ii) the nature of the goods people pursue in their lives might justify their foregoing (degrees of) future autonomy; (iii) Mill’s argument against consensual domination draws on ambiguous and arbitrary distinctions; (iv) the lack of consensus and empirical evidence regarding CTE arising from brain injuries in sport underdetermines calls for reform. We conclude that these proposals for reforming or eliminating sports with high risks of brain injuries are not well founded. 相似文献

AbstractAfter years of skepticism and denials regarding the significance of concussions in sport, the issue is now front and center. This is fitting, given that the impact of concussions in sport is profound. Thus, it is with trepidation that one ventures to direct some attention onto brain injuries other than concussions incurred through sport. Given a closer look, however, it may be that considering various kinds of brain injuries, with different causes, will help us better understand the range and seriousness of brain injuries in sport. My focus is on emotional trauma in sport. I argue that severe emotional pathology is evidence of underlying brain injury. Any attempt to minimize the significance of emotional disturbance that results from emotional trauma as ‘merely’ psychological in nature is thus misguided. 相似文献
