When multiple objects are presented briefly and simultaneously in a visual array, visual short-term memory (VSTM) can maintain only a limited number of these items. The present research report reveals that splitting the to-be-remembered items into two sequential arrays significantly increases VSTM performance relative to the simultaneous presentation of the same items. A memory benefit also emerges when the full object array is flashed twice (repeated) rather than being presented continuously for the same duration. Moreover, the sequential and repetition benefits are specifically pronounced for individuals with low performance for simultaneously presented items. Our results suggest that the conventional, simultaneous presentation mode may underestimate VSTM performance due to attentional limitations and/or competition between stimulus representations. In contrast, temporal segregation of the stimulus input may help participants maximize their performance and utilize their full VSTM capacity.  相似文献

The decision to terminate a clinical trial earlier than planned is often described as ethically problematic, but it is rarely systematically analyzed as an ethical issue in its own right. This paper provides an overview of the main ethical considerations at stake in such decisions and of the main tensions between these considerations. Arguments about informed consent and the impact of early stopping on research and society are explored. We devote particular attention to a familiar conflict that arises with special urgency when early data suggest that the experimental treatment is superior. Should the trial be stopped so that participants in the control group will not be allocated a seemingly inferior treatment, or should it continue in pursuit of evidence conclusive enough to improve the care of future patients? We scrutinize three ways to address this problem. Rather than dissolving the tension, they represent different trade-offs between the respective welfare interests of subjects and future patients.  相似文献

Several studies have indicated that scientists are likely to have an outlook on both facts and values that are different to that of lay people in important ways. This is one significant reason it is currently believed that in order for scientists to exercise a reliable ethical reflection about their research it is necessary for them to engage in dialogue with other stakeholders. This paper reports on an exercise to encourage a group of scientists to reflect on ethical issues without the presence of external stakeholders. It reports on the use of a reflection process with scientists working in the area of animal disease genomics (mainly drawn from the EADGENE EC Network of Excellence). This reflection process was facilitated by using an ethical engagement framework, a modified version of the Ethical Matrix. As judged by two criteria, a qualitative assessment of the outcomes and the participants’ own assessment of the process, this independent reflective exercise was deemed to be successful. The discussions demonstrated a high level of complexity and depth, with participants demonstrating a clear perception of uncertainties and the context in which their research operates. Reflection on stakeholder views and values appeared to be embedded within the discussions. The finding from this exercise seems to indicate that even without the involvement of the wider stakeholder community, valuable reflection and worthwhile discourse can be generated from ethical reflection processes involving only scienitific project partners. Hence, the previous assumption that direct stakeholder engagement is necessary for ethical reflection does not appear to hold true in all cases; however, other reasons for involving a broad group of stakeholders relating to governance and social accountability of science remain.  相似文献

Religious leaders sometimes condemn progressive social norms. This article revisits David Hume's hypothesis that secular states can “bribe” churches into adopting less strict religious doctrines. The hypothesis is difficult to test due to reverse causality: more liberal theologies may attract more political support in the first place. The empirical strategy used to circumvent this problem focuses on a theological conflict over same‐sex marriage within the Church of Sweden and takes advantage of political regulations that effectively make some parishes shareholders of the church's state‐protected property. The shares used for statistical identification are tied to property rights assigned more than 300 years ago, and they cannot be sold, traded, or amended by the individual parishes. The results show that priests in shareholding parishes are less likely to publicly oppose same‐sex marriage. The impact of political protection is stronger in parishes with more conservative members. The results are consistent with a model of clerical opportunism, in which income protection makes priests less likely to pander to the stricter followers.  相似文献

When contesting for political office, leaders do not only seek to build their own following but also to engage in attacks to destabilize opponent leaders. However, research has yet to explore and explain the nature of attacks that seek to destabilize a leader's influence. Building on the identity leadership model which sees leadership as flowing from a leader's capacity to promote a sense of shared identity with followers, we argue that a leader can be destabilized if followers come to see the leader as defiling, devaluing, dividing, and destroying this shared sense of “us.” To explore these ideas, we analyzed the attack rhetoric used by Hillary Clinton and Donald Trump during the 2016 U.S. presidential debates to examine how they sought to subvert each other's leadership. Our analysis supports the proposed model and sheds light on the hitherto underexplored topic of leadership destabilization. Moreover, by helping us understand the ways in which principles of identity leadership can be weaponized to destabilize leadership, the analysis defines an important agenda for future research.  相似文献

Background. Student's temperament plays a significant role in teacher's perception of the student's learning style, educational competence (EC), and teachability. Hence, temperament contributes to student's academic achievement and teacher's subjective ratings of school grades. However, little is known about the effect of gender and teacher's age on this association. Aims. We examined the effect of teacher's and student's gender and teacher's age on teacher‐perceived temperament, EC, and teachability, and whether there is significant same gender or different gender association between teachers and students in this relationship. Sample. The participants were population‐based sample of 3,212 Finnish adolescents (M= 15.1 years) and 221 subject teachers. Methods. Temperament was assessed with Temperament Assessment Battery for Children – Revised and Revised Dimensions of Temperament Survey batteries and EC with three subscales covering Cognitive ability, Motivation, and Maturity. Data were analyzed with multi‐level modelling. Results. Teachers perceived boys’ temperament and EC more negatively than girls’. However, the differences between boys and girls were not as large when perceived by male teachers, as they were when perceived by female teachers. Males perceived boys more positively and more capable in EC and teachability than females. They were also stricter regarding their perceptions of girls’ traits. With increasing age, males perceived boys’ inhibition as higher and mood lower. Generally, the older the teacher, the more mature he/she perceived the student. Conclusions. Teachers’ ratings varied systematically by their gender and age, and by students’ gender. This bias may have an effect on school grades and needs be taken into consideration in teacher education.  相似文献

Being raised in the genomic era may not only increase knowledge of available genetic testing but may also have an impact on how genetic information is perceived. However, little is known about how current adolescents react to the language commonly used by health care professionals providing prenatal counseling. In addition, as risk communication is related to numbers and figures, having different educational backgrounds may be associated with variability in risk perceptions. In order to investigate these issues, a previously developed questionnaire studying different ways of being told about hypothetical anomalies in a baby and corresponding risks (Abramsky and Fletcher Prenatal Diagnosis 22(13):1188-1194, 2002) was administered to high-school students in Sweden. A total of 344 questionnaires were completed by students belonging to a natural science or a social science program. The data show that teenage participants found technical jargon and words such as rare and abnormal more worrying than the presented comparison terms. Negative framing effects and perception differences related to numeric risk formats were also present. Additionally, participants' gender and educational program did not seem to have an effect on risk assessment. In addition to reporting the questionnaire results, we discuss the ethical implications of the data based on the norm of non-directiveness and make some recommendations for practice. In general, genetic counselors should be aware that the language used within clinical services can be influential on this group of upcoming counselees.  相似文献
