ABSTRACTCOVID-19 is compromising all aspects of society, with devastating impacts on health, political, social, economic and educational spheres. A premium is being placed on scientific research as the source of possible solutions, with a situational imperative to carry out investigations at an accelerated rate. There is a major challenge not to neglect ethical standards, in a context where doing so may mean the difference between life and death. In this paper we offer a rubric for considering the ethical challenges in COVID-19 related research, in the form of an ethics toolkit for global research developed at the University of Edinburgh in collaboration with more than 200 global researchers from around the world. This toolkit provides a framework to support confrontation of ethical conflicts through the integrated and iterative analysis of Place, People, Principles and Precedents, throughout the research journey. Two case analyses are offered to exemplify the utility of the toolkit as a flexible and dynamic tool to promote ethical research in the context of COVID-19.  相似文献

In summary, educated, married women in their fifties generally appear to be happy regardless of their employment status, age, so-cioeconomic status, educational level, husband's attitude, life stressors, and menopausal symptoms. The empty nest transition does not seem to be anything near a universal problem for well-educated middle-aged women. It may, however, act as a "trigger event" for women with other significant problems, just as illness or retirement might trigger distress in some women. The empty nest transition does appear to be very important to women, but it seems that coping ability may be predictive of who will successfully deal with the adjustment. One implication of this finding for psychologists dealing with women in this stage is to teach general coping skills and apply them to specific problem areas relevant to this life stage such as empty nest, career decisions, retirement planning, health care, religion, recreation, and financial security.  相似文献

Pragmatic abilities are fundamental to successful language use and learning. Individual differences studies contribute to understanding the psychological processes involved in pragmatic reasoning. Small sample sizes, insufficient measurement tools, and a lack of theoretical precision have hindered progress, however. Three studies addressed these challenges in three- to 5-year-old German-speaking children (N = 228, 121 female). Studies 1 and 2 assessed the psychometric properties of six pragmatics tasks. Study 3 investigated relations among pragmatics tasks and between pragmatics and other cognitive abilities. The tasks were found to measure stable variation between individuals. Via a computational cognitive model, individual differences were traced back to a latent pragmatics construct. This presents the basis for understanding the relations between pragmatics and other cognitive abilities.

Research Highlights

  • Individual differences in pragmatic abilities are important to understanding variation in language development.
  • Research in this domain lacks a precise theoretical framework and psychometrically high-quality measures.
  • We present six tasks capturing a wide range of pragmatic abilities with excellent re-test reliability.
  • We use a computational cognitive model to provide a substantive theory of individual differences in pragmatic abilities.

We present an exact replication of Experiment 2 from Kovács and Mehler's 2009 study, which showed that 7-month-old infants who are raised bilingually exhibit a cognitive advantage. In the experiment, a sound cue, following an AAB or ABB pattern, predicted the appearance of a visual stimulus on the screen. The stimulus appeared on one side of the screen for nine trials and then switched to the other side. In the original experiment, both mono- and bilingual infants anticipated where the visual stimulus would appear during pre-switch trials. However, during post-switch trials, only bilingual children anticipated that the stimulus would appear on the other side of the screen. The authors took this as evidence of a cognitive advantage. Using the exact same materials in combination with novel analysis techniques (Bayesian analyses, mixed effects modeling and cluster based permutation analyses), we assessed the robustness of these findings in four babylabs (N = 98). Our results did not replicate the original findings: although anticipatory looks increased slightly during post-switch trials for both groups, bilingual infants were not better switchers than monolingual infants. After the original experiment, we presented additional trials to examine whether infants associated sound patterns with cued locations, for which we did not find any evidence either. The results highlight the importance of multicenter replications and more fine-grained statistical analyses to better understand child development.

Highlights

  • We carried out an exact replication across four baby labs of the high-impact study by Kovács and Mehler (2009).
  • We did not replicate the findings of the original study, calling into question the robustness of the claim that bilingual infants have enhanced cognitive abilities.
  • After the original experiment, we presented additional trials to examine whether infants correctly associated sound patterns with cued locations, for which we did not find any evidence.
  • The use of novel analysis techniques (Bayesian analyses, mixed effects modeling and cluster based permutation analyses) allowed us to draw better-informed conclusions.

Retrieval of proper names is a cause of concern and complaint among elderly adults and it is an early symptom of patients suffering from neurodegenerative diseases such as Alzheimer's disease (AD). While it is well established that AD patients have deficits of proper name retrieval, the nature of such impairment is not yet fully understood. Specifically, it is unknown whether this deficit is due to a degradation of the links between faces and proper names, or due to deficits in intentionally accessing and retrieving proper names from faces. Here, we aim to investigate the integrity of the links between famous faces and proper names in AD while minimizing the impact of the explicit retrieval. We compare the performances of AD patients and elderly controls in a face-name priming task. We assess the integrity of the link between faces and names at two different levels: identity level - the name and face belong to the same person; and semantic level - the name and face belong to the same category (e.g., politicians). Our results reveal that AD patients compared with controls show intact semantic priming but reduced priming for person identity. This suggests that the deficits in intentionally retrieving proper names in AD are the result of a partial disruption of the network at the identity level, i.e., the links between known faces and proper names.  相似文献
