How do children learn associations between novel words and complex perceptual displays? Using a visual preference procedure, the authors tested 12- and 19-month-olds to see whether the infants would associate a novel word with a complex 2-part object or with either of that object's parts, both of which were potentially objects in their own right and 1 of which was highly salient to infants. At both ages, children's visual fixation times during test were greater to the entire complex object than to the salient part (Experiment 1) or to the less salient part (Experiment 2)--when the original label was requested. Looking times to the objects were equal if a new label was requested or if neutral audio was used during training (Experiment 3). Thus, from 12 months of age, infants associate words with whole objects, even those that could potentially be construed as 2 separate objects and even if 1 of the parts is salient.  相似文献

Law enforcement officials have asked health care providers to evaluate patient applications for concealed weapon permits. The current study was designed to examine physician beliefs regarding competency to carry a concealed weapon for patients with specific physical and mental conditions. Among 222 North Carolina physicians who participated in this survey (40% response rate), large variation and uncertainty existed for determining competency. Physicians most frequently chose mild dementia, post-traumatic stress disorder, and recent depression as conditions that would render a patient not competent to carry a concealed weapon. Male physicians and those owning a gun were more likely to deem a patient competent. Almost a third of physicians were unsure about competence for most conditions. Physicians asked to assess competency of patients to carry a concealed weapon have quite disparate views on competency and little confidence in their decisions. If physicians are expected to assess patient competence to carry a concealed weapon, more objective criteria and training are needed. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

In studies of child development, the combined effect of multiple risks acting in unison has been represented in a variety of ways. This investigation builds upon this preceding work and presents a new procedure for capturing the combined effect of multiple risks. A representative sample of 2,899 British children had their cognitive development measured at 36 and 58 months of age along with 10 potential risks during this period of development. Comparing a cumulative index of these risks against the previously undocumented alternative of confirmatory factor analysis using formative measurement, this study found differences favouring the factor analysis. The factor analysis procedure demonstrated greater predictive power of children's cognitive development while it systematically tested two of the assumptions implicit in cumulative risk indices.  相似文献

This article discusses two views associated with narrative conceptions of the self. The first view asserts that our whole life is reasonably regarded as a single unit of meaning. A prominent strand of the philosophical narrative account of the self is the representative of this view. The second view—which has currency beyond the confines of the philosophical narrative account—is that the meaning of a life story is dependent on what happens at the end of it. The article argues that the connection between these two views is more tentative than often supposed: philosophical narrativists that see life as a single unit of value and meaning nonetheless provide grounds for arguing that the end of life is not the best and may be a particularly bad time to approach and intervene in the matter of how well one's life as a whole has gone.  相似文献

Lessons from safety-critical sociotechnical systems, such as aviation and acute medical care, demonstrate the importance of the human factor and highlight the crucial role of efficient communication between human agents. Although a large proportion of fatal incidents in aviation have been linked to failures in communication, cognitive engineering provides the theoretical framework to mitigate risks and increase performance in sociotechnical systems not only in the civil sector, but also in the military domain. Conducting cyber operations in multidomain battles presents new challenges for military training and education as the increased importance of psychological factors such as metacognitive skills and perspective-taking both in lower and higher ranking staff, becomes more apparent. The Hybrid Space framework (Jøsok et al., 2016) provides a blueprint for describing the cognitive and behavioral constraints for maneuvering between socio-technical and cyber-physical systems whilst cooperating, coordinating or competing with accompanying cognitive styles in the chain of command. We apply the Hybrid Space framework to communicative challenges in the military cyber domain and suggest a three-phase Orienting, Locating, Bridging model for safe and efficient communication between partners. Based on the educational principles of the Norwegian Defence Cyber Academy, we discuss the required skill-sets and knowledge in which cyber officer cadets are trained and taught early in their education, and how these refer to the theoretical framework of the Hybrid Space and the key principles of communication as defined in cognitive engineering.  相似文献

Recent mechanistic models of cognitive control define the normative level of control deployment as a function of the effort cost of exerting control balanced against the reward that can be attained by exerting control. Despite these models explaining empirical findings in adults, prior literature has suggested that adolescents may not adaptively integrate value into estimates of how much cognitive control they should deploy. Moreover, much work in adolescent neurodevelopment casts social valuation processes as competing with, and in many cases overwhelming, cognitive control in adolescence. Here, we test whether social incentives can adaptively increase cognitive control. Adolescents (Mage = 14.64, 44 male, N = 87) completed an incentivized cognitive control task in which they could exert cognitive control to receive rewards on behalf of real peers who were rated by all peers in their school grade as being of either high- or low-status. Using Bayesian modeling, we find robust evidence that adolescents exert more cognitive control for high- relative to low-status peers. Moreover, we demonstrate that social incentives, irrespective of their high- or low-status, boost adolescent cognitive control above baseline control where no incentives are offered. Findings support the hypothesis that the cognitive control system in early adolescence is flexibly modulated by social value.  相似文献

Given the increasing complexity of the tasks and skills needed in modern society, developing effective training strategies is of tremendous practical importance. Furthermore, training that improves performance of both trained and untrained tasks would be highly efficient. In the present study, we examined how directed training contributes to skill acquisition, and more importantly, to engendering transfer of training to untrained tasks. Participants learned a complex video game for 30 h (Space Fortress, Donchin, Fabiani, & Sanders, 1989) using one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET) in which participants simply practiced the game to obtain the highest overall score. We compared game performance, retention of training gains, and transfer of training to untrained tasks as a function of the training regimen. Compared to FET, HVT learners reached higher levels of mastery on the game and HVT was particularly beneficial for initially poor performing participants. This benefit persisted seven months after training. However, contrary to expectation, both HVT and FET were unsuccessful in producing transfer to untrained tasks compared to a group that received limited game experience, suggesting that directed training and practice can produce task-specific improvements, but improvements do not necessarily transfer from trained to untrained tasks.  相似文献
