Many studies have identified the prefrontal cortex as the brain area that is critical for spatial memory, both in humans and in other primates. Other studies, however, have failed to establish this relation. Therefore, the aim of this paper was to review the literature regarding the role of the human prefrontal lobe in spatial memory. This was done by examining the evidence obtained from neuropsychological patients and from studies using brain-imaging techniques (PET and fMRI). Evidence supporting the notion that the prefrontal cortex is extensively involved in spatial working memory was found. The majority of these studies, however, suggests that frontal-lobe involvement is not related to the type of material that is being processed (e.g., spatial vs. nonspatial), but to process-specific functions, such as encoding and retrieval. Theoretically, these functions could be linked to the central executive within Baddeley's working-memory model, or to recent theories that emphasize the various processes that play a role in working memory. Also, methodological issues were discussed. Further research is needed to enhance our understanding of the precise interaction of domain-specific and general processes.  相似文献

Increasingly, contemporary medical ethicists have become aware of the need to explicate a foundation for their various models of applied ethics. Many of these theories are inspired by the apparent incompatibility of patient autonomy and provider beneficence. The principle of patient autonomy derives its current primacy to a large extent from its legal origins. However, this principle seems at odds with the clinical reality. In the bioethical literature, the notion of authenticity has been proposed as an alternative foundational principle to autonomy. This article examines this proposal in reference to various existentialist philosophers (Heidegger, Sartre, Camus and Marcel). It is concluded that the principle of autonomy fails to do what it is commonly supposed to do: provide a criterion of distinction that can be invoked to settle moral controversies between patients and providers. The existentialist concept of authenticity is more promising in at least one crucial respect: It acknowledges that the essence of human life disappears from sight if life's temporal character is reduced to a series of present decisions and actions. This also implies that the very quest for a criterion that allows physicians to distinguish between sudden, unexpected decisions of their patients to be or not to be respected, without recourse to the patient's past or future, is erroneous.  相似文献

The framework of Positive Youth Development (PYD) arose from a strength‐based conception of the transition to adulthood. Although previous literature has provided evidence for some PYD correlates, little is known about gender differences in PYD and its outcomes in thriving and social engagement, which could improve interventions” effectiveness. Thus, this study aimed to examine gender differences in PYD dimensions (i.e., competence, confidence, connection, caring, and character), individual thriving (i.e., psychological adjustment, academic adjustment, and healthy lifestyles) and social engagement, and to examine the associations between them. Data from the ‘PYD in a Cross‐National Perspective Project” in Spain were collected by administering a paper‐based self‐report to students from high school and university. Results showed greater scores in connection, caring, and character in women, as well as greater social engagement and academic adjustment. Men presented higher competence and confidence, more frequent physical activity and better psychological adjustment. In addition, more PYD was related to greater social engagement, better psychological and academic adjustment, and healthier lifestyles. Some practical implications for program design may be derived, which underscore the need to promote the five PYD dimensions equally in female and male youths in order to improve their individual thriving and social engagement.  相似文献

This article proposes a new theoretical framework for the reviewed state‐of‐the‐art research on collective narcissism—the belief that the ingroup’s exceptionality is not sufficiently appreciated by others. Collective narcissism is motivated by the investment of an undermined sense of self‐esteem into the belief in the ingroup’s entitlement to privilege. Collective narcissism lies in the heart of populist rhetoric. The belief in ingroup’s exceptionality compensates the undermined sense of self‐worth, leaving collective narcissists hypervigilant to signs of threat to the ingroup’s position. People endorsing the collective narcissistic belief are prone to biased perceptions of intergroup situations and to conspiratorial thinking. They retaliate to imagined provocations against the ingroup but sometimes overlook real threats. They are prejudiced and hostile. Deficits in emotional regulation, hostile attribution bias, and vindictiveness lie behind the robust link between collective narcissism and intergroup hostility. Interventions that support the regulation of negative emotions, such as experiencing self‐transcendent emotions, decrease the link between collective narcissism and intergroup hostility and offer further insights into the nature of collective narcissism.  相似文献

Using evidence‐based guidelines to interview children is an important means to obtain complete and accurate accounts. In the current study, we examined the quality of child investigative interviewing in the Netherlands. To examine this, we compared the Dutch Scenario Model with the National Institute of Child Health and Human Development Protocol and interviews from countries that did not follow a specific protocol. Our principal result was that Dutch child interviewers rarely asked recommended open prompts that are known to elicit detailed and accurate testimonies from children. Furthermore, we found that the scenario model contained the highest number of directive questions compared with interviews from other countries. Our findings show that the Dutch Scenario Model is not well aligned with current research‐based recommendations for interviewing children.  相似文献
