Many of the key policy issues now facing the nation are behavioral in nature. Among these are educating and training citizens who can earn and keep jobs in a changing global economy; changing the behaviors that now cause half of all deaths in the country (e.g., smoking, poor diet and exercise patterns, and alcohol and drug abuse); reducing crime and violence; providing for an aging population; harnessing new information technologies to improve our quality of life; and reducing environmental pollution. These problems contrast with the defining policy challenges of the Cold War era, which demanded expertise primarily from the physical sciences.
Fortunately, the pressing need to solve behavioral problems arises at a time when rapid advances in behavioral, cognitive, and sensory sciences are improving our ability to address the problems. The time is ripe to strengthen the links between scientists and the policy community to harness new scientific advances to pressing public needs. To help forge these links, the National Research Council's (NRC) Commission on Behavioral and Social Sciences and Education (CBASSE) established a Board on Behavioral, Cognitive, and Sensory Sciences. This paper explains the need for this effort, and its potential. The report discusses the new promise of behavioral, cognitive, and sensory sciences, outlines the CBASSE record in these fields and its broadening focus on science-related policy questions; notes a range of emerging issues in which policy can benefit from expertise in these areas; and describes the functions of the new board.  相似文献

Since the WHO declared the COVID-19 pandemic on March 11, 2020, the novel coronavirus, SARS-CoV-2, has profoundly impacted public health and the economy worldwide. But there are not the only ones to be hit. The COVID-19 pandemic has also substantially altered mental health, with anxiety symptoms being one of the most frequently reported problems. Especially, the number of people reporting anxiety symptoms increased significantly during the first lockdown-phase compared to similar data collected before the pandemic. Yet, most of these studies relied on a unitary approach to anxiety, wherein its different constitutive features (i.e., symptoms) were tallied into one sum-score, thus ignoring any possibility of interactions between them. Therefore, in this study, we seek to map the associations between the core features of anxiety during the first weeks of the first Belgian COVID-19 lockdown-phase (n = 2,829). To do so, we implemented, in a preregistered fashion, two distinct computational network approaches: a Gaussian graphical model and a Bayesian network modelling approach to estimate a directed acyclic graph. Despite their varying assumptions, constraints, and computational methods to determine nodes (i.e., the variables) and edges (i.e., the relations between them), both approaches pointed to excessive worrying as a node playing an especially influential role in the network system of the anxiety features. Altogether, our findings offer novel data-driven clues for the ongoing field’s larger quest to examine, and eventually alleviate, the mental health consequences of the COVID-19 pandemic.  相似文献

The mental health of college students is increasingly viewed as an important public health priority. However, there has been little attention paid specifically to college students’ perspectives on factors that contribute to mental health challenges or on potential initiatives that could address them. Even less research has focused on students in low- and middle-income countries. In an effort to better understand how to improve mental health and wellness on college campuses, we administered an open-ended survey to 141 Indian college students (Mage = 19.47, 65% female). We asked the students to identify: (a) issues that contribute to mental health problems among college students, (b) potential initiatives or strategies that could be used to improve mental health and wellness, and (c) topics that students would like to learn about in a course about mental health and wellness. Applying thematic analysis, we identified academic stressors (e.g., pressure to succeed, competitiveness) and social stressors (e.g., lack of community, party culture and substance abuse) that students reported as contributors to mental health problems. Students also described mental health promotion strategies that could be implemented by faculty members (e.g., providing academic accommodations for students with mental health concerns), the student body (e.g., establishing peer counseling groups), and individual students (e.g., checking in with others). Finally, they identified topics that they would like to learn about in mental health and wellness courses (e.g., how to identify mental health concerns, how to support friends). By raising several potential targets for mental health and wellness interventions for Indian college students, our study illustrates how open-ended surveys can be a useful and feasible way to solicit input from stakeholders in low- and middle-income countries. Future research will be needed to assess the effectiveness and feasibility of mental health promotion strategies, including those proposed by students.  相似文献

This study explored the psychosocial mechanisms of change associated with differences in levels and linear change of adolescents' global life satisfaction across a 2-year time period. Based on a theoretical model proposed by Evans (1994), this study tested the relations between selected personality (i.e., extraversion and neuroticism) and environmental (stressful life events) variables and global life satisfaction when mediated by internalizing and externalizing problems. The results suggested support for internalizing problems as a mediator of the relationship of personality and environmental variables with life satisfaction. Pathways mediated by internalizing problems significantly predicted levels and linear change of life satisfaction across a 2-year time span. Furthermore, pathways mediated by externalizing problems significantly predicted the level but not the linear change of life satisfaction. Thus, behavior problems and their antecedents appear to relate significantly to adolescents' perceptions of their quality of life. Implications for adolescent mental health promotion were discussed.  相似文献

The relation between developed and developing countries is characterized by inequalities that sometimes hinder actions against worldwide problems. The current research presents an intergroup approach, based on the ingroup projection model, towards an analysis of psychological processes that perpetuate global inequality on a social group level. Precisely, we argue that people from developed countries perceive their group as more prototypical for the world population than they perceive people from developing countries. These perceptions of ingroup prototypicality should in turn relate to legitimacy beliefs and predict unfavorable behavioral intentions towards developing countries. We present two studies that corroborate our hypotheses: In Study 1, participants from a developed country perceived their ingroup as more prototypical for the superordinate group (i.e., world population) than the outgroup (i.e., developing countries), which in turn was related to beliefs that global inequality is legitimate. This finding was replicated in Study 2, and the predicted effect of ingroup prototypicality on behavioral intentions was mediated by legitimacy beliefs. These findings demonstrate that intergroup processes can contribute to perpetuating global inequality.  相似文献

Individuals have many life experiences (e.g., work and vacations) that consist of a series of interconnected episodes (i.e., temporal sequences). Assessments of such experiences are integral to daily life in that they facilitate future planning and behaviors for individuals. Therefore, these experiences often culminate in evaluations of their global affect. Past work has shown that retrospective, affective evaluations of these sequences generally exhibit an “end effect,” whereby a sequence's end intensity—but not its start intensity—is disproportionately weighted. Yet, researchers have largely investigated experiences that occur alone. In contrast, many real‐world experiences vary in their extent of social connection to others (e.g., working in an office with others versus alone in a cubicle). The present work fills this gap by showing the moderating role of social connection on how episodes are weighted in global affective ratings. Five studies involving two autobiographical experiences spanning several days each (workweek and spring break) and two brief simulated experiences show that high social connection leads to greater (lesser) weighting of the first (last) episode. To our knowledge, we are the first to demonstrate that these effects persist across different forms of social connection (i.e., interpersonal interaction versus semantic priming tasks) and are supported regardless of whether social connection occurs at encoding or retrieval of an experience.

The general and deep dissatisfaction with the present-day status of health care is of such intensity that one speaks of a health care crisis. What is most disturbing to the physicians is that society directs its accusation mainly at the health care professional for being responsible for this crisis. If we want to abolish the crisis we must try to get a renewed look at its source, i.e., to answer the questions “where did health care go wrong primarily?” and “with whom lies the ultimate responsibility for health care?”. In the following discourse these questions are discussed. Based on the assumption that every human being is a free rational agent the ultimate health care responsibility is assigned to the citizen. Of course, whether such an approach will in fact solve the problems inherent in present-day health systems cannot be predicted.  相似文献

Outlining the characteristics of “wicked” and “super‐wicked” problems, climate change is considered as a global super‐wicked problem that is primarily about the future. Being global‐ and future‐oriented makes climate change something we have to learn to live with but cannot expect to solve. Because the Institute on Religion in an Age of Science (IRAS) is a multidisciplinary society that yokes the natural and social sciences with values, it is in a position to explore strategies for living with climate change—exemplified by the articles in this section. Finally, asking “who/what is in charge,” it is suggested that in a dynamically interrelated and evolving world no one is. It is important to distinguish between good that is already created and the creative interactions that give rise to new good. In order to live with climate change, our primary orientation should be to live with the creativity that has created and continues to create our life on Planet Earth—since we are not able to know what the future holds.  相似文献

Environmental problems have been perceived as more worrying when they take place at greater distances. This phenomenon has been called “environmental hyperopia” ( 9 Uzzell, 2000; 7 Uzzell, Rice, Ballantyne, & Podlucká, 1994). Some studies have demonstrated that local environmental problems are perceived as being less important than the problems generated in other places, such as global warming or Amazon deforestation, unless the problem leads to an immediate risk. This article is part of a broader research programme, which tries to analyse the most relevant variables in the formation of pro‐environmental attitudes. More precisely, our intention is to explore the difference between attitudes about local and global environments. We present a study of the assessment of several environmental problems, in which 12 scales measured the importance given to these problems by a sample of students. The results were analysed with multidimensional methods, allowing us to establish temporal and space dimensions in the perception of environmental problems. The conclusions allowed us not only to explore the social representation of environmental problems, but also to establish priorities and recommendations for future environmental education programmes.  相似文献

Age discrimination at work is a widespread destructive phenomenon that often takes subtle forms. Based on negative stereotypes about older employees, we argue that older employees often experience that they are perceived as less ideal followers than younger employees. We propose that older and younger employees do not differ in what they assume their supervisors expect of an ideal follower (implicit followership theories, IFTs). Thus, we hypothesize that older employees perceive that they compare less favorably to their supervisors' IFTs than younger employees (i.e., worse IFT-fit). This should entail lower quality of the relationship between leader and follower (leader-member-exchange, LMX), which, in turn, should have detrimental effects on employees' health (i.e., burnout) and job attitudes (i.e., job satisfaction, turnover intentions, and identification). We tested our model in a field study with 379 employees. Results differed for ideal and counter-ideal follower attributes. Concerning counter-ideal follower attributes (e.g., being incompetent), age had the proposed negative effect on psychological health and job attitudes that mediated through IFT-fit and LMX. Concerning ideal follower attributes (e.g., thinking ahead), older employees expected their supervisors not only to think less of them than of their younger colleagues, but also expected them to have less demanding IFTs—contrary to our expectations. Employee age was negatively related to psychological health and job attitudes, mediated through lower perceived IFTs, worse perceived appraisal of the actual employee and their joint effects on LMX.  相似文献

Spatial memories are often organized around reference frames, and environmental shape provides a salient cue to reference frame selection. To date, however, the environmental cues responsible for influencing reference frame selection remain relatively unknown. To connect research on reference frame selection with that on orientation via environmental shape, we explored the extent to which geometric cues were incidentally encoded and represented in memory by evaluating their influence on reference frame selection. Using a virtual environment equipped with a head-mounted-display, we presented participants with to-be-remembered object arrays. We manipulated whether the experienced viewpoint was aligned or misaligned with global (i.e., the principal axis of space) or local (i.e., wall orientations) geometric cues. During subsequent judgments of relative direction (i.e., participants imagined standing at one object, facing a second object, and pointed toward a third object), we show that performance was best when imagining perspectives aligned with these geometric cues; moreover, global geometric cues were sufficient for reference frame selection, global and local geometric cues were capable of exerting differential influence on reference frame selection, and performance from experienced-imagined perspectives was equivalent to novel-imagined perspectives aligned with geometric cues. These results explicitly connect theory regarding spatial reference frame selection and spatial orientation via environmental shape and indicate that spatial memories are organized around fundamental geometric properties of space.  相似文献

本研究采用纵向设计,以北京市426名四、五年级流动儿童为被试,进行连续4次的追踪测查,考察流动儿童同伴侵害的特点及其与内化问题的动态相互作用关系。结果发现:(1)打工子弟学校流动儿童的同伴侵害与内化问题水平比公立学校流动儿童高;流动儿童的流动性越大,同伴侵害和内化问题越多。(2)控制了性别、年级、家庭社会经济地位(SES)和流动性后,从T1到T2,同伴侵害与孤独感为相互作用关系,且同伴侵害可以显著预测抑郁,但对社交焦虑的预测作用不显著,而从T2到T4,同伴侵害和3种内化问题的相互作用模式完全一致,即T2时的社交焦虑、抑郁和孤独感显著预测T3的同伴侵害,进而显著预测T4的社交焦虑、抑郁和孤独感。(3)抑郁、孤独感与同伴侵害的循环作用在两类流动儿童中具有较强的稳定性,而在社交焦虑和同伴侵害的模型中,打工子弟学校流动儿童的同伴侵害对社交焦虑的作用比公立学校流动儿童更大。可见,同伴侵害和内化问题呈循环作用关系,未来预防/干预研究可以聚焦于减少流动儿童的同伴侵害或内化问题的角度打破二者的恶性循环,帮助他们建立良好的人际关系,构建良性循环,促进他们的积极发展。  相似文献

This study examined the associations between older adults' daily physical symptoms (e.g., chest pain or difficulty breathing) and 2-year changes in chronic health problems (e.g., cardiovascular disease or cancer) and in functional problems (e.g., difficulty dressing or moving around at home). We reasoned that these associations depend on a person's active control processes aimed at counteracting physical health problems (i.e., health-engagement control strategies, or HECS). In particular, we hypothesized that high levels of HECS buffer the adverse effect of daily physical symptoms on increases in chronic and functional health problems. We found that daily physical symptoms were associated with declines in chronic and functional health among older adults who were not engaged in addressing their health problems, but not among their counterparts who reported high levels of HECS. These findings suggest that active control strategies play an important role in the maintenance of older adults' physical health.  相似文献

In the context of worldwide economic and environmental crisis it is increasingly important that nanotechnology, genomics, media engineering and other fields of ‘technoscience’ with immense societal relevance are taught in ways that promote social responsibility and that educational activities are organized so that science and engineering students will be able to integrate the ‘contextual knowledge’ they learn into their professional, technical–scientific identities and forms of competence. Since the 1970s, teaching programmes in science, technology and society for science and engineering have faded away at many universities and have been replaced by courses in economic and commercial aspects, or entrepreneurship and/or ethical and philosophical issues. By recounting our recent efforts in contextualizing nanotechnology education at Aalborg University in Denmark, we consider a socio-cultural approach to contextual learning, one that is meant to contribute to a greater sense of social responsibility on the part of scientists and engineers. It is our contention that the social, political and environmental challenges facing science and engineering in the world today require the fostering of what we have come to call a ‘hybrid imagination’, mixing scientific–technical skills with a sense of social responsibility or global citizenship, if science and engineering are to help solve social problems rather than create new ones. Three exemplary cases of student project work are discussed: one on raspberry solar cells, which connected nanotechnology to the global warming debate, and two in which surveys on the public understanding of nanotechnology were combined with a scientific–technical project.  相似文献

Models for operationalizing the sex-role constructs androgyny and sex-typing are reviewed, and problems discussed. A new (principal components) model representing an exact solution is derived and shown to solve existing problems. In this model, androgyny is a function of the sum of standardized instrumentality and expressiveness scores, and sex-typing a function of the difference between these scores. Formal operationalization of these constructs reveals that they may have theoretical utility in only very contrived contingencies, and an alternative profile matching model is proposed. This latter theory, which is not yet fully specified, hypothesizes that an individual's performance is maximized when the critical operating characteristics of a contingency (i.e., instrumental and expressive behaviors required for maximal performance to result) exactly match the individual's specific instrumental and expressive predispositions, and that performance decreases as the discrepancy between the instrumental/expressive profiles of the individual and the contingency increases.  相似文献

Multiple spatial cues are utilized to orient with respect to the environment, but it remains unclear why feature (i.e., objects in the environment) and geometric (i.e., shape of the environment) cues are differentially influenced by enclosure size, and the extent to which local (i.e., wall lengths and corner angles) and global (i.e., principal axis of space) geometric cues are influenced by enclosure size. In the present study, we investigated the extent to which environmental size influenced the use of corner angle (i.e., a local geometric cue) and the principal axis of space (i.e., a global geometric cue) for reorientation. We developed an orientation task that allowed the manipulation of enclosure size during training and the isolation of the use of the principal axis of space during testing. Participants were trained to respond to a location in either a small or a large trapezoid-shaped enclosure uniquely specified by both local (i.e., wall lengths and corner angles) and global (i.e., principal axis of space) geometric cues. During testing, we presented both groups with a small and large rectangle (to assess the use of principal axis of space) and a small and large parallelogram (to asses relative use of corner angles and the principal axis of space when in conflict). Enclosure size influenced the relative use of corner angles but not of the principal axis of space. Results suggest that corner angles function like features and that changes in the use of feature cues are the source of the relative reliance on feature and geometric cues during changes of enclosure size.  相似文献

How do kindergarteners solve different single-digit addition problem formats? We administered problems that differed solely on the basis of two dimensions: response type (approximate or exact), and stimulus type (nonsymbolic, i.e., dots, or symbolic, i.e., Arabic numbers). We examined how performance differs across these dimensions, and which cognitive mechanism (mental model, transcoding, or phonological storage) underlies performance in each problem format with respect to working memory (WM) resources and mental number line representations. As expected, nonsymbolic problem formats were easier than symbolic ones. The visuospatial sketchpad was the primary predictor of nonsymbolic addition. Symbolic problem formats were harder because they either required the storage and manipulation of quantitative symbols phonologically or taxed more WM resources than their nonsymbolic counterparts. In symbolic addition, WM and mental number line results showed that when an approximate response was needed, children transcoded the information to the nonsymbolic code. When an exact response was needed, however, they phonologically stored numerical information in the symbolic code. Lastly, we found that more accurate symbolic mental number line representations were related to better performance in exact addition problem formats, not the approximate ones. This study extends our understanding of the cognitive processes underlying children's simple addition skills.  相似文献

Self‐image goals focus on constructing, maintaining, and defending desired public and private images of the self, whereas compassionate goals focus on being supportive and not harming others. We suggest that these goals shape construals of others in relation to the self, which in turn, shape affective experiences. We review research showing that when people have self‐image goals, they construe others as competitors, which leads to feeling uneasy with others (i.e., conflicted, confused, and fearful), and that when they have compassionate goals, they construe others as collaborators and have more constructive approaches to interpersonal problems, which leads to feeling at ease with others (i.e., peaceful, clear, and loving) and less upset with them. Thus, interpersonal goals shape construals of others, which in turn shape intrapsychic experiences of the world and of the self.  相似文献

COVID-19 underscores the importance of understanding variation in adherence to rules concerning health behaviors. Children with conduct problems have difficulty with rule adherence, and linking early conduct problems with later adherence to COVID-19 guidelines can provide new insight into public health. The current study employed a sample (N = 744) designed to examine the longitudinal consequences of childhood conduct problems (Mean age at study entry = 8.39). The first objective was to link early conduct problems with later adherence to both general and specific COVID-19 guidelines during emerging adulthood (M age = 19.07). The second objective was to prospectively examine how interactional (i.e., callous unemotional traits, impulsivity) and cumulative (i.e., educational attainment, work status, substance use) continuity factors mediated this association. The third objective was to examine differences in sex assigned at birth in these models. Direct associations were observed between childhood conduct problems and lower general, but not specific COVID-19 guideline adherence. Conduct problems were indirectly associated with both general and specific adherence via higher levels of callous unemotional traits, and with specific adherence via higher problematic substance use. No differences in the models were observed across sex assigned at birth. Findings provide insight into both how developmental psychopathology constructs are useful for understanding COVID-19 guideline adherence, and the ways in which conduct problems may shape health outcomes.
