Individual differences in young children's frustration responses set the stage for myriad developmental outcomes and represent an area of intense empirical interest. Emotion regulation is hypothesized to comprise the interplay of complex behaviors, such as facial expressions, and activation of concurrent underlying neural systems. At present, however, the literature has mostly examined children's observed emotion regulation behaviors and assumed underlying brain activation through separate investigations, resulting in theoretical gaps in our understanding of how children regulate emotion in vivo. Our goal was to elucidate links between young children's emotion regulation‐related neural activation, facial muscular movements, and parent‐rated temperamental emotion regulation. Sixty‐five children (age 3–7) completed a frustration‐inducing computer task while lateral prefrontal cortex (LPFC) activation and concurrent facial expressions were recorded. Negative facial expressions with eye constriction were inversely associated with both parent‐rated temperamental emotion regulation and concurrent LPFC activation. Moreover, we found evidence that positive expressions with eye constriction during frustration may be associated with stronger LPFC activation. Results suggest a correspondence between facial expressions and LPFC activation that may explicate how children regulate emotion in real time.  相似文献

Although much has been written on the dead-donor rule (DDR) in the last twenty-five years, scant attention has been paid to how it should be formulated, what its rationale is, and why it was accepted. The DDR can be formulated in terms of either a Don’t Kill rule or a Death Requirement, the former being historically rooted in absolutist ethics and the latter in a prudential policy aimed at securing trust in the transplant enterprise. I contend that the moral core of the rule is the Don’t Kill rule, not the Death Requirement. This, I show, is how the DDR was understood by the transplanters of the 1960s, who sought to conform their practices to their ethics—unlike today’s critics of the DDR, who rethink their ethics in a question-begging fashion to accommodate their practices. A better discussion of the ethics of killing is needed to move the debate forward.  相似文献

An intrinsic part of seeing objects is seeing how similar or different they are relative to one another. This experience requires that objects be mentally represented in a common format over which such comparisons can be carried out. What is that representational format? Objects could be compared in terms of their superficial features (e.g., degree of pixel-by-pixel overlap), but a more intriguing possibility is that they are compared on the basis of a deeper structure. One especially promising candidate that has enjoyed success in the computer vision literature is the shape skeleton—a geometric transformation that represents objects according to their inferred underlying organization. Despite several hints that shape skeletons are computed in human vision, it remains unclear how much they actually matter for subsequent performance. Here, we explore the possibility that shape skeletons help mediate the ability to extract visual similarity. Observers completed a same/different task in which two shapes could vary either in their skeletal structure (without changing superficial features such as size, orientation, and internal angular separation) or in large surface-level ways (without changing overall skeletal organization). Discrimination was better for skeletally dissimilar shapes: observers had difficulty appreciating even surprisingly large differences when those differences did not reorganize the underlying skeletons. This pattern also generalized beyond line drawings to 3-D volumes whose skeletons were less readily inferable from the shapes’ visible contours. These results show how shape skeletons may influence the perception of similarity—and more generally, how they have important consequences for downstream visual processing.

Despite the awe and wonder that discoveries related to astrobiology inspire, the sheer volume and diversity of new discoveries related to space science can become overwhelming without meaningful frames of reference by which to organize our understanding of these phenomena. I suggest that a critical feature of the future of “astrotheology” relates to how it serves as an organizing correlate to astrobiology and space research. Considering that the prefix astro‐ has an amplicative and abductive effect on the fields of study to which it is applied, I contend that astrotheology implies a creative and constructive shift in how we conceptualize meaningful human being for theology that parallels how astrobiology effects a creative and constructive shift in how we conceptualize living systems.  相似文献

Suicide is the second leading cause of death for those ages 13–25 in the United States. Coping is a mediator between stressful life events and adverse outcomes, and coping skills have been incorporated into interventions (e.g., cognitive-behavioral therapy, dialectical behavior therapy, safety-planning interventions) for suicidal populations. However, longitudinal research has not directly examined the prospective associations between multiple coping styles and suicide-related outcomes in high-risk samples. This study identified cross-sectional and 4-month longitudinal associations of coping styles with suicide risk factors (i.e., depression, suicidal ideation, suicidal behavior) in a sample of 286 adolescent and young adult psychiatric emergency patients. Positive reframing was the coping style most consistently associated with positive outcomes, whereas self-blame and disengagement were consistently associated with negative outcomes. Active coping protected against suicidal behavior for males, but not for females. This was the first study to examine longitudinal relationships between coping and suicide-related outcomes in a high-risk clinical sample. Findings suggest that clinical interventions with suicidal adolescents and young adults may benefit from a specific focus on increasing positive reframing and reducing self-blame.  相似文献

Global matching models have provided an important theoretical framework for recognition memory. Key predictions of this class of models are that (1) increasing the number of occurrences in a study list of some items affects the performance on other items (list-strength effect) and that (2) adding new items results in a deterioration of performance on the other items (list-length effect). Experimental confirmation of these predictions has been difficult, and the results have been inconsistent. A review of the existing literature, however, suggests that robust length and strength effects do occur when sufficiently similar hard-to-label items are used. In an effort to investigate this further, we had participants study lists containing one or more members of visual scene categories (bathrooms, beaches, etc.). Experiments 1 and 2 replicated and extended previous findings showing that the study of additional category members decreased accuracy, providing confirmation of the category-length effect. Experiment 3 showed that repeating some category members decreased the accuracy of nonrepeated members, providing evidence for a category-strength effect. Experiment 4 eliminated a potential challenge to these results. Taken together, these findings provide robust support for global matching models of recognition memory. The overall list lengths, the category sizes, and the number of repetitions used demonstrated that scene categories are well-suited to testing the fundamental assumptions of global matching models. These include (A) interference from memories for similar items and contexts, (B) nondestructive interference, and (C) that conjunctive information is made available through a matching operation.  相似文献

The efficacy and efficiency of telehealth and in‐person training were compared while teaching seven undergraduate students to implement components of discrete trial training. A multiple‐baseline design across skills with elements of multiple probe and delayed multiple baseline combined with an alternating‐treatments design was used to evaluate the effects of behavioral skills training (BST) on (a) implementing a multiple stimulus without replacement preference assessment, (b) setting up an instructional context, (c) delivering antecedent prompts, and (d) delivering consequences for accurate and inaccurate responding. Two skills were trained via telehealth and two skills were trained in‐person using BST procedures with a mock student. All participants provided high acceptability ratings for both training procedures. Results also showed that telehealth training was as efficacious and efficient as in‐person training for all skills across all participants. Five of six participants showed high levels of maintenance of the newly acquired skills; these five also exhibited the skills during a novel instructional task.  相似文献

This study investigated the influence of student-teacher relationships and attitudes toward bullying on middle school students' bullying behaviors. Gender and grade differences were also examined. Data were collected from 435 middle school students. Results indicated that students' attitudes toward bullying mediated the relationship between student-teacher relationships and physical and verbal/relational bullying. There was a significant group difference on student-teacher relationships and attitudes toward bullying between bully, bully-victim, victim, and bystander groups and students not involved in bullying. In addition, sixth graders reported significantly more positive student-teacher relationships than seventh and eighth graders. Implications for the role of both cognitive and behavioral bullying intervention and prevention efforts are discussed.  相似文献

Anhedonia—the reduced capacity to experience pleasure—is a trait implicated in mental and physical health. Yet, psychometric data on anhedonia measures in adolescents are absent. We conducted an in-depth psychometric analysis of the Snaith–Hamilton Pleasure Scale (SHAPS; Snaith et al., 1995 Snaith, R. P., Hamilton, M., Morley, S., Humayan, A., Hargreaves, D., & Trigwell, P. (1995). A scale for the assessment of hedonic tone: The Snaith–Hamilton Pleasure Scale. British Journal of Psychiatry, 167, 99103. doi:10.1192/bjp.167.1.99[Crossref], [PubMed], [Web of Science ®] [Google Scholar])—a self-report measure of anticipated pleasure response to 14 pleasant experiences—in adolescents. Adolescents (N = 585, M age = 14.5) completed the SHAPS and other paper-and-pencil surveys. Item response theory models were used to evaluate the psychometric performance of each SHAPS item. Correlations of the SHAPS with other personality and psychopathology measures were calculated to evaluate construct validity. Results showed that (a) certain items (e.g., reported pleasure from basic experiences like “seeing smiling faces” or “smelling flowers”) provided more information about latent anhedonia than others; and (b) SHAPS scales exhibited construct-consistent convergent and discriminant validity (i.e., stronger correlations with low positive affect constructs, weaker correlations with negative affect). Reporting diminished pleasure from basic pleasant experiences accurately indicates adolescent anhedonia, which is important for future scale development and understanding the phenomenology of anhedonia in teens. These data support using the SHAPS for assessing anhedonia in epidemiological research and school-based universal prevention programming in general adolescent populations.  相似文献
