目的:探讨心理弹性在社会支持与流动儿童社会退缩之间的中介作用。方法:采用社会支持评定量表、青少年心理弹性量表和班级戏剧量表对258名流动儿童进行调查。结果表明:(1)活跃退缩与社会支持、心理弹性呈显著负相关; 安静退缩与社会支持相关不显著,与心理弹性呈显著负相关; 社会支持与心理弹性呈显著正相关;(2)社会支持、心理弹性显著负向预测流动儿童的活跃退缩;(3)心理弹性在社会支持与流动儿童活跃退缩之间具有完全中介作用。  相似文献

目的:探讨适应性自恋与病理性自恋对个体心理健康的不同影响。方法:750名大学生完成了一套由自恋人格问卷(NPI)、病理性自恋量表(PNI)和症状自评量表(SCL-90)组成的测验。利用结构方程模型对变量间的关系进行分析。结果表明:病理性自恋的二阶因子自恋易损性对个体心理健康具有显著的负向预测作用,自恋易损性水平越高,个体心理健康水平越低。自恋夸大性和适应性自恋(自恋人格问卷,NPI)对心理健康的正向预测作用达到边缘显著,自恋夸大性和适应性自恋得分越高,心理健康水平越高。结论:病理性自恋的二阶因子自恋易损性对心理健康具有明显的破坏作用,而自恋夸大性和正常/适应性自恋可能对心理健康存在微弱的保护作用。  相似文献

This study focuses on the reliability and validation of the Chinese version of the Moral Attentiveness Scale. Factor analysis confirmed that the scale includes two factors: perceptual moral attentiveness and reflective moral attentiveness. Moral attentiveness is negatively correlated with normlessness and positively associated with internalization and symbolization, moral identity, and other academic dishonesty behaviors. Reflective moral attentiveness moderated the relationship between formalism and unethical decision making. All results showed that the Chinese version of the Moral Attentiveness Scale has satisfactory psychometric properties and is a valid and reliable measurement of moral attentiveness in the Chinese population.  相似文献

Religious involvement has long been argued to have protective effects for negative behavioral health outcomes for vulnerable youth. This study builds on the existing resilience literature and need for more studies that examine protective factors associated with behavioral health. A sample of 638 low-income African American adolescents in Chicago to examine within group variations of the influence of religious involvement on delinquency, school engagement, substance use and sexual risk behaviors, and whether such relationships differ by gender, sexual orientation, and socioeconomic status. Logistic regression findings documented that greater religious involvement was protective with regards to lower rates of delinquency, drug use, risky sexual behaviors and higher rates of school engagement, and that gender, sexual orientation and socioeconomic status varied for several of these relationships. Overall findings are discussed with regards to future research.  相似文献

An attentional control setting (ACS), which is based on the task goal, induces involuntary attentional capture by a stimulus possessing a target-defining feature. It is unclear whether ACSs are maintained for multiple targets defined as conjunctions of a color and location. In the present study we examined the possibility of local ACSs for dual targets defined as combinations of color and location, using different paradigms: visual search in Experiment 1, and spatial cueing in Experiment 2. In Experiment 1, a distractor captured attention only when its features matched the ACSs. Likewise, in Experiment 2, a significant attentional capture effect was found only with a matching cue, whose color and location were in line with the conjunction of the target definition. Importantly, the identical pattern of attentional capture was also obtained for a neutral-color target, which was unlikely to be primed by any color of the cue. Thus, these findings imply that the attentional bias depending on the match between the cue and target did not result from cue–target repetition priming. The present study highlights that top-down attentional control can be set flexibly to accomplish a complex task goal efficiently.  相似文献

This paper demonstrates the usefulness and flexibility of the general structural equation modelling (SEM) approach to fitting direct covariance patterns or structures (as opposed to fitting implied covariance structures from functional relationships among variables). In particular, the MSTRUCT modelling language (or syntax) of the CALIS procedure (SAS/STAT version 9.22 or later: SAS Institute, 2010) is used to illustrate the SEM approach. The MSTRUCT modelling language supports a direct covariance pattern specification of each covariance element. It also supports the input of additional independent and dependent parameters. Model tests, fit statistics, estimates, and their standard errors are then produced under the general SEM framework. By using numerical and computational examples, the following tests of basic covariance patterns are illustrated: sphericity, compound symmetry, and multiple‐group covariance patterns. Specification and testing of two complex correlation structures, the circumplex pattern and the composite direct product models with or without composite errors and scales, are also illustrated by the MSTRUCT syntax. It is concluded that the SEM approach offers a general and flexible modelling of direct covariance and correlation patterns. In conjunction with the use of SAS macros, the MSTRUCT syntax provides an easy‐to‐use interface for specifying and fitting complex covariance and correlation structures, even when the number of variables or parameters becomes large.  相似文献

Recent experiments have been used to “edit” genomes of various plant, animal and other species, including humans, with unprecedented precision. Furthermore, editing the Cas9 endonuclease gene with a gene encoding the desired guide RNA into an organism, adjacent to an altered gene, could create a “gene drive” that could spread a trait through an entire population of organisms. These experiments represent advances along a spectrum of technological abilities that genetic engineers have been working on since the advent of recombinant DNA techniques. The scientific and bioethics communities have built substantial literatures about the ethical and policy implications of genetic engineering, especially in the age of bioterrorism. However, recent CRISPr/Cas experiments have triggered a rehashing of previous policy discussions, suggesting that the scientific community requires guidance on how to think about social responsibility. We propose a framework to enable analysis of social responsibility, using two examples of genetic engineering experiments.  相似文献

The influence of vehicular control on motion sickness has implications for theories of motion sickness etiology. We asked whether motion sickness susceptibility might also be related to the control of non-vehicular locomotion. Participants were exposed to a console video game that featured ambulatory locomotion of a virtual avatar. In a yoked control design, individuals either played the game (players) or watched another participant's recorded game play (viewers). Viewers were more likely than players to report motion sickness. During exposure to the video game players moved more than viewers, and the movement of players was more predictable or self-similar than the movement of viewers. Coupling of movement within player-viewer pairs was greater for pairs in which the viewer later reported motion sickness than for pairs in which both participants stated that they were not motion sick. The results reveal that motion sickness incidence can be influenced by the control of stimulus motion, in general, and is not limited to control of vehicular motion. We discuss implications of these findings for theories of motion sickness etiology.  相似文献
