We examined independent and interactive associations linking preadolescents' socially anxious feelings and peer victimization experiences with their social behaviors (rated by parents and teachers) and psychophysiological arousal during lab simulations of salient peer stress situations in preadolescence (peer evaluation and peer rebuff). Sixty-three preadolescents and one parent per preadolescent participated. Respiratory sinus arrhythmia (RSA), skin conductance level (SCL), and heart rate (HR) were assessed during peer stress situations. Preadolescents provided reports of social anxiety; preadolescents and parents reported on peer victimization; and parents and teachers rated prosocial and aggressive behaviors. Peer victimization moderated associations between social anxiety and both physiological arousal and social-behavior problems. As hypothesized, social anxiety was more strongly associated with lower RSA, higher HR, and higher aggressive behavior among preadolescents who experienced higher levels of peer victimization, compared to preadolescents who experienced lower levels of peer victimization. 相似文献

Vietnam’s continuing economic transformation has sharply increased the demand for highly-qualified business graduates. Vietnamese universities have responded to this increase in demand by improving the quality of their programs and raising their performance standards. The degree to which high-quality competitive programs increase students’ satisfaction with their educational experience is determined by their psychological hardiness in learning, their learning motivation, and their assessments of the functional value of business education. This study gathered survey data from a convenience sample of 1,024 business students in Vietnam, then validated measures of four constructs: Quality of College Life, psychological hardiness in learning, learning motivation, and perceived functional value of business education. The relationships among the constructs were estimated by Structural Equation Modeling. The results demonstrate that psychological hardiness in learning and learning motivation have statistically significant positive impacts on students’ perceived Quality of College Life. The impacts are significantly stronger for students with higher assessments of the functional value of a business education. These findings suggest that universities could enhance the Quality of College Life and academic performance by offering programs to cultivate students’ psychological hardiness in learning and their learning motivation, and by providing them with objective information about the functional value of business careers. 相似文献

Evaluative food categories are value‐laden assessments, which reflect the healthfulness and palatability of foods (e.g. healthy/unhealthy, yummy/yucky). In a series of three studies, this research examines how 3‐ to 4‐year‐old children (N = 147) form evaluative food categories based on input from external sources of information. The results indicate that children prefer to ask a mom and teacher over a cartoon and child for information about the evaluative status of foods. However, children are cautious to accept information about healthy foods from all of the external sources compared with unhealthy, yummy and yucky foods. The results also indicate that providing information about the positive taste of healthy foods helps to encourage children to select healthy foods to eat. Taken together, these results have potential implications for children's health and nutrition education. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Mediation analysis constitutes an important part of treatment study to identify the mechanisms by which an intervention achieves its effect. Structural equation model (SEM) is a popular framework for modeling such causal relationship. However, current methods impose various restrictions on the study designs and data distributions, limiting the utility of the information they provide in real study applications. In particular, in longitudinal studies missing data is commonly addressed under the assumption of missing at random (MAR), where current methods are unable to handle such missing data if parametric assumptions are violated. In this paper, we propose a new, robust approach to address the limitations of current SEM within the context of longitudinal mediation analysis by utilizing a class of functional response models (FRM). Being distribution-free, the FRM-based approach does not impose any parametric assumption on data distributions. In addition, by extending the inverse probability weighted (IPW) estimates to the current context, the FRM-based SEM provides valid inference for longitudinal mediation analysis under the two most popular missing data mechanisms; missing completely at random (MCAR) and missing at random (MAR). We illustrate the approach with both real and simulated data. 相似文献

This paper looks at the present situation of psychotherapy in France. In studying the historical background to the introduction of psychoanalysis in France since the 1920s, an assumption is made about the similar changes in paradigms brought about by the emergence of a new field, whether this be psychoanalysis or psychotherapy. 相似文献

Whispering gallery mode (WGM) sensors are created by coupling a dielectric microresonator with the evanescent field of an optical fiber. Since the sensor is created by two separate entities, most of the existing studies are limited to using them in fluid environments, such as air or water, for the ease of manipulation and placement in the optimum configuration. This work is focused on studying the possibility of using WGM sensors inside a solid material. The sensor is immersed in water, which is cooled to solid state and the sensor survival is monitored. In subsequent studies, three remelting cycles are carried out and temperature measurements are obtained through the sensor. The sensor output is calibrated with the temperature data obtained from a thermocouple. The results show that a linear relationship exists between temperature and WGM shift, which enables application of these sensors in temperature measurement. Considering that the sensitivity of WGM sensors is very high (10?6 N force and 10?5 K temperature), they can be used for high resolution studies on solidification in cryogenic environments. 相似文献

The ability to understand the similarity between two phenomena is fundamental for humans. Designated by the term analogy in psychology, this ability plays a role in the categorization of phenomena in the world and in the organisation of the linguistic system. The use of analogy in language often results in non-standard utterances, particularly in speakers with aphasia. These non-standard utterances are almost always studied in a nominal context and considered as errors. We propose a study of the verbal lexicon and present findings that measure, by an action-video naming task, the importance of verb-based non-standard utterances made by 17 speakers with aphasia (“la dame déshabille l’orange”/the lady undresses the orange, “elle casse la tomate”/she breaks the tomato). The first results we have obtained allow us to consider these type of utterances from a new perspective: we propose to eliminate the label of “error”, suggesting that they may be viewed as semantic approximations based upon a relationship of inter-domain synonymy and are ingrained in the heart of the lexical system. 相似文献

Measures of agreement are used in a wide range of behavioral, biomedical, psychosocial, and health-care related research to
assess reliability of diagnostic test, psychometric properties of instrument, fidelity of psychosocial intervention, and accuracy
of proxy outcome. The concordance correlation coefficient (CCC) is a popular measure of agreement for continuous outcomes.
In modern-day applications, data are often clustered, making inference difficult to perform using existing methods. In addition,
as longitudinal study designs become increasingly popular, missing data have become a serious issue, and the lack of methods
to systematically address this problem has hampered the progress of research in the aforementioned fields. In this paper,
we develop a novel approach to tackle the complexities involved in addressing missing data and other related issues for performing
CCC analysis within a longitudinal data setting. The approach is illustrated with both real and simulated data. 相似文献

What causes adolescents to be materialistic? Prior research shows parents and peers are an important influence. Researchers have viewed parents and peers as socialization agents that transmit consumption attitudes, goals, and motives to adolescents. We take a different approach, viewing parents and peers as important sources of emotional support and psychological well-being, which increase self-esteem in adolescents. Supportive parents and peers boost adolescents' self-esteem, which decreases their need to turn to material goods to develop positive self-perceptions. In a study with 12–18 year-olds, we find support for our view that self-esteem mediates the relationship between parent/peer influence and adolescent materialism. 相似文献
