People with higher social anxiety tend to reveal less information about themselves in interactions with strangers, and this appears to be part of a self-protective strategy adopted in situations in which the risk of negative evaluation is judged to be particularly high. This research examined whether a similar style of communication may be adopted by people with higher social anxiety in their close relationships, and whether it may be associated with decrements in the quality (support, depth, conflict) of these relationships. Over 300 people from the community completed a series of online questionnaires measuring social anxiety and depression, and disclosure in and quality of their close friendships and romantic relationships. After controlling for levels of depression, social anxiety was associated with a paucity of disclosure in both romantic relationships and close friendships in females, but not males. There was an indirect association between higher social anxiety and lower relationship quality (lower support, with a trend towards greater conflict) via lower self-disclosure in women's romantic relationships, but not their close friendships. Addressing disclosure in the context of close relationships may assist socially anxious women to develop more fulfilling and harmonious close relationships.  相似文献

This research examined generality of the phylogenetic rule that birds discriminate frequency ranges more accurately than mammals. Human absolute pitch chroma possessors accurately tracked transitions between frequency ranges. Independent tests showed that they used note naming (pitch chroma) to remap the tones into ranges; neither possessors nor nonpossessors were accurate at octave (pitch height) naming. Boreal chickadees discriminated frequency ranges less accurately than other birds; they tracked reward across several lower frequency ranges but failed at frequencies over 4000 Hz. The results revealed the error of describing species differences solely in terms of their discrimination of frequency ranges. Exceptions to the rule disappear when the rule is restated in terms of underlying mechanism: birds are superior to mammals in the ability to use absolute pitch height perception to discriminate pitches and ranges of pitches.  相似文献

Research indicates that upwards of 80% of our students experience the devastation of bullying during their school years. To date, research on bullying has mainly employed empirical methodologies, including quantitative and qualitative approaches. This research has largely concluded that bullying is situated in a lack of skill, understanding, or self-control and involves intentional action directed toward status dominance. Based upon these assumptions current anti-bullying strategies focus on training students toward more appropriate avenues of status acquisition and social interaction. Against the backdrop of an actual bullying encounter this paper employs a psychoanalytic philosophical lens to offer a fresh perspective on this enduring educational issue. Employing the philosophical work of Adam Phillips, Jessica Benjamin, and Emmanuel Ghent I ask the question: What is the desire to bully a desire for? Here I consider what is sought and what is at stake in the typical bullying encounter. Through careful analysis I argue that the domination represented in bullying is not simply situated in a lack of social skills or in disregulated aggression––skill deficiencies that require training. Instead, or perhaps in addition to these possibilities, I contend that bullying is foundationally a move toward establishing identity, a self. On this view bullying becomes an activity of self construction through attempted omnipotence. I argue that the status dominance inherent in bullying should be seen not as an end (a tool to secure resources or privilege), but as a means to something more foundational. I conclude that status dominance becomes a means toward the end of providing a secure place for the self to stand. Hence, instead of advocating that we train students to get along better this paper outlines the futility, as well as the insatiability of bullying, opening up new territory focused upon a re-construction of the bully through the relational bonding and differentiation available in the concrete Other.  相似文献

Iacobucci (2009, 2010) covers a number of important issues in the use of structural equation modeling and in so doing provides researchers with many useful insights and sensible suggestions. This commentary focuses on three issues where our views differ somewhat from those expressed in the target articles: SEM and causal inferences, sample size, and model fit. In addressing each of these issues, our perspectives do not so much contradict the views expressed by Iacobucci as they reflect a somewhat different conceptual emphasis.  相似文献

Youth departing from out-of-home care settings face numerous challenges as they adapt to new settings or return to placements that have been unsuccessful in the past. Although several thousand youth face this transition annually, little is known about their specific needs and risks at departure. To better identify needs and risks, we evaluated the discharge data of 640 youth served in a residential group care setting by addressing the following questions: (a) to what settings do youth depart following a stay in residential group care, (b) what are the demographic, family, educational, behavioral, and departure characteristics of youth at departure, and (c) do these characteristics differ for youth departing to different levels of restrictiveness? Results indicate significant differences on youth characteristics based on levels of restrictiveness at departure placement. As one might expect, youth departing to more restrictive placements presented a broad host of challenges across domains, while those departing to less restrictive settings demonstrated fewer needs and departed with greater educational and behavioral gains. Results provide support for the development and planning of targeted aftercare programs designed to promote the short and long term functioning of youth served in out-of-home care.  相似文献

Children in residential care are a heterogeneous population, presenting various combinations of risks. Existing studies on these children suggest high variability across multiple domains (e.g., academics, behavior). Given this heterogeneity, it is important to begin to identify the combinations and patterns of multiple risks, or risk profiles, these children present. The purpose of this study was to evaluate the academic and behavioral risk profiles of children entering residential care. Cluster analysis procedures using academic and behavior variables revealed three distinct profiles of children: Group 1: Average Janes, characterized by average academic skills, no behavior problems, and some demographic risks; Group 2: Academic Risks, characterized by low academics and increased rule-breaking behavior; and finally Group 3: Behavioral Risks, characterized by average academics and elevated behaviors. These preliminary finding are discussed along with limitations, directions for future research, and implications.  相似文献

Research has shown that Chinese students outperform students from several Western countries on mathematics performance while some evidence has suggested that Western students perform more strongly on tests of creativity. One potential mechanism for these differences may be a higher need for cognitive closure among Chinese students. The current research compared performance on tests of mathematics and creativity among 50 students of Chinese background and 49 Australian students of Anglo‐Saxon background. As predicted, Chinese students performed better on mathematics while Australian students performed better on the measure of creativity. Australian students also had a lower score on one subscale of the need for cognitive closure, preference for predictability. Across the sample, preference for predictability showed small but significant negative correlations with several measures of creativity and positive correlations with several measures of mathematics. These findings were interpreted with respect to characteristic educational practices in both nations.  相似文献

Analyses from the National Comorbidity Study Replication provide the first nationally representative estimates of the co-occurrence of impulsive angry behavior and possessing or carrying a gun among adults with and without certain mental disorders and demographic characteristics. The study found that a large number of individuals in the United States self-report patterns of impulsive angry behavior and also possess firearms at home (8.9%) or carry guns outside the home (1.5%). These data document associations of numerous common mental disorders and combinations of angry behavior with gun access. Because only a small proportion of persons with this risky combination have ever been involuntarily hospitalized for a mental health problem, most will not be subject to existing mental health-related legal restrictions on firearms resulting from a history of involuntary commitment. Excluding a large proportion of the general population from gun possession is also not likely to be feasible. Behavioral risk-based approaches to firearms restriction, such as expanding the definition of gun-prohibited persons to include those with violent misdemeanor convictions and multiple DUI convictions, could be a more effective public health policy to prevent gun violence in the population.
