We investigated a total of 4997 postings on an extreme right‐wing Internet discussion board with regard to the groups and themes mentioned. The most frequently mentioned target groups were Africans, Jews, Muslims, Poles, and Turks; the most prominent themes and contexts were conspiracy, criminality, exploitation, threats to German identity, infiltration, mind control and harassment, procreation, rape, and sex. We analysed in detail postings about Africans/Blacks and Jews, that is target groups that were the most clearly connected to particular themes. The analysis reveals that extreme right‐wing discourse essentializes the target groups of Jews and Africans/Blacks and ascribes them immutable group‐specific attributes that effectively make them ‘natural kinds’. The group of Jews appears as a kind of their own with super‐human powers and influence. Africans and Blacks are despised, firstly because their essential characteristics prohibit them to be categorically mixed with Germans (i.e. to become German by nationality) due to their incompatible essence, and secondly when they procreate with Whites. Such procreation produces ‘bastards’ that are met with disgust. We argue that essentialist thinking about social and ethnic groups explains a good part of their rejection by right‐wing followers.

Philosophers and social scientists have recently turned to Lewis sender–receiver games to provide an account of how lexical terms can acquire meaning through an evolutionary process. However, the evolution of meaning is contingent on both the particular sender–receiver game played and the choice of evolutionary dynamic. In this paper I explore some differences between models that presume an infinitely large and randomly mixed population and models in which a finite number of agents communicate with their neighbors in a social network. My results show that communication with neighbors is more conducive to the evolution of meaning than communication with strangers. Additionally, I show that the behavior of the system is highly dependent on the topological structure of the social network. I argue that a specific class of networks—small world graphs—is especially conducive to the evolution of meaning. This is because small world graphs have a short characteristic path length while still maintaining a high degree of correlation between neighbors. Since many actual social networks, such as friendship networks and nervous systems, are conjectured to be small world structures, these results indicate that these networks are quite hospitable to the efficient evolution of meaning.  相似文献

A simple rule of probability revision ensures that the final result ofa sequence of probability revisions is undisturbed by an alterationin the temporal order of the learning prompting those revisions.This Uniformity Rule dictates that identical learning be reflectedin identical ratios of certain new-to-old odds, and is grounded in the oldBayesian idea that such ratios represent what is learned from new experiencealone, with prior probabilities factored out. The main theorem of this paperincludes as special cases (i) Field's theorem on commuting probability-kinematical revisions and (ii) the equivalence of two strategiesfor generalizing Jeffrey's solution to the old evidence problem tothe case of uncertain old evidence and probabilistic new explanation.  相似文献

The Bureau of Justice Statistics estimates that approximately 1 in every 50 youth in the U.S. had a parent in State or Federal prison in 1999. Studies of children of incarcerated parents suggest that these youth are at risk for experiencing emotional and behavioral problems. Using a sample of 258 adolescents receiving routine mental health services, this study explored: (1) differences in demographic characteristics, lifetime exposure to risk factors, recent stressful life experiences, and clinical profiles of adolescents with and without a history of parental incarceration; and (2) the effect of parental incarceration relative to other risk factors on levels of emotional and behavioral problems and treatment outcomes. Nearly half (43%) of the youth studied had experienced the incarceration of one or both parents. Youth who experienced parental incarceration had been exposed to significantly more risk factors during their lifetimes including parental substance abuse, extreme poverty, and abuse or neglect. They were more likely than other treated youth to present with attention-deficit/hyperactivity and conduct disorders and less likely to have major depression. Findings provide preliminary evidence that parental incarceration may have a discrete negative effect on certain outcomes of treatment.  相似文献

Alexithymia and individual differences in emotional expression   总被引:1,自引:0,他引:1  
Two studies examined verbal and nonverbal expression in relation to facets of alexithymia. Participants were videotaped while they talked about negative and positive events that had happened to them. Persons high in difficulty identifying feelings were less emotionally expressive, nonverbally, of positive emotion during a positive talk, and of negative emotion during a negative talk. Other facets of alexithymia were not independently related to expressiveness. Verbal expressiveness was not independently related to any facet of alexithymia. Study 2 showed that these relationships were independent of whether the participant was alone or with another. The implications for the understanding of the nature of the deficit in alexithymia, and of the effects of disclosure are discussed.  相似文献

Prior research on backing-up behavior has indicated that it is beneficial to teams (C. O. L. H. Porter, 2005; C. O. L. H. Porter et al., 2003). This literature has focused on how backing-up behavior aids backup recipients in tasks in which workload is unevenly distributed among team members. The authors of the present study examined different contexts of workload distribution and found that, in addition to the initial benefits to backup recipients, there are initial and subsequent costs. Backing-up behavior leads backup providers to neglect their own taskwork, especially when workload is evenly distributed. Team members who receive high amounts of backing-up behavior decrease their taskwork in a subsequent task, especially when a team member can observe their workload. These findings indicate that it is important to consider both the benefits and costs of engaging in backing-up behavior.  相似文献

We investigated children’s understanding of directed motion events using an imitation choice paradigm. A total of 34 children (mean age 33 months) watched a model act out an event containing a manner of motion (hopping or sliding), a motion path (up or down a ramp), and a goal (in or on a bowl). On the children’s apparatus, the locations of the goal objects were different from the model so that the children needed to choose whether to imitate the path or the goal of the model’s event. Children’s choice of which component to imitate, therefore, reflects how they prioritize these event components. Most children showed no bias to imitate the goal of the event and, instead, preferred to imitate the model’s path at the expense of the model’s goal. However, children who spontaneously played with the goal objects during a free play session showed a diminished path preference, choosing to imitate path and goal components equally often. We suggest that children’s prioritization of information within an event depends on how that information is structured within the event itself.  相似文献

The metaphor is typically viewed as a verbal form of expression in traditional talk therapies. However, this definition excludes nonverbal metaphors that children use when they express themselves through play. In this article, the authors examine the use of therapeutic metaphors, both verbal and nonverbal, with children. The roles of the child, counselor, and family in treatment are discussed, along with the benefits and limitations of using therapeutic metaphors with children. The use of quantitative, qualitative, and integrated methods for studying children's use of verbal and nonverbal metaphors in counseling is also examined.  相似文献

This study documents significant associations among lifetime abuse experiences, psychiatric diagnoses, and sexual risk behaviors in a multiethnic community sample of young men and women (N = 1803) in South Florida. Self-report data were collected via structured interviews as part of a longitudinal follow-up of a larger school-based study. Participants were grouped according to extent of lifetime abuse experiences. Cumulative lifetime abuse experiences were associated with increased risk for a broad range of individual lifetime psychiatric disorders, as well as cumulative lifetime psychiatric disorders. Both cumulative abuse experiences and cumulative psychiatric disorders were independently associated with (a) higher levels of sexual risk behaviors and (b) higher risk for lifetime sexually transmitted diseases (STDs). Implications for selective prevention of sexual risk behaviors and STDs among young adults with histories of abuse and psychiatric disorders are discussed.  相似文献
