The American and Canadian standardization samples for the fourth edition of the Wechsler Intelligence Scale for Children were
used to ascertain the prevalence of “seemingly anomalous” Full Scale IQ (FSIQ) scores for all possible sums of scaled scores
combinations of the Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index.
About 1% of FSIQ scores in both samples were anomalous (that is, fell outside the range of the four indices). Interestingly,
the prevalence of anomalous scores was higher at the extremes of the FSIQ distribution. Moreover, anomalous FSIQ scores occurring
above or below the mean of the FSIQ distribution (that is, 100) were larger or smaller, respectively, than any of the four
indices. Furthermore, if the range of the four indices did contain the FSIQ (the non-anomalous case), when the FSIQ was below
or above 100 it tended to be located distally in the half-segment of the range furthest below or above 100, respectively.
A non-technical intuitive analogy from Olympic sports and a statistical explanation for the findings are provided. Important
implications for practitioners are also presented.

The authors examined the relationship between psychological strain, emotional dissonance and emotional job demands during a working day of 65 Dutch (military) police officers, using a 5-day diary design. We hypothesized that emotional dissonance partly mediated the relationship between psychological strain at the start and at the end of a work shift. We also tested the mediating role of emotional dissonance between emotional job demands and psychological strain at the end of a work shift. Results of structural equation modeling analyses showed that psychological strain at the start of a work shift had a positive effect on the experience of emotional dissonance and psychological strain at the end of a work shift. Emotional dissonance partly mediated the relationship between psychological strain at the start and psychological strain at the end of a work shift. Results are discussed in light of conservation of resources theory (Hobfoll, S. E. (1988). The ecology of stress. New York: Hemisphere Publishing Corporation). 相似文献

Tics represent a complex class of behaviors that have a neurobiological origin and are influenced by factors both internal and external to the individual. One factor that has gained recent attention is the premonitory urge. Contemporary behavioral models suggest that some tics are preceded by aversive somatic urges that increase in severity when tics are suppressed and are attenuated by performance of the tic. It has been proposed that the removal of premonitory urges may strengthen or maintain tics via negative reinforcement. This investigation is the first to empirically evaluate the effect of tic suppression on the premonitory urge phenomenon. Five children and adolescents, ages 8–17 years, participated in the study. Using an ABAB reversal design, tic frequency and subjective premonitory urge ratings were recorded under conditions of free-to-tic baseline (BL) and reinforced tic suppression (differential reinforcement of zero-rate behavior). Results show that four of the five children demonstrated reliable suppression. Of the four children who achieved suppression, three demonstrated a pattern in which subjective urge ratings were higher during suppression than during BL. Results provide preliminary support for the negative reinforcement view of tic function for some children. 相似文献

In this article, the Linking Human Systems (LINC) Community Resilience model, a theoretical framework for initiating and sustaining change in communities that have undergone rapid and untimely transition or loss, is presented. The model assumes that individuals, families, and communities are inherently competent and resilient, and that with appropriate support and encouragement, they can access individual and collective strengths that will allow them to transcend their loss. This competence can be nurtured by helping people regain a sense of connectedness with one another; with those who came before them; with their daily patterns, rituals, and stories that impart spiritual meaning; and with tangible resources within their community. Rather than imposing artificial support infrastructures, LINC interventions engage respected community members to act as natural agents for change. These "community links" provide a bridge between outside professionals, families, and communities, particularly in circumstances in which outside intervention may not be welcomed. The article illustrates how LINC interventions successfully have been used in communities around the world. 相似文献

This article discusses the development, process, and impact of a mentoring group for family therapists of color. A within-group process for trainees of color in a predominantly White institution can provide a valuable resource for support, validation, empowerment, and collective action. The article examines how such mentoring promotes the effectiveness of therapists of color, as well as the practices and goals of social justice and diversity within training institutions and the field in general. Reflections and recommendations for implementing such a group are offered, as well as a personal narrative of a group member's experience of finding her voice in the group. 相似文献

After reviewing Engel's bio-psycho-social proposal and Kandel's "principles for an integration between mind and brain," the author introduces a set of akin propositions that aim at integrating neurosciences, genetics, the mind, and the social world into a succinct set of systemic formulations focusing on interlevel interfaces, with profound implications for the training, practice, and research in the field of family processes and therapy. 相似文献

Preliminary evidence that acute and chronic daily psychological stress affect sexual arousal in sexually functional women 总被引:1,自引:0,他引:1
It is assumed that psychological stress may inhibit sexual arousal in women. Research on the effect of (acute and chronic) psychological stressors on genital and subjective sexual arousal, however, is scarce. To investigate whether psychological stressors indeed inhibit sexual responding, sexually functional women were randomly assigned to an experimental condition (n=30) in which acute psychological stress was induced by a frustrating computer task or a control condition (n=29). After the acute psychological stress or control induction women were exposed to an erotic stimulus. Genital sexual arousal was assessed using vaginal photoplethysmography. Self-report ratings of subjective sexual arousal were collected after the erotic stimulus. Furthermore, women were post hoc divided into a 'low' and a 'high' chronic stress group, based on their pre-assessment scores on a chronic daily stress questionnaire. As predicted, it was found that women in the acute stress condition responded with lower levels of genital and subjective sexual arousal to an erotic stimulus than women in the control condition. In addition, women with high levels of chronic stress responded with lower levels of genital sexual arousal to an erotic stimulus than women with low levels of chronic stress. Chronic stress did not affect the level of subjective sexual arousal. 相似文献

目前关于生殖系基因治疗技术的伦理争论仍然十分激烈。这些争论的核心环节在于"父母生育一个健康血缘后代的需要"如何获得道德合理性论证,而目前很多研究在某种程度上忽视了这一问题,因而既不能解释这些伦理争论产生的原因,也不能为解决这一问题提供有效的指导。 相似文献
