Recent perspectives on social dominance in normative populations have suggested a developmental progression from using primarily coercive strategies to incorporation of more socially competent strategies to attain material and social resources. Parental influences on the resource control strategies children use have been proposed but not investigated empirically. The present study examined age- and gender-related differences in dominance strategies in 470 children from high-risk neighborhoods who were between 6 and 13 years of age, approximately half of whom had experienced maltreatment. A Q-sort measure of social dominance was developed and received preliminary support. Consistent with predictions from resource control theory, age-related differences in dominance-related behavior were demonstrated in both nonmaltreated and maltreated children. Maltreated children were more likely than nonmaltreated children to be identified as dominant bullies at any age. Dominance and bullying were not more likely to be associated for children who had experienced physical and sexual abuse relative to those who were neglected or emotionally maltreated. Results are discussed in terms of the influence of maltreatment on the social development of children, and intervention approaches for limiting these deleterious effects are recommended.  相似文献

Medically unexplained symptoms (MUS) are one of the key features of somatoform disorders. Although MUS are currently treated as both categorical (in terms of the diagnosis of somatoform disorders) and dimensional (in terms of quantitative measures of somatization/somatic symptom reporting), little is known about the empirical latent structure of MUS. Using taxometric analyses, the latent structure of somatic symptom reporting was analyzed with the Patient Health Questionnaire (PHQ)-15 in two student samples (N = 782 and N = 2,577) and a primary care sample (N = 519). We applied three popular taxometric methods: Maximum Eigenvalue (MAXEIG), Mean Above Minus Below a Cut (MAMBAC) and Latent-Mode (L-Mode). Simulation data were created to evaluate the appropriateness of the data for our analyses and to create the comparison curve fit index (CCFI) as an objective outcome measure. The results of all taxometric methods in any of the three data sets were in favor of a dimensional solution (CCFI < .50). Simulated taxonic and dimensional datasets differed substantially and the samples were appropriate for taxometric analysis. Accordingly, the latent structure of somatization/somatic symptom reporting as assessed by the PHQ-15 is dimensional in both primary care and student samples. Implications regarding the practical application as well as models of etiology and pathogenesis of somatic symptom reporting are discussed.

Few studies have been designed to assess the pathways by which risk factors are associated with symptoms of psychopathology across multiple domains, including contextual factors, parental depression, parenting, and child characteristics. The present study examines a cross-sectional model of risk factors for symptoms of Oppositional Defiant Disorder (ODD) in a diverse community sample of 796 four-year-old children. In the best-fitting model: (a) SES had indirect effects on contextual factors of stress and conflict, parental depression, and parenting factors including hostility, support, and scaffolding; (b) stress and conflict had both direct effects on ODD symptoms, and indirect effects via parental depression and parenting; (c) parenting had direct effects on ODD symptoms and indirect effects via child effortful control (EC), negative affect (NA) and sensory regulation (SR); (c) NA, EC, and SR had direct effects on symptom frequency, and attachment had indirect effects via EC, and SR. These results highlight the importance of using a multi-domain model to examine risk factors for symptoms of ODD, and also provide information about areas to target in treatment.  相似文献

Against the view that trauma cripples the survivor??s ability to account for his or her own experience, Jean Améry, a survivor of Auschwitz, argued that trauma speaks a language of its own. In this language, what may be taken as a clinical symptom, the inability to let go of a traumatic past, is actually an ethical stance on behalf of history??s victims. Améry wrote about aging in similar terms. Aging and death are an assault on the values of life, an assault that Améry rejected with equal vigor, and in much the same terms, as he rejected the history that does not stop with the Holocaust. In the second case, Améry is mistaken. Aging and death, allowed to proceed at a natural pace, serve life, the succession of generations. This argument is pursued by comparing Améry??s position with that of a large group of Holocaust survivors. It may appear as if Améry??s argument about the Holocaust has little to do with his argument about aging. In fact, they are related, to the detriment of both arguments.  相似文献

Iacobucci (2012) provides a conceptually appealing, readily implemented measure to assess mediation for a far wider range of data type combinations than traditional OLS-based analyses permit. Here, we consider potential applications and extensions along several lines, particularly in terms of random utility models, simulation-based estimation, and potential nonlinearities, as well as some methodological and cultural impediments.  相似文献

Numerous studies have indicated that maintaining a fear memory after retrieval requires de novo protein synthesis. However, no study to date has examined how the temporal dynamics of repeated retrieval events affect this protein synthesis requirement. The present study varied the timing of a second retrieval of an established auditory fear memory and followed this second retrieval with infusions of the protein synthesis inhibitor anisomycin (ANI) into the basolateral amygdala. Results indicated that the memory-impairing effects of ANI were not observed when the second retrieval occurred soon after the first (within 1 h), and that the inhibitor gradually regained effectiveness as the retrieval episodes were spaced further apart. Additionally, if the second of the closely timed retrievals was omitted prior to ANI infusions, long-term memory deficits were observed, suggesting that the altered effectiveness of ANI was due specifically to the second retrieval event. Further experiments revealed that the second retrieval was not associated with a change in Zif268 protein expression but did produce a rapid and persistent dephosphorylation of GluR1 receptors at Ser845, an AMPAR trafficking site known to regulate the stability of GluR2 lacking AMPARs, which have been shown to be important in memory updating. This suggests that the precise timing of multiple CS presentations during the reconsolidation window may affect the destabilization state of the memory trace.  相似文献

Abstract

Sales representative motivation, satisfaction, and performance have been topics of considerable interest to managers and researchers alike for many years. Recently researchers have borrowed conceptualizations from organizational behavior and applied them successfully in the sales setting. For the most part, research on work-related sales representative motivation has focused on either the “expectancy” approach or the “job characteristics” approach. A brief overview is presented, followed by an assessment of the validity of the core dimensions found in the increasingly popular Job Diagnostic Survey in a sales representative context. The managerial implications of the assessment are also discussed.  相似文献

Abstract

When the phenomenological method is applied to mental phenomena their object aspect becomes apparent in a way that contrasts with their meaning aspect. William James described this objective aspect of mental life as early as 1904, but it seems to have been overlooked as an approach to psychopathology. In stepping outside of the natural attitude and directly viewing psychopathology, a hidden, “tangible,” element of inner turmoil is disclosed that is described here as a Phenomenologically Observable Dictate or POD. The technique for dealing with PODs is described. The author claims that the technique opens new avenues of access to some forms of psychopathology, although it does not consist of a complete therapy unto itself.  相似文献

We conducted a meta-analysis of research on hindsight bias to gain an up-to-date summary of the overall strength of hindsight effects and to test hypotheses about potential moderators of hindsight distortion. A total of 95 studies (83 published and 12 unpublished) were included, and 252 independent effect sizes were coded for moderator variables in 3 broad categories involving characteristics of the study, of measurement, and of the experimental manipulation. When excluding missing effect sizes, the overall mean effect size was Md = .39 with a 95% confidence interval of .36 to .42. Five main findings emerged: (a) effect sizes calculated from objective probability estimates were larger than effect sizes calculated from subjective probability estimates; (b) effect sizes of studies that used almanac questions were larger than effect sizes of studies that used real-world events or case histories; (c) studies that included neutral outcomes resulted in larger effect sizes than studies that used positive or negative outcomes; (d) studies that included manipulations to increase hindsight bias resulted in significantly larger effect sizes than studies in which there were no manipulations to reduce or increase hindsight bias; and (e) studies that included manipulations to reduce hindsight bias did not produce lower effect sizes. These findings contribute to our understanding of hindsight bias by updating the state of knowledge, widening the range of known moderator variables, identifying factors that may activate different mediating processes, and highlighting critical gaps in the research literature.  相似文献

Abstract

This study was aimed at developing a measure of Kelly's concept of dispersion of dependency and providing evidence for its usefulness in differentiating degree of dispersion of dependency. Smith and Grassle's (1977) adaptation of Hurlbert's diversity index, a measure used by biologists to differentiate degrees of species diversity, was applied to dependency grids, specifically “being helped” grids. The diversity index was shown to be both useful in differentiating prototypes of relatively dispersed and undispersed grids and robust. Furthermore, evidence was provided for its predictive validity using predictions made by Kelly concerning dependency construing associated with differences in dispersion of dependency. Greater dispersion of dependency was related to making more discriminations about dependencies, and undispersed dependency was related to relatively impermeable and preemptive construing. Thus the measure was shown to be satisfactory for identifying dispersion of dependency, such that, used in this context, it could be aptly renamed the dispersion of dependency index.  相似文献
