Sleep disorders, such as insomnia and nightmares, are commonly associated with Borderline Personality Disorder (BPD) in adulthood. Whether nightmares and sleep-onset and maintenance problems predate BPD symptoms earlier in development is unknown. We addressed this gap in the literature using data from the Avon Longitudinal Study of Parents and Children (ALSPAC). Participants included 6050 adolescents (51.4 % female) who completed the UK Childhood Interview for DSM-IV BPD at 11 to 12 years of age. Nightmares and sleep onset and maintenance problems were prospectively assessed via mother report when children were 2.5, 3.5, 4.8 and 6.8 years of age. Psychopathological (i.e., emotional temperament; psychiatric diagnoses; and emotional and behavioural problems) and psychosocial (i.e., abuse, maladaptive parenting, and family adversity) confounders were assessed via mother report. In logistic regressions, persistent nightmares (i.e., regular nightmares at 3 or more time-points) were significantly associated with BPD symptoms following adjustment for sleep onset and maintenance problems and all confounders (Adjusted Odds Ratio = 1.62; 95 % Confidence Interval = 1.12 to 2.32). Persistent sleep onset and maintenance problems were not significantly associated with BPD symptoms. In path analysis controlling for all associations between confounders, persistent nightmares independently predicted BPD symptoms (Probit co-efficient [β] = 0.08, p = 0.013). Emotional and behavioural problems significantly mediated the association between nightmares and BPD (β =0.016, p < 0.001), while nightmares significantly mediated associations between emotional temperament (β = 0.001, p = 0.018), abuse (β = 0.015, p = 0.018), maladaptive parenting (β = 0.002, p = 0.021) and subsequent BPD. These findings tentatively support that childhood nightmares may potentially increase the risk of BPD symptoms in early adolescence via a number of aetiological pathways. If replicated, the current findings could have important implications for early intervention, and assist clinicians in the identification of children at risk of developing BPD.  相似文献

Are mechanisms for social attention influenced by culture? Evidence that social attention is triggered automatically by bottom‐up gaze cues and is uninfluenced by top‐down verbal instructions may suggest it operates in the same way everywhere. Yet considerations from evolutionary and cultural psychology suggest that specific aspects of one's cultural background may have consequence for the way mechanisms for social attention develop and operate. In more interdependent cultures, the scope of social attention may be broader, focusing on more individuals and relations between those individuals. We administered a multi‐gaze cueing task requiring participants to fixate a foreground face flanked by background faces and measured shifts in attention using eye tracking. For European Americans, gaze cueing did not depend on the direction of background gaze cues, suggesting foreground gaze alone drives automatic attention shifting; for East Asians, cueing patterns differed depending on whether the foreground cue matched or mismatched background cues, suggesting foreground and background gaze information were integrated. These results demonstrate that cultural background influences the social attention system by shifting it into a narrow or broad mode of operation and, importantly, provides evidence challenging the assumption that mechanisms underlying automatic social attention are necessarily rigid and impenetrable to culture.  相似文献

生物运动系在运动的生物体身的关键节点安置12~15个光点的运动痕迹形成的动画。研究表明光点生物运动包含了丰富的社会性信息,其社会性信息的识别涉及多个心理活动过程,其中大脑自上而下的知觉调控过程发挥重要作用。本研究通过两个实验探讨了表象预期在大脑自上而下调控光点生物运动性别信息识别的作用。结果发现:(1)表象预期能够加快男性生物运动的性别识别速度;想象中性形象被试倾向于将性别中立的生物运动识别为中性,而较少为男性或者女性。(2)表象预期条件和无表象预期条件下性别中立的光点生物运动性别类型识别都表现出“男性偏差”现象。(3)反应类型能够影响生物运动的性别识别。本研究有利于揭示大脑自上而下调控光点生物运动性别信息识别的心理机制。  相似文献

The goal of this study was to integrate the job demands-resources model and the conservation of resources model of job burnout into a unified theoretical framework. The data were collected through a mail questionnaire survey among nurses holding managerial positions in the Hospital Authority of Hong Kong. From a computer-generated random sample of nurses, 543 (84.3% women) returned usable surveys, amounting to a response rate of 24.2%. Structural equation modeling was used to test the proposed paths originating from job demands and job resources to the core job burnout dimensions, namely, emotional exhaustion and depersonalization. Results supported the integrated model, indicating that job demands and job resources had differing effects on the burnout dimensions. The effect of job demands was stronger and partially mediated the effect of job resources. Implications of the results from this study on management practices were discussed.  相似文献

Comparing two independent experiments following the same paradigm, the present article ponders the influence of constraints on graphic activity. A first study realized by Athènes et al. (2004) on the reproduction of simple graphic shapes revealed the presence of five preferential shapes when the effector was not constrained. With the forearm fastened, our results suggest that four only shapes are preferential when reproducing these same shapes. Overall, our findings suggest that the addition of a constraint related to the effector does not necessarily imply a negative effect on the graphic landscape. Were this assumption to be confirmed by full-fledged studies, it would be then possible to reveal new preferential shapes that are not spontaneously reproduced without additional constraints.  相似文献

The aim of this research was to study the influence of holiday's duration on children's attentional performances at school. Chronopsychological studies underlined a standard daily attention pattern striking a balance between the different rhythms of the child. This study aimed to answer two questions: the first one considered effect of holiday duration (15 days versus 10 days) on the standard pattern of children attention (returning from their holidays) by taking into account their level of education. The second one considered whether decline of attention on Friday (explained by phenomenon of anticipation of the weekend) was still present after 2 weeks of rest, whatever the children's level of education were. Two hundred and twenty-nine children aged from 6 to 11 took part to this study. Attention level was measured through cross-out tests, which children completed at school during the week following their holidays. The sample was divided into two (schooling) levels: from primary to early elementary (124 first-grade pupils) and late elementary (105 fifth-grade pupils). The study was conducted over 2 weeks, one following All Saints’ Day holidays (which are 10 days long) and one following the Easter holidays (which are 15 days long). The results showed that after a 10-day holiday, the youngest pupils obtained higher performances than after a 2-week holiday, except for Friday, which is considered in the literature as a particularly difficult moment. Furthermore, the pattern collectively admitted as standard was not observed after a 2-week holiday. For older pupils, attention was mobilized 5 consecutive days only after 2 weeks of rest. For all pupils, a 10-day holiday didn’t seem to allow synchronization of children's rhythms, and involved a lower level of attention at the end of week than after a 2-week holiday.  相似文献

Surrogate endpoints frequently substitute for rare outcomes in research. The ability to learn about completed suicides by investigating more readily available and proximate outcomes, such as suicide attempts, has obvious appeal. However, concerns with surrogates from the statistical science perspective exist, and mounting evidence from psychometric, neurochemical, genetic, and neuroimaging studies suggests that surrogates may be particularly problematic in suicide research. The need for greater phenotypic refinement of suicide-related behaviors, development of and adherence to a shared suicide nomenclature, and conservative interpretation of investigational results that are limited to the precise population and suicide-related behavior under examination are discussed.  相似文献

This paper exemplifies a secondary data analysis of context-specific differences in children's hyperactivity-impulsivity while controlling for informant-specific effects. Participants were boys and girls from the NICHD Study of Early Child Care and Youth Development who were measured in 1(st), 3(rd), and 5(th) grades. Latent factor models were structured using multi-informant reports including mothers, fathers, teachers, and observers. Temporal stability within a context was stronger than cross-context consistency, and the magnitude of longitudinal stability was higher in the home context compared to the school context. Controlling for informant-specific effects resulted in a significantly improved model fit and increased within-context stability. Our findings highlight the importance of considering both context and informant effects when studying longitudinal stability and change in personality development.  相似文献

This study examined several propositions of social cognitive career theory ( [Lent et al., 1994] and [Lent et al., 2000]) with a sample of 393 Mexican American college students. It was hypothesized that person input (i.e., age) and background contextual variables (i.e., Anglo orientation, Mexican orientation, familism, instrumentality, and expressivity) would predict career self-efficacy across Holland’s (1997) six RIASEC types. In addition, we examined the proposed relations between career self-efficacy, career interests, and career choice goal across the six RIASEC areas. Our results indicated that (a) Artistic, Social, Enterprising, and Conventional career models were similar across gender and university affiliation groups, (b) gender differences were found in the Realistic career model, (c) institutional affiliation differences were found in the Investigative career model, and (d) the models were a good fit to the data. Implications for future vocational research and career interventions are discussed.  相似文献

Body dissatisfaction, its risk factors and association with depressed mood have been well investigated in the West. However, more studies are needed to examine further the relation between body dissatisfaction and depressive symptoms and the factors influencing body dissatisfaction in non-Western cultures. The present study examined in a sample of Hong Kong Chinese adolescents the relation between body dissatisfaction and depressive symptoms, and the relation of maternal appraisal of their adolescent's figure to the adolescent's body dissatisfaction and depressive symptoms. We obtained information from 379 boys and 254 girls about their body dissatisfaction and depressive symptoms. Their mothers provided information about their appraisal of their adolescent's body shape and size compared to ideal. Body dissatisfaction was related to depressive symptoms in girls (B = 2.58, p <.01), but not in boys (B = -0.08, p >.10). Negative maternal appraisal did not have direct effects on adolescents' depressive symptoms (B = 0.14, p =.75), but the association between negative maternal appraisal and body dissatisfaction was significantly stronger in adolescents whose ideal was smaller than they perceived themselves to be (B = 0.32, p <.01) than those whose ideal was larger than their own perception (B = 0.14, p < .01). Our findings suggest that maternal appraisal had indirect effects on mood, acting through adolescents' body dissatisfaction, and that body dissatisfaction may be a sex-specific risk factor for depression. This study points to the need for testing and adapting programs to reduce body dissatisfaction particularly in girls at risk for depression, and to raise mothers' awareness of the link between their negative appraisals and their adolescents' body dissatisfaction and depressive symptoms.  相似文献
