Flashbacks are a defining feature of posttraumatic stress disorder (PTSD), but there have been few studies of their neural basis. We tested predictions from a dual representation model of PTSD that, compared with ordinary episodic memories of the same traumatic event, flashbacks would be associated with activity in dorsal visual stream and related areas rather than in the medial temporal lobe. Participants with PTSD, with depression but not PTSD, and healthy controls were scanned during a recognition task with personally relevant stimuli. The contrast of flashbacks versus ordinary episodic trauma memories in PTSD was associated with increased activation in sensory and motor areas including the insula, precentral gyrus, supplementary motor area, and mid-occipital cortex. The same contrast was associated with decreased activation in the midbrain, parahippocampal gyrus, and precuneus/posterior cingulate cortex. The results were discussed in terms of theories of PTSD and dual-process models of recognition. 相似文献

Anger can be defined as an emotion consisting of feelings of variable intensity, from mild irritation or annoyance to intense fury and rage. Borderline personality disorder (BPD) is characterized by impulsivity and instability of interpersonal relationships, of self-image, and of negative affects. Borderline personality and trait anger are often observed together. The present study examined the extent to which a genetic association explains the covariation between a trait measure of borderline personality and trait anger. To this end, self-report data of 5,457 twins and 1,487 of their siblings registered with the Netherlands Twin Register and the East Flanders Prospective Twin Survey were analyzed using genetic structural equation modeling. A significant phenotypic correlation was observed between the two traits (rP = .52). This correlation was explained by genetic (54%) and by environmental influences (46%). A shared genetic risk factor is thus one of the explanations for the covariation of borderline personality and trait anger. 相似文献

The authors compared parent-related perceptions by hospitalized adolescents (i.e., who were admitted to a specialized psychiatric unit; n = 50) and delinquent adolescents (i.e., who were placed at a juvenile treatment institution; n = 51) with adolescents from the general population (n = 51). All adolescents completed a broad set of measures of attachment, perceived parenting, and separation–individuation. Contrary to initial expectations, hospitalized adolescents scored higher than controls on indices of excessive autonomy. Ambivalence regarding issues of interpersonal closeness and distance was found among delinquent adolescents. In addition, hospitalized and delinquent adolescents were found to be struggling, each in their specific way, with attachment-related experiences of trauma. Finally, delinquent adolescents also showed a stage-appropriate form of potentially adaptive narcissism. These findings add to the growing consensus in the literature that associations between adolescent psychopathology and parent-related perceptions are typically complex and somewhat counterintuitive. 相似文献

This research examined how performance feedback moderates the effects of individuals' achievement goals on information exchange when carrying out a novel and complex task. Experiment 1 demonstrated that mastery goal individuals who received positive performance feedback gave less modified information about their task performance to their exchange partner relative to both mastery goal individuals who received negative feedback and performance goal individuals (who received either negative or positive feedback). In Experiment 2, we found that relative to performance goals, mastery goals led to a stronger reciprocity orientation and a weaker exploitation orientation. Also, mastery goal individuals provided information of higher quality than performance goal individuals, thereby explaining the observed findings in Experiment 1. 相似文献

This enquiry concerning the principles of cultural norms and values focuses on the impact of mortality and uncertainty salience on people’s reactions to events that violate or bolster their cultural norms and values. Five experiments show that both mortality and uncertainty salience influence people’s reactions to violations and bolstering of their cultural worldviews, yielding evidence for both terror and uncertainty management theories. Interestingly, the five experiments consistently reveal that uncertainty salience has a bigger impact on people’s reactions than mortality salience, suggesting that the former may be a more important antecedent of reactions to norms and values than the latter. Findings further suggest that uncertainty salience did not instigate death-thoughts whereas reactions to norms and values were stronger among mortality salient participants who thought of uncertainty as a result of the mortality salience manipulation than mortality salient participants who did not think of uncertainty following this manipulation. Implications are discussed. 相似文献

In previous studies we demonstrated that the speech of a language-acquiring child and that of her parent can be characterized as a transactional process of dynamic adaptation. We reported a striking attunement between child and parent in the global development of mean length of utterance and utterance length between the ages of 1.5 and 2.5 years. Here we present a reanalysis of these data, focusing on the utilization of different categories of utterance length. In particular we analyzed the temporal structure of the dialogue on the linguistic level using the technique of cross-recurrence quantification. This type of analysis enabled us to study the interaction between interlocutors at the microlevel, revealing the dynamics of child-parent conversation and how this changes over time. Results showed decreasing values for measures quantifying the vertical line structures as well as an increasing average length of the diagonal lines in the recurrence plot. This was interpreted as indicating an increasing flexibility in the patterns of parent-child dialogue over the period of 1 year. 相似文献

Self-Control and Child Abuse Potential in Mothers with an Abuse History and Their Preschool Children
We examined whether physically and sexually abused mothers display lower levels of self-control, whether this explains their higher tendency to abuse their own children, and if this results in lower levels of self-control among their children. In a cross-sectional study, 40 abused and 47 matched, non-abused mothers completed validated self-control and child abuse potential questionnaires. Their preschool children (2.3–3.7 years) were tested for self-control with the effortful control battery and delay of gratification test. Relationships and mediations were tested using stepwise regression analyses and bootstrap mediation tests, while controlling for potential confounders. Mothers with a history of abuse had a significantly higher potential to abuse their children (p < .001) and lower levels of self-control (p < .05) compared to non-abused mothers. Maternal self-control predicted child abuse potential (p < .001) while controlling for maternal history of abuse, revealing that self-control partially mediated the relation between past abuse and current abuse potential. Next, child abuse potential was found to be a borderline significant predictor of child self-control (p = .05) on the delay of gratification task but not on the effortful control battery. We did not discover a correlation between child self-control and maternal self-control. These findings suggest that self-control may be a potentially important mechanism in the intergenerational cycle of child abuse. Further investigation on the topic is needed to confirm this hypothesis, for example through investigating the impact of parental self-control training on abusive parenting and children’s self-control development. Improved child self-control measures or focusing on older children is expected to address the key limitations of the current study. 相似文献
