Prenatal stress and risk for psychopathology: specific effects or induction of general susceptibility? 总被引:10,自引:0,他引:10
This review focuses on prenatal stress as a risk factor for psychopathology. Evidence from animal studies is summarized, and the relevance of prenatal stress models in animals for human studies is discussed. In the offspring of prenatally stressed animals, overactivity and impaired negative feedback regulation of the hypothalamic-pituitary-adrenal axis are consistent findings and may reflect a pathophysiological mechanism involved in the development of psychopathology. Reduced activity of the opioid GABA/benzodiazepine, serotonin, and dopamine systems and increased activity of the sympathico-adrenal system have been found as well. These alterations have been linked to a diverse spectrum of psychopathology. Therefore, the evidence supports the view that exposure to prenatal stress may result in a general susceptibility to psychopathology, rather than exerting a direct effect on a specific form of psychopathology. 相似文献

The present study tested the hypothesis that positive mood facilitates cognitive flexibility in categorization, i.e., positive mood enhances the ability to categorize flexibly at broad and narrow levels contingent on task requirement. The study was a conceptual replication of the 1990 work by Murray, Sujan, Hirt, and Sujan. Unlike the original study, it was carried out on the WWW with some modifications in the procedure. Participants were 29 women and 132 men whose average age was 29 yr. They were put into a positive, negative, or neutral mood using the Velten technique. Mood was measured with standard mood scales. Subjects then listed similarities differences between two entertainment TV shows. Contrary to the prediction, participants in a positive mood did not list a higher number, more diverse, or more unusual similarities and differences between the shows, and they were not faster than participants with neutral or negative moods. It is concluded that the influence of mood on cognitive flexibility needs to be reconsidered. In research, temporal aspects of categorization performance as well as a wider range of mood valences should be taken into account. 相似文献

The present paper is a first attempt to integrate the classical brain lesion behavioral impairment approach of functional neuroanatomy and the electrophysiological brain mapping approach in the domain of syntactic processing. In a group of normal age-matched controls we identified three electrophysiological components previously observed in correlation with language comprehension processes: an early left anterior negativity normally seen in correlation with syntactic first-pass parsing processes (ELAN), a centroparietal negativity seen in correlation with processes of lexical-semantic integration (N400), and a late centroparietal positivity observed in correlation with secondary syntactic processes of reanalysis and repair (P600). The early left anterior negativity was absent in a patient with an extended lesion in the anterior part of the left hemisphere sparing the temporal lobe, although the late centroparietal positivity and the centroparietal N400 were present. In a patient with a left temporal-parietal lesion the early left anterior negativity was found to be present, whereas the N400 component was absent. These findings suggest that first-pass parsing and secondary processes are subserved by distinct brain systems. 相似文献

Previous experimental research on the effects of incorrect intensity expectations of aversive events can be criticized because intensity expectations were not manipulated independently from changes in objective intensity. The present study aims at investigating the effects of incorrect intensity expectations on the immediate and later responses to a painful stimulus, and on the acquisition of anticipatory responses, with proper experimental control. Subjects (n = 62) received 20 painful stimuli of varying intensity. In the control group intensities were correctly signalled on all trials by an analogue signal. On 3 trials the signal was too large in the overprediction condition, and too small in the underestimation condition. Underpredicted painful experiences were related to subsequent higher pain responses on the physiological level, but not on the subjective level; and to increased anticipatory responses (increased pain expectations, uncertainty, subjective fear, skin conductance responses). Skin conductance level also indicated increased fear after underpredicted experiences. Overpredicted painful experiences were related to a faster decrease in subjective fear compared to the control group, but did not influence other variables. The findings support the notion that underpredictions contribute to the acquistion of fear and disrupt habituation processes. The asymmetrical processing of the two kinds of incorrectly predicted experiences is discussed. 相似文献

A study in the U.S.–Mexican intergroup context examined how collective relative gratification (RG) versus deprivation affects the relationship between intergroup contact and interpersonal closeness and subtle prejudice towards an out-group. Participants were Mexican university students in Mexico (N = 239) and non-Mexican students in California (N = 90). As predicted, Mexicans experienced less gratification/higher relative deprivation (RD), and low quality intergroup contact and expressed lower interpersonal closeness and higher subtle prejudice than U.S. Americans. Differences between countries were larger amongst participants reporting higher RD. Second-stage moderated mediation analysis showed that the mediating effects of contact between country and interpersonal closeness and subtle prejudice, respectively, were larger amongst participants who felt relatively gratified than those who felt relatively deprived. These findings underline the importance of recognizing the moderating effect of differences in the RG versus RD levels of minority and majority groups when anticipating the potential benefits of intergroup contact for prejudice reduction. 相似文献

Effects of family interaction on the child's behavior in single-parent or reconstructed families 总被引:2,自引:0,他引:2
The effects of the family interaction on children's behavior were studied in single-parent or reconstructed families (N = 63) in a white population in Finland. The focus was on the spousal and the parent-child interaction. Teachers assessed children's behavior and parents were interviewed. The interviews were analyzed qualitatively using the grounded-theory method. The boundary ambiguity theory developed by Pauline Boss was used to examine the interaction in the families. About two fifths of the parents reported that their spousal interaction was good, family boundaries were clear, and the children were taken care of together. Another two fifths interacted only because of the child and family boundaries were ambiguous. In 14 families the involvement of the noncustodial parent was both physically and psychologically low. The physically close but psychologically distant parent-child interaction seemed to affect the child's behavior detrimentally, whereas children with physically and psychologically close interaction with their parents showed less behavioral problems. The children with behavioral problems were more likely to have problems with both parents. They were also more likely to have a stepparent with whom they had conflicts. In conclusion, a good interaction between the parents and clarified family boundaries protect children's mental health after their parents' divorce or separation. 相似文献

The Induction of Mood via the WWW 总被引:1,自引:0,他引:1

Five experiments explored the methodology of Web-based mood induction and yielded empirical evidence for its feasibility and its limits. Study 1 examined the suitability of the Velten method and mood-suggestive photographs to induce both positive and negative moods. Negative mood was successfully induced, while the positive mood induction failed. In Study 2, cartoons successfully ameliorated mood, whereas jokes were ineffective. In Study 3, associations with affectively valenced words were not suitable in producing a positive or a negative mood. In Study 4, picture-illustrated emotive texts successfully induced a positive and a negative mood. In Study 5, valence and arousal ratings were obtained for the stimuli used in Study 1 and 3. Based on the results, recommendations for the application of online mood induction procedures are given. 相似文献

A single-case design was used to examine the benefits of cognitive behaviour therapy (CBT) in the treatment of two patients with atopic dermatitis (AD). Improvements were indicated for both cases in global outcome measures, with reductions in anxiety, depression and stigmatization beliefs and improvements in quality of life. Self-rated AD severity remained relatively stable across treatment time. For both cases, treatment gains were particularly evident in terms of reducing avoidance behaviours. The findings were discussed in relation to the need for CBT as an adjunct treatment for patients with AD and its potential role in improving psychological functioning. 相似文献

This paper explores the ramifications of excessive use of media on personality development, the development of symbolic and thinking functions and on psychic reality. In doing so, the questions of whether there are specific media objects possessing an intrinsic symbolic quality, and which attachments in the inner world of a child/adolescent can be mobilized or destroyed are discussed. By selecting specific material, computer gamers use their game to activate the field of a personal psychic reality. Hereby, they attempt some kind of self‐healing. However, after leaving the game, conflicts and traumata re‐enacted but unresolved in the game disappear from their temporary representation without generating any resonance in the gamer's psychic experience. Consequently, although states of mind and affects are activated in the computer game, their processing and integration fail; the game results in a compulsive repetition. The construction and consolidation of retrievable maturation and structural development, the representation of the unrepresentable, succeed in the context of the triangulating analytic relationship, initially through a jointly performed symbolic and narrative re‐experience or the recreation of the game. Theoretical considerations are illustrated by means of clinical vignettes. 相似文献
