Several positive functions have been ascribed to integrative internal dialogues (IDs), which are based on mutual openness to a partner's viewpoint and a readiness to consider his/her arguments in order to potentially modify one's own stance. As the technique of imagined intergroup contact (IIC) favorably influences attitudes towards outgroup members, it was hypothesized that IIC would have a beneficial impact on IDs with an outgroup member when the dialogue is focused on differences between ingroup and outgroup. In the experiment, 151 people (80 women) participated. It revealed that after IIC, both the dialogue author's confrontational attitude and the interlocutor's integrative attitude decreased. Thus, IIC made participants less inclined to gain an advantage over their imagined outgroup interlocutors and more inclined to give them freedom in IDs. However, the effect was significant only when the author's involvement in ID was high or medium.  相似文献

Humans gather most of their knowledge about the world, including objectively true facts and specific cultural norms, by observing and being taught by others. Some individuals are worthy teachers and objects of imitation, having knowledge of cultural practices and positive intentions to inform. Others are better ignored because they are ignorant, because they mean us harm, or simply because we do not wish to be “like them.” This study examines whether 16-month-olds are sensitive to the pro- or antisocial behavior of a source that demonstrates preference for two novel foods. Infants took the emotional reactions displayed by novel and previously prosocial sources, but not antisocial sources, into account when deciding what to eat. These results suggest that others’ social behavior influences infants’ likelihood to match their preferences, illustrating the influence of social evaluation on social learning.  相似文献

在生理水平的血管壁切应力属于优性因子,能促进血管重建,抑制内皮细胞凋亡,调节内皮细胞分泌功能,使内皮细胞形态产生适应性变化;而显著升高或降低的血管壁切应力则属于非优因子,导致高血压恶性循环发生、促进动脉粥样硬化及动脉血栓形成。实现切应力非优向优转化的重要途径是降低高血压和选择性阻断切应力对基因表达的调节  相似文献

睡眠不足会对人的认知、情感和人际交互产生诸多影响。这种影响在社会情绪层面表现为个体情绪共情和认知共情的减少,易激惹性与愤怒情绪的增加;在社会行为层面则表现为亲社会行为的减少和攻击行为的增加。在睡眠不足状态下,情绪系统和认知系统功能连接的减弱可能是这些变化的潜在机制。未来应结合生态效度较高的睡眠操作手段,系统考察睡眠不足如何导致各种高级社会情绪的改变,以及这些社会情绪的变化如何导致社会行为的变化。  相似文献

This study examined the quality of forensic interviews conducted by specially trained police officers in the Norwegian Barnahus between 2015 and 2017, using the sequential interview (SI) model, a Norwegian version of the extended interview model that has not previously been studied. Two hundred and seven interviews of alleged abused preschool children (3–7 years old) were selected from around the country. Developmental trends in interview dynamics and the pattern of disclosure were analyzed. Analyses showed that the interviews were long but involved few open-ended and many suggestive questions, especially in interviews with the youngest children who did not disclose. Because similar findings were obtained in previous studies of Norwegian interviews not using this model, the findings suggest that the SI interview model does little to improve the formal quality of forensic interviews with very young children, and show the need to develop new forms of interviewer training which are more intensive than those currently employed.  相似文献

As a core component of most cognitive diagnosis models, the Q-matrix, or item and attribute association matrix, is typically developed by domain experts, and tends to be subjective. It is critical to validate the Q-matrix empirically because a misspecified Q-matrix could result in erroneous attribute estimation. Most existing Q-matrix validation procedures are developed for dichotomous responses. However, in this paper, we propose a method to empirically detect and correct the misspecifications in the Q-matrix for graded response data based on the sequential generalized deterministic inputs, noisy ‘and’ gate (G-DINA) model. The proposed Q-matrix validation procedure is implemented in a stepwise manner based on the Wald test and an effect size measure. The feasibility of the proposed method is examined using simulation studies. Also, a set of data from the Trends in International Mathematics and Science Study (TIMSS) 2011 mathematics assessment is analysed for illustration.  相似文献

Through analyzing conflict narratives regarding Khao Phra Wihan, a territorial conflict important for nationalists in Thailand, this article aims to detangle how nationalization is experienced and performed on an individual level. In this article, the concept “affective self-nationalization” is proposed to analyze the emotional and embodied practices through which individuals fashion themselves into nationalized subjects. In Thailand, self-nationalization is instigated by the governing agency through repeated, regular, mandatory, public performances of loyalty through which individuals create the nation collectively. These performances create automatic feelings to the nation, establishes national others as fearsome, and rule through the basic human need of belonging. At the same time, individuals’ emotions shape the society through how they decide to perform nationalization. The concept of “affective self-nationalization” captures the connections between the official nationalizing program of “outside” society in a form of nationalist emotional socialization with individual experience of nationalizing.  相似文献

The study aims to investigate the quality of life (QOL) and the psychological situation in Chinese patients with rosacea. A total of 196 healthy controls and 201 rosacea patients were involved in the final analysis. The general information, the Dermatology Life Quality Index (DLQI) and the Hospital Anxiety and Depression Scale (HADS) were collected. Significantly higher DLQI, anxiety and depression score were observed in the rosacea group compared to the control group (p < .01). Total DLQI score of patients was positively related with anxiety (r = .526, p < .001) and depression scores (r = .399, p < .001) in HADS. Rosacea had significant psychological impact on Chinese patients and had substantial influence on their QOL. Physicians should address the psychosocial needs of rosacea patients as much as its physical symptoms.  相似文献

It is widely recognized that abdominal pain and discomfort are common problems in the United States and are often associated with negative quality of life. The prevalence of anxiety/depression elevations and disorders among persons with gastrointestinal disturbances (GI) is estimated to be at least two to three times the rate in the general population. Visceral sensitivity reflects anxiety about GI sensations and its accompanying contexts and often leads to worsening of sensations (e.g. bloating, upset stomach, diarrhea). Among individuals with GI symptoms, visceral sensitivity may be associated with interpreting common sensations as catastrophic which may be related to greater difficulties with emotion dysregulation (e.g. severe anxiety and depression). The current study evaluated the indirect association of visceral sensitivity via emotion dysregulation in relation to depression, anxious arousal, and social anxiety symptoms among 344 young adults with a current history of GI symptoms and problems. Results indicated an indirect effect of visceral sensitivity via emotion dysregulation. These findings provide novel empirical support for the association of visceral sensitivity with emotional distress symptoms among young adults with GI symptoms. Based on the results, targeting emotion dysregulation may be a promising health promotion tactic among young adults with GI symptoms and disorders.  相似文献

This study explored infant feeding practice meanings of HIV-positive mothers. Informants were eight black South African mothers (age range 18–29 years) enrolled in a mother-to-child transmission (MTCT) prevention programme. In-depth interviews on factors that influence exclusive breast-feeding were conducted with the mothers. Thematic analysis of the data yielded meanings around practices of knowledge contestation with health care providers and family, work demands, and personal preferences. Moreover, successful breast-feeding by mothers with HIV status may depend on addressing contradictory messages by health workers on infant feeding and community and family pressure to mix-feed the infant children.  相似文献
